"I should have thought Mr. Burns would have come himself," the man said; "you are young for this work, aren't you?" Hamilton flushed at this reference to his boyish appearance, but he answered steadily: "Yes, sir, I believe I am younger than most of the assistant special agents, but I have had a good deal to do with figures." "Burns is a good man," the manager continued. "If the government has men of that stamp all over the country, the statistics will be invaluable. You know Mr. Burns?" he added suddenly. "Only just since this work began, Mr. Arverne," the boy replied. "Queer chap. I don't believe he eats a bit of food or drinks a glass of water without mentally figuring the nutritious percentage in the food, and the effect of his drink upon the water supply of the world." Hamilton laughed. "He is a little that way, sir," he said. "A little!" the manager exclaimed. "But to return to the point. You didn't tell me why Mr. Burns didn't come himself." "He said that the office work was piling up, sir," answered the boy, "and--if you don't mind my saying so, Mr. Arverne--he spoke of it as an opportunity for me, since it was the largest plant in the city and my schedules had been the most complete of those turned in to him." The manager eyed the boy keenly. "Mr. Burns doesn't make many mistakes," he said, after a moment, "and if he has confidence in you, he knows what he is talking about. This is a country of young men anyway, and it seems to be getting younger all the time. Where is the schedule?" Hamilton handed him the paper and sat back, waiting. Several minutes passed, while the manager went over the questions item by item. "Yes," he said at last, "I think our books can answer every question there without difficulty. We keep very complete books. I am not so sure, Mr. Noble," he continued, "that I can give you those figures immediately in just exactly that form." "In what points do your books differ?" asked Hamilton quietly. "Not in any essentials, but in a few minor points," the manager replied. "For example, you want to know here the exact number of employees on our pay roll on December 15th. Now I could have the pay roll department--we keep it as an entirely separate department here--turn up instantly the payments for the week in which that date occurs, but in order to separate that one day from the week, reference will have to be made to the Employment Bureau to find out what workers left, and how many were added, and the day of the week on which each of these left or began work in that week, and to add or to deduct such sums from the weekly pay roll." "That difficulty has come up several times," said Hamilton, "because not many people pay their employees by the day. But in nine cases out of ten, an average for that week is usually struck, figuring in some cases by the days and in others by the hours. I suppose you noticed that the schedule itself states that what is sought is 'a normal day'?"
