The present publication proposes to bring before the public, in popular form, some scientific results obtained while studying the language and ethnology of the Creek tribe and its ethnic congeners. The method of furthering ethnographic study by all the means which the study of language can afford, has been too little appreciated up to the present time, but has been constantly kept in view in this publication. Language is not only the most general and important help to ethnology, but outside of race, it is also the most ancient of all; ethnologists are well aware of this fact, but do not generally apply it to their studies, because they find it too tedious to acquire the language of unlettered tribes by staying long enough among them.
