 and decaying animal or vegetable matter at all times.

 will be clean and sanitary at all times. 



20. Stables should be whitewashed at least twice a year, 

 unless the walls are painted or are of smooth cement. 



21. Manure must be removed from the stalls and gutters 

 at least twice daily. This must not be done during milk- 

 ing, nor within one hour prior thereto. 



22. Manure should be taken from the barn, preferably 

 drawn to the field. When the weather is such that this can 

 not be done, it should be stored not nearer than 200 feet 

 from the stable, and the manure pile should be so located

 deep, and constructed of concrete, stone, or some non- 

 absorbent material. 



25. The use of land plaster or lime is recommended upon 

 the floors and gutters, 



26. Only bedding that is clean, dry, and absorbent 

 should be used, preferably sawdust, shavings, dried leaves, 

 or straw. No horse manure should be used as bedding. 



27. The flooring where the cows stand should be so con- 

 structed that all manure will drop into the gutter and not 

 upon the floor itself. 



28. The floor should be swept daily. This must not be 

 done within one hour prior to milking-time. 



29. If individual drinking basins are used for the cows, 

 they should be frequently drained and cleaned.
