236 THE EMPTY QUARTER favourable seasons to wander to a distance of four or five days' journey from Shanna, Ziqirt and Naifa in search of pas- tures for their animals and Oryx or Rim gazelles for the pot. But in such cases they would always return in due course (when their camels needed water) to their base-wells and would thus never have occasion to penetrate further afield into the inhospitable desert. Similarly, as they well knew, hunting parties frequently enough visited the heart of the waterless desert from the Aflaj and Dawasir districts to shoot Oryx for ultimate sale in their home markets, where the flesh of the unicorn is considered a great and invigorating delicacy. Indeed a complete carcase, properly cured by drying in sun and wind, might well fetch prices as high as LlO, or even L20 in a season of scarcity. Such parties would, however, inevitably return from the hunting-grounds to their familiar waterings and would never want to visit Shanna or other such desert wells even if they could locate them. Suwid had penetrated from Sulaiyil with such parties to the districts of Al Jalada (Jilida) and Raida on more than one occasion, while Salim knew the Oryx grounds southwards of Wadi Dawasir towards Najran and had crossed the northern fringes of the waterless desert between Maqainama and the Afiaj district and from Bir Fadhil direct to Sulaiyil. Indeed, as they declared, only the more adventurous of the Murra Arabs—men like 'AH Jahman, Hamad ibn Sultan, Ibn Nifl, Ibn Fasl and some others—would go forth hunting in these generally rainless and pastureless districts, while any raiding party that might have occasion to traverse them in any direction would of necessity skirt the desert fringe and keep within reasonable reach of the borderland waterings in order to call at them in case of need. There was thus obviously no useful object to be served under the normal conditions of Arab life by a direct crossing of this vast waterless wilderness from side to side and, though it was and is perhaps difficult to believe that such a crossing had never been attempted or accomplished before just for fun or from sheer love of adventure, I can only place on record the fact that neither from my own companions nor from anyone that we met at Sulaiyil or elsewhere could I learn of any such attempt or achievement. It is therefore possible, and perhaps
