These, whom Mr. Horneman styles a _mighty_ people, appear to occupy the habitable parts of the Great Sahara, situated to the west of the meridian of Fezzan. They must necessarily be widely dispersed; and they are also divided into many tribes. Mr. Horneman very properly confines himself to what he _knew_, concerning them: and this knowledge related to little more than to the tribes of _Kolluvi_ and _Hagara_, who live the nearest to Fezzan; and carry on a commerce between that place, Soudan, and Gadamis. The Kolluvi possess (from recent conquest, it would seem,) the country of Agadez; which, with other provinces adjacent, forms a state named collectively, _Asben_. It adjoins to Kashna (a part of the empire of Houssa,) on the south; Bournu on the east. Its capital is the city of Agadez, said, by Mr. Magrah’s informant, to be in size equal to the suburbs of Tunis; which, Mr. Magrah observes, compose the largest proportion of that city. But it would appear by the _Soudan_ route, transmitted by that gentleman, that the establishments of the Tuarick in other places, as Gazer, Tagazee, Jenet, &c. consisted only of small villages, scattered through an immensity of space: indeed, like most of the other tribes situated within this singular region. Zanfara and Guber, which are said to lie adjacent, pay a tribute to Asben. The Hagara are the most easterly of the Tuarick, and are near Fezzan. These I am not able to place on the Map: possibly, they either occupy Ganat, on the south of Fezzan; or, as the Tuarick possess Jenet and Sockna, on the NW of it, the town of Agaree, in the same quarter, may be the Hagara meant. It appears in the routes collected by Mr. Magrah, at Tunis. Mr. Horneman also mentions, but without any notice of situation, the _Matkara_ tribe: also that of _Tagama_, situated towards Tombuctoo and Soudan.[75] He forms an ingenious conjecture respecting this tribe. They are said to be whiter than the rest of the Africans of the interior (or rather, perhaps, less black); and are _not_ Mahometans. Now, as the term _Nazary_, or Christian, is applied generally to those whom the Mahometans call unbelievers, Mr. Horneman infers that this circumstance has given rise to the report of there being a tribe of _white Christians_ near Tombuctoo.[76] The eastern Tuarick live chiefly a Nomadic life.
