GENERAL PRINCIPLES OF BREEDING. 87 



Mary Lewis began with two male foals, the 

 second being by Glencoe; her next foal, also by 

 Glencoe, was a filly, and all her foals after that 

 (six more), by four other sires, were females. 

 Olivia produced seven males in succession from 

 four different sires before she dropped her first 

 filly. Neither Jack Malone, Muggins, John Mor- 

 gan nor Bonnie Scotland could get anything 

 but fillies out of Lantana. Mollie Hambleton 

 produced six fillies in succession, three of them 

 by Planet, and then she faced about and threw 

 two male foals to Planet. In short, the pages 

 of the stud and herd books furnish a complete 

 refutation to any rule that has yet been formu- 

 lated upon this subject. 



It may be that we shall ultimately discover 

 the circumstances under which these various 

 causes operate upon each other, so that we shall 

 be able, in many cases, to produce a given sex 

 at will, but at present we know but little if any 

 more upon the subject than was known by our 

 grandfathers.
