HISTORY.

My survey of the grounds occupied by the aboriginal ruins in the valley of the Pecos indicates, as I have already stated, three epochs, successive probably in time, in which they have been occupied by man; that is, I have noticed these, and beyond these I have not been able to go as yet. Subsequent explorers may be more fortunate. This distinction, or rather classification, is very imperfect in the two earlier stages, and even arbitrary; but between the second and the last there is a marked break,—not in time, but in ethnological development. I shall term the three epochs as follows:—

1. Pre-traditional. (Indicated by the presence of the corrugated and indented pottery as its most conspicuous "land-mark.")

2. Traditional and documentary. (Documents in the sense of written records.)

3. Documentary period.
