"It's not," said the bear; "never tell it if it doesn't hurt. Under those circumstances, I say, tell a bear faced lie."

"You haven't a very sweet disposition, have you?"

"No, thank goodness, I haven't—what would a Bug Bear do with a sweet disposition unless he could eat it?"

"I don't know," said Billy.

"Of course you don't—nobody ever said you did—boys don't know anything."

"Here we are," cried the Little Bug Bear. And sure enough, they were standing in the strangest of strange looking towns. Every house and every building was covered with an enormous derby hat, while the windows and doors were so arranged that at a little distance they looked like the eyes and nose and mouth of a face.

"Where are we?" asked Billy, looking about him in surprise.

"Derby Town—where else do you think?" said Big Bug Bear.

"I didn't know," said Billy.
