sort of resting places, though not over soft; and slept so soundly, that we failed to mark Mr. Elder's return for a few seconds, a little after daybreak. I found at my bedside, when I awoke, a fragment of rock which he had brought from the shore, charged with Liasic fossils; and a note he had written, to say that the deposit to which it belonged occurred in the trap immediately above the village-mill; and further, to call my attention to a house near the middle of the village, built of a mouldering red sandstone, which had been found in situ in digging the foundations. I had but little time for the work of exploration in Mull, and the information thus kindly rendered enabled me to economize it.

The village of Tobermory resembles that of Oban. A quiet bay has its secure island-breakwater in front; a line of tall, well-built houses, not in the least rural in their aspect, but that seem rather as if they had been transported from the centre of some stately city entire and at once, sweeps round its inner inflection, like a bent bow; and an amphitheatre of mingled rock and wood rises behind. With all its beauty, however, there hangs about the village an air of melancholy. Like some of the other western coast villages, it seems not to have grown, piece-meal, as a village ought, but to have been made wholesale, as Frankenstein made his man; and to be ever asking, and never more incessantly than when it is at its quietest, why it should have been made at all? The remains of the Florida, a gallant Spanish ship, lie off its shores, a wreck of the Invincible Armada, "deep whelmed," according to Thompson,

"What time,
Snatched sudden by the vengeful blast,
The scattered vessels drove, and on blind shelve,
And pointed rock that marks th' indented shore,
Relentless dashed, where loud the northern main
Howls through the fractured Caledonian isles."

Macculloch relates, that there was an attempt made, rather more than a century ago, to weigh up the Florida, which ended in the weighing up of merely a few of her guns, some of them of iron greatly corroded; and that, on scraping them, they became so hot under the hand that they could not be touched, but that they lost this curious property after a few hours' exposure to the air. There have since been repeated instances elsewhere, he adds, of the same phenomenon, and chemistry has lent its solution of the principles on which it occurs; but, in the year 1740, ere the riddle was read, it must have been deemed a thoroughly magical one by the simple islanders of Mull. It would seem as if the guns, heated in the contest with Drake, Hawkins, and Frobisher, had again kindled, under some supernatural influence, with the intense glow of the lost battle.

The morning was showery; but it cleared up a little after ten, and we landed to explore. We found the mill a little to the south of the village, where a small stream descends, all foam and uproar, from the higher grounds along a rocky channel half-hidden by brushwood; and the Liasic bed occurs in an exposed front directly over it, coped by a thick bed of amygdaloidal trap. The organisms are numerous; and, when we dig into the bank beyond the reach of the weathering influences, we find them delicately preserved, though after a fashion that renders difficult their safe removal. Originally the bed must have existed as a brown argillaceous mud, somewhat resembling that which forms in the course of years, under a scalp of muscles; and it has hardened into a more silt-like clay, in which the fossils occur, not as petrifactions, but as shells in a state of decay, except in some rare cases, in which a calcareous nodule has formed within or around them. Viewed in the group, they seem of an intermediate character, between the shells of the Lias and the Oölite. One of the first fossils I disinterred was the Gryphæa obliquata,—a shell characteristic of the Liasic formation; and the fossil immediately after, the Pholadomy æqualis, a shell of the Oölitic one. There occurs in great numbers a species of small Pecten,—some of the specimens scarce larger than a herring scale; a minute Ostrea, a sulcated Terebratula, an Isocardia, a Pullastra, and groups of broken serpulæ in vast abundance. The deposit has also its three species of Ammonite, existing as mere impressions in the clay; and at least two species of Belemnite,—one of the two somewhat resembling the Belemnites abbreviatus, but smaller and rather more elongated: while the other, of a spindle form, diminishing at both ends, reminds one of the Belemnites minimus of the Gault. The Red Sandstone in the centre of the village occurs detached, like this Liasic bed, amid the prevailing trap, and may be seen in situ beside the southern gable of the tall, deserted looking house at the hill-foot, that has been built of it. It is a soft, coarse-grained, mouldering stone, ill fitted for the purposes of the architect; and more nearly resembles the New Red Sandstone of England and Dumfriesshire, than any other rock I have yet seen in the north of Scotland. I failed to detect in it aught organic.

We weighed anchor about two o'clock, and beat gallantly out the Sound, in the face of an intermittent baffling wind and a heavy swell from the sea. I would fain have approached nearer the precipices of Ardnamurchan, to trace along their inaccessible fronts the strange reticulations of trap figured by Macculloch; but prudence and the skipper forbade our trusting even the docile little Betsey, on one of the most formidable lee shores in Scotland, in winds so light and variable, and with the swell so high. We could hear the deep roar of the surf for miles, and see its undulating strip of white flickering under stack and cliff. The scenery here seems rich in legendary association. At one tack we bore into Bloody Bay, on the Mull coast,—the scene of a naval battle between two island chiefs; at another, we approached, on the mainland, a cave inaccessible save from the sea, long the haunt of a ruthless Highland pirate. Ere we rounded the headland of Ardnamurchan, the slant light of evening was gleaming athwart the green acclivities of Mull, barring them with long horizontal lines of shadow, where the trap terraces rise step beyond step, in the characteristic stair-like arrangement to which the rock owes its name; and the sun set as we were bearing down in one long tack on the Small Isles. We passed the Isle of Muck, with its one low hill; saw the pyramidal mountains of Rum looming tall in the offing; and then, running along the Isle of Eigg, with its colossal Scuir rising between us and the sky, as if it were a piece of Babylonian wall, or of the great wall of China, only vastly larger, set down on the ridge of a mountain, we entered the channel which separates the island from one of its dependencies, Eilean Chaisteil, and cast anchor in the tideway, about fifty yards from the rocks. We were now at home,—the only home which the proprietor of the island permits to the islanders' minister; and, after getting warm and comfortable over the stove and a cup of tea, we did what all sensible men do in their own homes when the night wears late,—got into bed.
