he same
cannot be said of this operation carried out by a large number of
machines which can go to the same places and bomb continually.

"Besides the number of men that are actually killed in these
raids, great disturbance is caused in the enemy's communication
lines, thereby hindering the operations. For example, since the
British Admiralty has increased the number of its bombing
squadrons in northern France and has decided to attack constantly
the two harbours of Ostend and Zeebrugge and the locks, bridges,
and canals leading to them they have greatly interfered with the
activity of these two German bases.

"It is certain that shortly, owing to this, these two ports will
no more be used by German torpedo boats and submarines. What the
English Royal Naval Air Service has been able to accomplish with
100 machines the Flying Corps of the United States with 1000
machines must be able to carry out on other parts of the front.

"The work of the bombing machines is rendered difficult now by
the fact that the actual lines are far from Germany. But it is
hoped that soon fighting will be carried on near the enemy
frontier and then a wonderful field will be opened to the bombing
machines.

"All the big ammunition factories which are in the Rhine and Ruhr
valleys, like Krupp's, will be wonderful targets for the American
bombing machines. If these machines are of the proper type--that
is to say, sufficiently fast and well armed and able to carry a
great weight of bombs--nothing will prevent them from destroying
any of these important factories.

"As Germany at the present time is only able to continue the war
because of her great stock of war material the destruction of her
sources of production would be the end of her resistance. For
this also the Allies must turn to America. Such a large number of
machines is required to produce results that America must be
relied on to manufacture them.

"Every man in this country must know that it is in the power of
the United States, no matter what can be done in other fields, to
bring the war to an end simply by concentrating all its energies
on producing an enormous amount of material for aviation, and to
enlist a corresponding number of pilots. But this will not be
done without great effort. In
