Ralph could not believe that Glen was a schemer or anything of that sort. For all that, there was a decided mystery about him. He seemed to be afraid of Slump, appeared to shun the town and its people. Why was he wandering all about the country with a helpless old man? Why had he flushed up and acted embarrassed when Ralph had asked him several pointed questions? "Glen must certainly be questioned about the two men who had his grandfather in tow," decided Ralph, "for those fellows must be located and watched. I wish Bob Adair was here. He would soon let light in on the whole affair. I'd rather he would do it, for I feel very friendly towards Glen and I don't like hurting his feelings by seeming to pry into his private business." Ralph rested a few minutes on the porch when he reached home and then started down town. He was in a certain state of suspense, for the orders of the general superintendent were vague and unsatisfactory. Something was working, Ralph felt, in which he was to take an active part. The paymaster had indicated that affairs were being stirred up. Idleness and suspense worried the young railroader, however, and he anxiously awaited the coming interview with his superior officer. Ralph went down to the roundhouse and met many of his friends. Old Forgan, the fireman, described the disgust and dejection of Fogg at having a new running mate. Everybody had heard that Ralph had a layoff on account of a fall disabling him, and his arm in the sling won him a good deal of friendly sympathy. He made a tour of the general offices to learn that Mr. Little was laid up at home with a lame foot, and that the general superintendent was out of town. Ralph had the free run of the general offices, as the saying went. He was ambitious, energetic and popular, and the busiest man in the service had a pleasant nod and a kindly word for him as he went around the different departments. When he arrived at the train dispatcher's office, the young railroader went in and sat down. Ralph was in one of the most inviting places a man can get into, especially if he is interested in the workings of a big railway system. The thought came to him, as he sat watching the men who held in their keeping the lives of thousands of passengers, that not all the credit for a good swift run was due to the engineer and train crew. He smiled as he recalled how the newspapers told every day of the President or some big functionary out on a trip, and how at the end of the run he stopped beside the panting engine, and reaching up to shake the hand of the faithful, grimy engineer, would say: "Thank you so much for giving us a good run. I don't know when I have ridden so fast before," or words to that effect.
