About five o’clock in the evening we sighted to the north the Cape of Ras-Mohammed. This cape forms the extremity of Arabia Petraea, comprised between the Gulf of Suez and the Gulf of Acabah. The Nautilus penetrated into the Straits of Jubal, which leads to the Gulf of Suez. I distinctly saw a high mountain, towering between the two gulfs of Ras-Mohammed. It was Mount Horeb, that Sinai at the top of which Moses saw God face to face. At six o’clock the Nautilus, sometimes floating, sometimes immersed, passed some distance from Tor, situated at the end of the bay, the waters of which seemed tinted with red, an observation already made by Captain Nemo. Then night fell in the midst of a heavy silence, sometimes broken by the cries of the pelican and other night-birds, and the noise of the waves breaking upon the shore, chafing against the rocks, or the panting of some far-off steamer beating the waters of the Gulf with its noisy paddles. From eight to nine o’clock the Nautilus remained some fathoms under the water. According to my calculation we must have been very near Suez. Through the panel of the saloon I saw the bottom of the rocks brilliantly lit up by our electric lamp. We seemed to be leaving the Straits behind us more and more. At a quarter-past nine, the vessel having returned to the surface, I mounted the platform.
