We sailed in the night from Zimmer. When we came nearer the channel, the islands were fewer, and we had never less than twenty-five fathom water. The wind was constantly to the north and west, and, during all the heat of the day, N. N. W. At the same time we had visibly a strong current to the northward. The 9th, at six o’clock in the morning, the island Rapha bore N. E. by east, distant about two leagues, and in the same direction we saw the tops of very high mountains in Arabia Felix, which we imagined to be those above Djezan; and though these could not be less than twenty-six leagues distance, yet I distinguished their tops plainly, some minutes before sun-rise. At noon I observed our latitude to be 16° 10´ 3´´ north, so we had made very little way this day, it being for the most part calm. Rapha then bore E. ¾ north, distant thirteen miles, and Doohaarab N. N. W. five miles off. We continued under sail all the evening, but made little way, and still less during the night. On the 10th, at seven in the morning, I first saw Jibbel Teir, till then it had been covered with a mist. I ordered the pilot to bear down directly upon it. All this forenoon our vessel had been surrounded with a prodigious number of sharks. They were of the hammer-headed kind, and two large ones seemed to vie with each other which should come nearest our vessel. The Rais had fitted a large harpoon with a long line for the large fish in the channel, and I went to the boltsprit to wait for one of the sharks, after having begged the Rais, first to examine if all was tight there, and if the ghost had done it no harm by sitting so many nights upon it. He shook his head, laughing, and said, “The sharks seek something more substantial than ghosts.” “If I am not mistaken, Rais, said I, this ghost seeks something more substantial too, and you shall see the end of it.”
