One by one, for as long as daylight lasted, the urgent miles were pushed to the rear, and after the sun had gone behind the western mountains they made elaborately cautious preparations for the night. A small box canyon, well grassed, opened into the main valley on their left, and in this they unsaddled the horses and relieved the jacks of their packs and picketed the animals. Then, taking the needed provisions from one of the packs, they crossed the river by jumping from boulder to boulder in its bed, and made their camp fire well out of sight in a hollow on the opposite bank; this so that there might be no camp signs on the trail side of the stream. But in the short pipe-smoking interval which they allowed themselves after supper, Bromley laughed and said: “I guess there is a good bit of the ostrich in human nature, after all, Philip. Here we’ve gone to all sorts of pains to keep from leaving the remains of a camp fire in sight, when we know perfectly well that we are leaving a plain trail behind us for anybody who is even half a woodsman to follow. That’s a joke!” “Of course it is,” Philip agreed; and for a time before they extinguished the fire and recrossed the river to roll up in their blankets in the box canyon where the animals were grazing, they discussed the pressing matter of trail effacement without reaching any practical solution of the problem. The next morning they were up and on their way in the earliest dawn twilight. As yet, there were no signs of the pursuit. The mountain silences were undisturbed save by the drumming thunder of the swift little river and the soft sighing of the dawn precursor breeze in the firs. Convinced that all the haste they were making was clearly so much effort thrown away unless they could devise some means of throwing their followers off the track, they resumed the camp-fire discussion, falling back in the end, not upon experience, which neither of them had, but upon the trapper-and-Indian tales read in their boyhood. In these, running water was always the hard-pressed white man’s salvation in his flight, and, like the fleeing trapper, they had their stream fairly at hand. But the mountain river, coursing along at torrent speed, and with its bed thickly strewn with slippery boulders, was scarcely practicable as a roadway; it was too hazardous even for the sure-footed broncos, and entirely impossible for the loaded jacks.
