The _fur_ of this animal, which is a native of some parts of South America, was formerly used by the Peruvians, as a fine kind of wool, and was spun and woven into stuffs of extremely delicate texture, to which they attached great value. Of late years, however, the manufacture of it has been much neglected. As a fur, the skin of the chinchilla is much in request in this country, in consequence of its having become a fashionable trimming for ladies' dresses, and a favourite article for muffs. 71. _The GREY SQUIRREL_ (Sciurus cinereus) _is a quadruped about the size of a rabbit, which has the upper parts of its body grey, and the under parts white. It is found in America, and in some countries of the north of Europe._ The _skins_ of these animals are sometimes used as a fur for the lining of winter garments, and are frequently imported into England, but they are not of much value. As, however, they are very tough, they are tanned and employed in America for many of the purposes of leather, but particularly for the making of ladies' shoes. The Laplanders, in winter, annually make war upon the troops of grey squirrels which are found in some parts of their country. This they do chiefly for the sake of their skins, which they make up into bundles of about forty each. But no merchandize is more liable to deception than this. The purchaser receives them without examination, the skins are packed with the fur inward, and all the bundles are sold at the same price. In several of the plantations of North America these animals, from their immense numbers, and the devastations they commit, are greatly injurious to the inhabitants. Rewards for their destruction are consequently given; and, in Pennsylvania alone, more than 600,000 of them have, in some years, been destroyed. The grey squirrels reside chiefly in trees, but lay up stores of provision, for winter, in holes which they dig in the ground. They are extremely agile animals, and run about among the branches with as much facility and security as upon the ground. 72. _The BLACK SQUIRREL_ (Sciurus niger) _is a small black quadruped of the squirrel tribe, which is not uncommon in North America and New Spain._ The finest furs which the Iroquois Indians possess are those of _black squirrels_. These they make into robes and garments, which they sell at a price as high as seven or eight pistoles each. 73. _The COMMON HARE_ (Lepus timidus, Fig. 26) _is distinguishable from all other animals of its tribe by the ears being tipped with black, and longer than the head; the hind-legs being half as long as the body, and the tail short._ _It is found in every quarter of the world except Africa._
