Many are the instances of pieces of timber found, various depths below the surface of the earth, with the marks of the axe palpably visible on them.[13] A sword too, said to have been enclosed in the wood of the roots of a tree not less than five hundred years old, is preserved in Ohio as a curiosity. Many other instances might, if necessary, be adduced to prove, that implements of iron were in use in this country, prior to its occupation by the whites. Now if a people once have the use of that metal, it is far from probable that it will ever after be lost to them: the essential purposes to which it may be applied, would preserve it to them. The Indians however, 'till taught by the Europeans, had no knowledge of it. Many of the antiquities discovered in other parts of the country, show that the arts once flourished to an extent beyond what they have ever been known to do among the Indians. The body found in the saltpetre cave of Kentucky, was wrapped in blankets made of linen and interwoven with feathers of the wild turkey, tastefully arranged. It was much smaller than persons of equal age at the present day, and had yellowish hair. In Tennessee many walls of faced stone, and even walled wells have been found in so many places, at such depths and under such circumstances, as to preclude the idea of their having been made by the whites since the discovery by Columbus. [38] In this state too, have been found burying grounds, in which the skeletons seem all to have been those of pigmies: the graves, in which the bodies had been deposited, were seldom three feet in length; yet the teeth in the skulls prove that they were the bodies of persons of mature age. Upon the whole there cannot be much doubt, that America was once inhabited by a people, not otherwise allied to the Indians of the present day, than that they were descendants of him, from whom has sprung the whole human family. ----- [1] It is said that the nerves of an Indian do not shrink as much, nor shew the same tendency to spasm, under the knife of the surgeon, as the nerves of a white man in a similar situation.
