Philological Note.—Three of these fifty-seven terms of Indian nomenclature are monosyllables, and twenty-four dissyllables. The latter are compounds, as in muk-wah (black animal), and wau-bose (white little animal); and it is inferable that all the names over a single syllable are compounds. Thus, aisebun (raccoon), is from ais, a shell, and the term past tense of verbs in bun.
