"Don't we have to go upstairs and out of doors?" asked Twinkle.

"Oh, no," replied the prairie-dog, "we have halls connecting all the different houses of importance. Just follow me, and you can't get lost."

They might easily have been lost without their guide, the little girl thought, after they had gone through several winding passages. They turned this way and that, in quite a bewildering manner, and there were so many underground tunnels going in every direction that it was a wonder Mrs. Puff-Pudgy knew which way to go.

"You ought to have sign-posts," said Chubbins, who had once been in a city.

Last week a gray owl stopped with us for a couple of days, and we had a fine ball in her honor. But you are the first humans that have ever been entertained in our town, so it's quite an event with us." A few minutes later she said: "Here we are, at the Mayor's house," and as they passed under a broad archway she blew out her candle, because the Mayor's house was so brilliantly lighted.
