else?" asked Don. "That's a good trick. Let me see you do
another."

"Look!" cried Tum Tum, and this time he stood on his front legs, and
raised his hind ones in the air.

"That's harder to do," said the jolly elephant.

"I should think so," agreed Don. "I'm going to try it myself." Don did
try, but when he wanted to stand on his front legs, he fell over and
bumped his nose. And when he tried to stand on his hind legs, he fell
over backward and bumped his head.

"I--I guess I can't do it," he said to Tum Tum.

"It needs much practice to do it well," spoke the jolly elephant.

"Here, Tum Tum!" called one of the circus men. "This is no time to be
doing tricks. Come and help push some more of these wagons. If the
circus is ever to start out on the road, to give shows in the tent, we
must start soon. Come, push some of these wagons, with your big, strong
head."

"I'll have to go now," said Tum Tum to Don, the dog, for they were now
good friends. "I may see you again, sometime."

"I hope you will," spoke Don. "Your circus is coming to our town, I
know, for the barns on our farm are pasted over with posters, and
bills."

"Then I may see you when we get there," said Tum Tum, as he walked
slowly forward to push the wagon pointed out by the circus man.

That is how Don and Tum Tum became acquainted. As the dog went off with
his master and the boy, he barked a good-by to Tum Tum, saying:

"If you come near our place, I'll show you Squinty, the comical pig. One
eye is wide open, and the other partly shut."

"He must be a funny chap," said Tum Tum. The big, jolly elephant pushed
into place the heavy wagon. Then it was dinner time. But as Tum Tum was
eating his hay and carrots in the animal tent, for he was kept in that,
now that the weather was warmer, all at once Tum Tum heard a loud
shouting.

"Look out for that wagon. The tiger cage wagon is rolling down hill. It
will turn over, be smashed, and the tiger will get out! Stop that
wagon, somebody!"

Tum Tum heard this shouting, and looking out of the side of his tent, he
saw a big red and gold wagon rushing down the hill backwards.

"I must stop that wagon," said Tum Tum.

CHAPTER VII

TUM TUM LOOKS FOR MAPPO

Tum Tum, the jolly elephant, pulled hard on the chain that held his big
leg fast to a stake driven into the ground. He wanted to get loose so he
could stop the wagon from rolling down hill, maybe upsetting and letting
the big tiger out.

"I k
