blood of its thousands of human victims. The temple of Mexico and many others of its type may have been the embodiment of the same principles of architecture employed at Cahokia, but carried to greater perfection under the more favorable conditions afforded in the valley of Anahuac, or precisely the reverse may be true. Such speculations are, however, more easily set forth than sustained. Dr. Foster, through a mistake, states that the monster mound has been removed. This, we are happy to say, is not the case.[29] [Illustration: Drilled Ceremonial Weapons. (Nat. Mus.)] Numerous interesting explorations have been conducted recently in Illinois with rich results. Among the most notable of these are the discoveries of Mr. Henry R. Howland, reported in a paper read before the Buffalo Society of Natural Sciences, March, 1877 (_Bulletin of the Buffalo Soc. of Nat. Sc._, vol. iii., p. 204 _et seq._). In January, 1876, Mr. Howland witnessed the removal of a mound near Mitchell Station in the American Bottom. In a stratum four or five feet from the base, composed chiefly of human bones, a large quantity of matting and a number of copper relics were disclosed to view. The matting was a coarse vegetable cane-like fibre simply woven, without twisting. Among the articles wrapped in the matting were several miniature tortoise shells formed of copper. They were of beaten copper of one sixty-fourth of an inch in thickness, the largest being but two and one-eighth inches in length. “A narrow flange or rim, about five thirty-secondths of an inch in width, is neatly turned at the base, and over the entire outer surface the curious markings peculiar to the tortoise shell are carefully produced by indentation—the entire workmanship evincing a delicate skill of which we have never before found traces in any discovered remains of the arts of the Mound-builders.” These shells were covered with several wrappings, the first and nearest to the shell proving to be of vegetable fibre, the second of a dark-brown color; when placed under the microscope and examined by Dr. G. J. Engleman and Sir Joseph Hooker, proved to be a very fine cloth woven from animal hair—of the rabbit and possibly of the deer. The third envelope was made from the intestine of some animal. The lower jaws of deer were discovered in which the forward part containing the teeth were encased in thin copper and wrapped in the fine hair-cloth just described. From holes bored in the back of each jaw, it is inferred that the articles were suspended from the neck as totems or badges of authority. Three wooden spool-like objects were found in the same place, partially plated with thin copper. Copper rods or needles from fourteen to eighteen inches in length, a beautiful shell necklace, and a spear head of chert a foot long, were also discovered. Among the rest were several sea-shells (_Busycon Perversum_), evidently brought from the Gulf a thousand miles distant. In the summer of 1874, Mr. H. R.
