EXAMINATION FOR UNSOUNDNESS 57 



rapidly for a quarter of a mile so as to discover wind 

 troubles. The horse should be stopped quickly and then 

 by advancing close to the neck the breathing may be 

 noted whether free and easy or accompanied with a sound 

 similar to whistling. If the breathing is characterized by 

 a wheezing or whistling sound, then whistling, roaring or 

 some other disorder of the air passages is present. If the 

 origin of the sound is doubtful it might be possible to 

 result from too tight a collar have the horse taken out of 

 the harness and ridden rapidly. When the breathing is 

 not regular it is likely that the horse is troubled with the 

 heaves. In the instance of horses so afflicted, the breathing 

 is more or less spasmodic, the air from the lungs seeming 

 to be half expelled when the respiration stops for a brief 

 period and then the expulsion of the air is continued. In 

 this way the depression of the flanks is not gradual and 

 continuous as it is in the instance of the horse with sound 

 lungs but it is stayed for a short period at a time when the 

 breath is about half expelled from the lungs. 



108. Detection of Stable Vices. Horses may have many 

 stable vices that detract greatly from their utility, but 

 these cannot be discovered as a rule in the show ring. To 

 make a satisfactory examination of a horse, it is necessary 

 to see it in the stable, then have it harnessed, hitched, 

 driven and subjected to a critical examination, and after 

 these things have been given careful consideration it will 

 be only after continuous companionship on the road that 

 a man may be said to truly know his horse.
