Along this trail and above the last vestige of its standing trees a man could be seen, walking eastward and upward, one bright afternoon in August, a couple of years ago. He moved slowly, for he was heavily built and obviously not much used to climbing, for he paused often to breathe. The air at that altitude is thin and, to the one not accustomed to it, most unsatisfying. In the intervals of his pauses the traveler's eyes swept the heights and explored each canyon wall as if in search of a resting-place. Around him the conies cried and small birds skimmed from ledge to ledge, but his dark face did not lighten with joy of the beauty which shone over his head nor to that which flamed under his feet. It was plain that he was too preoccupied with some inner problem, too intent on his quest, to give eye or ear to the significance of bird or flower. Huge Solidor, bare and bleak, rose grandly to the north, propping the high-piled shining clouds, and the somber, dust-covered fields of snow showed to what far height his proud summit soared above his fellows. Little streams of icy water trickled through close-knit, velvety sward whereon small flowers, white and gold and lilac, showed like fairy footprints. Down from the pass a chill wind, delicious and invigorating, rushed as palpably as if it were a liquid wave. In all this upper region no shelter offered to the tired man. A few minutes later, as he rounded the sloping green bastion which flanks the peak to the south, the man's keen eyes lighted upon a small cabin which squatted almost unnoticeably against a gray ledge some five hundred feet higher than the rock whereon he stood. The door of this hut was open and the figure of a man, dwarfed by distance, could be detected intently watching the pedestrian on the trail. Unlike most cabin-dwellers, he made no sign of greeting, uttered no shout of cheer; on the contrary, as the stranger approached he disappeared within his den like a marmot. There was something appealing in the slow mounting of the man on foot. He was both tired and breathless, and as he neared the cabin (which was built on ground quite twelve thousand feet above sea-level) his limbs dragged, and every step he made required his utmost will. Twice he stopped to recover his strength and to ease the beating of his heart, and as he waited thus the last time the lone cabin-dweller appeared in his door and silently gazed, confronting his visitor with a strangely inhospitable and prolonged scrutiny. It was as if he were a lonely animal, jealous of his ground and resentful even of the most casual human inspection. The stranger, advancing near, spoke. "Is this the trail to Silver Plume?" he asked, his heaving breast making his speech broken. "It is," replied the miner, whose thin face and hawk-like eyes betrayed the hermit and the man on guard. "How far is it across the pass?" "About thirty miles." "A good night's walk. Are there any camps above here?" "None."
