Anyone ever read The Squaw by Bram Stoker?

This question is in reference to the sidestory that was told by the American tourist to the young couple. He mentioned a "half-breed" (I ume he meant half Native American, half Caucasian) whom they called Splinters because of something he did to a Squaw's papoose. I have read the page numerous times, and can not understand what exactly he did to earn the nickname (though from the context, I gather it was something horriffic). Can someone please shed some light on this subject? Thank you!
