HOW TO BUY AND SELL. 61 



I myself have never known, nor have I ever met any 

 one who has known, this complaint to change into roar- 

 ing; yet, as many persons think it probable that it might 

 do so, and that it may be the remains of some disease, 

 the horse is considered to be UNSOUND. 



My opinion is that the noise proceeds from nervous- 

 ness, and not from any disease; and that as it does not 

 hinder the animal from performing the labor due from 

 one of his class, the horse is SOUND. 



However, as opinions differ upon this subject, the safest 

 course is to bar even grunting in a warranty for sound- 

 ness. 



WHISTLING. 



The presence of whistling is easily ascertained by a

 the wheezing or whistling noise. This malady may or

 another disease, the whistling will vanish with the dis- 

 ease: thus, for instance, it frequently accompanies a cold, 

 but, on the cold being cured, vanishes and is not heard 

 again. Where it assumes a chronic form, as it fre- 

 quently does when produced by water on the chest, by 

 inflammation of the lungs, or by injury to the windpipe, 

 it is incurable. 



As the cold is, per se, an unsoundness, whistling is, of 

 course, in this, its least aggravated form, an 



UNSOUNDNESS. 



When a good and serviceable horse has become affected 

 with whistling only in his gallop, and not in his trot, 

 he does not suffer inconvenience from this pace, and he 

 may advantageously, if suited to that kind of work, be 

 put into harness ; and although there may exist some lit- 

 tle wheezing, a fair pace does not distress the animal; he
