In every instance (except that of the chambered mound at Douglas) where these implements were found in mounds they were placed quite superficially at the summit of the mound; indeed at Benque Viejo, Seven Hills, and Santa Rita it seems probable that they had not been buried originally at all, but merely placed upon the summit of the mound and in course of time became covered with a layer of humus from decaying vegetation in the vicinity. [Illustration: FIG. 49.--Flint objects from Tennessee.] Similar flint objects have been found in other parts of the world, notably at Brionio in Italy and in Stuart, Smith, and Humphrey Counties, Tennessee. In figure 49, _b_-_n_, are shown somewhat rough outline sketches of the Tennessee objects, and in figure 50, _a_-_p_, are represented a selection of the most important objects found at Brionio, now in the collection of the late Professor Giglioli at Florence. The Tennessee objects are to be seen at Washington. The latter are small when compared with the largest of the Maya specimens, but are neatly chipped, whereas the Brionio objects are very crudely blocked out, mostly from black flint. It will be observed that figure 49, _c_, _d_, _g_, from Tennessee, shows specimens almost identical with figure 50, _p_, from Brionio, and with the turtle, pictured in plate 15, _g_, from the Douglas chambered mound; again the spiked crescents, figure 50, _b_, _c_, _n_, from Brionio, closely resemble the very much larger spiked crescent illustrated in plate 15, _e_, from the Douglas chambered mound, and still more closely the spiked crescent figured in "Flint Chips" (from Wilson, Prehistoric Man, op. cit., p. 214). Though these objects are not found in Central America outside the Maya area, the Aztec were sufficiently expert in the art of flint and obsidian chipping to have produced them had they wished. In figure 49, _a_, is seen the outline of a type of labret worn by the Aztecs, chipped out of both flint and obsidian, which compares favorably in workmanship with any of the objects from the Maya area. In reviewing the evidence it would appear that these eccentrically shaped objects were not employed either as implements or as weapons, most of them being utterly unsuited in both size and shape for such purposes; moreover, none of them show any signs of wear or use. Neither were they used as ornaments, as many of them are too large and heavy, while the more roughly chipped specimens would be quite unadapted for such a purpose. Judging by the fact that 5 at least of the 11 separate finds wore associated with human burials, it seems probable that these objects were purely ceremonial in use; that they were most frequently, if not invariably, buried with the dead, either on top of the sepulchral mound, in close association with the corpse, or by the side of a memorial stela; and that they were manufactured and used solely for this purpose.
