But as the men watched they picked up on the staff at the stern of the incoming craft the Royal German ensign. A German submarine! Be assured that enough interest in German craft of the sort had been aroused in the two years and eight months of war to insure the visitor that welcome which is born of intense interest. The submarine, the U-53, held over toward Beaver Tail and then swung into the narrow harbor entrance, finally coming to anchor off Goat Island. The commander, Captain Hans Rose, went ashore in a skiff and paid an official visit first to Rear-Admiral Austin M. Knight, commander of the Newport Naval District, and then to Rear-Admiral Albert Gleaves, chief of our destroyer flotilla. Subsequent testimony of that German commander was that the American naval officers appeared somewhat embarrassed at the visit, suggesting men who were confronted by a situation which they were not certain how to handle. The statement of the German officer had a humorous sound and may have been humorously intended. In any event. Admiral Knight and Admiral Gleaves were very polite, and in due course paid the Germans the courtesy of a return visit, And while the submarine lay in the harbor the crew came ashore and were treated to beer by the American sailors, while crowds of curious were admitted aboard the submersible and shown about with the most open courtesy. Captain Rose said he had come to deliver a letter to Count von Bernstorff, the German Ambassador, but such a mission seemed so trivial that rumor as to the real intentions of the craft was rife throughout the entire country. There were suspicions that she had put in for fuel, or ammunition, or supplies. But nothing to justify these thoughts occurred. The U-53 hung around through the daylight hours, and at sunset, with a farewell salute, put to sea. Did our naval officers think this was the last of her? Possibly, but probably not. They knew enough of the Germans to realize, or to suspect, that their minds held little thought those days of social amenities and that such calls as were made upon neutrals contained motives which, while hidden, were none the less definite. The night brought forth nothing, however, and the Navy Department was beginning to feel that perhaps after all the U-53 was well on her way to Germany, when early the following morning there came to the radio-station at Newport an indignant message from Captain Smith of the Hawaiian-American liner _Kansan_. He asked to know why he had been stopped and questioned by a German submarine which had halted him in the vicinity of the Nantucket light-ship at 5.30 o'clock that morning. He added that after he had convinced the submarine commander as to the nationality of his ship, he was permitted to proceed.
