Undoubtedly some abnormal birth-shapes must make their appearance occasionally; but at no time while I was there, searching keenly for any such manifestation of malformation on the rookeries, did I see a single example. The morphological symmetry of the fur-seal is one of the most salient of its characteristics, viewed as it rallies here in such vast numbers; but the osteological differentiation and asymmetry of this animal is equally surprising.
It is perfectly plain that a large percentage of this immense number of seals must die every year from natural limitation of life. They do not die on these islands; that much I am certain of. Not one dying a natural death could I find or hear of on the grounds. They evidently lose their lives at sea, preferring to sink with the rigor mortis into that cold, blue depth of the great Pacific, or beneath the green waves of Bering Sea, rather than to encumber and disfigure their summer haunts on the Pribylov Islands.
Prior to the year 1835, no native on the islands seemed to have any direct knowledge, or was even acquainted with a legendary tradition, in relation to the seals, concerning their area and distribution on the land here; but they all chimed in after that date with great unanimity, saying that the winter preceding this season (1835-36) was one of frightful severity; that many of their ancestors who had lived on these islands in large barraboras just back of the Black Bluffs, near the present village, and at Polavina, then perished miserably.
They say that the cold continued far into the summer; that immense masses of clearer and stronger ice-floes than had ever been known to the waters about the islands, or were ever seen since, were brought down and shoved high up on to all the rookery margins, forming an icy wall completely around the island, and loomed twenty to thirty feet above the surf. They further state that this frigid cordon did not melt or in any way disappear until the middle or end of August, 1836.
They affirm that for this reason the fur-seals, when they attempted to land, according to their habit and their necessity, during June and July, were unable to do so in any considerable numbers. The females were compelled to bring forth their young in the water and at the wet, storm-beaten surf-margins, which caused multitudes of mothers and all of the young; to perish. In short, the result was a virtual annihilation of the breeding-seals Hence, at the following season, only a speetrl-a shadowy imitation
