The girls stared blankly at each other and then as the boys laughed, Miss Susie said, "What's the joke?"

"No joke," said Fred. "It's just a fact."

The attention of the party, however, was speedily attracted by the sight of a little boat that was approaching, flying a white flag at the stern.

"Oh, I know what that is," said Miss Susie confidently. "That means that somebody is sick on board and that they are signaling us to help them."

"Huh!" grunted Mr. Button.

"That's not it," responded George.

"Well, what is it then?" demanded the girl.

"It means that somebody on board has caught a muscallonge and they are bringing it in. If any boat catches one it usually puts straight for home and it isn't backward in letting the world know what has happened."

"Have they got the fish with them?"

"Why don't you ask them?" laughed George, handing the girl a megaphone as he spoke.
