Mark Twain wrote a story that summer in Elmira, in the little octagonal study, shut in now by trees and overgrown with vines. "A Dog's Tale," a pathetic plea against vivisection, was the last story written in the little retreat that had seen the beginning of "Tom Sawyer" twenty-nine years before. There was a feeling that the stay in Europe was this time to be permanent. On one of the first days of October Clemens wrote in his note-book: "To-day I place flowers on Susy's grave--for the last time, probably --and read the words, 'Good night, dear heart, good night, good night.'" They sailed on the 24th, by way of Naples and Genoa, and were presently installed in the Villa Reale di Quarto, a fine old Italian palace, in an ancient garden looking out over Florence toward Vallombrosa and the Chianti hills. It was a beautiful spot, though its aging walls and cypresses and matted vines gave it a rather mournful look. Mrs. Clemens's health improved there for a time, in spite of dull, rainy, depressing weather; so much so that in May, when the warmth and sun came back, Clemens was driving about the country, seeking a villa that he might buy for a home. On one of these days--it was a Sunday in early June, the 5th--when he had been out with Jean, and had found a villa which he believed would fill all their requirements, he came home full of enthusiasm and hope, eager to tell the patient about the discovery. Certainly she seemed better. A day or two before she had been wheeled out on the terrace to enjoy the wonder of early Italian summer. He found her bright and cheerful, anxious to hear all their plans for the new home. He stayed with her alone through the dinner hour, and their talk was as in the old days. Summoned to go at last, he chided himself for staying so long; but she said there was no harm and kissed him, saying, "you will come back?" and he answered "Yes, to say good night," meaning at half-past nine, as was the permitted custom. He stood a moment at the door, throwing kisses to her, and she returned them, her face bright with smiles. He was so full of hope--they were going to be happy again. Long ago he had been in the habit of singing jubilee songs to the children. He went upstairs now to the piano and played the chorus and sang "Swing Low, Sweet Chariot," and "My Lord He Calls Me." He stopped then, but Jean, who had come in, asked him to go on. Mrs. Clemens, from her room, heard the music and said to Katy Leary: "He is singing a good-night carol to me." The music ceased presently. A moment later she asked to be lifted up. Almost in that instant life slipped away without a sound. Clemens, just then coming to say good-night, saw a little group gathered about her bed, and heard Clara ask: "Katy, is it true? Oh, Katy, is it true?" In his note-book that night he wrote:
