The pups and yearlings have an especial fondness for sporting on rocks which are just at the water’s level and awash, so as to be covered and uncovered as the surf rolls in. On the bare summit of these wave-worn spots they will struggle and clamber, in groups of a dozen or two at a time, throughout the whole day in endeavoring to push off that one of their number which has just been fortunate enough to secure a landing. The successor has, however, but a brief moment of exultation in victory, for the next roller that comes booming in, together with that pressure by its friends, turns the table, and the game is repeated, with another seal on top. Sometimes, as well as I could see, the same squad of “holluschickie” played for an entire day and night, without a moment’s cessation, around such a rock as this off “Nah Speel” rookery; still, in this observation I may be mistaken, because those seals could not be told apart.
That graceful unconcern with which fur-seals sport safely in, among, and under booming breakers, during the prevalence of numerous wild gales at the islands, has afforded me many consecutive hours of spell-bound attention to them, absorbed in watching their adroit evolutions within the foaming surf, that seemingly every moment would, in its fierce convulsions, dash these hardy swimmers, stunned and lifeless, against those iron-bound foundations of the shore which alone checked the furious rush of the waves. Not at all. Through the wildest and most ungovernable mood of a roaring tempest and storm-tossed waters attending its transit I never failed, on creeping out and peering over the bluffs in such weather, to see squads of these perfect watermen, the most expert of all amphibians, gambolling in the seething, creamy wake of mighty rollers which constantly broke in thunder-tones over their alert, dodging heads. The swift succeeding waves seemed every instant to poise those seals at the very verge of death; yet the Callorhinus, exulting in his skill and strength, bade defiance to their wrath and continued his diversions.
Fur-seals rising to breathe and look around.
[Characteristic pelagic attitude of the “holluschickie.”]
The “holluschickie” are the champion swimmers of all the seal tribe; at least, when in the water around the islands, they do nearly every fancy tumble and turn that can be executed. The grave old males and their matronly companions seldom indulge in any extravagant display, as do these youngsters, which jump out of the water like so many dolphins, describing beautiful elliptic curves sheer above its surface, rising three and even four feet from the sea, with the back slightly arched, the fore flippers folded tightly against the sides, and the hinder ones extended and pressed together straight out behind, plumping in head first, to reappear in the same manner, after an interval of a few seconds of submarine swimming, swift as the flight of a bird on its course. Sea-lions and hair-seals never leap in this manner.
All classes will invariably make these dolphin-jumps when they are surprised or are driven into the water, curiously turning their heads while sailing in the air, between the “rises” and “plumps,” to take a look at the cause of their disturbance. They all swim rapidly, with the exception of the pups, and may be said to dart under the water with the velocity of a bird on the wing. As they swim they are invariably submerged, running along horizontally about two or three feet below the surface, guiding their course with the hind flippers, as by an oar, and propelling themselves solely by the fore feet, rising to breathe at intervals which are either very frequent or else so wide apart that it is impossible to see the speeding animal when he rises a second time.[124]
How long they can remain under water without taking a fresh breath is a problem which I had not the heart to solve, by instituting a series of experiments at the island; but I am inclined to think that, if the truth were known in regard to their ability of going without rising to breathe, it would be considered astounding. On this point, however, I have no data worth discussing, but will say that in all their swimming which I have had a chance to study, as they passed under the water, mirrored to my eyes from the bluff above by the whitish-colored rocks below the rookery waters at Great Eastern rookery, I have not been able to satisfy myself how they used their long, flexible hind-feet, other than as steering media. If these posterior members have any perceptible motion, it is so rapid that my eye is not quick enough to catch it; but the fore flippers, however, can be most distinctly seen as they work in feathering forward and sweeping flatly back, opposed to the water, with great rapidity and energy. They are evidently the sole propulsive power of the fur-seal in the water, as they are its main fulcrum and lever combined for progression on land. I regret that the shy nature of the hair-seal never allowed me to study its swimming motions, but it seems to be a general point of agreement among authorities on the Phocidæ, that all motion in water by them arises from that power which they exert and apply with the hind-feet. So far as my observations on the hair-seal go, I am inclined to agree with this opinion.
All their movements in water, no matter whether travelling to some objective point or merely in sport, are quick and joyous, and nothing is more suggestive of intense satisfaction and pure physical comfort than is that spectacle which we can see every August a short distance at sea from any rookery, where thousands of old males and females are idly rolling over in the billows side by side, rubbing and scratching with their fore and hind flippers, which are here and there stuck up out of the water by their owners, like so many lateen-sails of Mediterranean feluccas, or, when their hind flippers are presented, like a “cat-o’-nine tails.” They sleep in the water a great deal, too, more than is generally supposed, showing that they do not come ashore to rest—very clearly not.
How fast the fur-seal can swim, when doing its best, I am naturally unable to state. I do know that a squad of young “holluschickie” followed the Reliance, in which I was sailing, down from the latitude of the Seal Islands to Akootan Pass with perfect ease; playing around the vessel while she was logging, straight ahead, fourteen knots to the hour.
