In the midst of one of these shadowy aisles, I met or passed some one: I saw that it was a Mexican boy; but the sombre light, and the rapidity with which I was riding, prevented me from noting anything more. The lad shouted after me, uttering some words, which were drowned by the hoof-strokes of my horse. I deemed it some expression of boyish esprit, and, without heeding it, rode on.

Not until far out of sight and hearing did it occur to me that I knew the voice and the lad. I recollected a sort of errand-boy attached to the hacienda, and whom I had seen more than once at the rancheria. I now remembered the badinage of Wheatley, and would have returned to question the youth; but I had left him too far in the rear. After a moment’s reflection, I spurred on.

I soon arrived at the base of the hill on which stood the hacienda; and here leaving the main road, I followed a bridle-path that skirted the hill.

A few hundred yards brought me to the spot where I had last observed the object of my pursuit.

The hoof-track of the white horse now guided me, and upon his trail I entered the woods.

For some distance, it followed a well-trodden path—a cattle-track—but all at once it diverged from this, and struck off into a heavily timbered bottom, where not the semblance of path existed.

Keeping the trace in view, I rode after.

As I advanced, the timber grew thicker, and the path more difficult. A close underwood of arundinaria and sabal palms shut up the way and the view; trailing roots obstructed progress below; while higher up, the trelliswork of llianas, bamboo briars, sarsaparilla, and gigantic grape-vines, rendered it necessary to bend down in the saddle in order to pass onward.

To my surprise I noticed all this. For what purpose could she have chosen such a path? Was it indeed Isolina I had seen? A white horse and a scarlet manga are not uncommon things in Mexico. It might not be— But the hoof-print—

I dismounted and examined it: I knew it at a glance—it was that of the noble steed, and the rider could be no other than Isolina de Vargas.
