[Illustration: Dart points of the shellheap dwellers were heavy, but workmanship varied from crude to very careful. Length, 2¼ to 2⅞ inches.] Our chief reminder of the presence of these early shell gatherers lies in the piles of shells which mark the scene of their activities. Of course the bones of deer, bear, rabbit, turkey, and other wildlife mixed with the shells show us that to vary their diet they did a good bit of hunting and fishing as well. The river and coastal shorelines are dotted with such refuse heaps, often of monumental size, from Florida to Louisiana and northward inland to the Ohio River and along the coast as far as Maine. It may be doubted that these were all produced by related peoples, or that they even represent the same time period; for it is certain that many of them were still growing in fairly recent years. Still, the fact remains that in the southern area as far north as Kentucky and Tennessee the sites represent the oldest camps yet to be uncovered following the earlier paleo-Indian period; and that besides the evidence of a remarkably uniform economy, they disclose a great similarity in the tools, weapons, and ornaments of their inhabitants. Projectile points (a term we use because “arrowhead” implies use of the bow and arrow) make up by far the most numerous type of artifact recovered; and these tend to be long and heavy, although proportions may be either narrow or broad. The size of these points indicates that instead of the bow and arrow the dart was used with the “atlatl,” the Aztec name we have adopted for the throwing stick or spear thrower. This is confirmed by the presence of many antler hooks for the end of the throwing stick. Shaped much like the hook of a giant crochet needle, these engaged the notched butt of the dart shaft. Additional evidence is found in the special stone, antler, or shell weights which were attached to the shaft to add momentum to the throw.
