CITY MILK PLANTS: CONSTRUCTION AND ARRANGEMENT. Padt 
- Drivers’? room.—A room connected with the office should be pro- 
vided in which drivers can score their books on returning from the 
routes. Bath and toilet facilities also should be provided for the 
drivers and men. 
Laboratory.—A. laboratory for the bacteriological and chemical 
examination of milk is essential for all plants. Small plants need 
only a small laboratory, while large ones require a complete labora-

however, one or more separate rooms are required for the by-products 
department. 
SIZE OF ROOMS. 
Each room in the plant should be large enough to avoid crowding 
the machinery or workmen, but at the same time there should be no 
unused space, for that causes extra labor in getting from one piece of 
apparatus to another. 
There is a wide variation in the size et the various rooms in milk 
plants, as well as in floor area per 100 gallons of bottled milk handled 
daily. These variations are due in a large measure to the lack of 
standardization of milk plants and to the fact that many have been 
constructed without consideration of important factors bearing on - 
the size of rooms.
