"On the pay roll he is John Klink. His other name is Spooner. He is stouter and has grown a beard since you saw him last." The superintendent uttered an exclamation of amazement. Steve briefly related all that had occurred. Under pressure, Spooner made a confession before they left the dry house that night of the whole miserable business. It was he who had dropped the dynamite into the shaft. But he declared that it was his partner, Marvin, also working in the mine under an assumed name, who had lured Steve Rush to the lower level and pushed him in. It was Marvin, too, who, by thrusting a monkey wrench into the machinery, had stripped the gear and put the cage mechanism out of business. That night the villainous and revengeful Spooner slept in a cell, where he was destined to remain until his trial and eventual sentence to a long term in prison. Marvin somehow got wind of the capture of his associate in crime and fled. He was never heard from in those parts again. On the following Monday morning the private car of the visiting officials once more drew up at the railroad station. Later in the day the Iron Boys were again summoned to the office of the superintendent. They supposed it was for a discussion of the Spooner case with Mr. Penton. They were surprised to find the officials of the company there awaiting them. After greeting the lads, Mr. Carrhart made a little speech in which he paid a glowing tribute to the brave boys, and at its conclusion he placed a packet in the hands of each. At the meeting of the officials there, a few days previous, it had been decided by vote to make the lads a present. The packets contained these presents. The lads protested, but Mr. Carrhart was almost sternly insistent. Upon arriving home Steve and Bob each found in his packet shares of stock in the big steel company amounting to one thousand dollars. It was a small fortune for them, yet they had earned it. At least the officials of the steel company considered that they had. The Iron Boys had done their full duty. But they were as yet merely at the beginning of their career. There were stirring days ahead of them, as well as other promotions for work well and faithfully done. The story of their further exciting experiences and advancement in the great industrial world are told in the next volume of this series, entitled, "THE IRON BOYS AS FOREMEN; Or, Heading the Diamond Drill Shift."
