SUPPLEMENTARY.
IT is told of the "Spectator," on his own high
authority, that having "read the controversies of some great men
concerning the antiquities of Egypt, he made a voyage to Grand Cairo on
purpose to take the measure of a pyramid, and that, so soon as he had set
himself right in that particular, he returned to his native country with
great satisfaction." My love of knowledge has not carried me
altogether so far, chiefly, I daresay, because my voyaging opportunities
have not been quite so great. Ever since my ramble of last year,
however, I have felt, I am afraid, a not less interest in the geologic
antiquities of Small Isles than that cherished by the "Spectator" with
respect to the comparatively modern antiquities of Egypt; and as, in a
late journey to these islands, the object of my visit involved but a
single point, nearly as insulated as the dimensions of a pyramid, I think
I cannot do better than shelter myself under the authority of the
short-faced gentleman who wrote articles in the reign of Queen Anne.
I had found in Eigg, in considerable abundance and fine keeping, reptile
remains of the Oolite; but they had occurred in merely rolled masses,
scattered along the beach. I had not discovered the bed in which
they had been originally deposited, and could neither tell its place in
the system, nor its relation to the other rocks of the island. The
discovery was but a half-discovery,—the half of a broken medal, with the
date on the missing portion. And so, immediately after the rising of
the General Assembly in June last [1845], I set out to revisit Small
Isles, accompanied by my friend Mr Swanson, with the determination of
acquainting myself with the burial place of the old Oolitic reptiles, if
it lay anywhere open to the light.
We found the Betsey riding in the anchoring ground at Isle
Ornsay, in her foul-weather dishabille, with her topmast struck and in the
yard, and her cordage and sides exhibiting in their weathered aspect the
influence of the bleaching rains and winds of the previous winter.
She was at once in an undress and getting old, and, as seen from the shore
through rain and spray,—for the weather was coarse and boisterous,—she had
apparently gained as little in her good looks from either circumstance as
most other ladies do. We lay stormbound for three days at Isle
Ornsay, watching from the window of Mr Swanson's dwelling the incessant
showers sweeping down the loch. On the morning of Saturday, the
gale, though still blowing right ahead, had moderated; the minister was
anxious to visit this island charge, after his absence of several weeks
from them at the Assembly; and I, more than half afraid that my term of
furlough might expire ere I had reached my proposed scene of exploration,
was as anxious as he; and so we both resolved, come what might, on
doggedly beating our way adown the Sound of Sleat to Small Isles. If
the wind does not fail us, said my friend, we have little more than a
day's work before us, and shall get into Eigg about midnight. We had
but one of our seamen aboard, for John Stewart was engaged with his potato
crop at home; but the minister was content, in the emergency, to rank his
passenger as an able-bodied seaman; and so, hoisting sail and anchor, we
got under way, and, clearing the loch, struck out into the Sound.
We tacked in long reaches for several hours, now opening up
in succession the deep withdrawing lochs of the mainland, now clearing
promontory after promontory in the island district of Sleat. In a
few hours we had left a bulky schooner, that had quitted Isle Ornsay at
the same time, full five miles behind us; but as the sun began to decline,
the wind began to sink; and about seven o'clock, when we were nearly
abreast of the rocky point of Sleat, and about half-way advanced in our
voyage, it had died into a calm; and for full twenty hours thereafter
there was no more sailing for the Betsey. We saw the sun set, and
the clouds gather, and the pelting rain come down, and night fall, and
morning break, and the noon-tide hour pass by, and still were we floating
idly in the calm. I employed the few hours of the Saturday evening
that intervened between the time of our arrest and nightfall, in fishing
from our little boat for medusæ with a
bucket. They had risen by myriads from the bottom as the wind fell,
and were mottling the green depths of the water below and around far as
the eye could reach. Among the commoner kinds,—the kind with the
four purple rings on the area of its flat bell, which ever vibrates
without sound, and the kind with the fringe of dingy brown, and the long
stinging tails, of which I have sometimes borne from my swimming
excursions the nettle-like smart for hours,—there were at least two
species of more unusual occurrence, both of them very minute. The
one, scarcely larger than a shilling, bore the common umbiliferous form,
but had its area inscribed by a pretty orange-coloured wheel; the other,
still more minute, and which presented in the water the appearance of a
small hazel-nut of a brownish-yellow hue, I was disposed to set down as a
species of beroe. On getting one caught, however, and transferred to
a bowl, I found that the brownish-coloured, melon-shaped mass, though
ribbed like the beroe, did not represent the true outline of the animal:
it formed merely the centre of a transparent gelatinous bell, which,
though scarce visible in even the bowl, proved a most efficient instrument
of motion. Such were its contractile powers, that its sides nearly
closed at every stroke, behind the opaque orbicular centre, like the legs
of a vigorous swimmer; and the animal, unlike its more bulky
congeners,—that, despite of their slow but persevering flappings, seemed
greatly at the mercy of the tide, and progressed all one way,—shot, as it
willed, backwards, forwards, or athwart. As the evening closed, and
the depths beneath presented a dingier and yet dingier green, until at
length all had become black, the distinctive colours of the acelpha,—the
purple, the orange, and the brown,—faded and disappeared, and the
creatures hung out, instead, their pale phosphoric lights, like the
lanthorns of a fleet hoisted high to prevent collision in the darkness.
Now they gleamed dim and indistinct as they drifted undisturbed through
the upper depths, and now they flamed out bright and green, like beaten
torches, as the tide dashed them against the vessel's sides. I
bethought me of the gorgeous description of Coleridge, and felt all its
beauty:—
They moved in tracks of shining white,
And when they reared, the elfish light
Fell off in hoary flakes.
Within the shadow of the ship
I watched their rich attire,—
Blue, glassy green, and velvet black:
They curled, and swam, and every track
Was a flash of golden fire. |
A crew of three, when there are watches to set, divides
wofully ill. As there was, however, nothing to do in the calm, we
decided that our first watch should consist of our single seaman, and the
second of the minister and his friend. The clouds, which had been
thickening for hours, now broke in torrents of rain, and old Alister got
into his water-proof oil-skin and souwester, and we into our beds.
The seams of the Betsey's deck had opened so sadly during the past winter,
as to be no longer water-tight, and the little cabin resounded drearily in
the darkness, like some dropping cave, to the ceaseless patter of the
leakage. We continued to sleep, however, somewhat longer than we
ought,—for Alister had been unwilling to waken the minister; but we at
length got up, and, relieving watch the first from the tedium of being
rained upon and doing nothing, watch the second was set to do nothing and
be rained upon in turn. We had drifted during the night-time on a
kindly tide, considerably nearer our island, which we could now see
looming blue and indistinct through the haze some seven or eight miles
away. The rain ceased a little before nine, and the clouds rose,
revealing the surrounding lands, island and main,—Rum, with its abrupt
mountain-peaks,—the dark Cuchullins of Skye,—and, far to the south-east,
where Inverness bounds on Argyllshire, some of the tallest hills in
Scotland,—among the rest, the dimly-seen Ben-Nevis. But long wreaths
of pale gray cloud lay lazily under their summits, like shrouds half drawn
from off the features of the dead, to be again spread over them, and we
concluded that the dry weather had not yet come. A little before
noon we were surrounded for miles by an immense but thinly-spread shoal of
porpoises, passing in pairs to the south, to prosecute, on their own
behalf, the herring fishing in Lochfine or the Gareloch; and for a full
hour the whole sea, otherwise so silent, became vocal with long-breathed
blowings, as if all the steam-tenders of all the railways in Britain were
careering around, us; and we could see slender jets of spray rising in the
air on every side, and glossy black backs and pointed fins, that looked as
if they had been fashioned out of Kilkenny marble, wheeling heavily along
the surface. The clouds again began to close as the shoal passed,
but we could now hear in the stillness the measured sound of oars, drawn
vigorously against the gunwale in the direction of the island of Eigg,
still about five miles distant, though the boat from which they rose had
not yet come in sight. "Some of my poor people," said the minister,
"coming to tug us ashore!" We were boarded in rather more than half
an hour after,—for the sounds in the dead calm had preceded the boat by
miles,—by four active young men, who seemed wonderfully glad to see their
pastor; and then, amid the thickening showers, which had recommenced heavy
as during the night, they set themselves to tow us unto the harbour.
The poor fellows had a long and fatiguing pull, and were thoroughly
drenched ere, about six o'clock in the evening, we had got up to our
anchoring ground, and moored, as usual, in the open tide-way between
Eilan Chasteil and the main island. There was still time enough
for an evening discourse, and the minister, getting out of his damp
clothes, went ashore and preached.
The evening of Sunday closed in fog and rain, and in fog and
rain the morning of Monday arose. The ceaseless patter made dull
music on deck and skylight above, and the slower drip, drip, through the
leaky beams, drearily beat time within. The roof of my bed was
luckily water-tight; and I could look out from my snuggery of blankets on
the desolations of the leakage, like Bacon's philosopher surveying a
tempest from the shore. But the minister was somewhat less
fortunate, and had no little trouble in diverting an ill-conditioned drop
that had made a dead set at his pillow. I was now a full week from
Edinburgh, and had seen and done nothing; and, were another week to pass
after the same manner,—as, for aught that appeared, might well happen,—I
might just go home again, as I had come, with my labour for my pains.
In the course of the afternoon, however, the weather unexpectedly cleared
up, and we set out somewhat impatiently through the wet grass, to visit a
cave a few hundred yards to the west of Naomh Fraing, in which it
had been said the Protestants of the island might meet for the purposes of
religious worship, were they to be ejected from the cottage erected by Mr
Swanson, in which they had worshipped hitherto. We re-examined, in
the passing, the pitch-stone dike mentioned in a former chapter, and the
charnel cave of Francis; but I found nothing to add to my former
descriptions, and little to modify, save that perhaps the cave appeared
less dark, in at least the outer half of its area, than it had seemed to
me in the former year, when examined by torchlight, and that the
straggling twilight, as it fell on the ropy sides, green with moss and
mould, and on the damp bone-strewn floor, overmantled with a still darker
crust, like that of a stagnant pool, seemed also to wear its tint of
melancholy greenness, as if transmitted through a depth of seawater.
