"But I don't know anything about it," said Toddles, still helplessly.
"That's just it," returned Donkin smoothly. "You never tried to learn."
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.
Toddles, mindful of Donkin's words, didn't fight so much as the days went by, though he found it difficult to swear off all at once; and on his runs he studied his Morse code, and he had the "calls" of every station on the division off by heart right from the start. Toddles mastered the "sending" by leaps and bounds; but the "taking" came slower, as it does for everybody—but even at that, at the end of six weeks, if it wasn't thrown at him too fast and hard, Toddles could get it after a fashion.
Take it all around, Toddles felt like whistling most of the time; and, pleased with his own progress, looked forward to starting in presently as a full-fledged operator. He mentioned the matter to Bob Donkin—once. Donkin picked his words and spoke fervently. Toddles never brought the subject up again.
And so things went on. Late summer turned to early fall, and early fall to still sharper weather, until there came the night that the operator at Blind River muddled his orders and gave No. 73, the westbound fast freight, her clearance against the second section of the eastbound Limited that doomed them to meet somewhere head-on in the Glacier Cañon; the night that Toddles—but there's just a word or two that comes before.
When it was all over, it was up to Sam Beale, the Blind River operator, straight enough. Beale blundered. That's all there was to it; that covers it all—he blundered. It would have finished Beale's railroad career forever and a day—only Beale played the man, and the instant he realized what he had done, even while the tail lights of the freight were disappearing down the track and he couldn't stop her, he was stammering the tale of his mistake over the wire, the sweat beads dripping from his wrist, his face gray with horror, to Bob Donkin under the green-shaded lamp in the despatchers' room at Big Cloud, miles away.
Donkin got the miserable story over the chattering wire—got it before it was half told—cut Beale out and began to pound the Gap call. And as though it were before him in reality, that stretch of track, fifteen miles of it, from Blind River to the Gap, unfolded itself like a grisly panorama before his mind. There wasn't a half mile of tangent at a single stretch in the whole of it. It swung like the writhings of a snake, through cuts and tunnels, hugging the cañon walls, twisting this way and that. Anywhere else there might be a chance, one in a thousand even, that they would see each other's headlights in time—here it was disaster quick and absolute.
Donkin's lips were set in a thin, straight line. The Gap answered him; and the answer was like the knell of doom. He had not expected anything else; he had only hoped against hope. The second section of the Limited had pulled out of the Gap, eastbound, two minutes before. The two trains were in the open against each other's orders.
In the next room, Carleton and Regan, over their pipes, were at their nightly game of pedro. Donkin called them—and his voice sounded strange to himself. Chairs scraped and crashed to the floor, and an instant later the super and the master mechanic were in the room.
"What's wrong, Bob?" Carleton flung the words from him in a single breath.
Donkin told them. But his fingers were on the key again as he talked. There was still one chance, worse than the thousand-to-one shot; but it was the only one. Between the Gap and Blind River, eight miles from the Gap, seven miles from Blind River, was Cassil's Siding. But there was no night man at Cassil's, and the little town lay a mile from the station. It was ten o'clock—Donkin's watch lay face up on the table before him—the day man at Cassil's went off at seven—the chance was that the day man might have come back to the station for something or other!
Not much of a chance? No—not much! It was a possibility, that was all; and Donkin's fingers worked—the seventeen, the life and death—calling, calling on the night trick to the day man at Cassil's Siding.
Carleton came and stood at Donkin's elbow, and Regan stood at the other; and there was silence now, save only for the key that, under Donkin's fingers, seemed to echo its stammering appeal about the room like the sobbing of a human soul.
"CS—CS—CS," Donkin called; and then, "the seventeen," and then, "hold second Number Two." And then the same thing over and over again.
And there was no answer.
It had turned cold that night and there was a fire in the little heater. Donkin had opened the draft a little while before, and the sheet-iron sides now began to pur red-hot. Nobody noticed it. Regan's kindly, good-humored face had the stamp of horror in it, and he pulled at his scraggly brown mustache, his eyes seemingly fascinated by Donkin's fingers. Everybody's eyes, the three of them, were on Donkin's fingers and the key. Carleton was like a man of stone, motionless, his face set harder than face was ever carved in marble.
It grew hot in the room; but Donkin's fingers were like ice on the key, and, strong man though he was, he faltered.
"Oh, my God!" he whispered—and never a prayer rose more fervently from lips than those three broken words.
Again he called, and again, and again. The minutes slipped away. Still he called—with the life and death—the "seventeen"—called and called. And there was no answer save that echo in the room that brought the perspiration streaming now from Regan's face, a harder light into Carleton's eyes, and a chill like death into Donkin's heart.
Suddenly Donkin pushed back his chair; and his fingers, from the key, touched the crystal of his watch.
"The second section will have passed Cassil's now," he said in
