But his plans went all wrong. In the first place, the pestilent fever, which he fought with giant doses of quinine, proved very intractable and held him in its grip for months. He was unable to work and fell into a sort of mental coma. In a letter of November 13 he describes himself as eating Peruvian bark like bread; and six weeks later he was still suffering from the effects of his unlucky midsummer plunge into the miasmatic air of Mannheim. In other ways, too, the new situation proved a disappointment. Social demands involved him in expenditures far in excess of his modest calculations, while the intervals of relief from physical incapacity were filled with a hundred distractions which left him no time for sustained mental effort. And so he drifted into the winter without accomplishing anything more notable than the final revision of 'Fiesco'. About this time he was elected a member of the so-called 'German Society', a learned body which enjoyed the protection of the Elector. This little honor was highly valued by Schiller, since it made him a citizen of the Palatinate and gave him an assured social status. On the other hand, his emergence into the light of day as a respectable functionary was not without its disadvantages, since his creditors now became importunate. There were pressing duns from Stuttgart and from Bauerbach, but the debtor could not pay. He became involved in a painful correspondence with his father, who had undertaken to guarantee a small debt of his son provided that another larger one be paid so and so. When this hope failed, the old captain lost patience and began to deal out counsel, reproof and warning with a lavish hand. He recommended his son to save the pennies and live more economically; to return to medicine; to marry a wife; to remember his Creator, and so on. To all of which the perplexed Friedrich could only reply with fresh promises, excuses and recommendations of patience. In like manner he put off Frau von Wolzogen until she began to lose faith in him. A sharp letter from her brought him to his knees with a humble apology, but it was years before he could pay his debt to her.
