Just a line to wish you the best of luck in the Matric, and to express the hope that you will do really well. Put in all the work you can right up to within twenty-four hours of the start of the exam. and then take one day right off duty altogether. I am certain you will do us all infinite credit. As to the Pater's remark that my recent letters have lacked detail, this is mainly due to the Censorship regulations, which I personally like to observe in the spirit as well as in the letter. Besides, a careless remark may be misconstrued, and it is difficult to say one thing without disclosing others that ought not to be revealed. Then there is the other consideration, that if I write fully you may perhaps get the "wind up" about my personal safety. As regards photographs of myself, the regulations as to the possession of cameras are very stringent, and I really haven't the time or the inclination to go and get snapped by a civilian photographer out here. Again, _entre nous_, I regard photographs as trivialities--above all, those abominations "photos from the Front." A man who is really at the Front has neither time nor occasion to have photographs taken. No, if we must worry, let us worry first about the things that _do_ matter. I am frightfully sorry about the death of Felix Cohn. He was very cheerful when I saw him. We met twice in a certain large town which has of late figured prominently in the communiques. Our talk was of Dulwich, the cases of Roederwald and Gropius, of Wagner and music; and, of course, of the War itself. He had then been "over the top" once, on the same day that I was. Felix said that he had had an easy time, as his lot took about seven lines of trenches in an hour. He had done considerable work as a translator of German documents and in the examination of captured Germans. I feel sincere sympathy for Mr. Cohn, but there is little use in words of condolence in the case of such tragedies. It is the price of the game. To a large extent, the Pater's deductions about the work in Tanks on hot days are correct. Still, you can wear practically what you like when on duty, so one works in a shirt, shorts, puttees and boots. Although we are for the time being out of the battle line, I am really very busy; there is no slacking in the H.B.M.G.C.; but I am enjoying life hugely.
