"A man can get as much or as little out of being timekeeper as he chooses. Robert got a lot out of it. He formulated that summer a working theory of the length of time it should take to finish every detail of a building. He talked with bricklayers, he timed them and watched them, until he knew how many bricks could be laid in an hour; and it was the same way with carpenters, fireproofers, painters, plasterers. He soaked in a thousand practical details of building: he picked out the best workman in each gang, watched him, talked with him, learned all he could of that man's particular trick; and it all went down in the little green book. For at the back of his head was always the thought of the time when he should use all this knowledge in his own business. Then one day when he had learned all he could learn from being timekeeper, he walked into Weil's office again and proposed that they make him one of the firm's superintendents of construction. "Old Weil fairly stuttered with the surprise of this audacious proposition. He demanded to know what qualifications the young man could show for so important a position, and Robert told him about the year he had had with the country builder and the three summer vacations with the country surveyor--which made no impression whatever on Mr. Weil until Robert produced the little green book. Mr. Weil glanced at some of the figures in the book, snorted, looked hard at his ambitious timekeeper, who looked back at him with his keen young eyes and waited. When he left the office he had been promised a tryout on a small job near the offices, where, as old Weil said, they could keep an eye on him. That night he wrote to the girl back home that she must get ready to marry him at a moment's notice." Mrs. Trask leaned back in her chair and smiled with a touch of sadness. "The wonder of youth! I can see him writing that letter, exuberant, ambitious, his brain full of dreams and plans--and a very inadequate supper in his stomach. The place where he lived--he pointed it out to me once--was awful. No girl of Rob's class--back home his folks were 'nice'--would have stood that lodging-house for a night, would have eaten the food he did, or gone without the pleasures of life as he had gone without them for two years. But there, right at the beginning, is the difference between what a boy is willing to go through to get what he wants and what a girl would or could put up with. And along with a better position came a man's responsibility, which he shouldered alone. "'I was horribly afraid I'd fall down on the job,' he told me long afterward. 'And there wasn't a living soul I could turn to for help. The thing was up to me alone!'"
