“Did you get hurt on your balloon trip?”

“Where did you leave the balloon?”

“We were afraid you were all killed.”

Such were some of the remarks and questions uttered by those who had returned to the Hall after the departure of the balloon with the boys.

“We are safe and sound,” said Jack, speaking for himself and his chums.

“What have you got there?” asked Dale.

“Something for Mr. Strong,” whispered Pepper. “Where is he?”

“In the Hall. Captain Putnam is out hunting for you. He said if you were found, to fire the cannon.”

“All right, then fire it,” said Andy.

The three boys marched into the Hall with their precious burden. They were told that Mr. Strong had gone to his room, and so followed up the stairs and knocked on the door.
