This airman is a well-known character among the troops in Flanders, known to all as "the mad major." His evening recreation consists in flying but a few hundred feet above the enemy's trenches, and raking them with his machine-gun to show his absolute contempt for their marksmanship. I have seen them in impotent fury fire at him every missile they had, including "pine-apples" and "minnies"; but he bears a charmed life, for, though he returned and repeated his performance four times for our benefit, he did not receive a scratch. I went over the German lines with him for instruction in aerial observation. He said to me: "Do you see that battery down there?" I replied "No!" His next remark was, "I'll take you down," and he shot down about five hundred feet nearer. We were getting pasted by "archies" much more than was pleasant, so when he next shut off his engine, to speak to me, I did not wait for his question but assured him that I could see the German battery quite plainly. I hope the recording angel will take into account the extenuating circumstances of that lie. We had a "spring gun" or "catapult" that came very near preventing this book ever being written. On one occasion we placed a bomb in the cup, but instead of taking the spring and lever out, which was the correct way, we tried a new experiment of holding the lever down with two nails which would release the spring as soon as it was let off. Unfortunately, the bomb rolled off at our feet, and we had four seconds to get to a safe distance. Some of us got bad bruises on our foreheads as we dived for an open dugout as though we ourselves had been thrown from a catapult. On another occasion we used Mills grenades with a grooved base plug. To our alarm, the first one exploded with a beautiful shrapnel effect just above our heads. I am sure a piece passed through my hair but I could not wear a gold braid for a wound because, not even with a candle, could the doctor find a mark.
