This half explained to me why the animal had been going across country without a rider. Had it been bridled, I should have concluded that it had left its owner upon the field of Cerro Gordo, or parted with him in the hot pursuit succeeding that action.

But a bridle suspended from the saddle-bow—with bit, curb, and head-piece attached—forbade the conjecture; at the same time suggesting another: that the mustang must have made its escape from some temporary halting-place, where, like our own horses at Corral Falso, it had been unbridled to “bait.”

It was not this conjecture that influenced me to continue the chase; but the fact that the bridle-reins, suspended over the saddle-horn, had begun to trail among the animal’s feet, and promised, ere long, to prove an impediment to its flight. It was my observation of this that lured me on.

Chance, not prowess, was likely to give me the victory. But what mattered it, so long as there would be no one to witness the event?

My comrades would not know how I had effected the capture; and, instead of returning to them empty-handed—crest-fallen with chagrin—I should ride back in triumph; and so should Moro, the steel-grey mustang following at his heels.

Inspired by this pleasant anticipation, I once more struck the spur into the flank of my brave steed, which needed not such prompting. It was merely mechanical. Perhaps Moro knew as much, and forgave me for the unnecessary infliction.

Quite unnecessary, as it proved; for, at the very instant I was causing it, the riderless mustang, just as I had been wishing and expecting, became entangled in its trailing bridle, and rolled headlong upon the grass.

Before it could recover its legs, Moro was snorting by its side; and Moro’s rider, having forsaken his own steed, had looped the lazo around its neck, and secured it as a captive.

I was not left much time to congratulate myself on my good luck; for, in truth, it was luck, and only that, to which I had been indebted for the capture of the mustang.

Having secured the animal, as I supposed to a certainty, I was proceeding to re-insert its own bit between its teeth, in order the more easily to lead it along with me on the return journey to Corral Falso.
