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 includes such fixed charges as cost of mixing, bags, 

 cartage, and freight, salaries and commissions of agents, and 

 interest. 



Nitrogen in the best animal fertilizers and in nitrates cost 

 more in 1902 than in the previous year. Other prices were 

 unchanged.
