Although dynamite in such quantities as a carload when ignited is almost certain to explode instead of merely burning, still, sometimes, even that quantity will take fire and burn up completely without exploding; while, at other times, a single stick of dynamite when ignited will detonate. EXPLOSIVE VAGARIES One of the old importers of picric acid in this country told me the following story: He sold about five tons of picric acid to a manufacturer of dynamite doing business at a certain place up the Hudson, for employment as an ingredient in a particular kind of high explosive. Not being very familiar with picric acid and the character of the exploder necessary to detonate it, the purchaser had poor success with it, and he called upon the importer with the grievance that he had been sold such a poor lot of picric acid that it was actually non-explosive, and was therefore practically worthless, and he wanted the seller to take it back immediately. The importer could not convince him that he was mistaken, although he insisted that it was only necessary to know how to explode it, and that, when properly detonated, it was one of the most powerful explosives in the world. "No," said the purchaser, "that picric acid you have sent me is not an explosive." He admitted he knew that picric acid was recognized as a very powerful explosive; but he was sure of one thing--that the picric acid that had been sent him was not an explosive. "Why," said he, "it is no more explosive than sand, and I want you to take it back." "All right," said the importer, "you may return me a sample of it, and I will submit it to the requisite tests, and if it proves an inferior lot I will take it back." That day, during the purchaser's absence, some workmen were moving a barrel of the picric acid in order to let a plumber mend a small leak in a lead pipe, which supplied the place with water. Over and about this lead pipe had been spilled a considerable quantity of picric acid, which had formed picrate of lead with the lead pipe. The friction from the barrel set off this picrate of lead, which in turn detonated the picric acid; and the whole five tons went off with such violence as amply to demonstrate its explosive qualities. The following day the purchaser returned to the importer with the complaint that that picric acid sold him was the most sensitive, most violent and treacherous explosive material in the world. The importer laughed, and reminded him of their previous conversation. But, as the dynamite factory had been demolished and several men killed, the purchaser did not respond very readily to the humor of the situation. THE TURKEY THAT WENT TO BED Possibly it may not be diverging too much from dynamite stories to tell of an experience of mine with a steam-cooker, which I invented away back in the eighties.
