"Yes. Well—you shall. And you shall not study for it neither; which you can't."
"Yes I can."
"No you can't. You are no more fit for it, little Daisy—but look here!
I wish you would be a red daisy."
"Then what else, Preston?"
"Nothing else. Geography is enough at once."
"O no, it isn't. Preston, I can't do the least little bit of a sum in the world."
"Can't you? Well—I don't see that that is of any very great consequence. What sums do you want to do?"
"But I want to know how."
"Why?"
"Why Preston, you know I ought to know how. It might be very useful, and I ought to know."
