I feel exquisite pleasure in dwelling on the recollections of childhood, before misfortune had tainted my mind and changed its bright visions of extensive usefulness into gloomy and narrow reflections upon self. Besides, in drawing the picture of my early days, I also record those events which led, by insensible steps, to my after tale of misery, for when I would account to myself for the birth of that passion which afterwards ruled my destiny I find it arise, like a mountain river, from ignoble and almost forgotten sources; but, swelling as it proceeded, it became the torrent which, in its course, has swept away all my hopes and joys.
