A call had come giving a "sine" or signature that never ran over the wire without making every man in the dispatcher's office sit up and take notice--the "sine" of the president of the Great Northern himself. "For you, Mr. Fairbanks," spoke the old operator with a vast chuckle and excessive politeness: "Mr. Fairbanks, Chief Dispatcher Great Northern: Congratulations." "Fairbanks," spoke the road officer, grasping the hand of the young railroader warmly, "I'm proud of you!" Ralph flushed with pride and pleasure. But however warmly the generous words of commendation from the railroad men thrilled the young chief dispatcher, they paled into insignificance when the lad, on reaching home that night, heard his mother say: "Ralph, my son, you have made me very proud!" And then, woman-like, she added: "But don't do it again, Ralph. You--you might get hurt!" "All right, mother," he promised, as he kissed her. "Only I don't believe those chaps will have a chance to make trouble for me or the railroad again--that is, not right away." THE END This Isn't All!

THE RAILROAD SERIES By ALLEN CHAPMAN Author of the "Radio Boys," Etc. Uniform Style of Binding. Illustrated. Every Volume Complete in Itself. In this line of books there is revealed the whole workings of a great American railroad system. There are adventures in abundance--railroad wrecks, dashes through forest fires, the pursuit of a "wildcat" locomotive, the disappearance of a pay car with a large sum of money on board--but there is much more than this--the intense rivalry among railroads and railroad men, the working out of running schedules, the getting through "on time" in spite of all obstacles, and the manipulation of railroad securities by evil men who wish to rule or ruin.
