The two horses picked their way carefully downward over the loose shale of the steep hillside. The big bay stallion in the lead sidled mincingly, tossing his head nervously, and flecking the flannel shirt of his rider with foam. Behind the man on the stallion a girl rode a clean-limbed bay of lighter colour, whose method of descent, while less showy, was safer, for he came more slowly, and in the very bad places he braced his four feet forward and slid down, sometimes almost sitting upon the ground.At the base of the hill there was a narrow level strip; then an eight-foot wash, with steep banks, barred the way to the opposite side of the canyon, which rose gently to the hills beyond. At the foot of the descent the man reined in and waited until the girl was safely down; then he wheeled his mount and trotted toward the wash. Twenty feet from it he gave the animal its head and a word. The horse broke into a gallop, took off at the edge of the wash, and cleared it so effortlessly as almost to give the impression of flying.Behind the man came the girl, but her horse came at the wash with a rush-not the slow, steady gallop of the stallion-and at the very brink he stopped to gather himself. The dry bank caved beneath his front feet, and into the wash he went, head first.The man turned and spurred back. The girl looked up from her saddle, making a wry face."No damage?" he asked, an expression of concern upon his face."No damage," the girl replied. "Senator is clumsy enough at jumping, but no matter what happens he always lights on his feet.""Ride down a bit," said the man. "There's an easy way out just below."She moved off in the direction he indicated, her horse picking his way among the loose boulders in the wash bottom."Mother says he's part cat," she remarked. "I wish he could jump like the Apache!"The man stroked the glossy neck of his own mount."He never will," he said. "He's afraid. The Apache is absolutely fearless; he'd go anywhere I'd ride him. He's been mired with me twice, but he never refuses a wet spot; and that's a test, I say, of a horse's courage."They had reached a place where the bank was broken down, and the girl's horse scrambled from the wash."Maybe he's like his rider," suggested the girl, looking at the Apache; "brave, but reckless.""It was worse than reckless," said the man. "It was asinine. I shouldn't have led you over the jump when I know how badly Senator jumps.""And you wouldn't have, Custer,"-she hesitated-" if-""If I hadn't been drinking," he finished for her. "I know what you were going to say, Grace; but I think you're wrong. I never drink enough to show it. No one ever saw me that way-not so that it was noticeable.""It is always noticeable to me and to your mother," she corrected him gently. "We always know it, Custer. It shows in little things like what you did just now. Oh, it isn't anything. I know, dear; but we who love you wish you didn't do it quite so often. ""It's funny," he said, "but I never cared for it until it became a risky thing to get it. Oh, well, what's the use? I'll quit it if you say so. It hasn't any hold on me."
