an insulated rock on the western coast of Scotland, between the shores of Airshire and Cantire. It is two miles in circumference at the base, is accessible only at one place, and rises to a great height in a pyramidal form. A few goats and rabbits pick up a subsistence among the short grass and furze; but the importance of the rock consists in the great variety and bountiful numbers of birds, by which it is frequented, particularly the gannets or solan-geese, whose young are used at the best tables, and bring a good price. Other birds are caught for their feathers. The rock is rented from the Earl of Cassillis at L. 39 per annum. The depth of water around the base is from 7 to 48 fathoms. It is surrounded with excellent banks, well stocked with cod and other white fish.
