She rode out into an open space where a loose earth-slide denied lodgement to trees and grass. She halted the horse at the brink of the slide and glanced down it with a measuring eye. Forty feet beneath, the slide terminated in a small, firm-surfaced terrace, the banked accumulation of fallen earth and gravel. “It’s a good test,” she called across the canyon. “I’m going to put him down it.” The animal gingerly launched himself on the treacherous footing, irregularly losing and gaining his hind feet, keeping his fore legs stiff, and steadily and calmly, without panic or nervousness, extricating the fore feet as fast as they sank too deep into the sliding earth that surged along in a wave before him. When the firm footing at the bottom was reached, he strode out on the little terrace with a quickness and springiness of gait and with glintings of muscular fires that gave the lie to the calm deliberation of his movements on the slide. “Bravo!” Chris shouted across the canyon, clapping his hands. “The wisest-footed, clearest-headed horse I ever saw,” Lute called back, as she turned the animal to the side and dropped down a broken slope of rubble and into the trees again. Chris followed her by the sound of her progress, and by occasional glimpses where the foliage was more open, as she zigzagged down the steep and trailless descent. She emerged below him at the rugged rim of the torrent, dropped the horse down a three-foot wall, and halted to study the crossing. Four feet out in the stream, a narrow ledge thrust above the surface of the water. Beyond the ledge boiled an angry pool. But to the left, from the ledge, and several feet lower, was a tiny bed of gravel. A giant boulder prevented direct access to the gravel bed. The only way to gain it was by first leaping to the ledge of rock. She studied it carefully, and the tightening of her bridle-arm advertised that she had made up her mind. Chris, in his anxiety, had sat up to observe more closely what she meditated. “Don’t tackle it,” he called. “I have faith in Comanche,” she called in return. “He can’t make that side-jump to the gravel,” Chris warned. “He’ll never keep his legs. He’ll topple over into the pool. Not one horse in a thousand could do that stunt.” “And Comanche is that very horse,” she answered. “Watch him.” She gave the animal his head, and he leaped cleanly and accurately to the ledge, striking with feet close together on the narrow space. On the instant he struck, Lute lightly touched his neck with the rein, impelling him to the left; and in that instant, tottering on the insecure footing, with front feet slipping over into the pool beyond, he lifted on his hind legs, with a half turn, sprang to the left, and dropped squarely down to the tiny gravel bed. An easy jump brought him across the stream, and Lute angled him up the bank and halted before her lover. “Well?” she asked. “I am all tense,” Chris answered. “I was holding my breath.”
