"And the best of it is that we haven't seen a bogus ticket!" said the treasurer, much elated.

Joe, as one of the chief owners of the circus, was able to hire the "fire-eaters" unknown to any of his associates until the last minute, and thus the surprise was all the greater.

Joe's fire tricks were now the talk of the theatrical and circus worlds, and he received many offers to leave Sampson Brothers' Show and star by himself. But he refused them all, saying he wanted to build up his own show to a point never before reached.

As he had said, Ham Logan proved a valuable helper. The man, a fire-eater of the old school, knew many valuable secrets, and he held himself under such obligation to Joe that he revealed many of them to the young magician.

"Have you learned anything more about who left that bottle of powerful acid in among my things?" asked Joe of Ham, one afternoon when the fire banquet had been unusually successful.

"No, not exactly," was the answer. "But I'm on the trail, I think I am working along the right lines, but it is too early to make any statement."

"Well, take your time," said Joe. "Only I don't want to get mixed up with any of the deadly stuff."

"Don't worry. I'm on the watch," declared the old performer.

That night, when the time for Joe to prepare for his acts, including the fire tricks, came, he did not see Ham in the dressing tent, where the assistant was usually to be found.

"Have you seen him?" asked Joe of Harry Loper.
