Neither Zeke nor George had a word in reply. Hare thought their silence unnatural. Neither did the mask-like stillness of their faces change. But Hare saw in their eyes a pointed clear flame, vibrating like a compass-needle, a mere glimmering spark. “I'd like to know,” continued Dave, calmly poking the fire, “who hired Dene's men to plug the waterhole. Dene couldn't do that. He loves a horse, and any man who loves a horse couldn't fill a waterhole in this desert.” Hare entered upon his new duties as a range-rider with a zeal that almost made up for his lack of experience; he bade fair to develop into a right-hand man for Dave, under whose watchful eye he worked. His natural qualifications were soon shown; he could ride, though his seat was awkward and clumsy compared to that of the desert rangers, a fault that Dave said would correct itself as time fitted him close to the saddle and to the swing of his horse. His sight had become extraordinarily keen for a new-comer on the ranges, and when experience had taught him the land-marks, the trails, the distances, the difference between smoke and dust and haze, when he could distinguish a band of mustangs from cattle, and range-riders from outlaws or Indians; in a word, when he had learned to know what it was that he saw, to trust his judgment, he would have acquired the basic feature of a rider's training. But he showed no gift for the lasso, that other essential requirement of his new calling. “It's funny,” said Dave, patiently, “you can't get the hang of it. Maybe it's born in a fellow. Now handling a gun seems to come natural for some fellows, and you're one of them. If only you could get the rope away as quick as you can throw your gun!” Jack kept faithfully at it, unmindful of defeats, often chagrined when he missed some easy opportunity. Not improbably he might have failed altogether if he had been riding an ordinary horse, or if he had to try roping from a fiery mustang. But Silvermane was as intelligent as he was beautiful and fleet. The horse learned rapidly the agile turns and sudden stops necessary, and as for free running he never got enough. Out on the range Silvermane always had his head up and watched; his life had been spent in watching; he saw cattle, riders, mustangs, deer, coyotes, every moving thing. So that Hare, in the chasing of a cow, had but to start Silvermane, and then he could devote himself to the handling of his rope. It took him ten times longer to lasso the cow than it took Silvermane to head the animal. Dave laughed at some of Jack's exploits, encouraged him often, praised his intent if not his deed; and always after a run nodded at Silvermane in mute admiration.
