158 HEAD AND NECK, 



by causing his head to be brought into a direction which 

 might prevent him seeing clearly where he was going On 

 page 67, et seq , I have discussed at some length the subject 

 of the carriage of a horse's head and neck. 



In saddle-horses, the place where the neck comes out of 

 the chest should be marked, above, by a slight depression in 

 front of the withers , below, by another depression at the 

 point where the jugular groove meets the chest , and at each 

 side, it should be nearly flat with neck and shoulder. In 

 cart-horses, the large muscles of the shoulder stand out in 

 prominent relief from the neck, and the dip in front of the 

 withers is either absent or but faintly indicated. Owing to 

 the comparative lightness of the neck in mares and geldings, 

 the union of the neck with the head and trunk is better 

 marked in them, than in entires. 



Throat. — The wind-pipe should be large and well 

 detached from the neck ; as it will then indicate good 

 breathing power. I have noticed that roaring often 

 accompanies a wasted appearance of the tissues which 

 cover the larynx. I am of course aware that the typical 

 form of roaring is caused by paralysis of one or both of the 

 muscles which open the larynx ; and that their size is too 

 small to account for the peculiarly emaciated condition to 

 which I have alluded.
