Riverton was made on time and with no unpleasant incident to mar a schedule trip. No. 999 was run to a siding, and Ralph and Fogg had over two hours on their hands to spend as they chose. They had brought their lunch, and they dispatched the best part of it in the cab. Mrs. Fairbanks had put it up in a basket, and a two-quart fruit jar held the cold coffee. After the repast Fogg fixed the fire and they strolled down to the depot. The station agent was an old acquaintance of Ralph. He knew Van Sherwin, Limpy Joe and the people up at the Short Line railroad, kept posted on their progress pretty closely, and he had a good deal of interesting railroad gossip to retail to Ralph. "Oh, by the way," he observed incidentally, after they had conversed for some time, "there was a spruce young fellow here this morning asking very particularly about 999 and her movements. He mentioned your name too." "Who was he?" inquired Ralph. "I never saw him before. He was curious all about your run, hung around a while and then disappeared. I haven't seen him since." "Describe him, won't you?" and the station agent did so. Ralph was sure that the stranger was the youth he had known as Marvin Clark. From that time on until the train got ready for the return trip, the young railroader kept his eyes open for a glimpse of his acquaintance with the double identity. The latter, however, up to the time No. 999 steamed out from Riverton, did not put in an appearance. "Well, nobody tackled us at Riverton," observed Ralph, as he and Fogg settled down comfortably to their respective tasks. "Better not," retorted the fireman keenly. "I just made a little purchase this morning, and I'm going to stand no fooling," and he touched his hip pocket meaningly. "Have a swig?" he inquired additionally, as he reached for the jar of coffee and took a drink. "Oh, I could feast on my mother's coffee all day," observed Ralph as the jar was passed to him. "Now, then, you finish it up and hand me one of those doughnuts." The little refection seemed to add to the satisfaction of the moment. Their run was a slow one, and there was little to do besides keeping the machinery in motion. The day was warm, but the air was balmy. The landscape was interesting, and they seemed gliding along as in a pleasing dream. Later, when he analyzed his sensations, the young railroader, recalling just these impressions, knew that they were caused by artificial conditions. Ralph relapsed into a dream--indeed, he was amazed, he was startled to find himself opening his eyes with difficulty, and of discovering his fireman doubled up in his seat, fast asleep. He tried to shout to Fogg, realizing that something was wrong. He could not utter a word, his tongue seemed glued to the roof of his mouth. Ralph barely managed to slip to his feet in an effort to arouse his cab mate.
