For a quarter of an hour, I trod this blazing sand, which was strewn with tiny crumbs of seashell. Looming like a long reef, the Nautilus’s hull disappeared little by little, but when night fell in the midst of the waters, the ship’s beacon would surely facilitate our return on board, since its rays carried with perfect distinctness. This effect is difficult to understand for anyone who has never seen light beams so sharply defined on shore. There the dust that saturates the air gives such rays the appearance of a luminous fog; but above water as well as underwater, shafts of electric light are transmitted with incomparable clarity. Meanwhile we went ever onward, and these vast plains of sand seemed endless. My hands parted liquid curtains that closed again behind me, and my footprints faded swiftly under the water’s pressure. Soon, scarcely blurred by their distance from us, the forms of some objects took shape before my eyes. I recognized the lower slopes of some magnificent rocks carpeted by the finest zoophyte specimens, and right off, I was struck by an effect unique to this medium. By then it was ten o’clock in the morning. The sun’s rays hit the surface of the waves at a fairly oblique angle, decomposing by refraction as though passing through a prism; and when this light came in contact with flowers, rocks, buds, seashells, and polyps, the edges of these objects were shaded with all seven hues of the solar spectrum. This riot of rainbow tints was a wonder, a feast for the eyes: a genuine kaleidoscope of red, green, yellow, orange, violet, indigo, and blue; in short, the whole palette of a color-happy painter! If only I had been able to share with Conseil the intense sensations rising in my brain, competing with him in exclamations of wonderment! If only I had known, like Captain Nemo and his companion, how to exchange thoughts by means of prearranged signals! So, for lack of anything better, I talked to myself: I declaimed inside this copper box that topped my head, spending more air on empty words than was perhaps advisable.
