EMBRYOLOGY, IMPREGNATION, CONCEPTION. 43 



Any man who stands stallions may measur- 

 ably increase his returns from foals by using 

 this process of impregnation. The service of a 

 much favored stallion may be greatly extended 

 by it. Some mares make a great fuss when 

 they are to be bred and others are atrociously 

 mean when in heat. All such may easily be 

 dealt with by keeping the horse out of their 

 sight and operating quietly upon them. I have 

 carried a filled capsule forty feet and suc- 

 cessfully impregnated a female burro from a 

 service performed by a Shetland Pony stallion 

 to a mare of his own kind. The little stallion 

 refused the burro altogether and she in turn 

 could not be coaxed to go near him. The cap- 

 sule and a little ingenuity overcame the difficul- 

 ty and she foaled a fine healthy hinny. 



Whenever the operation is to be performed 

 the mare should either be hoppled or her fore 

 foot should be held up by an assistant. The 

 hair of the tail should be braided or sacked 

 down the length of the dock so that it does not 

 interfere with the operation, and an assistant 

 should stand ready to pull it out of the way if 

 necessary. I have made a study of this matter 

 of impregnation and the more I see and learn 

 of it the more deeply impressed I am with the 

 great possibilities, financial and otherwise, in- 

 herent in it. I was the first to exploit the cap- 

 sule method of impregnating mares — I invented 

 that method — and have had an extended ex-
