“Why, you didn’t say anything about a big bom boom being there before,” cried Bob. “I don’t believe there is such a thing.”

“Now, how you do go on!” cried Bigley. “You know what I mean—a big bang when the powder went off.”

“Then why don’t you call things by their right name?” said Bob. “A bang’s a bang and nothing else.”

“Well, the powder went bang and knocked the big rock right off the place where it stood.”

“What! Up in the air?” I said.

“Up in the air? No; over into the deep water, where it sank to the bottom.”

“Well, you don’t suppose we’re such old stupids as to think it floated, do you?” cried Bob.

“No, of course not, but that’s what it did.”

“I don’t believe it,” said Bob stubbornly.

“You don’t believe it?” I said, while poor Bigley stood staring at the last speaker.
