The attention of planters has not vet been sufficiently 

 aroused as to the necessity of introducing magnesia into 

 manurial mixtures. We are of the opinion that in places 

 where there is an abundant rainfall the supplv of this element 

 is insufficient, especially when there is a seed crop in view. 



The particular demand we make of the Leguminos^e is 

 that they should fix atmospheric nitrogen and store it up 

 in the soil. Consequently, the more active the growth the 

 better will be the general development, and the better will 

 the plant perform its chief function, i.e., the fixation of 

 atmospheric nitrogen. 



It is impossible to pay too much attention to Leguminosce
