This bulletin is the third in a series of six, recounting the field work done among Wisconsin Indians to discover their present uses of native or introduced plants and, insofar as is possible, the history of these plant uses by their ancestors. As far back as 1888 Hoffman[85] reported that the medicinal lore of the Ojibwe would soon be gone. But thirty-two years later, it is still partially recalled and practised among the more primitive bands of these people. How long it will persist is problematical. The Ojibwe are the most numerous of any of our tribes and as long as they live in the northern forest and lake district of Wisconsin, so long will the older Indians continue to explain the natural history of their environment to the young men and women of the tribe. The writer deplores the brevity of the time that could be devoted to each tribe, and applauds the similar study reported by Miss Frances Densmore[86] in her fifteen years of research among the Ojibwe. Necessarily the most valuable information comes from the oldest Indians, and many informants have died since this study was made....
