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 Avith the usual care and discrimination, the collecting 

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

 number of ])ackages of each brand, and never less than five 

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

 slij) which is sent to the laboratory with each sample taken. 



(c) Fertilizers aiiali/zed. 

 The following analyses have been made in connection with 

 the inspection of licensed fertilizers : • — - 



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



Ground bone, tankaj>e and Hsh, ..... 61 



Materials furnishing pliosi>horic acid, potash and lime, 



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

 ammonia, blood, castor pomace, cottonseed meal and 



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



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



Phosphoric acid compounds, ...... 17 



In additiou to the above, 3o samples of fertilizer have been 

 analvzed that were not licensed but which were goods manu- 

 faetured for private use. These goods were sampled ofticially 

 by our collecting agents from stock in the possession of the 

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

 made durinc; the season of 1009. 



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

 posite sami)le showed a brand to be seriously deficient in plant 

 food, a new sample has Ix-en 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 oi" more lots of the same brand. Thii'ty-five such 

 coiiiplete analyses were made during the seasou from 1 -> com- 

 posite sitmjjles; 172 more analyses have been made than during 

 the previous year.
