When nearly through the field, I perceived something glancing before us: it was water—a wide drain or ditch, a zequia for irrigating the field. Like the magueys, it ran transversely to our course.
“That will stop him,” thought I; “he must take to the right or left, and then—”
My thoughts were interrupted. Instead of turning either to right or left, the Mexican headed his horse at the zequia, and the noble creature rushing forward, rose like a bird upon the wing, and cleared the canal!
I had no time to expend in admiring the feat; I hastened to imitate it, and galloping forward, I set myself for the leap. My brave steed needed neither whip nor spur; he had seen the other leap the zequia, and he knew what was expected of him. With a bound he went over, clearing the drain by several feet; and then, as if resolved upon bringing the affair to an end, he laid his head forward, and stretched himself at race-course speed.
A broad grassy plain—a savannah—lay before us, and the hoofs of both horses, pursuer and pursued, now rang upon hard firm turf. The rest of the chase would have been a simple trial of speed, and I made sure of overhauling the mustang before he could reach the opposite side, when a new obstacle presented itself. A vast herd of cattle and horses studded the savannah throughout its whole extent; these, startled by our wild gallop, tossed their heads, and ran affrighted in every direction, but frequently as otherwise, directly in our way. More than once I was forced to rein in, to save my neck or my horse’s from being broken over a fierce bull or a long-horned lumbering ox; and more than once I was compelled to swerve from my course.
What vexed me most, was that in this zigzag race, the mustang, from practice perhaps, had the advantage; and while it continued, he increased his distance.
We cleared the drove at length; but to my chagrin I perceived that we were nearly across the plain. As I glanced ahead, I saw the chapparal near, with taller trees rising over it; beyond, I saw the swell of a hill, with white walls upon its summit. It was the hacienda already mentioned: we were riding directly towards it.
I was growing anxious about the result. Should the horseman reach the thicket, I would be almost certain to lose him. I dared not let him escape. What would my men say, if I went back without him? I had hindered the sentry from firing, and permitted to escape, perhaps a spy, perhaps some important personage. His desperate efforts to get off favoured the supposition that he was one or the other. He must be taken!
Under fresh impulse, derived from these reflections, I lanced the flanks of my horse more deeply than ever. Moro seemed to divine my thoughts, and stretched himself to his utmost. There were no more cattle, not an obstacle, and his superior speed soon lessened the distance between himself and the mustang. Ten seconds more would do it.
The ten seconds flew by. I felt myself within shooting distance; I drew my pistol from its holster.
