The Aborigines of Minnesota 1906
Mr. R. M. Van DeVoort gave information concerning the exploration of a mound of this group about the year 1885. The bones were about 3 ft. from the surface and consisted of six skeletons, each skeleton occupying a space about 18 inches by 30 inches. The lower jawbone was large, the teeth, so far as found, all double, the brow considerably receding backward, thigh-bone 22 inches long, upper arm-bone 14 inches long. These bones were taken to Chicago by a doctor some five years after they were discovered.
