Slowly Tom loosened his perspiring left hand, not daring to withdraw it. The act seemed to communicate an extra strain to every part of his body. Of all the fateful moments of his life, this seemed to be the most tense. Then, in an impulse of desperation, he drew his left hand away. "I won't--let--go," he muttered. The muscles on his taut right arm stood out like cords. His forearm throbbed with an indescribable, pulling pain. There was a feeling of dull soreness in his shoulder blade. His perspiring hand closed tighter around the wheel's rim and he could feel his pulse pounding. His fingers tingled as if they had been asleep. Then his hand slipped a little. CHAPTER TWENTY-FOUR "TO HIM THAT OVERCOMETH" 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.
