These trade viilues will be found to correspond fairly with 

 the average wholesale quotations of chemicals and raw materials 

 as found in trade publications for the six months preceding 

 March 1, plus about 20 per cent. They represent the average 

 pound cost for cash at retail of the various ingredients as fur- 

 nished by standard unmixed chemicals and raw materials in 

 large markets in New England and New York for the six 

 months ])receding March 1, 1910. The cost of the mineral 

 forms of nitrogen (nitrate of soda and sulfate of ammonia) has 

 been somewdiat lower than for the previous year, which has led 

 to a more general use of these forms of nitrogen. Nitrogen 

 from organic sources has been a cent higher than for the season 

 of 1909. The cost of phosphoric acid was one-half cent higher 

 than for the previous season. There was no material change 

 in the cost of the various forms of potash.
