“Oh! you told us before,” cried Lettie. “And, do you know, I told father and he said Sheriff Kimball ought to know about that.”

“About what?” queried Mildred.

“Not that poor dummy?” cried Billy. “There isn’t an ounce of harm in that fellow, I am sure.”

“No. About there being something buried on the island. I don’t know just what father meant. But you know, he is very friendly with the sheriff.”

“Say! we don’t want to get that poor chap into trouble,” Billy urged. “Just like a girl—telling everything she knows!”

Before Miss Parker could “flare up” at this statement and speak her mind, Mildred gave a little shriek.

“What’s the matter?” demanded Dan, flashing a look around, too.

“See him? There!”

“It’s Dummy!” yelled Billy, who was out on the crossbeam at his usual station and could see behind the bellowing sail.

There, upon a high rock on the shore of the island stood the figure of the boy Billy and Dan had knocked over in the snowstorm, weeks before. They could not be mistaken.
