The tribes from the left bank of the Niger also move into the kind of islet formed by the bend of the river, advancing to near Dori, where they find a series of ponds and lakes known as Oursi Beli, etc., an idea of which I have tried to give in the map accompanying this volume, but I do not know how far I have succeeded. There are many very curious and interesting hydrographical problems connected with this bend of the Niger reserved for the future explorer to solve. Well, what do my readers think of the Tuaregs after the picture I have endeavoured to give of them? I certainly have not represented them as saints, living in a kind of Utopia, where all is well, where the men have no vices and the women no faults. You will perhaps, however, agree with me that they have very decided characters, and many fine qualities, if also many defects. Their intelligence is certainly great, making it well worth while to try and win them to a better mode of life, and one more conducive to the comfort of their neighbours. I do not of course fail to recognize what hard work it is to row against the current or to contend against pre-conceived ideas. It is always difficult, and sometimes dangerous. In 1859 a young Frenchman, not more than twenty years old at the most, disembarked at Constantine. He spent three years travelling about the Algerian Sahara, and under the powerful protection of the Emir Ikhenukhen, chief of the Azguers, he lived for more than a year amongst the Tuaregs. After his return an expedition was sent out by the Governor of Algeria, and the treaty of Rhadamès was signed. Then, in accordance with the traditional French policy in matters colonial, instead of profiting by the results already acquired, absolutely nothing further was done. Duveyrier described the Tuaregs as he had found them, just as I have tried to do; he spoke quite frankly of their faults as well as of their virtues, and insisted on the possibility of treating with them on favourable terms. He might well do so, for he had already succeeded in that direction himself. When twenty years later Flatters was assassinated, Duveyrier was accused of mendacious optimism, and every one was ready to cast a stone at him. As a matter of fact, however, Flatters was killed by the Hoggars, and Duveyrier had mentioned that they were living in a state of anarchy, which seemed likely to get worse and worse rather than to improve. Flatters insisted on going through their territory, although the Amrar had told him he could not protect him. Now Duveyrier had made a special point of never going into any district without first securing an efficacious safe-conduct, yet in spite of all this he is made responsible for the disaster.
