"Oh, do you?" retorted the old railroader, disguising his good nature under his usual mask of grimness. "Well, you're ahead of time fifteen minutes, so just sit down and behave yourself till I get those freights over yonder untangled. Anxious for work, are you?" he pursued quizzically. "You'll have enough of it. I'm ordered up to the crossings tower, and you'll have to take the first half-night shift here alone. Think you can manage it?"

"I can try, Mr. Knight," was the modest but resolute reply.

[CHAPTER II--UP THE LADDER]

Ralph Fairbanks was a full-fledged railroader, young as he was.

Those who have read the preceding volume of this series, will have no difficulty in recognizing the able and intrepid hero of "Ralph of the Roundhouse" in the manly young fellow who had just reported for duty to grim old Jack Knight.

Ralph had lived at Stanley Junction since childhood. His father had been a railroad man before him. In fact, John Fairbanks had been instrumental in bringing the Great Northern to Stanley Junction. He had in part supervised its construction.

He had died before reaping the reward of his services. However, Mrs. Fairbanks and his friends knew that he owned some twenty thousand dollars' worth of railroad stock besides his home. This stock could not be located after his death, and Ralph and his mother found themselves totally unprovided for.

They knew that in his stock deals Mr. Fairbanks had a partner. This was Gasper Farrington, a miserly but wealthy magnate of the town.

To their astonishment, this man now came forward with a mortgage on the homestead that Mrs. Fairbanks was positive had been paid off before her husband's death.

Of this, however, she could furnish no written proof. Farrington professed great sympathy for the family of his dead partner, but nevertheless he insisted on collecting the interest on the mortgage.
