(4) The effect, method, and proportionate value of rifle fire and of the bayonet.

(5) The use of field artillery; and particularly whether, after a certain degree of rapidity, still greater rapidity of fire was worth having.

(6) The exact rôle that would be played in modern war by the supply of certain materials hitherto unimportant and discoverable only in certain limited regions, most of them out of Europe. There are a great number of these materials, but much the most important is petrol.

(3) Whether mobilization would work smoothly or not in the face of class struggles supposedly formidable to national interests.

(4) The action of our modern town populations under the moral strain of war.
