Until now no inquiries into the role of fungal hallucinogens in prehistory have ever dealt with the natives of North America. This has not meant that hard evidence was lacking: that evidence , though scant, has been accessible to any diligent seeker. To most it will come as a surprise to learn that natives of this land shared with the Eurasians the fly agaric (Amanita muscaria) practices documented in Musbrooms Russia and History (Wasson & Wasson 1957) and more fully in Soma. Divine Mushroom of Immortality (Wasson 1968). Only the role of the reindeer in the Siberian mushroom complex is perforce absent from the American usage. Evidence is available that indicates the Ojibway and some others of Algonkian linguistic stock living in the woodlands of this country and Canada consulted the fly agaric for divine guidance in their shamanic observances . This evidence will help in clarifying the ambiguities and murky passages of Siberian informants . May not our new testimony from the New World and the Siberian documentation, taken together, suggest a common ancestry in the remote past ? Just as in Siberia, here also there was use of the mushroom for its inebriating potency. We must not forget that north of Mexico most of our native population before the white man came possessed no alcoholic beverages and the only road to inebriation lay in ingesting plant hallucinogens, amongst which the fly agaric was conspicuous.
