A narrative&nbsp;of an odd undertaking to a foreign land. Odd, in the first place, insomuch that for the greater part of a year a man&rsquo;s tongue was mute to the language of his race, for the land where he travelled was native: first to the Hausa people; later to Hausa, Beri-Beri, Fulani and Tuareg; and later still to Tuareg alone; while over all there was a mere handful of French Europeans, who were the military administrators of law and order.<br />The country was that known as the Territoire Militaire du Niger of the Western Sudan, wherein, remote and in the midst of desolate seas of sand, lies the wild brooding mountain country of A&iuml;r or Asben&mdash;which was the traveller&rsquo;s goal.<br />It might be said that the traveller was a rude man, for he was untutored in the deep studies of the scholar of many languages, as in a measure might be expected and understood of one whose occupation called him from day to day to don rough clothing and shoulder a rifle and march outside the frontiers of civilisation.
