The latter reflected for an instant; then, turning to the young man, he answered him with a significant toss of the head:

"Curumilla is a prudent man. We have lived together for nearly fifteen years, and I have always found it best to follow his advice. Only once I wanted to have my own way, and then I all but lost my scalp. We will mount, Don Pablo. The chief has his reasons for acting as he is now doing, as the result will in all probability prove."

The hunters leaped into the saddle, and, after a farewell glance at the Teocali, where their friends were resting, they let their horses feel the spur.

"In what direction are we going?" Don Pablo asked.

"Let us first gain the riverbank," Valentine answered. "So soon as we have got there, we shall see what we have to do. But, mind we do not separate; for in the darkness it will be almost impossible to find each other."

On the prairies, the only roads that exist, and can be followed, are paths traced for ages by buffaloes, elks, and wild beasts. These paths form labyrinths; of which the Indians alone hold the thread; hunters, however well acquainted they may be with the prairies, only enter them with the utmost precautions. When they fancy they recognise a path, they will not leave it under any pretext, certain that if they Were so imprudent as to turn to the right or left, they would not fail to lose themselves, and have infinite difficulty in finding their road again.

Valentine was, perhaps, the only white hunter on the prairies who, owing to the profound knowledge he possessed of the desert, could enter this maze with impunity. However, as all the paths inevitably lead to the banks of rivers, and this direction was the one the little party was to follow, Valentine's remark was only intended to moderate Don Pablo's ardour, and compel him to march at his side.

After a hurried ride of two hours, the hunters at length found themselves on the banks of the Gila, which rolled its yellow and turbid waters along beneath them. At the moment when they reached the river, the sun rose majestically on the horizon in a mist of purpled clouds.

"Let us stop here a moment," Valentine said, "in order to form our plan of action."

"We do not need a long discussion for that." Don Pablo replied.
