May came, and stray last-year's mosquitoes, full-grown but harmless, crawled out of rock crevices and rotten logs. Crickets began to chirp, and more geese and ducks flew overhead. And still the river held. By May tenth, the ice of the Stewart, with a great rending and snapping, tore loose from the banks and rose three feet. But it did not go down-stream. The lower Yukon, up to where the Stewart flowed into it, must first break and move on. Until then the ice of the Stewart could only rise higher and higher on the increasing flood beneath. When the Yukon would break was problematical.
Two thousand miles away it flowed into Bering Sea, and it was the ice conditions of Bering Sea that would determine when the Yukon could rid itself of the millions of tons of ice that cluttered its breast.
On the twelfth of May, carrying their sleeping-robes, a pail, an ax, and the precious rifle, the two men started down the river on the ice.
Their plan was to gain to the cached poling-boat they had seen, so that at the first open water they could launch it and drift with the stream to Sixty Mile. In their weak condition, without food, the going was slow and difficult. Elijah developed a habit of falling down and being unable to rise. Daylight gave of his own strength to lift him to his feet, whereupon the older man would stagger automatically on until he stumbled and fell again.
On the day they should have reached the boat, Elijah collapsed utterly.
When Daylight raised him, he fell again. Daylight essayed to walk with him, supporting him, but such was Daylight's own weakness that they fell together.
Dragging Elijah to the bank, a rude camp was made, and Daylight started out in search of squirrels. It was at this time that he likewise developed the falling habit. In the evening he found his first squirrel, but darkness came on without his getting a certain shot. With primitive patience he waited till next day, and then, within the hour, the squirrel was his.
The major portion he fed to Elijah, reserving for himself the tougher parts and the bones. But such is the chemistry of life, that this small creature, this trifle of meat that moved, by being eaten, transmuted to the meat of the men the same power to move. No longer did the squirrel run up spruce trees, leap from branch to branch, or cling chattering to giddy perches. Instead, the same energy that had done these things flowed into the wasted muscles and reeling wills of the men, ****** them move--nay, moving them--till they tottered the several intervening miles to the cached boat, underneath which they fell together and lay motionless a long time.
Light as the task would have been for a strong man to lower the small boat to the ground, it took Daylight hours. And many hours more, day by day, he dragged himself around it, lying on his side to calk the gaping seams with moss. Yet, when this was done, the river still held. Its ice had risen many feet, but would not start down-stream. And one more task waited, the launching of the boat when the river ran water to receive it.
Vainly Daylight staggered and stumbled and fell and crept through the snow that was wet with thaw, or across it when the night's frost still crusted it beyond the weight of a man, searching for one more squirrel, striving to achieve one more transmutation of furry leap and scolding chatter into the lifts and tugs of a man's body that would hoist the boat over the rim of shore-ice and slide it down into the stream.
Not till the twentieth of May did the river break. The down-stream movement began at five in the morning, and already were the days so long that Daylight sat up and watched the ice-run. Elijah was too far gone to be interested in the spectacle. Though vaguely conscious, he lay without movement while the ice tore by, great cakes of it caroming against the bank, uprooting trees, and gouging out earth by hundreds of tons.
All about them the land shook and reeled from the shock of these tremendous collisions. At the end of an hour the run stopped. Somewhere below it was blocked by a jam. Then the river began to rise, lifting the ice on its breast till it was higher than the bank. From behind ever more water bore down, and ever more millions of tons of ice added their weight to the congestion.
The pressures and stresses became terrific. Huge cakes of ice were squeezed out till they popped into the air like melon seeds squeezed from between the thumb and forefinger of a child, while all along the banks a wall of ice was forced up. When the jam broke, the noise of grinding and smashing redoubled. For another hour the run continued. The river fell rapidly.
But the wall of ice on top the bank, and extending down into the falling water, remained.
The tail of the ice-run passed, and for the first time in six months Daylight saw open water. He knew that the ice had not yet passed out from the upper reaches of the Stewart, that it lay in packs and jams in those upper reaches, and that it might break loose and come down in a second run any time; but the need was too desperate for him to linger. Elijah was so far gone that he might pass at any moment. As for himself, he was not sure that enough strength remained in his wasted muscles to launch the boat. It was all a gamble. If he waited for the second ice-run, Elijah would surely die, and most probably himself. If he succeeded in launching the boat, if he kept ahead of the second ice-run, if he did not get caught by some of the runs from the upper Yukon; if luck favored in all these essential particulars, as well as in a score of minor ones, they would reach Sixty Mile and be saved, if--and again the if--he had strength enough to land the boat at Sixty Mile and not go by.
