In front of them a deep trough opened up in the hills, but it was filled with giant forest, through which no track led, and only those who have traversed the dim recesses of the primeval bush can fully understand what this implies. The west winds swept through that gateway, reaping as they went, and here and there tremendous trees lay strewn athwart each other with their branches spread abroad in horrible tangles. Some had fallen amidst the wreckage left by previous gales, which the forest had partly made good, and there was scarcely a rod of the way that was not obstructed by half rotten trunks. Then there were thick bushes, and an undergrowth of willows where the soil was damp with thorny brakes and matted fern in between. In places, the growth was almost like a wall, and the men, who skirted the inlet, were glad to scramble forward among the rough boulders and ragged driftwood at the water's edge for some minutes at a time, until it was necessary to leave the beach behind. After the first few minutes, there was no sign of the gleaming water. They had entered a region of dim green shade, where the moist air was heavy with resinous smells. The trunks rose about them in tremendous columns; thorns clutched their garments, and twigs and brittle branches snapped beneath their feet. The day was cool, but the sweat of tense effort dripped from them, and when they stopped for breath at the end of an hour, Vane estimated that they had gone a mile. "I'll be content if we can keep this up," he said. "It isn't likely," Carroll, who glanced down at a big rent in his jacket, replied with a trace of dryness. A little farther on, they waded with difficulty through a large stream, and Carroll, who stopped, glanced round at a deep rift in a crag on one side of them. "I don't know if that could be considered a valley, but we may as well look at it," he suggested. They scrambled towards it, and reaching gravelly soil, where the trees were thinner, Vane surveyed the opening. It was very narrow, and appeared to lose itself among the rocks. The size of the creek which flowed out of it was no guide, because those ranges are scored by running water. "We won't waste time over that ravine," he said. "I noticed a wider one farther on, and we'll see what it's like, though Hartley led me to understand that he came down a straight and gently-sloping valley. The one we're in answers the description." It was two hours before they reached the second opening, and then Vane, unstrapping his packs, clambered up the steep face of a crag. When he came back his face was thoughtful and, sitting down, he lighted his pipe.
