In America, we have traces of a race of savages as old or older than the now famous river-drift and cave-men of Europe. Since the "Calaveras Man" lived, a valley, say geologists, has been metamorphosed, by the slow processes of nature, into a mountain; and the "San Joachim plummet," the "Trenton gravel-flints," and stone implements from the gold-bearing gravels of California, all speak of a race of human beings who must have lived in the time of the hairy mammoth. But who were these people? Were they Indians? or had the Indian or his ancestor the mound-builder not yet appeared? and how many thousands or tens of thousands of years ago did they exist? These are questions which archæology has not yet answered. Here, however, with the carving before us we need not go back so far, nor beyond the Indian as we know him--the fierce, roving, bauble-loving, picture-making hunter of to-day. A study of the wonderful outlines on the stone will lead us through a period of his history extending over many hundreds, perhaps thousands, of years before the coming of Columbus; and here we may try to read, from the few vestiges of this time that chance has preserved to us, fragments of his picturesque mythology, strange legends of his origin and wanderings over a forest-covered continent, and the thrilling story of the mound-builders, and of long wars when the forest soil for centuries was a "dark and bloody ground."[D] That the mammoth had survived into the time of the Indian can hardly be doubted. Early travellers had frequently seen its bones at the "Big-Bone Licks" in Kentucky, whither the huge animals had come, like the deer and buffalo of modern times, to lick the salt. The great bones often seemed hardly older than those of the modern animals with which they were mingled, and, judging from their position along the modern buffalo-trails through the forest, it seems that the latter animals had followed the ancient tracks of the mammoth to and from the licks. Not a few of these early travellers thought it worth their while to question the Indians about the huge bones and note down their answers. Jefferson, in his "Notes on Virginia," devotes several pages to the subject. He even believes the mammoth to be still in existence in his time in some remote part of the American continent. He tells the story of a Mr. Stanley, who, "taken prisoner by the Indians near the mouth of the Tanissee," relates that "after being transferred through several tribes from one to another, he was at length carried over the mountains west of the Missouri to a river which runs westwardly; that these bones abounded there, and that the natives described to him the animal to which they belonged as still existing in the northern parts of their country, from which description he judged it to be an elephant."
