The information I allude to was, that the ball was got up “by authority,” and would be upon a grand scale. Its object was political; in other words, it was to be the means of bringing about a friendly intercourse between the conquerors and the conquered—a desirable end. Every effort would be made to draw out the “native society,” and let them see that we Yankee officers were not such “barbarians” as they affected to deem, and in reality pronounced us. It was known—so stated my informant—that many families of the Ayankieados would be present; and in order to make it pleasanter for those who feared proscription, the ball was to be a masked one—un bailé de mascara.

“The Ayankieados are to be there! and she—”

My heart bounded with new hope: and I resolved to make one of the maskers—not that I intended to go in costume. In my slender wardrobe was a civilian dress proper cut, and tolerably well preserved: that would answer my purpose. The ball was to come off on the night following that on which I had word of it. My suspense would be short.

The time appeared long enough, but at length the he arrived, and, mounting my good steed, I started off for the city. A brisk ride of two hours brought me on the ground, and I found that I was late enough to be fashionable.

As I entered the ball-room, I saw that most of the company had arrived, and the floor was grouped with dancers. It was evident the affair was a “success.” There were four or five hundred persons present, nearly half of them ladies. Many were in character costumes, as Tyrolese peasants, Andalusian majas, Bavarian broom-girls, Wallachian boyards, Turkish sultanas, and bead-bedecked Indian belles. A greater number were disguised in the ungraceful domino, while not a few appeared in regular evening dress. Most of the ladies wore masks; some simply hid their faces behind the coquettish reboso topado, while others permitted their charms to be gazed upon. As the time passed on, and an occasional copita de vino strengthened the nerves of the company, the uncovered faces became more numerous, and masks got lost or put away.

As for the gentlemen, a number of them also wore masks—some were in costume, but uniforms predominated, stamping the ball with a military character. It was not a little singular to see a number of Mexican officers mingling in the throng! These were of course prisoners on parole; and their more brilliant uniforms, of French patterns, contrasted oddly with the plain blue dresses of their conquerors. The presence of these prisoners, in the full glitter of their gold-lace, was not exactly in good taste; but a moment’s reflection convinced one it was not a matter of choice with them. Poor fellows! had they abided by the laws of etiquette, they could not have been there; and no doubt they were as desirous of shaking their legs in the dance as the gayest of their captors. Indeed, in this species of rivalry they far outstripped the latter.

I spent but little time in observing these peculiarities; but one idea engrossed my mind, and that was to find Isolina de Vargas—no easy task amid such a multitude of maskers.

Among the uncovered faces she was not. I soon scanned them all, or rather glanced at them. It needed no scanning to recognise hers. If there, she was one of the mascaritas, and I addressed myself to a close observation of the dames en costume and the dominoes. Hopeless enough appeared the prospect of recognising her, but a little hope sustained me in the reflection, that, being myself uncovered, she might recognise me.

When a full half-hour had passed away, and my lynx-like surveillance was still unrewarded, this hope died within me; and, what may appear strange, I began to wish she was not there.

“If present,” thought I, “she must have seen me ere this, and to have taken no notice—”
