A large vessel, however, does not dare to try this, whilst constantly among shoals, and close on a lee-shore; but those sewed together, and yielding without damage to the stress, slide over the banks of white coral, and even sometimes the rocks. Arrived at this island, they set their prow towards the opposite shore, and cross the Channel in one night, to the coast of Arabia, being nearly before the wind. The track of this extraordinary navigation is marked upon[164] the map, and it is so well verified, that no ship-master need doubt it.
About three o’clock in the afternoon, with a favourable wind and fine weather, we continued along the coast, with an easy sail. We saw no appearance of any inhabitants; the mountains were broken and pointed, as before taking the direction of the coast; advancing and receding as the shore itself did. This coast is a very bold one, nor was there in any of the islands we had seen, shoals or anchoring places, unless upon the rock itself; so that, when we landed, we could run our boltsprit home over the land.
This island, Jibbel Macouar, has breakers running off from it at all points; but, though we hauled close to these, we had no soundings. We then went betwixt it and the small island, that lies S. S. E. from it about three miles, and tried for soundings to the leeward, but we had none, although almost touching the land. About sun-set, I saw a small sandy island, which we left about a league to the westward of us. It had no shrubs, nor trees, nor height, that could distinguish it. My design was to push on to the river Frat, which is represented in the charts as very large and deep, coming from the Continent; though, considering by its latitude that it is above the tropical rains, (for it is laid down about lat. 21° 25´), I never did believe that any such river existed.
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.
