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 Oolite. One of the first fossils I disinterred was the Gryphaea obliquata,--a shell characteristic of the Liasic formation; and the fossil immediately after, the Pholadomy aequalis, a shell of the Oolitic 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 serpulae 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.
