Original (which is almost certainly a carbon copy) is in the Northern Great Lakes Center Area Research Center, Ashland. Call Number Northland SC 26. Another document at the Center (Northland SC 10), by John McCormick, presented as a paper in a Rural Sociology class at Plattville State Teachers College, c. 1950, is copied, almost word for word from Mrs. DeWitt's paper, and will not have a separate bibliography entry.
