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.
The results of the last year have shown the ability of our seamen to get
upon terms with the submarine menace and gradually to gain the upper
hand. This has been achieved in spite of an imperfect knowledge of a new
and barbarous method of warfare and of a scarcity of suitable material.
Our material resources for this warfare are already improved and are
being rapidly augmented, while science is placing at our disposal means
of offense and defense of which we have been in need.

With regard to the other factor, a rapid and continuous increase in the
output of merchant tonnage will inevitably follow the united efforts of
all engaged in merchant shipbuilding in this country. * * * During the
critical period that confronts us we must rely to a large extent on our
own shipyards and on ourselves. Our partners in the war are making every
effort to increase their production of ships, but a considerable time
must elapse before the desired output is secured.

To produce in the United Kingdom 1,800,000 tons in 1918, and to reach an
ultimate production at the rate of 3,000,000 tons per annum, is well
within the present and prospective capacity of our shipyards and our
marine engineering shops. But the ranks of the skilled men must be
enlarged without delay by the introduction of men and women at present
unskilled. The education of these newcomers, upgrading, and
interchangeability of work are essential, and must be pressed on with
the good-will of employers, foremen, and men.
It is to insure the vigorous co-operation of all concerned that the
Admiralty has recommended the publication of the facts.
