Although our hunting and shepherd's dogs have a European and the mastiffs an Asiatic ancestry, the ancestry of the harriers is African, and especially Egyptian; in fact, in Upper Egypt we find a sort of large white jackal (_Simenia simensis_) with the form of a harrier, and which Paul Gervais regarded with some reason as the progenitor of the domestic harrier, and a comparison of their skulls lends support to this opinion. A study of the most ancient monuments of the Pharaohs shows that the ancient Egyptians already had at least five breeds of dogs: two very slim watch dogs, much resembling the harrier, a genuine harrier, a species of brach hound and a sort of terrier with short and straight legs. All these dogs had erect ears, except the brach, in which these organs were pendent, and this proves that the animal had already undergone the effects of domestication to a greater degree than the others. The harrier of the time of the Pharaohs still exists in great numbers in Kordofan, according to Brehm. Upon the whole, we here have, then, at least three stocks of very distinct dogs: 1, a hunting or shepherd's dog, of European origin; 2, a mastiff, typical of the large breed of dogs indigenous to Asia; and 3, a harrier, indigenous to Africa. We shall not follow the effects of the combination of these three types through the ages, and the formation of the different breeds; for that we shall refer our readers to a complete work upon which we have been laboring for some years, and two parts of which have already appeared.[1] [Footnote 1: Les Races des Chiens, in La Bibliotheque de l'Eleveur.] We shall rapidly pass in review the different breeds of dogs that one may chance to meet with in our dog shows, beginning with the largest. It is again in mountainous countries that the largest dogs are raised, and the character common to all of these is a very thick coat. The largest of all, according to travelers, is the Thibetan dog. Buffon tells of having seen one which, when seated, was five feet in height. One brought back by the Prince of Wales from his voyage to the Indies was taller in stature, stronger and more stocky than a large mastiff, from which it differed, moreover, in its long and somewhat coarse hair, which was black on the back and russet beneath, the thighs and the tail being clothed with very long and silky hair. In France, we have a beautiful mountain dog--the dog of the Pyrenees--which is from 32 to 34 inches in height at the shoulders, and has a very thick white coat, spotted above with pale yellow or grayish fox color. It is very powerful, and is capable of successfully defending property or flocks against bears and wolves.
