Note 244 — Chapter XXV · ACCOUNT OF THE MANDAN INDIANS

Lewis and Clark describe this process of primitive bead-making, related to them by Garreau, the Arikkara interpreter, in Original Journals, i, pp. 272-274; see also Catlin, North American Indians, ii, p. 261. If the Mandan acquired this art from the Snake Indians, as tradition avers, their pounded glass was probably obsidian from the cliffs of the upper Yellowstone. See also Matthews, Hidatsa Indians, pp. 22, 23.—Ed.
