"There is a small island, Scotsmen call it the Bass (let it serve as a type of all the rest), lying near the shore, but in deep water. It is so rugged and precipitous that it might rather be called a huge stone or rock than an island, for it is not more than a mile in circumference. The whole surface of the island in the months of May and June is almost completely carpeted with nests, birds, and fledglings. There are so many that you can scarcely avoid stepping upon them, and when they fly the crowd is so great that it hides the sun and the sky like a cloud. The screaming and the din too are so great that you can hardly hear any one speaking close to you. If you look down upon the sea, as if from a tower or tall precipice, whichever way you turn you will see an enormous number of different kinds of birds skimming about and gaping for their prey, so that the sea looks like a pond which is swarming with frogs in springtime, or like those sunny hills looked at from below when they are covered with numerous flocks of sheep and goats. If you sail round the island and look up you see on every ledge, shelf, and recess innumerable flocks of birds of every sort and size, more numerous than the stars seen at night in the unclouded moonless sky, and if you watch the flights that come and go incessantly, you might imagine that it was a mighty swarm of bees. I should hardly be believed if I said what a large revenue was obtained annually from the feathers and from the old nests (used for firing) and from the eggs, which are boiled and then sold, though the owner told me himself. There is one feature, too, which seems to be especially worthy of note because it bears closely upon my argument and is clear proof of what I have just said about the crowd of birds. The whole island shines brilliantly white to those who approach it, and the cliffs are as bright as if they were made of the whitest chalk; yet the natural colour of the rock is dusky and black. It is due to a brittle crust of the whitest colour that is spread over all and gives the island its whiteness and brilliancy, a crust of the same consistence, colour, and nature as the shell of an egg."
