JACKS, JENNKTS AND MUI.KS 29 



gard it of more importance than height, yet the height 

 has its bearing in the selling of a jack as well as a 

 mule. Mules are generally classified by their height, 

 and more importance is attached to it than I think 

 should be. A jennet jack ought to have a long, thin, 

 bony head, with long, well-tapered ears, sitting grace- 

 fully on his head; large, flat, clean limbs, big foot, 

 deeply cupped. As to color, it should be a good black 

 with distinct white points. The pelvis, or breadth of 

 hips, is very essential, either in jack or jennet. I have 

 known jennets so deficient or narrow in the pelvis that 

 they had great difficulty in giving birth to their off- 

 spring.
