"And then?"
"Then follows crystallization, and this too requires skilled workmen and extreme care. The water is evaporated and the sugar crystallized in the vacuum pans, the size crystal depending upon the temperature at which the liquid is boiled. It takes a lower temperature to form a small crystal and a higher one to form a large crystal. An expert who takes the temperature of the boiling sugar regulates what we call fine-grain or coa.r.s.e-grain sugar by regulating the size of the crystals. By drawing off some of the liquid and examining it on a gla.s.s slide by electric light he can tell the precise moment at which the crystals are the right size. Each size has a name by which it is known in the trade: Diamond A; Fine Granulated; Coa.r.s.e Granulated; Crystal Domino; Confectioners" A and so on."
They were walking as Mr. Hennessey talked. "After the sugar has been crystallized in the pans it pa.s.ses into a mixer, where it is stirred and kept from caking until it is put into the centrifugal machines, which actually spin off the crystals. These machines are lined with gauze, and as they whirl at tremendous velocity they force out through this gauze the liquid part of the sugar and leave the sugar crystals inside the machine. When these are quite dry the bottom of the receptacle opens, and the granular sugar is dropped through into a large bin."
"But I should think it would stick together," objected Van.
"That"s an intelligent objection, my boy," declared Mr. Hennessey, much pleased at Van"s grasp of the subject. "It would stick if it were not dried off by a degree of heat just right to keep the particles separate and not allow them to cake. After this any dust or dirt adhering to the sugar is blown off by an air blast. The product is then ready to be pressed into moulds or cut; boxed in small packages of varying weights; or put into bags or barrels."
Mr. Hennessey led the way to another floor of the refinery.
[Ill.u.s.tration: "I SHOULD THINK IT WOULD STICK TOGETHER."]
Here were automatic machines upon which empty boxes traveled along until they reached a device that filled each one with the exact number of pounds to be contained in it, the package afterward pa.s.sed to women who sealed it tightly and gave it the final touch before it was shipped. Other women were packing loaf or domino sugar, while down-stairs in a cooper shop men moved about constructing with great rapidity the barrels that were to carry larger quant.i.ties of sugar to the wholesale and retail stores.
"I guess by this time you"ve had all the sugar-making you want for one day," declared the superintendent. "I"m afraid I"ve given you quite a stiff lesson. You see I am so interested in it myself that I forget to have mercy on my listeners."
He smiled down at the boys.
"I"m sure we have had a fine morning with you, Mr. Hennessey, and we certainly have learned a lot," Bob said, putting out his hand. "I can"t swear, though, that we could make white sugar even now."
"Faith, I"d be sorry if I thought I could teach any one the whole process in three hours. It would make my twenty years of study and hard work brand me as pretty stupid," chuckled the big superintendent.
CHAPTER VI
A FAMILY TANGLE
It was not until the boys were in the motor-car and returning home that Bob ventured to mention to Van his strange behavior of the morning.
"What on earth was the matter with you, Van?" he asked.
Van stirred uneasily.
"Bobbie," he said, "I"m going to tell you something. I"ve been wondering whether I"d better or not, and at last I"ve decided to. I didn"t want to go to your father"s refinery to-day or, in fact, at all. You"ve all been very kind to me, although it was not until I got a letter from my father this morning that I realized how kind."
He paused.
"Has your dad told you anything about my people?" he asked abruptly.
"Of course he knows, but he may have thought best to keep it to himself; at any rate it has not prevented him from giving me as cordial a welcome to your home as he would if--"
"If what?"
"Well, if I weren"t the person I am."
"What do you mean?"
"Why, he"s trusted me and treated me as if he really liked me; and yet under the circ.u.mstances you can"t expect him actually to mean it."
"Mean what? What are you talking about?"
"Hasn"t he spoken to you about my father?"
"Of course not; why should he?"
"Then you haven"t heard anything?"
"Not a word. I don"t understand what you are driving at at all," Bob declared, somewhat irritated. "Out with it. What"s the matter?"
Van hesitated as if uncertain how to begin.
"That"s mighty white of your father," he murmured, breaking the pause. "You see, it is this way. When I wrote home that I was going to New Hampshire to visit my roommate the family wrote me to go ahead. I recall now that I didn"t mention your last name; in fact I guess I haven"t in any of my letters. When I did happen to write (which wasn"t often) I"ve always spoken of you as _Bob_. So when I got to Allenville I dropped a line to Father to say I"d arrived safely and in the note I put something about Mr. Carlton.
Father lit on it right away; he wished to know who these Carltons were. I replied they were Mr. and Mrs. Carlton, of course--the parents of my roommate. Upon that I got another letter from home in which Father inquired if your father was in the sugar business, and said that years ago he used to have a partner named James Carlton, who started in the sugar trade with him and with whom he later quarreled. He supposed this could not be the same person, but he just wondered if by any chance it was."
Van stopped.
"Was that all he said?"
"No, but I don"t like to tell you the rest, Bobbie."
"Fire away--unless it is something about Dad," Bob replied. "If it is I shan"t listen, or at least I shan"t believe it."
"It isn"t exactly against your father. I do not understand it very well myself. My father just said that if your father was Mr. James Carlton and he was in the sugar business he felt that because of family misunderstandings it would be better if I did not visit here again. He was very sorry I had done it this time, but of course that could not be helped now."
"You don"t mean to say he wants you to break off your friendship with me?" Bob gasped tremulously.
"No, he didn"t seem to be opposed to you; he just was hot at your dad. He added that he didn"t believe your family could have known who I was when they asked me here, and I am afraid that"s true, Bobbie."
"Why, of course they knew! Haven"t I spoken of you over and over again?" Bob protested indignantly.
Van shook his head.
"They knew I was your chum all right, Bob; but so far as details were concerned your family did not know much more about me than mine knew about you. Don"t you recall how, when I arrived at Allenville, your father asked if I was one of the _Sugar Blakes_--Asa Blake"s son?"
"Yes, I do remember that now, but--"
"That, you will recollect, was after I was landed at Allenville and your guest. Your father didn"t know until that moment who I was, and when he found out he was too decent to say anything, or make it evident he didn"t want me in the house. What could he do?"
"But--but--"
Bob broke off from sheer inability to continue. He was much too bewildered.
"Your father sensed the awkwardness of the situation at once. Here you had gone to school and as ill luck would have it you had picked from out the entire bunch of boys the son of his worst enemy for a chum. Neither your father nor mine realized the truth until you innocently carted me home with you for a holiday visit. When your father found out the fact he was too polite to turn me out-of-doors; he just acted the gentleman and made the best of a bad dilemma,"
explained Van with appalling convincingness. "He even had the goodness to save my life the day we got lost on one of your New Hampshire mountains. He didn"t tell you any of this because he didn"t want to spoil your pleasure; but I am certain that if he had known who I was before I came he would not have allowed you to ask me into your home."
"Nonsense! You are way off. Why, he"s been as interested in having you with us as I have; at least he has acted so."
