FERTILIZER INSPECTION. 



Chas. D. Woods, Director. 



J. M. Bartle;tt, Chemist in charge of Fertilizer Analysis. 



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 i68 beyond the analyses of the Station samples. 



In the tables that immediately follow, the analyses of the 

 samples of commercial fertilizers collected in the open market in 

 the spring of 1905 by the Station representative are given. 



The samples were drawn by an experienced chemist and every 

 precaution was taken to make sure that they fairly represented 

 the goods sampled. So far as posible 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 manufacturers. 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, waived their right 

 to the reserve sample for the present year. This is a saving in
