The total expenditure amounts to £6,000,000 spread over 12 years. 
The great advantage of undertaking all those works together may 
be thus summarized. The increased supply from the Assuan reservoir 
will be felt in Egypt after a period of two years. Five years later the 
waters of the Wady Rayan will be added to those of the Assuan 
reservoir, and it will be possible to increase the cotton crop of Egypt 
from 6 million to 10 million cwt. It will be possible to allow the 
Sudan to thoroughly develop its agricultural resources, and with the 
aid of the 25,000 horse power as a minimum which the 6th cataract 
near Khartoum can supply, to utilise for its own consumption the 
waters which can be stored at that cataract ; and, in addition to those, 
the available supplies from Lake Tsana provided that that lake is fur- 
nished with an outlet tunnel. 
While all this life and activity will be developing themselves in 
Egypt and the Sudan, the effects of the regulator of Lake Albert and 
the training of the Albert Nile in the Sudd regions will be gradually 
asserting themselves ; and, if the works are being steadily and 
perseveringly carried out, it is well within the range of possibility 
that before 10 or 12 years will have passed, the additional supplies 
from the upper waters of the White Nile will have become so ample, 
that it will be possible to dispense with the Wady Rayan as a reservoir. 
When this will have happened, the Wady Rayan with its canal will 
become the true flood escape of Egypt, like the ancient Lake Moeris, 
and will, with the Rosetta branch, afford complete protection to Egypt 
against the dangers of a high flood. Egypt, in the fullest meaning 
of the term, will be enjoying perennial irrigation and flood protection. 
In my book on the “ Assuan Reservoir and Lake Moeris ” I had 
recommended a more extended programme, but the reading of Sir 
William Garstin’s Report has convinced me that useful as the Lake 
Victoria reservoir dam may be, its postponement as recommended by 
Sir William is sound, until all the other works have been executed. 
The really essential work is the Lake Albert reservoir dam, of which 
the study might indeed be commenced immediately. Sir William’s 
proposal to train the summer supply of the Albert Nile and allow the 
overflow of the floods to find its way through the Sudd region is so 
sound and convincing that the necessary training works in the Sudd 
region are greatly reduced. With these reductions the estimated cost 
of the project for water storage and flood protection for Egypt is 
reduced from £8,200,000 to £6,000,000. I have left the Wady Rayan
