The Stable. 



9. No stagnant water, hog-pen, privy or uncovered 

 cesspool or manure pit should be maintained within 100 

 feet of the cow stable. 



10. The cow stable should be provided with some ade- 

 quate means of ventilation, either by the construction of 

 sufficient air chutes extending from the room in which 

 the cows are kept to the outside air, or by the installation 

 of muslin stretched over the window openings. 



11. Windows should be installed in the cow barn to 

 provide sufficient light (2 sq. feet of window light to each 

 600 cubic feet of air space the minimum) and the win- 

 dow panes be washed and kept clean. 



12. There should be at least 600 cubic feet of air space 

 for each cow. 



13. Milch Cows should be kept in a place which is used 

 for no other purpose. 



14. Stable floors should be made water-tight, be prop- 

 erly graded and well drained, and be of some non-ab- 

 sorbent material. Cement or brick floors are the best x as 

 they can be more easily kept dean than those of wood 

 or earth. 



15. The feeding troughs and platforms should be well 

 lighted and kept clean at all times. 



16. The ceiling should be thoroughly swept down and 

 kept free from hanging straw, dirt and cobwebs. 



17. The ceiling must be so constructed that dust and 

 dirt therefrom shall not readily fall to the floor or into 

 the milk. If the space over the cows is used for storage 

 of hay, the ceiling should be made tight to prevent chaff 

 and dust from falling through. 



18. The walls and ledges should be thoroughly swept 

 down and kept free from dust, dirt, manure or cobwebs.
