We have been making inquiries of the Tanelkums about the population of Ghât and its deserts. The Tanelkums say, that ten or twelve years ago Khanouhen brought up about ten thousand maharees against the then masters of Mourzuk, the Walad Suleiman, headed by Abd-el-Galeel. The ten thousand maharees were the whole force and strength of the Azgher, Khanouhen having called out every male; for every man of the Azgher is a warrior. The Arabs, seeing the number of the Tuaricks, deemed it expedient to make peace. From this circumstance, it would be supposed that the Azgher may number from five to ten thousand families, nearly all located west of the Soudan route, along the lines of the Ghadamez and Tuat routes; where, it is said, there are fertile valleys, in which dates and corn are cultivated. But at Ghât I could never learn anything of these wadys. During my last visit I had no time, and the people there had no inclination to give me information about this fertile portion of the Azgher desert. On the former occasion, I learned from Haj Ahmed that there was a running stream, on the banks of which corn was cultivated, at about four days west of Ghât. This is probably the locality of Janet. For myself, I do not believe the Azgher Tuaricks number more than two thousand families. Of the population of Aheer I have been able to learn nothing definite; that is to say, nothing which I can absolutely depend upon. Some make it reach above fifty thousand souls. There are, however, only forty towns, exclusive of Aghadez; and about twenty places where people live in tents. I wrote down a second list of them, with their directions, and some guess at the number of male inhabitants. The son of the Tanelkum Sheikh considers the Kailouee warriors to amount to about fourteen thousand; which, indeed, will make the whole population above sixty thousand. The accounts I have received, therefore, seem to be sufficiently exact for general purposes.
