In 1940 Evadene Burris Swanson earned her doctorate in history at the University of Minnesota. Her dissertation, published now for the first time in book form, offers a vivid look at how the abundant wildlife of the frontier nurtured and sustained the American Indians and the settlers from the east. The importance of her work was recognized in the forward by Aldo Leopold, author of the landmark conservationist book Sand County Almanac, who wrote, "quite aside from the scientific value of wildlife history, (the dissertation) has a cultural value which will one day amply repay the labor of collecting and the cost of preserving it. . .I hope for its early publication, in order that I and my students may have the benefit of the rich and varied treasures of information which she has dug out of Minnesota's attic."
