CHAPTER II FORGOTTEN RIVERS ' From Maqainama onwards there is nought more but the Rub6 al Khali until you come to the settlements. There is water to the right of it and water to the left of it, but that is the Rub' al Khali.* WE had, as I reckoned, entered the Great South Desert when we passed out of the Juba basin at Hafair. Now we were properly embarked on the sands as we set our course roughly eastward from Maqainama for Bir Fadhil. And Suwid swept his arm comprehensively round to south and west as he imparted to me the information with which I have opened this chapter. I have no doubt whatever in my own mind that, while the Arabs in general know and use the term c Rub' al Khali' to indicate the vast, vague, unknown wilderness of the Great South Desert extending between Jabrin and the Hadhramaut in one direction and between Oman and Najran in the other, the actual denizens of the area—the Badawin tribes—are perfectly familiar with the term and use it in two senses, the one more comprehensive and vague than the other but both definitely geographical in import and contrasting with such descriptive terms as Madhma1 (land of thirst) and Mahmal1 (bare region). Apart from the fact that the Badawin have a limited application of the term—this was perhaps not appreciated before—as well as its common and wider connotation, my view as here stated accords with the traditional acceptation of the name * Rub* al Khali * both in Arabia and beyond its 1 These terms, as applied to the Empty Quarter and similar wastes, are more often used in the plural forms Madhami and Mahcaml, but excep- tions are frequent and the latter word is also used geographically, e.g. Mahmal (a district in Central Najd), Hand (part of Jafura) and Maham.il (desert between Wadi Dawasir and Bisha). 127
