But on a closer examination, in that bright river were to be seen myriads of hideous, greedy alligators. The luxurious trees afforded refuge for legions of troublesome insects, and noxious reptiles; in the flowering under-growth lurked deadly and venomous serpents; and most of the gay creeping plants were poisonous; the fairy-looking schooner was discovered to be a sink of moral infamy: the small boats were ladened with miserable captives; and even the partly seen Factory was a den of sin and suffering.

The natural and the artificial harmonized well—both charming, lovely, enticing, but equally corrupt, dangerous, and unwholesome.

In eight days the slaver’s living freight was all received on board. The day before, Willis had dispatched Mateo in a small boat to the mouth of the river, for the purpose of seeing if the coast was clear, and that no men-of-war were in sight; for nearly all the slavers that are captured, are caught just as they make out from the rivers, and before they have sea-room enough to enable them to use to advantage their superior sailing qualities.

The mate, on his return, reporting all safe, the schooner got under weigh, and after working down the river, put to sea with a fair wind, and every inch of canvas set that would draw, and steered for the Isle of Cuba—her cargo all being engaged to a negro trader at the eastern end of the island.

The external appearance of the Maraposa was unaltered, still as beautiful and attractive as when we saw her lying at anchor near Havana. But inboard, a great change had taken place; then, the tidy look of every thing, the quiet and careless expression visible on the countenances of her unarmed crew, gave rise to thoughts of peace and tranquillity; even the bright brass cannon seemed more for ornament than for dealing deathly execution. But now, every sailor had thrust in a belt encircling his waist, a brace of heavy pistols; keen cutlasses were ranged in racks around the masts, ready to be grasped in an instant; the long gun was pointed toward the tafferel, her gaping muzzle ready to be trained on either gangway; in the hold, seen through the main-hatchway, was a black, compact mass of human beings, crowded as close together as it was possible to get them, the light striking upon their constantly rolling eyes, made them appear spots of moving fire; groans, awful and horrible, the sounds of retching, and the incessant clanking of fetters, smote upon the ear. An odor the most nauseating and disgusting, (caused by the confinement of so many in a space so small,) filled the air, and would have overpowered the nerves of any but those accustomed to it; but upon the hardened crew, it had no more effect than upon the schooner, who, rushing through the water with the rapidity of a dolphin, sped on toward her port.
