The human head shaped out of flint is such as is occasionally found in Tennessee in the stone graves. Some similar heads are shown on a smaller scale, in Fig. 157, of Mr. Reeder’s collection. At the top to the left, in Fig. 160, are two of those problematical forms in flint which have so puzzled archæologists. These, together with the slender dagger-shaped objects of prodigious length, have for many years been listed under that opprobrious name, “ceremonial swords.” [Illustration: FIG. 158. (S. 2–3.) This illustration represents three animals and four birds, all chipped out of flint, and in the possession of H. M. Braun, East St. Louis, Illinois. ] The remarkable problematical forms in flint which have been called “stone swords,” shown in Figs. 161 and 162, deserve special mention. These are part of a series of forty-six flint implements which were found in Tennessee. I surrender the pen to Mr. W. J. Seever, former curator of the Missouri Historical Society Museum, who furnished the following description:— “On the banks of the beautiful Duck River, Humphreys County, Tennessee, near Painted Rock, on the farm of Mr. Banks Links, are the remains of an extensive, ancient, stone-grave cemetery, which at one time contained hundreds upon hundreds of stone cists. The land having been in cultivation for many years, wagon-loads of flat rocks used in building the graves have been carted off and the human remains scattered; innumerable objects of prehistoric art have been turned up by the plow and are now among the collections of the Ohio Valley.

(S. about 1–3.) From John T. Reeder’s collection, Houghton, Michigan. I know of few more remarkable finds in American archæology than this series of flint implements which were collected in Tennessee by Mr. Reeder. ]
