Til£ STABLE. 257 



convinciiig proof of the noxious and stimulating 

 nature of such an atmosphere ; yet such is tlie 

 obstinacy and ignorance of gfoonis in general, 

 ihat they cannot be previiiied upon to abandon 

 this injurious practice. Even at this time 

 stables are generally built too low, and un- 

 provided with eifectual means of ventiJatioiv 

 A stable should be as lofty as it can be made 

 conveniently, at least twelve feet; the foul air 

 will then circulate in the higher parts, and the 

 animal will not be constantly breathhig an un^ 

 wholesome atmosphere, which he must do 

 when the ceiling is scarcely higher than his 

 head. Proper apertures must be also made 

 in the ceiling, communicating with the at- 

 mosphere by square wooden tubes, so con« 

 trived as not to admit the rain into the stable : 

 the foul air and other unwholesome vapours 

 will then readily pass off, while a proper 

 quantity of fresh air may bf admitted by means 

 of windows. The next circumstance to be 

 attended to is nearly connected with, and not 

 less important than, ventilation; namely, the 

 so constructing a stable as to be able to 

 regulate its temperature, or keep the air at any 

 degree of heat that may be thought proper.
