Before the discovery by Nobel that the absorption of nitroglycerin by infusorial earth rendered it much less sensitive to shock, numerous attempts were made to bring it into general use, in liquid form, as a blasting agent, the most notable of which was during the digging of the Hoosac Tunnel. But, owing to its highly sensitive character, fatalities were numerous; while, furthermore, the necessity for perfect purity in order to render nitroglycerin stable--that is to say, to make it keep well--was not at first recognized, and many disasters were the result from explosions due to its decomposition. The first attempt to introduce nitroglycerin as a blasting agent into the United States was made by a young German student. He called the stuff "glonoin oil." He brought over a few hundred pounds in cans on the steamer with him, most of which he disposed of during his sojourn in the States. But his venture was not a financial success, and he was obliged, when he returned to Europe, to leave an unpaid board bill at a New York hotel where he had been staying. He had left one fifty-pound can of glonoin oil, which he let the hotel proprietor hold as security, but which, however, later developments proved to be insecurity. The glonoin oil occupied a place of honor in one corner of the barroom for several months after the departure of the German student. Decomposition having set in, yellow nitrous fumes began to emerge from the receptacle, the malevolent odor of which was soon noticed by one of the guests, who called the landlord's attention to the fact. Highly disgusted, the landlord picked up the can, walked to the front door, and threw it into the middle of the street. The act resulted in a miniature earthquake, which shattered the walls on both sides of the street, broke window-glass over a square mile, and landed the hotel proprietor in the hospital. THE LOADED CHINAMAN During the Russo-Japanese war a certain officer of the Czar, who was an impatient, overbearing person and a great martinet, had a Chinese servant whom he treated with the utmost harshness for the smallest delinquency, or for none at all. One of his favorite methods of inflicting punishment for offenses was to order the Chinaman to leave his presence, and, as the fellow went, to give him a hard kick. The Chinaman aired his grievances one day to a Japanese spy, whom he took to be a brother Chinaman. The Jap suggested padding the seat of the Chinaman's trousers to prevent further contusions, and this was done, the padding being furnished by the Jap. A rubber hot-water bag was filled with absorbent cotton containing all the nitroglycerin it would hold. A small exploding device armed with percussion caps was placed in the bag so that the nitroglycerin would be exploded by any sudden blow. The unfortunate Chinaman was wholly unaware of the nature of the padding.
