2. The farthest point that was reached to the south-west of Dakhla was practically the centre of the desert. This journey showed that the pre-existing ideas of this district were entirely wrong, and that the hundreds of thousands of square miles, shown in this part on the old maps as being covered with gigantic dunes, were in reality practically free from drift sand, and that the large dune-field lying to the west of the Egyptian frontier, that Rohlfs had found such an impassable obstruction, came to an end about a day’s march to the south of his route, the sand being all banked up by the high sandstone plateau that we found occupying the centre of the desert.[6]
3. The position of Bu Mungar hattia was astronomically fixed, and the cliff running from there to Dakhla was mapped for the first time.[7]
4. The cliff forming the eastern boundary of the Farafra depression was mapped, thus showing that the escarpment of the east and north of Kharga is a continuation of the cliff that runs west from Iddaila Oasis, the whole escarpment—except for a narrow break to the north of Farafra—is consequently continuous and runs for some 450 miles. It forms the southern limit of the limestone plateau, and is the main hill feature of this part of the desert.[7]
5. Two small new oases—’Ain el Agwa and ’Ain Khalif—were found in the western portion of the Farafra depression. The site of Bu Gerara was also discovered, and most of the isolated little plateau that lies on its south-west was mapped.[8]
6. A survey of the desert to the north of ’Ain Amur showed that the plateau there was riddled with a curious network of little depressions.[9]
7. Several months were spent in studying the sand dunes and their method of formation.[10]
8. A considerable amount of material was collected on the manners, customs, legends, measurements and superstitions of the natives.[11]
9. Notes were also made upon their methods of well sinking, and dividing the flow from the wells.[12]
10. Over 240 characters and inscriptions of the “Libyan” type were found and copied.
11. A number of plants growing in the desert and oases were collected and their geographical distribution worked out.[13]
