"Excuse me, sir," said he to a Brass Hat, "I represent the civil authority. Will you please tell me if this"—pointing to me—"is the captive baby-killer?"

"Now give us the chorus, old son," said Marmaduke. Explanations followed, and the Bing Boys retired, rather crestfallen.

It is embarrassing enough to be mistaken for a German airman. It is more embarrassing to be mistaken for an airman who shot down a German airman when there was no German airman to shoot down. Such was the fate of the four of us—two pilots and two observers—when we left our field to the cow and the conference of Brass Hats, and drove to the Grand Hotel. The taxi-driver, who, from his enthusiastic civility, had clearly never driven a cab in London, would not be convinced.

"No, sir," he said, when we arrived at the hotel, "I'm proud to have driven you, and I don't want your money. No, sir, I know you avi-yaters are modest and aren't allowed to say what you've done. Good day, gentlemen, and good luck, gentlemen."

It was the same in the Grand Hotel. Porters and waiters asked what had become of "the Hun," and no denial could fully convince them. At a tango tea held in the hotel that afternoon we were pointed out as the intrepid birdmen who had done the deed of the day. Flappers and fluff-girls further embarrassed us with interested glances, and one of them asked for autographs.

Marmaduke rose to the occasion. He smiled, produced a gold-tipped fountain-pen, and wrote with a flourish, "John James Christopher Benjamin Brown. Greetings from Dovstone."

But Marmaduke the volatile was doomed to suffer a loss of dignity. He had neglected to bring an emergency cap, which an airman on a cross-country flight should never forget. Bareheaded he accompanied us to a hatter's. Here the R.F.C. caps of the "stream-lined" variety had all been sold, so the war baby was obliged to buy a general service hat. The only one that fitted him was shapeless as a Hausfrau, ponderous as a Bishop, unstable as a politician, grotesque as a Birthday Honours' List. It was a nice quiet hat, we assured Marmaduke—just the thing for active service. Did it suit him? Very well indeed, we replied—made him look like Lord Haldane at the age of sixteen. Marmaduke bought it.

The monstrosity brought us a deal of attention in the streets, but this Marmaduke put down to his fame as a conqueror of phantom raiders. He began, however, to suspect that something was wrong when a newsboy shouted, "Where jer get that 'at, leftenant?" The question was unoriginal and obvious; but the newsboy showed imagination at his second effort, which was the opening line of an old music-hall chorus: "Sidney's 'olidays er in Septembah!" Marmaduke called at another shop and chose the stiffest hat he could find.

By next morning the mist had cleared, and we flew across the Channel, under a curtain of clouds, leaving Marmaduke to fetch a new machine. When you visit the Continent after the war, friend the reader, travel by the Franco-British service of aerial transport, which will come into being with the return of peace. You will find it more comfortable and less tiring; and if you have a weak stomach you will find it less exacting, for none but the very nervous are ill in an aeroplane, if the pilot behaves himself. Also, you will complete the journey in a quarter of the time taken by boat. Within fifteen minutes of our departure from Dovstone we were in French air country. A few ships specked the sea-surface, which reflected a dull grey from the clouds, but otherwise the crossing was monotonous.

We passed up the coast-line as far as the bend at Cape Grisnez, and so to Calais. Beyond this town were two sets of canals, one leading south and the other east. Follow the southern group and you will find our immediate destination, the aircraft depôt at Saint Gregoire. Follow the eastern group and they will take you to the Boche aircraft depôt at Lille. Thus were we reminded that tango teas and special constables belonged to the past.
