GRADE MEN BY THEIR LIFE GERMS 221 



that I once had a stallion go through an en- 

 tire season without fertilizing a single 

 mare. My men could not tell that there 

 was anything wrong with him by watching 

 him during the breeding season. One ex- 

 amination with the microscope told the 

 story. He had no germ cells of the proper 

 formation and was retired from the stud. 

 At another time, a great mare had been 

 barren for five years. A simple treatment 

 of boracic acid and milk of magnesia — and 

 the mare was in foal. What is true of the 

 horse is true of the human. 



This microscopic branch of science has in 

 very recent years come to the aid of the 

 practical breeder. We do not have to wait 

 until a year has elapsed to know if my 

 horses are fertile, I find out each day or 

 week, as the breeding season goes on. 



Sterility in hogs, bulls, jacks and rams 

 can thus be determined, if breeders will 

 take the trouble, by the use of the micro- 

 scope in the hands of a trained man. The 

 time will soon be at hand when breeders of 

 all animals will understand our methods 

 and the sale of a male animal for breeding
