Frank, "and those are sailors who are
singing. We are not alone in the Everglades."
"They're all drunk," declared the professor. "You can tell that by the
sound of their voices. Drunken men are dangerous."
"They're a blamed soight betther than none, fer it's loikely they know
th' way out av this blissed swamp," said Barney.
"They may bub-bub-be pup-pup-pup-pirates!" chattered the professor.
"What sticks me," said Frank, "is how a party of sailors ever made their

The singing ceased after a time, but they were still guided by the sound

"They are quarreling!" exclaimed Frank, softly.
"This is tut-tut-terrible!" stuttered the professor.
Suddenly the sound of a pistol shot came over the rushes, followed by a
feminine shriek of pain or terror!
CHAPTER XXX.
FRANK'S SHOT.
Frank and his two companions were profoundly astonished. As soon as he
could recover, Frank asked:
"Did you hear that?"
"Av course we hearrud it!" returned Barney, excitedly.
"It sounded very much like the voice of a woman or girl," said Professor
