pected weakness in this combination, that lay quiescent 

 as long as he practiced out breeding, this weakness, no 

 less than the good qualities, would l)e alarmingly appar- 

 ent in the offspring, and the herd would head straight for 

 disaster as the result of this experiment in inbreeding. 



Examples. — Suppose the same man, noting the 

 superiority of Berne's kids, whether she were bred to 

 Hermann or another buck, should decide that they owed 

 their superior qualities to Berne alone, and not in any 

 great degree to their sires. He would then breed Berne 

 to her son, Hermann II, thus strengthening by inbreed- 

 ing tlie Berne strain and its excellencies. Suppose he 

 felt it was Hermann who had made the outstanding con- 

 tribution. He would tlien breed all the does to Her- 

 mann, Berne lierself again, out breeding, his daughter 

 Berne II, inbreeding, and his two granddaughters 

 Berne III and Herma, line breeding. (It will be noted 

 tliat the i^ossibilities of inbreeding and line breeding from 

 a sire's line are far greater than from a dam's line, as the 

 dam can be bred to her descendant only the one time each 

 season, while the sire can be bred to all of his descendants 

 each season.) If the breeder was right in his first de- 

 cision, he will very slowly build up a group of animals 

 that more and more represent Berne's line and her type. 

 If he was right in the second illustration, he would very 

 rapidly estabhsh a whole herd of does that represented
