So the winter passed quietly and swiftly away; for busy time is always swift time, and all three of our Olmstead household were thoroughly busy: Sara with her writing added to the museum work; Morton with his studies, in which he was growing deeply interested; and Molly in a little of everything. She had no special fondness for books, but a real genius for cookery and housework, most of which now devolved upon her in their modest establishment. But Molly was growing very pretty too, not with Sara's delicate, spirituelle attractions, but with a saucy, piquant, bewitching charm of her own that the students were not slow to notice, and which Molly was not slow to appreciate, and make the most of.

Still, Sara did not for some time take any notice of this; for she could not understand that what to her was a nuisance, and to be gotten rid of at once, was to Molly the source of the greatest amusement and delight, —their street admiration and attentions. It came upon her with a shock, one day, to find herself on the sidewalk behind some tall-hatted young sprig, accompanied by her little sister, rattling on to him with smiles, dimples, and tosses, in her own peculiar way, as if she had known him all her life, and she could scarcely wait to get the child indoors, before she began,—

"Molly, who was that?"

"That? Why, I've forgotten his name," coolly. "He's a 'fresh' though, I believe."

"And you're one, too, I should think!" strongly indignant. "What in the world were you doing?"

"Oh, just talking and laughing."

"When you don't even know who he is? O Molly!"

"Well, what of it? All the girls talk to them, coming home from school, and nobody thinks anything of it but you!" pouting and frowning, in her growing anger.

Sara looked at her with suddenly-awakened eyes. Even in her petulance she was wonderfully pretty, with her great surprised eyes, saucy little nose, and exquisite coloring; and a sudden sense of her helplessness, if this little sister should also prove to be vain, and careless of her good name, came over her with such crushing force that she dropped into a chair, feeling almost faint for the moment. Molly, frightened at her sudden pallor, cried out,—

"What is it, Sara? What have I done? Is it such a sin to walk with a student on the street?"
