At this juncture I also learned that Mr. Fenwick was ultimately to locate in Holland, where he was to join other secret service men in keeping a close watch of the movements of goods imported with the consent of Great Britain from North and South America. He was to ascertain whether any of these goods were finding their way into Germany, and, if so, in what quantity and under what conditions. By this time we had finished our luncheon. I was ready to leave the table and planned to do so as gracefully as possible. All I still wanted was some information about the confederates of Mr. Fenwick in Denmark. This was not difficult to obtain. These spies, or secret service men as they called themselves, had the impression that I was in the same line of work as Mr. Fenwick, except that I was to operate in Denmark. For this reason they gave me much information about commercial affairs which were not open for publication and supplied me with addresses of people in Denmark in whom I could confide. The session came to a close at about ten o'clock, after which I hurried to the place of my residence near the Battery, where I had engaged quarters. V--STORY OF A SEA VOYAGE FROM NEW YORK TO CHRISTIANA Before leaving New York I mailed several letters and many American newspapers to the Danish capital, addressing them in care of Hoved Post Kontor, Kopenhagen, Denmark. The letters had been given to me by Mr. Fenwick for identification among some people he knew and they later proved of much value to me in conducting my study of the work of spies and its effect upon commerce and the trend of the war. My purpose in mailing the letters and newspapers was to evade the possibility of losing them in case of detention and seizure of the ship before reaching the capital of Denmark, which was not entirely out of the range of probability. The ocean-liner _Frederick VIII_ was throbbing under the pressure of superheated steam when I arrived at the docks in Hoboken, shortly before two o'clock in the afternoon of September twenty-second. Everything was ready for her to put to sea in the long route across the northern part of the Atlantic. At the table to which the chief steward assigned me were one Danish officer of the steamship and seven passengers. The latter included one English, one German, two Belgian and three American citizens. The general conversation was in German, and this was pleasing to me, as it gave me an opportunity to cultivate the use of the Teutonic tongue with much effect. Among the passengers was Mr. Niels Petersen, who had been in Canada and had taken pictures at the principal seaports, such as St. John, Halifax, Quebec and Montreal. His photographs included views of harbors, bridges, railway terminals, stretches of highways and prominent buildings. He had been tracked to New York, where he was detected by British spies, and a telegram to Kirkwall by way of London demanded his arrest on the charge that he was guilty of espionage.
