"I'll do all thim things and wan more—and thot wan is the shtiffest av thim all: the saints aidin' me, Misther Leckhard, I'll shtay awake."

There was a short siding at the summit of the pass, and by good hap, Gallagher met Folsom with the first string of empties at that point: or rather, giving the bit of good luck full credit, he heard the roaring of Folsom's exhaust as the first of the opposing trains pounded up the dangerous western grade, and hastily backed up and took the summit siding.

Pitching over the hill with the "01" the moment Folsom's tail-lights had passed the outlet switch, Gallagher had a sharp attack of memory. The day before, in the Horse Creek yard, he had seen and remarked a jagged scratch on the side of the Nadia. Hence, he was watching for the narrow rock cuttings, and the three passages perilous on the cliff face were made in safety.

Once off the mountain, however, the greater peril began to assert itself. For a time the Irishman kept himself fully awake and alert by pushing the 956 to the ragged edge of hazard, scurrying over the short tangents and lifting her around the curves in breath-taking spurts. Later this expedient began to lose its fillip. Since the train was running wholly on the air-brakes there was nothing for the fireman to do, and Jackson, the loyalest understudy Gallagher had ever known, tumbled from his box in a doze, staggered across the gang-way into the half-filled tender, and fell like a man anæsthetized full length on the coal. Gallagher did not try to arouse him.

"'Tis hell for wan, an' twice hell for two," he muttered; and then he shifted his right hand to the brake-cock and grasped the hot throttle lever with the ungloved left. And for a time the pain of the burn sufficed.

It was another piece of luck, good or bad, that made Ten Mile station the special train's meeting point with the second train of empties. This time it was Graham, the other engineer, who heard. He had stopped at Ten Mile on the bare chance that the wire between that point and Saint's Rest had been repaired; public opinion to the contrary notwithstanding, an engineer does not run "wild" when he can help it.

The engineer of the third section had come out of the night operator's office disappointed, and was climbing to his engine to pull out, when he heard, or thought he heard, the dull rumble of a train racing down the canyon. It came in sight while he listened, and the yellow flare told him that it was either Gallagher or Folsom doubling back on one of the construction engines. What startled him was the fact that the coming train appeared to be running itself; there was no warning whistle shriek and no slackening of speed.

Graham was a Scotchman, slow of speech, slow to anger, methodical to the thirty-third degree. But in an emergency his brain leveled itself like a ship's compass gimballed to hang plumb in the suddenest typhoon. Three shrill whistle calls sent a sleepy flagman racing to set the switch of the siding. With a clang the reversing lever came over and the steam roared into the cylinders.

The Scotchman had the grade to help him, which was fortunate. When he had the string of empties fairly in retreat, the beam of Gallagher's headlight was shining full in his face and blinding him. For a heart-breaking second he feared that the opposing train would follow him in on the siding; there was but an instant for the flicking of the switch. But by this time the sleepy flagman was wide awake, and he jerked the switch lever for his life the moment Graham's engine had cleared the points. It was the closest possible shave. Gallagher's cab ticked the forward end of the other engine's running board in passing, and if Graham had not been still shoving backward with the throttle wide open, the "01," being wider than its piloting engine, would have had its side ripped out.

Graham had a glimpse into the cab of the 956 as it passed and saw Gallagher, sitting erect on his box with wide-staring eyes. He knew the symptoms, and feared that he had only postponed the catastrophe. The siding was a short one, and he knew that in backing down he must inevitably have shoved the rear end of his train out upon the main line at the lower switch. Once again the level brain righted itself to the emergency. Four sharp shrieks of the whistle for switches, a jamming of the whistle lever to set the canyon echoes yelling in the hope of arousing Gallagher, and Graham slammed his engine into the forward motion without pausing to close the throttle. There was a grinding of fire from the wheels, a running jangle of slack-taking down the long line of empties, and the freight train shot ahead, snatching its rear end out of harm's way just as Gallagher, dreaming that his boiler had burst and that all the fiends of the pit were screeching the news of it, came to life and snapped on the air.
