"No, that is part of the circus work," answered Leo. "The elephants are so big and strong that they are used instead of horses, sometimes, to push the circus cages."
"But why is Tum Tum helping push the circus cages?" asked Nero. "Has anything happened?"
"Well, something is going to happen," said Leo. "The circus is going to start out on the road—we are going to travel from town to town. We are going to travel on the railroad and live in a tent instead of this barn. We shall see lots of people—boys and girls—who come to watch us eat, and do tricks, and we shall hear the band music and—Oh, it's real jolly!"
"I'm glad of that," said Nero. "I like to be jolly. But will Tum Tum come back?" he asked, for he liked the big, jolly elephant, as, indeed, all the circus animals did.

In a way Nero had learned something of man-talk, too, for he knew what certain words meant.
The trainer would call:
"Jump over the stick, Nero!"
The lion knew what that meant, and he knew it was different from the words used when the trainer said:
