SOME FACTS BEARING UPON IRRIGATION. 131 
At the meeting of the Mechanical Section of the British Associa- 
tion in 1882, John Fowler, Esq., C.E., F.G.S., the President of 
the Section, stated in his address “that the cultivated lands of 
Lower Egypt have an area of 3,000,000 acres, and to irrigate this 
effectually, at least 30,000,000 tons of water per day would be 
made at Ki near Euston, under the direction of the Engineer-in- 
Chief for Harbours and Rivers. Taking then these quantities, 
I find the average (six years) outflow of the river, that is, all the 
necessarily in lar 
very active, so that the river, even if all the water were taken out 
of 
the utmost, From this, a considerable reduction would have to 
made for loss in distribution ; by leakage, &c. Iam not opposed 
Urigation ; on the contrary, I think itis the want of the interior 
as itself to me is to find sufficient water for general irriga- 
on. . ;
