to describe as the Civilized Nations. There is not a savage people between Anáhuac and Nicaragua that has not been influenced in its institutions by intercourse, warlike, social, or commercial, with neighbors of higher culture, and has not exerted in its turn a reflex influence on the latter. The difficulty of drawing division-lines between nations thus mutually acting on each other is further increased in America by the fact that two or three nations constitute the central figure of nearly all that has been observed or written by the few that came in actual contact with the natives. This volume will, therefore, deal rather with the native civilization than with the nations that possessed it.

In this general view I shall avoid all discussion of disputed questions, reserving arguments and details for future volumes on antiquities and aboriginal history.

Not that these are definitely drawn boundaries, but outside of these limits, disregarding the New Mexican Pueblo culture, this civilization had left little for Europeans to observe, while within them lived few tribes uninfluenced or unimproved by contact with it. No portion of the globe, perhaps,
