The Topograph}' of Egypt between 28° and 30° N. L., from orig- 

 inal surveys made in 1882 and 1883, with special reference to 

 the erosions — 200 feet — of the Qerunand Reian Basins, and 

 the two natural eminences ( + 650), to the west of the Kom

 pyramids of Gizeh. 



[Abstract.] 



On March 3, 1882, I went into the desert about fifty miles west of 

 the Nile Valley and seventy-five miles southwest of Cairo, to examine 

 the neighborhood of a hill, hitherto unvisited, known to the Arabs as 

 the Haram. " Haram " is " Pyramid." This hill is not a pyramid 

 nor is it pyramidal in appearance, although the buttes of horizontal 

 limestone commonly assume a conical form. Nor is there any pyra- 

 mid in Egypt (with one insignificant exception) to the south of the 

 point where the Bahr Jousuf, which branches from the Nile at Siut, 

 turns into that Western Oasis which has been identified with Pithom 

 and the land of Goshen. Being without any European servant or com- 

 panion, I could only satisfy myself that this hill of limestone streaked 

 with gypsum was in a valley considerably below the level of the Nile. 

 On April 4, 1 visited the Eastern part, and Mr. Flinders Petrie, who 

 accompanied me, assured me that it was not less than 250 feet below 

 the level of the Nile, or about 180 feet below the Mediterranean. If 

 filled with water, it would have the shape shown on the accompanying 

 maps. This valley is not marked on any map prior to my auto- 

 graph map, published in the June Proceedings of the Society of Bibli- 

 cal Archaeology (1882). My belief in its existence was due to the 

 ancient records of a Lake Moeris containing a pyramid-island, and a 

 mu ajHcnti nti mar, " the water of the lake of the West," with a canal 

 ascribed by tradition to the patriarch Joseph or to a King Men. The 

 lake or Birket marked on the map in the northern half of the same 

 depression is stated in the books as about the level of the Mediterra- 

 nean. On March 12, 1883, I ran a line of levels, aided by an Italian 

 engineer, M. Gasperoni, with instruments furnished by the Cadastre, 

 between the highest level of recent alluvial deposit and the lake. It
