THE LATEST USE OF PHOTOGRAPHY. BY J. F. S. Multitudinous as are the practical applications of photo graphy, yet hardly a day passes but some new use or application is heralded in the daily press. So great is this range, that it gravitates all the way from the discovery of celestial phenomena millions of miles from the earth, down to the designing adventuress in Chicago who had her love letters photographed for use in a breach of pro mise suit, for fear that the originals might be written in unstable ink. The latest announcement now comes from Germany, and the scheme will, without doubt, be im proved upon in the future. The opening scene is laid in a railway train running from Stettin to Berlin. Among the passengers was a young man, Isidore Griinschnabel, the only son of a wealthy clothing dealer in the former city, who, in addi tion to his extensive business, prided himself upon being a “ Geheimer-geheim commercien rath” of his native town. The young man was on his way to the imperial city with a well filled wallet, nominally to secure some job lots for his father’s establishment; but in reality, as it afterwards turned out, his main object was to sec life in Berlin, which city, it may be remembered, is itself on the Spree. In the train, this verdant scion of an old but commer cial house became acquainted with a fellow-traveller—one Fritz Schnepperle—who was by birth a Berliner, by occu pation a travelling “ commis,” or salesman, and, like many of his class, a sharper, always open for opportunities. During the journey, the young Griinschnabel made a con fidant of his new-found friend, which culminated in asking him to act as his guide through the intricate mazes of the metropolis of the Hohenzollern. Welland attentively did Schnepperle listen, and acceded to his friend’s request without much urging. On their arrival in Berlin, the young Stettiner, under the guidance of his new-found friend, devoted himself so assiduously to his studies that, ere twenty-four hours had rolled around, young Griinschnabel was confined to his room at the hotel with a pronounced headache. The patient reader will, no doubt, ask, “ What has all this to do with photography ? ” A little patience, and the denouement will bring the answer. The designing companion, Schnepperle, after leaving his young companion helpless in bed, now sent a telegram to Griinschnabel, Senior, stating that he had run across some large job lots, but was short 500 marks cash, which he wanted sent by return mail without delay, signing the name of Griinschnabel, Jun. The father, who is also an honorary member of a photo graphic society, at once sent the money to the designated postal station in Berlin ; but, with a latent suspicion that perhaps all was not right, he mailed at the same time a letter to the official at the station, enclosing a photograph of his son, and requesting that the money letter be de livered only to the original of the enclosed photograph. The following day the personator called at the station for the letter. The official, Herr Spiihrnase, who entered into the spirit of the matter, compared the person with the photograph. A glance was sufficient, and the ever-pre sent policeman was at once called into requisition. On the following day the prisoner was arraigned before the Imperial Schwur Gericht, and, on being confronted with the evidence and photograph, was found guilty of attempted swindle, and sentenced to a term of six years at hard labour in the penitentiary at Spandau. During the course of the trial, the judge, Herr Von Biirstenbinder, took occasion to pay a high tribute to photography, and the great aid which it lent to the police department in detecting criminals and assisting in the administration of justice. In the present case, the honourable judge stated that photography had proven it self capable of even a higher scope, viz., as an agent to prevent the successful accomplishment of a well-laid scheme to fraudulently obtain a sum of money. After congratulating the postal official upon his vigilance, the judge stated that he hoped to see the day when photo graphy would be regularly used in connection with iden tification in financial transactions; further, that here opened a field which, so far, had been overlooked in the past; also that he personally would request the “ Photo- graphische Verein zu Berlin” to formulate a practical scheme for the purpose, and bring the matter before the Imperial Chancellor for adoption throughout the length and breadth of the German realm.
