your sense of proportion. Do you know what proportion means?"
"Oh, yes, papa, I studied 'ratio and proportion' in arithmetic."
"Not that kind," said her father, smiling; "I mean a proportion of human interests, of amusements or occupations. I wonder if you are too young to understand."
"No, I'm not too young to understand anything," said Patty, fairly blinking in her endeavor to look as wise as an owl.
"Well, then, listen while I put it this way. Suppose you were to make a cake, an ordinary sized cake, you know, how much yeast would you put in it?"
"Not any, papa," said Patty, laughing merrily. "I know enough housekeeping not to put yeast in a cake. I'd use baking-powder."
"Yes," said her father, quite undisturbed, "that is what I meant,—baking-powder. Now how much of it would you use?"
"Well, about two teaspoonfuls," said Patty, feeling very important and housewifely.
"Yes. Now suppose instead of two teaspoonfuls you put in two cupfuls."
