As for the Kél-fadaye they are the original and real inhabitants of the district Fáde-ang, which lies round Tághajít; while the Éfadaye, who have been called after the same district, are rather a mixture of vagabonds flocking here from different quarters, and principally from that of the Azkár. But the Kél-fadaye, who, as well as their neighbours the Éfadaye, took part in the ghazzia against the expedition on the frontiers of Aïr, are a very turbulent set of people, being regarded in this light by the natives themselves, as appears from the letter of the Sultan of Ágades to the chiefs Ánnur and Lúsu, of which I brought back a copy, wherein they are called Mehárebín, or freebooters. Nevertheless they are of pure and noble Berber blood, and renowned for their valour; and I was greatly astonished to learn afterwards from my noble and intimate friend and protector the sheikh Sídi Ahmed el Bakáy, that he had married one of their daughters, and, had long resided amongst them. Even from the letter of the Sultan of Ágades it appears that they have some relations with the Awelímmiden. The name of their chief is Shúrwa. The Kél-ferwán, though they are called after the fine and fertile place Iferwán, in one of the valleys to the east of Tintágh-odé, where a good deal of millet is sown, and where there are plenty of date-trees, do not all reside there at present, a numerous portion of them having settled in the neighbourhood of Ágades, whence they make continual marauding expeditions, or “égehen,” upon the Timbúktu road, and against the Awelímmiden. Nevertheless the Kél-ferwán, as the kinsmen of the Aurághen, and the Amanókalen (that is to say the clan to which, before the different tribes came to the decision of fetching their Sultan from Sókoto, the family of the Sultan belonged) are of nobler and purer blood than any of the rest. As an evidence of their former nobility, the custom still remains that when the Sultan of Ágades leaves the town for any length of time his deputy or lieutenant in the place is the chief of the Kél-ferwán. The third tribe of those who are under the direct authority of the Sultan of Ágades, viz. the Izeráren, live between Ágades and Damerghú. But I did not come into contact with them. The Kél-gerés and Itísan seem to have been originally situated in the fertile and partially beautiful districts round the Bághzen, or (as these southern tribes pronounce the name in their dialect) Mághzem, where, on our journey towards Damerghú, we found the well-built stone houses in which they had formerly dwelt.
