40 ELEMENTS OF HIPPOLOGY. 



tartar, the long vertical axis of the center teeth and their slope, 

 would confirm the error. 



A horse's teeth are said to be bishoped when a hole in the im- 

 itation of the mark is burned in his teeth. As the false mark 

 cannot be surrounded by the enamel of the genuine one, and as 

 the other tests for confirming the evidence of the mark will nec- 

 essarily fail, the deception is easy of detection. It is a trick 

 rarely resorted to. 



The tushes, or canine teeth, usually appear at about four, 

 are usually perfect at five, and show greater or less signs of 

 wear after that. 



They usually are absent in mares. This fact, and the un- 

 certainty of the time of their appearance and their rate of growth, 

 makes them almost useless as an aid to the determination of age. 

 A bright, clean tush, showing little signs of wear, is a good index 

 to a young horse; while a flat-topped, chipped, and yellow tush 

 is a usual accompaniment to age. It is not wise to place much 

 more reliance upon them.
