There were clouds in the sky at sunset, and every prospect of a storm; the wind howled through the trees and rattled the doors of the old house. I sat till late watching the collecting clouds which were rolling on in turbulent masses, and very low, till all was dark, as the last rent was filled, through which the moon had been shining. It was a terrible storm, the worst I had ever known, and Catalina came to my door at about two o'clock, in great fright, saying that she had seen a figure like Madre Mareno, going by the house as if floating in the air, and had heard a loud report as if there had been thunder in the distance, coming from Tamalpais. I could hear the rumbling and could not tell what it was; but I laughed at her fears and told her that it must have been a shadow, for no human being even a witch, would be out in such a night, if they could help it. Catalina went back to her room, but was far from reassured, and sat the rest of the night with her beads in her hand, praying by candle light. The next morning the storm was over, though through the sky the clouds were driving fast, but the rising sun touched them with gold and all the trees looked bright and new. Early, after breakfast, I gathered some flowers, and, mounting my mare, rode down to Madre Moreno's cottage. The storm seemed to have been more severe here than at the rancho, for the garden was destroyed and the vines by the house were hanging, torn from the trellises. Knocking at the half open door, I waited some minutes, but receiving no answer, stepped into the room. Upon the table lay a sheet of paper, I took it up to read what was written on it, thinking it would tell where the Madre and Ysidria had gone. All that was upon it was my name, but under the sheet was an envelope addressed to me. I hurriedly broke the seal and spread the sheets before me; they read-- My dear Carlos: Scarcely do I know how to begin this letter to you, whom I love so much. My aunt, Ambrosia, came to me last night, soon after you left me at the gate; she was smiling and very happy, and resting her hand on my shoulder said: "Ysidria thou hast done well, thou couldst not have done better had I trained thee to it." I was surprised at her manner, and asked her to explain. She sat down beside me and taking my hand in hers began: "I know thou art willing to do much for thy old aunt, and I have made thee, unknowingly, do it, though then wilt not blame me when I tell the why I have." She then related to me a tale of her father's time, when he had some trouble with your grandfather, and of the curse which she had pronounced upon each generation of de Sotos; you know all this. I listened in surprise and disgust, for she seemed to gloat over the thought of avenging the fancied wrong.
