He knew the zambo well enough to tell that his courage was now gone. The sudden loss of his comrade, and under such mysterious circumstances, had terrified the black, and would paralyse him almost beyond the power of resistance. He would think of nothing else but making his escape. Carlos knew that.

The quick intellect of the latter had taught him whence his enemies had come—from the lower or southern side of the grove. He had, indeed, been loosing for them in that direction, and, while scrutinising the underwood, had given most attention to that edge of the glade lying to the south. He conjectured that they would deem this the safest way to approach him, and his conjectures proved true.

Their horses would be left at some distance off, lest the stroke of their hoofs might alarm him. This, too, was his conjecture, and a just one. Still another, also just, was that the zambo was now making for the horses! This last occurred to Carlos as he saw the other rushing off into the underwood.

Just what the zambo was doing. Seeing his leader fall so mysteriously, he thought no longer of an encounter. Flight was his only impulse—to get back to the horses, mount and ride off, his one purpose. He had hopes that Carlos would not hastily follow—that he might escape under cover of the darkness.

He was mistaken. It was just to defeat this purpose that Carlos had galloped forth. He, too, was resolved to make for the horses!

Once in the open plain, he wheeled to the right, and rode round the grove. On reaching a point where he could command a view of the river he reined up. His object in doing so was to reload his rifle.

He threw the piece into a vertical position, at the same time groping for his powder-horn. To his surprise he could not get his hands upon it, and on looking down he saw that it was gone! The strap by which it had been suspended was no longer over his shoulders. It had been caught upon a branch, and lifted off as he had leaped from the tree!

Annoyed with this misfortune, he was about turning his horse to hurry back to the live-oak, when his eye fell upon a dark figure gliding over the plain, and close in to the fringe of willows by the river. Of course it was the fleeing zambo—there could be no doubt of that.

Carlos hesitated. Should he return for the powder-horn, and then waste time in reloading, the zambo might escape. He would soon reach the horses, and mount. Had it been day Carlos could easily have overtaken him, but not so under the night darkness. Five hundred yards’ start would have carried him safe out of sight.

The cibolero was full of anxiety. He had ample reasons to wish that this man should die. Prudence as well as a natural feeling of revenge prompted this wish. The cowardly manner in which these hired ruffians had dogged him had awakened his vengeance. Besides, while either lived, the outlaw knew he would have a dangerous enemy. The zambo must not escape!
