"This is no time for useless recrimination, or I would ask how you could leave one who has been a generous friend, helpless and suffering," the girl said reproachfully. "My father is evidently seriously ill, and you are the only person I can turn to, for the hotel manager tells me there is no doctor within miles of us. So in my distress I must stoop to ask you, for his sake, what I can do?"

"Will you believe not only that I sympathize, but that I would gladly have given all I possess to save you from this shock?" Thurston began, but Helen cut him short by an impatient wave of the hand, and stood close beside him with distress and displeasure in her eyes.

"All that is outside the question—what can we do?" she asked imploringly.

"Only one thing," answered Geoffrey. "Bring up the best doctor in Vancouver by special train. I'm going now to hold up the fast freight. Gather your courage. I will be back soon after daylight with skilled assistance."

He went out before the girl could answer, and, comforted, Helen hurried back to her father's side. Whatever his failings might be, Thurston was at least a man to depend upon when there was need of action.

There was a little platform near the hotel where trains might be flagged for the benefit of passengers, but the office was locked. Thurston, who knew that shortly a freight train would pass, broke in the window, borrowed a lantern, lighted it, and hurried up the track which here wound round a curve through the forest and over a trestle. It is not pleasant to cross a lofty trestle bridge on foot in broad daylight, for one must step from sleeper to sleeper over wide spaces with empty air beneath, and, as the ties are just wide enough to carry the single pair of rails, it would mean death to meet a train. Geoffrey nevertheless pressed on fast, the light of the blinking lantern dazzling his eyes and rendering it more difficult to judge the distances between the ties—until he halted for breath a moment in the center of the bridge. White mist and the roar of hurrying water rose out of the chasm beneath, but another sound broke through the noise of the swift stream. Geoffrey hear the vibratory rattle of freight cars racing down the valley, and he went on again at a reckless run, leaping across black gulfs of shadow.

The sound had gained in volume when he reached firm earth and ran swiftly towards the end of the curve, from which, down a long declivity, the engineer could see his lantern. Panting, he held the light aloft as a great fan-shaped blaze of radiance came flaming like a comet down the track.

Soon he could dimly discern the shape of two huge mountain engines, while the rails trembled beside him, and a wall of rock flung back the din of whirring wheels. The fast freight had started from the head of Atlantic navigation at Montreal, and would not stop until the huge cars rolled alongside the Empress liner at Vancouver, for part of their burden was being hurried West from England around half the world to China and the East again. The track led down-grade, and the engineers, who had nursed the great machines up the long climb to the summit, were now racing them down hill.

Waving the lantern Geoffrey stood with a foot on one of the rails and every sense intent, until the first engine's cow-catcher was almost upon him. Then he leaped for his life and stood half-blinded amid whirling ballast and a rushing wind, as, veiled in thick dust, the great box cars clanged by. He was savage with dismay, for it seemed that the engineer had not seen his signal; then his heart bounded, a shrill hoot from two whistles was followed by the screaming of brakes. When he came up with the standing train at the end of the trestle, one engineer, leaning down from the rail of the cab, said:

"I saw your light away back, but was too busy trying to stop without smashing something to answer. Say, has the trestle caved in, or what in the name of thunder is holding us up?"
