"I think it will fill us with chills and fever," said Fred. "Ugh, how damp it is, now the sun is going down."

"There is a mist creeping up," said Harold Bird. "Too bad! I was in hope it would remain clear."

"It can't be helped," said the owner of the launch. "We'll have to wait until daylight. If I light the acetylene gas lamp it will simply put those rascals on guard."

"Vot is ve going to do—sthay on der poat all night?" asked Hans.

"We can either do that or go ashore—just as you wish."

"Let us move towards shore," said Dick. "It will be more pleasant under some overhanging trees or bushes."

This was agreed to, and they steered for the bank of the lake, which was not far away. None of them dreamed of what that night was to bring forth.
