The evidence of the existence of the mastodon and mammoth at the same time with man in America, is now placed beyond a doubt, as is that of the wooly mammoth in Europe, coeval with the savage human races there. The traditions of the Delaware Indians mentioned by Pres. Jefferson in his “Notes” p. 79, and of the western tribes given by Dr. Albert Koch a German fossil hunter in this country 30 years ago, in his “Description” of his Theristocaulodon (mammoth) p. 10–13, all show that these megatherioid animals did not die out till man appeared. Koch found evidence under the remains of the mastodon and mammoth, by arrow heads and charcoal, that man had been concerned in the death of these animals. Ibid. pp. 25 to 27. At a depth of 150 ft or more, in the gold bearing gravel, beneath Table Mountain, California, a human skull was found in connection with the remains of the mastodon and tapir, and a human pelvic bone was found at Natchez, Miss. associated with the bones of the mastodon, megalonyx, and native horse. See “Am Naturalist” for September 1868 p. 386, and Am. Jour. Sci. for May 1868, p. 378. Dr. John C. Warren in his monograph on his great Mastodon tells us that hair of a dun color, from 3 to 7 in. long was found with it. p. 148.
