The captain's anxiety was extreme; he dared not make the slightest movement through fear of being surprised, and yet the canoe was still there. Desirous, however, of knowing how matters really stood, Leon softly drew his knife from his boot, and, holding his breath, crouched down in the river, only leaving his face above water.
All at once he gave a start; he had seen flashing in the dark, like two live coals, the eyes of a savage, who, swimming behind the canoe, was pushing it forward with his arm. The Indian held his head above water, and was looking about him inquiringly.
Suddenly Leon, on whom the eyes had first been fixed, leaped forward with the activity of a panther, seized the Indian by the throat, and before he was able to defend himself or utter a cry of alarm, plunged his knife into his heart.
The Indian's face became black; his eyes were enormously dilated; he beat the water with his legs and arms, then his limbs stiffened and he sank, carried away by the current, and leaving behind him a slight reddish track. He was dead.
Leon, without the loss of a moment, got into the canoe, and holding by the reeds, looked in the direction where he had left his comrades. Both had followed him, bringing with them the rifle which Leon had laid on the ground, and which they were careful to keep above water, as well as their own.
Then the three men, making as little noise as possible, disengaged the canoe from the reeds which had barred its progress, and lay down in the bottom, after placing it in mid-stream, and making it feel the current. They went on thus for some time, believing themselves already safe from the invisible enemies who surrounded them, when all at once a terrible clamour broke out, and awoke the echoes.
The body of the Indian killed by Leon had followed for some minutes the course of the river, then had become entangled in the reeds, and eventually stopped exactly in the centre of the Indian camp, in whose proximity Leon and his comrades halted that night without suspecting it.
At the sight of their brother's corpse, the redskins had uttered the formidable yell which the smugglers heard, and rushed tumultuously to the bank, pointing to the canoe. Leon seized the paddles, which were in the boat, and, aided by Wilhelm, was soon out of reach.
