Frederic was not gifted with surpassing intelligence nor with especial strength of comprehension; his intellectual abilities were small, but in their stead, Nature had given him a giant body, and replaced his other defects by a boundless good nature and a really touching devotion to his master. But quite in contrast to him, he had a most decided inclination to associate with others, and was delighted to employ for others, the abundant leisure which the professor allowed him; and so he helped the doctor's wife in the house, and the doctor in the garden. In this way he had gradually become a sort of factotum for both, without whose help nothing could be done, and it had been he who, through hours of exertion, and an expenditure of all his powers of invention, had prepared that unsuccessful welcome for the young American. Since that scene he always avoided her, half-timidly, half-resentfully. CHAPTER III. Was it Sickness or----? June, with its oppressively hot days, was at an end. In Professor Fernow's lodgings it was as silent as a church on a week-day; nothing moved here, not a sound broke the profound stillness that reigned in these apartments. One room was like another; book-case succeeded book-case, and upon each stood volumes in endless rows. The curtains were let down, a dim twilight prevailed. The genius and the science of centuries were heaped together here, but not a single fresh breath of air intruded into this solemn seclusion. In this study, which differed from the other rooms in nothing but perhaps a still greater mass of books, sat the professor before his writing table, but he was not at work; pen and paper lay unused before him; his head thrown back against the upholstery of his easy chair, his arms crossed, he gazed fixedly at the ceiling. Perhaps it was the green window curtains that made his face appear so strangely pale and ill, but his bearing also expressed an infinite weariness, as if both mind and body were wrought to their utmost tension, and his eyes betrayed nothing of that intensity of thought--which is perhaps just about to solve some scientific problem; there lay in them only that melancholy, purposeless reverie which so often absorbs the poet, so seldom the man of science. The door opened, and softly as this had happened, the professor trembled with that susceptibility peculiar to very nervous persons; Doctor Stephen appeared on the threshold, and behind him the anxious, care-worn face of Frederic was visible. "Good evening," said the doctor entering the room. "I have come to give you another lecture. You are not so well to-day, are you?" The professor glanced at him in surprise, "You are mistaken, doctor! I find myself quite well. There must be a misunderstanding, I did not send for you?"
