DAGGER: A long sharp-pointed blade of [flint] (or a copper pin) presumably hafted with a wooden handle, used as a hunting knife or in hand-to-hand fighting.
DARTHEADS: Medium-sized weapon heads (2½ to 4 inches long) presumably used to tip lances or javelins.
DICKSON MOUND: A [burial mound] near Lewistown in Fulton County where some three hundred skeletons together with their grave offerings have been exposed to view. It is now a State Park and open to visitors.
DIGGING STICK: A conveniently-shaped stick used by primitive peoples in collecting tubers and roots and small animals, digging storage pits, and for preparing the soil for planting. Antler was sometimes shaped and presumably employed in like manner.
DIGGING TOOL: Any implement employed by primitive peoples in digging—a [digging stick], a shell hoe, or a chipped [flint] hoe.
DOMESTICATION: The breeding and rearing of plants and animals under man’s control and for his needs.
DRIFT (rarely drifter): A blunt tool of antler or bone presumably held in the hand and pressed against a [flint] to flake it, or one held against the flint piece and struck with a hammer for a like purpose.
DUGOUT: A boat made by hollowing out a log with fire and tools and shaping its exterior suitably for water travel.
ECONOMIC ASPECT: That division of primitive [culture] concerned primarily with securing and preparing food, shelter, clothing, and raw materials for tools, weapons and other material devices, and the technologies involved. This required considerable knowledge of natural resources, properties of materials, and lay of the land and permits freer direct creative intellectual effort than does any other aspect.
ECONOMY: The chief means of securing food and other basic physical requirements of man, as a hunting-collecting economy.
