The above trade values are the figures at which in the six months 

 preceding March 1888, the respective ingredients could be bought at 

 retail for cash in our large markets, in the raw materials which are the 

 regular source of sui)ply. 



They also correspond to the average wholesale prices for the six 

 months ending March 1st plus about 20 per cent, in case of goods 

 for which we have wholesale quotations. The valuations obtained 

 by use of the above figures will be found to agree fairly with the rea- 

 sonable retail price at the large markets of standard raw materials 

 such as : 



Sulphate of Ammonia, Dry Ground Fish, 



Niti'ate of Soda, Azotin, 



Muriate of Potash, Ammonite, 



Sulphate of Potash, Castor Pomace, 



Dried Blood, Bono and Tankage, 



Dried Ground Meat, Plain Superphosphates.
