Another Sunday man and horse and dog roved the Piedmont hills. And again Daylight and Dede rode together. But this time her surprise at meeting him was tinctured with suspicion; or rather, her surprise was of another order. The previous Sunday had been quite accidental, but his appearing a second time among her favorite haunts hinted of more than the fortuitous. Daylight was made to feel that she suspected him, and he, remembering that he had seen a big rock quarry near Blair Park, stated offhand that he was thinking of buying it. His one-time investment in a brickyard had put the idea into his head--an idea that he decided was a good one, for it enabled him to suggest that she ride along with him to inspect the quarry. So several hours he spent in her company, in which she was much the same girl as before, natural, unaffected, lighthearted, smiling and laughing, a good fellow, talking horses with unflagging enthusiasm, making friends with the crusty-tempered Wolf, and expressing the desire to ride Bob, whom she declared she was more in love with than ever. At this last Daylight demurred. Bob was full of dangerous tricks, and he wouldn't trust any one on him except his worst enemy. "You think, because I'm a girl, that I don't know anything about horses," she flashed back. "But I've been thrown off and bucked off enough not to be over-confident. And I'm not a fool. I wouldn't get on a bucking horse. I've learned better. And I'm not afraid of any other kind. And you say yourself that Bob doesn't buck." "But you've never seen him cutting up didoes," Daylight said. "But you must remember I've seen a few others, and I've been on several of them myself. I brought Mab here to electric cars, locomotives, and automobiles. She was a raw range colt when she came to me. Broken to saddle that was all. Besides, I won't hurt your horse." Against his better judgment, Daylight gave in, and, on an unfrequented stretch of road, changed saddles and bridles. "Remember, he's greased lightning," he warned, as he helped her to mount. She nodded, while Bob pricked up his ears to the knowledge that he had a strange rider on his back. The fun came quickly enough--too quickly for Dede, who found herself against Bob's neck as he pivoted around and bolted the other way. Daylight followed on her horse and watched. He saw her check the animal quickly to a standstill, and immediately, with rein across neck and a decisive prod of the left spur, whirl him back the way he had come and almost as swiftly. "Get ready to give him the quirt on the nose," Daylight called.
