 nitrate of soda are sown as top dressings. 



The seed was dibbled in the earher years of the expcrinu'nt ; 

 it is now drilled, 26 inches between the rows, and the ])lants 

 are singled out to 10 inches apart. 



The following tables give, (XL.) the average weight of roots

A first inspection of the results shows the enormous value 

 of farmyard manure in growing mangels, especially when tliey 

 are grown continuously on the same land. In tavouiabh' 

 seasons it is possible to obtain good crops by ilie aid of 

 manures containing no organic matter, as seen in I'.MJU; l)ut
