We enter the salvage dump—an empty front room littered with all kinds of implements, and ask for the apparently necessary gas-mask and helmet, which are carefully dusted by a whistling sergeant. Carrying these helmets in one hand and the masks slung over our necks, we proceed towards the front. Now here for one moment we realise that we really are near a real war, for round the corner walk a couple of nonchalant Tommies carrying a stretcher, covered with a blanket, from beneath which protrude two heavy boots, toes towards the ground.

We hurry on and turn to the left and come out into the open, across which we move erratically, for, at the whistle of each shell, we sit in a crater until the noise of its explosion encourages us to proceed.

"I feel sure we should not be out here!" says my friend. I feel inclined to agree with him.

We reach a bank in which soldiers are hiding like rabbits in a warren. In little square holes the stolid, cheerful-looking men sit; here one smokes, there one cooks bacon, in another place one reads. Outside some of the cave doors a pair of socks or a shirt hangs out to dry. The existence seems to them the normal one, and returning to the life of the remote past they seem to have found a rough contentment.

At last we enter a trench and wander along it for five or six minutes, till through a turning on the left we see a narrow ditch leading to a wide muddy canal. We turn down this side trench and walk to the side of the water, over which is slung a narrow suspension-bridge about four feet wide, made of boards laid side by side.

We walk across this, and half-way over to the other side we meet an officer, and ask where the front is.

He laughs, and inquires who we are, and offers to take us to the mess, and suggests that we should wear the shrapnel helmet instead of our soft naval caps. We cross the bridge and walk down another trench to a farmhouse, covered with little white boards with D.A.Q.M.G.'s and D.A.D.O.'s, and other incomprehensible mysteries of staff hieroglyphics. I do not know quite what I have expected a staff mess to be like, but I know when I descend a damp ladder to a dim cellar lit by candles, and see a cheerful crowd of officers eating bread and butter and tea at a broken-down table, I am very surprised. I realise rapidly that a sub-lieutenant in the Air Service has a better time of it, as far as mere material comfort goes, than a colonel on his Majesty's staff.

"Found these two lads crossing the bridge with their shrapnel helmets swinging from their hands; may I introduce you to Major Smith and Captain So-and-so...." We are introduced all round and are given tea. No one questions our right to be there at all. Our story of being curious airmen from Dunkerque is believed. They are amused to hear of our big shell experiences. They have heard the shells passing overhead like express trains, although we had no indication of their approach at all. After we have received some friendly blame for keeping them awake at night with our engines when we pass over the Nieuport floods, the colonel who met us details an officer to take us to an observation post. We move down more trenches—Nose Alley, Nasal Avenue, Nostril Road, and others—till we reach a little broken-down building, inside which we penetrate through a small door. A pair of rickety staircases lead us up to a loft where an officer and a sergeant gaze through a narrow slit towards the east. On the ledge before them lies a map. They are keeping a particular sector of German trench under constant observation for the benefit of their own particular battalion.

Taking a pair of binoculars, I look and see the three British barricades of sandbags, for the ground here is too wet to permit of the digging of trenches. Men are seen sitting down or walking up and down behind these breastworks, and beyond can be seen the spiky curls and haphazard pegs of the barbed-wire entanglements. In the centre, a grey huddle of stone indicates the site of Lombartsyde Church. Now and again a cloud of smoke from a shell rises up behind the German trench. On the left are the sand-dunes on which the tall, red, broken houses of Westende stand desolate and fantastically suburban against the sky. I can see through the glasses the great painted advertisements on them, and notice here and there the missing roof, the shattered wall; but on the whole, save for the blank square of the glassless windows, they look untouched enough. It seems strange to think that the bare lifeless buildings of that watering town are full of an unseen life, that up in those roofs Germans are watching us only a few hundred yards away, as we are watching them. It is strange and uncanny. This, then, is the line—bleak, dead, full of a sense of ever-menacing danger, haunted by the hovering phantom of Death. We take a last look and start back to the car. The farther we go, the easier grows my heart. When at last we turn the corner of the town and see the old grey tender with its driver smoking beside it, I want to hail it as a welcome friend. Gladly we hear its engine throb—gladly we feel the thrill of movement—gladly we move down the eerie desolate road, by the canvas screens, the broken trees, where sounds the wail and bang of the shells, like doors in a great frightening empty house being shut and shut by some unseen and terrifying phantom hand.

Swiftly we leave the desolate loneliness of war behind, and welcome is the thought of the trim camp at the aerodrome with its flower-decked mess and fire-lit cabins. When at last we sweep across the little white bridge over the canal and stop beside the lawns of the quarter-deck, over which flaps the White Ensign, I realise keenly the comfort and the tranquillity of my life.
