Experience tells us that a liberal manuring pays better 

 than a scant one; yet, if we should try to restore to the soil 

 from outside sources a corresponding amount of all the fer- 

 tilizing constituents which the grass crop abstracts, it would 

 make, in most instances, there munerativc production of the 

 hay crop rather an exception than the rule. 



Good economy advises us to manure our lands with a par- 

 ticular reference to special wants. To do this intelligently 

 requires a fair knowledge regarding the following points : — 



1. The general character of the soil, the location of the 

 lands, the history of their former treatment, as far as the
