Good find.
I don’t know how many of you actually read the article, but it is worth studying. It is quite different from any of the history (or natral history) that we learned in school. For one thing, we were never taught that the Indians actually deliberately burned off the forest and grasslands from time to time. In fact, this is the second time in 2 weeks that I’ve encountered that little taught fact. As school kids, we were always taught that pre-history forest fires were caused by lightning.