The cavern we had come to examine we found to be a noble arched opening in
a dingy-coloured precipice of augitic trap,—a cave roomy and lofty as the
nave of a cathedral, and ever resounding to the dash of the sea; but
though it could have amply accommodated a congregation of at least five
hundred, we found the way far too long and difficult for at least the weak
and the elderly, and in some places inaccessible at full flood ; and so we
at once decided against the accommodation which it offered. But its
shelter will, I trust, scarce be needed.
On our return to the Betsey, we passed through a straggling
group of cottages on the hill-side, one of which, the most dilapidated and
smallest of the number, the minister entered, to visit a poor old woman,
who had been bed-ridden for ten years. Scarce ever before had I seen
so miserable a hovel. It was hardly larger than the cabin of the
Betsey, and a thousand times less comfortable. The walls and roof,
formed of damp grass-grown turf, with a few layers of unconnected stone in
the basement tiers, seemed to constitute one continuous hillock, sloping
upwards from foundation to ridge, like one of the lesser moraines of
Agassiz, save where the fabric here and there bellied outwards or inwards,
in perilous dilapidation, that seemed but awaiting the first breeze.
The low chinky door opened direct into the one wretched apartment of the
hovel, which we found lighted chiefly by holes in the roof. The back
of the sick woman's bed was so placed at the edge of the opening, that it
had formed at one time a sort of partition to the portion of the
apartment, some five or six feet square, which contained the fire-place;
but the boarding that had rendered it such had long since fallen away, and
it now presented merely a naked rickety frame to the current of cold air
from without. Within a foot of the bed-ridden woman's head there was
a hole in the turf-wall, which was, we saw, usually stuffed with a bundle
of rags, but which lay open as we entered, and which furnished a downward
peep of sea and shore, and the rocky Eilan Chasteil, with the
minister's yacht riding in the channel hard by. The little hole in
the wall had formed the poor creature's only communication with the face
of the external world for ten weary years. She lay under a dingy
coverlet, which, whatever its original hue, had come to differ nothing in
colour from the graveyard earth, which must so soon better supply its
place. What perhaps first struck the eye was the strange flatness of
the bed-clothes, considering that a human body lay below: there seemed
scarce bulk enough under them for a human skeleton. The light of the
opening fell on the corpse-like features of the woman, —sallow, sharp,
bearing at once the stamp of disease and of famine; and yet it was
evident, notwithstanding, that they had once been agreeable,—not unlike
those of her daughter, a good-looking girl of eighteen, who, when we
entered, was sitting beside the fire. Neither mother nor daughter
had any English; but it was not difficult to determine, from the welcome
with which the minister was greeted from the sick-bed, feeble as the tones
were, that he was no unfrequent visitor. He prayed beside the poor
creature, and, on coming away, slipped something into her hand. I
learned that not during the ten years in which she had been bed-ridden had
she received a single farthing from the proprietor, nor, indeed, had any
of the poor of the island, and that the parish had no session-funds.
I saw her husband a few days after,—an old worn-out man, with famine
written legibly in his hollow cheek and eye, and on the shrivelled frame,
that seemed lost in his tattered dress; and he reiterated the same sad
story. They had no means of living, he said, save through the
charity of their poor neighbours, who had so little to spare; for the
parish or the proprietor had never given them anything. He had once,
he added, two fine boys, both sailors, who had helped them; but the one
had perished in a storm off the Mull of Cantyre, and the other had died of
fever when on a West India voyage; and though their poor girl was very
dutiful, and staid in their crazy hut to take care of them in their
helpless old age, what other could she do in a place like Eigg than just
share with them their sufferings? It has been recently decided by
the British Parliament, that in cases of this kind the starving poor shall
not be permitted to enter the law courts of the country, there to sue for
a pittance to support life, until an intermediate newly-erected court,
alien to the Constitution, before which they must plead at their own
expense, shall have first given them permission to prosecute their claims.
And I doubt not that many of the English gentlemen whose votes swelled the
majority, and made it such, are really humane men, friendly to an
equal-handed justice, and who hold it to be the peculiar glory of the
Constitution, as well shown by De Lolme, that it has not one statute-book
for the poor, and another for the rich, but the same law and the same
administration of law for all. They surely could not have seen that
the principle of their Poor Law Act for Scotland sets the pauper beyond
the pale of the Constitution in the first instance, that he may be starved
in the second. The suffering paupers of this miserable island
cottage would have all their wants fully satisfied in the grave, long ere
they could establish at their own expense, at Edinburgh, their claim to
enter a court of law. I know not a fitter case for the interposition
of our lately formed "Scottish Association for the Protection of the Poor"
than that of this miserable family; and it is but one of many which the
island of Eigg will be found to furnish.
After a week's weary waiting, settled weather came at last;
and the morning of Tuesday rose bright and fair. My friend, whose
absence at the General Assembly had accumulated a considerable amount of
ministerial labour on his hands, had to employ the day professionally; and
as John Stewart was still engaged with his potato crop, I was necessitated
to sally out on my first geological excursion alone. In passing
vessel-wards, on the previous year, from the Ru Stoir to the
farmhouse of Keill, along the escarpment under the cliffs, I had examined
the shores somewhat too cursorily during the one half of my journey, and
the closing evening had prevented me from exploring them during the other
half at all; and I now set myself leisurely to retrace the way backwards
from the farm-house to the Stoir. I descended to the bottom
of the cliffs, along the pathway which runs between Keill and the solitary
midway shieling formerly described, and found that the basaltic columns
over head, which had seemed so picturesque in the twilight, lost none of
their beauty when viewed by day. They occur in forms the most
beautiful and fantastic; here grouped beside some blind opening in the
precipice, like pillars cut round the opening of a tomb, on some
rock-front in Petræa; there running in
long colonnades, or rising into tall porticoes; yonder radiating in
straight lines from some common centre, resembling huge pieces of
fan-work, or bending out in bold curves over some shaded chasm, like rows
of crooked oaks projecting from the steep sides of some dark ravine.
The various beds of which the cliffs are composed, as courses of ashlar
compose a wall, are of very different degrees of solidity: some are of
hard porphyritic or basaltic trap; some of soft Oolitic sandstone or
shale. Where the columns rest on a soft stratum, their foundations
have in many places given way, and whole porticoes and colonnades hang
perilously forward in tottering ruin, separated from the living rock
behind by deep chasms. I saw one of these chasms, some five or six
feet in width, and many yards in length, that descended to a depth which
the eye could not penetrate; and another partially filled up with earth
and stones, through which, along a dark opening not much larger than a
chimney-vent, the boys of the island find a long descending passage to the
foot of the precipice, and emerge into light on the edge of the grassy
talus half-way down the hill. It reminded me of the tunnel in the
rock through which Imlac opened up a way of escape to Rasselas from the
happy valley,—the "subterranean passage," begun "where the summit hung
over the middle part," and that "issued out behind the prominence."

Avicula |
Mytilus |
From the commencement of the range of cliffs, on half-way to
the shieling, I found the shore so thickly covered up by masses of trap,
the debris of the precipices above, that I could scarce determine the
nature of the bottom on which they rested. I now, however, reached a
part of the beach where the Oolitic beds are laid bare in thin
party-coloured strata, and at once found something to engage me.
Organisms in vast abundance, chiefly shells and fragmentary portions of
fishes, lie closely packed in their folds. One limestone bed,
occurring in a dark shale, seems almost entirely composed of a species of
small oyster; and some two or three other thin beds, of what appears to be
either a species of small Mytilus or Avicula, mixed up with a few shells
resembling large Paludina, and a few more of the gaper family, so closely
resembling existing species, that John Stewart and Alister at once
challenged them as smurslin, the Hebridean name for a well-known
shell in these parts,—the Mya truncata. The remains of
fishes,—chiefly Ganoid scales and the teeth of Placoids,—lie scattered
among the shells in amazing abundance. On the surface of a single
fragment, about nine inches by five, which I detached from one of the
beds, and which now lies before me, I reckon no fewer than twenty-five
teeth, and twenty-two on the area of another. They are of very
various forms,—some of them squat and round, like ill-formed small
shot,—others spiky and sharp, not unlike flooring nails,—some straight as
needles, some bent like the beak of a hawk, some, like the palatal teeth
of the Acrodus of the Lias, resemble small leeches; some, bearing a series
of points ranged on a common base, like masts on the hull of a vessel, the
tallest in the centre, belong to the genus Hybodus. There is a
palpable approximation in the teeth of the leech-like form to the teeth
with the numerous points. Some of the specimens show the same
plicated structure common to both; and on some of the leech backs, if I
may so speak, there are protuberant knobs, that indicate the places of the
spiky points on the hybodent teeth. I have got three of each kind
slit up by Mr George Sanderson, and the internal structure appears to be
the same. A dense body of bone is traversed by what seem innumerable
roots, resembling those of woody shrubs laid bare along the sides of some
forest stream. Each internal opening sends off on every side its
myriads of close-laid filaments; and nowhere do they lie so thickly as in
the line of the enamel, forming, from the regularity with which they are
arranged, a sort of framing to the whole section. It is probable that the
Hybodus,—a genus of shark which became extinct some time about the
beginning of the chalk,—united, like the shark of Port Jackson, a crushing
apparatus of palatal teeth to its lines of cutting ones. Among the
other remains of these beds I found a dense fragment of bone, apparently
reptilian, and a curious dermal plate punctulated with thickset
depressions, bounded on one side by a smooth band, and altogether closely
resembling some saddler's thimble that had been cut open and straightened.
