First edition of Philby's most difficult to find titles, and one of the most important travel books on Central Arabia, written by a friend of Ibn Saud. Philby explored the lands between the Persian Gulf and Jeddah on the red sea, took very good photos and notes on the geography and the people he encountered. The resulting maps are the best of the period, including one of southern Nejd, with routes between Riyadh and Wadi Dawasir.
