 speedy return of results of analyses to take advantage of this 

 fact, and send samples for analysis before the beginning of 

 our inspection season. 



During the year we have been in co-operation with the 

 Association of Official Agricultural Chemists, studying new 

 methods of analyses of soils, fertilizers and insecticides. 

 This is a very important part of the practical chemists' 

 work, and time should be taken every year for this co-opera- 

 tive investigation. 



The year has seen some new developments along the line 

 of producing valuable agricultural compounds for fertiliz- 

 ing purposes. These developments have naturally inclined
