"Better keep it till I do," said the stalwart one, offering it back.

"No; I'm not afraid to pay you in advance. You are going to do your best, and I am not trying to bribe you. It's yours, whether we make it or not."

The big man thrust the bills into his pocket and opened the throttle. "You go over there and sit down and hold your hair on," he commanded. "I'm goin' to break the record when we get out into daylight on the other side o' the mountain."

Jeffard was still groping for hand and foot holds on the fireman's seat when the locomotive rolled out of the western portal of the summit tunnel and the record-breaking began. Of the brain-benumbing rush down the gorges of the Frying Pan on a flying locomotive, one recalls but a confused memory; a phantasmagoric jumble of cliffs and chasms, backward-flitting forests and gyrating mountain peaks, trestles and culverts roaring beneath the drumming wheels, the shrieks of the whistle and the intermittent stridor of escaping steam in the iron throat of the safety-valve; a goblin dance of matter in motion to a war blast of chaotic uproar. One sets the teeth to endure, and comes back to the cosmic point of view with a deep-drawn sigh of relief when the goblin dance is over, and the engine halts at the junction where the Aspen branch leaves the main line and crosses the Frying Pan to begin the ascent of the Roaring Fork.

From this point the competing railways parallel each other, and at the junction the trains on either line are within whistle call. To the engineer's question the telegraph operator nodded an affirmative.

"Yep; she's just gone by. That's her whistlin' for Emma now. What's the rush?—backed to beat her into Aspen?"

The engineer nodded in his turn, and signed the order for the right of way on the branch. A minute later the junction station was also a memory, and Jeffard was straining his eyes for a glimpse of the passenger train on the other line. A short distance to the southward the rival lines meet and cross, exchanging river banks for the remainder of the run to Aspen. The passenger train was first at the crossing, and Jeffard had his glimpse as the engine slackened speed. Not to lose a rail-length in the hard-fought race, Jeffard's man ran close to the crossing to await his turn, and the light engine came to a stand within pistol shot of the train, which was slowly clanking over the crossing-frogs. Jeffard slipped from his seat and went over to the engineer's gangway. It would be worth something if he could make sure that Garvin was on the train.

The espial was rewarded and punished in swift sequence. The trucks of the smoking-car were jolting over the crossing, and Jeffard saw the head and shoulders of the insane one filling an open window. It was conspicuously evident that Garvin had drained the bottle to the frenzy mark. He was yelling like a lost soul, and shaking impotent fists at the halted engine. Jeffard's eye measured the distance to the moving car. It was but down one embankment and up the other.

"That's my man," he said quickly to the engineer. "Do you suppose I could make it across?"

"Dead easy," was the reply; and Jeffard swung down to the step of the engine to drop off. The impulse saved his life. As he quitted his hold a hairy arm bared to the elbow was thrust out of the window next to the yelling maniac. There was a glint of sun-rays on polished metal, and a pistol ball bit out the corner of the cab under the engineer's arm-rest. Jeffard desisted, and climbed to his place when the moving train gathered headway.
