If the Allied general staffs had been provided with X-ray field-glasses, and had trained those glasses on a certain brownstone house in Massachusetts Avenue, between Fourteenth and Fifteenth Streets, in Washington, they would have been interested in the perfection of the German system of communication. They would have observed the secretarial force of the Imperial Embassy opening and sorting letters from confederates throughout the country, many so phrased as to be quite harmless, others apparently meaningless. The Embassy served as a clearing-house for all German and Allied air messages. Long before the war broke out the German government had seen the military necessity for a complete wireless system. Subsidies were secretly granted to the largest of the German electrical manufacturers to establish stations all over the globe. Companies were formed in America, ostensibly financed with American funds, but on plans submitted to German capitalists and through them to the German Foreign Office for approval. Thus was the Sayville station erected. As early as 1909 a German captain, Otto von Fossberg, had been sent to America to select a site on Long Island for the station. "The German government is backing the scheme," he told a friend, although the venture was publicly supposed to be under the auspices of the "Atlantic Communication Company," in which certain prominent German-Americans held stock and office. In 1911 an expert, Fritz von der Woude, paid Sayville a visit long enough to install the apparatus; he came under strict injunctions not to let his mission become generally known. Boy-Ed watched the progress of the Sayville station with close interest and considerable authority, and his familiarity with wireless threw him into frequent and cordial relationship with the United States naval wireless men and the Department of Commerce. On one occasion the Department requested a confidential report from a radio inspector of the progress made by foreign interests in wireless; the report prepared went to Germany before it came to the hands of the United States government. Again: the German government was informed in 1914 by Boy-Ed in Washington that the United States intended to erect a wireless station at a certain point in the Philippines; full details, as the Navy Department had developed them, were forwarded, and the German government immediately directed a large electrical manufacturer in Berlin to bid for the work. The site the United States had selected was not altogether satisfactory to Germany, for some reason, so the German government added this delicious touch: a confidential map of the Philippines was turned over to the electrical house, with orders to submit a plan for the construction of the American station on a site which had been chosen by the German General War Staff!
