"I would rather not say, Mr. Sparling," answered the Circus Boy, looking his employer squarely in the eye.

"It is your duty to tell me."

"Not unless I am sure. It would be unjust to do so, and I know you would not wish to force me to be unjust."

"You are a queer boy, Phil Forrest," said the showman, gazing at the lad intently.

"I wish I knew who I thought they were, if they had anything to do with my aerial flight last night," growled Teddy. "They would have reason to think a Kansas cyclone had struck them."

No one paid any attention to Teddy's remark.

"I will tell you what I think, however, Mr. Sparling," continued Phil.

"That's what I am trying to get you to do."

"I think some person with evil intent did something to Jupiter to anger him, thus causing him to turn on Teddy. And it is my opinion that if you will examine the animal you will find the evidences on the animal himself," declared the Circus Boy boldly.

Mr. Sparling uttered an angry exclamation.
