A few words regarding the illustrations. An inspection of all the figures in this chapter, marked from the Hopewell Group, give some idea of the remarkable copper effigies, ornaments, cut designs, etc., comprising the Hopewell collection. This is now on exhibition in the Field Museum of Natural History, Chicago, and can be seen by any person who will take the pains to visit that institution. It is justly considered the greatest prehistoric copper collection in the United States. In the Hopewell Group altars hundreds and hundreds of copper ear ornaments were found, all more or less affected by heat. Professor Mills has dug up many ornaments of these same kinds and says of them:— “Copper ear ornaments were frequently met with in the graves, and twenty specimens were secured. They were invariably found in pairs. The manufacture of these ornaments required skill, as well as a high degree of advancement in ornamental art. The mode of manufacture of the ear ornaments, although two different types were found, was similar. One type was made of two concavo-convex plates, and were connected by a cylindrical column; but only a few pairs of this type were found. The other type, which was most common, was made of four plates of copper, two of which are circular, and two concavo-convex. The concavo-convex plates are attached to the circular pieces, which form the inside of the ornament. The discs are connected with a small cylinder of copper. This figure is a good illustration showing two views of the second type of ear ornaments. Other copper ornaments were found sparingly in the burial cists. From one grave a large copper crescent was removed, and from another, six large copper balls.” Sometimes the copper plates were highly ornamented and cut or trimmed. Fig. 610 is thus described by Professor Mills:— “The plate shown in this figure is perhaps the heaviest and smoothest of all the plates taken from Seip Mound. The scroll pattern cut upon one side of the plate represents the first specimen of the kind taken from the mounds of Ohio, as far as known. The plate was wrapped in leather when it was placed in the grave, and portions still adhere to the plate, as shown in the cut.” Of the interesting pendants in sheet-copper, Fig. 617, exhumed from a mound in Moundville, Alabama, Mr. Moore has to say:— “The upper part of the pendant has parts excised to form a six-pointed star within a circle. On the body of the star, _repoussé_, is a symbol to which we shall revert later. Below is an excised triangle; beneath which is part of an arm encircled by a string of beads and an extended hand bearing on it the open eye, all _repoussé_.”
