"Certainly, caballero, since you do not employ us."

The young man fixed on the bandits—who this time supported it with erect heads—a look of singular expression, and resumed:

"Very well, I admit the first reason; now for the second."

"Pardon, caballero, this is the second: we have now stopped near the Rio Guachipas, have we not?"

"As to that, you ought to know better than I."

"Yes, it is the Rio Guachipas," said Tyro, who had arrived, and who seated himself near his master.

"Very well," resumed Mataseis, bowing courteously to the Guarani, "we have this morning traversed the Rio Dulce."

"What does that signify?" interrupted Emile.

"Pardon, señor; the Rio Dulce is in the province of Tucumán."

"The Rio Guachipas also," added the Guarani.
