"Oh, but you don't know how awfully hard that'll be to do," I said tearfully; "our banisters are so broad and smooth, and one goes so swiftly down them,—almost like flying—"

"I don't suppose it will be easy to give up the habit," broke in Nannie, wiping my eyes with her handkerchief; "but all the same, Miss Elizabeth, I am confident that if you really make up your mind to stop sliding, you'll do it. You can't keep up such a tomboyish trick all your life, and now is a good time to begin, I think. Dear mamma used to say that everybody had to have some responsibility or other; why not begin to take up yours now? Helen Vassah is only about six months older than you are, and here she has the responsibility of being little Paul's godmother. And there's Hope Unsworth a little younger than you; you know how she helps her grandmother in her charitable work. They are certainly not 'prim or proper;' they are full of fun, yet they wouldn't either of them ever think of doing the rough things that you do,—now would they?"

I had to admit that I knew they wouldn't.

"Then," said Nannie, "don't you do them either. Take yourself as your responsibility, and show us what you can accomplish in that line. Will you, dearie?" She snuggled her head close up to mine on the pillow as she said this.

"Oh, dear!" I sighed, "I do wish Jack had been I, and I'd been Jack!"

"Even then you would have had to stop such childish tricks some time or other before you grew up. With all his larks, Phil doesn't do them; and think of papa's coming down to breakfast on the banisters!" Nannie and I had to laugh at the very thought.

"Well," I said presently, "perhaps I'll try; but that conceited boy'll think he's made me do it."

"Oh, no, he won't!" Nannie said, in a tone of conviction that was very comforting. "If he does think now that you're inclined to be a hoiden, why, he'll soon change his mind, when he finds what a nice, sweet little lady you are from day to day. Don't look so dismal, Miss Elizabeth; there's lots of fun left for you!"

"I'll try; but I know I'll forget, time and again," I said, sighing heavily.

"I don't think there'll be so very many slips," Nannie answered cheerfully; "but if there should be, we'll just do as Rip Van Winkle did,—'we won't count' them."
