They were close to where they usually moored the boat, about fifty feet from where the tent was set up.

“Some one is rattling away among the pots and pans,” remarked Ned. “Maybe it’s some of those negroes who have followed us.”

“Or Seminole Indians,” added Bob.

“More likely some animal,” observed the professor.

“Then it had better leave before I take a shot at it,” exclaimed Bob, getting his gun in readiness.

The boat was approaching closer, and the noise amid the camp stuff could be plainly heard. It sounded as though some animal like a cow was nosing among a lot of tin pails after something to eat. Jerry shut off the power and the boat slowly drifted to the shore.

“Let me get at him!” cried Bob.

“Look out! It may be a manatee!” cautioned Ned with a laugh.
