"For heaven's sake, don't do it here and now!" gasped Dick. "Let's get out of this spider's-web while we may." The old hunter postponed his prayerful motion, most reluctantly, as it would seem, and led the way in a silent withdrawal from the dangerous neighborhood of the ambushment. When we had pushed on somewhat higher up the gorge and stood on the confines of the upland valley for which it served as the approach, there was a halt for a council of war. Since it was now evident that the powder convoy was encamped in some hidden gorge or valley to which the cavern of the underground stream was one of the approaches, 'twas plain that we must climb to some height whence we could command a wider view. We were all agreed that the cavern entrance could not have been used by the entire company: this though the conclusion left the vanishing trail an unsolved riddle. For if the women could have been dragged through the low-springing arch of the waterway, we knew the horses could not--to say nothing of the certain destruction of the powder cargo in such a passage. So we addressed ourselves to the ascent of the northern mountain; though Richard and I would first beg a little space in which to drain the water from our boots, and to wring some pounds' weight of it from our clothes. That done, we fell in line once more; and being so fortunate as to hit upon a ravine which led to the cliff-crowned summit, the climb was shorn of half its toil and difficulty. Nevertheless, by the sun's height it was well on in the forenoon before we came out, perspiring, like sappers in a steam bath, upon the mountain top. As Yeates had guessed, this northern mountain proved to be a lofty table-land. So far as could be seen, the summit was an undulating plain, less densely forested than the valley, but with a thick sprinkling of pines to make the still, hot air heavy with their resinous fragrance. As it chanced, our ravine of ascent headed well back from the cliff edge, so we must needs fetch a compass through the pine groves before we could win out to any commanding point of view. The old borderer took his bearings by the sun and laid the course quartering to bring us out as near as might be on the heights above the gorge. But when we had gone a little way, a thinning of the wood ahead warned us that we were approaching some nearer break in the table-land.
