remnant of the once diverse phylum of American camels. There is 

 no good evidence, however, that the horse which survived in North 

 America till late Pleistocene times M^as ever known to the aborigines 

 until its reintroduction b;s' Europeans. Dogs they had, nevertheless, 

 universally and in some variety. Yet at this late date it is hardly 

 possible to define the various breeds or variations with any exactness 

 or to throw much light on the question of their ultimate origin. An 

 attempt is made here to gather what information the earlier travellers 

 recorded as to the appearance of the dogs of the American aborigines, 

 and so far as may be, to characterize the various breeds that can be 

 distinguished. 



A bibliography is added giving the more important papers on the 

 origin of the dog, and on prehistoric dogs of the Old World, as well as 

 jeferences to the aboriginal dogs of America.

Origin of the Domestic Dog. 



The problem of discovering the wild ancestor of the Domestic Dog 

 has engrossed the attention of naturalists from the time of Buffon to 

 the present. Basing their opinion on general external resemblances, 

 the early systematists, Giildenstadt and Pallas, favored the Indian 

 Jackal as the primitive stock whence the European dogs were derived. 

 In this course they have been followed by many later writers, but more 

 exact studies (Miller, 1912) show that the teeth of the Jackal may be
