112 MASS. EXPERIMENT STATION BULLETIN 169. 



Selling ability depends upon a great many things — a knowledge of 

 general crop conditions, of marketing conditions, of current price quota- 

 tions, of the onion supply in and out of storage, of the requirements of the 

 market as to standard packing and grading, and upon ability to bargain. 



All these are effective selling arguments for the producer. Again, such 

 knowledge must help the farmer in deciding when is the best time to sell . 

 One must always keep in mind that a crop sold from 10 to 20 cents a bag 

 less than the normal market price means a decided curtailment of the 

 producer's income. 



In Fig. 36 an attempt is made to show the spread between the price 

 to the farmer, the wholesale price and the consumer's price.
