His labors in bringing out the "Zauberflöte" over, Mozart returned to the "Requiem" he had already commenced, but while writing he often had to sink back in his chair, being seized with short swoons. Too plainly was his strength exhausted, but he persisted in his solemn work. One bright November morning he was walking with Constanze in the Prater, and sadly pointing out to her the falling leaves, and speaking of death, with tears in his eyes, he added; "I well know I am writing this 'Requiem' for myself. My own feelings tell me that I shall not last long. No doubt some one has given me poison--I cannot get rid of this thought." With these gloomy fancies haunting his mind, he rapidly grew worse, and soon could not leave his room. The performances of the "Zauberflöte" were still going on, and extraordinarily successful. He took the greatest interest in hearing of them, and at night would take out his watch and note the time--"Now the first act is over, now is the time for the great Queen of Night." The day before his death he said to his wife, "Oh, that I could only once more hear my 'Flauto Magico!'" humming, in scarcely audible voice, the lively bird-catcher song. The same day, at two o'clock in the afternoon, he called his friends together, and asked for the score of his nearly completed "Requiem" to be laid on his bed. Benedict Schack sang the soprano; his brother-in-law, Hofer, the tenor; Gerl, the bass; and Mozart himself took the alto in a weak but delicately clear voice. They had got through the various parts till they came to the "Lacrymosa," when Mozart burst into tears, and laid the score aside. The next day (Sunday), he was worse, and said to Sophie, his sister-in-law, "I have the taste of death on my tongue, I smell the grave, and who can comfort my Constanze, if you don't stay here?" In her account of his last moments, she says: "I found Süssmayer sitting by Mozart's bed. The well-known 'Requiem' was lying on the coverlet, and Mozart was explaining to Süssmayer the mode in which he wished him to complete it after his death. He further requested his wife to keep his death secret until she had informed Albrechtsberger of it, 'for the situation of assistant organist at the Stephen Church ought to be his before God and the world.' The doctor came and ordered cold applications on Mozart's burning head.... The last movement of his lips was an endeavor to indicate where the kettledrums should be used in the 'Requiem.' I think I still hear the sound." HAYDN By C. E. BOURNE (1732-1809) [Illustration: Haydn.]
