As soon as the shadows of night began to fall, Ronie prepared to start anew on his expedition, Jack and the two Venezuelans accompanying him, the prisoners being left in care of the followers of Don Isadora. The ride for half an hour continued through an archway of trees growing on the plantation of their host, when Riva declared that they had reached the limit of his broad domains. They soon after entered a valley, the hoof-strokes of their horses muffled by the soft, spongy earth.
It must have been nearly midnight, for they had ridden several miles up and down the country without discovering any trace of the enemy, when Riva, who was slightly ahead of the others, abruptly paused in his advance. Ronie quickly gained his side, where he stopped to learn the cause of this unexpected halt. It required no words on the part of the guide to explain his action, as he mutely pointed with his right hand to a ravine, or gorge, running parallel with the road. The sound of human voices came up distinctly to the ears of Ronie.
Handing the rein of his horse to his companion, he silently dismounted, and crept toward the brink of the chasm overhanging the place. In a moment the light of a camp-fire struggled dimly upward through the thick foliage, while with the sound of voices came the noise and confusion of a body of men moving about.
"I believe it is an encampment of El Capitan," he whispered to Jack, who had joined him. "I have a mind to get a little closer."
"I need not tell you to be careful," said Jack. "Can I go with you?"
"I do not believe you had better, Jack. I will not be gone long. From the sounds, I judge the party below are about to start on some midnight raid."
Before he had finished speaking, Ronie began to lower himself down the descent, moving with such care that he made no noise. The bank did not prove to be perpendicular, but its smooth side sloped gently away to its foot, and covered as it was with rank vegetation, Ronie had little difficulty in descending, except that at places the matted mass of growth was so dense that he could penetrate it only after persistent effort. At the end of five minutes he found himself so near the bottom that his next step was upon the thatched roof of one of the primitive buildings that seemed to form a row on this side.
