Now that our job is done, we are not so fearful of being over enemy country, partly because we are used to it by now, and partly because we are leaving the interior farther and farther behind us, minute by minute, as the coast-line draws nearer.
Unexpectedly I notice below the machine a curious white patch on the face of the country. Then I see others behind it, and realise that the coast-line is becoming swiftly blotted out under a layer of clouds.
"Jimmy! Look—clouds! We'll have to go carefully," I remark, and have a look at the compass. "Let's turn a bit more south-east, and we are bound to see Ostend."
We turn swiftly, and in a few minutes are above a white carpet of cloud, through which, to my joy, I can see very hazily the flashing light of Blankenberghe to my right. Over towards Zeebrugge rise a few parting strings of green balls as the last British machine turns out to sea.
For ten minutes we fly on by compass, which I check by the coldly glittering North Star, that shines faithfully for us high in the deep blue of the sky.
Then I see, running to and fro, and round and round, on the carpet of the clouds, little circles of light. Now and then one comes to a rift on the bank, and for a moment a beam of light shoots up into the sky, only to vanish again. The Ostend searchlights are vainly looking for us; our engines have been heard.
Now we are approaching a new formation of clouds, lovely towering masses of cumulus, pearl-white in the light of the moon. Over an unreal world of battlement and turret, of mountain summit and gloomy valley, we move in a splendid loneliness beneath the scattered stars. This billowy world of soft and silvery mountain ranges is made the more strange by the restless discs of radiance which run and swoop and circle and dance in a mad maze of movement across the curving pinnacles and ravines. Now and again a searchlight, striking into the heart of some towering summit of cloud, illuminates it with a glorious radiance, so that it seems for a moment to be woven of the fabric of light.
Suddenly the scene becomes even more fantastic, for in one place on the clouds appears a spot of vivid green. The spot of light spreads and spreads until it is a circle of emerald light, a mile or more in diameter, and from the extreme centre appears a ball of brilliantly green fire which pops out of it quickly, to be followed by another and another, until the whole chain of beads have freed themselves from the entanglements of the vapour and rush gaily upwards high over our heads, to end their brief career in a lovely splendour above the milk-white billows of the cloudy sea.
Another point of cloud glows green, there is another swiftly expanding circle of colour, and another string of these quaint gems float upwards in a swaying curve. The sight is one of such exquisite loveliness that it is difficult to describe it. It is all so beautiful—the star-scattered vault of night, gold flowers in a robe of deepest blue: the soft white wonder of the rolling clouds, mile upon mile, as far as you can see, moonlit and magic, a playground for the gambolling figures of light which, like a host of Tinker Bells, rush deliriously from side to side, climb up hills and slide down valleys, and jump excitedly from peak to peak: the expanding flowers of emerald light from whose heart rise the bizarre bubbles of scintillating brilliance, to live through a few glorious seconds of ecstatic motion before they die in the immensity of the night.
It is a scene of a strange and ever-altering beauty, and one that very few eyes have seen. It is a world beyond the borders of the unreal. Forgotten is the material country of fields and forests far below—as forgotten as it is unseen. To a paradise of vague moon-kissed cloud we have drifted, and float, dreaming, between the stars of heaven and the purgatory beneath.
