In the winter of 1916 I was wounded. At the end of my spell in hospital I was reported unfit for further active service and appointed to a post in the contracts department of the Air Board. I was put in charge of chemicals, celluloid, rubber tubing, castor oil, linen and balloon fabrics. I spent my time haggling with German Jews over the price of chemicals and celluloid, with Greek brokers over the castor oil, with Ulstermen over the linen. Spectacled Japanese came to visit me with samples of crêpe de Chine which they tried to persuade me—and they offered choice cigars—would be both better and cheaper than cotton for the manufacture of balloons. Of every one of the letters I dictated first eleven, then seventeen, and finally, when the department had flowered to the height of its prosperity, twenty-two copies were made, to be noted and filed by the various sub-sections of the ministry concerned. The Hotel Cecil was filled with clerks. In basements two stories down beneath the surface of the ground, in attics above the level of the surrounding chimney-pots, hundreds of young women tapped away at typewriters. In a subterranean ball-room, that looked like the setting for Belshazzar’s feast, a thousand cheap lunches were daily consumed. In the hotel’s best bedrooms overlooking the Thames sat the professional civil servants of long standing with letters after their names, the big business men who were helping to win the war, the staff officers. A fleet of very large motor cars waited for them in the courtyard. Sometimes, when I entered the office of a morning, I used to imagine myself a visitor from Mars.... One morning—it was after I had been at the Air Board for several months—I found myself faced with a problem which could only be solved after consultation with an expert in the Naval Department. The naval people lived in the range of buildings on the opposite side of the courtyard from that in which our offices were housed. It was only after ten minutes of labyrinthine wanderings that I at last managed to find the man I was looking for. He was a genial fellow, I remember; asked me how I liked Bolo House (which was the nickname among the knowing of our precious Air Board office), gave me an East Indian cheroot and even offered whiskey and soda. After that we settled down to a technical chat about non-inflammable celluloid. I left him at last, much enlightened. “So long,” he called after me. “And if ever you want to know any mortal thing about acetone or any other kind of bloody dope, come to me and I’ll tell you.” “Thanks,” I said. “And if by any chance you should happen to want to know about Apollonius Rhodius, shall we say, or Chaucer, or the history of the three-pronged fork....” He roared very heartily. “I’ll come to you,” he concluded.
