As the days went on, and the circus traveled from place to place, Tinkle gave many exhibitions of his smartness. He learned new tricks and he could do the old ones much more easily the oftener he practiced them, just as you can with your music lesson.

But though he liked it very much in the circus, Tinkle was sad. His animal friends could tell that by looking at him, and the pony did not eat as well as he had at first.

“Come now, Tinkle, tell me what the matter is,” came a voice behind him one day, and, turning, the pony saw a funny monkey seated in the straw on the ground.

“I am Mappo, the merry chap Tum Tum and Dido told you about,” went on the monkey. “I haven’t had time to come to see you before. I’ve been kept so busy in this circus.”

“Oh, yes, I remember Dido and Tum Tum speaking about you,” said Tinkle. “Thank you for coming to see me.”

“Well, you don’t look very happy over it,” said Mappo. “Come, what is the trouble? Why are you sad? Look at me, I’m merry enough for any one,” and Mappo turned a somersault that made Tinkle laugh in his pony way.

“Come! That’s better,” said Mappo. “Be jolly like Tum Tum. What is the matter, anyhow?”

“Oh, I feel sad when I think of the nice home I was taken from,” said Tinkle. “I miss George and Mabel, and I’d like to be with them again, to let them ride on my back or pull them about in the pony cart. That is why I am sad.”
