CITY MILK PLANTS: CONSTRUCTION AND ARRANGEMENT. 383 
The milk plant frequently can operate a laundry to advantage, 
especially if the men’s white working suits are washed by the plant. 
If cleaned at the milk plant’s expense the men will be more likely to 
change them often. 
Aside from the general toilet facilities it is advisable to have a 
washbowl, with soap and towels handy, in the milk-handling room. 
Employees in the handling room often get their hands dirty from 
setting up machinery, handling bottles, cases, etc., and it is essential 
to have a convenient place for them to wash their hands before 
handling sterilized bottles or engaging in other operations concern- 
ing milk, 
Milk apparatus should be covered so as to expose the milk to air 
as little as possible. This caution refers especially to vats, coolers, 
and bottling machines. 
Those dealers who have a hyeticee large enough to warrant the 
maintenance of a laboratory for the careful supervision of the 
quality of milk are in a much better position to safeguard the milk 
which goes out from their plants. 
COST OF PLANT. 
The amount of money that must be invested in a milk plant depends 
primarily upon the volume of business to be carried on. Whether 
it is desirable to erect an expensive building depends on local condi- 
tions. To give some idea of the cost, Table 8 has been compiled to 
show the investment in building at 84 representative milk plants of 
different sizes. In some cases if sufficient capital is not available it 
may be desirable to rent a building for a time rather than build a 
new plant, but if a new one is built it is advisable to erect a 
permanent, sanitary building of modern construction. While the 
first cost may be high, the permanent nature of the building will 
make the actual overhead expense for depreciation relatively small.
