"Aren't there crocodiles, too, in Florida?" asked Sumner.

"Yes. Professor Hornaday mentions genuine crocodiles as being found in Biscayne Bay, on the east coast, where I hope we shall get a look at them. They are described as differing from alligators in the head, that of the crocodile being narrower and longer. The snout is sharper than that of an alligator, and at the end of the lower jaw are two long canine teeth or tusks that project through holes in the upper lip."

"Him big fighter, too," remarked Quorum from the cruiser. "Him heap mo' wicked dan de 'gator. De Injun call him 'Allapatta hajo,' an' say hit mean mad 'gator."

As the party advanced up the stream the current became so much stronger that the boys began to feel the effects of their steady paddling against it, and were no longer inclined to shoot ahead of the others. The foliage of the banks changed with each mile, and by noon the pines had given place to clumps of palmetto, bay, water-oak, wild fig, mastic, and other timber. Here and there were grassy glades, in more than one of which they caught tantalizing glimpses of vanishing white-tailed deer.

The water began to assume an amber tint, and was so brilliantly clear that in looking down through it they could see great masses of coral rocks that often overshadowed the yawning mouths of dark chasms. Above these, whole meadows of the most beautiful grasses—red, green, purple, and yellow—streamed and waved with the ceaseless motion of the current. Schools of bright-hued fish darted through and over these, and turtles, plumping into the water from stranded logs or sunny sand-spits, could be seen scuttling away to their hiding-places among them.

The noontide heat of the sun was intense as the signal for a halt was given. The boats were turned in towards a bank where a grass-plot, shaded by a clump of rustling palmettoes, offered a tempting resting-place.

As they landed, Worth was certain that he saw a flock of turkeys disappear in a small hammock back of the clearing. With his new-born hunting instinct strong within him, he seized his gun and crossed the glade, in the hope of getting a shot. He had practised constantly on the call given him by his instructor, and now felt competent to deceive even the most experienced gobbler. Advancing cautiously within cover of the hammock, and seating himself on a log that was completely concealed by a screen of bushes, he began to call, "Keouk, keouk, keouk." For ten minutes or so he repeated the sounds at short intervals without getting a reply. Suddenly, a slight rustle in the bushes behind him caused Worth to turn his head. Within a yard of him glared a pair of cruel green eyes.

With a yell of terror the boy dropped his gun, sprang to his feet, burst from the bushes, and fled wildly towards camp. Reaching it in safety, but hatless and breathless, he declared that a tiger had been crouched, and just about to spring at him.

"Perhaps it was a 'coon," suggested Sumner.

"'Coon, indeed?" cried Worth, hotly. "If you had seen the size of its eyes, you would have thought it was an elephant!"
