The murder of the aged and helpless among wild animals is almost unknown; but among both the savage and the civilized races of men it is quite common. Our old acquaintance, Shack-Nasty Jim, the Modoc Indian, tomahawked his own mother because she hindered his progress; but many persons in and around New York have done worse than that.
Civil war between the members of a wild animal species is a thing unknown in the annals of wild-animal history; but among men it is an every-day occurrence.
Among free animals it is against the moral and ethical codes of all species of vertebrates for the strong to bully and oppress the weak; but it is almost everywhere a common rule of action with about ten per cent of the human race.
The members of a wild animal species are in honor bound not to rob one another, but with 25 per cent of the men of all civilized races, robbery, and the desire to get something for nothing, are ruling passions. No wild animals thus far known and described practice sex crimes; but the less said of the races of men on this subject, the better for our feelings.
Among animals, save in the warfare of carnivorous animals for their daily food, there are no exterminatory wars between species, and even local wars over territory are of very rare occurrence. Among men, the territorial wars of tribes and nations are innumerable, they have been from the earliest historic times, and they are certain to continue as long as this earth is inhabited by man. The "end of war" between the grasping nations of this earth is an iridescent dream, because of the inextinguishable jealousy and meanness of nations; but it is well to reduce them to a minimum. Nations like Germany, Bulgaria, Turkey and Russia will never stand hitched for any long periods. Their peace-loving neighbors need to keep their weapons well oiled and polished, and indulge in no hallucinations of a millenium upon this wicked earth.
In the mating season, there is fighting in many wild animal species between the largest and finest male individuals for the honor of overlordship in increasing and diffusing the species. These encounters are most noticeable in the various species of the deer family, because the fatal interlocking of antlers occasionally causes the death of both contestants. We have in our National Collection of Heads and Horns sets of interlocked antlers of moose, caribou, mule deer and white-tailed deer.
Otherwise than from the accidental interlocking of antlers,—due to the fact that an animal can push forward with far greater force than it can pull back,—I have never seen, heard or read of a wild animal having been killed outright in a fight over the possession of females. Fur seal and Stellar sea-lion bulls, and big male orang-utans, frequently are found badly scarified by wounds received in fighting during the breeding season, but of actual deaths we have not heard.
The first law of the jungle is: "Live, and let live."
Leaving out of account the carnivorous animals who must kill or die, all the wild vertebrate species of the earth have learned the logic that peace promotes happiness, prosperity and long life. This fundamentally useful knowledge governs not only the wild animal individual, but also the tribe, the species, and contiguous species.
Do the brown bears and grizzlies of Alaska wage war upon each other, species against species? By no means. It seems reasonably certain that those species occasionally intermarry. Do the big sea-lions and the walruses seek to drive away or exterminate the neighboring fur seals or the helpless hair seals? Such warfare is absolutely unknown. Do the moose and caribou of Alaska and Yukon Territory attack the mountain sheep and goats? Never. Does the Indian elephant attack the gaur, the sambar, the axis deer or the muntjac? The idea is preposterous. Does any species of giraffe, zebra, antelope or buffalo attack any other species on the same crowded plains of British East Africa? If so, we have yet to learn of it.
