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-colored 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 canvas 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 unfavorable, 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 laborers 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 reäppear, 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 Banffshires, 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 subsoils, 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 neighborhood 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 skepticism, 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 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 a 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 as 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-colored 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 hand; 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 gude-wife 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 laborer at work with a pickaxe, 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 laborer 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 Cummingiæ; and here the spine of the anterior dorsal of Diplacanthus striatus." My reading of the fossils was at once recognized, 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 neighborhood (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.
