“Well, I’ll think it over,” said Dick. “Come on now and let’s have a look at the boiling pot.”

This was the name the boys had given to the point on the lake which so interested Charley and they now went back into the boat and paddled along the shore until they came to the place.

The water was now as calm here as elsewhere and showed no signs of disturbance.

After pulling around a few moments Dick paddled ashore, declaring that he was going to look up the footprints of the monster and measure them.

“You don’t need any help, I suppose,” said Charley. “I’ll stay out here. I want to watch the pot.”

“They say a watched pot never boils,” laughed Dick, “but I’ve no objections to you trying to prove it. Of course I don’t need any help. It won’t take me five minutes, anyhow.”

So Dick hurried along the shore, while Charley paddled out on the lake again. There was no difficulty in finding the impress of the monster’s huge feet in the sand and Dick got out his rule and was in the act of measuring them when all at once a shout from Charley called his attention to the lake.

“She boils, Dick! She boils!” cried Charley.

“Look out!” shouted Dick, running down to the shore. “Don’t go too near. There may be some suction there.”

“By Jove, there is a big suction,” answered Charley, “and what’s more I’m right in it now.”
