IT is incumbent upon every gardener that he or she should have 

 at least an elementary knowledge of fertilizers; their necessity, 

 their composition and their use. Prof. Thos. H. White, in the 

 chapter which follows, has given in clear, concise form, this necessary 

 information and has also demonstrated the advisabihty of using 

 certain forms of fertilizers for defined purposes. We might add that 

 where well rotted stable manure is still available, it will fulfill nearly 

 all garden purposes on soil that has been kept in fair cultivation. For 

 limited areas we advise consultation with and direct purchase from 

 your seedman.

When considering the cultivation of plants it is highly important 

 that some thought be given to fertihzers. Some soils are naturally 

 fertile, others are very infertile and need judicious fertilizing. Trees 

 and shrubs will grow very well on soils that are moderately fertile, 

 but the soft, quick growing plants of the garden musthave very fertile 

 soil. This is especially true of all annual plants that are grown from 

 seed. The little seedlings, with their small, tender rootlets, must be 

 properly supplied with food before it is possible for them to make 

 rapid growth. 



Nearly everything that is in the air or on the earth suppHes some- 

 thing, either directly or indirectly, to the soil as fertilizer. All organic 

 substances, that is, substances which have or have had life, are of
