“Poor Tubby! Poor Tubby!” was all Wyn could say. “Let’s paddle around to the boys’ camp. He’s run for home.”

“It was a home run, all right!” gasped Frank.

But three minutes later, when the canoes got into the cove where Polly’s father had met with his accident in the Bright Eyes, Wyn suddenly found something more serious than Tubby Blaisdell’s experience to worry about. There was the big bateau, its sail furled, almost over the spot where Wyn and Polly were sure the lost motor boat lay!

“Oh, dear me!” cried Bess. “Now we can’t have any fun on the raft. Those men will be in our way. What do you suppose they are poking around there in the water with those poles for?”

Wyn began to paddle fast. She shot ahead of the other girls and aimed directly for the bit of beach on which the boys’ canoes were drawn.

The noise and laughter up at the camp assured her that Tubby had arrived and that all the Busters were at home. Wyn had made up her mind quickly that, if she must, she would rather take the boys into her confidence about the sunken boat than let those bateau men find it.

“Boys! Dave!” she hailed them from the water.

Young Shepard appeared at once and, seeing Wyn, ran down to the shore.

“Will you help us?” gasped Wyn. “Quick! get the boys! Move your diving float where I tell you; those men will find it first, if you don’t.”

“Find what?” demanded Dave. “Are you sensible, Wynnie?”
