He would not allow himself to be quieted, until he had carried the dearest things he possessed, a few dozen of his most valuable books, to an antiquary, and thus defrayed the most pressing necessities for several weeks. Besides this, as the lectures had not yet commenced, he plunged headlong into all kinds of remunerative work, criticisms upon new books and contributions to scientific journals, and remained persistently at home all day long, with the exception of a short afternoon walk, never losing thought of Balder amid all his work. No one interrupted this strict seclusion except the faithful doctor, Mohr, who came daily for several hours to play chess, and Reginchen, who brought up the meals. Some change seemed to have taken place in the child, which transformed her whole nature in a mysterious, but very charming manner. She no longer sang and glided about like a young bird, or even prattled in her half childish, half motherly way to Balder, whom she now had to nurse; but the thoughtful, somewhat absent and sorrowful expression her countenance now wore, undoubtedly suited it better than her former wholly unshadowed mood. She seemed to have grown an inch taller, her face was perceptibly narrower, her cheeks less blooming, but suffused with a delicate glow from within. Moreover she was often found, as if spell-bound, standing still in the midst of a task gazing steadily into vacancy. When Balder asked what she was thinking about, she blushed crimson and laughed in an embarrassed way, but the next instant her face again wore a strangely quiet expression, such as no one had ever seen before. Even Edwin, who usually noticed her but little, remarked her altered manner. "Our little house swallow is thinking of building a nest," said he. "You'll see, Balder, before next spring she'll leave us to become her own mistress. It's a pity! I can't imagine the tun without this wandering ray of sunlight."
