In the small hours of that night he made a discovery that electrified him. He found that the most commonly used section in his specifications, a twelve-inch I-beam, was listed under the English custom as weighing fifty-four pounds per foot, whereas the standardized American section, which possessed the same carrying strength, weighed four pounds less. Here was an advantage of eight per cent. in cost and freight! This put another round of the ladder beneath him; he was progressing well, but as yet he had learned nothing about his competitors. The next morning he had some more dictation for Peebleby's stenographer, and niched another sovereign from his sad little bank-roll. When the girl gave him his copy he fell into conversation with her and painted a picture of Yankeeland well calculated to keep her awake nights. They gossiped idly, she of her social obligations, he of the cyanide-tank business--he could think of nothing else to talk about. Adroitly he led her out. They grew confidential. She admitted her admiration for Mr. Jenkins from Edinburgh. Yes, Mr. Jenkins's company was bidding on the Krugersdorpf job. He was much nicer than Mr. Kruse from the Brussels concern, and, anyhow, those Belgian firms had no chance at this contract, for Belgium was pro-Boer, and--well, she had heard a few things around the office. Mitchell was getting "feed-box" information. When he left he knew the names of his dangerous competitors as well as those whom, in all likelihood, he had no cause to fear. Another step! He was gaining ground. In order to make himself absolutely certain that his figures would be low, there still remained three things to learn, and they were matters upon which he could afford to take no slightest chance of mistake. He must know, first, the dates of those other bids; second, the market-price of English steel at such times; and, third, the cost of fabrication at the various mills. The first two he believed could be easily learned, but the third promised to afford appalling difficulties to a man unfamiliar with foreign methods and utterly lacking in trade acquaintances. He went at them systematically, however, only to run against a snag within the hour. Not only did he fail to find the answer to question number one, but he could find no market quotations whatever on structural steel shapes such as entered into the Krugersdorpf job. He searched through every possible trade journal, through reading rooms and libraries, for the price of I-beams, channels, Z-bars, and the like; but nowhere could he even find mention of them. His failure left him puzzled and panic-stricken; he could not understand it. If only he had more time, he reflected, time in which to learn the usages and the customs of this country. But time was what he had not. He was tired, very tired from his sleepless nights and hours of daylight strain--and meanwhile the days were rushing past.
