188 THE BREEDS OF LIVE-STOCK 
summarized as follows: (1) It costs less to breed and 
raise a mule to a serviceable size than a horse. (2) Less 
time is required to prepare a lot of mules than a lot of

224. The kind of mare to breed from. — A common 
error is to suppose that as soon as a mare becomes diseased 
and unfit for horse-breeding she may be used for the 
production of mules. Perhaps this accounts for so many 
inferior mule colts. It matters not how superior the
