The author of this article, a vice president of J.P. Morgan & Co. Incorporated, together with his wife, Valentina P. Wasson, M.D., a New York pediatrician, has spent the last four summers in remote mountains of Mexico. The Wassons have been on the trail of strange and hitherto unstudied mushrooms with vision-giving powers. They have been pursuing the cultural role of wild mushrooms for 30 years. Their travels and inquiries throughout the world have led them to some surprising discoveries in this field in which they are pioneers. They are now publishing their findings in Mushrooms Russia and History, a large, richly illustrated two-volume book, which is limited to 500 copies and is now on sale at $125 (Pantheon Books, New York).
