Kuepferle’s arrest was kept a secret for nearly two months. Meantime it is reported that Scotland Yard men were using the prisoner’s name as a means of communicating with German officials in Holland. In Kuepferle’s baggage, sheets of paper used for invisible ink were found. Imitating Kuepferle’s handwriting, the detectives were said to have written letters to German spy chiefs, between the lines of which they traced in invisible ink all sorts of questions asking further instructions. A rapid-fire correspondence is reported to have continued for many weeks. The prisoner is charged with having visited many English and Irish ports to investigate shipping and report to Germany the movements of transports. Dublin, Liverpool, and Belfast are said to be centers where he was active. His capture took place the day following the declaration of the German submarine blockade, February 18th. New Record Made by Wireless Phone. A new distance record for wireless telephony was established when P. N. Place, superintendent of the Scranton division of the Lackawanna Railroad, spoke from Scranton, Pa., to Frank Cizek, superintendent of the Syracuse division, who was in Binghamton, N. Y. The messages traversed sixty-three miles through a mountainous country. The achievement was made more notable by the fact that the messages exchanged were not brief greetings, but business communications, regarding the movement of trains. The Lackawanna trains between Scranton and Binghamton moved for several hours according to orders sent and received by the wireless telephone. Every word transmitted by the wireless was heard distinctly, according to L. B. Foley, superintendent of telephone, telegraph, and wireless of the Lackawanna, who was in charge of the experiment. Mr. Foley was jubilant over the achievement. Experiments with wireless telegraph and telephone have been conducted by the Lackawanna under his direction for more than a year. The more recently recorded demonstration previous to this was on February 9th last, when wireless-telephone conversations were carried on between the station at Binghamton and a moving train at Lounsberry, N. Y., twenty-six miles away. The immediate object of the Lackawanna’s experimenters now is to increase the distance between a fixed station and a moving train to fifty miles, and that between two fixed stations to 150 miles, the distance between Hoboken and Scranton. “I firmly believe,” Mr. Foley said, “that we shall be talking from our station in Hoboken to our station in Scranton within the next three or four weeks.”
