ANTI-SUBMARINE METHODS.

GROUND GAINED BY ALLIES

NEED FOR GREATER EFFORTS A. and N.Z. NEW YORK, July 1.

Mr, Charles Grasty, London correspondent of the New York Times, interviewed Admiral Sims, commander of the American fleet in European waters, who said: "The presence of submarines on our coast will not affect the outcome of the war. A year ago allied tonnage was decreasing, and the Central Powers were winning the war. Now the situation is reversed. Allied tonnage is increasing, and the number and efficiency of the submarines is decreasing. There are between four and five thousand anti-sub-marine vessels of all types, all operating with effect. The best' means of combating the submarines is convoying, depth charging, and the device by which surface vessels are able to follow submerged submarines by the sound of their engines. Experience shows that Germany has been able to keep about 10 per cent, of its undersea fleet actively engaged, which is equivalent to between 15 and- 20 submarines. This number has now been greatly reduced, but the allies still had not enough anti-submarine vessels, and must buik more all the time.
