Far back on the west end of the northern chain of hills a Mexican collapsed his telescope, hazarded a long-range shot at the hard-riding Charley and, mounting in haste, sped to carry disturbing news to his employer. The courier looked around as the singing lead raised a puff of dust in front of him, snarled in the direction from whence he thought it had come and, having no time for personal grievances, leaned forward and quirted the horse to greater speed. Whirring across the Diamond L range Charley caused another Mexican, watching from a ridge overlooking the ranch buildings, to run to the waiting horse and mount it, after which he delayed his departure until he saw the Diamond L outfit string out into a race for town, whereupon he set a pace which promised to hold him his generous lead. In Mesquite a Mexican quirted a lathered horse for a final burst of speed up the quiet street, flung himself through Kane's front door, shouted a warning as he scrambled to his feet and dashed through the partition door to make his report direct to his boss. As he bolted out of sight behind the partition, other men popped from the building like weasel-pursued rabbits from a warren and scurried over the town to spread the alarm to those who were most vitally concerned by it. Two streams forthwith flowed over their trails, the first and larger heading for Kane's; the other, composed entirely of Mexicans, flowed toward Red Frank's, which had been allotted the rôle of outlying redoubt, to help keep harmless the broken ground between it and Kane's front wall, and was now being put in shape to withstand a siege.
