I'm like y'all. I do not remember reading very much about a slaves insurrection or attempts to poisen people. I do remember hearing of the one woman, I think in St Francisville, La, using Oleandar in a cake. She intended to make the woman and children sick according to one version so they would feel they needed her when she got them well. Another version said the husband caught her listening at a doorway and he cut off her ears and she was trying to poisen him. That's the only poisen story I've heard. I believe they said the other slaves caught her when she tried to run because if she had gotten away they'd be in worse trouble. She was hung.
Truth be told, I've read little on real facts to back up any cruel and harsh treatment but I'd imagine it existed. If there were more trying to poisen the whites, maybe there's more to the beatings and lynchings than just meanness.
So there was a tax on the Chinese workers? I did not know that either. Did the railroads pay it or was it just in one area? Hmm, don't know.
Reading the reports on the Indian activity sounds like the old Saturday morning tv programs. Very interesting take on it from the non-Native side.
