50 EXPERIMENT STATION. [Jan. 



The total number of samples collected was 1,042, represent- 

 ing 458 distinct brands, — being 418 more samples than during 

 the preceding year. Wherever possible an analysis has been 

 made of a composite made up of equal weights of the same brand 

 collected in various parts of the State. Samples have been 

 taken with the usual care and discrimination, the collecting 

 agents being instructed to sample at least 10 per cent, of the 

 number of packages of each brand, and never less than five 

 bags, without making a special note of the fact on the guarantee 

 slip which is sent to the laboratory with each sample taken. 



(c) Fertilizers analyzed. 

 The following analyses have been made in connection with 

 the inspection of licensed fertilizers : — 



Comi>lete fertilizers, ........ 384 



Ground bone, tankage and tisli, ..... 61 



Materials furnishing' phosphoric acid, potash and lime, 



such as ashes, ........ 16 



Nitrogen compounds, such as nitrate of soda, sulfate of 

 ammonia, blood, castor i^omace, cottonseed meal and 



linseed meal, ........ 68 



Potash compounds, ........ 34 



Phosphoric acid compounds, ...... 17 



In addition to the above, 33 samples of fertilizer have been 

 analyzed that were not licensed but which were goods manu- 

 factured for private use. These goods were sampled officially 

 by our collecting agents from stock in the possession of the 

 consumer. This makes a total of 613 analyses which have been 

 made during the season of 1909. 



In some instances, where the results of analysis of a coui- 

 ])osite sam])le showeij a l)rand to be seriously deficieut in plant 

 food, a new sample has been prepared for analysis from each 

 original sample taken, and separate analyses have been made. 

 This was done to ascertain if the shortage was general, or con- 

 fined to one or more lots of the same brand. Thirty-five such 

 com])lete analyses were made during the season from 13 com- 

 posite samples; 172 more analyses have been made than during 

 the previous year.
