SPECULATIONS 143 



low grade milkers were masqueraders, then 

 apparently there would only be two grades of 

 cows ; but two-thirds or so of one of the grades 

 would be masqueraders. The difficulty again 

 would be to find a bull that was pure high grade. 

 Again there is only one test, the breeding test ; 

 and in this case it might be summed up shortly 

 by saying that if a bull is pure high grade, his 

 daughters from both kinds of cows ought all to be 

 high grade milkers. 



One other character might be suggested, as an 

 example. It has been found that the short legs 

 of animals of North Devon type are dominant to 

 the long legs of the Kerry. The same seems to 

 be the case among Shorthorns and Aberdeen- 

 Angus. That is, short-legged Shorthorns and 

 Aberdeen-Angus are dominant to long-legged 

 ones. That being so, there occurs in these breeds 

 occasionally a long-legged animal, just as a red 

 animal sometimes appears among Aberdeen- 

 Angus. Bred to a short-legged beast, this 

 animal's progeny will be short-legged, but not 

 pure. It will be a masquerader. If it be a bull 

 and put to short-legged cows, the progeny will 

 also be short-legged, but half their number will 

 be impure. If that bull be followed by another 

 of similar character, a quarter of his progeny 

 from the previous bull's daughters will be long- 

 legged. 



These are only two characters that might be