Following the beds downwards along the beach, I found that
one of the lowest which the tide permitted me to examine,—a bed coloured
with a tinge of red,—was formed of a denser limestone than any of the
others, and composed chiefly of vast numbers of small univalves resembling
Neritæ. It was in exactly such a
rock I had found, in the previous year, the reptile remains; and I now set
myself with no little eagerness to examine it. One of the first
pieces I tore up contained a well-preserved Plesiosaurian vertebra; a
second contained a vertebra and a rib; and, shortly after, I disinterred a
large portion of a pelvis. I had at length found, beyond doubt, the
reptile remains in situ. The bed in which they occur is laid
bare here for several hundred feet along the beach, jutting out at a low
angle among boulders and gravel, and the reptile remains we find embedded
chiefly in its under side. It lies low in the Oolite. All the
stratified rocks of the island, with the exception of a small Liasic
patch, belong to the Lower Oolite, and the reptile-bed occurs deep in the
base of the system,—low in its relation to the nether division, in which
it is included. I found it nowhere rising to the level of high-water
mark. It forms one of the foundation tiers of the island, which, as
the latter rises over the sea in some places to the height of about
fourteen hundred feet, its upper peaks and ridges must overlie the bones,
making allowance for the dip, to the depth of at least sixteen hundred.
Even at the close of the Oolitic period this sepulchral stratum must have
been a profoundly ancient one. In working it out, I found two fine
specimens of fish jaws, still retaining their ranges of teeth,—ichtbyodorulites,—occipital
plates of various forms, either reptile or ichthyic,—Ganoid scales, of
nearly the same varieties of pattern as those in the Weald of
Morayshire,—and the vertebræ and ribs,
with the digital, pelvic, and limb-bones, of saurians. It is not
unworthy of remark, that in none of the beds of this deposit did I find
any of the more characteristic shells of the system,—Ammonites,
Belemnites, Gryphites, or Nautili.
I explored the shores of the island on to the Ru Stoir,
and thence to the Bay of Laig; but though I found detached masses of the
reptile bed occurring in abundance, indicating that its place lay not far
beyond the fall of ebb, in no other locality save the one described did I
find it laid bare. I spent some time beside the Bay of Laig in
re-examining the musical sand, in the hope of determining the
peculiarities on which its sonorous qualities depended. But I
examined and cross-examined it in vain. I merely succeeded in
ascertaining, in addition to my previous observations, that the loudest
sounds are elicited by drawing the hand slowly through the incoherent
mass, in a segment of a circle, at the full stretch of the arm, and that
the vibrations which produce them communicate a peculiar titillating
sensation to the hand or foot by which they are elicited, extending in the
foot to the knee, and in the hand to the elbow. When we pass the wet
finger along the edge of an ale-glass partially filled with water, we see
the vibrations thickly wrinkling the surface: the undulations which,
communicated to the air, produce sound, render themselves, when
communicated to the water, visible to the eye; and the titillating feeling
seems but a modification of the same phenomenon acting on the nerves and
fluids of the leg or arm. It appears to be produced by the
wrinklings of the vibrations, if I may so speak, passing along sentient
channels. The sounds will ultimately be found dependent, I am of
opinion, though I cannot yet explain the principle, on the purely
quartzose character of the sand, and the friction of the incoherent upper
strata against under strata coherent and damp. I remained ten days
in the island, and went over all my former ground, but succeeded in making
no further discoveries.
On the morning of Wednesday, June 25th, we set sail for Isle
Ornsay, with a smart breeze from the north-west. The lower and upper
sky was tolerably clear, and the sun looked cheerily down on the deep blue
of the sea; but along the higher ridges of the land there lay long level
strata of what the meteorologists distinguish as parasitic clouds.
When every other patch of vapour in the landscape was in motion, scudding
shorewards from the Atlantic before the still-increasing gale, there
rested along both the Scuir of Eigg and the tall opposite ridge of the
island, and along the steep peaks of Rum, clouds that seemed as if
anchored, each on its own mountain-summit, and over which the gale failed
to exert any propelling power. They were stationary in the middle of
the rushing current, when all else was speeding before it. It has
been shown that these parasitic clouds are mere local condensations of
strata of damp air passing along the mountain summits, and rendered
visible but to the extent in which the summits affect the temperature.
Instead of being stationary, they are ever-forming and ever-dissipating
cloud,—clouds that form a few yards in advance of the condensing hill, and
that dissipate a few yards after they have quitted it. I had nothing
to do on deck, for we had been joined at Eigg by John Stewart; and so,
after watching the appearance of the stationary clouds for some little
time, I went below, and, throwing myself into the minister's large chair,
took up a book. The gale meanwhile freshened, and freshened yet
more; and the Betsey leaned over till her lee chain-plate lay along in the
water. There was the usual combination of sounds beneath and around
me,—the mixture of guggle, clunk, and splash,—of low, continuous rush, and
bluff, loud blow, which forms in such circumstances the voyager's concert.
I soon became aware, however, of yet another species of sound, which I did
not like half so well,—a sound as of the washing of a shallow current over
a rough surface; and, on the minister coming below, I asked him, tolerably
well prepared for his answer, what it might mean. "It means," he
said, "that we have sprung a leak, and a rather bad one; but we are only
some six or eight miles from the Point of Sleat, and must soon catch the
land." He returned on deck, and I resumed my book. Presently,
however, the rush became greatly louder; some other weak patch in the
Betsey's upper works had given way, and anon the water came washing up
from the lee side along the edge of the cabin floor. I got upon deck
to see how matters stood with us; and the minister, easing off the vessel
for a few points, gave instant orders to shorten sail, in the hope of
getting her upper works out of the water, and then to unship the companion
ladder, beneath which a hatch communicated with the low strip of hold
under the cabin, and to bring aft the pails. We lowered our
foresail; furled up the mainsail half-mast high; John Stewart took his
station at the pump; old Alister and I, furnished with pails, took ours,
the one at the foot, the other at the head, of the companion, to hand up
and throw over; a young girl, a passenger from Eigg to the mainland, lent
her assistance, and got wofully drenched in the work; while the minister,
retaining his station at the helm, steered right on. But the gale
had so increased, that, notwithstanding our diminished breadth of sail,
the Betsey, straining hard in the rough sea, still lay in to the gunwale;
and the water, pouring in through a hundred opening chinks in her upper
works, rose, despite of our exertions, high over plank, and beam, and
cabin floor, and went dashing against beds and lockers. She was
evidently filling, and bade fair to terminate all her voyagings by a short
trip to the bottom. Old Alister, a seaman of thirty years' standing,
whose station at the bottom of the cabin stairs enabled him to see how
fast the water was gaining on the Betsey, but not how the Betsey was
gaining on the land, was by no means the least anxious among us.
Twenty years previous he had seen a vessel go down in exactly similar
circumstances, and in nearly the same place; and the reminiscence, in the
circumstances, seemed rather an uncomfortable one. It had been a bad
evening, he said, and the vessel he sailed in, and a sloop, her companion,
were pressing hard to gain the land. The sloop had sprung a leak,
and was straining, as if for life and death, under a press of canvass.
He saw her outsail the vessel to which he belonged, but, when a few
bow-shots a-head, she gave a sudden lurch, and disappeared from the
surface instantaneously, as a vanishing spectre, and neither sloop nor
crew were ever more heard of.
There are, I am convinced, few deaths less painful than some
of those untimely and violent ones at which we are most disposed to
shudder. We wrought so hard at pail and pump,—the occasion, too, was
one of so much excitement, and tended so thoroughly to awaken our
energies,—that I was conscious, during the whole time, of an exhilaration
of spirits rather pleasurable than otherwise. My fancy was active,
and active, strange as the fact may seem, chiefly with ludicrous objects.
Sailors tell regarding the flying Dutchman, that he was a hard-headed
captain of Amsterdam, who, in a bad night and head wind, when all the
other vessels of his fleet were falling back on the port they had recently
quitted, obstinately swore that, rather than follow their example, he
would keep beating about till the day of judgment. And the Dutch
captain, says the story, was just taken at his word, and is beating about
still. When matters were at the worst with us, we got under the lee
of the point of Sleat. The promontory interposed between us and the
roll of the sea; the wind gradually took off; and after having seen the
water gaining fast and steadily on us for considerably more than an hour,
we, in turn, began to gain on the water. It came ebbing out of
drawers and beds, and sunk downwards along pannels and table-legs,—a
second retiring deluge; and we entered Isle Ornsay with the cabin-floor
all visible, and less than two feet water in the hold. On the
following morning, taking leave of my friend the minister, I set off, on
my return homewards, by the Skye steamer, and reached Edinburgh on the
evening of Saturday.

RAMBLES OF A GEOLOGIST;
OR,
TEN THOUSAND MILES OVER THE FOSSILIFEROUS
DEPOSITS OF SCOTLAND. [1]
CHAPTER I.
FROM circumstances that in no way call for
explanation, my usual exploratory ramble was thrown this year (1847) from
the middle of July into the middle of September; and I embarked at Granton
for the north just as the night began to count hour against hour with the
day. The weather was fine, and the voyage pleasant. I saw by
the way, however, at least one melancholy memorial of a hurricane which
had swept the eastern coasts of the island about a fortnight before, and
filled the provincial newspapers with paragraphs of disaster. Nearly
opposite where the Red Head lifts its mural front of Old Red Sandstone a
hundred yards over the beach, the steamer passed a foundered vessel, lying
about a mile and a half off the land, with but her topmast and the point
of her peak over the surface. Her vane, still at the mast-head, was
drooping in the calm; and its shadow, with that of the fresh-coloured spar
to which it was attached, white atop and yellow beneath, formed a
well-defined undulatory strip on the water, that seemed as if ever in the
process of being rolled up, and yet still retained its length unshortened.
