To-day, the ability for aviation to carry increasing weight furnishes a new
method for abundantly spreading poison gases with the aid of stronger and
stronger bombs, and to reach armies, the centres of population in the rear,
or to render regions uninhabitable.

Chemical warfare is therefore in a condition to produce more formidable
results over more extended areas.

It is incontestable on the other hand that this growth will find an easy
realisation in one country, Germany, addicted in times of peace,
to wholesale manufacture of chemical products, which a simple modification
in reactions can transform into war products.

This country, deprived, partially at least, of its former methods of fighting,
and its numerous forces of specially trained soldiers, regularly organised
and strongly armed, will be more drawn toward the new systems of attack--
that of chemical warfare.

Chemical warfare must therefore enter into our future provisions
and preparations, if we do not wish to experience some terrible surprises.

The work of Major Lefebure gives an exact idea of the possibilities he finds
to-day in Germany, and through them the dangers with which she threatens us.
In this form it constitutes a warning; and information of the highest order,
for the minds who remain anxious for the fate of their country confronted
by the inefficience of the old fighting methods which the progress of industry
out of date renders daily.

By sounding the alarm in both our countries, I find myself in company
with my faithful friend Field Marshal Sir Henry Wilson. This is an
