"My darling little wife, when I return, you must rejoice more in me than in the money I bring. 100 Friedrichs-d'or don't make 900, but 700, florins,--at least so I am told here. 2d. Lichnowsky being in haste left me here, so I am obliged to pay my own board (in that expensive place, Potsdam). 3d.----borrowed 100 florins from me, his purse being at so low an ebb. I really could not refuse his request--you know why. 4th. My concert at Leipzig turned out badly, as I always predicted it would; so I went out of my way nearly a hundred miles almost for nothing. You must be satisfied with me, and with hearing that I am so fortunate as to be in favour with the king. What I have written to you must rest between ourselves." His disappointment at the meagre financial returns from his tour was embittered by the serious illness of his Constanze and the drain upon his sympathy, his time, and his money. It was necessary for him to despatch in various directions a series of those pathetic begging letters that make up so much of his later correspondence. Shortly after the failure of his concert tour, desperation goaded him to set forth again. He writes again to his _Herzens Weibchen_ or his _Herzaller-liebstes_ with renewed hope: "I am quite determined to do the best I can for myself here, and shall then be heartily glad to return to you. What a delightful life we shall lead! I will work, and work in such a manner that I may never again be placed by unforeseen events in so distressing a position. Were you with me, I should possibly take more pleasure in the kindness of those I meet here, but all seems to me so empty. Adieu, my love! I am ever your loving Mozart. "P.S.--While writing the last page, many a tear has fallen on it. But now let us be merry. Look! Swarms of kisses are flying about--Quick! catch some! I have caught three, and delicious they are." This tour was again unsatisfactory. He came back almost poorer than he went. In March, 1791, Constanze had to go to Baden to take the waters for her health. Mozart wrote a letter in advance engaging rooms for her, and taking great care that they were on the ground floor. While Constanze was at Baden, Mozart was getting deeper and deeper into financial hot water, but his letters betrayed great anxiety that she should not be worried, especially as she was about to become a mother again. One of his letters to her was as follows; part of it is French, which I have not translated, and the rest in German, part of which also it seems more vivid to leave in the original:
