Richard Schultes: I never had any problems with Indians. The Indian in the Colombian Amazon — and I suppose everywhere else, until he is civilized — is a wonderful person. If he likes you — and I guess they liked me, and I liked them — if you act as a gentleman among these people, they are gentlemen. I was with them all the time that I worked there, because we had very few European-type people going down into that part of the Amazon. It’s not easy to get around because of rapids, and waterfalls, and lack of air service and so forth.
