They were now floating tranquilly in the vast solitude of heaven, over a teeming continent mantled in night and mystery. Far along earth’s sable surface gleam the scattered fires of many villages; and above it the lovelier fires of a moonless sky. Unseen, unsuspected, they survey kingdoms and cities, trailing their long rope serpent-like over woodland, field and quiet homestead. Now on the horizon before them looms a greater fire, like a distant conflagration, widening as they approach. Gradually it expands into a model city, shooting out long lines of illuminated streets; here the public squares, markets and theatres; there the rumbling iron mills with blazing furnaces. They are above Liege at her festive hour, murmuring with animation and busy life. Again they drift into the dark regions of slumber, lapped in silence and deep tranquillity, where the lights of men are extinguished, and the stars, redoubling their lustre, gleam whitest silver in heaven’s jetty dome. Midnight involves the world; an abyss of darkness enfolds it; their solitary lamp seems to melt its way through solid space of blackest marble. For hours they undulate over the rolling hills, rising and falling a thousand cubits, held always to earth by the trailing rope. At times they are so near as to trace the landscape dimly; here a white tract covered lightly with snow, here a dark valley or forest, here a tortuous river, probably the Rhine, with its multitudinous thunder of waters. But in all that weird and obscure wandering no joyous note of human or animal life ascends ere dawn to cheer their solitary course in the sky. At last the paling of the morning star, and a faint tingeing of the eastern cumuli, announce the expected day. With sudden bound the great ship mounts aloft twelve thousand feet, into the glory of the blazing sun, new risen among clouds of amber and purple. Far below, twilight and mist still mantle the half-awakened world, presenting a stupendous panorama, vast as an empire. Presently down they plunge into the vaporous and obscure atmosphere, drifting carelessly, but soon reascending into the splendor of morning. Thus after making the sun rise three times and set twice, they float contentedly along the misty landscape, marveling what region lies below them, whether a barren wilderness, or the abode of civilized life, with human comforts and a ready means of transportation. A hot breakfast would be very welcome now; for they had accidentally dropped the lime pot and had spent the latter half of the night without warm beverage in a region where oil and water had frozen.
