INTRODUCTION. 
The Fayum *, the lake province of Egypt, is a district occupying a depression in 
the desert to the west of tlie Nile Valley opposite Wasta, a small town about 
fifty-seven miles south of Cairo. This depression, which is roughly circular in 
outline, is separated from the river-valley by a belt of desert varying in width from 
about a mile and a half to some six or seven miles, and crossed at one point by a 
canal, the Bahr-el-Yusef, which runs through a narrow strip of low ground and is 
practically the only source of water-supply for the Avhole district. The water thus 
brouglit in from the Nile is distributed by irrigation-canals to the cultivated part of 
the district, and the surplus eventually finds its way through a number of channels, 
some of which form picturesque gorges, to the lowest part of the de])ression, 
occupied by a large expanse of brackish water, the Birket-el-Qurun. This lake is 
about twenty-five miles long, with a maximum width of only six miles ; it is very 
shallow, the maximum depth at present being about sixteen or seventeen feet, and its 
shores in most places are very low and gently sloping. In Pleistocene times the 
floor of the depression was occupied by a body of water of vastly greater area than 
the present lake, evidences of its former extent being found in the widely spread 
lacustrine deposits, chiefly clays, containing, in addition to numerous Mollusea, 
remains of Elephas africanus. Hippopotamus, Buhalis, Canis, together with those of 
Crocodiles, Chelonians, and Fishes (8) f. In one or two places also numerous
