It took all of this day to climb out of the canyon. The second was a slow march of thirty miles into a scrub cedar and pinyon forest, through which the great red and yellow walls of the canyon could be seen. That night Slone found a water-hole in a rocky pocket and a little grass for Nagger. The third day's travel consisted of forty miles or more through level pine forest, dry and odorous, but lacking the freshness and beauty of the forest on the north side of the canyon. On this south side a strange feature was that all the water, when there was any, ran away from the rim. Slone camped this night at a muddy pond in the woods, where Wildfire's tracks showed plainly. On the following day Slone rode out of the forest into a country of scanty cedars, bleached and stunted, and out of this to the edge of a plateau, from which the shimmering desert flung its vast and desolate distances, forbidding and menacing. This was not the desert upland country of Utah, but a naked and bony world of colored rock and sand--a painted desert of heat and wind and flying sand and waterless wastes and barren ranges. But it did not daunt Slone. For far down on the bare, billowing ridges moved a red speck, at a snail's pace, a slowly moving dot of color which was Wildfire. On open ground like this, Nagger, carrying two hundred and fifty pounds, showed his wonderful quality. He did not mind the heat nor the sand nor the glare nor the distance nor his burden. He did not tire. He was an engine of tremendous power. Slone gained upon Wildfire, and toward evening of that day he reached to within half a mile of the stallion. And he chose to keep that far behind. That night he camped where there was dry grass, but no water. Next day he followed Wildfire down and down, over the endless swell of rolling red ridges, bare of all but bleached white grass and meager greasewood, always descending in the face of that painted desert of bold and ragged steps. Slone made fifty miles that day, and gained the valley bed, where a slender stream ran thin and spread over a wide sandy bottom. It was salty water, but it was welcome to both man and beast.
