Casey grinned at his old comrade. “Mac, yez do me a favor. Uncouple the car.”

McDermott stepped between the cars and the rattle and clank of iron told that he had complied with Casey’s request. Collins, with all the men on the ground, grasped Casey’s idea.

“By God! Casey can you do it? There’s down-grade for twenty miles. Once start this gravel-car and she’ll go clear to the hills. But—but—”

“Collins, it’ll be aisy. I’ll slip through thot pass loike oil. Thim Sooz won’t be watchin’ this way. There’s a curve. They won’t hear till too late. An’ shure they don’t niver obsthruct a track till the last minute.”

“But, Casey, once through the pass you can’t control that gravel-car. The brakes won’t hold. You’ll run square into the general’s train—wreck it!”

“Naw! I’ve got a couple of ties, an’ if thot wreck threatens I’ll heave a tie off on the track an’ derail me private car.”

“Casey, it’s sure death!” exclaimed Collins. His voice and the pallor of his face and the beads of sweat all proclaimed him new to the U. P. R.

“Me boy, nothin’s shure whin yez are drillin’ with the Paddies.”

Casey was above surprise and beyond disdain. He was a huge, toil-hardened, sun-reddened, hard-drinking soldier of the railroad, a loquacious Irishman whose fixed grin denied him any gravity, a foreman of his gang. His chief delight was to outdo his bosom comrade, McDermott. He did not realize that he represented an unconquerable and unquenchable spirit. Neither did his comrade know. But under Casey’s grin shone something simple, radiant, hard as steel.

“Put yer shoulders ag’in’ an’ shove me off,” he ordered.
