I made sketches of two or three of the bone carvings, for the purpose of showing the art of the people who constructed this monument, so that by comparison with that of other known peoples some knowledge may be obtained, or theory advanced, concerning the race or tribe to which they belonged and the epoch in which they lived. Fig. 251 shows an exquisite bone carving of a paroquet which belongs much farther south and not found in that locality in modern times. The design shown in fig. 252 suggests a Mississippi Kite, but the zoologists of the Museum, while unable to determine with exactitude its intended representation, chiefly from the mutilated condition of the fragment, report it more likely to be the head of the "leather-back" turtle. Fig. 253 probably represents an otter with a fish in his mouth. [Illustration: PLATE 13. HUMAN SKULL WITH COPPER-COVERED HORNS. Hopewell Mound, Ross County, Ohio.

Moorehead, "Primitive Man in Ohio," Fig. XXXVII. Cat. No. 148662, U. S. N. M.] In trench No. 3, 15 skeletons (numbered 264 to 278, inclusive), were found on the base line, all extended. Objects of coal, bone, shell, or stone, had been placed with nearly all of them. Nos. 265 and 266 were laid on blocks of burnt earth 3 inches higher than the base of the mound. One of the skeletons in this mound (No. 248) is shown in pl. 13. It was a most remarkable specimen, and forms the frontispiece of Prof. W. K. Moorehead's volume "Primitive Man in Ohio," where it is described (p. 195) as follows: At his head were imitation elk horns, neatly made of wood and covered with sheet copper rolled into cylindrical forms over the prongs. The antlers were 22 inches high and 19 inches across from prong to prong. They fitted into a crown of copper bent to fit the head from occipital to upper jaw. Copper plates were upon the breast and stomach, also on the back. The copper preserved the bones and a few of the sinews. It also preserved traces of cloth similar to coffee sacking in texture, interwoven among the threads of which were 900 beautiful pearl beads, bear teeth split and cut, and hundreds of other beads, both pearl and shell. Copper spool-shaped objects and other implements covered the remains. A pipe of granite and a spearhead of agate were near the right shoulder. The pipe was of very fine workmanship and highly polished. [Illustration: Fig. 250. SPOOL-SHAPED OBJECT OF COPPER. Repoussé and intaglio decoration. Hopewell Mound, Ross County, Ohio. Natural size.]
