The pursued party had now reached the eastern extremity of the lake. Before them stretched a vast plain, entirely destitute of timber or other covering. Only to the left appeared the outlines of a tract of chapparal, or low forest. The bandits, on looking forward, saw at a glance that the open ground would give them no advantage. Their horses might be swifter than those of their pursuers, but this was doubtful; and from the snorting heard at intervals behind them, they knew that one at least was capable of overtaking them. The bright moonlight enabled the pursuers to keep them in view--almost as if it had been noonday; and on the broad, treeless savanna, no hiding-place could be found. Their only hope then lay in being able to reach the timber, and finding concealment within the depths of the forest jungle. To accomplish this, however, it would be necessary for them to swerve to the left, which would give the pursuers an advantage; but there was no help for it, and Arroyo--whom fear had now rendered irresolute--rather mechanically than otherwise, turned towards the left, and headed for the chapparal. Despite the fiery passions that agitated him, Don Rafael still preserved his presence of mind. Watching with keen glance every gesture of the bandits, he had anticipated this movement on their parts; and, even before they had obliqued to the left, he had himself forged farther out into the plain, with a view of cutting them off from the woods. On perceiving them change the direction of their flight, he had also swerved to the left; and was now riding in a parallel line, almost head for head with Arroyo and Bocardo; while the shadow of himself and his horse, far projected by the declining moon, fell ominously across their track. In a few seconds more the snorting steed was in the advance, and his shadow fell in front of Arroyo. A sudden turn to the right brought Roncador within a spear's length of the bandit's horse, and the pursuit was at an end. "_Carajo_!" cried Arroyo, with a fierce emphasis, at the same time discharging his pistol at the approaching pursuer. But the bullet, ill-aimed, passed the head of Don Rafael without hitting; and the instant after, his horse, going at full speed, was projected impetuously against the flanks of that of the bandit, bringing both horse and rider to the ground. Bocardo, unable to restrain his animal, was carried forward against his will; and now became between Don Rafael and his prostrate foe. "Out of the way, vile wretch!" exclaimed Don Rafael, while with one blow of his sabre hilt, he knocked Bocardo from his saddle.
