Rosa's eyes, dimples, pink cheeks, and coquettish little mouth were not idle in these days. She knew how to have every pupil at her feet and ready to obey her slightest wish. She wielded her power to its fullest extent as the summer drew near, and day after day saw a slow torture for Margaret. Some days the menacing air of insurrection fairly bristled in the room, and Margaret could not understand how some of her most devoted followers seemed to be in the forefront of battle, until one day she looked up quickly and caught the lynx-eyed glance of Rosa as she turned from smiling at the boys in the back seat. Then she understood. Rosa had cast her spell upon the boys, and they were acting under it and not of their own clear judgment. It was the world-old battle of sex, of woman against woman for the winning of the man to do her will. Margaret, using all the charm of her lovely personality to uphold standards of right, truth, purity, high living, and earnest thinking; Rosa striving with her impish beauty to lure them into _any_ mischief so it foiled the other's purposes. And one day Margaret faced the girl alone, looking steadily into her eyes with sad, searching gaze, and almost a yearning to try to lead the pretty child to finer things. "Rosa, why do you always act as if I were your enemy?" she said, sadly. "Because you are!" said Rosa, with a toss of her independent head. "Indeed I'm not, dear child," she said, putting out her hand to lay it on the girl's shoulder kindly. "I want to be your friend." "I'm not a child!" snapped Rosa, jerking her shoulder angrily away; "and you can _never_ be my friend, because I _hate_ you!" "Rosa, look here!" said Margaret, following the girl toward the door, the color rising in her cheeks and a desire growing in her heart to conquer this poor, passionate creature and win her for better things. "Rosa, I cannot have you say such things. Tell me why you hate me? What have I done that you should feel that way? I'm sure if we should talk it over we might come to some better understanding." Rosa stood defiant in the doorway. "We could never come to any better understanding, Miss Earle," she declared in a cold, hard tone, "because I understand you now and I hate you. You tried your best to get my friend away from me, but you couldn't do it; and you would like to keep me from having any boy friends at all, but you can't do that, either. You think you are very popular, but you'll find out I always do what I like, and you needn't try to stop me. I don't have to come to school unless I choose, and as long as I don't break your rules you have no complaint coming; but you needn't think you can pull the wool over my eyes the way you do the others by pretending to be friends. I won't be friends! I hate you!" And Rosa turned grandly and marched out of the school-house.
