An A. P. L. operative wanted to know what these Germans were doing regarding the _Leviathan_. Of course, the boat was supposed to be absolutely guarded against entry by any stranger. This man, however, went to the gate and asked for the Commandant by nickname. The guard supposed he must be a friend of the Commandant, because of his familiarity, and naïvely let him through. The operative walked up and down the pier wondering how he could get on board, for he saw guards at the gangway. There was a pile of mailbags on the dock, so the operative stole over that way, picked up a mail sack and threw it over his shoulder. Near the gangway there was a group of soldiers and sailors engaged in an argument. As the operative approached, they separated, and he went through. He was dressed in civilian clothes, and had on a derby hat, but these did not seem to be suspicious facts. The operative walked on up the gangplank unmolested, and roamed all over the boat from top to bottom, still carrying the mailbag. Having done what any German could have done in the same circumstances, he started out, but near the gangway was stopped by a man who wore a watchman’s badge, and who spoke with a noticeable German accent. This man stopped the operative, who, upon being asked where he was going, replied that he was going off the boat. The watchman told him to get off in a hurry. He was still carrying his U. S. mail sack, which he replaced on the pile where he had got it. After that, he strolled out to the street again, satisfied that the guard around the _Leviathan_ might have been a trifle more airtight. As a matter of fact, while the sailing dates of the _Leviathan_ were jealously guarded, bets were made by the Germans on her sailing time out and back. Word came to an A. P. L. man that the _Leviathan_ was going to sail at 12:15 the next day. As this came from German sources, it seemed a useful thing to have the Government alter the sailing hour. The operative in this case strolled around in the vicinity of the _Leviathan_’s pier and talked with sailors, who freely told him the sailing hour. Then, in order to mystify the Government officers, the operative called up a certain Department and said over the ’phone that he was an Intelligence official of the Imperial German Navy, and wanted to know if it was true that the _Leviathan_ was to sail at 12:15 the next day. This caused some excitement. The operative then told whom he was, explaining that he had got that knowledge himself the previous evening. As a result, the sailing hour was changed several hours, and the _Leviathan_ got off safely.
