What Mr. Grant had to say about Ralph's advancement came true a little later, and those who care to follow our hero's future career may do so in the next story of this series, to be called, "Ralph, the Train Dispatcher; or, The Mystery of the Pay Car." In that volume we shall meet many of our old friends once more, and see what our hero did when new difficulties confronted him. One day Ralph was surprised to receive a visit from Marvin Clark and Fred Porter. He received them both warmly, and soon learned that Clark had fixed up his trouble over railroad work, and with his parent, and had secured a good position for Fred, so that the latter would no longer need to lead a roving life. "But I must have one more ride with you, Fairbanks," said Fred. "And I'll go along," said the son of the railroad president. "With pleasure!" cried Ralph. "Come on!" And he led the way to where No. 999 stood ready for the next run. The trip was a grand success. And here we will, for the present, at least, say good-by to Ralph of the Overland Express.