Every recession of the swell showed a patch of mainsail attached to the
peak: the sail had been hoisted to its full stretch when the vessel went
down. And thus, though no one survived to tell the story of her
disaster, enough remained to show that she had sprung a leak when
straining in the gale, and that, when staggering under a press of canvass
towards the still distant shore, where, by stranding her, the crew had
hoped to save at least their lives, she had disappeared with a sudden
lurch, and all aboard had perished. I remembered having read, among
other memorabilia of the hurricane, without greatly thinking of the
matter, that "a large sloop had foundered off the Red Head, name unknown."
But the minute portion of the wreck which I saw rising over the surface,
to certify, like some frail memorial in a churchyard, that the dead lay
beneath, had an eloquence in it which the words wanted, and at once sent
the imagination back to deal with the stern realities of the disaster, and
the feelings abroad to expatiate over saddened hearths and melancholy
homesteads, where for many a long day the hapless perished would be missed
and mourned, but where the true story of their fate, though too surely
guessed at, would never be known.
The harvest had been early; and on to the village of
Stonehaven, and a mile or two beyond, where the fossiliferous deposits end
and the primary begin, the country presented from the deck only a wide
expanse of stubble. Every farm-steading we passed had its piled
stack-yard; and the fields were bare. But the line of demarcation
between the Old Red Sandstone and the granitic districts formed also a
separating line between an earlier and later harvest; the fields of the
less kindly subsoil derived from the primary rocks were, I could see,
still speckled with sheaves; and, where the land lay high, or the exposure
was unfavourable, there were reapers at work. All along in the
course of my journey northward from Aberdeen I continued to find the
country covered with shocks, and labourers employed among them; until,
crossing the Spey I entered on the fossiliferous districts of Moray; and
then, as in the south, the champaign again showed a bare breadth of
stubble, with here and there a ploughman engaged in turning it down.
The traveller bids farewell at Stonehaven to not only the Old Red
Sandstone and the early-harvest districts, but also to the rich
wheat-lands of the country, and does not again fairly enter upon them
until, after travelling nearly a hundred miles, he passes from Banffshire
into the province of Moray. He leaves behind him at the same line
the wheat-fields and the cottages built of red stone, to find only barley
and oats, and here and there a plot of rye, associated with cottages of
granite and gneiss, hyperstene and mica schist; but on crossing the Spey,
the red cottages re-appear, and fields of rich wheat-land spread out
around them, as in the south. The circumstance is not unworthy the
notice of the geologist. It is but a tedious process through which
the minute lichen, settling on a surface of naked stone, forms in the
course of ages a soil for plants of greater bulk and a higher order; and
had Scotland been left to the exclusive operation of this slow agent, it
would be still a rocky desert, with perhaps here and there a strip of
alluvial meadow by the side of a stream, and here and there an insulated
patch of rich soil among the hollows of the crags. It might possess
a few gardens for the spade, but no fields for the plough. We owe
our arable land to that comparatively modern geologic agent, whatever its
character, that crushed, as in a mill, the upper parts of the
surface-rocks of the kingdom, and then overlaid them with their own debris
and rubbish to the depth of from one to forty yards. This debris,
existing in one locality as a boulder-clay more or less finely comminuted,
in another as a grossly pounded gravel, forms, with few exceptions, that
subsoil of the country on which the existing vegetation first found root;
and, being composed mainly of the formations on which it more immediately
rests, it partakes of their character, bearing a comparatively lean and
hungry aspect over the primary rocks, and a greatly more fertile one over
those deposits in which the organic matters of earlier creations lie
diffused. Saxon industry has done much for the primary districts of
Aberdeen and Banff-shires, though it has failed to neutralize altogether
the effects of causes which date as early as the times of the Old Red
Sandstone; but in the Highlands, which belong almost exclusively to the
non-fossiliferous formations, and which were, on at least the western
coasts, but imperfectly subjected to that grinding process to which we owe
our sub-soils, the poor Celt has permitted the consequences of the
original difference to exhibit themselves in full. If we except the
islands of the Inner Hebrides, the famine of 1846 was restricted in
Scotland to the primary districts.
I made it my first business, on landing in Aberdeen, to wait
on my friend Mr Longmuir, that I might compare with him a few geological
notes, and benefit by his knowledge of the surrounding country. I
was, however, unlucky enough to find that he had gone, a few days before,
on a journey, from which he had not yet returned; but, through the
kindness of Mrs Longmuir, to whom I took the liberty of introducing
myself, I was made free of his stone-room, and held half an hour's
conversation with his Scotch fossils of the Chalk. These had been
found, as the readers of the Witness must remember from his
interesting paper on the subject, on the hill of Dudwick, in the
neighbourhood of Ellon, and were chiefly impressions—some of them of
singular distinctness and beauty—in yellow flint. I saw among them
several specimens of the Inoceramus, a thin-shelled, ponderously-hinged
conchifer, characteristic of the Cretaceous group, but which has no living
representative; with numerous flints, traversed by rough-edged, bifurcated
hollows, in which branched sponges had once lain; a well-preserved Pecten;
the impressions of spines of Echini of at least two distinct species; and
the nicely-marked impression of part of a Cidaris, with the balls on which
the sockets of the club-like spines had been fitted existing in the print
as spherical moulds, in which shot might be cast, and with the central
ligamentary depression, which in the actual fossil exists but as a minute
cavity, projecting into the centre of each hollow sphere, like the wooden
fusee into the centre of a bomb-shell. This latter cast, fine and
sharp as that of a medal taken in sulphur, seems sufficient of itself to
establish two distinct points: in the first place, that the siliceous
matter of which the flint is composed, though now so hard and rigid, must,
in its original condition, have been as impressible as wax softened to
receive the stamp of the seal; and, in the next, that though it was thus
yielding in its character, it could not have greatly shrunk in the process
of hardening. I looked with no little interest on these remains of a
Scotch formation now so entirely broken up, that, like those ruined cities
of the East which exist but as mere lines of wrought material barring the
face of the desert, there has not "been left one stone of it upon
another;" but of which the fragments, though widely scattered, bear
imprinted upon them, like the stamped bricks of Babylon, the story of its
original condition, and a record of its founders. All Mr
Longmuir's Cretaceous fossils from the hill of Dudwick are of flint,—a
substance not easily ground down by the denuding agencies.
I found several other curious fossils in Mr Longmuir's
collection. Greatly more interesting, however, than any of the
specimens which it contains, is the general fact, that it should be the
collection of a Free Church minister, sedulously attentive to the proper
duties of his office, but who has yet found time enough to render himself
an accomplished geologist; and whose week-day lectures on the science
attract crowds, who receive from them, in many instances, their first
knowledge of the strange revolutions of which our globe has been the
subject, blent with the teachings of a wholesome theology. The
present age, above all that has gone before, is peculiarly the age of
physical science; and of all the physical sciences, not excepting
astronomy itself, geology, though it be a fact worthy of notice, that not
one of our truly accomplished geologists is an infidel, is the science of
which infidelity has most largely availed itself. And as the
theologian in a metaphysical age,—when scepticism, conforming to the
character of the time, disseminated its doctrines in the form of nicely
abstract speculations,—had, in order that the enemy might be met in his
own field, to become a skilful metaphysician, he must now, in like manner,
address himself to the tangibilities of natural history and geology, if he
would avoid the danger and disgrace of having his flank turned by every
sciolist in these walks whom he may chance to encounter. It is those
identical bastions and outworks that are now attacked, which must be
now defended; not those which were attacked some eighty or a hundred
years ago. And as he who succeeds in first mixing up fresh and
curious truths, either with the objections by which religion is assailed
or the arguments by which it is defended, imparts to his cause all the
interest which naturally attaches to these truths, and leaves to his
opponent, who passes over them after him as at second hand, a subject
divested of the fire-edge of novelty, I can deem Mr Longmuir well and not
unprofessionally employed, in connecting with a sound creed the
picturesque marvels of one of the most popular of the sciences, and by
this means introducing them to his people, linked, from the first, with
right associations. According to the old fiction, the look of the
basilisk did not kill unless the creature saw before it was seen;—its mere
return glance was harmless: and there is a class of thoroughly
dangerous writers who in this respect resemble the basilisk. It is
perilous to give them a first look of the public. They are
formidable simply as the earliest popularizers of some interesting
science, or the first promulgators of some class of curious little-known
facts, with which they mix up their special contributions of error,—often
the only portion of their writings that really belongs to themselves.
Nor is it at all so easy to counteract as to confute them.
A masterly confutation of the part of their works truly their own may,
from its subject, be a very unreadable book: it can have but the
insinuated poison to deal with, unmixed with the palatable pabulum in
which the poison has been conveyed; and mere treatises on poisons, whether
moral or medical, are rarely works of a very delectable order. It
seems to be on this principle that there exists no confutation of the
"Constitution of Man" in which the ordinary reader finds amusement enough
to carry him through; whereas the work itself, full of curious
miscellaneous information, is eminently readable; and that the "Vestiges
of Creation,"—a treatise as entertaining as the "Arabian Nights,"—bids
fair, not from the amount of error which it contains, but from the amount
of fresh and interestingly-told truth with which the error is mingled, to
live and do mischief when the various solidly-scientific replies which it
has called forth are laid upon the shelf. Both the "Constitution"
and the "Vestiges" had the advantage, so essential to the basilisk, of
taking the first glance of the public on their respective subjects;
whereas their confutators have been able to render them back but mere
return glances. The only efficiently counteractive mode of
looking down the danger, in cases of this kind, is the mode adopted by Mr
Longmuir.
