This low, tiny, island is, perhaps, the most interesting single spot now known to the naturalist who may land in northern seas, to study the habits of bird-life; for here, without exertion or risk, he can observe and walk among tens upon tens of thousands of screaming water-fowl; and, as he sits down upon the polished lava rock, he becomes literally ignored and environed by these feathered friends, as they reassume their varied positions of incubation, from which he disturbs them by his arrival. Generation after generation of their kind have resorted to this rock unmolested, and to-day, when you get among them, all doubt and distrust seem to have been eliminated from their natures. The island itself is rather unusual in those formations which we find peculiar to Alaskan waters. It is almost flat, with slight, irregular undulations on top, spreading over an area of five acres perhaps. It rises abruptly, though low, from the sea, and it has no safe beach upon which a person can land from a boat; not a stick of timber or twig of shrubbery ever grew upon it, though the scant presence of low, crawling grasses in the central portions prevents the statement that _all_ vegetation is absent. Were it not for the frequent rains and dissolving fog characteristic of summer weather here, the accumulation of guano would be something wonderful to contemplate—Peru would have a rival. As it is, however, the birds, when they return, year after year, find their nesting-floor swept as clean as though they had never sojourned there before. The scene of confusion and uproar that presented itself to my astonished senses when I approached this place in search of eggs, one threatening, foggy July morning, may be better imagined than described, for, as the clumsy bidarrah came under the lee of the low cliffs, swarm upon swarm of thousands of murres or “arries” dropped in fright from their nesting-shelves, and, before they had control of their flight, they struck to the right and left of me, like so many cannon-balls. I was forced, in self-protection, to instantly crouch for a few moments under the gunwale of the boat until the struggling, startled flock passed, like an irresistible, surging wave, over my head. Words cannot depict the amazement and curiosity with which I gazed around after climbing up to the rocky plateau, and stood among myriads of breeding-birds; they fairly covered the entire surface of the island with their shrinking forms, while others whirled in rapid flight over my head, as wheels within wheels, so thickly inter-running that the blue and gray of the sky was hidden from my view. Add to this impression the stunning whir of hundreds of thousands of strong, beating wings, the shrill screams of the gulls, and a muffled croaking of the “arries,” coupled with an indescribable, disagreeable smell which arose from broken eggs and other decaying substances—then a faint idea may be evoked of the strange reality spread before me.
