The above schedule of trade values was adopted by representa- 

 tives of the Massachusetts, Connecticut, Rhode Island, Maine, Ver- 

 mont and New Jersey Experiment Stations at a conference held dur- 

 ing the month of March, 1904, and is based upon the condition of 

 the fertilizer market in centers of distribution in New England, New 

 York and New Jersey during the six months preceding March, 1904, 

 and refers to the current market prices, in ton lots, of the leading 

 standard raw materials, which furnish nitrogen, phosphoric acid and 

 potash, and which enter largely into the manufacture of our com- 

 mercial fertilizers.
