Submarine warfare against passenger vessels goes on. in spite of
the German promises to America. The Austrian, flag is sometimes flown on submarines which are believed to be,German ; and if Austria should be pinned to a pledge of abstention by- Amerioa, we suppose that Turkish and Bulgarian submarines would suddenly appear. On Tuesday of last week the Japanese passenger steamer Yasaka Meru,' of eleven thousand tons, was sunk without warning. Fortunately all the passengers and crew were picked- op by a French gunboat and were landed at Port Said. The passengeri numbered one hundred and twenty, and only one was an American. A much more disastrous affair was the sinking of the French passenger steamer Ville de la Ciotat ' on Friday week, also in the Mediterranean. She was torpedoed. without warning by a German submarine. Eighty of the passengers and crew were lost. We have not heard that there were any Americans among them.
