The only specific reference to the Wisconsin region is on page 249: "One of the most fascinating of the Burial Mound farmers were the Effigy Mound people of the northern Mississippi region. Centering in the present state of Wisconsin, a group of Moundbuilders left behind them some thousands of distinctive mounds in the outlines of birds, animals, and occassionally of men. Often mixed in the groups and clusters of effigy mounds are plain conical and bar-shaped tumuli patently built by the same people. All of these were burial monuments as their contents testify. Under the effigy mounds, the builders had buried the remains of their dead. The graves were peculiar in that the bodies had been exposed elsewhere until the flesh disentegrated. The the bones were buidled together and placed in a disarticulated pile and the mound raised over them. With the burials of the effigy mounds are copper ornaments and other offerings although these are less spectacular that those of the Hopewell Moundbuilders."
