This is the mammoth, the _Elephas primigenius_ of Blumenbach, a gigantic elephant nearly a third taller than the largest modern species, and twice its weight. Its body was protected from the severity of the semi-arctic conditions under which it flourished by a dense covering of reddish wool, and long black hair, and its head was armed or ornamented with tusks exceeding twelve feet in length, and curiously curved into three parts of a circle. Its ivory has long been, and still is, a valuable article of commerce, more especially in North-eastern Asia, and in Eschscholtz Bay in North America, near Behring's straits, where entire skeletons are occasionally discovered, and where even the nature of its food has been ascertained from the undigested contents of its stomach. There is a well-known case recorded of a specimen found (1799), frozen and encased in ice, at the mouth of the Lena. It was sixteen feet long, and the flesh was so well preserved that the Yakuts used it as food for their dogs. But similar instances occurred previously, for we find the illustrious savant and Emperor Kang Hi [A.D. 1662 to 1723] penning the following note[42] upon what could only have been this species:-- "The cold is extreme, and nearly continuous on the coasts of the northern sea beyond Tai-Tong-Kiang. It is on this coast that the animal called Fen Chou is found, the form of which resembles that of a rat, but which equals an elephant in size. It lives in obscure caverns, and flies from the light. There is obtained from it an ivory as white as that of the elephant, but easier to work, and which will not split. Its flesh is very cold and excellent for refreshing the blood. The ancient work Chin-y-king speaks of this animal in these terms: 'There is in the depths of the north a rat which weighs as much as a thousand pounds; its flesh is very good for those who are heated.' The Tsée-Chou calls it Tai-Chou and speaks of another species which is not so large. It says that this is as big as a buffalo, buries itself like a mole, flies the light, and remains nearly always under ground; it is said that it would die if it saw the light of the sun or even that of the moon." [Illustration: FIG. 10.--TOOTH OF THE MAMMOTH. (_After Figuier._)] It seems probable that discoveries of mammoth tusks formed in part the basis for the story which Pliny tells in reference to fossil ivory. He says[43]:--"These animals [elephants] are well aware that the only spoil that we are anxious to procure of them is the part which forms their weapon of defence, by Juba called their horns, but by Herodotus, a much older writer, as well as by general usage, and more appropriately, their teeth. Hence it is that, when these tusks have fallen off, either from accident or old age, they bury them in the earth."
