"Open your mails? Yes, I'm afraid we do. And we find a good lot inside them! Do you know, there is a great warehouse in London filled from top to bottom with rubber, and nickel, and other commodities for which the Hun longs, disguised as all sorts of things--rubber fruit, for instance--taken from the most innocent-looking parcels--all dispatched from the United States to neutral countries in touch with Germany? But we are most punctilious about it all. Every single article retains its original address-label, and will be forwarded direct to its proper consignee, directly the war is over. Can you beat that? "Would we welcome Intervention? My dear sir, is it likely? Supposing _you_ had been caught entirely unprepared, and had been sticking your toes in for two years--fighting for time and playing a poor hand pretty well--and were at last ready to hit back, and hit back, until you had rendered your opponent incapable of further outrage, and were in a fair way to fix this war so that it never could happen again--would you welcome Mediation, or offers of Mediation? I think not. "Submarines? We aren't attaching _too_ much importance to submarine frightfulness. It is true we have lost a number of merchant ships, and that a number of innocent lives have been sacrificed. But let us put our hearts in the background for the present and look at the matter from the economic and military point of view. We have lost, in twenty-seven months, about one tenth of our original merchant fleet. Against that you have to set the fact that we have been steadily building new merchant ships during the same period. The dead loss of merchandise involved amounts to about one half per cent. of the total value--ten shillings in every hundred pounds; or fifty cents per hundred dollars. That won't starve us into submission. "But the Germans will build more and more submarines? Very probably. Still, I think we can leave it to the British and French navies to prevent undue exuberance in that direction. Our sailors have not been exactly garrulous during this war, but I think we may take it that they have not been entirely idle. Has it ever occurred to you that although there are hundreds of Allied warships patrolling the ocean to-day, you hardly ever hear of one being torpedoed by a submarine? Passenger ships and freight ships suffer to the extent I have quoted, but not the warships. Why is that? Don't ask me: ask Jellicoe! But it rather looks as if the submarine, as an instrument of naval warfare--as opposed to a baby-killing machine--had rather failed to deliver the goods.
