Touching Drummond's arm, he slid down a slab of rock and crouched in the gloom on the ledge below. His boots had scratched the stone, and he listened when Drummond came down, but there was no movement in the camp. Dropping from the ledge, he reached the shingle, which rattled sharply, and for a moment or two he stopped and held his breath. He heard nothing, and making Drummond a sign to be cautious, went on again. They were now confronted by perhaps the most dangerous part of their task, for one cannot cross a stony beach in silence and men used to the wilds are easily wakened by a suspicious noise. Besides, the water glimmered, and Thirlwell would have liked a darker background. Still he meant to reach the canoes, and moved on, leaning forward to shorten his height and stepping as gently as he could. When the stones rattled he and Drummond sank down and waited, but heard nothing to alarm them, and at length stopped and lay down beside the canoes. They could not be seen now, but what they must do next was risky, and Thirlwell wanted to get his breath. Although he had not used much muscular exertion, his nerves tingled and his face was wet with sweat. After a few moments, he got on his knees and felt inside the canoe. It had not been unloaded and this was the craft to launch, although the weight would make a difference. Lying down again, he felt along the keel and found that the gravel was small and mixed with sand. Then he touched something round and knew that a roller had been put under the canoe in order that she might be pulled up without disturbing the cargo. This was a stroke of luck, because it would help him to run her down. He touched Drummond, and getting up seized the gunwale. They strained their muscles, but for a moment or two could not move the craft; then the roller jarred across a stone, there was a crunch of gravel, and she stopped, a foot lower down. Thirlwell gasped and moved his hands to get another grip. He thought they had made an alarming noise, but it was too late to be cautious. They must finish the job. "Lift her as you shove!" he said. She went a yard, with the roller jolting in the sand, and there was a splash as her after-end took the water. He could not understand why the packers had not wakened, but there was no movement in the camp, and the next effort would be easier, since the stern was nearly afloat. "Again!" he gasped. "Quietly, but with all your strength!" The roller ran smoothly and they followed the canoe down. When their feet were in the water they gave her a last push and small ripples splashed about them as she slid out on the lake. The impetus would carry her some distance and the off-shore breeze would do the rest. "I guess we'll light out now," Drummond remarked.
