"Hark! Did you hear that?"

"What?" asked Freddie.

"A noise, like something growling!"

Freddie looked back over his shoulder into the dark part of the cave. Then, speaking as boldly as possible, he answered:

"I didn't hear it. Anyhow, I guess it was the wind. Come on, we'll go home!"

"Are we going back in the boat?" Flossie asked.

"I guess not," Freddie replied. "It'll be rough out on the lake—it always is after a storm. We can walk down the path to our camp. Besides, this isn't our boat. Maybe it belongs here and we'd better leave it."

"Then you'd better tie it," said Flossie. She and her brother had been told something of the care of boats, and one rule their father had given them was always to tie a boat when they got out of it. In the excitement of the storm the children had forgotten this at first, but now Flossie remembered it.

"Yes, I'll tie the boat," Freddie said, "and then whoever owns it can come and get it."

It did not take him long to scramble around to the edge of the little cove. Once there, he tied the rope of the boat fast to a large stone that was half buried in the ground. Making sure it would not slip off, Freddie came back to where Flossie waited for him.
