In fact, we know no river, north of the sources of the Nile, that does not fall into the Nile. Nay, I may say, that not one river, in all Abyssinia, empties itself into the Red Sea. The tropical rains are bounded, and finish, in lat. 16°, and there is no river, from the mountains, that falls into the desert of Nubia; nor do we know of any river which is tributary to the Nile, but what has its rise under the tropical rains. It would be a very singular circumstance, then, that the Frat should rise in one of the dryest places in the globe, that it should be a river at least equal to the Nile; and should maintain itself full in all seasons, which the Nile does not; last of all, in a country where water is so scarce and precious, that it should not have a town or settlement upon it, either ancient or modern, nor that it should be resorted to by any encampment of Arabs, who might cross over and traffic with Jidda, which place is immediately opposite. On the 18th, at day-break, I was alarmed at seeing no land, as I had no sort of confidence in the skill of my pilot, however sure I was of my latitude. About an hour after sun-set, I observed a high rugged rock, which the pilot told me, upon inquiry, was Jibbel, (viz. a _Rock_), and this was all the satisfaction I could get. We bore down upon it with a wind, scant enough; and, about four, we came to an anchor. As we had no name for that island, and I did not know that any traveller had been there before me, I used the privilege by giving it my own, in memory of having been there. The south of this island seems to be high and rocky, the north is low and ends in a tail, or sloping bank, but is exceedingly steep to, and at the length of your bark any way from it, you have no soundings.
