There are some extraordinary accounts of the dexterity, as well as courage, of the terrier in destroying rats. The feats of a dog called "Billy" will he long remembered. He was matched to destroy one hundred large rats in eight and a half minutes. The rats were brought into the ring in bags, and, as soon as the number was complete, he was put over the railing. In six minutes and thirty-five seconds they were all destroyed. In another match he destroyed the same number in six minutes and thirteen seconds. At length, when he was getting old, and had but two teeth and one eye left, a wager was laid of thirty sovereigns, by the owner of a Berkshire bitch, that she would kill fifty rats in less time than Billy. The old dog killed his fifty in five minutes and six seconds. The pit was then cleared, and the bitch let in. When she had killed thirty rats, she was completely exhausted, fell into a fit, and lay barking and yelping, utterly incapable of completing her task. The speed of the terrier is very great. One has been known to run six miles in thirty-two minutes. He needs to be a fleet dog if, with his comparatively little bulk, he can keep up with the foxhound. A small breed of 'wry-legged' terriers was once in repute, and, to a certain degree, is retained for the purpose of hunting rabbits. It probably originated in some rickety specimens, remarkable for the slow development of their frame, except in the head, the belly, and the joints, which enlarge at the expense of the other parts. THE SCOTCH TERRIER There is reason to believe that this dog is far older than the English terrier. There are three varieties: first the common Scotch terrier, twelve or thirteen inches high; his body muscular and compact-- considerable breadth across the loins--the legs shorter and stouter than those of the English terriers. The head large in proportion to the size of the body--the muzzle small and pointed--strong marks of intelligence in the countenance--warm attachment to his master, and the evident devotion of every power to the fulfilment of his wishes. The hair is long and tough, and extending over the whole of the frame. In colour, they are black or fawn: the white, yellow, or pied are always deficient in purity of blood. Another species has nearly the same conformation, but is covered with longer, more curly, and stouter hair; the legs being apparently, but not actually, shorter. This kind of dog prevails in the greater part of the Western Islands of Scotland, and some of them, where the hair has obtained its full development, are much admired.
