APPENDIX. 241 



Tlie most reasonable theory is. that tlio ancc?torn 

 of the domesticated dog were a species that has entire- 

 ly disappeared from the wild state. 



One thing* is true, in all countries the dog is a 

 household pet. He is the chosen companion of all 

 classes of people, and Cuvier gives him the distinction 

 of being the only animal that has followed man over thu 

 whole world. 



Dogs give faithful and valuable service in return 

 for the protection they receive from their masters. 

 On sheep farms they defend the flocks, guide them 

 from the pastures to the sheepfold, and keep them 

 together if night or storm overtakes them. 



The dog is the farmer's best friend; he guards, 

 his poultry yard from nightly wanderers, protects his 

 garden and house from thieves, and drives his cattle 

 afield and brings them home. 



Innumerable are the stories which tell of life and 

 property saved by the timely warning given by the 

 house dog. 



In the cold Xortliern countries where there arc 

 no liorscs or oxen, dogs are used to draw sleds over 

 ice and snow. In other countries they are used to 

 himt wolves and other wild animals, and sometimes 

 they are trained to follow criminals. 



There is much reason for the assertion that the 

 Shepherd dog, or Collie, is, on the whole, the most 

 highly organized, as he certainly is the most useful 

 of all dos^s. '
