Mound 21 of Group C was about 4 feet high and 50 in diameter. It proved to be made entirely of the sandy loam of the immediate vicinity. The remains of five skeletons were discovered at different points in the lower portion of the mound. The bones were nearly all reduced to dust, and only a fragment here and there could be saved. There was not a single relic found with the skeletons, and a few flint chips and a broken arrow-head were the only artificial objects found in the earth composing the mound. The condition of the bones showed considerable antiquity, but their advanced decay and friability were probably largely due to the character of the soil in which they were enclosed. The position of the skeletons rather goes to show that the several bodies were buried at different times, and that the mound was gradually constructed as the burials took place. For the present we are inclined to consider this mound, with some others in the valley, as a place of sepulcher by tribes of a more recent time than the builders of the earthworks of the Turner group. Mound No. 22 proved to be of a more interesting character than the last. This mound was 14 feet high and about 100 in diameter. It was composed of pure clay, except in the central portion. Five feet from the top there was found a hard mass of burnt earth and ashes, 7 feet deep and a little over 9 feet in width and length. Resting on top of this, about in the center, and covered in part by the overlying clay, lay a large stone celt. A foot below this, in the burnt material, was a stone implement perforated at its upper end. Below this, at points several feet apart, in the burnt mass, were three holes or pockets, each of which contained the remains of portions of human skeletons, surrounded by a thin layer of clay. Near the bones in the lowest pocket were three spear-heads or chipped points. A few potsherds and several flint chips were found throughout the burnt mass. Under it was a circular bed of black soil and ashes, 13 inches thick in the center and 14 feet in diameter, beneath which was a layer of fine sand and gravel, 3 inches thick, which covered another circular bed of black soil and ashes, 14 inches thick in the center and 15 feet in diameter. Directly under the center of this lower layer was a pit 4 feet deep and 10 feet 4 inches long, 4 feet wide at the ends and 3 feet 5 inches wide at the center. This pit probably had contained a wooden structure, as its sides showed rough striations, as if large logs had once rested against them. The pit had been dug in the drift gravel upon which the mound was built, and was nearly filled with soft, spongy ashes mixed with a reddish substance. Extended at full length at the bottom of
