"So he sent you, which is the next best thing." "Yes, sir, thank you." "I didn't know but he was here till I just looked in. So it appears that you have kept the machinery running. By-the-way," and Mr. Gardner stepped up the ascent from the boiler-room and closed the door between, "does that one-eyed Joe stick to his post?" The superintendent pursed his lips half humorously as he asked the question, but Larry felt sure that there was a serious purpose behind his words. "Yes, sir. He was here before I was this morning." "And does he mind your orders just the same as he does when your father is here?" "He has so far, sir." "That is right. Only you know some men don't fancy having a boy put in as boss over them; and he is one of the new hands, and I didn't know but he was cranky. Some of them are." Mr. Gardner pursed his smooth-shaven lips again and was gone. The moment the door closed after him, Larry wished he had told him of the strange actions of the group of new hands whom he had seen outside the entrance that noon. "But he may know more about it than I do. His eyes see about all there is to see," the boy reasoned. And he gave the matter scarce another thought until the great whistle delivered its parting roar that night. Although the six o'clock whistle was the signal for stopping the machinery and for the workmen to go to their homes, the engineer had to stay half an hour longer to see that the engine and boilers were left in proper shape for the night; then, when the night watchman came at half-past six, Larry could go home. But to-night, after firing up for the last time and blowing the whistle, Joe Cuttle did not go directly home. Instead, he went out into the yard and sauntered out toward the further end of the extensive works where the foundry was located. Larry, still distrustful, noticed this, and he wished then that he had mentioned what he had seen that noon to the superintendent. He stood in the doorway and furtively watched Joe until the latter disappeared beyond an angle of the building. Then he went in and meditatively drew the water from the glass gauges, tested the safety valve, wiped off the engine and finally locked the door of the engine-room. His work was done for the day. It yet lacked ten minutes of the half-hour, which would bring the night watchman, and he waited with his feeling of uneasiness growing stronger every moment until the time was up; and the watchman had not come. "He is usually ahead of time, instead of behindhand," Larry thought. He went to the door, and nearly collided with some one who was on the point of entering at the same time. "How d' do, Larry?" was the off-hand salutation of the newcomer, who was a short, stout man whom the boy recognized as Gideon Stark, a former watchman in the works, who had of late been employed as a helper in the moulding department. "Where is Jake?" Larry asked. "Sick," was the sententious reply. "And you're going to take his place to-night?"
