"The water is too cold," objected Cale.

"I don't care."

Tad quickly stripped off his clothes, and Ned decided that he, too, needed a swim, so he undressed. The two lads plunged into the little lake, and Ned uttered a yell when his body came in contact with the almost ice-cold water.

"Swim hard and you will not notice it," chattered Tad.

"I s-s-s-see you don't," answered Ned.

"Race me for the other side. Now, go!" cried Tad.

The boys struck out in swift, powerful strokes. Cale Vaughn's eyes sparkled as he observed the swimmers.

"I would give a great deal if I could swim like that," he mused.

"Oh, that's nothing. I can beat that swimming with my feet tied," answered Stacy. "I'm a natural-born swimmer."

"I should say you were a natural everything, according to your idea of yourself," grinned the guide.
