the respective ingredients, in the form of unmixed raw materials, 
could be bought at retail for cash in our large markets. These 
prices also correspond (except in case of available phosphoric acid) 
to the average wholesale prices for the six months preceding 
March plus about 20 per cent in case of goods for which there are 
wholesale quotations.

COMPARISON OF SELLING PRICE AND COMMERCIAL VALUATION. 
Giving to the different constituents the values assigned in the 
schedule for mixed fertilizers, 14 cents a pound for nitrogen, 4 1-2 
eents a pound for water-soluble phosphoric acid, 4 cents a pound 
for citrate soluble phosphoric acid, 2 cents a pound for insoluble 
phosphoric acid, and 4 1-4 cents a pound for potash, we can calcu- 
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- 
mate the difference between the actual selling price or the mixed 
goods and the retail cash cost of the unmixed materials; the differ- 
ence covers the cost of mixing, freight, profits, ete. We present 
these data in the following table, including only complete fer- 
tilizers.
