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 compounds cost more than in 1899; other 

 materials were practically the same in price as in the previous year.
