ANALYSIS. 227 



While waiting for its further instruction, let us make 

 the best possible use of what chemistry now teaches 

 vnth certainty, in the analysis of the ashes of plants, 

 and of manures. 



Practice and science have combined to show ti3 

 how all soils may be raised to a high, possibly to the 

 highest, state of fertility, and a knowledge of the 

 composition of crops and manures shows how we 

 may best maintain its good condition. 



The one safe rule for all farmers to adopt is the 

 following : — 



Always ketuen in the earthy constituents of 

 manure the full equivalent of the eaethy con- 



BTITUENTS OF THE CEOP. 



This will prevent the soil from deteriorating, and 

 we may safely trust to the process of cultivation, and 

 to the action of atmospheric influences, to make it 

 yearly better, by developing fresh supplies of its ash- 

 formin^r parts.
