CITY MILK PLANTS: CONSTRUCTION AND ARRANGEMENT. Le 
The size of the bottle-washing room depends somewhat on how the 
bottles are handled as they come from the delivery wagons. In 
case they have to be stacked in the wash room before being washed, 
a larger room will be required than if they pass directly from the

cause usually the bottles pass continuously through it. When there
