As the miles unwind behind the regiment the character of the country begins to change. There are fewer women and children to be seen now; there are more roofless buildings, more house-fronts gaping doorless and windowless, more walls with ragged rents, and tumbled heaps of brick lying under the yawning black holes. But the grass is still green, and the trees thick with foliage, the fields neatly ploughed and tilled and cultivated, with here and there a staring notice planted on the edge of a field, where the long, straight drills are sprinkled with budding green—'Crops sown. Do not walk here.' Altogether there is little sign of the heavy hand of war upon the country, and such signs as there are remain unobtrusive and wrapped up in springing verdure and bloom and blossom. Even the trapping of war, the fighting machine itself, wears a holiday or—at most—an Easter-peace-manoeuvre appearance. A heavy battery has its guns so carefully concealed, so bowered in green, that it is only the presence of the lounging gunners and close, searching looks that reveal a few inches of muzzle peering out towards the hill crest in front. Scattered about behind the guns, covered with beautiful green turf, shadowed by growing trees, are the dwelling-places of the gunners, deep 'dug-outs,' with no visible sign of their existence except the square, black hole of the doorway. Out in the open a man sits with a pair of field-glasses, sweeping the sky. He is the aeroplane look-out, and at the first sign of a distant speck in the sky or the drone of an engine he blows shrilly on his whistle; every man dives to earth or under cover, and remains motionless until the whistle signals all clear again. An enemy aeroplane might drop to within pistol shot and search for an hour without finding a sign of the battery.

When the regiment swerves off the main road and moves down a winding side-track over open fields, past tree-encircled farms, and along by thick-leaved hedges, it passes more of these Jack-in-the-Green concealed batteries. All wear the same look of happy and indolent ease. Near one is a stream, and the gunners are bathing in an artificially made pool, plunging and splashing in showers of glistening drops. They are like school boys at a picnic. It seems utterly ridiculous to think that they are grim fighting men whose business in life for months past and for months to come is to kill and kill, and to be killed themselves if such is the fortune of war. Another battery of field artillery passes on the road. But even here, shorn of their concealing greenery, in all the bare working-and-ready-for-business apparel of 'marching order,' there is little to suggest real war. Drivers and gunners are spruce and neat and clean, the horses are sleek and well fed and groomed till their skins shine like satin in the sun, the harness is polished and speckless, bits and stirrup-irons and chains and all the scraps of steel and brass twinkle and wink in bright and shining splendour. The ropes of the traces—the last touch of pride in perfection this, surely—are scrubbed and whitened. The whole battery is as spick and span, as complete and immaculate, as if it were waiting to walk into the arena at the Naval and Military Tournament. Such scrupulous perfection on active service sounds perhaps unnecessary or even extravagant. But the teams, remember, have been for weeks past luxuriating in comfortable ease miles back in their 'wagon-line' billets, where the horses have done nothing for days on end but feed and grow fat, and the drivers nothing but clean up and look after their teams and harness. If the guns up in the firing line had to shift position it has meant no more to the teams than a break of the monotony for a day or two, a night or two's marching, and a return to the rear.

It is afternoon now, and the regiment is drawing near to the trenches. The slanting sun begins to throw long shadows from the poplars. The open fields are covered with tall grass and hay that moves in long, slow, undulating waves under the gentle breeze that is rising. The sloping light falling on them gives the waves an extraordinary resemblance to the lazy swell on a summer sea. Here and there the fields are splashed with broad bands of vivid colour—the blazing scarlet of poppies, the glowing cloth-of-gold of yellow mustard, the rich, deep, splendid blue of corn-flowers.

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.

A mile or two back from the firing line a couple of big motor-cars swing over the crest of a gentle rise, swoop down into the dip, and halt suddenly. A little group of men with scarlet staff-bands on their caps and tabs on their collars climb out of the cars and move off the track into the grass of the hollow. They prod sticks at the ground, stamp on it, dig a heel in, to test its hardness and dryness.

The General looks round. 'This is about as low-lying a spot as we have on this part of front,' he says to his Chief of Staff. 'If it is dry enough here it must be dry enough everywhere else.'

The Chief assents, and for a space the group stands looking round the sunlit fields and up at the clear sky. But their thoughts are not of the beauties of the peaceful landscape. The words of the General are the key to all their thoughts. For them the promise of spring is a grim and a sinister thing; to them the springy green turf carpet on the fields means ground fit to bear the weight of teams and guns, dry enough to give firm foothold to the ranks of infantry charging across the death-trap of the neutral ground, where clogging, wet, slippery mud adds to the minutes under the hail of fire and every minute there in the open means hundreds of lives lost. The hard, dry road underfoot means merely that roads are passable for heavy guns and transport. The thick green foliage of the trees is so much cover for guns and the moving of troops and transport under concealment from air observation; the clear, blue sky promises the continuance of fine weather, the final release from the inactivity of the trenches. To these men the 'Promise of Spring' is the promise of the crescendo of battle and slaughter.