There was a smart frost next morning; and, for the first few
hours, my seat on the top of the Banff coach, by which I travelled across
the country to where the Gamrie and Banff roads part company, was
considerably more cool than agreeable. But the keen morning improved
into a brilliant day, with an atmosphere transparent as if there had been
no atmosphere at all, through which the distant objects looked out; sharp
of outline, and in as well-defined light and shadow, as if they had
occupied the background, not of a Scotch, but of an Italian landscape.
A few speck-like sails, far away on the intensely blue sea, which opened
upon us in a stretch of many leagues, as we surmounted the moory ridge
over Macduff, gleamed to the sun with a radiance bright as that of the
sparks of a furnace blown to a white heat. The land, uneven of
surface, and open, and abutting in bold promontories on the frith, still
bore the sunny hue of harvest, and seemed as if stippled over with shocks
from the ridgy hill summits, to where ranges of giddy cliffs flung their
shadows across the beach. I struck off for Gamrie by a path that
runs eastward, nearly parallel to the shore,—which at one or two points it
overlooks from dark-coloured cliffs of grauwacke slate,—to the fishing
village of Gardenstone. My dress was the usual fatigue suit of
russet, in which I find I can work amid the soil of ravines and quarries
with not only the best effect, but with even the least possible sacrifice
of appearance: the shabbiest of all suits is a good suit spoiled. My
hammer-shaft projected from my pocket; a knapsack, with a few changes of
linen, slung suspended from my shoulders; a strong cotton umbrella
occupied my better band; and a gray maud, buckled shepherd-fashion aslant
the chest, completed my equipment. There were few travellers on the
road, which forked off on the hill-side a short mile away, into two
branches, like a huge letter Y, leaving me uncertain which branch to
choose; and I made up my mind to have the point settled by a woman of
middle age, marked by a hard, manly countenance, who was coming up towards
me, bound apparently for the Banff or Macduff market, and stooping under a
load of dairy produce. She too, apparently, had her purpose to serve
or point to settle; for as we met, she was the first to stand; and,
sharply scanning my appearance and aspect at a glance, she abruptly
addressed me. "Honest man," she said, "do you see yon house wi' the
chimla?" "That house with the farm-steadings and stacks beside it?"
I replied. "Yes." "Then I'd be obleeged if ye wald just stap
in as ye'r gaing east the gate, and tell our folk that the stirk has gat
fra her tether, an' 'ill brak on the wat clover. Tell them to sen'
for her that minute." I undertook the commission; and, passing the
endangered stirk, that seemed luxuriating, undisturbed by any presentiment
of impending peril, amid the rich swathe of a late clover crop, still damp
with the dews of the morning frost, I tapped at the door of the
farm-house, and delivered my message to a young good-looking girl, in
nearly the words of the woman: "The gudewife bade me tell them," I said,
"to send that instant for the stirk, for she had gat fra her tether, and
would brak on the wat clover." The girl blushed just a very little,
and thanked me; and then, after obliging me, in turn, by laying down for
me my proper route,—for I had left the question of the forked road to be
determined at the farm-house,—she set off at high speed, to rescue the
unconscious stirk. A walk of rather less than two hours brought me
abreast of the Bay of Gamrie,—a picturesque indentation of the coast, in
the formation of which the agency of the old denuding forces, operating on
deposits of unequal solidity, may be distinctly traced. The
surrounding country is composed chiefly of Silurian schists, in which
there is deeply inlaid a detached strip of mouldering Old Red Sandstone,
considerably more than twenty miles in length, and that varies from two to
three miles in breadth. It seems to have been let down into the more
ancient formation,—like the keystone of a bridge into the ringstones of
the arch when the work is in the act of being completed,—during some of
those terrible convulsions which cracked and rent the earth's crust, as if
it had been an earthen pipkin brought to a red heat and then plunged into
cold water. Its consequent occurrence in a lower tier of the
geological edifice than that to which it originally belonged has saved it
from the great denudation which has swept from the surface of the
surrounding country the tier composed of its contemporary beds and strata,
and laid bare the grauwacke on which this upper tier rested. But
where it presents its narrow end to the sea, as the older houses in our
more ancient Scottish villages present their gables to the street, the
waves of the German Ocean, by incessantly charging against it, propelled
by the tempests of the stormy north, have hollowed it into the Bay of
Gamrie, and left the more solid grauwacke standing out in bold
promontories on either side, as the headlands of Gamrie and Troup.
In passing downwards on the fishing village of Gardenstone,
mainly in the hope of procuring a guide to the ichthyolite beds, I saw a
labourer at work with a pick-axe, in a little craggy ravine, about a
hundred yards to the left of the path, and two gentlemen standing beside
him. I paused for a moment, to ascertain whether the latter were not
brother workers in the geologic field. "Hilloa!—here,"—shouted out
the stouter of the two gentlemen, as if, by some clairvoyant
faculty, he had dived into my secret thought; "come here." I went
down into the ravine, and found the labourer engaged in disinterring
ichthyolitic nodules out of a bed of gray stratified clay, identical in
its composition with that of the Cromarty fish-beds; and a heap of
freshly-broken nodules, speckled with the organic remains of the Lower Old
Red Sandstone,—chiefly occipital plates and scales,—lay beside him.
"Know you aught of these? said the stouter gentleman, pointing to the
heap. "A little," I replied; "but your specimens are none of the
finest. Here, however, is a dorsal plate of Coccosteus; and here a
scattered group of scales of Osteolepis; and here the occipital plates of
Cheirolepis Cummingiœ; and here the spine of the anterior dorsal of
Diplacanthus Striatus." My reading of the fossils was at once
recognised, like the mystic sign of the freemason, as establishing for me
a place among the geologic brotherhood; and the stout gentleman producing
a spirit-flask and a glass, I pledged him and his companion in a bumper.
"Was I not sure?" he said, addressing his friend: "I knew by the cut of
his jib, notwithstanding his shepherd's plaid, that he was a wanderer of
the scientific cast." We discussed the peculiarities of the deposit,
which, in its mineralogical character, and generically in that of its
organic contents, resembles, I found, the fish-beds of Cromarty (though,
curiously enough, the intervening contemporary deposits of Moray and the
western parts of Banffshire differ widely, in at least their chemistry,
from both); and we were right good friends ere we parted. To men who
travel for amusement, incident is incident, however trivial in itself, and
always worth something. I showed the younger of the two geologists
my mode of breaking open an ichthyolitic nodule, so as to secure the best
possible section of the fish. "Ah," he said, as he marked a style of
handling the hammer which, save for the fifteen years' previous practice
of the operative mason, would be perhaps less complete,—"Ah, you must have
broken open a great many." His own knowledge of the formation and
its ichthyolites had been chiefly derived, he added, from a certain little
treatise on the "Old Red Sandstone," rather popular than scientific, which
he named. I of course claimed no acquaintance with the work; and the
conversation went on. The ill luck of my new friends, who had been
toiling among the nodules for hours without finding an ichthyolite worth
transferring to their bag, showed me that, without excavating more deeply
than my time allowed, I had no chance of finding good specimens.
But, well content to have ascertained that the ichthyolite bed of Gamrie
is identical in its Composition, and, generically at least, in its
organisms, with the beds with which I was best acquainted, I rose to come
away. The object which I next proposed to myself was, to determine
whether, as at Eathie and Cromarty, the fossils here appear not only on
the hill-side, but also crop out along the shore. On taking leave,
however, of the geologists, I was reminded by the younger of what I might
have otherwise forgotten,—a raised beach in the immediate neighbourhood
(first described by Mr Prestwich, in his paper on the Gamrie
ichthyolites), which contains shells of the existing species at a higher
level than elsewhere,—so far as is yet known,—on the east coast of
Scotland. And, kindly conducting me till he had brought me full
within view of it, we parted. The ichthyolites which I had just been
laying open occur on the verge of that Strathbogie district in which the
Church controversy raged so hot and high; and by a common enough trick of
the associative faculty, they now recalled to my mind a stanza which
memory had somehow caught when the battle was at the fiercest. It
formed part of a satiric address, published in an Aberdeen newspaper, to
the not very respectable non-intrusionists who had smoked tobacco and
drank whisky in the parish church at Culsalmond, on the day of a certain
forced settlement there, specially recorded by the clerks of the
Justiciary Court.
Tobacco and whisky cost siller,
And meal is but scanty at hame;
But gang to the stace-mason M——r,
Wi' Old Red Sandstone fish he'll fill your wame. |
Rather a dislocated line that last, I thought, and too much in the style
in which Zachary Boyd sings "Pharaoh and the Pascal." And as it is
wrong to leave the beast of even an enemy in the ditch, however long its
ears, I must just try and set it on its legs. Would it not run
better thus?
"Tobacco and whisky cost siller,
An' meal is but scanty at hame;
But gang to the stane-mason M——r,"
He'll pang wi' ichth'ólites your wame,—
Wi' fish! ! as Agassiz has ca'd'em,
In Greek, like themsel's, hard an' odd,
That were baked in stane pies afore Adam
Gaed names to the haddocks and cod. |
Bad enough as rhyme, I suspect; but conclusive as evidence to prove that
the animal spirits, under the influence of the bracing walk, the fine day,
and the agreeable rencounter at the fish-beds,—not forgetting the
half-gill bumper,—had mounted very considerably above their ordinary level
at the editorial desk.
