"Whoever may be the men who accompany my brother, to whatever tribe they may belong—even if they should be the most implacable enemies of my tribe—they have a right to my protection and my kindness. The rights of hospitality are sacred. Let my brother tell his companions that I do not wish to know anything about them; they are travellers—that is all—follow on. Here is my haak," said he, drawing a knife from his girdle, and handing it to the stranger; "if I betray my promise, my brother will bury it in my heart before all my assembled people. My brother and his companions will sleep this evening with the Guaycurus warriors."

The two warriors bowed, and then, reining back their horses, each returned at a gallop towards his people.

THE GUIDE.


Meanwhile, as we have seen in a preceding chapter, after the council held in the Valle del Tambo, Tyro had charged himself with the guidance of the little caravan, composed of two ladies, the French painter, the two gauchos, and himself.

As Tyro had foreseen, the travellers did not meet on this route any other obstacles than the material difficulties of the road—obstacles that by courage and perseverance they succeeded in overcoming.

The Guarani, as a warrior, thoroughly habituated to traverse an enemy's country, watched with extreme solicitude over the safety of those who had so frankly trusted to him, roaming continually round the caravan—in advance, in the rear, and on either side.

Every evening he camped in a position studied with care—a position which placed them, during their sleep, out of the range of a surprise.
