As the air grew thicker there shone from the sky, instead of the vivid white sunshine of a few hours before, only a dim, diffused, lurid light. Even to Curtis, sitting quartering in the saddle with his back twisted toward the wind, Brown Betty’s ears were barely visible. For a while he allowed the mare to follow the road herself, until he found that her sense of duty must be supplemented by authority. For, under the discomfort of the belaboring wind and stinging sand, she began to yield to her instinct to turn tail and drift before the storm. Then he knew that he must keep a firm hand on the bridle, and his attention at the highest pitch, or they would soon be wandering helplessly over the plain. He walked long distances beside the mare, with his body shielding her head and with speech and caress keeping up her courage. Their progress was slow, for the force of the storm was so great that, though it beat against them from the side, they could struggle through it only at a walk.

Hour after hour went by, and the only sign of its passage was that a dim, yellowish centre of illumination, that had once been the sun, crept slowly across the sky. As the day grew older Conrad’s pain from his injury became more acute. Most of the time he felt it only as an insistent background to the keen outward discomfort of stinging sand and pounding wind. But when an occasional sharper twinge brought it more vividly to his consciousness he swore a little between his teeth, and thought of the letter he was going to write to Dellmey Baxter. The particles of sand filled his hair and encrusted his face and neck until they were of a uniform brick-red. Constant effort and encouragement were necessary to keep Brown Betty in the road, and finally he was compelled to walk at her head most of the time and with a guiding hand on her bridle counteract the unflagging urge of her instinct to drift before the blast.

Thus they battled their way through the hot, beating wind and suffocating sand, while that vague core of light moved athwart the dirty heavens, dropped slowly down the western sky, and was swallowed up in the denser banks of dusk above the horizon. It had been too dark before for the discernment of objects, but a yellowish glare had filtered through the sand-laden air, lending a lurid, semi-translucence to the atmosphere. Now even that was gone, leaving a desert enveloped in pitchy darkness, while the wind roared about the ears of the travellers and pounded their bodies as with cudgels and the sand pelted their skins.

Most of the time Curtis depended upon the feel of the road under his feet to maintain his direction, but now and then it was necessary for him to get down on his hands and knees in order to recover the track from which they had begun to stray. Once his fingers came in contact with a small feathered body. The bird tried to start up under his hand. He knew it must be disabled and placed it inside his shirt. Thus they plodded on through the night and the storm, the pain in his shoulder growing keener and the torture of the wind and sand ever more nerve-racking.

At last the mare raised her head and gave a long whinny. Conrad felt sure that she was announcing their near approach to the food and shelter within the adobe houses. “What is it, Betty? Do you know where we are?” he asked, and she rubbed her nose against his face, nickered, and pulled at the bridle with the evident desire to turn from the direction they were pursuing. Curtis knew they were in a little hollow, and thought it might be that into which the road dipped after leaving the houses.

“All right, Betty,” he said. “I’ll follow your lead a little way, but be cautious, old girl, and don’t tie up to any lying hunches.” He slackened his hold on the bridle, and the mare started off eagerly. They climbed a hill, and presently Conrad was aware of a black mass before him. Putting out his hand he felt an adobe wall. The mare crowded close against it, and stopped. She had left the road, which took the hill at a long sloping angle from the foot of the rise, and had climbed straight up the steep incline. He felt his way around the corner, unfastened the door, and entered. An emphatic “Whew!” gave vent to his feeling of relief. The mare, close at his heels, snorted in response, and Curtis, smiling in the dark, threw his arm across her neck in fellowship and said, “Feels good, doesn’t it, Betty B., to get out of that hurricane from hell?”

By the light of a lantern he led the mare to the spring, stabling her afterward in one of the houses. “In the best society, Betty Brown,” he explained, “it’s not considered good form for horses to sleep in men’s houses. But you deserve the best I can give you to-night, blest if you don’t, old girl, and you shall have it, too.” He gathered together, for her food and her bed, the alfalfa hay from several of the bunks, and found for her also a small measure of oats. Then, having attended to her wants, he looked about for something to stay his own hunger.

It was his custom to keep some canned provisions in the place, as the station was much used by his men. On a little smouldering fire in one corner of the room, he made some tea in a tin can. A frying-pan hung against the wall, and in it, awkwardly fumbling with his one useful hand, he contrived to warm a stew of tinned chile con carne and pilot bread. Fine sand drifted in and settled in a red dust over the food as he ate, and he could feel its grit between his teeth.

The bird he had carried in his bosom he found to be a Southwestern tanager. Its pinkish-red plumage shone with a silvery radiance in the lamplight. One of its legs was broken, and one wing had been injured. “I’ll take it to Miss Bancroft,” he said aloud, “and she’ll care for it till it can shift for itself again, poor little devil!”
