"Nonsense," said the Unwiseman. "A vocabulary is nothing of the sort. It's a—a sort of little bureau talkers have to keep their words in. It's a sort of word-cabinet. I haven't really got one, but that's because I don't need one. I have so few words I can carry them in my head, and if I can't, I jot them down on a piece of paper. It's a splendid idea, that. It's helped me lots of times in conversation. I'm as fond of the word microcosm as I am of vocabulary, too, but I never can remember it, so I keep it on a piece of paper in my vest-pocket. Whenever I want to use it, I know just where to find it."

"And what does microcosm mean?" asked Mollie.

"I don't know," said the Unwiseman; "but few people do; and if I use it, not one person in a thousand would dare take me up, so I just sprinkle it around to suit myself."

As the Unwiseman spoke, the postman came to the door with a letter.

"Ah!" said the Unwiseman, opening it and reading it. "I am sorry to say that I must leave you now. I have an engagement with my hatter this afternoon, and if I don't go now he will be much disappointed."

"Is that letter from him?" asked Mollie.

"Oh no," said the Unwiseman, putting on his coat. "It is from myself. I thought about the engagement last night, and fearing that I might forget it I wrote a short note to myself reminding me of it. This is the note. Good-bye."

"Good-bye," said Mollie, and then, as the Unwiseman went off to meet his hatter, she and the others deemed it best to go home.

"But why did he say he expected you to call and then seemed surprised to see you?" asked the new doll.

"Oh—that's his way," said Mollie. "You'll get used to it in time."
