...I'm currently reading "Cannibalism, Headhunting and Human Sacrifice in North America" by Feldman (and he doesn't limit himself to the Indians, either!). There's a history of the pox and another on the history of vice in London waiting in the wings, along with Utley's book on the first century of the Texas Rangers.

I just read this thread today, for the first time. But I picked up the Utley book on the Texas Rangers in a yard sale this past Saturday, and am about 2/3 of the way through it now.
