"Yes, mother. I know it."

"How did it come?"

"I don't know."

"You'll never get along, Diana, till you know everything that happens in your house. You aren't fit anyhow to be a poor woman. If you're rich, why you can get a new pane of glass, and there's the end of it. I'm not so rich as all that comes to."

"Getting a pane of glass, mother?"

"Without knowing what for."

"But how does it help the matter to know what for? The glass must be got anyway."

"If you know what for, it won't be to do another time. You'll find a way to stop it. I'll warrant, now, Diana, you haven't had the ashes cleared out of that stove for a week."

"Why, mother?"

"It smokes. It always does smoke when it gets full of ashes; and it never smokes when it ain't."
