then advances, striking out right and left toward the position from which it replies; but if the pup happens at this time to be asleep, it gives, of course, no response, even though it were close by. In the event of such silence the cow, after calling for a time without being answered, curls herself up and takes a nap or lazily basks, to be usually more successful, or wholly so, when she calls again. The pups themselves do not know their own mothers, a fact which I ascertained by careful observation; but they are so constituted that they incessantly cry out at short intervals during the whole time they are awake, and in this way the mother can pick out from the monotonous blaating of thousands of pups her own, and she will not permit any other one to suckle her. But the “kotickie” themselves attempt to nose around every seal-mother that comes in contact with them. I have repeatedly watched young pups as they made advances to nurse from another pup’s mother, the result invariably being that, while the “matkah” would permit her own offspring to suckle freely, yet when these little strangers touched her nipples she would either move abruptly away or else turn quickly down upon her stomach, so that the maternal fountains were inaccessible to alien and hungry “kotickie.” I have witnessed so many examples of the females turning pups away to suckle only some particular other one, that I feel sure I am entirely right in saying that the seal-mothers know their own young, and that they will not permit any others except them to nurse. I believe that this maternal recognition is due chiefly to the mother’s scent and hearing. Between the end of July and August 5th or 8th of every year the rookeries are completely changed in appearance. The systematic and regular disposition of the families or harems over the whole extent of breeding-ground has disappeared. All that clock-work order which has heretofore existed seems to be broken up. The breeding season closed, those bulls which have held their positions since May 1st leave, most of them thin in flesh and weak, and of their number a very large proportion do not come out again on land during the season; but such as are seen at the end of October and November are in good shape. They have a new coat of rich, dark, gray-brown hair and fur, with gray or grayish-ochre “wigs” of longer hair over the shoulders, forming a fresh, strong contrast to the dull, rusty, brown and umber dress in which they appeared to us during the summer, and which they had begun to shed about August 1st, in common with the females and the “holluschickie.” After these males leave at the end of their season’s work, and of the rutting for the year, those of them that happen to return to land in any event do not come back until the end of September and do not haul up on the rookery grounds again. As a rule, they prefer to herd altogether, like younger males, upon the sand-beaches and rocky points close to the water.
