No one spoke as Pat climbed heavily back to his seat. For two miles the tracks of the strange horse were visible, then they were blotted out by the sand that had filled them. "He made that much since the blow," was Texas' slow comment. "How far we are from where he started is all guess." As they pushed on, all eyes searched the country eagerly and before long they found the spot for which they looked. A light spring wagon with a piece of a halter strap tied to one of the wheels was more than half-buried by the sand in the lee of a high drift. There was a small water keg, empty, with its seams already beginning to open in the fierce heat of the sun, a "grub-box," some bedding and part of a bale of hay-nothing more. Jefferson Worth, Pat and the boy attempted to dig in the steep side of the drift that rose above the half-buried outfit, but at their every movement tons of the dry sand came sliding down upon them. "It ain't no use, Mr. Worth," said Texas, as the banker straightened up, baffled in his effort. "You will never know what's buried in there until God Almighty uncovers it." Then the man of the desert and plains read the story of the tragedy as though he had been an eye witness. "They was travelin' light an' counted on makin' good time. They must have counted, too, on, findin' water in the hole." He kicked the empty keg. "Their supply give out an' then that sand-storm caught 'em and the horses broke loose. Of course they would go to hunt their stock, not darin' to be left afoot and without water, an' hits a thousand to one they never got back to the outfit. We're takin' too many chances ourselves to lose much time and I don't reckon there's any use, but we'd better look around maybe." He directed the little party to scatter and to keep on the high ground so that they would not lose sight of each other. Until well on in the afternoon they searched the vicinity, but with no reward, while the hot sun, the dry burning waste and the glaring sands of the desert warned them that every hour's delay might mean their own death. When they returned at last to the wagon, called in by Texas, no one spoke. As they went on their way each was busy with his own thoughts of the grim evidence of the desert's power. Another hour passed. Suddenly Texas halted the mules and, with an exclamation, leaped to the ground. The others saw that he was bending over a dim track in the sand. "My God! men," he shouted, "hit's a woman." For a short way he followed the foot-prints, then, running back to the wagon and springing to his seat, swung his long whip and urged the team ahead. "Hit's a woman," he repeated. "When the others went away and didn't come back she started ahead in the storm alone. She had got this far when the blow quit, leavin' her tracks to show. We may--" He urged his mules to greater effort.
