When I was 24, I took a year off (discharged from U.S. Army 10/56). Interested in birds, I called up the Museum of Natural History to volunteer as an expedition assistant. NO. But a month later they called--an assistant had dropped out. YES. So 2 months in the Museum creating labels and the like, and 3 months on a schooner collecting marine life and island fauna & fossil specimens off Baja California and in the Sea of Cortez! Having learned how to type in the Army, I transcribed my Journal and added photographs. Index has listing of scientific papers written from the expedition collections.
Than, I was invited to be an assistant on a trip to Huautla and other native-American towns in Mexico with Gordon Wasson to seek the sacred mushroom! Again I kept a Journal and saved the photographs I took. The Index lists selected articles and books by R. Gordon Wasson, and also Richard Evans Schultes, such as the Golden Guide to Hallucinogenic Plants, and with Albert Hoffman "Plants of the Gods: Origins of Hallucinogenic Use".
