have an opening of 52 square inches. A 6x8 inch inlet flue 



comes nearest to providing this amount. 



The total cross-sectional area of the outlets divided by 



four (1,948 -=-4 =234), which is the number of outlets that 



will remove the foul air 

 from all parts of the 

 barn, gives a total area 

 of 234 square inches for 

 each outlet. This area 

 will be secured in a flue 

 16x16 inches. The area 

 of the outlet flues should 

 be a little greater than 

 that of the inlets. 



TAKE CARE OF THE 

 MANURE 



A dairy barn or a 

 general purpose barn, 

 must be kept clean as 

 it is a place where hu- 

 man food is produced. 

 The barn floor should be 

 so constructed as not to 

 allow water to pass 

 through it, should be free 

 from cracks and crevices, 

 and reasonably smooth 

 so that it may be cleaned 

 easily. There are two 



methods practiced in caring for manure. One system is to 

 bed stalls heavily and to clean out the manure every week. 

 The other is to clean the barn daily, hauling directly to the 

 field or storing the manure in a manure pit. The latter sys- 

 tem is, from the standpoint of cleanliness, the only satisfac- 

 tory one. 



SUPPLYING FRESH WATER 



If a water supply system is available, running water can be 

 piped directly into the barn. There are several companies 

 making satisfactory automatic water systems that require
