FERTILIZER INSPECTION. 



Chas. D. Woods, Director. 



J. M. Bartlett, Chemist in charge of Inspection Analyses. 



The law regulating the sale of commercial fertilizers in this 

 State calls for two bulletins each year. The first of these 

 contains the analyses of the samples received from the manu- 

 facturer guaranteed to represent, within reasonable limits, the 

 goods to be placed upon the market later. The second bulletin 

 contains the analyses of the samples collected in the open market 

 by a representative of the Station. 



The analyses of the manufacturers' samples for this year 

 were published in March. A number of samples were received 

 so late that the analyses could not be included in the bulletin 

 then issued. The results of these analyses are given in the 

 tables on page 194. 



In the tables that immediately follow, the analyses of the 

 samples of commercial fertilizers collected in the open market in 

 the spring of 1906 by the Station representative are given. As 

 far as possible two samples of each brand were taken, an effort 

 being made to get the duplicate from a distinct lot of the same 

 brand in a different part of the State. For the most part the 

 samples were taken in the large warehouses where a large 

 amount of the goods were stored as received from the factory. 

 They were taken in almost every instance from a large number 

 of packages and in the presence of a representative of the manu- 

 facturers. The law requires that a duplicate sample be left 

 with the dealer or agent for the use of the manufacturer in case 

 the accuracy of the Station analysis is questioned. As this 

 .duplicate sample has been used only twice by the manufacturers 

 in the past ten years they, with the understanding that they 

 could have a portion of the Station sample if they should wish 

 for it, kindly waived their right to the reserve sample for the 

 present year. This is a saving in the time of the inspector and 

 in the number of sampling jars that he needs to take with him.
