A third deposit was examined at _Eagle Hill_, in Ipswich, Massachusetts, situated on the borders of a creek, by which easy access is had to the sea-shore. The whole neighboring region consists of a series of low hills of gravel, some of them covered with boulders, but entirely destitute of forest trees. A few basswood trees (_Tilia Americana_) have been known to exist there within a few years, but otherwise those hills do not appear to have been wooded within the memory or traditions of the present inhabitants. Several shell-heaps are reported to exist in the neighborhood, but the only one examined was on the easterly side of the hill mentioned above. This consists of several disconnected deposits of shells, which are in part spread out into a uniform layer, but in a few instances form small knolls from eight to ten feet in diameter. Near the water’s edge the shells are exposed by the washing away of the bank, but elsewhere are covered with mould and turf, and, in some places, even on the knolls, with a layer of gravel. In the more even portions, this last may have been washed down from the slopes above, but such could not have been the case with the knolls, for the tendency would have been to denudation rather than to covering up. The shells, forming these deposits, are almost exclusively those of the common clam, which are still found here in great quantities, and yield a considerable revenue to those engaged in digging them. Large piles of recently dug shells may be seen along the neighboring shore, and noticeably contrast with those from the Indian shell-heaps, in being thinner and less rough in their texture. Shells of the oyster and the Mactra were found, but few in number. Somewhat extensive excavations[7] yielded bones of the deer, beaver, dog, birds, among these the bones of the turkey, and of fish; but only a single implement of stone, which was spherical in shape, with a groove around the middle of it. This was found by Mr. Putnam just beneath the surface. Some of the bones showed distinct marks of cutting instruments, and a few pieces of wrought bone were found, three of which are represented in Pl. 15, figs. 15, 16, 17. Two distinct fireplaces, indicated by hard-wood charcoal, ashes and blackened earth, were discovered resting on the earth and beneath the shells. V.
