I found the atmosphere of the cabins, as my friend Bonflon had asserted, agreeable and healthful. I could also occupy the promenade deck for half an hour with little inconvenience, so far as the levity of the air was concerned; but the cold was severe; while the system, in consequence of an undue expansion of its particles, solid and fluid, from the diminished pressure of the atmosphere, was rendered doubly susceptible to its influence. The advice given by Mr. Bonflon to case myself in flannels, with an armament at hand of outer winter clothing, proved well-timed; and yet a period of lassitude, verging on faintness, invariably followed every considerable exposure to the open air. But the pleasure of gazing on those fields of space without obstruction, without the intervention of so much as a plate of crystal glass, repaid me for every risk and every ill. Though it might be said there was no scenery there, where nothing was visible but the stars, yet far beyond the power of mountain and valley, forest and lake, waterfall and ocean, did that scene, which was no scene, or next to none, bind me in the spell of its fascination. The motion of our craft, as we careered noiselessly through the shoreless and objectless void, without sense of effort or friction, was a charm of itself,--bringing to a flower, crystallizing into refulgent stars, the dim, obscure, however glorious, poetry of life. Here were the wildest imaginations of the dreamer melted in a crucible, and reproduced in living forms of usefulness and beauty. In my own years of widely diversified experience, what had I met with to compare with this? Nothing. The force of steam was marvellous,--talking over a wire mysterious; but here I was in a great ship riding among the planets and the stars. I had likened Niagara to a vast mill-dam, because I could find no peer to set beside it; so now, in my weakness, the sublime pageant of the "Flying Cloud" could search out nothing higher in my recollection with which to compare it than a wild, ride of my youth in a canoe, for a half mile or so, down the rapids of a river. But morning was at hand. The rich golden glow of night, to which the dwellers on the earth's surface are accustomed, as we passed to higher altitudes, had given place to a thin inky blue. This was obscured by no fleck or mist, and yet the stars shone through it faint and dim, despoiling the firmament of its glory. The same loss of power was manifest on the ushering in of day. The auroral flame, which ordinarily greets us in the east with such a ruddy laugh, was now nothing better than a wan and dismal smile; and even the sun, as he struggled up from what seemed a bed of leaden mist, brought with him only a pallid, lifeless twilight. It was not that his rays were impeded by cloud or haze; he had lost his power to shine. He hung there in the heavens like a great white shield, and looked down on us as rayless and powerless and devoid of life as a dead man's eye.