The raised beach may be found on the slopes of a
grass-covered eminence, once the site of an ancient hill-fort, and which
still exhibits, along the rim-like edge of the flat area atop, scattered
fragments of the vitrified walls. A general covering of turf
restricted my examination of the shells to one point, where a landslip on
a small scale had laid the deposit bare; but I at least saw enough to
convince me that the debris of the shell-fish used of old as food by the
garrison had not been mistaken for the remains of a raised beach,—a
mistake which in other localities has occurred, I have reason to believe,
oftener than once. The shells, some of them exceedingly minute, and
not of edible species, occur in layers in a siliceous stratified sand,
overlaid by a bed of bluish-coloured silt. I picked out of the sand
two entire specimens of a full-grown Fusus, little more than half an inch
in length, —the Fusus turricola; and the greater number of the
fragments that lay bleaching at the foot of the broken slope in a state of
chalky friability, seemed to be fragments of those smaller bivalves,
belonging to the genera Donax, Venus, and Mactra, that are
so common on flat sandy shores. But when the sea washed over these
shells, they could have been the denizens of at least no flat
shore. The descent on which they occur sinks downwards to the
existing beach, over which, it is elevated at this point two hundred and
thirty feet, at an angle with the horizon of from thirty-five to forty
degrees. Were the land to be now submerged to where they appear on
the hill-side, the bay of Gamrie, as abrupt in its slopes as the upper
part of Loch Lomond or the sides of Loch Ness, would possess a depth of
forty fathoms water at little more than a hundred yards from the shore.
I may add, that I could trace at this height no marks of such a continuous
terrace around the sides of the bay as the waves would have infallibly
excavated in the diluvium, had the sea stood at a level so high, or,
according to the more prevalent view, had the land stood at a level so
low, for any considerable time; though the green banks which sweep around
the upper part of the inflection, unscarred by the defacing plough, would
scarce have failed to retain some mark of where the surges had broken, had
the surges been long there. Whatever may in this special case be the
fact, however, I cannot doubt that in the comparatively modern period of
the boulder clays, Scotland lay buried under water to a depth at least
five times as great as the space between this ancient sea-beach and the
existing tide-line.
CHAPTER II.
I LINGERED on the hill-side considerably longer than
I ought; and then, hurrying downwards to the beach, passed eastwards under
a range of abrupt, mouldering precipices of red sandstone, to the village.
From the lie of the strata, which, instead of inclining coastwise, dip
towards the interior of the country, and present in the descent seawards
the outcrop of lower and yet lower deposits of the formation, I found it
would be in vain to look for the ichthyolite beds along the shore.
They may possibly be found, however, though I lacked time to ascertain the
fact, along the sides of a deep ravine, which occurs near an old
ecclesiastical edifice of gray stone, perched, nest-like, half-way up the
bank, on a green hummock that overlooks the sea. The rocks, laid
bare by the tide, belong to the bed of coarse-grained red sandstone,
varying from eighty to a hundred and fifty feet in thickness, which lies
between the lower fish-bed and the great conglomerate, and which, in not a
few of its strata, passes itself into a species of conglomerate, different
only from that which it overlies, in being more finely comminuted.
The continuity of this bed, like that of the deposit on which it rests, is
very remarkable. I have found it occurring at many various points,
over an area at least ten thousand square miles in extent, and bearing
always the same well-marked character of a more thoroughly ground-down
conglomerate than the great conglomerate on which it reposes. The
underlying bed is composed of broken fragments of the rocks below,
crushed, as if by some imperfect rudimentary process, like that which in a
mill merely breaks the grain; whereas, in the bed above, a portion of the
previously-crushed materials seems to have been subjected to some further
attritive process, like that through which, in the mill, the broken grain
is ground down into meal or flour.
As I passed onwards, I saw, amid a heap of drift-weed
stranded high on the beach by the previous tide, a defunct father-lasher,
with the two defensive spines which project from its opercles stuck fast
into little cubes of cork, that had floated its head above water, as the
tyro-swimmer floats himself upon bladders; and my previous acquaintance
with the habits of a fishing village enabled me at once to determine why
and how it had perished. Though almost never used as food on the
eastern coast of Scotland, it had been inconsiderate enough to take the
fisherman's bait, as if it had been worthy of being eaten; and he had
avenged himself for the trouble it had cost him, by mounting it on cork,
and sending it off, to wander between wind and water, like the Flying
Dutchman, until it died. Was there ever on earth a creature save man
that could have played a fellow-mortal a trick at once so ingeniously and
gratuitously cruel? Or what would be the proper inference, were I to
find one of the many-thorned ichthyolites of the Lower Old Red Sandstone
with the spines of its pectorals similarly fixed on cubes of lignite?—that
there had existed in these early ages not merely physical death, but also
moral evil; and that the being who perpetrated the evil could not only
inflict it simply for the sake of the pleasure he found in it, and without
prospect of advantage to himself, but also by so adroitly reversing,
fiend-like, the purposes of the benevolent Designer, that the weapons
given for the defence of a poor harmless creature should be converted into
the instruments of its destruction. It was not without meaning that
it was forbidden by the law of Moses to seethe a kid in its mother's milk.
A steep bulwark in front, against which the tide lashes twice
every twenty-four hours,—an abrupt hill behind,—a few rows of squalid
cottages built of red sandstone, much wasted by the keen sea-winds,—a
wilderness of dunghills and ruinous pig-sties,—women seated at the doors,
employed in baiting lines or mending nets,—groups of men lounging lazily
at some gable-end fronting the sea,—herds of ragged children playing in
the lanes,—such are the components of the fishing village of Gardenstone.
From the identity of name, I had associated the place with that Lord
Gardenstone of the Court of Session who published, late in the last
century, a volume of "Miscellanies in Prose and Verse," containing, among
other clever things, a series of tart criticisms on English plays,
transcribed, it was stated in the preface, from the margins and fly-leaves
of the books of a "small library kept open by his Lordship" for the
amusement of travellers at the inn of some village in his immediate
neighbourhood; and taking it for granted, somehow, that Gardenstone was
the village, I was looking around me for the inn, in the hope that where
his Lordship had opened a library I might find a dinner. But failing
to discern it, I addressed myself on the subject to an elderly man in a
pack-sheet apron, who stood all alone, looking out upon the sea, like
Napoleon; in the print, from a projection of the bulwark. He turned
round, and showed, by an unmistakeable expression of eye and feature, that
he was what the servant girl in "Guy Mannering" characterizes as "very
particularly drunk,"—not stupidly, but happily, funnily, conceitedly
drunk, and full of all manner of high thoughts of himself. "It'll be
an awfu' coorse nicht," he said, "fra the sea." "Very likely," I
replied, reiterating my query in a form that indicated some little
confidence of receiving the needed information; " I daresay you could
point me out the public-house here?" "Aweel I wat, that I can; but
what's that?" pointing to the straps of my knapsack; "are ye a sodger on
the Queen's account, or ye'r ain?" "On my own, to be sure; but have
ye a public-house here?" "Ay, twa; ye'll be a traveller?" "O
yes, great traveller, and very hungry: have I passed the best public
house?" "Ay; and ye'll hae come a gude stap the day?" A woman
came up, with spectacles on nose, and a piece of white seam-work in her
hand; and, cutting short the dialogue by addressing myself to her, she at
once directed me to the public-house. "Hoot, gudewife," I heard the
man say, as I turned down the street, "we suld ha'e gotten mair oot o'
him. He's a great traveller yon, an' has a gude Scots tongue in his
head."
Travellers, save when, during the herring season, an
occasional fish-curer comes the way, rarely bait at the Gardenstone inn;
and in the little low-browed room, with its windows in the thatch, into
which, as her best, the landlady ushered me, I certainly found nothing to
identify the locale with that chosen by the literary lawyer for his open
library. But, according to Ferguson, though "learning was scant,
provision was good;" and I dined sumptuously on an immense platter of
fried flounders. There was a little bit of cold pork added to the
fare; but, aware from previous experience of the pisciverous habits of the
swine of a fishing village, I did what I knew the defunct pig must have
very frequently done before me,—satisfied a keenly-whetted appetite on
fish exclusively. I need hardly remind the reader that Lord
Gardenstone's inn was not that of Gardenstone, but that of Laurencekirk,—the
thriving village which it was the special ambition of this law-lord of the
last century to create; and which, did it produce only its famed snuff
boxes, with the invisible hinges would be rather a more valuable boon to
the country than that secured to it by those law-lords of our own days,
who at one fell blow disestablished the national religion of Scotland, and
broke off the only handle by which their friends the politicians could
hope to manage the country's old vigorous Presbyterianism.
Meanwhile it was becoming apparent that the man with the apron had as
shrewdly anticipated the character of the coming night as if he had been
soberer. The sun, ere its setting, disappeared in a thick leaden
haze, which enveloped the whole heavens; and twilight seemed posting on to
night a full hour before its time. I settled a very moderate bill,
and set off under the cliffs at a round pace, in the hope of scaling the
hill, and gaining the high road atop which leads to Macduff, ere the
darkness closed. I had, however, miscalculated my distance; I,
besides, lost some little time in the opening of the deep ravine to which
I have already referred as that in which possibly the fish-beds may be
found cropping out; and I had got but a little beyond the gray
ecclesiastical ruin, with its lonely burying-ground, when the tempest
broke and the night fell.
One of the last objects which I saw, as I turned to take a
farewell look of the bay of Gamrie, was the magnificent promontory of
Troup Head, outlined in black on a ground of deep gray, with its two
terminal stacks standing apart in the sea. And straightway, through
one of those tricks of association so powerful in raising, as if from the
dead, buried memories of things of which the mind has been oblivious for
years, there started up in recollection the details of an ancient
ghost-story, of which I had not thought before for perhaps a quarter of a
century. It had been touched, I suppose, in its obscure, unnoted
corner, as Ithuriel touched the toad, by the apparition of the insulated
stacks of Troup, seen dimly in the thickening twilight over the solitary
burying-ground. For it so chances that one of the main incidents of
the story bears reference to an insulated sea-stack; and it is connected
altogether, though I cannot fix its special locality, with this part of
the coast. The story had been long in my mother's family, into which
it had been originally brought by a great-grandfather of the writer, who
quitted some of the seaport villages of Banffshire for the northern side
of the Moray Frith, about the year 1718; and, when pushing on in the
darkness, straining, as I best could, to maintain a sorely-tried umbrella
against the capricious struggles of the tempest, that now tatooed
furiously upon its back as if it were a kettle-drum, and now got
underneath its stout ribs, and threatened to send it up aloft like a
balloon, and anon twisted it from side to side, and strove to turn it
inside out like a Kilmarnock nightcap,—I employed myself in arranging in
my mind the details of the narrative, as they had been communicated to me
half an age before by a female relative.
