But when the gentle Mistress Sepulvida was within a hundred yards of the Point she expected to round, she saw with some chagrin that the tide was up, and that each dash of the breaking seas sent a thin, reaching film of shining water up to the very roots of the pines. To her still further discomfiture, she saw also that a smart-looking cavalier had likewise reined in his horse on the other side of the Point, and was evidently watching her movements with great interest, and, as she feared, with some amusement. To go back would be to be followed by this stranger, and to meet the cynical but respectful observation of Concho; to go forward, at the worst, could only be a slight wetting, and a canter beyond the reach of observation of the stranger, who could not in decency turn back after her. All this Donna Maria saw with the swiftness of feminine intuition, and, without apparently any hesitation in her face of her intent, dashed into the surf below the Point. Alas for feminine logic! Mistress Sepulvida's reasoning was perfect, but her premises were wrong. Tita's first dash was a brave one, and carried her half round the Point, the next was a simple flounder; the next struggle sunk her to her knees, the next to her haunches. She was in a quicksand! "Let the horse go. Don't struggle! Take the end of your riata. Throw yourself flat on the next wave, and let it take you out to sea!" Donna Maria mechanically loosed the coil of hair rope which hung over the pommel of her saddle. Then she looked around in the direction of the voice. But she saw only a riderless horse, moving slowly along the Point. "Quick! Now then!" The voice was seaward now; where, to her frightened fancy, some one appeared to be swimming. Donna Maria hesitated no longer; with the recoil of the next wave, she threw herself forward and was carried floating a few yards, and dropped again on the treacherous sand. "Don't move, but keep your grip on the riata!" The next wave would have carried her back, but she began to comprehend, and, assisted by the yielding sand, held her own and her breath until the under-tow sucked her a few yards seaward; the sand was firmer now; she floated a few yards farther, when her arm was seized; she was conscious of being impelled swiftly through the water, of being dragged out of the surge, of all her back hair coming down, that she had left her boots behind her in the quicksand, that her rescuer was a stranger, and a young man--and then she fainted. When she opened her brown eyes again she was lying on the dry sand beyond the Point, and the young man was on the beach below her, holding both the horses--his own and Tita! "I took the opportunity of getting your horse out. Relieved of your weight, and loosened by the tide, he got his foot over the riata, and Charley and I pulled him out. If I am not mistaken, this is Mrs. Sepulvida?" Donna Maria assented in surprise.
