Currently reading a kid’s history book about the Red Indians. Published in US in late 19th cent. On the basis that why not really, there’s some fun stuff to be found in the freebies on Kindle.
And I find out that wampum really was a thing, not just a movie line (“Heap big wampum!”). Sort of a worked sea shell, a little but not very like cowrie and used as money like cowrie. Also that everyone was very well aware that the Plains Indian lifestyle had been massively changed by the arrival of the horse, also that there was constant internal migration. Those claims of having been in a place forever are bunkum.
Finally, that there was a tribe called the Winnebagoes. I like that, out on the plains they were, following the buffalo in their RVs.
