the inspectors have been instructed to sample at least 10 per- 

 cent of the whole lot of each brand inspected, and never to 

 sample less than 5 bags without making a special note of the 

 fact on the guarantee slip which is sent to the laboratory with 

 each sample taken. 



Fertilizers The following analyses have been made in connec- 

 Analyzed. tion with the inspection of licensed fertilizers: 



Analyses. 



Complete fertilizers 384 



Ground bones, tankages and fish . . 61

These analyses have been grouped in the tables which follow 

 in the order above given, and arranged alphabetically according 

 to manufacturers' names. In addition to the above, 33 ferti- 

 lizers have been collected and analyzed that were not licensed 

 but which were manufactured for private use. The analyses 

 of these brands appear in a table by themselves immediately 

 following the tables of mixed licensed fertihzers, and just pre- 

 vious to the tables giving analyses of ground bones. 



A total of 613 separate analyses were made in connection 

 with the inspection of 1909. Whenever possible an analysis has 

 been made of a composite composed of equal weights of distinct 

 samples of the same brand, collected in various parts of the state. 

 In instances where the results of analysis of a composite have 

 shown a brand to be seriously deficient in one or more plant 

 food elements, a new sample has been drawn for analysis from 

 each original sample taken and a separate analysis made. This 

 was done to ascertain if the shortage was general or confined to 

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

 analyses were made from thirteen composites. One hundred 

 and seventy-two more analyses have been made than during the 

 previous year.
