"None the less, I am going to win out if it costs me the best year of my life. I'm going to swing to this thing till I make something out of it, if I have to put in some more winters like the one I have just come through—which was Sheol, with ice and snow in the place of the traditional fire and brimstone. If I have one good quality—as I sometimes doubt—it's the inability to know when I am satisfactorily and permanently licked."

Stuart Ford was shivering through the second of the winters on the gray, needle-winded day when he stood on the crusted drift, heartening his men who were breaking the way for further rammings of the scrap-heap 206 and her box-plow. During the summer which lay behind the pitiless storms and the blockading snows he had explored and planned, studied and schemed; and now a month of good weather would put the finishing touches preparatory upon the "notion" hinted at in the letter to Frisbie.

"That'll do, boys; we'll let Gallagher hit it a few times now," he sang out, when he saw that the weaker ones among the shovelers were stumbling numbly and throwing wild. "Get back to the car and thaw yourselves out."

The safety-valve of the 206 was stuttering under a gratifying increase of steam pressure when the superintendent climbed to the canvas-shrouded cab.

"Ha! two hundred and fifty pounds! That looks a little more like it, Michael. Now get all the run you can and hit her straight from the shoulder," he ordered, mounting to his seat on the fireman's box, and bracing himself for what should come.

Gallagher released the driver-brakes and let the 206 and the plow drift down the grade until his tender drawhead touched the laborers' car. Then the reversing lever went forward with a clang, and the steam squealed shrilly in the dry-pipe. For a thunderous second or two the driving-wheels slipped and whirled futilely on the snowy rails. Gallagher pounced upon the sand lever, whereat the tires suddenly bit and held and a long-drawn, fire-tearing exhaust sobbed from the stack.

"You've got her!" shouted Ford. "Now hit it—hit it hard!"

Swiftly the huge mass of engine and plow gathered headway, the pounding exhausts quickening until they blended in a continuous roar. The little Irishman stayed himself with a foot against the boiler brace; the fireman ducked under the canvas curtain and clung to the coal bulkhead; and Ford held on as he could.

The shock came like the crashing blow of a collision. The box-plow buckled and groaned with fine cracklings as of hard-strained timbers, and an avalanche of snow thrown up from its inclined plane buried engine and cab and tender in a smothering drift. Ford slid his window and looked out.

"Good work, Michael; good work! You gained a full car-length that time. Try it again."
