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 variation in- 

 cludes such fixed charges as cost of mixing, bags, cartage, and 

 freight, salaries and commissions of agents, and interest.
