VENTILATION 59 



per head, an utterly impossible amount to give when the 

 expense of stable construction is considered, but still the 

 theoretical amount where expense is no objection, and only 

 a small number of changes of air per hour are desired. 



The cubic space fixed for army horses in the type of 

 stable built during the last 30 years is 1,605 feet per head. 

 This appears to agree with the cubic space allowed by some 

 large companies and intelligent horse proprietors. 



If 1,600 cubic feet be taken as representing the space 

 allowed to horses living under the best possible conditions, 

 the supply of 15,000 cubic feet of air can only be effected 

 by the air of the stable being changed nine and a half 

 times per hour. 



Will a horse stand the air of the stable being changed 

 nine times an hour in winter without suffering from 

 draught ? 



There can be no doubt that, if properly fed, the natural 

 coat not removed, or if removed a blanket given to take 

 its place, horses will stand these changes with impunity. 

 It practically means living in the open, for the air of the 

 stable is changed about once every six minutes, but without 

 the disadvantages of rain, snow, and wet ground to contend 

 against, which living in the open entails. 



Horses living under these conditions will not carry a fine 

 glossy coat, but will be better able to withstand exposure to 

 weather, such as working animals are at all times called 

 upon to face, both in civil and military life. 



Hot stables produce a fine glossy coat, economise the 

 food so that the animals put on fat, but they also render 

 them more susceptible to disease. Cold stables produce a 

 heavy coat, there is not much tendency to the accumulation 

 of fat, and the animals require more to eat owing to the call 

 on the heat producing function. In return they are healthy, 

 and the chance of chill from exposure is very small. 



In the case of cattle it may be urged the amount of fresh 

 air required would keep the temperature too low both for 

 fattening and milk production. It is quite true the stormg 

 up of fat, and the constant drain on the mammary gland
