belonging to an English firm, stood Von Kluck's house, alleged to have been once the Headquarters of that famous General, and now used as the A.D.S., which for many months escaped a direct hit, while neighbouring houses were all but obliterated. A strip of open country followed; on the left, a wilderness of ruins and marshland, with a glimpse of 18-pounders cleverly concealed; on the right, loop-holed screening with a considerable view of the country beyond. Nouvel Houplines (often thought to be Houplines itself, which was close to the river) consisted of two main streets forming an acute angle. At the junction stood Tissage Dump, where R.E. material for the line was stored. In the adjoining houses were a pioneer workshop, an observation post, the canteen, and the regimental aid post. The trench tram line (a continuation of the ordinary tram line from Armentières) divided here, one line running up alongside Gloucester Avenue to the trenches, the other following round to Durham Castle and other dumps. Several tall factory chimneys were grouped about this spot, all used as observation posts, and rejoicing in colonial names difficult to pronounce. Most of them bore signs of shell fire, one having been pierced right through close to its base, another having a large piece taken right out of its side. The entrance to Gloucester Avenue--or "Gloster Ave," as the signboard called it--was really very picturesque, the trench descending gradually below ground level through what had once been a garden. On either side was abundant foliage, which later became prettily covered with flowers and presented a picture that might well have been the setting for the opening scene of "The Arcadians." We began our walk up Gloucester Avenue, noting the trench running off to Spain Avenue, another fine communication trench. The way was up a gradual incline. At the top a network of narrow trenches appeared, and through these we made our way into the subsidiary line to Battalion Headquarters, a group of "bivvies" and short trenches entered under a small overhead traverse. On the immediate left stood a small elephant back, which combined the dual functions of mess and Adjutant's office, and opposite this was the cook-house. To the left was a double concrete dug-out, where "Signals" dwelt, and up a little short trench a minute concrete "bivvy" for the Commanding Officer. In the mess we found the Commanding Officer of the 38th Battalion A.I.F. awaiting us, and he explained that our present place of rest was the old right Battalion Headquarters, while the left was in more commodious but less conveniently situated quarters in the spacious cellars of Cambridge House, some way along the subsidiary line. Half the Australians' Headquarters lived in one place and half in the other, and, though the two were connected by telephone, the disadvantages of the separation were obvious.
