IN-AND-IN BREEDING. 189 



experience in breeding greyhounds, and was at one time so 

 successful as to obtain the name of " The Emperor of Coursers," 

 has laid down the rule that " once in and twice out " is the proper 

 extent to which breeding in the greyhound should be carried, and 

 probably the same will apply to other breeds. Sometimes a 

 sister may be put to a brother even, when there was no previous 

 near relationship in their sire and dam ; but though this has 

 answered well two or three times, it is not to be generally recom- 

 mended. A father may in preference be put to a daughter, 

 because there is only half the same blood in them, when the sire 

 and dam of the latter were not related ; or an uncle to a niece ; 

 but the best plan is to obtain a dog which has some considerable 

 portion of the same blood as the bitch, but separated by one or 

 two crosses ; that is to say, to put two animals together whose 

 grandfathers or great-grandfathers were brothers, but whose 

 mothers and grandmothers were no relation to each other. This 

 relationship will do equally well on the dam's side, and the grand- 

 mother may be sister to the grandsire, quite as well as having 

 the two grandsires brothers. The practice of breediug-in to 

 this extent has been extensively adopted of late years, and has 

 answered well with the greyhound, in which breed, as used 

 for public coursing, the names of " Harriet Wilson," " Hour- 

 glass," "Screw," " Sparrowhawk," " Yraye Foy," "Motley," 

 " Miss Hannah," and " Rival " speak volumes in its approbation, 

 all being in-bred and all wonderfully successful. The last-named 

 bitch is a remarkable instance, being by a half-brother out 

 of a half-sister, and yet continuing honest up to her sixth
