In the collections I have named, as well as in those of Mr. Cleneay and Mr. James of Cincinnati, and of Mr. Merrin and Mr. Shrock of Newark, the examples of flint and stone implements number many hundreds, and would require a volume not less ample than Mr. John Evans’s comprehensive monograph of _The Ancient Stone Implements_, _Weapons, and Ornaments of Great Britain_, to illustrate their details. I shall limit myself here to a few examples selected from among those peculiar to the neolithic art of the New World which offer any suggestive hint relative to the origin or use of objects already familiar to the archæologist. Perforated teeth of bears and other animals occur among the mound relics; shell beads are still more abundant; bone and horn pins and lance-heads, and a peculiar class of stone implements, most frequently made of a striated, grey or blue shale, perforated with two or more holes, are all of common occurrence. The chief varieties are shown in the _Ancient Monuments of the Mississippi Valley_, Fig. 136, p. 237. Some of them bear so near a resemblance to the bracers, or guards, found in British graves, and supposed to have been worn on the left arm to protect it from the recoil of the string in the use of the bow, that I am inclined to ascribe the same purpose to them. But others are curved at the edges, and frequently of too large a size for this purpose. The latter are also occasionally formed of copper. One example of this class of implements, or personal decorations, obtained from the Lockport mound, and now in the possession of Mr. Merrin, measures 5·30 by 3·80 inches.
