We find ourselves a mile or two beyond Arras. As soon as the bus appears it is bracketed in front, behind, and on both sides by black shell-bursts. We swerve aside, but more shells quickly follow. The shooting is particularly good, for the Archie people have the exact range of the low clouds slightly above us. Three times we hear the hiss of flying fragments of high explosive, and the lower left plane is unevenly punctured. We lose height for a second to gather speed, and then, to my relief, the pilot zooms up to a cloud. Although the gunners can no longer see their target, they loose off a few more rounds and trust to luck that a stray shell may find us. These bursts are mostly far wide of the mark, although two of them make ugly black blotches against the whiteness of the vapour through which we are rising. Once more we emerge into the open space between sky and cloud. The flight-commander takes the mouthpiece of his telephone tube and shouts to me that he intends completing the round above the clouds. To let me search for railway and other traffic he will descend into view of the ground at the most important points. He now sets a compass course for Toutprès, the first large town of the reconnaissance, while I search all around for possible enemies. At present the sky is clear, but at any minute enemy police craft may appear from the unbroken blue or rise through the clouds. The slowness of our ground speed, due to the fierce wind, allows me plenty of time to admire the strangely beautiful surroundings. Above is the inverted bowl of blue, bright for the most part, but duller towards the horizon-rim. The sun pours down a vivid light, which spreads quicksilver iridescence over the cloud-tops. Below is the cloud-scape, fantastic and far-stretching. The shadow of our machine is surrounded by a halo of sunshine as it darts along the irregular white surface. The clouds dip, climb, twist, and flatten into every conceivable shape. Thrown together as they never could be on solid earth are outlines of the wildest and tamest features of a world unspoiled by battlefield, brick towns, ruins, or other ulcers on the face of nature. Jagged mountains, forests, dainty hills, waterfalls, heavy seas, plateaux, precipices, quiet lakes, rolling plains, caverns, chasms, and dead deserts merge into one another, all in a uniform white, as though wrapped in cotton wool and laid out for inspection in haphazard continuity. And yet, for all its mad irregularity, the cloud-scape from above is perfectly harmonious and never tiring. One wants to land on the clean surface and explore the jungled continent. Sometimes, when passing a high projection, the impulse comes to lean over and grab a handful of the fleecy covering.
