the spring mended to-morrow. There is no good in having an uncomfortable bed; but for to-night it does not matter.”

“Oh, I see you are going to be good-natured! That is your screen—you can take the best of the two, because I never open mine. You can paste any pictures you like on it if you are given that way; but I hope to goodness you are not. The screen is to put round your washhand-stand. That is your table, and that is your chest of drawers. Now, for goodness’ sake, like a dear, good creature, put your things in order, and don’t speak to me again. I must go on with my calculus of finite differences.”

“What do you mean?” asked Leslie.

“Do you wish for an explanation? If so, pray sit down opposite to me and don’t expect to stir for a week; it will take me at least as long to explain the matter. Oh, don’t say any more just now, and do move as softly as you can! Do just consider that my winning honors in mathematics is a little more important than that your drawers should be in immaculate order. Do you comprehend?”

“Perfectly.”

“Well, don’t say another word.”

The red-haired maiden returned to her desk, stuffed both her hands through her fiery locks, which stuck out now like great wings on each side of her head, and began murmuring slowly to herself.

Leslie stood still for a moment with a sense of dismay stealing over her.

“What is to be done?” she thought. “Miss Colchester is a very peculiar girl. What does a calculus of finite differences mean? I almost wish dear old Lew had been mathematical, then perhaps I should have known.

Well, never mind; I won’t disturb that poor, dear scholarly girl; but unpack my things I simply must.”
