18 BULLETIN 639, U. S. DEPARTMENT OF AGRICULTURE. 
August 1, 1915, three months after the pasteurization ordinance 
became sifocnye. hens 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.) 
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 ca aprak ae 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
