cents a pound for water-soluble phosphoric acid, 4 cents a pound

 late the commercial valuation, or the price at which the separate 

 unmixed materials contained in one ton of fertilizer, having the 

 composition indicated in the preceding table, could be purchased 

 for cash at retail at the seaboard. Knowing the retail prices at 

 which these goods were offered for sale, we can also readily esti-

 goods and the retail cash cost of the unmixed materials; the differ- 

 ence covers the cost of mixing, freight, profits, etc. We present 

 these data in the following tables:
