But this young lady had a bad heart, Señor, as I have already mentioned; and toward Don Mendo, to whom she owed everything, she did not behave well at all. So far from ministering to him in his infirmities, she left him wholly to the care of hired servants; when she made her rare visits to his sick-room she carried always a scented kerchief, and held it to her nose closely—telling him that the smell of balsams and of plasters was distasteful to her; and never, by any chance whatever, did she give him one single kind look or kind word. As was most natural, Don Mendo did not like the way that Doña Paz treated him: therefore, in the inside of him, he made his mind up that he would pay her for it in the end. And in the end he did pay her for it: as she found out when, on a day, that worthy old man was called to go to heaven and they came to read his will.

Doña Paz listened to the reading of the will with the greatest satisfaction, Señor, until the reading got to the very end of it: because Don Mendo uniformly styled her his beloved niece—which somewhat surprised her—and in plain words directed that every one of his three millions and a half of dollars should be hers. But at the very end of the will a condition was made that had to be fulfilled before she could touch so much as a tlaco of her great inheritance: and that condition was so monstrous—and all the more monstrous because Doña Paz was so rigorously elegant in all her doings, and so respectful of her own dignity—that the mere naming of it almost suffocated her with fright and shame.

And, really, Señor, that Doña Paz felt that way about it is not be wondered at, because what Don Mendo put at the very end of his will was this: "So to Paz, my beloved niece, I leave the whole of my possessions; but only in case that she comply precisely with the condition that I now lay upon her. And the condition that I now lay upon her is this: That, being dressed in her richest ball dress, and wearing her most magnificent jewels, she shall go in an open coach to the Plaza Mayor at noonday; and that, being come to the Plaza Mayor, she shall walk to the very middle of it; and that there, in the very middle of it, she shall bow her head to the ground; and that then, so bowing, she shall make the turn which among the common people of Mexico is called a 'machincuepa.' And it is my will that if my beloved niece Paz does not comply precisely with this condition, within six months from the day on which I pass out of life, then the whole of my possessions shall be divided into two equal parts: of which one part shall belong to the Convent of Nuestra Señora de la Merced, and the other part shall belong to the Convent of San Francisco; and of my possessions my beloved niece Paz shall have no part at all. And this condition I lay upon my beloved niece Paz that, in the bitterness of the shame of it, she may taste a little of the bitterness with which her cruelties have filled my dying years."

Well, Señor, you may fancy the state that that most proud and most dignified young lady was in when she knew the terms on which alone her riches would come to her! And as to making her mind up in such a case, she found it quite impossible. On the one side, she would say to herself that what was required of her to win her inheritance would be done, and done with, in no more than a moment; and that then and always—being rich beyond dreaming, and in her own right a marquésa—she would be the greatest lady in the whole of New Spain. And then, on the other side, she would say to herself that precisely because of her great wealth and her title she would be all the more sneered at for descending to an act so scandalous; and that if she did descend to that act she would be known as the Marquésa de la Machincuepa to the end of her days. And what to do, Señor, she did not know at all. And as time went on and on, and she did not do anything, the Mercedarios and the Franciscanos—being always more and more sure that they would share between them Don Mendo's great fortune—talked pleasantly about new altars in their churches and new comforts in their convents: and as they talked they rubbed their hands.

And so it came to the very last day of the six months that Don Mendo had given to Doña Paz in which to make her mind up; and the morning hours of that day went slipping past, and of Doña Paz the crowds that filled the streets and the Plaza Mayor saw nothing; and the Mercedarios and the Franciscanos all had smiling faces—being at last entirely certain that Don Mendo's millions of dollars would be theirs.

And then, Señor, just as the Palace clock was striking the half hour past eleven, the great doors of Don Mendo's house were opened; and out through the doorway came an open coach in which Doña Paz was seated, dressed in her richest ball dress and wearing the most magnificent of her jewels; and Doña Paz, pale as a dead woman, drove through the crowds on the streets and into the crowd on the Plaza Mayor; and then she walked, the crowd making way for her, to the very middle of it—where her servants had laid a rich carpet for her; and there, as the Palace clock struck twelve—complying precisely with Don Mendo's condition—Doña Paz bowed her head to the ground; and then, so bowing, she made the turn which among the common people of Mexico is called a machincuepa! So did Doña Paz win for herself Don Mendo's millions of dollars: and so did come into the soul of her the bitterness of shame that Don Mendo meant should come into it—in reward for the bitterness with which her cruelties had filled his dying years!

What became of this young lady—who so sacrificed propriety in order to gain riches—I never have heard mentioned: but it is certain that the street in which she lived immediately got the name of the Street of the Machincuepa—and the exact truth of every detail of this curious story is attested by the fact that that is its name now.

Perhaps the meaning of this word machincuepa, Señor—being, as Don Mendo said in his will, a word in use among the common people of Mexico—is unknown to you. The meaning of it, in good Spanish, is salto mortal—only it means more. And it was precisely that sort of an excessive somersault—there in the middle of the crowded Plaza Mayor at noonday—that the most proud and the most dignified Doña Paz turned!
