Drawing of Samples 



Between April 1 and June 14, three sampling agents made a thorough can- 

 vass of the state: Louis A. Graves in Hampshire, Hampden, Franklin and 

 Berkshire 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 191 towns, took 1,697 samples, representing 

 494 brands, from stock in- the possession of 480 agents or owners, and called 

 upon 356 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 19,246 sacks, representing 16,486 

 tons of fertilizer. One ton was sampled to every four and one-half tons sold 

 in the state. 



COMPARATIVE COST OF FERTILIZER CHEMICALS AND 

 UNMIXED FERTILIZER PRODUCTS 



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

 moderate advance in price during 1937. Nitrate of potash has shown a marked 

 increase in price over the preceding year and, most likely due to war condi- 

 tions in Spain and in China, the salt has been largely absorbed by munition 

 manufacturers so that its present price almost prohibits its use as a fertilizer. 



Cyanamid and urea continue to be the cheapest source of organic nitrogen, 

 the former showing a constant advance in price and the latter a $6.00 decline 

 in price. However, on September 27, the quotations for synthetic urea had 

 increased to about the same as for the six months' average for 1936. 



Organic animal ammoniates, dry ground fish, cottonseed meal, and castor 

 pomace have all registered an increase for the six months ending March 1, 1937 

 as compared with average quotations for a like period in 1936. It should be 

 noted, however, that quotations on dried blood, tankage, and cottonseed meal 

 for September 27 show a considerable decline in price over the six months' 

 average.
