As we advanced, the aspect changed. The surface became freer of jungle; a succession of glade and thicket; in short, a “mezquite prairie.” Still advancing, the “openings” became larger, while the timbered surface diminished in extent, and now and then the glades joined each other without interruption.

We had ridden nearly ten miles without drawing bridle, when our guide struck upon the trail of the manada. Several of the old hunters, without dismounting, pronounced the tracks to be those of wild mares, which they easily distinguished from horse tracks. Their judgment proved correct; for following the trail but a short distance farther, we came full in sight of the drove, which the vaquero confidently pronounced was the manada we were in search of!

So far our success equalled our expectations; but to get sight of a caballada of wild-horses, and to capture its swiftest steed, are two things of very unequal difficulty. This fact my anxiously beating heart and quickly throbbing pulse revealed to me at the moment. It would be difficult to describe the mingled feelings of anxious doubt and joyous hope that passed through my mind, as from afar off I gazed upon that shy herd, still unconscious of our approach.

The prairie upon which the mares were browsing was more then a mile in width, and, like those we had been passing through, it was surrounded by the low chapparal forest—although there were avenues that communicated with other openings of a similar kind. Near its centre was the manada. Some of the mares were quietly browsing upon the grass, while others were frisking and playing about, now rearing up as if in combat, now rushing in wild gallop, their tossed manes and full tails flung loosely upon the wind. Even in the distance we could trace the full rounded development of their bodies; and their smooth coats glistening under the sun denoted their fair condition. They were of all colours known to the horse, for in this the race of the Spanish horse is somewhat peculiar. There were bays, and blacks, and whites—the last being most numerous. There were greys, both iron and roan, and duns with white manes and tails, and some of a mole colour, and not a few of the kind known in Mexico as pintados (piebalds)—for spotted horses are not uncommon among the mustangs—all of course with full manes and tails, since the mutilating shears of the jockey had never curtailed their flowing glories.

But where was the lord of this splendid harem?—where the steed?

This was the thought that was uppermost in the mind of all—the question upon every tongue.

Our eyes wandered over the herd, now here, now there. White horses there were, numbers of them, but it needed but a glance to tell that the “steed of the prairies” was not there.

We eyed each other with looks of disappointment. Even my companions felt that; but a far more bitter feeling was growing upon me as I gazed upon the leaderless troop. Could I have captured and carried back the whole drove, the present would not have purchased one smile from Isolina. The steed was not among them!

He might still be in the neighbourhood; or had he forsaken the manada altogether, and gone far away over the wide prairie in search of new conquests?

The vaquero believed he was not far off. I had faith in this man’s opinion, who, having passed his life in the observation of wild and half-wild horses, had a perfect knowledge of their habits. There was hope then. The steed might be near; perhaps lying down in the shade of the thicket; perhaps with a portion of the manada or some favourite in one of the adjacent glades. If so, our guide assured us we should soon have him in view. He would soon bring the steed upon the ground.
