My life has for several years been a theatre of calamity. I have been a mark for the vigilance of tyranny, and I could not escape. My fairest prospects have been blasted. My enemy has shown himself inaccessible to entreaties, and untired in persecution. My fame, as well as my happiness, has become his victim. Every one, as far as my story has been known, has refused to assist me in my distress, and has execrated my name. I have not deserved this treatment. My own conscience witnesses in behalf of that innocence, my pretensions to which are regarded in the world as incredible. There is now, however, little hope that I shall escape from the toils that universally beset me. I am incited to the penning of these memoirs only by a desire to divert my mind from the deplorableness of my situation, and a faint idea that posterity may by their means be induced to render me a justice which my contemporaries refuse. My story will, at least, appear to have that consistency which is seldom attendant but upon truth. I was born of humble parents, in a remote county of England. Their occupations were such as usually fall to the lot of peasants, and they had no portion to give me, but an education free from the usual sources of depravity, and the inheritance, long since lost by their unfortunate progeny! of an honest fame. I was taught the rudiments of no science, except reading, writing, and arithmetic. But I had an inquisitive mind, and neglected no means of information from conversation or books. My improvement was greater than my condition in life afforded room to expect. There are other circumstances deserving to be mentioned as having influenced the history of my future life. I was somewhat above the middle stature. Without being particularly athletic in appearance, or large in my dimensions, I was uncommonly vigorous and active. My joints were supple, and I was formed to excel in youthful sports. The habits of my mind, however, were to a certain degree at war with the dictates of boyish vanity. I had considerable aversion to the boisterous gaiety of the village gallants, and contrived to satisfy my love of praise with an unfrequent apparition at their amusements. My excellence in these respects, however, gave a turn to my meditations. I delighted to read of feats of activity, and was particularly interested by tales in which corporeal ingenuity or strength are the means resorted to for supplying resources and conquering difficulties. I inured myself to mechanical pursuits, and devoted much of my time to an endeavour after mechanical invention.
