in fact, detect no marked difference between them; and Messrs. Nott and
Gliddon give additional details showing their close resemblance. The dogs
derived from the above two aboriginal sources cross together and with the
wild wolves, at least with the C. occidentalis, and with European dogs. In
Florida, according to Bartram, the black wolf-dog of the Indians differs in
nothing from the wolves of that country except in barking. (1/15. 'Fauna
Boreali-Americana' 1829 pages 73, 78, 80. Nott and Gliddon, 'Types of
Mankind' page 383. The naturalist and traveller Bartram is quoted by
Hamilton Smith in 'Naturalist Lib.' volume 10 page 156. A Mexican domestic
dog seems also to resemble a wild dog of the same country; but this may be
the prairie-wolf. Another capable judge, Mr. J.K. Lord ('The Naturalist in
Vancouver Island' 1866 volume 2 page 218), says that the Indian dog of the
Spokans, near the Rocky Mountains, "is beyond all question nothing more
than a tamed Cayote or prairie-wolf," or Canis latrans.)

Turning to the southern parts of the new world, Columbus found two kinds of
dogs in the West Indies; and Fernandez (1/16. I quote this from Mr. R.
Hill's excellent account of the Alco or domestic dog of Mexico, in Gosse's
'Naturalist's Sojourn in Jamaica' 1851 page 329.) describes three in
Mexico: some of these native dogs were dumb--that is, did not bark. In
Guiana it has been known since the time of Buffon that the natives cross
their dogs with an aboriginal species, apparently the Canis cancrivorus.
Sir R. Schomburgk, who has so carefully explored these regions, writes to
me, "I have been repeatedly told by the Arawaak Indians, who reside near
the coast, that they cross their dogs with a wild species to improve the
breed, and individual dogs have been shown to me which certainly resembled
the C. cancrivorus much more than the common breed. It is but seldom that
the Indians keep the C. cancrivorus for domestic purposes, nor is the Ai,
another species of wild dog, and which I consider to be identical with the
Dusicyon silvestris of H. Smith, now much used by the Arecunas for the
