Peterhead appeared to be a bustling place.  A number of merchant vessels, coasters, and fishing-boats were at anchor.  As the days were long, we hoped the gale would blow itself out before the next morning. Directly we had dined we set off on foot to visit a curious cavern called the "Bullers of Buchan."  After walking for about two hours we found ourselves on the top of a cliff, from whence we looked down into an immense cauldron some fifty feet in diameter, open at the bottom to the sea, which was rushing in, and whirling round and round in foaming masses.  We went round it, between the cauldron and the sea, where the ledge, with the foaming whirlpool on one side and the perpendicular cliffs on the other, was sufficiently narrow to make us feel the necessity of keeping our eyes open.  On the west side, or the furthest from the ocean, we observed that the water rushed under an arch.  A person told us that in fine weather a boat could pass under this arch, though at present one would have been immediately dashed to pieces.  The whole cliff was completely perforated by caverns.  "Buller," I should have said, means the "boiler."  Having watched it until our ears were wellnigh deafened by the roar, and our eyes dizzy from gazing at the seething whirlpool, we hastened on to get a sight of Slaines Castle, which we had seen from the sea.  As we viewed it from a distance, the walls appeared to be a continuation of the cliff on the summit of which it stands.  It is a large quadrangular building, without a tree in the neighbourhood.  It had a somewhat gloomy aspect under the dark sky when we saw it.  The property belonged, till lately, to the Earl of Errol, whose nearest neighbour to the eastward was, as Dick said, "Hamlet's Ghost," or the Castle of Elsinore, which stands on the shores of the Skagerack.
