The small tributary called =Wadi Abu Hashim=, which enters Wadi Garara from the south in about longitude 34° 5′, is important as containing the important wells known as =Bir Abu Hashim=. The wells are excavations in the alluvium of the wadi floor, and furnish good water at a depth of about eight metres. A beacon has been erected on a high hill to the west of the wells and overlooking them, the position of which is latitude 23° 41′ 44″ N., longitude 34° 3′ 33″ E., altitude 386 metres above sea and sixty-six metres above the wells. The principal roads from Bir Abu Hashim are, to Aswân (first water at Um Hibal, nearly one hundred kilometres distant), to Daraw (first water at Bir Qoleib, seventy-five kilometres distant), and to Abu Saafa Springs (a journey of about one hundred kilometres with possibly water en route at the Galt el Aguz, sixty kilometres from Abu Hashim). =Wadi Natash= commences among the low hills forming the Nile — Red Sea watershed between Gebel Migif and Gebel Abu Had. It pursues a course roughly parallel with that of Wadi Shait, at first over a sandy plain from which rise the two conspicuous cones called El Nahud (the breasts), and afterwards narrowing in among hills. Pursuing a somewhat devious course in a direction generally a little south of west, Wadi Natash passes south of Gebel Nugra (in longitude 33° 40′) and enters on the great plain called Atmur Nugra, where it joins the Wadi Kharit and drains to the Nile near Kom Ombo. There is, I believe, no water source in Wadi Natash itself, but =Bir Masur= is situated in a branch wadi only a few kilometres north of it in longitude 34°. At Bir Masur there are numerous pits sunk in the alluvium of the wadi, in one or more of which good water can generally be found at a depth of about ten metres; but the supply cannot always be relied on, for although I obtained plenty of water in March 1906, I found there was only a very small quantity available in October of the same year.
