The market value of low priced materials used for manurial pur- 

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

 factory refuse and waste materials of different description, quite 

 frequently does not stand in a close relation to the current market 

 value of the amount of essential articles of plant food they contain. 

 Their cost varies in different localities. Local facilities for cheap 

 transportation and more or less advantageous mechanical conditions 

 for a speedy action, exert as a rule, a decided influence on their sell 

 ing price. 



The market value of fertilizing ingredients like other merchandise 

 is liable to changes during the season. The above stated values 

 are based on the condition of the fertilizer market in centers of dis- 

 tribution in New England, during the six months preceding March 

 1897.
