"Oh, Jack! are you going to let them take possession?" questioned Fred, in a low voice.

"What do you fellows think we ought to do?" queried the oldest Rover boy quickly.

"I think we ought to make them keep out until Uncle Barney gets back," answered Randy.

"That's my idea, too," added his twin.

"They may have the right to this island, but I'd make them fight it out with Mr. Stevenson," was Fred's comment.

"That's just the way I look at it, too," answered Jack. "Come on, Randy; we'll guard that cabin while Andy and Fred can remain here to guard this place."

"Would you dare to shoot at them?" questioned Fred anxiously.

"I don't think there will be any necessity for shooting, Fred. I think if we merely show we mean business they will keep their distance."

The boys exchanged a few more words, and then Jack and Randy set off on a run for the cabin occupied by Uncle Barney. They outdistanced the visitors, and soon placed themselves in the doorway.

"Now, you keep back!" cried Jack warningly. "Don't come near this place until Mr. Stevenson returns!"
