now I can stop the wagon, if they will only take this chain off my
leg, so I can get out there," thought Tum Tum, as he pulled and tugged
at the chain and peg.

Outside the tent men were running and shouting. Some of them tried to
put stones in the way of the wagon wheels, but the tiger's cage was so
heavy that it rolled right over the stones.

The tiger was frightened and angry, and he growled and snarled, until
you would have thought he was back in the jungle again.

"Let me loose! Let me loose!" trumpeted Tum Tum through his trunk, as he
waved it to and fro. Of course none of the circus men could understand
this language, but Tum Tum's keeper knew what the big elephant meant.

The keeper came running in the tent.

"Tum Tum!" he cried. "I believe you can stop that wagon. Stop the tiger
cage! Get in front of it, and push on it with your big head. That will
stop it from rolling down hill!"

"I will! I will!" said Tum Tum, only, of course, he spoke in elephant
language.

The keeper soon took the chain off Tum Tum's leg, and the big elephant

he knew monkeys are very much afraid of tigers. "I won't let him get
you, Mappo," said Tum Tum.

On rushed the big elephant toward the rolling cage. He got in front of
it, and then he stood still, in the middle of the hill, waiting for the
tiger's cage, on wheels, to roll down to him.

"Look out, Tum Tum, or it will hit you!" chattered Mappo.

"That's what I want it to do," said Tum Tum. "But it can't hurt me, as
my head is so big and strong. Now you watch me!"

On came the tiger's cage. Tum Tum stood there ready to let it bunk into
him. His legs were spread far apart so he himself would not be knocked
over.

Bang!

That was the tiger's cage hitting Tum Tum on the head.

"Ouch!" yelled the big elephant through his trunk, for though it did not
hurt him much, he felt a little pain.

Then he stood there, and pushed so h
