"And that is my belief yet; but I have no means of knowing surely."
"I hope she bumps the world again!" cried Jack. "Maybe we can get off then."
"It will do a lot of damage when it falls," said Andy Sudds, reflectively. "Some folks up there in the earth will get hurt."

"Not if we came down into one of the big oceans," said Professor Henderson. "We would probably sink some vessels, and might overwhelm islands; but if this island in the air is as big as Australia it could easily fall into the Pacific and do no particular harm to any present existing body of land—save through the great tidal waves that would result from such a fall."
"It is an awful thing to think of," cried Mark. "I don't see, no matter how this awful affair ends, but that we are bound to be overwhelmed."
"We do not know that," declared the professor, with his wonted cheerfulness. "Never say die. Our safety is in the hands of Providence. We have not got to worry about that."
