conditions. They have been repeated so as to eliminate as far 

 as possible the influence of outside factors. 



The first thing attempted was to settle the average quantity 

 of salts and their nature, compatible with such and such a 

 yield, and that in a sufficiently large number of localities differ- 

 ing amongst themselves as to soil, climate, etc., etc. 



Next the causes for certain differences ascertained to exist 

 between the north of the Delta and other parts of the country 

 were investigated. 



In another set of investigations an attempt was made to 

 ascertain exactly how the action of the salts affects the growth 

 of the plant and its products. 



These researches are not merely of academic interest. The 

 deductions derived from them are very valuable in a country 

 like Egypt, where the question of injurious salts is of supreme 

 importance from the point of view of the fertility of the soil. 



These data find a direct application in the development of 

 the Bararis. 



They have enabled us to discover the reason of the more or 

 less complete barrenness of certain districts, and have thus led 

 us to a rational method of treatment for such areas. 



Lastly, these results have frequently afforded an explanation 

 of certain anomalies observed in many manurial trials. 



The CHAIRMAN : Je remercie M. Mosseri pour sa contribution 

 tres importante et nous sommes surs qu'elle servira beaucoup 

 a mettre en valeur les regions larges et vastes en Egypte, aux- 

 quelles Lord Kitchener a refere ce matin.

 developing the wide and vast regions in Egypt to which Lord

The CHAIRMAN: We are much obliged to M. Fedtschenko 

 for his interesting contribution which deals with a question 

 of considerable importance for vast regions in other parts 

 of the world, chiefly Turkey. In Asia Minor, also, cotton is 

 grown without irrigation, and in places which have a rather
