"There goes the Swastika."

A sharp whistle announced the departure of the larger boat. Presently there came floating over the water, over the key, the quaint, plaintive sound of untrained voices enthusiastically raised in song. Roger smiled grimly as he pressed his ear to the crack and caught the faint words:

"Shall we gather at the river?
The beautiful, the beautiful river——"

Granger's voice was distinguished above the rest; he was on the job; he was leading his shorn flock back from the gates of Paradise to the tune of a hymn. At Flora City, Granger, being through with this flock, would quit it; and ere its members, obstructed time after time in their efforts to reach the Colony, would disperse, Granger, in a new field, would be laying his snares for fresh victims.

In a few minutes the hull of the Cormorant began to throb with the drive of her powerful engines. With no word of command she slid silently away from her mooring to the deep channel and began to drive her way upstream at a speed that caused Roger and Higgins to look at one another. The captain was in the wheelhouse above their heads, the mulatto lounged on the deck near the cabin door; so they did not even dare to whisper, but each knew the question the other would ask: Why such terrific speed in a dirty craft like the Cormorant?

Through his precarious peekhole Payne caught glimpses of the water and land that the Cormorant was leaving behind her. At first there was little to see save blue water, for the mouth of the Chokohatchee was more an estuary of the sea than a river. Far away on either side were the low-growing tangled growths of mangrove which represented the river's banks near the sea, and toward these banks, from both sides of the wake, water birds could be seen winging their way, frightened from their feeding ground by the Cormorant's rush. Great, clumsy pelicans rose painfully and flew with surprising speed, once they were in the air; small blue herons went shoreward in uncountable flocks, flying high into the morning sun. Close to the water, ducks of many kinds clove the air with business-like intent and speed.

The water itself seemed alive with an abundance of life. The black back of a porpoise showed above the surface; far away the sun glinted on the silver scales of a leaping tarpon. The red sides of a mangrove snapper were seen as it tried in vain to escape the jaws of a steel-gray barracuda, and a moment later half of the slim barracuda flew into the air as the jaws of a shark, catching it in full flight, snapped it in two.

The course of the Cormorant was shifted slightly, and by the muddy color of the water Payne knew they were entering the river proper. The stream here was perhaps two hundred yards across and over the stern, to port and starboard, the banks were plainly visible. The land was low, so low that it seemed but a little higher than the water level, but it bore an amazingly abundant growth. The river seemed to flow through a channel cut in the dense, solid vegetation. Great cypress trees towered up from the water, enormously thick at the roots and rapidly dwindling above. Between their rough trunks cypress scrub, sturdy cabbage palms, mangrove, custard apple and other varieties of tropical trees found space to grow; and between the trunks of the smaller trees was a tangle of palmetto, saw grass, jungle vine, Virginia creeper and the beautiful moon vine and its dainty flowers. Blue, yellow and red flowers peeped from the tangle. Air plants bearing in their hearts scarlet orchids clung to the trunks of hoary live oak, and the Spanish moss, fragile, listless, drooping, hung like delicate drapery over all.

The stream grew narrower and the turtles upon the shore became visible. A water turkey, though the boat was past, fell clumsily off its perch into the water and after frantic efforts flopped away. Alligators lay here and there along the banks; and a wild hog plowed about in the matted water-hyacinths, unconcernedly seeking food, not alarmed by the alligators or the boat or by the fierce brown Mexican buzzards—the killing variety—which contemplated him from the dead cypress branches above.
