units and the combined action of all arms; good ground for early instruction is that whose features, from their nature and distance from each other, lend themselves to illustrate conditions under which the power of each unit and arm may be most profitably employed in conjunction with others. Troops trained over ground that gives the above advantages will acquire an eye for country. A knowledge of the uses to be made of ground will be common to all ranks, so that when they find themselves fighting on bad ground, which does not give much cover or good fire positions, they will be the more apt to search for such cover and fire positions as are obtainable, while troops trained on flat and open ground would be much slower in making the best of a bad job. We are not concerned with anything more than a company; therefore, get for your own use, if you can manage it—failing help from higher powers—a bit of ground of some sort, golf course, common, city park, or what not. It need not be very extensive. Even if it gives only three or four positions suitable for occupation by a section working in conjunction with another, say, six hundred by three hundred yards, it will give room for useful instruction; but, of course, a larger extent is preferable, as giving room for more extended and varied exercises. If your training ground is of limited extent, it should, nevertheless, if possible, have a wide field of view on all sides beyond its own confines, and leave you the right to send a few men to take positions on the adjoining country, even if not allowed to manœuvre about it, so that when carrying out your exercises you may be able to use men with blank cartridge to act as a skeleton enemy, when such is needed. But if you are not allowed to send men on to the neighbouring ground, the wide field of view will still enable you to indicate certain distant positions as _supposed_ to be held by the enemy. By this means you will be able to use the whole area of your permissible ground to represent a bit of the battlefield, and escape having to place the supposed enemy absurdly close to your manœuvring troops, e.g., at the edge of the training ground, or in some other position which makes heavy calls on the imagination. Britishers are not imaginative. Lastly, if all else fails, and you have nowhere to go except the flat parade ground, or even the drill hall, which in large towns is often very spacious, do not, I beg you, become discouraged and throw up all effort to get your men ready for field work. Do the exercises on the flat, limiting the extent of movements, if there is little room, and use flags or anything else to represent fire positions for sections and platoons, and let the men kneel or lie down between advances, if there is no cover. A great deal may be done in this way to lay a good foundation for extended order work. Your men will know the mechanism of it, and you will save much time when you do manage to have them out on a proper training ground.
