Once I was carried away by the chorus of a song which made me dream a little as I sang. I looked down. There lay the straight road quite in order as I left it, but alongside appeared a forest which was not marked on the map. I became worried. I knew that once I had lost the way I would be badly adrift.

Just in time I discovered that I had passed a fork in the road as I sang to myself, and we had not turned as we should have done. Thereafter I kept my eyes on the alert, till finally we reached the outskirts of Paris.

When we were low over the roofs near Villacoublay I happened to look at the height-indicator. To my surprise it registered zero. I gave the pilot a violent nudge and pointed it out to him. Then I realised that the aerodrome at Luxeuil, on which the indicator had been adjusted, was several hundred feet above sea-level, and that, now we were over lower country, our height might be registered as nothing, when in reality we were a few hundred feet above the roofs.

If there had been a mist we might have been in a difficulty, as our height-indicator would have been useless. We would not have had the good fortune of an airman who on one occasion got overtaken by a thick mist in England and wished to land. He knew the country was flat, so he glided down into the mist very gently, and when the height-indicator was just above zero he climbed out of the machine and sat on the edge. He saw the finger of the dial actually touch the zero mark, and jumped.... So accurate was the instrument that he was not hurt. He was flung down a bank, and was badly shaken up, but was no worse for it. The amazing part of it was that the aeroplane, a very stable machine, landed itself correctly and was found in a field a little farther ahead without a wire broken.

We landed at Villacoublay, and rushed into Paris by car to spend a gay glittering evening in the capital. We were up early next day, and motored out to Villaconblay, and were soon on our way to Dunkerque.

A little past Boulogne the low-drifting clouds were left behind, and we flew into glorious April weather. On the left, to my great joy, was the sea and the surf-lined sweep of the coast. Below was the patchwork of fields and meadows, whose colours were so soft in the sunlight that the country looked like a carpet of suède leather dyed with many a rich shade of cream and brown and purple and dull green, in oblong patternings. Across this lovely mosaic ran straight roads which linked up the compact little towns. Here and there lay a canal like a bar of steel, blue and slender.

The machine moved forward with an absolute steadiness. The pilot took his hands off the wheel, glad to rest himself after the terrific bumping we had been enduring under the clouds since we left Paris. The engines droned contentedly. The burly engineer P.O. in front looked downwards with delight at the sunny plain which moved towards us with such a stately and even progress. Flying became really comfortable for once, and very monotonous.

Calais passed. Gravelines, with its starfish fortifications, moved by on our left-hand side. Dunkerque lay ahead. I began to look for the aerodrome. I had not been told exactly where it was. I knew it was between Dunkerque and Bergues, near the canal. Nearer and nearer to Dunkerque and its line of docks and its ramparts we drew. Still I could not find the aerodrome. The pilot grew impatient. Then I saw in the air ahead of us the familiar form of a twin-engined machine. It was another Handley-Page. It swept downwards in wide curves. I looked below it and saw, by a wide field, a few brown hangars in front of which stood other machines.

The noises of the engines ended. We drifted down and landed. We were met by an officer with a megaphone, who gave us very curt instructions as to where the machine was to stop. We expected to be greeted as heroic travellers, so this abrupt welcome rather surprised us. When we disembarked, however, we found that several Handley-Pages were coming back from a daylight patrol off the coast to Zeebrugge and back. I caught the edge of my pilot's eye and knew he was wondering as I was—what nasty new business was this?

We went into the mess, very tired after our long journey by air from one end of the lines to the other, and while we were sitting at the table a heavy-booted and furred observer came in with very bright eyes and said to the C.O. of the station
