"But, I say, what have they gone after ?" "To try and find us." "But they don't know us." "Well, the people who are using this cave, and they must know of the way up to the top.

Ah! that's it." "Yes; what ?" cried Mike excitedly.
"Hist! don't speak so loudly.

They've gone up there to loosen some of the stones and block the way, so as to put an end to any one coming down; or else to lay wait and trap us." Mike drew a long, deep breath; and it sounded like a groan.
"Oh dear!" he said; "whatever shall we do?
Perhaps we had better get through into the other cavern.

They'll search this thoroughly, perhaps, when they come back; but they mayn't search that." "That's what I thought," said Vince.

"Yes, it's the only thing for us to do, unless we go into the seals' cave and try and hide there." "Ugh!" said Mike, with a shudder.
