These words went through Frau Schimmel like a knife, and as Melchior stood there looking up at the ceiling as if he expected it to open and disclose to him a sight of Heaven, he seemed so great, and unapproachable, and apart, that she feared him, though in years gone by she had tucked his luncheon into his knapsack before sending him off to school, and tremblingly she yielded to his will as she had done before to his father's and swore again a solemn oath never to reveal what she might see or hear concerning the elixir. This vow oppressed Frau Schimmel and she breathed more freely when he began to talk about things within the range of her comprehension, about the details of the housekeeping, and the laboratory on the second floor with the big furnace. He must find an assistant who would be silent and discreet and Frau Schimmel knew of one whom she could recommend, for her husband did not enjoy his newly acquired leisure; he had been so used to blowing a furnace and decocting medicines that he could not give up the occupation and consequently she could not roast so much as a pigeon without having his grim and blear-eyed visage peering over her shoulder. The sensible woman foresaw that idleness would soon render the old bridegroom discontented, and Doctor Melchior, who remembered the silent man and his skilful hands, was very easily persuaded to give him a trial. At the back of the house there was a cheerful suite of rooms where the housekeeper and the apprentices had formerly lived. Melchior now put this apartment at the disposition of the old couple. Frau Schimmel would lend her aid to his wife, for Frau Bianca understood neither German nor the management of a German household, while from Herr Schimmel he anticipated the best particularly as he--the doctor--meant to devote himself at first entirely to the discovery of a remedy for his wife, whose condition filled him with the deepest apprehension. The new laboratory was presently the scene of the most zealous labours, and Herr Schimmel was delighted with his new position, for no apothecary and chemist had ever before had such a well-fitted furnace and such delicate scales and instruments to work with; and if he did not understand what was the end of so much weighing and fusing and distilling, or what the remedies were that the doctor was always decanting from the boiling liquids, yet the occupation made the long summer days pass most pleasantly, for he had none of that love of the open air that most Leipzigers bring into the world with them. Since his apprenticeship, and a whole lifetime had passed since then, he had left the apothecary shop only twice a year to take a holiday, and on none of these occasions had he ever seen green trees, for his "outings" as he called them, fell, according to his own wish, on the festival of the "Three Kings" in January, and on the twenty-seventh of March which was his saint's day, his name being Rupert.
