The serpent, having satisfied his rage, withdrew his horrible fangs and took to flight. The colonel felt a damp, icy body touch his cheek; he remained motionless. The serpent glided rapidly along the side of the subterranean passage and escaped.

The danger past, the colonel remained some moments petrified with terror; he heard the last struggle of John; his agony was short. Rutler heard him make several convulsive shudders and that was all. His companion was dead. Then Rutler advanced and seized the sailor's leg. The leg was already cold and stiff; for the venom of the serpent works rapidly.

A new cause for fear assailed the colonel. The serpent, not finding an egress in the cavern, might return the same way it had gone. Rutler seemed already to hear a slight noise behind him. He could not proceed in advance, because the body of the sailor completely blocked the passage; flight by the rear was only to expose himself to an encounter with the serpent. In his terror the colonel seized the corpse by the two legs, to the end that he might drag it to the entrance of the subterranean passage and thus clear the only outlet to the cavern. His efforts were in vain. Whether his strength was paralyzed, he being in such a cramped position, or whether the poison had already distended the body, Rutler could not extricate it.

Not wishing to think that this only and last chance for salvation was taken from him, he found a means of detaching his belt and of fastening it to the feet of the dead man; he took it between his teeth, and, aiding himself by his two hands, pulled with all the energy of despair. He could scarcely cause even the slightest movement of the corpse. His terror increased; he sought his knife, in the mad idea of cutting up the body of the sailor. He saw soon the uselessness of this attempt.

The pistols and ammunition of the colonel were in the sack of skin swung over the shoulders of the dead man. He set himself to work to remove the sack from his companion; he did so after great difficulty. He then set himself anew to retreat to the entrance of the passage.

Once again in the cavern he felt faint, but the air revived him; he plunged his head into the cold water and seated himself on the sand. He had almost forgotten the serpent. A long hiss caused him to raise his head; he saw the reptile balancing itself a few paces above him, half coiled up on the rooks which formed the roof of the cavern.

The colonel recovered his coolness at the sight of this danger; remaining almost immovable, and using his hands only, he unfastened his pouch and drew from it a pistol and cocked it. Happily the charge and priming were intact.

At the moment that the serpent, irritated by the movement of Rutler, precipitated itself upon him, the latter aimed and fired. The serpent fell at his feet with his head crushed. It was of a blue-black, spotted with yellow, and some eight or nine feet in length.

Delivered from this enemy, and encouraged by his success the colonel made a final effort to clear out the only path by which he could pass. He glided anew into the passage, but, in spite of his strength, his efforts were in vain—he could not move the corpse of the sailor.

Returning to the cave, he examined it in every direction but could find no outlet. He could not hope for help outside; his shouts could not be heard. At this terrible thought his eyes fell upon the serpent. Here was a momentary resource; he knew that sometimes the famished negroes ate this flesh, which, though repulsive, was not poisonous.
