"I think I can do it," said Ralph. "Very well, we give you free rein. Dismiss the crew and find a new one, as you like. You have orders for clear tracks over everything else. Lay out your schedule, give Glidden charge of the wires at headquarters, and get us that contract." "I will catch the first west through and report at eleven o'clock to-night," promised Ralph confidently. "Good for you, Fairbanks," commended the superintendent, slapping Ralph encouragingly on the shoulder. The next was a busy hour for Ralph. He studied the schedules, posted Glidden, took a hurry run for home and caught the train just as it was pulling out of the depot. Ralph reached Portland at half-past three in the afternoon. The special was on time and due in thirty minutes. She was to take water and coal at the yards, and Ralph, making himself known to the operator there, loitered outside. He saw the relief engineer appear. He was a man he did not know, and something about his face and manner impressed the young railroader rather unfavorably. The man set his dinner pail near the steps of the switch tower and walked about with the air of a person looking for some one. Then at a low whistle he started for a pile of ties some distance away. A man lurking there had beckoned to him. Ralph watched closely but drew back out of view. His keenest wits were on the alert in a second. He had recognized the lurker as a former unreliable employe of the Great Northern, discharged at the time of the great strike. Ralph feared this fellow might recognize him and dared not approach him any nearer. The twain conversed for only a moment. Then the lurker handed the engineer a bag. It held apparently about a bushel of some kind of stuff. The engineer took it and returned to the tower, his companion disappearing. Just then the special came down the tracks. The locomotive was disconnected and the tired and grimed crew drove for the dog house. In a minute or two the relief engine came down the tracks in charge of the fireman of the run. Ralph looked over the man. He had all the appearances of an honest, plodding fellow. After he had hitched to the train he got down to oil some cylinders. The engineer piled aboard with his bag, chucked it under the seat, and alighted again and went back to meet the conductor from the caboose. Of that bag Ralph had been suspicious from the start. He now deftly took the engine step, hauled out the bag, thrust it under the fireman's seat, swung shut its swinging board, and sat down at the engineer's post. "Hello!" exclaimed the fireman, stepping up into the cab--"who are you?" "Your engineer this trip." "Eh? Where does Bartley come in?" "He don't come in," replied Ralph definitely. "Your name Bartley?" inquired Ralph, as the engineer and the conductor came up to the locomotive. "That's me," smartly responded the man with a wondering look at Ralph. "Well, you are relieved from duty on this special trip," advised Ralph. "Hey--who says so?"
