narrow channel on the other. It has its name and its colour from the dung of innumerable seafowls, which, in the spring, choose this place, as convenient for incubation, and have their eggs and their young taken in great abundance. One of the birds that frequent this rock has, as we were told, its body not larger than a duck's, and yet lays eggs as large as those of a goose. This bird is by the inhabitants named a coot. That which is called coot in England is here a cooter.
Upon these rocks there was nothing that could long detain attention, and we soon turned our eyes to the Buller, or Bouilloir of Buchan, which no man can see with indifference, who has either sense of danger, or delight in rarity. It is a rock perpendicularly tubulated, united on one side with a high shore, and on the other rising steep to a great height above the mainsea. The top is open, from which may be seen a dark gulf of water which flows into the cavity, through a breach made in the lower part of the enclosing rock. It has the appearance of a vast well bordered with a wall. The edge of the Buller is not wide, and to those that walk round, appears very narrow. He that ventures to look downward sees, that if his foot should slip, he must fall from his dreadful elevation upon stones on one side, or into the water on the other. We, however, went round, and were glad when the circuit was completed.
When we came down to the sea, we saw some boats, and rowers, and resolved to explore the Buller, at the bottom. We entered the arch, which the water had made, and found ourselves in a place, which, though we could not think ourselves in danger, we could scarcely survey without some recoil of the mind. The basin, in which we floated, was nearly circular, perhaps, thirty yards in diameter. We were enclosed by a natural wall, rising steep on every side to a height which produced the idea of insurmountable confinement. The interception of all lateral light caused a dismal gloom. Round us was a perpendicular rock, above us the distant sky, and below an un-
