The Polar Hare, valued for its beautiful white fur, inhabits the countries around the Arctic Ocean, and is common in Labrador and the Hudson's Bay territory. In North America, also, there are several other species of hares: the Marsh, or Swamp Hare, of the Southern United States, which dwells among the extensive marshes of the Carolinas and Louisiana, and which freely takes to the water; the Rabbit of the Middle States, which is a true hare, though from its small size usually termed a rabbit; the Californian Hare, indigenous to California, and also another Marsh Hare, belonging to the same country. Upon the prairies several distinct species have lately been discovered, among which the Sage Hare deserves especial mention. This kind derives its name from its being a dweller on the desert plains, where scarce any other vegetation exists except the _artemisia_, or wild sage plant, the leaves of which constitute the principal food of the animal, rendering its flesh almost uneatable. The _Calling Hares_ differ very much from the common hares and rabbits-- so much as to constitute a separate genus. Their ears are shorter, and they are altogether without tails. Their habits, however, are very similar to those of the hare family, and they are therefore very naturally grouped with the latter. They derive their trivial name from the habit of uttering a note, which somewhat resembles the piping of a quail, and which can be heard at a very great distance. This note is repeated three or four times at night and morning, but is seldom heard during the middle of the day, unless when the weather is cloudy. The calling hares are distributed over Asia and North America. At least two species belong to the Himalayan country, and one is found in Cabul. In Siberia and Northern Russia there is another, called the Eadajac; and several species inhabit the northern countries of America--some so small as scarcely to exceed the dimensions of a rat! The Little Chief is one of these tiny creatures long known; but late explorers of the Rocky Mountain regions have discovered a species still smaller than the little chief.
