"In that case, sir, it is impossible; your duty calls you, Don Pedro, to Valdivia, and you would not have time to carry out the expedition which I hope to bring to a successful result. You," the young man continued, addressing General Soto-Mayor, "although your heart may bleed at it, must give up all thought of accompanying me, for ere we had reached the spot where I believe the Señoras to be, fatigue would exhaust your strength, and you would find it impossible to follow me."

"But, sir—" the colonel remarked.

"Pray do not insist, sir," said Leon; "for once again I repeat that, if you wish me to succeed, you must let me act as I think proper."

"What do you propose doing, Leon, that you are afraid of letting us be witnesses of it?" Don Pedro observed haughtily.

"The same as I did when the Indians attacked us," the captain answered, who felt anger flush his face on remarking the insolent expression which the speaker's countenance had assumed—"risk my life in the service of those to whom I have promised assistance and succour."

"Sir!"

"Yes," Leon continued; "for the rude task I am about to undertake demands utter self-denial; manhunting on the llanos and Pampas requires more than courage, for cunning and craft are needed, and if I refuse your help in this expedition, it is because your presence would impede my progress. Alone, I am certain of joining Tahi-Mari, but with you we should all be lost."

A feverish excitement had seized on the young man, who seemed most anxious to efface the suspicions of which he was the object.

"I have lived among the Indians who attacked us, and know their strange manners and customs. At this very moment, the forests are full of invisible eyes that watch and spy us; if we advance in a body toward the spot where they are, we may be certain of being all massacred. Believe me, in order to enter their encampment, I must glide like a snake through the lianas that grow in the forest. Such is the reason, gentlemen, why I refuse to let you accompany me, for you are ignorant of their infernal skill. And now I am at your disposal: if you absolutely insist on following me, I am at your orders; but, in that case, I answer for nothing, for we shall have every unfavourable chance against us."

These few words, uttered with an accent of conviction and frankness which could not be suspected, produced on the mind of the three men a favourable impression; no further objection was raised, and Leon was left at liberty to act as he pleased. Once the four gentlemen were agreed on this point, they had to turn their attention to the burial of the dead, and collecting the mules and horses, which the cries of the Indians and the gleam of the flames had terrified and driven from the camp.
