"It seems so when you see it in figures, doesn't it?" returned the superintendent. "Next to the United States in sugar consumption comes England, the reason for this being that the English manufacture such vast amounts of jam for the market. England is a great fruit growing country, you must remember. The damp, moderate climate results in wonderful strawberries, gooseberries, plums, and other small fruits. With these products cheap, fine, and plenty, the English have taken up fruit canning as one of their industries, and they turn out some of the best jams and marmalades that are made." The boys listened intently. "The Germans and the French are much more frugal than we Americans," went on Mr. Hennessey. "Sugar is not so common in their countries. Often when in Germany you will notice people in the restaurants and cafés who carry away in their pockets the loaf sugar which has been allotted them and which they have not had occasion to use. It is a common occurrence, and considered quite proper, although it looks strange to us. Doubtless, too, if you have traveled abroad you have discovered how few candy shops there are. Foreigners regard the wholesale fashion in which we devour sweets with wonder and often with disgust. They consider it a form of self-indulgence, and indeed I myself think we are at times a bit immoderate." "My father says we are an immoderate people," Van put in. "I am afraid he is right," nodded Mr. Hennessey. "We seem to proceed on the principle that if a thing is good we must have a great deal of it. However, the vice--if vice it be--is good for the sugar business." He paused a moment and stood looking down into the great foaming vats before him. "You can't see the steam coils that are melting this raw sugar," he remarked. "They go round the inside of the tanks. But after the liquid is drawn off you can see them. When first melted the sugar is far from pure; you would be astonished at the amount of dirt mixed with it. Many of these impurities boil up to the surface and over and over again we skim them off. But even after that we have to wash the sugar by various processes. After it has been separated, clarified, and filtered it comes out a clear white liquid, and is ready for the vacuum pans, where the water is evaporated and the sugar crystallized." "How do you get the liquid clear?" asked Bob. "After it has been skimmed as carefully as possible we first settle it through the agency of chemicals," answered Mr. Hennessey. "We use milk of lime as a foundation, but we put other things with it. Our exact formula is a secret, but since you are in the family I guess there would be no objection to my telling you that we use---" "Don't tell us! Don't tell us!" cried Van suddenly. "I don't want to know. I'd rather not. I mustn't listen." Covering his ears the boy turned away. His companions regarded him with amazement.
