is only at manœuvres. In close order they may still look alike, but let them be extended in rough country, and you will see that yours is the blade of steel; the particles of its metal are coherent; it will bend, but not break. The other is of wrought iron, polished on the surface but of brittle material, and sure to fly to pieces in any rough usage. By this file organisation you will produce in the men in the ranks the highest degree of cohesion—the habit of regulating their own actions in accordance with the actions and needs of others in furtherance of one general aim. Having secured this cohesion among the men, you have still to produce it within the company as between platoons and sections. For cohesion is the coping stone of the edifice of efficiency, and rests on a basis of discipline, moral and training. It makes possible the application of the principle of mutual support which is indispensable in the attack (F.S.R., 105 (4)), and it enables retirements and defensive action to be carried out without disorganisation, and with the minimum of loss. Whenever sections act together, see to it that the non-commissioned officers keep an eye on the movements of the others, and question them as to the extent their orders to their sections should be influenced by the needs and movements of the others. By this means they will be induced to check the inclination to play only for their own hands, and to remember always that their unit is part of a combination which can best attain success by acting accordingly. VIII. Training is the preparation of officers and men for the duties which they will carry out in war. These duties consist in the application of the principles contained in the training manuals, and it is your business to provide concrete examples. But in these days of long range arms combats take a very long time, and you cannot expect in a parade of perhaps one or at most two hours, and with a limited extent of ground, to carry out all the varied phases of an operation which, in warfare, would take anything from six to eighteen hours to complete, and would extend over perhaps five or six miles of country, even if we limit ourselves to the extreme ranges of heavy artillery, and take no account of movements not within the range of possible fire. Therefore, in your training, you must be analytical, choosing for one parade such phase or phases as you have time and ground for, and doing the others later on. When your company knows all it can be taught thus piecemeal, it will be early enough to try to get time and ground to perform continuous operations. * * * * *
