"She doesn't understand girls," she grumbled to herself. "I don't believe she ever was a girl herself. She must have been born about forty, with spectacles and a cap. I can't think why she wants to see me. I do nothing but say `Yes' and `No' while she abuses other people, and yawn my head off in that stifling room. And I did so want to get on with my blouse. Seems as if I could never do as I like, somehow!" She sat looking such an image of meekness and resignation, with her smoothly-braided locks and downcast lids, that her father's lips twitched with amusement as he glanced at her, and quickly averted his eyes. He knew just as well as she did how distasteful his request had been, but he was none the less anxious to enforce it. Betty's horizon was blocked with self at the present moment, and anything and everything was of gain which forced her to think of something besides that all- important personage Miss Elizabeth Trevor. CHAPTER FOUR. A PIECE OF LOOKING-GLASS. "Such a joke, Jill! The sun is shining, and the Pet is sitting reading, in the drawing-room window, and I've found a broken piece of looking- glass in the street.--There's luck! Let's hide behind the curtains and flash it in her eyes!" Jill's book fell down with a crash, and she leapt to her feet, abeam with anticipation. It was Saturday, and she had announced her intention of "stewing hard" all the afternoon, but the claims of examinations sank into the background before the thrilling prospect held out by her twin. "Break it in two! Fair does, Jack! Give me a bit, and let us flash in turns!" she cried eagerly; but Jack would not consent to anything so rash. "How can I divide it, silly?" he replied. "I haven't a diamond _to cut it_, and if I crunch it with my foot it may all go to smithereens, and there will be nothing left. I'll lend it to you for a bit now and then, but you won't aim straight. Girls never do!" "I do! I do!" Jill maintained loudly. "I will! I will! Come along, be quick! She might move away, and it would be such a sell. I'll kneel down here and keep the curtains round me. I wonder what she's reading. Something awfully dry and proper, I expect! What heaps of hair! It hangs over her face, so that we shan't be able to dazzle her a bit." "Yes, we will," contradicted Jack. "She'll see the light dancing about on the page, and look up to see what's the matter! You watch, but mind you don't bob up your head and let her see you!" "Mind you don't let her see your hand! It's sticking right out. You ought to put on a dark glove, which she wouldn't notice against the pane."
