I do not think I am divulging information which should not be made public when I say that the output of guns and ammunition of all calibres in 1917 is not far short of twice the output in 1916. I need not remind the House of the special effort being made in the output of airplanes. These, I understand, are nearly two and a half times the output of 1916, and arrangements for labor and material to secure a still greater output this year were in progress during the later months of 1917. We have been able to accomplish what I think must be admitted as an enormous development in the shipbuilding industry. We have reached in 1917 a total warship and merchant tonnage output practically equal to the biggest shipbuilding year this country has ever known. We have multiplied by ten the number of naval craft repaired and refitted, and in six months we have increased the merchant ship repaired tonnage by 80 per cent.--an increase of 237,000 tons per week. I would ask the House to notice this fact, that, notwithstanding all these great extensions of work in many directions, and notwithstanding all these great extensions of power of the country, we ended 1917 with an output of new merchant tonnage of 420,000 for the last quarter, against 213,000 for the last quarter of 1916. That was done, moreover, with a dislocated industry, with yards only gradually being cleared of unfinished work, and with large numbers of unskilled personnel in the yards. Admiralty Summary of Shipping Losses Record of Three Years _The British Board of Admiralty, with the sanction of the War Cabinet and the concurrence of the Allies, on March 21 published a memorandum revealing the world's total shipping losses from the beginning of the war to Jan. 1, 1918. The essential portions are as follows:_ In the Spring of 1917 the full menace of the submarine campaign was first disclosed. Since that date we have steadily increased our knowledge and our material resources for this novel warfare. Three statements are attached, showing for the United Kingdom and for the world, for the period August, 1914, to December, 1917: 1. Losses by enemy action and marine risk. 2. Mercantile shipbuilding output. 3. Enemy vessels captured and brought into service. Diagrams showing in graphic form the losses and shipbuilding output for the United Kingdom and for the world are also attached. The situation should be viewed from the standpoint of the world's tonnage, as in these problems the mercantile navies of the whole world, excluding the enemy, may be regarded as one. It will be noticed that the diagrams record facts, and that nothing has been included in the nature of an estimate.
