Leonard sprang up unhurt, and together they ran, rather than walked, back to the spot where they had left Soa.
She was watching for them, and pointing to Leonard’s coat, asked “How many?”
“One,” answered Otter.
“I would it had been all,” Soa muttered fiercely, “but you are only two.”
“Quick,” said Leonard, “into the canoe with you. They will be after us presently.”
In another minute they had pushed off and were clear of the island, which was not more than a quarter of a mile long. They paddled across the river, which at this spot ran rapidly and had a width of some eight hundred yards, so as to hide in the shadow of the opposite bank. When they reached it Otter rested on his paddles and gave vent to a suppressed chuckle, which was his nearest approach to laughter.
“Why do you laugh, Black One?” asked Soa.
“Look yonder,” he answered, and he pointed to some specks on the surface of the river which were fast vanishing in the distance. “Yonder go the boats of the slave-dealers, and in them are their arms and food. We cut them loose, the Baas and I. There on the island sleep two-and-twenty men—all save one: there they sleep, and when they wake what will they find? They will find themselves on a little isle in the middle of great waters, into which, even if they could, they will not dare to swim because of the alligators. They can get no food on the island, for they have no guns and ducks do not stop to be caught, but outside the alligators will wait in hundreds to catch them. By-and-by they will grow hungry—they will shout and yell, but none will hear them—then they will become mad, and, falling on each other, they will eat each other and die miserably one by one. Some will take to the water, those will drown or be caught by the alligators, and so it shall go on till they are all dead, every one of them, dead, dead, dead!” and again Otter chuckled.
Leonard did not reprove him; with the talk of these wretches yet echoing in his ears he could feel little pity for the horrible fate which would certainly overtake them.
Hark! a faint sound stole across the quiet waters, a sound which grew into a clamour of fear and rage. The slavers had awakened, they had found the dead man in their midst mysteriously slain by an invisible foe. And now the clamour gathered to a yell, for they had learned that their boats were gone and that they were trapped.
