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 Berkshire 

 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 157 towns, took 1,725 samples, representing 450 brands, from stock 

 in the possession of 425 agents or owners, and called at 320 places where 

 no samples were drawn because the agency had been discontinued, the stock was 

 all sold out, or sufficient samples had alread}' been taken of the brands found. 

 They sampled 22,972 sacks, representing 13,264 tons of fertilizer. One ton was 

 sampled to every four and nine-tenths tons sold in the state.
