The inventor was so fortunate as to have a "pull" with the congressman from his district, and through this influence he succeeded in getting Government permission for a test of his piece at Sandy Hook. In the meantime he had strengthened the powder chamber of his gun by driving on several steel hoops, in order to use larger charges of powder. So confident was he of the safety of his system of throwing high explosives, that, when the officers at Sandy Hook insisted on his retiring with them behind the bomb-proof during the firing of the piece, he balked and insisted that he be permitted to stand by his gun while firing it, as he had done in his previous experiments on Staten Island. He was not in the least impressed with any possibility of danger by reason of the fact that he was now using a much larger powder charge. The officers, however, were obdurate. They told him bluntly that he must either stand behind the bomb-proof, or his gun would not be tested. He replied: "Very well, if Uncle Sam does not want my gun enough to let me test it in my own way, then I will sell it to foreign governments, and make Uncle Sam feel very sick and sorry." On his return with his gun to Staten Island, he gathered together a party of neighbors and some representatives of the press, to witness the experiments that Uncle Sam had missed. When the gun was ready to fire, the little knot of spectators frayed out, and peeped from cover. There was but one shot, which was not a shot, but an explosion. After waiting for some time for the inventor to come down and explain, the spectators went home, disappointed. THE DOG THAT ATE DYNAMITE In the early nineties I was experimenting with a new fulminate compound as a detonator for fuzes in high explosive projectiles. The compound consisted of fulminate of mercury with gelatinated guncotton and nitroglycerin. One of my workmen had a pup of a miscellaneous breed, which would eat anything under the sun that he could masticate, and when anything was thrown into his mouth not too big for him to bolt, he swallowed it without the formality of chewing it. One day his master gave him about half a pound of this fulminate compound. Another of the workmen put some metallic sodium and dry fulminate into a gelatin capsule, stuck this into the end of a quintuple dynamite cap, wrapped the whole thing in a piece of meat, and, calling the dog out into the field, made him stand up and "speak" for it. Then he dropped it into the dog's throat and it was swallowed at a gulp. The next instant, the latter workman's own dog, which he prized very highly, came upon the scene and entered into a very brisk wrestling-bout with the dog that had been charged. Before he could call him away, there was a terrific explosion, and both dogs vanished from this vale of tears. INSECURE SECURITY
