have a chance at the sun, it is washed in enormous mills, and reduced in the proportion of one to four million: that is, for every pound of diamonds found, four million pounds of blue dirt are mined, hoisted, exposed in the field a year, and then run through the washing-mills. . . . In these washing-mills, the blue dirt is first crushed between rollers, and then run through shaking washing-pans three different times. What is left is then taken in cars to another mill, called the pulsator, and here the precious dirt is again washed three times. Finally the diamonds and the heavier pebbles remaining after six washings, go in a stream of water over a shaking-pan, the bottom of which is covered with vaseline. The diamonds stick to the vaseline, for some reason yet unexplained, while the pebbles roll away with the water. The diamonds on the screen are then easily collected and sorted. Some of the sorters, greatly to my surprise, were negroes in charge of white men. . . . Today I saw the result of one day's washing from one mine; a pile of rough diamonds, many of them as small as pin-heads. One of them was said to be worth a thousand dollars. Dozens were of fairly good size, but the bulk of them were very small. These small diamonds will be used in cutting the big ones. There were many straw-colored diamonds, and some of them were black; the black ones will be used in diamond drills. It seemed to me that there were half a pint of these diamonds; Adelaide says a pint. But anyway, three or four thousand men, aided by the most enormous machines I have ever seen, work a day, and turn out—what?
