The above values are based on the wholesale market price 

 for the materials, when sold in large lots at the principal trade 

 centers in New England. The valuation of a ton of any 

 mixed fertilizer based on the above figures will usually fall ten 

 dollars below the retail price at the local agency. This varia- 

 tion includes such fixed charges as cost of mixing, bags, cart- 

 age and freight, salaries and commissions of agents and inter- 

 est. 



A sharp advance in the price of mixed fertilizers was made 

 this year, due mainly to the advance in the price of nitrate of 

 soda and animal matter.
