Mr. James T, Howard, our regular inspector, was in 

 Collection of charge of the fertilizer collection for the season. He 

 Fertilizers. was assisted by Mr. J. A. Cunningham and Mr. C. A. 

 Bradford. Most of the samples were procured be- 

 tween the dates of April 1st and May 29th. An effort was made to 

 procure representative samples of every brand of fertilizer and lime 

 registered in the state of Massachusetts. In the few cases where 

 representative samples were not found an invitation was given to 

 the manufacturer to send us a certified representative sample of the 

 brand. These will appear in the bulletin as manufacturer's samples. 

 Whenever possible duplicate samples have been procured of the same 

 brand taken in various parts of the state, and the custom has been 

 followed of making an analysis of the composite sample composed of 

 equal weights of the various samples taken in different localities. 

 This insures the obtaining of analytical data on a larger tonnage than 

 would be possible if only one sample of a brand were analyzed. From 

 data collected by our inspectors 7,437 tons of fertilizer were sampled. 

 To obtain adequate samples from this tonnage it was necessary to 

 sample about 18,750 different sacks. Of the complete fertilizers 

 sampled 69 per cent of the total tonnage were high grade fertilizers, 

 (valued over $24.00 a ton), 17 per cent were medium grade, (valued 

 between $18.00 and $24.00 a ton), and 14 per cent were low grade, 

 (valued less than $18.00 a ton). 



During the late fall and early winter large shipments of cotton- 

 seed meal, wood ashes and lime compounds are delivered to farmers 

 who buy these products early so as to move them more conveniently 

 before the rush of the spring work. It has been our custom, which 

 we hope to continue, to sample and analyze such shipments upon call, 

 simply making a nominal charge to cover the cost of procuring the 

 sample. Wherever a party desiring the analysis is located too far 

 from the experiment station to warrant sending an inspector to 

 sample the goods, a sampling tube will be sent by express together
