ROOTS— CROPS C AND F. 



In the leaves aud stalks there is a great variation m the magnesia 

 content of crops A and C and F. Tliis difference, which holds for 

 all four plats, may be due either to different climatic conditions exist- 

 mg at the time of growth, or to the crops being cut at different stages 

 of growth, since this plant was grown for a certain nvmiber of days. 

 With bush beans sunilar differences were obtamed between the mag- 

 nesia content of crop B and the combined crops D and F. In this 

 case the difference in the magnesia coiild not have been due to the 

 crops being cut at different stages of development, since all the 

 crops of bush beans were harvested in flower. 



The average relative compositions of the three crops from the dif- 

 ferent plats are given in Table XXII.
