Note 81 — Chapter I

Dr. Rau has shown that division of labor and its advantages was recognized among the aborigines; that certain individuals who were qualified to manufacture particular implements devoted themselves exclusively to that work. He bases his conjecture “on the occurrence of manufactured articles of a homogeneous character in mounds or in deposits below the surface of the soil. There is little doubt, for instance, that there were persons who devoted their time chiefly to the manufacture of stone arrow-heads and of other articles produced by chipping, among which may be mentioned those remarkable large digging tools described by me several years ago, and the oval or leaf-shaped implements made of the peculiar hornstone of ‘Flint Ridge’ in Ohio.” See Stock-in-trade of an Aboriginal Lapidary, by Charles Rau, Smithsonian Report for 1877.
