New York AGRICULTURAL EXPERIMENT STATION. 441 
TRADE-VALUES OF PLANT-FOOD BLEMENTS IN RAW MATERIALS AND 
CHEMICALS. 
The trade-values in the following schedule have been agreed 
upon by the Experiment Stations of Massachusetts, Rhode Island, 
Connecticut, New York, New Jersey and Vermont, as a result of 
study of the prices actually prevailing in the large markets of 
these states. 
These trade-values represent, as nearly as can be estimated, 
the average prices at which, during the six months preceding 
March, 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 phos- 
phoric acid) to the average wholesale prices for the six months 
preceding March plus about 20 per ct. in case of goods for which 
there are wholesale quotations.
