Toddles' eyes widened, and into Toddles' heart leaped a sudden joy. A new world seemed to open out before him in which aspirations, ambitions, longings all were a reality. A key! That was real railroading, the top-notch of railroading, too. First an operator, and then a despatcher, and—and—and then his face fell, and the vision faded.

"How'd I get a chance to learn?" he said miserably. "Who'd teach me?"

The smile was back on Donkin's face as he pushed his chair from the table, stood up, and held out his hand—man-to-man fashion.

"I will," he said. "I liked your grit last night, Hoogan. And if you want to be a railroad man, I'll make you one—before I'm through. I've some old instruments you can have to practise with, and I've nothing to do in my spare time. What do you say?"

Toddles didn't say anything. For the first time since Toddles' advent to the Hill Division, there were tears in Toddles' eyes for some one else to see.

Donkin laughed.

"All right, old man, you're on. See that you don't throw me down. And keep your mouth shut; you'll need all your wind. It's work that counts, and nothing else. Now chase yourself! I'll dig up the things you'll need, and you can drop in here and get them when you come off your run to-night."

Spare time! Bob Donkin didn't have any spare time those days! But that was Donkin's way. Spence sick, and two men handling the despatching where three had handled it before, didn't leave Bob Donkin much spare time—not much. But a boost for the kid was worth a sacrifice. Donkin went at it as earnestly as Toddles did—and Toddles was in deadly earnest.

When Toddles left the despatcher's office that morning with Donkin's promise to teach him the key, Toddles had a hazy idea that Donkin had wings concealed somewhere under his coat and was an angel in disguise; and at the end of two weeks he was sure of it. But at the end of a month Bob Donkin was a god! Throw Bob Donkin down! Toddles would have sold his soul for the despatcher.

It wasn't easy, though; and Bob Donkin wasn't an easy-going taskmaster, not by long odds. Donkin had a tongue, and on occasions could use it. Short and quick in his explanations, he expected his pupil to get it short and quick; either that, or Donkin's opinion of him. But Toddles stuck. He'd have crawled on his knees for Donkin anywhere, and he worked like a major—not only for his own advancement, but for what he came to prize quite as much, if not more, Donkin's approval.
