The most remarkable instance of the supposed, or we might be allowed in this case to say _pretended_ discovery of human remains in association with those of extinct animals, is that set forth by Dr. Koch. This collector of curiosities described his discovery of a _mastodon giganteus_ in 1839 in Gasconade County, Missouri, at a spot on the Bourbeuse River, first in a newspaper article of January 1839, and cited in the _American Journal of Science and Arts_.[122] And a second time in the St. Louis _Commercial Bulletin_ of June 25, 1839, which article was also noticed in the above Journal.[123] This article was signed “A. Koch, Proprietor of the St. Louis Museum.” Subsequently he published descriptions in pamphlets, which unfortunately did not always convey the same impressions.[124] Dr. Koch, after referring to the discovery of a back and hip bone of this remarkable animal, gives the following description: “I immediately commenced opening a much larger space; the first layer of earth was a vegetable mould, then a blue clay, then sand and blue clay. I found a large quantity of pieces of rocks, weighing from two to twenty-five pounds each, evidently thrown there with the intention of hitting some object. It is necessary to remark that not the least sign of rocks or gravel is to be found nearer than from four or five hundred yards, and that these pieces were broken from larger rocks, and consequently carried here for some express purpose. After passing through these rocks I came to a layer of vegetable mould; on the surface of this was found the first blue bone, with this a spear and axe; the spear corresponds precisely with our common Indian spear; the axe is different from any I have seen. Also on this earth were ashes nearly from six inches to one foot in depth, intermixed with burned wood and burned bones, broken spears, axes, knives, etc. The fire appeared to have been the largest on the head and neck of the animal, as the ashes and coals were much deeper here than in the rest of the body; the skull was quite perfect, but so much burned that it crumbled to dust on the least touch; two feet from this was found two teeth broken off from the jaw, but mashed entirely to pieces. By putting them together, they showed the animal to have been much larger than any heretofore discovered. It appeared by the situation of the skeleton, that the animal had been sunk with its hind feet in the mud and water, and, unable to extricate itself, had fallen on its right side, and in that situation was found and killed as above described; consequently the hind and fore-feet on the right side were sunk deeper in the mud, and thereby saved from the effects of the fire; therefore I was able to preserve the whole of the hind foot to the very last joint, and the fore foot, all but some few small bones that were too much decayed to be worth saving. Also between the rocks that had sunk through the ashes, were found large pieces of skin that appeared
