"_19th August, 1814, Loch Eribol, near Cape Wrath._--Went off before eight A. M. to breakfast with our friend Mr. Anderson. His house, invisible from the vessel at her moorings, and indeed from any part of the entrance into Loch Eribol, is a very comfortable one, lying obscured behind a craggy eminence. A little creek, winding up behind the crag, and in front of the house, forms a small harbor, and gives a romantic air of concealment and snugness. There we found a ship upon the stocks, built from the keel by a Highland carpenter, who had magnanimously declined receiving assistance from any of the ship-carpenters who happened to be here occasionally, lest it should be said he could not have finished his task without their aid. An ample Highland breakfast of excellent new-taken herring, equal to those of Lochfine, fresh haddocks, fresh eggs, and fresh butter, not forgetting the bottle of whiskey, and bannocks of barley, and oat-cakes, with the Lowland luxuries of tea and coffee. After breakfast, took the long-boat, and, under Mr. Anderson's pilotage, row to see a remarkable natural curiosity, called Uamh Smowe, or the Largest Cave. Stevenson, Marchie, and Duff go by land. Take the fowling-piece, and shoot some sea-fowl and a large hawk of an uncommon appearance. Fire four shots, and kill three times. After rowing about three miles to the westward of the entrance from the sea to Loch Eribol, we enter a creek, between two ledges of very high rocks, and landing, find ourselves in front of the wonder we came to see. The exterior apartment of the cavern opens under a tremendous rock, facing the creek, and occupies the full space of the ravine where we landed. From the top of the rock to the base of the cavern, as we afterwards discovered by plumb, is eighty feet, of which the height of the arch is fifty-three feet; the rest, being twenty-seven feet, is occupied by the precipitous rock under which it opens; the width is fully in proportion to this great height, being 110 feet. The depth of this exterior cavern is 200 feet, and it is apparently supported by an intermediate column of natural rock. Being open to daylight and the sea-air, the cavern is perfectly clean and dry, and the sides are incrusted with stalactites. This immense cavern is so well proportioned, that I was not aware of its extraordinary height and extent, till I saw our two friends, who had somewhat preceded us, having made the journey by land, appearing like pigmies among its recesses. Afterwards, on entering the cave, I climbed up a sloping rock at its extremity, and was much struck with the prospect, looking outward from this magnificent arched cavern upon our boat and its crew, the view being otherwise bounded by the ledge of rocks which formed each side of the creek. We now propose to investigate the farther wonders of the cave of Smowe. In the right or west side of the cave opens an interior cavern of a different aspect. The height of this second
