In this connexion we note an interesting letter from Mr.

A. H. Pollen, the well-known naval expert, who writes to the Manchester Guardian that " the way to make others give up submarines is to give them up our: selves." We quite agree. Even from the technical point of view the danger from hostile submarines can be greatly exaggerated. The methods of dealing with them are now known. Political considerations are really more important, and as Mr. Pollen truly says, there is only one way of convincing Americans, and that is to set an example. It is most encouraging to find an expert like Mr. Pollen, who has studied the Navy and been proud of it all his life, sharing our opinion that safety is only to be won by those—the statesmen—who will daringly take what are called " risks."
