poses, as salt, wood ashes, various kinds of lime, barnyard manure, 

 factory refuse and waste materials of different descrii)tion, does, 

 quite frequently, not stand in a close relation to their chemical com- 

 position. Their cost varies in different localities. Local facilities 

 for cheap transportation and more or less advantageous mechanical 

 condition for a speedy action, exert, as a rule, a decided influence on 

 their selling-price. 



The wholesale market price of manurial substances is liable to 

 serious flactatious ; for supply and demand exert here, as well as in 

 other branches of commercial industry, a controlling influence on theii 

 temporary money value. As farmers have only in exceptional in- 

 stances, a desirable chance to inforfia themselves" regarding the con- 

 ditions which control the market price, the assistance rendered in 

 this direction, by Agricultural chemists charged with the examination 

 of commercial fertilizers, cannot otherwise but benefit, ultimately 

 both farmers and manufacturers. 



The market reports of centres of trade in New England, New York 

 and New Jersey, aside from consultations with leading manufacturers 

 of fertilizers furnish us the necessary information regarding the cur- 

 rent trade value of fertilizing ingredients. The subsequent state- 

 ment of cash-values in the retail trade is obtained by taking the 

 average of the wholesale quotations in New York and Boston, during 

 the six months preceding March 1, 1887, and increasing tiiem by 20 

 per cent., to cover expenses for sales, credits, etc. 



These trade values, except those for phosphoric acid, soluble in 

 ammonium-citrate, were agreed upon by the Itxperiment Stations of 

 Massachusetts, Connecticut and New Jersey for use in their several 

 states for the present season.
