Louise hesitated for a moment. The doctor had asked her for this very waltz; but already the room was full of moving couples, and she could see him dancing with the pretty young teacher, lately come from the East. With a little feeling of pique she turned to her escort, and was soon gliding about the room with an apparent delight in her partner, who was dancing quite as well as he had talked. The waltz ended, she turned away, without a glance at the neglectful doctor, and followed her new acquaintance to their former seats in the hall. "How well you waltz!" she said frankly, as she fanned herself. "It's such a rare thing to meet a really good dancer out here." "Such a partner would inspire anyone," returned her companion gallantly, while he twirled his mustache with a complacent delight in it which convinced Louise that it was of recent growth. Then he entered into a spirited account of his journey and his adventures in coming into the strange place, while Louise sat leaning back in her chair, watching him, haunted by that vague resemblance. Dr. Brownlee was standing just inside the parlor door with his eyes fixed upon them longingly, although he was apparently engrossed by the sprightly conversation of his former partner. But Mr. Atherden made no motion as if to leave his place; he merely glared defiantly at the doctor, while he twisted his mustache and chatted on, and the doctor was forced to go away again. Notwithstanding her apparent unconsciousness of his presence, Louise had looked after him with a little wistful expression in her blue eyes. At that moment, she heard a sudden exclamation, and she turned back to face her companion once more, just in time to see the silky brown mustache yield to too violent a jerk and fall into his lap, while the young man, in no wise embarrassed by the accident, leaned back in his chair and burst into a shout of laughter. One glance at him had told her the secret of the puzzling resemblance; and she echoed his laugh with a thorough enjoyment of the boyish caper. "Charlie MacGregor, you incorrigible imp!" she exclaimed, when she could get her breath. "How did you ever dare to come here in this fashion?" "Why not?" inquired Charlie. "You'd never have known me now, if this miserable mustache had only stuck where it belonged. But, honestly, Miss Lou, don't I make a fair actor?" "Too good, Charlie," she answered, with a fresh laugh over the unexpected ending to her flirtation. "Why haven't you ever told us you could waltz so well, though?" "I didn't suppose I could; it's so long since I've tried it. Besides, none of the other fellows do, and I was afraid they'd think 'twas silly for a boy," answered Charlie. "Allie started this scheme, and put on the finishing touches. But didn't you really know me, Miss Lou?" "Not a bit. Nobody would ever have suspected, if you hadn't been quite so proud of your mustache, Mr. Atherden. By the way, where did you get the name?"
