"In the early winter we usually found the walrus in smaller groups up in the bays. This was after the ice had begun to make, and in coming to the surface to breathe the animals found it necessary to butt their noses against the ice to break it. I have seen this done in ice at least four inches in thickness. In some instances I have seen a fractured star in the ice, a record of an unsuccessful attempt to make a breathing hole." Around these breathing holes we frequently found fragments of clam-shells, sections of crinoids and sea-anemones. It is evident that after raking the bottom with his tusks and filling his mouth with food, the walrus separates the food he desires to retain and rejects on his way up and at the surface such articles as he has picked up in haste and does not want. "From the fact that the walrus is easily approached it is a simple matter to kill him with the modern high power rule. It is therefore to be hoped that future expeditions into the arctic seas will kill sparingly of these tremendous brutes which from point of size stand in the foremost rank among mammals." The Elephant, Rhinoceros and Hippopotamus. _Individual Elephants_ vary in temperament far more than do rhinoceroses or hippopotami, and the variations are wide. In a wild state, elephants are quiet and undemonstrative, almost to the point of dullness. They do not domineer, or hector, or quarrel, save when a rogue develops in the ranks, and sets out to make things interesting by the commission of lawless acts. A professional rogue is about everything that an orthodox elephant should not be, and he soon makes of himself so great a nuisance that he is driven out of the herd. The temperament of the standardized and normal elephant is distinctly sanguine, _but a nervous or hysterical individual is easily developed by bad conditions or abuse_. Adult male elephants are subject to various degrees of what we may as well call sexual insanity, which is dangerous in direct proportion to its intensity. This causes many a "bad" show elephant to be presented to a zoological garden, where the dangers of this mental condition can at least be reduced to their lowest terms. Our Indian elephant who was known as Gunda was afflicted with sexual insanity, and he gradually grew worse, and increasingly dangerous to his keepers, until finally it was necessary to end his troubles painlessly with a bullet through his brain.
