As a machine gunner I was particularly interested in the construction of the machine-gun emplacements. The covered battle positions were very solidly built. The roofs were supported with immense logs or steel girders covered over with many layers of sandbags. There were two carefully concealed loopholes looking out to a flank, but none for frontal fire, as this dangerous little weapon best enjoys catching troops in enfilade owing to the rapidity and the narrow cone of its fire. Its own front is protected by the guns on its right and left. At each emplacement there was a range chart giving the ranges to all parts of the enemy's trenches, and to every prominent object both in front of and behind them, within its field of fire. When not in use the gun was kept mounted and ready for action in the battle position. "But remember this," said Shorty, "you never fires from your battle position except in case of attack. W'en you goes out at night to 'ave a little go at Fritzie, you always tykes yer gun sommers else. If you don't, you'll 'ave Minnie an' Busy Bertha an' all the rest o' the Krupp childern comin' over to see w'ere you live." This was a wise precaution, as we were soon to learn from experience. Machine guns are objects of special interest to the artillery, and the locality from which they are fired becomes very unhealthy for some little time thereafter. V--AT THE "MUD LARKS'" BEAUTY SHOP We stopped for a moment at "The Mud Larks' Hair-dressing Parlor," a very important institution if one might judge by its patronage. It was housed in a recess in the wall of the traveling trench, and was open to the sky. There I saw the latest fashion in "oversea" hair cuts. The victims sat on a ration box while the barber mowed great swaths through tangled thatch with a pair of close-cutting clippers. But instead of making a complete job of it, a thick fringe of hair which resembled a misplaced scalping tuft was left for decorative purposes, just above the forehead. The effect was so grotesque that I had to invent an excuse for laughing. It was a lame one, I fear, for Shorty looked at me warningly. When we had gone on a little way he said:-- "Ain't it a proper beauty parlor? But you got to be careful about larfin'. Some o' the blokes thinks that 'edge-row is a regular ornament." I had supposed that a daily shave was out of the question on the firing-line; but the British Tommy is nothing if not resourceful. Although water is scarce and fuel even more so, the self-respecting soldier easily surmounts difficulties, and the Gloucesters were all nice in matters pertaining to the toilet. Instead of draining their canteens of tea, they saved a few drops for shaving purposes.
