90 THE MARKETING OF WHOLE MILK 



"(4) Less theft; 



"(5) Better working conditions for horses and drivers; 



"(6) Facilitates municipal supervision." 



The size of the load varies widely. It is to some extent 

 limited by what a man can deliver and to some extent by 

 other factors, such as length of route, whether customers 

 are scattered or grouped; whether each takes a large or a 

 small quantity; the amount of collecting done by the 

 driver; and the amount of double tracking which he finds 

 necessary. 



Frequently the size of load is surprisingly small. In 

 New York, for example, the Mayor's Committee estimated 

 the average load of retail wagons at 142 quarts, whereas 

 a theoretical maximum was said to be 428 quarts. 1 The 

 Department of Agriculture in 1915 reported the average 

 loads for five cities as follows:

 Average Loads for Five Cities, 1915 



Another factor which often keeps down the size of load 

 is the fact that every progressive dealer is planning on 

 an increase in business. When the size of load reaches 

 its maximum, he is likely to re-route in such a way as to 

 give each driver further room for expansion, thus building 

 up the business.
