Whether merely from the change of an eighth of an inch or so in its hold upon the rim, or because his palm fitted better around the slight alteration of curve, Tom was conscious of the slightest measure of relief.

As quickly as he dared (for he knew that any sudden move would be fatal), he reached behind him with his left arm and, groping for the stub of limb, tore away from it the twigs which he knew would form an obstacle to placing the wheel rim with its network of spokes over this short projection.

The dead soreness of his straining shoulder blade ran down his arm, which throbbed painfully. His twitching, struggling fingers, straining against the weight which was forcing them open, clutched the rim. They were burning and yet seemed numb. Oh, if he could only wipe his palm and that rim with a dry handkerchief! He tightened his slipping fingers again and again. The muscles of his arm smarted as from a blow. He tightened his lips—and that seemed to help.

Carefully, though his aching breast pounded against the limb, he brought back his left hand, cautiously rubbed it against his khaki shirt, then encircled it about the rim. For a moment the weight seemed manageably light in the quick relief he felt.

Availing himself of the slight measure of refreshment he raised the machine a trifle, a trifle more, squirmed about to get in better position, bent, strained, got the bulky thing past his clutching legs, exerted every muscle of chest and abdomen, which now could assume some share of the strain, and by a superhuman effort of litheness and dexterity and all the overwhelming power of physical strength and frenzied resolution, he succeeded in slipping the wheel rim over the stubby projection behind him.

If he had been running for ten miles he could not have been more exhausted. His breast heaved with every spasmodic breath he drew. His shoulder blades throbbed like an aching tooth. His dripping palm was utterly numb. For a few brief, precious seconds he sat upon the limb with a sense of unutterable relief, and mopped his beaded forehead. And the sun's full, round face smiled approvingly upon him.

Meanwhile the minutes flew.

Hurrying now, he scrambled down the tree trunk where he had a better and less discouraging view of the situation. He saw that Uncle Sam hung about five feet from the brink and just clear of the water. If the bank on this side was less precipitous than on the other there would be some prospect of rescuing his machine without serious damage. He could afford to let it get wet provided the carburetor and magneto were not submerged and the gas tank——

The gas tank. That thought stabbed him. Could the gasoline have flowed out of the tank while the machine was hanging up and down? That would bring the supply hole, with its perforated screw-cover, underneath.

He waded cautiously into the water and found to his infinite relief that the submerged bank formed a gentle slope. He could not go far enough to lift his machine, but he could reach to wiggle it off its hook and then guide it, in some measure, enough to ease its fall and keep its damageable parts clear of the water. At least he believed he could. In any event, he had no alternative choice and time was flying. After what he had already done he felt he could do anything. Success, however wearying and exhausting, gives one a certain working capital of strength, and having succeeded so far he would not now fail. His success in crossing had given him that working capital of resolution and incentive whence came his superhuman strength and overmastering resolve in that lonely tree. And he would not fail now.

Yet he could not bring himself to look at his watch. He was willing to venture a guess, from the sun, as to what time it was, but he could not clinch the knowledge by a look at the cruel, uncompromising little glass-faced autocrat in his pocket. He preferred to work in the less disheartening element of uncertainty. He did not want to know the hard, cold truth—not till he was moving.

Here now was the need of nice calculating, and Tom eyed the shore and the tree and the machine with the appraising glance of a wrestler eyeing his opponent. He broke several branches from the tree, laying them so as to form a kind of springy, leafy mound close to the brink. Then standing knee-deep he wiggled the wheel's rim very cautiously out to the end of its hanger, so that it just balanced there.

One more grand drive, one more effort of unyielding strength and accurate dexterity and—he would be upon the road.

The thought acted as a stimulant. Lodging one hand under the seat of the machine and the other upon a stout bar of the mechanism which he thought would afford him just the play and swing he needed, he joggled the wheel off its hanger, and with a wide sweep, in which he skillfully minimized the heavy weight, he swung the machine onto the springy bed which he had made to receive it.

Then, as the comrade of a wounded soldier may bend over him, he knelt down beside his companion upon the makeshift, leafy couch.

"Are you all right?" he asked in the agitation of his triumphant effort.

Uncle Sam did not answer.

He stood the machine upright and lowered the rest so that it could stand unaided; and he tore away the remnant of mud-guard which Uncle Sam had sacrificed in his role of combination engine and paddle-wheel.

"You've got the wires all tangled up in your spokes," Tom said; "you look like a—a wreck. What do you want with those old sticks of shingles? How are you off for gas—you—you old tramp?"

Uncle Sam did not answer.

"Anyway, you're all right," Tom panted; "only my arm is worse than your old mud-guard. We're a pair of—— Can't you speak?" he added breathing the deadly fatigue he felt and putting his foot upon the pedal. "What—do—you—say? Huh?"

And then Uncle Sam answered.

"Tk-tk-tk-tk-tk-r-r-r-r-r-r-r-r—— Never mind your arm. Come ahead—hurry," he seemed to say.
