The Zuni and the Arapaho Indians have a language with a complex grammar and copious vocabulary well adapted to the expression of the thoughts incident to their customs and status of culture, and they have no more difficulty in conveying their thoughts with their language by night than Englishmen have in conversing without gaslight.

Anthropology needs trained devotees with philosophic methods and keen observation to study every tribe and nation of the globe almost de novo; and from materials thus collected a science may be established.
