So, too, with our mess. The dream here consisted of a jolly little parlour that was the envy of all the other company messes. As usual, the rooms led into one another, the kitchen into the parlour, the parlour into a bedroom; I might almost continue, and say the bedroom into a bed! For the four-poster, when curtained off, is a little room in itself. It was a good billet, but best of all was Madame herself. Suffice it to say she would not take a penny for use of crockery; and she would insist on us making full use of everything; she allowed all our cooking to be done in her kitchen; and on cold nights she would insist on our servants sitting in the kitchen, though that was her only sitting-room. Often have I come in about seven o’clock to find our dinner frizzling merrily on the fire under the supervision of Gray, the cook, while Madame sat humbly in the corner eating a frugal supper of bread and milk, before retiring to her little room upstairs. Ah, Madame! there are many who have done what you have done, but few, I think, more graciously. If we tried to thank her for some extra kindness, she had always the same reply “You are welcome, M. l’Officier. I have heard the guns, and the Germans passed through Amiens; if it were not for the English, where should we be to-day?” So we settled down for our “rest,” for long field days, lectures after tea, football matches, and week-ends; I wrote for my Field Service Regulations, and rubbed up my knowledge of outposts and visual training. But scarcely had I been a week at Montagne when off I went suddenly, on a Sunday morning, to the Third Army School. I had been told my name was down for it, a few days before, but I had forgotten all about it, when I received instructions to bicycle off with Sergeant Roberts; my kit and servant to follow in a limber. I had no idea what the “Third Army School” was, but with “note-book, pencil, and protractor” I cycled off at 11.0 a.m. “to fields and pastures new.” Most people, I imagine, have had the following experience. They have a great interest in some particular subject, yet they have somehow not got the key to it. They regret that they were never taught the elements of it at school; or it is some new science or interest that has arisen since their schooldays, such as flying or motoring. They are really ashamed of asking questions; and all books on the subject are technical and presuppose just that elementary knowledge that the interested amateur does not possess. Then suddenly he comes on a book with those delicious phrases in the preface promising “to avoid all technical details,” apologising for “what may seem almost childishly elementary,” and containing at the end an expert bibliography. These are the books written by very wise and very kind men, and because they are worth so much they usually cost least of all!
