refer to the suggestions in the seventeenth report of the Bureau 

 of Animal Industry at Washington, as an illustration of the official 

 view of this matter in the United States.^ 



made to satisfy even the most elementary hygienic requirements. On the other 

 hand, there are a great number of existing cowsheds which, although not fulfil- 

 ling all the conditions set forth above, may yet be rendered workable by provid- 

 ing them with abundance of light, efficient ventilation, impervious flooring, and 

 an adequate supply of water. These essentials CAN be secured, and should be 

 insisted upon by the Sanitary Authority. 



///. Register. 



A Register should be kept by every Sanitary Authority in which to record 

 the results of periodical inspections. No cowshed should be used for housing 

 a greater number of cows than is specified on the register. Amongst other 

 information locally desirable the following items are suggested : — 



1. Name and address of person registered. 



2. Situation of premises. 



3. Owner of premises. 



4. Number of sheds — with size, length, width, height, and cubic space per 



cow. 



5. Number of cows in each shed. 



6. Flooring — material and condition of. 



7. Walls, material — rough or smooth. 



8. Water supply — source, position. 



q. Lighting — number and size of windows or other lights. 



10. Ventilation — number and size of permanent openings. Number and 



size of openings capable of regulation. 



11. Midden — distance from cowshed, open or covered, disposal of liquid 



manure. 



12. Yard — formation, paving, drainage. 



13. Cleanliness — general condition of floors, walls, midden, yard. 



14. General drainage system. 



15. Disposal of drainage.

 subject which appear in Public Health, vol. xii., 1900, pp. 775-792. ("The Best 

 Means of Housing Cows," by John Speir.) 



^ "The stable shall be arranged with a view to the comfort of the animals, 

 and so as to facilitate the work of cleaning, milking, etc. 



"The floor shall be smooth and incapable of absorbing liquids, and sloping 

 sufficiently to cause good drainage. 



"The gutters behind the cows shall be open and with sufficient incline to 

 cause good drainage. 



"The side walls and ceiling shall be so tight as to prevent dust sifting 

 through, and they shall be so constructed as to prevent cobwebs and dust from 

 collecting, and easily to be cleaned. 



" There shall be windows in at least two sides of the stable, providing not less 

 than 3 square feet of unobstructed window glass to each animal.
