“The Americans, too, have understood this. They propose to build a thousand wooden vessels of 3,000 tons. But before these can be brought into action they will, I confidently hope, have nothing left to save.
“I base this confidence upon the indications which are visible, despite the English policy of suppression and concealment.
“Take the total British trade. The figures for March are still not yet available, but those for February tell us enough.
“British imports amounted in January of this year to 90 million pounds sterling, in February to only 70 million; the exports have gone down from 46 to 37 millions sterling—imports and exports together showing a decline of over 20 per cent. in the first month of the submarine warfare. And again, the rise in prices all round has, since the commencement of the U-boat war, continued at a more rapid rate, so that the decline in the import quantity from one month to another may fairly be estimated at 25 per cent. The figures for imports and exports, then, confirm my supposition as to the decrease of tonnage in the traffic with British ports.
“The British Government has endeavoured, by the strictest measures rigorously prohibiting import of less important articles, to ward off the decline in the quantity of vital necessaries imported. The attempt can only partially succeed.
