For our knowledge of the external appearance of the mammoth we are indebted to the more or less entire examples which have been found at various times in Siberia, but mainly to the noted specimen found in 1799 near the Lena, embedded in the ice, where it had been reposing, so geologists tell us, anywhere from 10,000 to 50,000 years. How the creature gradually thawed out of its icy tomb, and the tusks were taken by the discoverer and sold for ivory; how the dogs fed upon the flesh in summer, while bears and wolves feasted upon it in winter; how the animal was within an ace of being utterly lost to science when, at the last moment, the mutilated remains were rescued by Mr. Adams, is an old story, often told and retold. Suffice it to say that, besides the bones, enough of the beast was preserved to tell us exactly what was the covering of this ancient elephant, and to show that it was a creature adapted to withstand the northern cold and fitted for living on the branches of the birch and hemlock. [Illustration: Fig. 36.--Skeleton of the Mammoth in the Royal Museum of St. Petersburg.] The exact birthplace of the mammoth is as uncertain as that of many other great characters; but his earliest known resting-place is in the Cromer Forest Beds of England, a country inhabited by him at a time when the German Ocean was dry land and Great Britain part of a peninsula. Here his remains are found to-day, while from the depths of the North Sea the hardy trawlers have dredged hundreds, aye thousands, of mammoth teeth in company with soles and turbot. If, then, the mammoth originated in western Europe, and not in that great graveyard of fossil elephants, northern India, eastward he went spreading over all Europe north of the Pyrenees and Alps, save only Scandinavia, whose glaciers offered no attractions, scattering his bones abundantly by the wayside to serve as marvels for future ages. Strange indeed have been some of the tales to which these and other elephantine remains have given rise when they came to light in the good old days when knowledge of anatomy was small and credulity was great. The least absurd theory concerning them was that they were the bones of the elephants which Hannibal brought from Africa. Occasionally they were brought forward as irrefutable evidences of the deluge; but usually they figured as the bones of giants, the most famous of them being known as Teutobochus, King of the Cimbri, a lusty warrior said to have had a height of nineteen feet. Somewhat smaller, but still of respectable height, fourteen feet, was "Littell Johne" of Scotland, whereof Hector Boece wrote, concluding, in a moralizing tone, "Be quilk (which) it appears how extravegant and squaire pepill grew in oure regioun afore they were effeminat with lust and intemperance of mouth." More than this, these bones have been venerated in Greece and Rome as the remains of pagan heroes, and later on worshipped as relics of Christian saints.
