"Take a look for yourself, Jack," he said; and there was a slight smile on his face while speaking, that told of a discovery of some sort.

"Yes, Jimmy hit the bull's-eye that time," he remarked.

"Then it is smoke?" queried Frank.

"Not only that, but I can make out what seem to be a number of small objects that must be vessels of some sort," Jack went on to say.

"The disappearing fleet!" gasped Jimmy.