The opening of the story, though it existed long ere the
times of Sir Walter Scott or the Waverley novels, bears some resemblance
to the opening, in the "Monastery," of the story of the White Lady of
Avenel. The wife of a Banffshire proprietor of the minor class had
been about six months dead, when one of her husband's ploughmen, returning
on horseback from the smithy, in the twilight of an autumn evening, was
accosted, on the banks of a small stream, by a stranger lady, tall and
slim, and wholly attired in green, with her face wrapped up in the hood of
her mantle, who requested to be taken up behind him on the horse, and
carried across. There was something in the tones of her voice that
seemed to thrill through his very bones, and to insinuate itself, in the
form of a chill fluid, between his skull and the scalp. The request,
too, appeared a strange one; for the rivulet was small and low, and could
present no serious bar to the progress of the most timid traveller.
But the man, unwilling ungallantly to offend a lady, turned his horse to
the bank, and she sprang up lightly behind him. She was, however, a
personage that could be better seen than felt: she came in contact with
the ploughman's back, he said, as if she had been an ill-filled sack of
wool; and when, on reaching the opposite side of the streamlet, she leaped
down as lightly as she had mounted, and he turned fearfully round to catch
a second glimpse of her, it was in the conviction that she was a creature
considerably less earthly in her texture than himself. She had
opened, with two pale, thin arms, the enveloping hood, exhibiting a face
equally pale and thin, which seemed marked, however, by the roguish,
half-humorous expression of one who had just succeeded in playing off a
good joke. "My dead mistress! !" exclaimed the ploughman.
"Yes, John, your mistress," replied the ghost. "But ride
home, my bonny man, for it's growing late: you and I will be better
acquainted ere long." John accordingly rode home, and told his
story.
Next evening, about the same hour, as two of the laird's
servant-maids were engaged in washing in an out-house, there came a slight
tap to the door. "Come in," said one of the maids; and the lady
entered, dressed, as on the previous night, in green. She swept past
them to the inner part of the washing-room; and, seating herself on a low
bench, from which, ere her death, she used occasionally to superintend
their employment, she began to question them, as if still in the body,
about the progress of their work. The girls, however, were greatly
too frightened to make any reply. She then visited an old woman who
had nursed the laird, and to whom she used to show, ere her departure,
greatly more kindness than her husband. And she now seemed as much
interested in her welfare as ever. She inquired whether the laird
was kind to her; and, looking round her little smoky cottage, regretted
she should be so indifferently lodged, and that her cupboard, which was
rather of the emptiest at the time, should not be more amply furnished.
For nearly a twelvemonth after, scarce a day passed in which she was not
seen by some of the domestics; never, however, except on one occasion,
after the sun had risen, or before it had set. The maids could see
her in the gray of the morning flitting like a shadow round their beds, or
peering in upon them at night through the dark window-panes, or at
half-open doors. In the evening she would glide into the kitchen or
some of the out-houses,—one of the most familiar and least dignified of
her class that ever held intercourse with mankind,—and inquire of the
girls how they had been employed during the day; often, however, without
obtaining an answer, though from a cause different from that which had at
first tied their tongues. For they had become so regardless of her
presence, viewing her simply as a troublesome mistress, who had no longer
any claim to be heeded, that when she entered, and they had dropped their
conversation, under the impression that their visitor was a creature of
flesh and blood like themselves, they would again resume it, remarking
that the entrant was "only the green lady." Though always
cadaverously pale, and miserable looking, she affected a joyous
disposition, and was frequently heard to laugh, even when invisible.
At one time, when provoked by the studied silence of a servant girl, she
flung a pillow at her head, which the girl caught up and returned; at
another, she presented her first acquaintance, the ploughman, with what
seemed to be a handful of silver coin, which he transferred to his pocket,
but which, on hearing her laugh, he drew out, and found to be merely a
handful of slate shivers. On yet another occasion, the man, when
passing on horseback through a clump of wood, was repeatedly struck from
behind the trees by little pellets of turf; and, on riding into the
thicket, he found that his assailant was the green lady. To her
husband she never appeared; but he frequently heard the tones of her voice
echoing from the lower apartments, and the faint peal of her cold,
unnatural laugh.
One day at noon, a year after her first appearance, the old
nurse was surprised to see her enter the cottage; as all her previous
visits had been made early in the morning or late in the evening; whereas
now,—though the day was dark and lowering, and a storm of wind and rain
had just broken out,—still it was day. "Mammie," she said, "I cannot
open the heart of the laird, and I have nothing of my own to give you; but
I think I can do something for you now. Go straight to the White
House [that of a neighbouring proprietor], and tell the folk there to set
out with all the speed of man and horse for the black rock in the sea, at
the foot of the crags, or they'll rue it dearly to their dying day.
Their bairns, foolish things, have gone out to the rock, and the tide has
flowed round them; and, if no help reach them soon, they'll be all
scattered like sea-ware on the shore ere the fall of the sea. But if
you go and tell your story at the White House, mammie, the bairns will be
safe for an hour to come, and there will be something done by their mother
to better you, for the news." The woman went, as directed, and told
her story; and the father of the children set out on horseback in hot
haste for the rock,—a low, insulated skerry, which, lying on a solitary
part of the beach, far below the line of flood, was shut out from the view
of the inhabited country by a wall of precipices, and covered every tide
by several feet of water. On reaching the edge of the cliffs, he saw
the black rock, as the woman had described, surrounded by the sea, and the
children clinging to its higher crags. But, though the waves were
fast rising, his attempts to ride out through the surf to the poor little
things were frustrated by their cries, which so frightened his horse as to
render it unmanageable; and so he had to gallop on to the nearest fishing
village for a boat. So much time was unavoidably lost in
consequence, that nearly the whole beach was covered by the sea, and the
surf had begun to lash the feet of the precipices behind, but until the
boat arrived, not a single wave dashed over the black rock; though
immediately after the last of the children had been rescued, an immense
wreath of foam rose twice a man's height over its topmost pinnacle.
The old nurse, on her return to the cottage, found the green
lady sitting beside the fire. "Mammie," she said, "you have made
friends to yourself to-day, who will be kinder to you than your
foster-son. I must now leave you. My time is out, and you'll
be all left to yourselves; but I'll have no rest, mammie, for many a
twelvemonth to come. Ten years ago, a travelling pedlar broke into
our garden in the fruit season, and I sent out our old ploughman, who is
now in Ireland, to drive him away. It was on a Sunday, and every
body else was in church. The men struggled and fought, and the
pedlar was killed. But though I at first thought of bringing the
case before the laird, when I saw the dead man's pack, with its silks and
its velvets, and this unhappy piece of green satin (shaking her dress), my
foolish heart beguiled me, and I bade the ploughman bury the pedlar's body
under our ash tree, in the corner of our garden, and we divided his goods
and money between us. You must bid the laird raise his bones, and
carry them to the churchyard; and the gold, which you will find in the
little bowl under the tapestry in my room, must be sent to a poor old
widow, the pedlar's mother, who lives on the shore of Leith. I must
now away to Ireland to the ploughman; and I'll be e'en less welcome to
him, mammie, than at the laird's; but the hungry blood cries loud against
us both,—him and me,—and we must suffer together. Take care you look
not after me till I have passed the knowe." She glided away, as she
spoke, in a gleam of light; and when the old woman had withdrawn her hand
from her eyes, dazzled by the sudden brightness, she saw only a large
black grayhound crossing the moor. And the green lady was never
afterwards seen in Scotland. The little hoard of gold pieces,
however, stored in a concealed recess of her former apartment, and the
mouldering remains of the pedlar under the ash tree, gave evidence to the
truth of her narrative. The story was hardly wild enough for a night
so drear and a road so lonely; its ghost-heroine was but a homely
ghost-heroine, too little aware that the same familiarity which, according
to the proverb, breeds contempt when exercised by the denizens of this
world, produces similar effects when too much indulged in by the
inhabitants of another. But the arrangement and restoration of the
details of the tradition,—for they had been scattered in my mind like the
fragments of a broken fossil,—furnished me with so much amusement, when
struggling with the storm, as to shorten by at least one-half the seven
miles which intervene between Gamrie and Macduff. Instead, however,
of pressing on to Ban; as I had at first intended, I baited for the night
at a snug little inn in the latter village, which I reached just wet
enough to enjoy the luxury of a strong clear fire of Newcastle coal.
Mrs Longmuir had furnished me with a note of introduction to
Dr Emslie of Banff, an intelligent geologist, familiar with the deposits
of the district; and, walking on to his place of residence next morning,
in a rain as heavy as that of the previous night, I made it my first
business to wait on him, and deliver the note. Ere, however,
crossing the Deveron, which flows between Banff and Macduff, I paused for
a few minutes in the rain, to mark the peculiar appearance presented by
the beach where the river disembogues into the frith. Occurring as a
rectangular spit in the line of the shore, with the expanded stream
widening into an estuary on its upper side, and the open sea on the lower,
it marks the scene of an obstinate contest between antagonist forces,—the
powerful sweep of the torrent, and the not less powerful waves of the
stormy north-east; and exists, in consequence, as a long gravelly prism,
which presents as steep an angle of descent to the waves on the one side
as to the current on the other. It is a true river bar, beaten in
from its proper place in the sea, by the violence of the surf, and fairly
stranded. Dr Emslie obligingly submitted to my inspection his set of
Gamrie fossils, containing several good specimens of Pterichthys and
Coccosteus, undistinguishable, like those I had seen on the previous day,
in their state of keeping, and the character of the nodular matrices in
which they lie, from my old acquaintance the Cephalaspians of Cromarty.
