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. Then for a moment a great rift in the barrier appears beneath us. Across the dark space with its edges of ragged white lie two hard beams of light. Then we see, far below, a chain of green balls rush up from the darkness, and as they appear they light up a great circle of the earth, and slowly there appears nearly the whole of Ostend lit up by a ghostly greenish light. I see the shining sea, the line of the shore broken by the groins, and the huddled roofs of the houses. For a moment the scene is clear and distinct, then with the upward course of the balls of light it dies away, and the two searchlights throw blinding bands across a pool of obscurity. What we have seen, however, is a sufficient guide. We know we are above the coast. The machine swings to the left, and above the rippling spots of light we roar on westwards. Soon we leave this fantastic dancing floor behind us, and, seeing through the misty curtains a watery glow of white light blossom out into a hazy gleam and fade away, we know that we are somewhere near the lines.
