Charley came crawling up out of the water half dead with terror.

It was some time before Dick recovered himself.

Charley dressed and they stood side by side discussing the situation and watching the lake.

“We are even now, Charley,” said Dick. “We have both broken orders and fired at the Plesiosaurus. I suppose if we are going to keep on seeing the creature we shall get used to him in time, but, upon my word, he’s the strangest looking citizen I ever laid my eyes on, that’s one sure thing.”

“A regular nightmare,” said Charley. “Come, let’s look up Doctor Dan. He must have heard the firing and is no doubt wondering what it means.”

The guide came running up before they were out of the cove.

“So you have been firing at him again!” he exclaimed. “You are bound to kill him it seems.”

“I’m the one this time,” said Dick, and he told the story.

“Well, well! That settles the question!” exclaimed Dr. Dan. “The monster is real—it is very much alive—it is ready any time to make a meal of one of us. We want to look out.”

“I move we make the circuit of the lake,” said Charley.
