MARKET MILK 157 



should be freely applied at least twice a year both to walls 

 and ceiling, as it helps to purify the stable and to keep it light. 

 An abundance of light is necessary ; 4 square feet of glass to a 

 cow is generally sufficient if the windows are well distributed 

 and not obstructed in any way. If the stable is located with 

 its length north and south, it receives the purifying benefit of 

 both the morning and afternoon sun. 



Every cow stable should have a system of ventilation to 

 keep the air fesh and pure and the cows comfortable without 

 exposing them to injurious drafts. If the smell in the stable 

 is disagreeable at any time, it indicates that the ventilation is

The principal purpose in building a milk-house is to provide

 vide the interior of the building into two or more rooms in 

 order to wash the utensils and handle the milk in separate 

 rooms. The milk-house and all its equipment should be so 

 planned that unnecessary steps will be avoided and labor 

 economized to the greatest extent. 



Thorough cleanliness must always be kept in mind ; there-
