Tuat is mentioned in many maps as a town; but it is a large tract of country on the borders of Soudan, inhabited chiefly by Tuarick. It is situated on the Great Desert, and is not very fertile. Fine horses are bred there, and the flocks are numerous. The natives trade with Tembuctoo, Soudan, Ghadams, and Fezzan, but seldom go so far east as Bornou. The chief length of the country is from north to south, and the towns bear very nearly in that direction to each other. The houses are built of stone and mud, and have no second story; many of the towns are walled. Ain el Salah, or the Fountain of Saints, is the principal town. It takes its name from the sanctity of its inhabitants, who have all the credit of being Marāboots. A story is told of its having 366 castles, which were built by the first Mohammedan conquerors of the country; they are said to be of a great height and in fine preservation. I suspect, however, they are pretty nearly of the same description as those of Fezzan, of which we heard so many wonderful accounts, and which proved to be only mud tombs, or remains of old houses. From Morzouk to this place is about forty days’ journey. West. In Fezzan {Morzouk to Tessowa 1 day. Town and old castle. {Tessowa to Oubāri 2 Town. Oubāri to Haghki 2 Resting place.

Houhaned to Oonabraghri 4 do. Oonabraghri to Ain el Sala 2 Town in Tuat. Between Tadera and Amaghi is a desert, which is travelled eight days without water. All the road is sand without any other vegetation than a few occasional shrubs, from Morzouk to Ain el Sala, which is the northern town in Tuat, and the first reached by all the Kafflés from the coast of Morocco. Tafilet is ten days north-west of it. Tombuctoo, or Tembuctoo, is fifty days from Ain el Sala, and the road is entirely over a desert. The first place from Ain el Sala is Akably, a very large town, which is two days. From thence to Mabrook is thirty-five days: this place is so called from its being the custom for those who have passed the Desert to rest and refresh there, each congratulating the other on having safely arrived over their perilous road, by the usual salutation of “Mabrook,” which signifies joy or happiness. Hence to Tembuctoo is fifteen days. Ghadams, belonging to the Bashaw of Tripoli, is twenty days north-north-west of Ain el Sala.
