WORK IN CONNECTION WITH BERSIM IN 1915. 



Berslm is the general term applied to four varieties of clover 

 included under the specified name of Trifolium alexandrinum, a plant 

 apparently of Egyptian origin and, as far as is at present known, 

 peculiar in the richness of its crops, which are taken in the winter and 

 throughout the spring. 



Small plots of the four varieties, Ba'li, Fahl, Khadrdwi, and 

 Misqawi, were sown in November 1914 in order to ascertain the 

 characteristic differences of each. 



Fahl was found to exhibit a remarkably different appearance from 

 the three others when planted with them and is readily recognized 

 on account of its quicker and more luxuriant growth. Misqawi 

 and KJiadrdwi have many common characteristics, and are rather 

 better in growth than Ba'li, but they do not approach the same 

 standard as the Fahl variety. 



For determining the respective yields an area of four square 

 metres was measured off in the centre of each of the twelve plots of 

 the four varieties. The bersim from the known area was cut by hand 

 and weighed, the yields being as follows :

The forty- eight plots were arranged in chess-board fashion in 

 order to eliminate any irregularities in the soil. 



The following table shows the results of the observations which 

 were taken on the height and leaves of the plant.
