FIG. 4. SYSTEMS OF MILK SUPPLY 



Upper figure: simple or undeveloped state, small communities. Each 

 dairyman retails his own supply, sometimes drawing from his neigh- 

 bors. Lower figure: developed state, under city conditions. Milk 

 depots for centralizing such operations as collection, pasteurizing, 

 bottling, and transferring milk by wholesale are in this case an 

 economic necessity. In many communities a mixture of the two 

 systems exists.
