and productiveness greatly increased by feed- 

 ing the proper plant food. Study the wants of 

 your plants and supply the necessary manures. 

 The plant itself will plainly indicate what its 

 requirements are to the observing gardener, 

 and a soil analysis is not necessary. The follow- 

 ing compositions of plant food are in general 

 use: 



Nitrogenous manures are composed of dried 

 blood tankage, bone meal, nitrate of soda, sulphate 

 of ammonia. 



Phosphate manures, tankage bone meal, 

 super-phosphates, basic slag. 



Potash manure, muriate-potash, sulphate of 

 potash, kainit, wood ashes.
