BULLETIN 639, U. S. DEPARTMENT OF AGRICULTURE. 



August 1, 1915, three months after the pasteurization ordinance 

 became effective, there were 68 plants in which milk was prepared for 

 market distribution. Approximately 75 per cent of the total milk 

 supply was pasteurized by 11 dealers whose average daily output per 

 plant was more than 3,600 gallons. About 10 per cent of the city's 

 milk supply was distributed by small dealers who purchased their 

 supplies from other dealers who operated pasteurizing plants. (See 

 fig. 7.) 



CAPITAL INVESTED AND COST OF HANDLING MILK AT CITY PLANTS. 



To show the investments required for milk plants and equipment, 

 and the varying costs of handling milk in preparing it for distribu- 

 tion in the city, the records of 28 representative dealers were obtained. 

 Table XIII shows the varying investments in relation to the operat- 

 ing costs in the plants, according to increasing costs of handling.

1 These unit costs include charges for depreciation and interest on capital invested, supplies, and labor 

 expenses (all the items which could be definitely charged against handling in plant). 



2 Supplies include charges for fuel, ice, power and light, bottles, caps, washing powder, brushes, etc. 



A study of the table reveals rather wide variations in the costs of 

 handling milk in the different plants, many of which are caused by 

 the varying proportions of bottled and bulk milk handled. The
