least idea of the delight with which I pursued this mechanical will-o’-the-wisp. Growing older, I took to chemistry, and here my love for research and analysis found ample scope, while the sufferings of my father’s household were intensified. I am not naturally cruel—far from it. They little knew how much pain their sufferings caused me; how earnestly I endeavoured to lessen or neutralise the nuisances which the pursuit of science entailed. But I could not consume my own smoke, or prevent explosions, or convert bad and suffocating odours into sweet smells. Settling down to this new pursuit with intense enthusiasm, I soon began to flow in my natural course, and sought to extend the bounds of chemical knowledge. I could not help it. The particular direction in which my interest ultimately became concentrated was that of explosives. After becoming acquainted with gun-cotton, nitro-glycerine, dynamite, lithofracteur, and other combinations of powerfully-explosive agents, I took to searching for and inventing methods by which these might be utilised. To turn everything to good account, is a desire which I cannot resist. Explosives naturally drew my attention to mines—tin-mines, coal-mines, and other commercial enterprises. They also suggested war and torpedoes. At that time I had not reflected on the nature of war. I merely knew it to be a science, cultivated chiefly by the human race, and that in its practice explosives are largely used. To “blow-up” effectively, whether in a literal or figurative sense, is difficult. To improve this power in war, and in the literal sense, I set myself to work. I invented a torpedo, which seemed to me better than any that had yet been brought out. To test its powers, I made a miniature fortification, and blew it up. I also blew up our groom, Jacob Lancey. It happened thus:— The miniature fortress, which was made of cardboard, earth, and bricks, was erected in a yard near our stables. Under its walls the torpedo was placed, and the match lighted. It was night and very dark. I had selected the hour as being that most suitable to the destruction of an enemy’s stronghold. The match was very slow in burning. Matches invariably are so in the circumstances. Suddenly I heard the sound of footsteps. Next moment, before I had time to give warning, Jacob Lancey came round the corner of the stables with a pitchfork on his shoulder, and walked right into the
