I met Don Juan in a rather fortuitous manner. I was doing, at the time
in 1960, I was collecting ethnographic data on the use of medicinal
plants among the Arizona Indians. And a friend of mine knew about Don
Juan. He knew that Don Juan was a very learned man in the use of
plants. And one day we happened to see him at the bus station. My
friend went and talked to him, and then he introduced me to Don Juan.
