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; G. E. Taylor in Norfolk, Bristol, Plymouth, Barnstable and 

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

 Counties. They visited 189 towns, took 1,667 samples, representing 479 

 brands, from stock in the possession of 516 agents or owners, and called upon 

 282 agents where no samples were drawn because the agency had been dis- 

 continued, the stock was all sold out, or sufficient samples had already been 

 taken of the brands found. They sampled 19,097 sacks, representing 13,935 

 tons of fertilizer. One ton was sampled to every four and five-eighths tons sold 

 in the state. 



COMPARATIVE COST OF FERTILIZER CHEMICALS AND 

 UNMIXED FERTILIZER PRODUCTS. 



Ammonium sulfate, nitrate of soda and calcium nitrate have either shown 

 but little change or have shown a slight decline in price for the six-month 

 period ending March 1. During the early fall the price of each has somewhat 

 strengthened. Nitrate of potash for the six months ending March 1, 1936, 

 showed a decline in price of $2.25 per ton as compared with the same period 

 in 1935. 



Organic animal ammoniates and dry ground fish have shown an appreciable 

 advance in price during the season. On the other hand, synthetic urea, cotton- 

 seed meal and castor pomace have shown a decline, but for the organic vege- 

 table products the price has increased as the season has advanced. 



Superphosphate has shown a consistent decline in price during the season 

 and was quoted 50 cents per ton lower on September 28, 1936, than for the 

 six months ending March 1, 1935. 



Potash salts did not vary materially in price during the six months ending 

 March 1, 1936, as compared with the same period for 1935. The September 

 28, 1936, quotations, however, show a consistent advance in price for all 

 potash salts used in fertilizers. 



This brief summary might indicate a slight advance in price of mixed com- 

 mercial fertilizers for the season of 1937.
