The description of the trenches forward of the subsidiary line is a far more formidable undertaking. We will commence with the right, as being the simplest and also, generally speaking, the most healthy. The subsidiary line was followed to the right almost as far as the cemetery. Just before reaching it a communication trench was found leading off (if you were lucky and knew the way) to the left under an overhead traverse, and guarded by a sentry. The latter in the early days informed you, in a bored fashion, that the wind was dangerous or the reverse, and criticized your box-respirator if not in the alert position. Following the trench in its windings for a short distance, Vancouver Avenue branched off to the left. This was only half finished, though you could with much floundering get through it to Gloucester Avenue; in reality, however, it was quite useless. A hundred yards or so farther on you suddenly came on a corrugated iron sentry-box, with a small weather-cock and a shell case suspended from a stick beside it, where the gas sentry over the right company Headquarters was stationed. Here in an open space you found two or three log huts of small dimensions, with one or two orthodox "bivvies." You then passed over a bridge, and, ducking your head to avoid a sheet of corrugated iron, under which cooking operations were usually going on, you entered a low edifice, which was lighted, it may be mentioned, with two small windows of real glass. Here you might find O.C. "D" Company sitting at the table, endeavouring to compose one of the innumerable reports that the higher powers delighted to collect. Two or three bunks adorned the walls; and a form on either side of the table, a Véry pistol, a tin of cigarettes, some recent pamphlets, and odd pieces of officers' equipment, made up the furniture. You could stand up more or less erect, and the place was really quite comfortable, but hardly shell-proof.
