During the past winter there arrived in London a suspicious-looking metallic box, with a peculiar thumb-screw or button on the top. It was sent by mail, and was addressed to a prominent land owner. This gentleman had been on the watch for some explosive machine for some time, and when it was brought to him, he at once turned it over to the authorities for investigation. The police force, detective force and chemists were called in, and requested to ascertain the nature of the infernal machine, and, if possible, where it came from. Experts examined the box, and, with the aid of a cord attached to the suspicious button on top, pulled open the metallic box without explosion. The substance contained therein, was of a dark color, with a strong smell of ammonia. All kinds of tests were made by the experts, in order to ascertain of what kind of combustible it was composed. The odor was carefully noted, as well as the taste, and then there was a careful chemical analysis made, which was barren of result. In the midst of the general alarm, the London papers, with large scare-heads and astonishers, gave full and elaborate reports of the attempt upon the life of a prominent man, through the agency of a new and very peculiar machine, loaded with an explosive, of which scientists could gain no knowledge or information whatever. It looked as though the assassin was far in advance of science, or at least of professional chemists, and the matter was about to be given up in despair, when the following letter arrived from San Antonio, Texas, United States of America: "My Dear Sir:--I sent you by a recent mail, prepaid, a small metallic box of bat guano, from the caves of Texas, for analysis and experiment. Please acknowledge receipt of saine. "Morton Frewen." Then the experts went home. They felt as though science had done all it could in this case, and they needed rest, and perfect calm, and change of scene. They hadn't seen their families for some time, and they wanted to go home and get acquainted with their wives. They didn't ask for any pay for their services. They just said it was in the interest of science, and they couldn't have the heart to charge anything for it. One chemist started off without his umbrella, and never went back after it. When he got home he was troubled with nausea, and they had to feed him on cracker toast for several weeks. We tell this incident simply to vindicate America. The London papers did not give all the proceedings, and we feel it our duty to place the United States upon a square footing with England in this matter. Of course it is a little tough on the experts, but when we know our duty to our magnificent country and the land that gave us birth, there is no earthly power we fear, no terrestrial snoozer who can deter us from its performance.
