These numerous and widely varying factors make it very difficultto strike an average for the cost of producing high-grade SouthCarolina phosphate, but the following figures, compiled from dataobtained in these fields and from the authors own observation, areprobably as close approximations as can be obtained.

In mining and preparing South Carolina rock for the market thesame sources of waste are encountered as in the production of Floridaphosphate. The loss of finely divided phosphate (held in suspensionand passing through the cylinder screens) incident to the presentmethod of cleaning the rock is very great, though not as great propor-tionally as the loss in washing the Florida The phosphatestratum w
