The indictment of Stahl does not mean that the Government's investigation of the Lusitania affidavits, and the way in which they were procured, is at an end. On the other hand it is proceeding vigorously. Three witnesses, all Government officials, were before the Grand Jury yesterday in connection with the case. Heinz Hardenberg, who was found in Cincinnati a week ago today and brought here to be examined by the Grand Jury, has not yet appeared before that body, although the Government agents insist they can produce him when his testimony is desired. THE NEBRASKAN CASE. _An Associated Press dispatch dated at London on May 26, 1915, reported:_ The American steamer Nebraskan, Captain Greene, from Liverpool May 24 for Delaware Breakwater, was torpedoed yesterday evening by a submarine at a point forty miles west-southwest of Fastnet, off the south coast of Ireland. [Captain Greene's report, given below, says the Nebraskan was "struck by either mine or torpedo."] The sea was calm at the time. The crew at once took to the boats and stood by the steamer. It was soon ascertained that the Nebraskan was not seriously damaged, but she had been struck forward, and her foreholds were full of water. The crew returned on board and got the vessel under way. No lives were lost among the crew. The Nebraskan did not carry any passengers. This information was received at the British Admiralty in London, and it was at once communicated to the American Embassy. Immediately she was struck the Nebraskan began calling for help by wireless. Brow Head received the wireless communication at 9 P.M. yesterday from Crookhaven. A message to Lloyd's from Kinsale, Ireland, says that the Nebraskan passed that point at 11 o'clock this morning. She was down at the bows, but was proceeding under her own steam, and flying the signal: "I am not under control." The vessel passed Queenstown in the afternoon on the way to Liverpool. She was proceeding at eight knots. A message to The Star from Liverpool says that the name and nationality of the Nebraskan were painted in large letters on her sides. She was in water ballast. A message to Lloyd's says that an armed trawler went to the assistance of the Nebraskan and stood by her all night. The report that the Nebraskan had been torpedoed caused surprise to American officials here. Apparently the affair occurred before 9 o'clock last night. Last evening was clear, and the period between 8 and 9 o'clock is the twilight hour in the British islands at this season. The German submarine campaign is continuing actively. Dispatches from Norway state that the people of that country have been aroused by the sinking last week of the Norwegian steamer Minerva and the attempt to torpedo the Iris, which went to her assistance.
