“Those on the horizon gave us the notion of a distant conflagration. In proportion as we approached them, these masses of lights appeared to increase, and to cover a greater space, until, when right over them, they seemed to divide themselves into different parts, to stretch out in long streets, and to shine in starry quadrangles round the squares, so that we could see the exact plan of each city, given as on a small map. It would be difficult to give an idea of what sort of effect such a scene in such circumstances produces. To find oneself transported in the darkness of night, in the midst of vast solitudes of air, unknown, unperceived, in secret and in silence, exploring territories, traversing kingdoms, watching towns which come into view, and pass out of it before one can examine them in detail--these circumstances are enough in themselves to render sublime a science which, independent of these adjuncts, would be so interesting. If you add to this the uncertainty which, increasing as we went on into the night, began to assail us respecting our voyage, our ignorance of where we were, and what were the objects we were attempting to discover, you may form some idea of our singular position.” About midnight, the travellers found themselves above Liege. Situated in the midst of a thickly-peopled country, full of foundries, smelting works, and forges, this town was quite a blaze of light. The gas-lamps with which this town is so well lighted, clearly marked out for our travellers the main streets, the squares, and the public buildings. But after midnight, at which time the lamps in continental towns are mostly put out, the whole of the under world disappeared from the view of the aeronauts. “After the turn of the night,” says Mason, “the moon did not show itself, and the heavens, always more sombre when regarded from great altitudes, seemed to us to intensify the natural darkness. On the other hand, by a singular contrast, the stars shone out with unusual brilliancy, and seemed like living sparks sown upon the ebony vault that surrounded us. In fact, nothing could exceed the intensity of the night which prevailed during this part of our voyage. A black profound abyss surrounded us on all sides, and, as we attempted to penetrate into the mysterious deeps, it was with difficulty we could beat back the idea and the apprehension that we were making a passage through an immense mass of black marble, in which we were enclosed, and which, solid to within a few inches of us, appeared to open up at our approach.”
