"^"^ THE NEW EVOLUTION '^^"^^ 



It is not necessary here to describe the diverse 

 bodily forms characteristic of these well known breeds 

 of dogs. But their mental traits call for brief 

 consideration. Viewed in relation to the structure 

 of these dogs, they are extremely interesting. 



The greyhounds, or as they are sometimes called 

 the "gaze hounds," have deficient powers of scent, 

 but unusually keen eyes and ears. They hunt entirely 

 by sight. The hounds have poor sight, and hunt 

 almost exclusively by scent. Bull-dogs are deficient 

 both in sight and scent and are stupid and ferocious, 

 displaying little affection. Pugs, which are much 

 like bull-dogs and are equally stupid, differ markedly 

 from them in being both timid and affectionate. 



Now although the early history of the domestic 

 dogs is involved in complete obscurity since the com- 

 panionship of dogs and man runs back into the Stone 

 Age, far beyond the first beginnings of history, it 

 seems to be quite clear that certain types of dogs, at 

 least, appeared as wide and abrupt departures from 

 parents of a very different bodily form and with 

 widely different mental traits. 



We seem to be quite within the facts in stating that 

 the bull-dogs, the pugs, and the strange hairless dogs 

 appeared suddenly as anomalous types which, appeal- 

 ing to human fancy, have been perpetuated and their 

 peculiarities accentuated, or at least preserved, by 

 careful breeding. 



The greyhounds existed in the typical form in the 

 early days of ancient Egypt, and the modern hounds 

 go back to the later days of the Roman empire, so
