"What I would like to know," said Frank Chadwick, "is just how long England intends to put up with the activities of the German submarines in the waters surrounding the British Isles." "How long?" echoed Jack Templeton. "Surely you know that England is already conducting a vigorous campaign against them." "I don't seem to have heard anything of such a campaign," returned Frank dryly; "but another big liner was torpedoed and sunk off the coast of Ireland yesterday. What are we going to do about it? That's what I want to know."
