I bought an updated copy of probably the best history of the Kansa. While the writing style is rather academic and dry in the beginning, it improves, particulary when Unrau quotes from contemporary sources. One example occurs when describing Kansa living conditions on page 37.
"The obvious lack of family privacy apparently did not bother the Indians, but it left an indelible impression on some white visitors. The Reverend Isaac McCoy complained in 1828 that 'half the village' appreared to crowd into the lodge assigned to him; children cried without interruption, adults screamed wildly, and the air was so saturated with smoke from the fireplaces and tobacco pipes that he was forced to punch a hole in the wall in order to breathe."
