Two steps took him up to the waist, and he had trouble in finding solid bottom at the next, because the gravel rolled and slipped away beneath his feet in the strong stream. The current also dragged hard at his limbs, and he set his lips tight when it crept up to his ribs. Then he lost his footing, and was washed away, plunging and floundering, with now and then one toe resting momentarily upon the bottom, until he was hurled against the first of the boulders with a crash that almost drove the little remaining breath out of his body. He clung to it desperately, gasping hard; and then with a determined struggle contrived to reach the second stone, against which the stream pressed him, without finding any support for his feet. A moment or two later, Vane was washed down towards him, and grabbing at the boulder held on by it. They said nothing to each other, but they looked at the sliding water between them and the opposite bank. Carroll was getting horribly cold, and felt the power ebbing out of him; he thought if he must swim across he had better do so at once. Launching himself forward, he felt the flood lap his breast, but as his arms went in he struck something violently with one leg and found that he could stand up on a submerged ledge. This carried him a yard or two, and though he stepped over the end of the ledge into deeper water, he reached a strip of shelving shingle, up which he staggered. Vane overtook him, and they scrambled up the slope ahead, which was a little less steep than the one they had descended. The work warmed them slightly, and they needed it, but as they strode on again, keeping to the foot of the hillside where the timber was less dense, a cold rain drove into their faces. It grew steadily thicker; the straps began to gall their wet shoulders, and their saturated clothing clung heavily about their limbs. In spite of this, they went on until nightfall, when it was difficult to make a fire, and after a reduced supper found a little humid warmth in their wet blankets. The next day's work was much the same, only that they crossed no rivers and it rained harder; and, when evening came, Carroll, who had burst one boot, was limping badly. They made camp among the dripping firs which partly sheltered them from the bitter wind, and shortly after supper both fell asleep. At evening next day they reached the head of the valley. It was still raining and heavy mists obscured the summits of the hills, but above the lower slopes of rocks glimmering snow ran up into the vapour. There were a few balsams and hemlocks about them, but no sign of a spruce. "Now," said Carroll, "I expect you'll be satisfied." Vane was no nearer to owning himself defeated than he had been when they first set out. "We know there's no spruce in this valley; and that's something," he replied. "When we come back again we'll try the next one." "It has cost us a good deal to make sure of the fact."
