showing the strong tendency of this disease to be in- 

 herited. Never breed from a sire or dam that has a 

 curb. 



DIARRHEA. There is a form of diarrhea which is 

 sometimes present in trotters, that seems to be caused 

 by a constitutional irritation of the bowels. In many 

 cases the subjects of this affection cannot be driven in

 An animal that is subject to this disease should not 

 be bred from.

 made to run to the top of their speed, are affected with 

 this serious condition of bleeding from the nostrils. 

 This is also due to inherited and constitutional causes, 

 and if this condition is present in any proposed candi- 

 date for the stud, he or she should be rigidly excluded 

 from the breeding establishment. 



FEET IMPERFECTIONS OF. The shape and 

 form of the feet tend very strongly to be inherited, and 

 any weakness which may be present in the sire or dam 

 will be very likely to appear in the offspring. One of 

 the worst faults in respect to the feet is seen when they 

 are small and cramped, and when the horn is thin and 

 has a tendency to become dry and brittle. This form

 and are the easy subjects of- bruises to the soles, by 

 stepping on stones and other solid objects projecting
