Alternative positions in the same hedgerow should be avoided, as it is certain to be discovered immediately, and the range is probably already known.

The edge of the wood, if it commands suitable ground, is an excellent position for machine guns; but if the carriages remain in the wood they must be provided with cover. When time and material are available, a good field of fire may be obtained by erecting a platform ten to twelve feet above the ground in the trees, and placing a machine gun on this; not only is the field of fire much increased, but the gun will be
