2308 The Making of the Two Dakotas, by Helen Graham Rezatto (read 16 Jul 1990) This is a very unscholarly book, but told interesting little things about events in the Dakotas before 1890. The most interesting thing about the book is that it cites the thesis of Elmer Cwach, my brother-in-law, A History of the Yankton Indian Agency during the 19th Century, University of South Dakota, 1952.
