Speaking of the interior of the country, we have the authority of Mr. C. F. Fowler, late agent of the Alaska Fur Company, and long resident in the country, and of Ex-Governor Swineford, both of whom have carefully investigated the subject, for stating that there exists a huge species of animals, believed to be representatives of the supposed extinct mammoth, found in herds not far from the headwaters of the Snake River, on the interior plateaus of Alaska. The natives call them “big-teeth” because of the size of their ivory tusks. Some of these, weighing over two hundred pounds each, were from animals so lately killed as to still have flesh upon them, and were purchased by Mr. Fowler, who brought them to the coast. These mammoths are represented to average twenty feet in height and over thirty feet in length, in many respects resembling elephants, the body being covered with long, coarse, reddish hairs. The eyes are larger, the ears smaller, and the trunk longer and more slender than those of the average elephant. The two tusks which Mr. Fowler brought away with him each measured fifteen feet in length. The author has almost universally found among savage races at least a few very old people of both sexes, who were apparently revered and carefully provided for by their descendants and associates, but here among the aborigines aged persons are certainly not often to be seen. Whether it is that, hardy and robust as they generally appear to be, they do not, as a rule, live to advanced years, or that a summary method is adopted to get rid of them after they have outlived their usefulness, it is impossible to say. We were told that such is certainly the case with some of the tribes farthest from the influence and supervision of the whites, and that half a century ago the extremely old, being considered useless, were frequently “disposed” of. It is clear enough that there is nothing in the climate of this region in any way inimical to health and longevity.
