ANALYSES OF FERTILIZERS 



The samples of fertilizer for the 1909 inspection were 

 collected by Mr. A. J. Richardson, under the direction of 

 the State Board of Agriculture. Aside from duplicates, one 

 hundred and thirty-eight samples were taken. Nineteen of 

 these were taken from brands that were offered for sale but 

 were unh censed. These samples have not been analyzed and 

 the names and analyses do not appear in the following list. 



The number of l)rands of fertilizer offered for sale the 

 past year was the largest in the history of the state. If 

 agriculture is to continue in greater favor, the number of 

 brands will gradually increase. 



The following schedule of trade values was adopted for 

 the season of 1909 at a meeting of the station directors and 

 chemists for use in ]\Iaine, New Hampshire, Vermont, 

 Massachusetts, Connecticut, Rhode Island and New Jersey. 

 These values were made from quotations obtained by con- 

 sumers, and on the average are somewhat lower than the 

 values of the preceding year.
