Indians of Peru (with two plates)

The difficulty experienced in obtaining reliable information relative to conditions in general in the region about Iquitos, leads me to believe that the results of certain studies I have made regarding the Indians of Peru may be of some value and interest to others.
I had hoped to make a more thorough study of this interesting subject from actual observation among the different tribes, obtaining specimens of their weapons of warfare, their clothing, utensils, etc., but ill health has prevented any systematic work along these
lines. I have been fortunate, however, in having been able to make several trips among different tribes with Mr. George M. von Hassel, thus gaining first hand a limited amount of information on the subject, but the greater part conies from Mr. von Hassel himself, who,
it seems to me, is probably one of the best authorities on the subject and one highly qualified to speak regarding these Indians. Mr. von Hassel has had long experience in the interior of Peru. During the last ten or twelve years he has lived for months at a time with
various tribes, speaks the Quechua language and many other dialects, and by gaining their confidence has been able to mingle freely with the Indians, gaining an insight into their customs, methods, and manner of living such as few white men have enjoyed.
