"Yes," Valentine said, "time presses."

The two men remained alone for about two hours discussing the hunter's plan, and when all was settled they separated—Valentine to return to the mission, and El Buitre to rejoin his companions, who were concealed a short distance off.


[CHAPTER IV.]

THE EXPLOSION.

During Valentine's absence facts of extreme gravity had occurred at the mission. The Count de Prébois Crancé had finished his correspondence, and held in his hand the letters he had just written, while he gave a peon, already mounted, his final instructions. At this moment the advanced posts uttered the cry of "Who goes there?" which was immediately taken up along the whole line. Louis felt his heart contracted by this shout, to which he was, however, accustomed; a cold perspiration beaded on his temples; a mortal pallor covered his face; and he was forced to lean against a wall lest he should fall, so weak did he feel.

"Good heavens!" he stammered in a low voice, "what can be the matter with me?"

Let who can explain the cause of this strange emotion, this inner presentiment which warned the count of a misfortune; for our part, we confess our inability, and content ourselves with recording the fact.

The count, however, wrestled with this extraordinary emotion, for which there was no plausible reason. Owing to a supreme effort of the will, a perfect reaction took place in him, and he became once more cold, calm, and stoical, ready to sustain, without weakness as without bravado, the blow by which he instinctively felt himself menaced.

In the meanwhile an answer had been returned to the sentries' challenge, and words exchanged. Don Cornelio came up to the count, his face quite discomposed by astonishment, and himself a prey to the most lively emotion.
