Fifty yards ahead was a zigzag trench, its direction only discernible by interrupted sections of sand-bags and badly-shattered wire. Subjected earlier in the day to a terrible artillery pounding, it had been abandoned, but whether by Briton or Hun there was no indication except by closer examination. Evidently it was the rearmost of an intricate system of field-fortifications, for Malcolm was on the parados side while beyond, merging into smoke and haze, were other ramifications of the maze of trenches, all silent and deserted.
