Then we have a class of Dogs distinct from these friends and servants of mankind. These live either entirely wild or half-wild, and are scattered over various parts of the globe. These are the Dingo, or New Holland Dog, which is very destructive to domestic animals, and even to cattle; the Dhale, or East Indian Dog, which in packs, pursues Deer, Gazelles, etc., and which, when collected in troops, does not fear to fight with the Lion or Tiger; the Wild Dog of Sumatra; the Cape of Good Hope Dog and the Maroon Dog of America. THE HYENA DOG. [Illustration: HYENA DOGS.] The Hyena Dog might be classed with these wild and half-wild Dogs, although it is usually given a distinct genus. As the name indicates, it has several points of resemblance with the Hyena. This Dog inhabits South Africa. It is about the size of a Wolf, but not so strong as that animal. Its coat is of a deep gray color speckled with spots of various colors. It has large pointed ears and the tail is long and bushy. Although like the Hyena, it is very fond of putrid flesh, the Hyena Dog also feeds on living prey, especially Gazelles, Antelopes, etc. To pursue and capture these, the Hyena Dogs collect in troops, which are sometimes very numerous, and under the direction of a chief, they hunt with an intelligence unsurpassed by the best pack of Hounds. When the game is taken they divide it equally, but if any of the larger Carnivorous animals approach to take a share in the feast, they all unite against the intruder. Even Leopards and Lions have been driven off by a troop of these fierce Hyena Dogs. THE DESTRUCTIVE WOLF. [Illustration: WOLF.] Wherever the Wolf is found it is especially dreaded by the owners of flocks and herds, and it is considered the most destructive quadruped met with in Europe. Both in their habits and their physical structure they are very closely related to the Dog. The sense of smell in the Wolf is very acute, but its speed is not great. It wearies out its victim by untiring perseverance and when in full chase it persistently follows the track of the fugitive. The Wolf is found throughout the whole of Europe, excepting Great Britain and the neighboring islands, where it has been exterminated. It also inhabits the cold and temperate regions of Asia and America. In some natural excavation situated in the woods, the Wolf takes up its abode. From here it steals forth at night to prey upon all the weaker animal life. Among the varieties of the Common Wolf, it is necessary to mention the Black Wolf, which inhabits the North of Europe, and the Black Wolves of the Himalayas; the Dusky Wolf and the Prairie Wolf, which lives in troops on the great plains of North America; the Red Wolf, which leads a solitary life on the pampas of La Plata and in Texas and Mexico; lastly, the Mexican Wolf or Coyotte, and the Java Wolf. In the glacial regions of the two continents, White Wolves are found.
