"That's the electrical apparatus smashing through the floor!" called Tom. "Come, let's get out of here before the gasolene sets anything on fire. Are you all right, Mr. Damon, and you, Mr. Fenwick?"
"Yes, I guess so," answered the inventor. "Oh, what a terrible crash! My airship is ruined!"
"You may be glad we are alive," said Mr. Damon. "Bless my top knot, I feel"
He did not finish the sentence. At that moment a piece of wood, broken from the ceiling, where it had hung by a strip of canvas came crashing down, and hit Mr. Damon on the head.
The eccentric man toppled over on his pile of cushions, from which he was arising when he was struck.
"Oh, is he killed?" gasped Mr. Fenwick.
"I hope not!" cried Tom. "We must get him out of here, at all events. There may be a fire."
They both sprang to Mr. Damon's aid, and succeeded in lifting him out. There was no difficulty in emerging from the airship as there were big, broken gaps, on all sides of what was left of the cabin. Once in the outer air Mr. Damon revived, and opened his eyes.
