Before I had time to ask myself the question, the “Capitan” was repeated in a somewhat louder key, and I now perceived that the voice proceeded from above—from the azotea.

I wrenched my horse round, at the same time turning my eyes upward. I could see no one; but just at that moment an arm, that might have been attached to the bust of Venus, was protruded through a notch in the parapet. In the small hand, wickedly sparkling with jewels, was something white, which I could not distinguish until I saw it projected on the grass—at the same moment that the phrase “Un papelcito” reached my ears.

Without hesitation I dismounted—made myself master of the papelcito; and then leaping once more into the saddle, looked upward. I had purposely drawn my horse some distance from the walls, so that I might command a better view. I was not disappointed—Isolina!

The face, that lovely face, was just distinguishable through the slender embrasure, the large brown eyes gazing upon me with that half-earnest, half-mocking glance I had already noticed, and which produced within me both pleasure and pain!

I was about to speak to her, when I saw the expression suddenly change: a hurried glance was thrown backwards, as if the approach of some one disturbed her; a finger rested momentarily on her lips, and then her face disappeared behind the screening wall of the parapet.

I understood the universal sign, and remained silent.

For some moments I was undecided whether to go or stay. She had evidently withdrawn from the front of the building, though she was still upon the azotea. Some one had joined her; and I could hear voices in conversation; her own contrasting with the harsher tones of a man. Perhaps her father—perhaps—that other relative—less agreeable supposition!

I was about to ride off, when it occurred to me that I had better first master the contents of the “papelcito.” Perhaps it might throw some light on the situation, and enable me to adopt the more pleasant alternative of remaining a while longer upon the premises.

I had thrust the billet into the breast of my frock; and now looked around for some place where I might draw it forth and peruse it unobserved. The great arched gateway, shadowy and tenantless, offered the desired accommodation; and heading my horse to it, I once more rode inside the saguan.

Facing around so as to hide my front from the cocineras, I drew forth the strip of folded paper, and spread it open before me. Though written in pencil, and evidently in a hurried impromptu, I had no difficulty in deciphering it. My heart throbbed exultingly as I read:—
