The country, in the neighbourhood, is planted with vines, olives, figs, pomgranates, almonds, oranges, and cotton of an excellent quality; at Rabat there is a manufactory of cotton cloth, which is made more for durability than sale. There are docks for ship-building at Salée, as well as at Rabat; at the latter place, when I was last there, the hulls of two sloops of war were nearly finished; I went aboard of them, and was astonished to learn that they had been built by a man who must have had a natural genius for ship-building, as he built them _by the eye_, without the use of rules and compasses, a circumstance which appeared to me very extraordinary and incredible; but I was repeatedly informed by many of the inhabitants of Rabat, Moors, Jews, and Christians, that it was a known fact, and might be ascertained by going to see the daily progress made in the building of them. The road of Salée is dangerous for shipping, and the accumulation of sand at the entrance, will scarcely permit a vessel of 100 tons to enter the river without danger. Vessels may lie in safety out of the river, near Rabat, from April till September inclusive; but they are not secure the rest of the year, the wind blowing from the southern quarter, and often obliging them to quit their moorings. The best anchorage in this season, is between the Mosque of Rabat and the old Tower of Hassen, having the latter to the north. A great number of anchors having been lost, much attention must be paid to the cables and buoys. Rabat stands in 34° 3′ N. lat. On the eastern side of Rabat is a walled town named Shella: this is sacred ground, and contains many Moorish tombs, held in great veneration: the town is a sacred asylum, and is entered only by Mohammedans. Once, however, when I was staying at Salée, an English captain dressed himself in the Arabian habit, and accompanied by a confidential friend, entered this sacred town, and viewed what his guide told him were the tombs of two Roman generals; but he had not time to examine the inscriptions thereon, for fear of exciting observation. Shella was probably the Carthaginian metropolis on the coast of the ocean. Various Roman and ancient African coins used to be continually dug up here, but the exorbitant price given for them by some agents of European antiquarians, induced the Jews to imitate them, which they did so correctly, that these amateurs were deceived; and lately people have fallen into the opposite extreme, being now so over cautious as to dispute even the antiques themselves; for this reason the Moors often sell them to the silver and goldsmiths for their weight in silver. The last time I was in Africa, I collected a number of these coins, but the vessel, in which I was coming to England, sprung a leak, and foundered: and although I saved some clothes, I could not get at the coins, which were stowed away in a secret part of the ship, to be secure from discovery, in the event of our falling in with any French privateer.
