1790, commissioned Stadler to redeem from pawn a portion of the silver plate which had been pledged for the expenses of the journey and to renew the agreement for the remainder. In spite of a very strong suspicion that Stadler had purloined this pawn-ticket from Mozart's open cashbox, the latter was not deterred from assisting him in the following year towards a professional tour, both with money and recommendations, in Prague, and from presenting him with {MARRIED LIFE.} (310) a concerto (622 K.), composed only a few months before Mozart's death.[111] No doubt all this shows culpable weakness on Mozart's part--weakness incompatible with his duty to himself and his family. His household burdens were increased by many misfortunes, especially by the repeated and long-continued illnesses of his wife, necessitating an expensive sojourn in Baden for many successive summers. Her delicacy doubtless prevented such personal supervision of the household as was essential to its economical management. She failed also to acquire such an intellectual influence over her husband as to strengthen his capacity for the proper conduct of his affairs, and she had not strength of mind or energy to take the management of the household entirely into her own hands. She felt the discomfort keenly, saw the causes of it, but could not strive against them for any length of time. Without wishing to reproach her, we may say at least that had Constanze been as good a housekeeper as Mozart was a composer, things would have gone well with him. It must not be supposed that Mozart was blind to the advantages of good household management or wanting in the will to effect it; from time to time he made earnest endeavours after economic reform. In February, 1784, he began an exact catalogue of his compositions, in which he carefully entered every one of his works, until a short time before his death, with suggestions of the theme;[112] at the same time he began to keep an account book of his income and expenditure. André observes as to this account, which unhappily I have not been able to see, that Mozart entered his receipts--which included the profits on some concerts, on lessons to different persons of rank, and on a few of his compositions--on a long piece of paper. His expenditure he noted in a little quarto book, which he afterwards used {MOZART'S ACCOUNT-KEEPING.} (311) for writing English exercises and translations. His entries, while they lasted, were exact and minute. For instance, on one page we find:-- May 1, 1784. Two lilies of the valley... 1 kreutzer. May 27, 1784. A starling.........34 kreutzers. Then comes the following melody--[See Page Image] with the remark, "Das war schön!" It is easy to discover what so delighted him. On April 12 he had composed his pianoforte concerto in G major (453 K.), and soon after played it in public. The subject of the rondo is:--[See Page Image]
