Lifting his slide-board from the platform, Bart set it on the cog-rail midway of the track.

This rail was bolted to a wooden centerpiece on the ties, and consisted of two parallel strips of wrought angle-iron, connected by steel pins three inches apart, on which the cogs of the engine worked. He turned the nut on the brake-rod until the iron plates by means of which the speed of the board was retarded were in position under the flanges of the rail. Then he pulled on his gloves, jammed his cap down hard, and buttoned his reefer up to his neck.

Corey glanced at the black western sky. “You’re liable to hit the storm going down,” said he.

“Guess I can beat it out,” returned Bart. Seating himself on the slide-board, with the bundle of papers between his knees, he gripped the brake-handles. Almost of itself the board began moving.

“I’ll be at the Base House in ten minutes!” he called back, as he sped away down the slope toward the north, while behind him the drone of the wind almost drowned Corey’s shout.

“Good luck!”

The slide-board was the conveyance used by employés and trackmen in descending the mountain railroad. Although perilous for a novice, it was easy of management for an experienced hand. It was of seven-eighths-inch spruce, ten inches wide, and something over a yard long. Three cleats screwed across its top kept it from splitting. Underneath were two sets of “shoes,” the forward of wood, the rear of iron, parallel strips half an inch thick and four inches apart, just far enough for the top of the cog-rail to slide between them.

As Bart slipped downward, the black buildings on the summit were blotted out by driving clouds. Little by little he swerved westward, turning his back to the dawn, hearing only the hoarse murmur of the rising gale and the rattle of his board.

Guide-books say that the three and one-third miles from summit to base may be covered by slide-board in twenty minutes. Actually, the record is two minutes and forty-seven seconds. This can be appreciated when one remembers that there is a drop of four thousand feet, and that the average grade approximates one in four. Bart had made the trip some hundreds of times in his fourteen years on the road. Every morning that summer he had gone down before daybreak, in order that the little paper printed on the peak might have early distribution among the various hotels.

Faster and faster sped the board. The top of the rack was abundantly lubricated with oil from the cogs of the engine, and the grade was growing steeper. On the left a dim shaft flitted by, memorial of a life lost by exposure on the mountain years before.
