"I wonder how many girls Will Morrow's said that to this afternoon!" came like a sarcastic douche from Sissy, who conceived it to be a chaperon's duty to take the conceit out of citified chaps. Young Morrow turned to find a small woman in brown eying him disdainfully. "Well--well, I never said it to you, anyway," he retorted gallantly. "Good reason why. You knew I wouldn't believe you," Sissy declared, floundering in her anger. "Neither would anybody else." [Illustration: "The Belle of the Afternoon"] "Why? Because you said it? Didn't know you had such a reputation." Sissy was recovering. "Never mind, Split," she added, heavily sarcastic and assuming a comforting air that maddened Irene, who desired nothing more than to impress her new suitor with the elegant gentility of her manner, her family's, and all that was hers. "Just to have a boy from the city even pretend to think you're good-looking is worth living for. Boys know so much--in the city!" she concluded witheringly. Mr. Morrow from San Francisco looked bewildered. He had merely paid what he considered a very dashing compliment to one girl, when lo! the other overwhelmed him with her contempt. He turned for consolation to Irene. "I'll show you how they dance the two-step in the city," he said, holding out his hand as the music began again. But he had reckoned without that stern censor of sisterly manners, Cecilia Madigan; that loyal Comstocker who resented the implication of her town's inferiority, quite independent of the fact that the insult was not addressed to her but to one who, apparently, welcomed it. "I think I'll go home now, Split," she remarked carelessly, rising. A sudden blight fell upon the belle of the afternoon. When Sissy went, go she must, too; this was the sole rule of conduct Francis Madigan had devised for the guidance of his most headstrong daughter. "Oh, Sissy--not till after supper!" she pleaded piteously. "I--I've got some studying to do for the examination Monday," explained the exemplary member of Mr. Garvan's class and society at large. "Just wait till this one dance is over!" Coaxing was not Split Madigan's forte; she was accustomed to demand. But it was just that one dance that Sissy, the pure and patriotic, could not countenance. A quick flash of fury lighted Irene's eye. To be bossed publicly and before Mr. Will Morrow of San Francisco! In her heart she swore to be avenged; yet she dropped Mr. Morrow's hand and shook her head to all his pleadings, as she followed her ruthless tyrant across the floor to the little dressing-room. But as the sisters emerged from the dressing-room door, Crosby Pemberton and his cousin Fred stopped them. "You're not going home, Split?" begged Fred. "I've been looking everywhere for you. Oh, come and dance just this one with me!" "Sissy's going," said Split, the lilting of the music stirring her pulses and lifting her feet, despite the unmusical rage she was in, "and I've got to go, too."
