You take the chit from him languidly, wondering whether you have earned a court-martial by omitting to report on the trench sleeping-suits which someone in the Rearward Services has omitted to forward, and you read, still languidly at first; then you get up and whoop, throw your primus stove into the air and proceed to dance on the parapet, if your trench has one. Then you settle down and read your message again to see if it still runs, "You are detailed to attend three months' Staff work course at Boulogne, commencing to-morrow. A car will be at the dump for you to-night. A month's leave on completion, of course." But all courses are not like this; all you can say is that some are less unlike it than others. I was sitting in a warm billet about twelve noon having breakfast on the first day out of trenches when the blow fell on me. I was to report about two days ago at a School of Instruction some two hundred yards away. I gathered that the course had started without me. I set some leisurely inquiries in train, in the hope that it might be over before I joined up. I also asked the Adjutant whether I couldn't have it put off till next time in trenches, or have it debited to me as half a machine-gun course payable on demand, or exchange it for a guinea-pig or a canary, or do anything consistent with the honour of an officer to stave it off. For to tell the truth, like all people who know nothing and have known it for a long time, I cherish a deeply-rooted objection to being instructed. Unfortunately the Adjutant is one of those weak fellows who always tell you that they are mere machines in the grip of the powers that change great nations. So on the third day I bought a nice new slate and satchel and joined up. Even now, after some days of intense instruction, I find my condition is a little confused and foggy. Of course it covers practically the whole field of military interests, and I ought to be able to win the War in about three-quarters of an hour, given a reasonable modicum of men, guns, indents, physical training and bayonet exercise, knowledge of military law, and acquaintance with the approved methods of conducting a casualty clearing station, a mechanical transport column, and a field kitchen. The confusion of mind evident in this last sentence is a high testimonial to the comprehensive nature of our course. Physical training made the strongest appeal to me. I remember some of the best words, not perhaps as they are, but as I caught them from an almost over-glib expert. Did you know you had a strabismal vertebra? or, given a strabismal vertebra, that it could be developed to almost any extent by simply 'eaving from the 'ips? Take my tip and try it next time you're under shell-fire.
