In the meanwhile, Mr. Damon and Mr. Fenwick had been investigating the contents of the storeroom. There was a large supply of food, much larger than would have been needed, even on a two weeks' trip in the air, and the inventor of the Whizzer hardly knew why he had put so much aboard.
"But if we have to stay here long, it may come in handy," observed Tom, with a grim smile.
"Why; do you think we will be here long?" asked Mr. Damon.
The young inventor shrugged his shoulders.
"There is no telling," he said. "If a passing steamer happens to see us, we may be taken off to-day or to-morrow. If not we may be here a week, or" Tom did not finish. He stood in a listening attitude.
There was a rumbling sound, and the earth seemed again to tremble. Then there came a great splash in the water at the foot of a tall, rugged cliff about a quarter of a mile away. A great piece of the precipice had fallen into the ocean.
"I thought that was another earthquake coming," said Mr. Damon, with an air of relief.
"So did I," admitted Mr. Fenwick.
"It was probably loosened by the shock, and so fell into the sea," spoke Tom.
