were ordinarily employed for baking corn-cakes and frying meat; but it does not anywhere appear that ornamental stone plates were in general use."[137] This specimen, or one identical with it, is in the possession of the Natural History Museum in New York. It was plowed up in 1859 on the lower terrace of a large mound near Cartersville, Ga. Other specimens somewhat similar to the one described by Professor Jones have been obtained from the same region, two of which are now in the National Museum. One of these from a mound on the Warrior Riv. is made of gray slate, and is about eight inches in diameter. It is smooth, symmetrical, and doubly convex. There are three shallow, irregular lines near the border, and the periphery is ornamented with twenty-one scallops. Another specimen, a cut of which has already been published by Dr. Rau in "The Archæological Collection of the National Museum," p. 37, is illustrated in Plate LVII, Fig. 1. It is nearly one-half an inch in thickness, and about ten inches in diameter. A single incised line runs parallel with the circumference, which is ornamented with nine rather irregularly placed notches. The stone disk, of which an outline is given in Fig. 2, Plate LVII, was obtained from the Lick Creek mound, in East Tennessee. Its resemblance to the shell disks is so striking that it must be regarded as having a similar origin if not a similar use. The division into zones is the same as in the shell disks; the outer is divided into twelve lobes, and the cross in the center takes the place of the involute rosette with its central circle. The fact that this particular design is engraved on heavy plates of stone as well as upon shell gorgets is sufficient proof that its origin cannot be attributed to fancy alone. I have seen at the National Museum a curious specimen of stone disk, which should be mentioned in this place, although there is not sufficient assurance of its genuineness to allow it undisputed claim to a place among antiquities. It is a perfectly circular, neatly-dressed sandstone disk, twelve inches in diameter and one-half an inch in thickness. Upon one face we see three marginal incised lines, as in the example just described, while on the other there is a well-engraved design which represents two entwined or rather knotted rattlesnakes. An outline of this curious figure is given in Plate LXVI. Within the circular space inclosed by the bodies of the serpents is a well-drawn hand in the palm of which is placed an open eye; this would probably have been omitted by the artist had he fully appreciated the skeptical tendencies of the modern archæologist. The margin of the plate is divided into seventeen sections by small semicircular indentations. This object is said to have been obtained from a mound near Carthage, Ala. The reverse is shown in Fig. 4, Plate LVII. A similar specimen from a mound near Lake Washington, Mississippi, is described by Mr. Anderson.[138]
