THE PRIMEVAL MONUMENTS OF PERU COM-
PARED WITH THOSE IN OTHER
PARTS OF THE WORLD.

BY E. G. SQUIER, M.A.*

THERE is a class of stone structures in Peru belonging to what is regarded through the world as the earliest monumental period, coincident in style and character with the cromlechs, dolmens, and "Sun" or "Druidical" circles, so called, of Scandinavia, the British Islands, France, and Northern and Central Asia. The existence of such remains. in Peru has not, I believe, been hitherto mentioned by any traveller in that country. They are not very numerous, at least not in the parts of Peru traversed by me, but their scarcity is probably in great part due to circumstances and causes to which I shall refer further on, and is by no means inconsistent with the supposition that they formerly existed in considerable, if not very great numbers.

I think students will attach importance to these remains as indicating the existence at one time or another in Peru of a population identical in degree and stage of development with the people who raised corresponding lithic and megalithic

Entered according to Act of Congress, in the year 1870, by the PEABODY ACADEMY OF SCIENCE in the Clerks Office of the District Court of the District of Massachusetts.
