STAI/LIONS, BROOD MAKES AND FOALS. 125 



1,930 mares served an average of 69 per. cent 

 of foals to mares served. His average of mares 

 served from the time he was three years old up 

 to the year of his death (not including 1868, 

 when he did nothing) was about 83 per year. 

 The statistics of horse-breeding in Saxony, 

 from 1856 to 1862, inclusive (seven years), also 

 confirm the position advanced on the preced- 

 ing page, viz., that the procreative power of 

 the stallion depends mainly upon his strength 

 and vigor. The returns for 1856 show that the 

 stallions that served 90 to 100 mares each pro- 

 duced a greater percentage of live foals than 

 those that served any other number, except 

 those that served from 30 to 40. In 1857 those 

 that served over 110 mares each produced 25 

 per cent more foals than those that served a 

 less number. In 1858 those that served 60 to 

 70 mares got a larger percentage of foals than 

 any other, except one that served less than 10. 

 In 1859 the highest percentage belonged to 

 those that served 50 to 60 mares. In 1860 the 

 highest belonged to those that served over 90 

 mares; while those bred to 10 or less stood 

 lowest. In 1861 those that served 80 to 90 

 mares lead, while those below 20 show the 

 smallest percentage of foals. In 1862 60 to 70 

 were the most productive, while those below 10 

 were the lowest in the percentage of foals pro- 

 duced. From this data, as well as those de-
