R. M. Ballantyne 
In the Track of the Troops 

(Excerpt): "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."
