As I went along with that tower of strength, the company sergeant-major, followed by an orderly carrying two rum jars produced from under my bed, I discussed the subject of working-parties for the night, and other such dull details of routine. Also we discussed leave. His dug-out was at the corner of Old Kent Road and Park Lane, and there I found the “Quarter” (Company Sergeant-Major Roberts) waiting with the five dixies of hot tea, just brought up on the ration trolley from the Citadel. Sergeant Roberts saluted, and informed me that all was correct. Then the sergeant-major spilled the contents of the two jars into the five dixies, and as he did so the ten orderlies, two from each platoon, and two Lewis gunners, made off with the dixies. Then I made off, but followed by Sergeant Roberts with several papers to sign, and five pay books in which entries had to be made for men going on leave. One signed the pay-book, and also a paper to the quartermaster authorising him to pay 125 francs (the usual sum) to the undermentioned men, out of the company balance which was deposited with him on leaving billets. I signed everything Sergeant Roberts put before me, almost without question. “Well, Clark,” I said, as we sat down to a tea of hot buttered toast, jam and cake. “How goes it?” “I’ve just been down a mine-shaft with that R.E. officer, I forget his name--the fellow with the glasses.” “I know,” I replied; “I don’t know his name either, but it doesn’t matter. Did you go right down, and along the galleries? How frightfully interesting. I always mean to go, but somehow don’t. Well, what about it?” “By Jove,” said Clark. “It’s wonderful. It’s all as white as snow, dazzling white. I never realised that before, although you see these R.E.’s coming out all covered with white chalk-dust. First of all you go down three or four ladders; it’s awfully tricky work at the sort of halts on the way down, because there’s a little platform, and very often the ladder goes down a different side of the shaft after one of these halts; and if you don’t notice, you lower your foot to go on down the same side as you were going before, and there’s nothing there. The first time I did this and looked down and saw a dim light miles below, it quite gave me a turn. It’s a terrible long way down, and of course you go alone; the R.E. officer went first, and got ahead of me.” “Have some more tea, and go on.” “Well, down there it’s fearfully interesting. I didn’t go far up the gallery where they’re working, because you can’t easily pass along; but the R.E. officer took me along a gallery that is not being worked, and there, all alone, at the end of it was a man sitting. He was simply sitting, listening. Then I listened through his stethoscope thing ...” “I know,” I interposed. It is an instrument like a doctor’s stethoscope, and by it you can hear underground sounds a hundred yards away as clearly as if they were five yards off.
