It was a big load for the buckboard with Mormon and Sam in the back seat crowded by the piled-up baggage, with Sandy driving and Molly beside him, flushed a little with growing excitement. But the buckskins were sinewed with whalebone and used to desert work. They surged forward at the word, tightening the tugs in an eager leap and settled down to a fast trot, out across the prairie. The riders, with the exception of Buck, and Jim, who was already close to the butte, which was midway between the ranch and Hereford, loped off, two and two, to their work, not to return until sun-down. It was still cool, the dust rose about them in eddies as they crossed the slowly descending slope of the sink that presently mounted again toward the far-off range. There was no apparent road, but Sandy chose a compass course between the sage for the first few miles, then skirted the mesquite. Sam leaned forward once when the buckskins had been pulled down to a walk and spoke to Molly. "See that notch in the range?" he asked, "oveh to the no'th, where the shadder's blue. That's Paso Cabras, the Pass of the Goats. Some says it's named 'cause the cliffs is fair lousy with goats, some 'cause on'y a goat can make the climb. County line's five mile' out on the plain beyond the pass. Railroad two mo', at Caroca." "Are we goin' through the pass?" she asked Sandy. "Well, I'll tell you this much, Molly. If we sh'ud decide to go that way an' strike the pass afore the sheriff catches up with us, he'll have to foller afoot or go clean round the mesa. The Goat's Pass ain't no place fo' an automobeel, nor an airyplane neither. Don't believe there's a level spot wider'n five foot or bigger than that much square." Either Mormon or Sam sat always with neck twisted, watching for a flash-signal from the butte that stood up clearly in the crystal atmosphere, sometimes distorted, changing hue from chocolate to indigo, never seeming to get any farther away, just as the mesa range never seemed to get any closer. Sometimes Molly relieved them as lookout, but hour after hour passed without sign. Close to noon they reached a watering hole, with water none too cool or sweet, but still welcome. There the buckskins were unhitched, rubbed down and, after they had cooled off, given water and grain. Save for sweat marks, they showed little sign of the grueling trip through the soft dirt. A strip of lava, half a mile of ancient flow, lay between them and the long up-slope of the desert to the mesa. As they ate lunch in the shadow of some barrel cactus, Sandy suddenly gave a grunt of satisfaction, pointing with outstretched forefinger to the butte. Five flashes had flickered up. They were repeated. Jim had signaled a suspicious party on their way to Three Star. The sheriff was out with his papers.
