THE MELTING-POT'' : " iof 



by another breed. Such short-legged cattle are 

 distinguished from ordinary Kerries by being 

 called " Dexters." 



Still another case might be quoted. At one 

 time the cattle of Suffolk were hornless and 

 light dun, while their neighbours were horned 

 and red. Breeders preferred the hornlessness 

 of the one breed and the redness of the other. 

 The hornless character is dominant to the 

 horned ; consequently, as a result of crossing 

 horned and hornless cattle, there were produced 

 pure hornless cattle, masquerading hornless 

 cattle, and horned cattle ; but, by continually 

 selecting hornless ones to breed from, the 

 masqueraders and the horned ones were worked 

 out. When the light dun Suffolks were crossed 

 by red cattle, there resulted yellow intermediate 

 hybrids ; but when these were crossed by red 

 cattle, half their progeny were red. By the 

 persistent selection of red-coloured cattle, the 

 original light dun colour and its derivative yellow 

 were eventually worked out. Thus the old 

 Suffolks and their neighbours became one breed : 

 the Suffolks giving up their colour and their 

 neighbours their horns. 



It is not necessary for us to consider cases in 

 which three or more characters have been trans- 

 ferred from one breed to another.
