Elsie looked at papa, and papa looked at Elsie. Dr. Carr's eyes twinkled just a little, but otherwise he was perfectly grave. Elsie began to speak, then to laugh, then to cry, and the explanation, when it came, was given in a mingled burst of all three. "O papa, it was horrid! That is, Mrs. Worrett was just as kind as could be, but so fat; and oh, such a pig! I never imagined such a pig! And the calico on that horrid sofa was so slippery that I rolled off five times, and once I hurt myself real badly. And we had a feather-bed; and I was so homesick that I cried all the evening." "That must have been gratifying to Mrs. Worrett," put in Dr. Carr. "Oh! she didn't know it, papa. She was asleep, and snoring so that nobody could hear. And the flies!--such flies, Katy!--and the mosquitoes, and our window wouldn't open till I put in a nail. I am so glad to get home! I never want to go into the country again, never, never! Oh, if Alexander hadn't come!--why, Clover, what are you laughing for? And Dorry,--I think it's very unkind," and Elsie ran to Katy, hid her face, and began to cry. "Never mind, darling, they didn't mean to be unkind. Papa, her hands are quite hot; you must give her something." Katy's voice shook a little; but she would not hurt Elsie's feeling by showing that she was amused. Papa gave Elsie "something" before she went to bed,-- a very mild dose I fancy; for doctors' little girls, as a general rule, do not take medicine, and next day she was much better. As the adventures of the Conic Section visit leaked out bit by bit, the family laughed till it seemed as if they would never stop. Phil was forever enacting the pig, standing on his triumphant hind legs, and patting Elsie's head with his nose; and many and many a time, "It will end like your visit to Mrs. Worrett," proved a useful check when Elsie was in a self-willed mood and bent on some scheme which for the moment struck her as delightful. For one of the good things about our childish mistakes is, that each one teaches us something; and so, blundering on, we grow wiser, till, when the time comes, we are ready to take our places among the wonderful grown-up people who never make mistakes.
