Her eyes upon the girl's averted face, Persis measured off the coarse stuff, using her arm as a yard-stick. "Hm! Even with skirts as skimpy as they are now, this won't be enough by a yard and a half. Better call it two yards. It's high time your skirts were coming down where they belong. You can't stay a little girl forever." Some magic had erased the fretful pucker between Diantha's brows. The grim ungirlish compression of her lips softened into angelic mildness. As she turned upon Persis, she looked an older sister of the Sistine cherubs. "How long--about how long do you think it had better be, Miss Persis?" "I should say"--Persis looked her over with an impersonal air, lending weight to the resulting judgment--"I should say about to your shoe-tops." Had she guessed the consequences of such an expression of opinion, she might have modified her verdict or at least held it in reserve. A tempest swept the room. Persis was seized, whirled this way and then that, hugged, kissed, forced to join in a delirious two-step. With scarcely breath to protest, powerless in the grip of the storm she had herself evoked, she finally came to anchor between the secretary and the armchair, Diantha still holding her fast. "Shoe-tops! You _did_ say shoe-tops, didn't you, darling Miss Persis?" "Yes, I said shoe-tops, and I'm glad I didn't say a train. A real long dress would have been the death of me, it's more'n likely. For all you're as tall as Jack's bean-stalk, Diantha Sinclair, you're not grown up yet." Persis freed herself, smiling ruefully as she arranged her disordered hair. The delicious girlishness of the outburst in which she had involuntarily participated had the effect of challenging her own obstinate sense of being on the threshold of things, and making her wonder if perhaps she were not growing old. That the passing shadow on her face failed to attract Diantha's attention was due less to lack of insight than to youth's cheerfully selfish absorption in its own problems. "May I pick out the style from the grown-up part of the fashion books?" was the girl's breathless question. "It's got to be simple," Persis warned her sternly. Then softening: "But good land! Grandmothers nowadays are wearing simple little girlish things with ribbon bows in the back. Pick out what you want. Everything in this month's book is just about right for sixteen." As Diantha gave herself to rapturous study of the fashion-plates, Persis studied her. "She's in a fair way to make a beauty. Annabel at her best never held a candle to what this girl is likely to turn out. Annabel's looks are skin deep. Diantha's have top-roots running to her brain and her heart, too. Only she ought to be happier. 'Most any girl face is pretty to look at if it's happy enough, same as 'most any flower is pretty if it grows in the sun." A harassing reflection troubled Diantha's bliss. "Miss Persis, I haven't got a petticoat that comes below my knees."
