As we have seen in the early modification of food utensils the beginning of the art of cutting and shaping shell, which in time led to the manufacture of objects of taste, and probably proved an important step in the evolution of native American art, so in this convenient and workable material, as employed in the mechanical arts, we witness the inception of many important human industries, and in the rude machines constructed from shell probably behold the prototypes of numerous works in stone and metal. It cannot be supposed that such of these objects as we do possess are of very ancient date, as the material is not sufficiently enduring. It is also improbable that such objects would, as a rule, be so frequently deposited in graves, as food vessels or objects of personal display, and objects not so deposited must soon have disappeared. The early explorers of the American coast make occasional mention of the employment of shells in the various arts. As many of these notices are interesting, and have an important bearing upon the subject under consideration, I will present a number of them here. Among a majority of the American Indians, knives of stone, obsidian, jasper, and flint were in general use, but it would seem that shells artificially shaped and sharpened were also sometimes used for shaping objects in wood and clay, in preparing food, in dressing game, and in human butchery. Strachey informs us, in volume VI of the Hakluyt Society, that when the omnipotent Powhatan "would punish any notorious enemy or trespasser, he causeth him to be tyed to a tree, and with muscle shells or reedes the executioner cutteth off his joints one after another, ever casting what is cutt off into the fier; then doth he proceede with shells and reedes to case the skyn from his head and face."[30] Such knives were also used by Powhatan's women for cutting off their hair.[31] A number of authors mention the use of shells as scalping-knives. Kalm, speaking of the Indians of New Jersey, says that "instead of knives, they were satisfied with little sharp pieces of flint or quartz, or else some other hard kind of a stone, or with a sharp shell, or with a piece of bone, which they had sharpened."[32] The Indians encountered by Henry Hudson during his first voyage, in making him welcome, "killed a fat dog, and skinned it in great haste with shells which they had."[33] Beverly asserts that before the English supplied the Virginia Indians with metallic tools, "their Knives were either sharpen'd Reeds, or Shells, and their Axes sharp Stones bound to the end of a Stick, and glued in with Turpentine. By the help of these they made their Bows of the Locust Tree."[34]
