This excerpt is from Adventures of Huckleberry Finn by Mark Twain
We busted it up, and chased the children up the hollow; but we never got anything but some doughnuts and jam, though Ben Rogers got a rag doll, and Jo Harper got a hymn-book and a tract; and then the teacher charged in, and made us drop everything and cut.
I didn't see no di'monds, and I told Tom Sawyer so. He said there was loads of them there, anyway; and he said there was A-rabs there, too, and elephants and things. I said, why couldn't we see them, then?
I have no idea what "di'monds" means. I thought it was a typo, but all copies on the internet use the same spelling. Is it no different from "diamonds"?
