Read it through once

It is thought that they do not now steal many diamonds successfully. They used to swallow them, and find other ways of concealing them, but the white man found ways of beating their various games. One man cut his leg and shoved a diamond into the wound, but even that project did not succeed. When they find a fine large diamond they are more likely to report it than to steal it, for in the former case they get a reward, and in the latter they are quite apt to merely get into trouble. Some years ago, in a mine not owned by the De Beers, a black found what has been claimed to be the largest diamond known to the world's history; and, as a reward he was released from service and given a blanket, a horse, and five hundred dollars. It made him a Vanderbilt. He could buy four wives, and have money left. Four wives are an ample support for a native. With four wives he is wholly independent, and need never do a stroke of work again.
