“I have no idea how close we passed to each-other. My impression of the moment was that the distance was inside of fifty yards, though it was doubtless really much greater. We were not, of course, going in exactly opposite directions, for the shell must have been coming down at a considerably greater angle than that at which we were going up. Yet the ‘aerial surf’ stirred up by the passage of the Hun’s little messenger of goodwill in that smooth stretch of atmosphere was heavy and persistent enough to keep my machine wallowing for over a mile.

“The air was going by us in a swift, steady river as we neared the German lines, and I never recall having been able to climb so quickly and easily. Lucky it was, too, for the enemy—probably in anticipation of a pursuit of their returning raiders—had their whole trench ‘hinterland’ planted with anti-aircraft guns, both stationary and movable. There was one little strip that blossomed out like a poppy garden as they opened up on us, and for a minute or so the smoke from the spreading shell-bursts formed a good-sized little cloud of its own. But they never had any real chance of getting us. My good little engine, singing like the wind in the telephone wires, had enabled me to get up over fourteen thousand feet without turning a hair and at that height you’re a lot safer from shells in an aeroplane than from taxis in crossing the Strand. K—— was feeling the altitude a bit, I think; I saw him wiping blood from his nose and pressing his hands to his ears, but he gave no signs of real distress. As for myself, beyond a little swelling of the fingers and a drumming at the temples, I was quite as usual.

“We passed over the main ‘bouquets’ of the ‘Archies’ without even feeling the kick of the shells bursting beneath us; but in dropping down to ten thousand feet a few miles beyond, we encountered an unexpected ‘plant’ of them and the shrapnel bullets were flying all about us for a minute or two. A score of neat little holes winked out in the wings, and one friendly bit of a bullet—spent, but still hot from its sharp flight—dropped gently into my lap and slightly singed the fold of my coat in which it found lodgment. Then we left that mare’s nest behind and the going grew smoother once more.

“It was only a few minutes later, and before any beginning had been made on the work we had come for, that K—— picked up a Zepp through his glass and began reporting its progress to me over the telephone. At first it was flying very high, doubtless to keep above gun-fire in crossing our lines. Once over, however, it came down rapidly, probably, as K—— suggested, with the purpose of luring the pursuing aeroplanes into easy range of the German ‘Archies.’ If that was the plan, it was eminently successful; for K—— presently reported one of our ‘chasers’ falling in flames, another planing for our own lines, and two or three others turning back. I could see the marauder myself by this time, and noted that it appeared to be heading off about twenty-five degrees to the west of me, and flying already at a level considerably lower than the twelve thousand feet I had run up to in getting away from the last spasm of gun-fire.

“It was this commanding height, together with the fact that my engine was running as sweetly as when it started, that determined me to take a hand in the game at this juncture. Still keeping well up, I promptly headed across to cut off the returning prodigal. For a minute or two the Zepp either didn’t recognise me as ‘enemy,’ or else ignored me entirely. But presently a sharp speeding up of its engines was apparent, and for a moment I thought that it was going to challenge me for a climbing contest, generally a Zepp’s first resort. But a few seconds later it had altered its course through nearly half a quadrant and headed off at top speed, at the same time beginning to descend at what I figured was about an angle of ten per cent., or five hundred feet to the mile. The ruse—to draw me down over some concealed line of ‘Archies’ in that direction—was plain as day; but I had three thousand feet of altitude to the good, power to burn, and, moreover, was bitten deep for the moment with that ‘air-god’ bug I have spoken of. It seemed as natural that I should chase Zepps as that a fox-terrier should chase chickens. Without further thought, I accepted the challenge and launched off in pursuit of the speeding ‘sausage.’

“It really never occurred to me to discuss the thing with K——, but, like the trump he was, he never showed by word or sign that tilting at airships had not been included in our orders. He, also, twigged the game at once.

“‘Guns probably in that thick clump of trees by the little pond,’ his far-away voice said over the telephone. ‘Best catch him as far this side there as you can. One of his engines missing badly, and he’s not going very fast.’

“With a quarter of an hour instead of a couple of minutes to work in, I would have preferred to keep along on a comparatively high level, and only descend, to drop my bombs, at an angle that would have kept me pretty well out of the range of the Zepp’s guns. But K——’s warning was too sound to be disregarded and, in this case, the quickest way was also the only way. As it was, it was really almost a nose-dive, and I did the first half of it with the throttle wide open. So fast did we come up with the Zepp that it seemed almost as if a giant had taken the big gas-bag in his hand and thrown it at us.

“The patter of machine-gun bullets sounded only for a second or two—it wasn’t unlike walking over a lawn-sprinkler—and, so far as I could see, did no harm. Then, cold as ice for the work in hand, I shot straight down along the yellow spine of the airship, letting go a couple of bombs before my terrific speed carried me beyond my mark.

“Now a perfect torrent of shrapnel burst out around me—the smoke-tufts made the still distant clump of trees look like a cotton field—and almost at the same instant there was a strong rush of air from below. The machine teetered giddily on one wing-tip for a moment, and I just managed to right it in time to free a hand to grab the tail of K——’s coat as he, apparently unconscious, started to lurch over the side. I don’t seem to have any very clear recollection of being able to get him back into his seat at all.
