From the means of ten samples of soil from Kena Mudirieh analysed 
for me in May by Mr. Frank Hughes of the Agricultural Society we 
gather that the constituents of the soil are as follows : —

We have here a general sufficiency of phosphoric acid, plenty of 
potash and lime, and a low proportion of nitrogen. 
The salts of the soil, when in excess, are chlorides and sulphates of 
soda : the carbonates are present in very small quantities indeed. 
The following selection from a paper by Mr. Lang Anderson in 
the December 1903 number of the Journal of the Khedivial Agricul- 
tural Society is interesting.
