Tyro, affecting the sleepy pace of his companions, patted gently the horse which he held firmly by the bridle; and, without exciting any suspicion, drew nearer to the body of the troop.

His design was to reach the two ladies, and to slip the book in their hands, without being perceived, but he soon saw that this project was impracticable. The two ladies formed the centre of a group.

Tyro, however, was not discouraged.

There was not a moment to be lost. Any hesitation would have been perilous. The day began to advance.

The decision of the Guarani was immediately taken.

Placed at about ten paces behind the two ladies, regardless of what might happen to him, and determined at all hazards to accomplish his mission, he took advantage of a moment when the horsemen to the right and left of the prisoners had removed to some little distance; and giving his horse the rein, he darted off at full gallop.

We have seen that, he succeeded in throwing the book to the marchioness.

Don Pablo Pincheyra, astonished at the unexpected appearance of this horseman, whom he had only seen as he passed, but who appeared to hint not to be part of his troop, prepared to follow him, to find out who he was, when suddenly another care came to change the current of his ideas, by constraining him to look after the safety of his companions. The tempest which had so long threatened them at last burst with extreme violence.

At the first breeze of the hurricane, Tyro understood that a danger, a hundred times more terrible than that from which he had just escaped, hung over his head. Exciting his horse, whose efforts were already prodigious; leaping ravines and bogs, at the risk of dashing himself to the bottom of precipices which he passed in his mad flight, he appeared to fly over this narrow and scarcely practicable path, and which the darkness, which suddenly spread over the mountains, rendered more perilous still.

Suddenly a terrible noise burst at a few paces from him, a cloud of dust enveloped him, his horse started and reared up on his hind legs balancing itself for some minutes on the very edge of the gulf. The Indian thought he was lost. By a prodigy of horsemanship, he gave him the bridle, plunged his spurs into the palpitating sides of the horse, and leant all his weight on the neck of the animal. The horse hesitated an instant, suddenly he bounded forward, and made a few stumbling steps. Then his four legs gave way, he fell, and threw the Indian over his head.