The animal matter which the bony plates and scales originally contained
has been converted, in both the Gamrie and Cromarty ichthyolites, into a
jet-black bitumen; and in both, the inclosing nodules consist of a
smoke-coloured argillaceous limestone, which formed around the organisms
in a bed of stratified clay, and at once exhibits, in consequence, the
rectilinear lines of the stratification, mechanical in their origin, and
the radiating ones of the sub-crystalline concretion, purely a trick of
the chemistry of the deposit. A Pterichthys in Dr Emslie's
collection struck me as different in its proportions from any I had
previously seen, though, from its state of rather imperfect preservation,
I hesitated to pronounce absolutely upon the fact. I cannot now
doubt, however, that it belonged to a species not figured nor described at
the time; but which, under the name Pterichthys quadratus, forms in
part the subject of a still unpublished memoir, in which Sir Philip
Egerton, our first British authority on fossil fish, has done me the
honour to associate my humble name with his own; and which will have the
effect of reducing to the ranks of the Pterichthyan genus the supposed
genera Pamphractus and Homothorax. A second set of
fossils, which Dr Emslie had derived from his tile-works at Blackpots,
proved, I found, identical with those of the Eathie Lias. As this
Banffshire deposit had formed a subject of considerable discussion and
difference among geologists, I was curious to examine it; and the Doctor,
though the day was still none of the best, kindly walked out with me, to
bring under my notice appearances which, in the haste of a first
examination, I might possibly overlook, and to show me yet another set of
fossils which he kept at the works. He informed me, as we went, that
the Grauwacke (Lower Silurian) deposits of the district, hitherto deemed
so barren, had recently yielded their organisms in a slate quarry at
Gamriehead; and that they belong to that ancient family of the
Pennatularia which, in this northern kingdom, seems to have taken
precedence of all the others. Judging from what now appears, the
Graptolite must be regarded as the first settler who squatted for a living
in that deep-sea area of undefined boundary occupied at the present time
by the bold wave-worn headlands and blue hills of Scotland; and this new
Banffshire locality not only greatly extends the range of the fossil in
reference to the kingdom, but also establishes, in a general way, the
fossiliferous identity of the Lower Silurian deposits to the north of the
Grampians with that of Peebles-shire and Galloway in the south,—so far as
I know, the only other two Scottish districts in which this organism has
been found.
The argillaceous deposit of Blackpots occupies, in the form
of a green swelling bank, a promontory rather soft than bold in its
contour, that projects far into the sea, and forms, when tipped with its
slim column of smoke from the tile-kiln, a pleasing feature in the
landscape. I had set it down on the previous day, when it first
caught my eye from the lofty cliffs of Gamrie-head, at the distance of
some ten or twelve miles, as different in character from all the other
features of the prospect. The country generally is moulded on a
framework of primary rock, and presents headlands of hard, sharp outline,
to the attrition of the waves; whereas this single headland in the
midst,—soft-lined, undulatory, and plump,—seems suited to remind one of
Burns' young Kirk Alloway beauty disporting amid the thin old ladies that
joined with her in the dance. And it is a greatly younger beauty
than the Cambrian and mica-schist protuberances that encroach on the sea
on either side of it. The sheds and kilns of a tile-work occupy the
flat terminal point of the promontory; and as the clay is valuable, in
this tile-draining age, for the facility with which it can be moulded into
pipe-tiles (a purpose which the ordinary clays of the north of Scotland,
composed chiefly of re-formations of the Old Red Sandstone, are what is
technically termed too short to serve), it is gradually retreating
inland before the persevering spade and mattock of the labourer. The
deposit has already been drawn out into many hundred miles of cylindrical
pipes, and is destined to be drawn out into many thousands more,—such
being one of the strange metamorphoses effected in the geologic
formations, now that that curious animal the Bimana has come upon the
stage; and at length it will have no existence in the country, save as an
immense system of veins and arteries underlying the vegetable mould.
Will these veins and arteries, I marvel, form, in their turn, the
fossils of another period, when a higher platform than that into which
they have been laid will be occupied to the full by plants and animals
specifically different from those of the present scene of things,—the
existences of a happier and more finished creation? My business
to-day, however, was with the fossils which the deposit now contains,—not
with those which it may ultimately form.
The Blackpots clay is of a dark-bluish or greenish-gray
colour, and so adhesive, that I now felt, when walking among it, after the
softening rains of the previous night and morning, as if I had got into a
bed of bird-lime. It is thinly charged with rolled pebbles, septaria,
and pieces of a bituminous shale, containing broken Belemnites, and
sorely-flattened Ammonites, that exist as thin films of a white chalky
lime. The pebbles, like those of the boulder-clay of the northern
side of the Moray Frith, are chiefly of the primary rocks and older
sandstones, and were probably in the neighbourhood, in their present
rolled form, long ere the re-formation of the inclosing mass; while the
shale and the septaria are, as shown by their fossils, decidedly Liasic.
I detected among the conchifers a well-marked species of our northern
Lias, figured by Sowerby from Eathie specimens,—the Plagiostoma
concentrica; and among the Cephalopoda, though considerably broken,
the Belemanite elongatus and Belemnite lanceolata, with the
Ammonite Kœnigi (mutabilis),—all Eathie shells. I, besides,
found in the hank a piece of a peculiar-looking quartzose sandstone,
traversed by hard jaspedeous veins of a brownish-gray colour, which I have
never found, in Scotland at least, save associated with the Lias of our
north-eastern coasts. Further, my attention was directed by Dr
Emslie to a fine Lignite in his collection, which had once formed some
eighteen inches or two feet of the trunk of a straight slender
pine,—probably the Pinites Eiggensis,—in which, as in most woods of
the Lias and Oolite, the annual rings are as strongly marked as in the
existing firs or larches of our hill-sides. [2]
The Blackpots deposit is evidently a re-formation of a Liasic
patch, identical, both in mineralogical character and in its organic
remains, with the lower beds of the Eathie Lias; while the fragments of
shale which it contains belong chiefly to an upper Liasic bed. So
rich is the dark-coloured tenacious argil of the Inferior Lias of Eathie,
that the geologist who walks over it when it is still moist with the
receding tide would do well to look to his footing; the mixture of soap
and grease spread by the ship-carpenter on his launch-slips, to facilitate
the progress of his vessel seawards, is not more treacherous to the tread:
while the Upper Liasic deposit which rests over it is composed of a dark
slaty shale, largely charged with bitumen. And of a Liasic deposit
of this compound character, consisting in larger part of an inferior
argillaceous bed, and in lesser part of a superior one of dark shale, the
tile-clay of Blackpots has been formed.
I had next to determine whether aught remained to indicate
the period of its re-formation. The tile-works at the point of the
promontory rest on a bed of shell-sand, composed exclusively, like the
sand so abundant on the western coast of Scotland, of fragments of
existing shells. These, however, are so fresh and firm, that, though
the stratum which they form seems to underlie the clay at its edges, I
cannot regard them as older than the most modern of our ancient
sea-margins. They formed, in all probability, in the days of the old
coast line, a white shelly beach, under such a precipitous front of the
dark clay as argillaceous deposits almost always present to the
undermining wear of the waves. On the recession of the sea, however,
to its present line, the abrupt, steep front, loosened by the frosts and
washed by the rains, would of course gradually moulder down over them into
a slope; and there would thus be communicated to the shelly stratum, at
least at its edges, an underlying character. The true period of the
re-formation of the deposit was, I can have no doubt, that of the
boulder-clay. I observed that the septaria and larger masses of
shale which the bed contains, bear, on roughly-polished surfaces, in the
line of their larger axes, the mysterious groovings and scratchings of
this period,—marks which I have never yet known to fail in their
chronological evidence. It may be mentioned, too, simply as a fact,
though one of less value than the other, that the deposit occurs in its
larger development exactly where, in the average, the boulder-clays also
are most largely developed,—a little over that line where the waves for so
many ages charged against the coast, ere the last upheaval of the land or
the recession of the sea sent them back to their present margin.
There had probably existed to the west or north-west of the deposit,
perhaps in the middle of the open bay formed by the promontory on which it
rests,—for the small proportion of other than Liasic materials which it
contains serves to show that it could be derived from no great
distance,—an outlier of the Lower Lias. The icebergs of the cold
glacial period, propelled along the submerged land by some arctic current,
or caught up by the gulf-stream, gradually grated it down, as a mason's
labourer grates down the surface of the sandstone slab which he is engaged
in polishing; and the comminuted debris, borne eastwards by the current,
was cast down here. It has been stated that no Liasic remains have
been found in the boulder-clays of Scotland. They are certainly rare
in the boulder-clays of the northern shores of the Moray Frith; for there
the nearest Lias, bearing in a western direction from the clay, is that of
Applecross, on the other side of the island; and the materials of the
boulder-deposits of the north have invariably been derived in the line,
westerly in its general bearing, of the grooves and scratches of the
iceberg era. But on the southern shore of the frith, where that
westerly line passed athwart the Liasic beds of our eastern coast,
organisms of the Lias are comparatively common in the boulder-clays; and
here, at Blackpots, we find an extensive deposit of the same period formed
of Liasic materials almost exclusively. Fragments of still more
modern rocks occur in the boulderclays of Caithness. My friend Mr
Robert Dick of Thurso, to whose persevering labours and interesting
discoveries in the Old Red Sandstone of his locality I have had frequent
occasion to refer, has detected in a blue boulder-clay, scooped into
precipitous banks by the river Thorsa, fragments both of chalk-flints and
a characteristic conglomerate of the Oolite. He has, besides, found
it mottled from top to bottom, a full hundred feet over the sea-level, and
about two miles inland, with comminuted fragments of existing shells.
But of this more anon. |
