For one or two miles past the track has been plainly marked by sign-posts bearing directions to the various trenches and their entrances. Now, at a parting of the main track, a group of 'guides'--men from the regiment being relieved from the trenches--wait the incoming regiment. Company by company, platoon by platoon, the regiment moves off to the appointed places, and by company and platoon the outcoming regiment gathers up its belongings and moves out. In most parts of the firing line these changes would only be made after dark. But this section bears the reputation of being a 'peaceful' one, the Germans opposite of being 'tame,' so the reliefs are made in daytime, more or less in safety. There has been no serious fighting here for months. Constant sniping and bickering between the forward firing trenches has, of course, always gone on, but there has been no attack one way or the other, little shell-fire, and few aeroplanes over. The companies that 'take over' the support trenches get varied instructions and advice about tending the plants and flowers round the dugouts, and watering the mustard-and-cress box. They absorb the advice, strip their accoutrements and tunics, roll up their shirt-sleeves, and open the throats, fish out soap and towels from their packs, and proceed to the pump to lather and wash copiously. The companies for the forward trench march down interminable communication trenches, distribute themselves along the parapet, and also absorb advice from the outgoing tenants--advice of the positions of enemy snipers, the hours when activity and when peace may be expected, the specially 'unhealthy' spots where a sniper's bullet or a bomb must be watched for, the angles and loopholes that give the best look-out. The trenches are deep and well-made, the parapets solidly constructed. For four days or six, or as many as the regiment remains 'in,' the range of the men's vision will be the walls of the trench, the piled sandbags, the inside of their dug-outs, and a view (taken in peeps through a loophole or reflected in a periscope mirror) of about fifty to a hundred yards of 'neutral ground' and the German parapet beyond. The neutral ground is covered with a jungle of coarse grass, edged on both sides with a tangle of barbed wire. Close to the German parapet are a few black, huddled heaps--dead Germans, shot down while out in a working party on the wire at night, and left there to rot, and some killed in their own trench, and tumbled out over the parapet by their own comrades. The drowsy silence is broken at long intervals by a rifle shot; a lark pours out a stream of joyful thrilling song. * * * * *
