These matters gave a stronger impulse to my reading, and I devoured, with the greatest voracity, all books appertaining to my favorite subjects. Indeed, I became so engrossed in my employment, that I neglected my proper studies, avoided all society, all exercise, and out-door occupation. For weeks and weeks I shut my self up in my chamber, and refused to see anybody. I would sit for hours of a night, gazing upon the stars, and wondering if they exercised any control over the destinies of mankind. So nervous did this constant study and seclusion render me, that if a door were blown open by a sudden blast of wind, I trembled, and became as pale as death; if a withered bough fell from a neighboring tree, I was agitated, and unable for some seconds to speak; if a sudden footstep was heard on the stairs, I anticipated that my chamber-door would be immediately thrown open, and ere many seconds elapsed to be in the presence of a visitor from the dark and invisible world of shadows. I became pale and feverish, my appetite failed me, and I felt a strong disinclination to perform the ordinary duties of life. My friends observed, with anxiety and disquietude, my altered appearance; and I was recommended to change my residence, and to withdraw myself entirely from books. A favorable locality, combining the advantages of pure air, magnificent scenery, and retirement, was accordingly chosen for me, in which it was determined I should remain during the winter months. It was now the latter end of September.
