There was nothing more said between them. Like two automatons, they started off across the parched grass, the heat waves rising and falling as they stumbled forward. Neither realized until then how thoroughly that hard climb up the rocks, the strain of continued peril, and the long abstinence from food had sapped their strength, yet to remain where they were meant certain death; all hope found its centre amid those distant beckoning trees. Mechanically the girl gathered back her straying tresses, and tied them with a rag torn from her frayed skirt. Hampton noted silently how heavy and sunken her eyes were; he felt a dull pity, yet could not sufficiently arouse himself from the lethargy of exhaustion to speak. His body seemed a leaden weight, his brain a dull, inert mass; nothing was left him but an unreasoning purpose, the iron will to press on across that desolate plain, which already reeled and writhed before his aching eyes.
No one can explain later how such deeds are ever accomplished; how the tortured soul controls physical weakness, and compels strained sinews to perform the miracle of action when all ambition has died. Hampton surely must have both seen and known, for he kept his direction, yet never afterwards did he regain any clear memory of it. Twice she fell heavily, and the last time she lay motionless, her face pressed against the short grass blades. He stood looking down upon her, his head reeling beneath the hot rays of the sun, barely conscious of what had occurred, yet never becoming totally dead to his duty. Painfully he stooped, lifted the limp, slender figure against his shoulder, and went straggling forward, as uncertain in steps as a blind man, all about him stretching the dull, dead desolation of the plain. Again and again he sank down, pillowing his eyes from the pitiless sun glare; only to stagger upright once more, ever bending lower and lower beneath his unconscious burden.
CHAPTER IV
ON THE NAKED PLAIN
It was two hundred and eighteen miles, as the crow flies, between old Fort Bethune and the rock ford crossing the Bear Water, every foot of that dreary, treeless distance Indian-haunted, the favorite skulking-place and hunting-ground of the restless Sioux. Winter and summer this wide expanse had to be suspiciously patrolled by numerous military scouting parties, anxious to learn more regarding the uncertain whereabouts of wandering bands and the purposes of malecontents, or else drawn hither and thither by continually shifting rumors of hostile raids upon the camps of cattlemen. All this involved rough, difficult service, with small meed of honor attached, while never had soldiers before found trickier foemen to contend against, or fighters more worthy of their steel.
One such company, composed of a dozen mounted infantrymen, accompanied by three Cree trailers, rode slowly and wearily across the brown exposed uplands down into the longer, greener grass of the wide valley bottom, until they emerged upon a barely perceptible trail which wound away in snake-like twistings, toward those high, barren hills whose blue masses were darkly silhouetted against the western sky. Upon every side of them extended the treeless wilderness, the desolate loneliness of bare, brown prairie, undulating just enough to be baffling to the eyes, yet so dull, barren, grim, silent, and colorless as to drive men mad. The shimmering heat rose and fell in great pulsating waves, although no slightest breeze came to stir the stagnant air, while thick clouds of white dust, impregnated with poisonous alkali, rose from out the grass roots, stirred by the horses' feet, to powder the passers-by from head to foot. The animals moved steadily forward, reluctant and weary, their heads drooping dejectedly, their distended nostrils red and quivering, the oily perspiration streaking their dusted sides. The tired men, half blinded by the glare, lolled heavily in their deep cavalry saddles, with encrusted eyes staring moodily ahead.
Riding alone, and slightly in advance of the main body, his mount a rangy, broad-chested roan, streaked with alkali dust, the drooping head telling plainly of wearied muscles, was the officer in command. He was a pleasant-faced, stalwart young fellow, with the trim figure of a trained athlete, possessing a square chin smoothly shaven, his intelligent blue eyes half concealed beneath his hat brim, which had been drawn low to shade them from the glare, one hand pressing upon his saddle holster as he leaned over to rest. No insignia of rank served to distinguish him from those equally dusty fellows plodding gloomily behind, but a broad stripe of yellow running down the seams of his trousers, together with his high boots, bespoke the cavalry service, while the front of his battered campaign hat bore the decorations of two crossed sabres, with a gilded "7" prominent between. His attire was completed by a coarse blue shirt, unbuttoned at the throat, about which had been loosely knotted a darker colored silk handkerchief, and across the back of the saddle was fastened a uniform jacket, the single shoulder-strap revealed presenting the plain yellow of a second lieutenant.
Attaining to the summit of a slight knoll, whence a somewhat wider vista lay outspread, he partially turned his face toward the men straggling along in the rear, while his hand swept across the dreary scene.
"If that line of trees over yonder indicates the course of the Bear Water, Carson," he questioned quietly, "where are we expected to hit the trail leading down to the ford?"
