The following brands were not found on display by the sampling agent at any 

 point in the state and therefore do not appear in the tables of analyses. 



Brands of Fertilizers Registered but Not Sampled 



a Sales discontinued May 1, 1939. 



Drawing of Samples 



Between April 1 and June 15, three sampling agents made a thorough canvass 

 of the State: James T. Howard in Hampshire, Hampden, Franklin, and Berk- 

 shire Counties; L. A. Graves in Norfolk, Bristol, Plymouth, Barnstable, and 

 Dukes Counties; and C. L. Whiting in Essex. Middlesex, Suffolk, and Worcester 

 Counties. They visited 173 towns, took 1,818 samples, representing 519 brands, 

 from stock in the possession of 415 agents or owners, and called upon 305 agents 

 where no samples were drawn because the agency had been discontinued, the 

 stock was all sold out, or sufficient samples had already been taken of the brands 

 found. They sampled 23,602 sacks, representing 23,020 tons of fertilizer. One 

 ton was sampled to every two and four-fifths tons sold in the state. 



FERTILIZER TRADE VALUES 



The fertilizer trade values are based on average wholesale quotations of ferti- 

 lizer chemicals and unmixed materials, as taken from trade journals for six 

 months ending March 1, 1939, to which 20 per cent has been added for over- 

 head. When appropriate, an additional allowance has also been made for bags, 

 labor, and transportation.
