It would be a good thing if one could regard the works when once carried through as definitely finished; but that would be too much to hope for, since the most solid revetments crumble in sorry fashion under bombardment, and the elements also seem to be bent on destroying them. Anything heavy settles little by little, owing to the lack of consistency in the subsoil. In bad weather especially, when the rain never ceases and the floods spread, our men daily report parapets giving way and duckboards disappearing under the water or mud. Then everything has to be done over again. One must set to work, with a patience ever sorely tried, to reconstruct laboriously what was originally put together only by the most strenuous efforts. Thus it has come about that many of the trenches have had to be reformed _five or six times_. So far we have dealt only with the main positions. We turn now to the prodigious effort demanded by the construction of advanced fortifications right in the middle of the floods. The first step is to make foot-bridges, several kilometres long in some places. (One of our photographs gives a striking view of such a bridge.) Over these, which the enemy can sweep with his fire, all the materials needed for making the advanced works must be carried, usually on men's backs and in any case by very precarious means of transport. A mere "water-post" requires thousands of sand-bags, so you can form some idea of the labour implied in the building of one of the many important posts situated in the inundated area to protect our main positions. All the earthworks, reckoned in hundreds of cubic yards; all the concrete emplacements which alone are able to withstand the continual bombardment; all the close networks of barbed wire have had to materialise but a few yards away from the enemy's lines. You may well ask yourself whence the men have drawn the reserves of perseverance, energy and pluck that were needed in such conditions for raising fortifications like these above the waters. (_c_) _Various Engineering Works._ Most of the works already referred to were carried out either entirely or chiefly by the infantry, who, after hours of guard duty in the trenches, laid aside the rifle only to pick up a tool and indefatigably continue their rough and dangerous labour among the same scenes of ruin and devastation.
