"I fear so," agreed Mr. Roumann. Then he asked: "Where have you been hiding?"
"Ah, I fooled you, all right," said the man with a cunning laugh. "It was just like a game of hide and seek to watch you hunting for me, and me looking at you all the while. Ha, ha! Oh, I had a good place."
"Where was it?" asked Mr. Roumann soothingly.
"Right up there," answered the machinist, pointing to the roof of the storeroom. The German made an investigation, and discovered a small compartment where it had been intended to make a port, but the idea for which had not been carried out. This left a space in the wall of the projectile, large enough for a man to conceal himself in. No one would suspect he was there.
"I sneaked on board one night," went on the man. "I managed to open a port into the storeroom. And I lived high, I can tell you."
"Golly! He's been at mah kitchen stuff!" exclaimed Washington.
"Did that other man come aboard with you?" asked Jack. He referred to the tramp who had peered in the window of the professor's house.
"No. He's been elected King of France," was the answer. "He had to go over there to get his crown fitted on. I'm all alone here. A few minutes more and I would have smashed that engine."
"I guess you would," responded Mr. Roumann. "Well, we'll take good care that you do not get loose again."
The bonds of the maniac were made more secure, and Washington White was told to keep, close watch over him.
