“You know perfectly well you didn’t,” I replied, folding a corner of the old match-seller’s straggling cloak back over her knees and sitting down in the space vacated. “Go to it.”

“I was starting on a reconnaissance over a corner of Belgium just as the Zepp was returning from a raid over France. I got above him, and just after I dropped my first bomb the ‘Archies’ opened up on me from the ground and put me out at just about the first shot. Jolly nervy work, with my machine only a couple of hundred feet above the Zepp. A little too nervy, perhaps, for I’ve never been quite certain in my own mind whether it was my bomb or one from the German guns which sent the Zepp—not wrecked but pretty badly messed up—down into a sugar-beet field. I headed——”

“Just a moment,” I interrupted, anticipating the end of the tale at the end of Horne’s next breath. “You’re dumping over your story just the way a Zeppelin under fire dumps over its bombs. Now please back up and tell it properly. The night is young, the raiders are now headed out to sea, and the lady and I are here to follow you to the end.”

Horne laughed uneasily, fumbled through his pockets in a vain search for matches, filched a box from the tilted tray of our nodding companion,—leaving a sixpence in its place,—lit his pipe, puffed pensively for a minute or two; and even after all that preparation made his beginning apologetic.

“I don’t know that I’ve ever told the yarn from the beginning,” he said, “and I’m dead sure I’ve never said much about the end. If I chatter a bit to-night, you’ll please check it up against the good news I had a while ago—and the air. A man could pretty nearly walk on the air as it has been to-day, and a machine would slide through it like tearing silk. Funny thing, but it was in the dawn following almost just such a night as this that I went off on the flight I have spoken of.

“There are three main factors in flying,”—Horne spoke more freely again as he digressed upon generalities,—“the man, the machine, and the atmosphere. Theoretically, man and machine are supposed to be sent out in perfect order, ready to take the air as they find it. There are days, of course, when you are ‘off’, your machine ‘cranky,’ and the air all ‘heights’ and ‘hollows,’ and at such times there is pretty sure to be a ‘stormy passage,’ if nothing worse. Usually, however, it’s a fairly fit man and machine against indifferent air. But once or twice a year there comes a period, like the last eighteen hours, when the air is almost absolutely ‘homogeneous,’ and then, with his engine running ‘sweet,’ the man has spells of fancying himself an ‘air god’ in fact as well as in name, and acts accordingly,—invariably either to his own or his enemy’s sorrow.

“It was like that on the morning I am telling you about—man, machine, and air all in harmony—yes, and with the usual result. I would have remembered this flight for several reasons, even if the Zepp hadn’t come along; for one, because of our ride down the wake of a ‘42’ shell; for another, on account of the terrific shelling they gave, or tried to give us, as we passed over the German lines.

“The meeting with the shell was merely one of those freak experiences that might happen to any one, or, just as well, never happen at all. It was during the time I am speaking of that the Germans were amusing themselves by a long-distance bombardment of N—— with their biggest guns, and we—(I had an observation officer along, a chap named K——, whom you may have heard of as a long-distance runner)—simply chanced to meander into the path of one shell somewhere about the last quarter of its trajectory. Watching from a distance, you can always see one of these brutes go hurtling along, but this one we only heard,—and felt,—and it was like two express trains, going in opposite directions, passing at full speed. There was a strange soft sort of a buzz, growing into a rushing roar inside of two or three seconds, a blow from a solid wall of air that was like colliding with the side of a house, and then, for two or three minutes, a series of bumps like going over a corduroy road in a springless cart.

“I don’t know whether we interfered very much with the course of that shell, but the shell pretty nearly brought our flight to an end then and there. Only the fact that we met the first big rush of air head-on saved us. I wouldn’t have had one chance in a thousand of ‘correcting’ if it had caught us sideways—and even as it was, the machine, in spite of its seventy-miles-an-hour headway, was stood up on its rudder like a rearing horse. After that first ‘collision,’ our fluttering flight down the wake of the ‘42’ was only ‘queer,’ but withal a different sensation from anything I had ever experienced.
