1. Analyses of Materials forwarded for 

 Examination. 



We have received 257 samples of miscellaneous sub- 

 stances, during the season, from farmers within our State. 

 As far as circumstances and time permit we have taken up 

 these materials for analysis, and as a general thing have re- 

 ported results in the order of their arrival at this office. As 

 in the past, we have been obliged to neglect this class of 

 work until a lull occurred in the official inspection of com- 

 mercial fertilizers. From December to April we have most 

 time to devote to the investigation of general material, and 

 for this reason would prefer to have the samples forwarded 

 whenever possible, so they may be taken up during these 

 months. This would insure more prompt reports of the 

 results of analyses. 



We have taken the usual active part in the technical 

 chemical work of the Association of Official Agricultural 

 Chemists for the establishment of new methods of chemical 

 analysis, more particularly in regard to fertilizer work and 

 the analysis of insecticides. We have also been in co- 

 operation with the American Chemical Society and the 

 United States Geological Survey in regard to technical de- 

 tails in the chemical analysis of argillaceous limestone. The 

 results of these analyses were sent to the respective parties 

 in Washington.
