"Do you think they'll perform with me?" Joe wanted to know.

"They'll have to!" exclaimed the ring-master with energy. "This is my circus, not theirs. They'll do as I say, and if there is any funny business—— Well, there just won't be," he added significantly.

"Do Tonzo and Sid want Sim to come back and act with them?" asked Joe, as he deposited his valise in a corner of a dressing room that was made by canvas curtains partitioning off a part of a large tent.

"That's what they say. Tonzo told me that Sim would behave himself. But I'm through with Sim, and he might as well understand that first as last. You're going to take his place. Now I'll have to leave you. You'll put up at the hotel with some of the performers. Here's your slip that you can show to the clerk. I'll see you in the morning, if not before, and make arrangements for your act. To-night you just look on. Now I've got to go."

Joe looked about the dressing room. It was evidently shared with others, for there were suits of men's tights scattered around, as well as other belongings. Joe left his valise and went outside. He wanted to see all he could—to get familiar with the life of a circus.

It cannot be said that Joe was exactly easy in his mind. He would much rather have joined the circus without having supplanted a performer of so vindictive a character as Sim Dobley. But, as it had to be, the lad decided to make the best of it.

"I'll be on the watch for trouble," he murmured as he went out of the dressing tent.

A busy scene was being enacted on the circus lots. In fact, many scenes. It was feeding time for some of the animals and for most of the performers and helpers. The latter would dine in one of the big tents, under which long tables were already set. And from the distance Joe could catch an odor of the cooking.

"My, but that smells good!" he told himself. He was hungry.

The Sampson Brothers' Show was a fair-sized one. It used a number of railroad cars to transport the wagons, cages and performers from place to place. On the road, of course, the performers and helpers slept in the circus sleeping cars. But when the show remained more than one night in a place some of the performers were occasionally allowed to sleep at the local hotels, getting their meals on the circus grounds, for the cooking for and feeding of a big show is down to an exact science.
