No rock smaller than one-half the size of a man's fist should be put into the kiln, as the small pieces will tend to stop the draft; and no pieces much larger than the size of the two fists should be used, as the very large rocks will not be burned through entirely.

The coke should be of open grain, and at the same time be fairly compact, for then it will hold its heat during the required time to give the best results. The coke should be free from sulfur, as there is a possibility of sulfuretted hydrogen being generated, which, when carried into the carbonatation tanks, might do considerable harm. The importance of care in addition of lime to the juices cannot be , and, if the liming is not done according to the various rules that have been applied only after years of experience, the succeeding operations will prove failures and the final product will be of little value as a marketable commodity. The changes which take place during the carbonatation are both mechanical and chemical. In the chemical nature, the lime forma compounds with the sugar and the impurities present in the juice. Some of these compounds are of complex combination, while others are very simple in their composition. The gas.—The gas which is produced in the kiln and pumped into the tanks of this first carbonatation station has a great affinity for the lime, breaking up the compound it forms with the sugar and form- ing an insoluble lime carbonate, thus setting the sugar free and leaving it in solution in the juice. The gas is pumped into the tanks through pipes which extend to the bottom of the tanks and are there divided into three .sections. From each of these sections it pa
