This gives a revenue to the Griqualand Government of something over £2000 for every three months. About 1700 Kafirs are employed in the mine and on the stuff taken out of it at wages of 10s.* a week and their diet—which, at the exceptionally high price of provisions prevailing when I was in the country, costs about 10s. a week more. The wages paid to white men can hardly be estimated, as they are only employed in what I may call superintending work. They may perhaps be given as ranging from three to six pounds a week. The interesting feature in the labor question is the Kafir. This black man, whose body is only partially and most grotesquely clad, and who is what we mean when we speak of a Savage, earns more than the average rural laborer in England. Over and beyond his board and lodging he carries away with him every Saturday night 10s. a week in hard money, with which he has nothing to do but to amuse himself if it so pleases him.” * The equivalent of half a British pound
