HOW MARBLES ARE MADE.
Most of the stone marbleß used by the boys are made in Germany The refuse only of the marble and agate quarries is employed, and this is treated in such a way that there is practically no waste. Men and boys are employed to break the stone into small cubes, and with their hammers they acquire a marvellous dexterity. The little cubes are then thrown into a mill, consisting of a grooved bedstone and a revolving runner. Water is fed to the mill and the runner is rapidly revolved, while the friction does the rest. In half an hour the mill is stopped, and a bushel or so of the perfectly round marbles taken out. The whole process costs the merest trifle.
