Air Space Required 281 



feet of air space. This is manifestly too little, 

 as 1 cubic foot of air space should be allowed 

 for each pound of live animal. Many stables, 

 in fact most stables, provide but one -half of a 

 cubic foot of air space for each pound of live 

 animal kept in them ; in such case it is im- 

 possible to keep the air approximately pure or 

 the stable decently sweet. To realize what this 

 means, suppose a bedchamber be constructed 

 for a man weighing 160 pounds. If one foot 

 of air space be provided for each pound of 

 live weight, the chamber might be built 4 feet 

 wide, 7 feet long and 6 feet high. This would 

 give 168 cubic feet of air space. If the bed- 

 chamber be made proportionally as large as 

 are most cow stables, its dimensions would be 

 3 feet wide, 6% feet long and 4% feet high. 

 To insure good air in such a sleeping room 

 one side of it would have to be knocked out. 

 If one or two box -stalls and one feed -bin are 

 provided in an 80x32 -foot barn, with 12 -foot 

 ceilings (Fig. 105), and room for a hallway, 

 3 feet wide, be left at one end of the building, 

 it will then accommodate thirty- nine animals. 

 Each one would have 800 cubic feet of air 

 space, the required amount. The first story of 

 most cow stables is about seven feet. It is 

 seen how easily the stable may be overcrowded.
