It was another bottle. The bottom of this one had been cut off, and, after the guinea pig had been put inside, the bottom was cemented on again. This was done just before the trick was performed. On his way back to the stage, after having given the lady the glass of water, Joe substituted the bottle containing the guinea pig for the empty one that had held the three liquids. This was where his quick sleight-of-hand work came in. When he gently broke the bottle it was easy enough to remove the little animal, which had been used in tricks so often that it was used to them.

Joe brought the show to a satisfactory conclusion, perhaps a little earlier than usual, as he was anxious to get to the hotel and see how the professor was. The audience seemed highly pleased with the illusions the boy wizard gave them, and clapped long and loud as Joe made his final bow.

He left the theatrical people and his helpers to pack up, ready for the trip to the next town, and hastened to the hotel. There he found Professor Rosello much better, though still suffering somewhat.

"Do you think you will be able to go on to-morrow night?" asked Joe.

"I don't know," was the answer. "I can tell better to-morrow."

But when the next day came, after a night journey that was painful for Mr. Crabb, he found that he could not give his portion of the performance.

And as Joe alone was not quite qualified to give a whole evening's entertainment it was decided to cancel the engagement. It was not an important one, though several good "dates" awaited them in other towns on the route.

"I think I need a rest, Joe," the professor said "My nerves are more shattered than I thought by that electrical accident. I need a good rest to straighten them out. I think we'll not give any performances for at least a month—that is I sha'n't."

Joe looked a little disappointed on hearing this. His living depended on working for the professor.

"I say I'll not give any more performances right away, Joe," went on the professor, "but there's no reason why you shouldn't. I have been watching you of late, and I think you are very well qualified to go on with the show alone. You could get a helper, of course. But you can do most of my tricks, as well as your own. What do you say? I'll make you a liberal offer as regards money. You can consider the show yours while I'm taking a rest. Would you like it?"
