The rat is dangerously ferocious when aroused, and is capable of being wrought up to a pitch of white heat fury. If he should be caught, his tail cut, his hair burnt, or if he should be wounded in any other way, but not sufficiently to weaken his system or momentary capacity, and he is then let loose, he will, through sheer madness and pure "cussedness," hunt up, fight, and overpower his brethren individually, or else put them to flight in a body, without much ado. In fact, when he is worked up to this state, he wouldn't hesitate for a moment to attack an entire army of rats, or of other far bigger and more terrible objects. In many cases like this, rats have often obligingly rid premises of their own kind. If the tortured or maimed rat is in a weak condition afterwards, he will be promptly overpowered by the other members of the rat community upon general principles. We are often regaled in the newspapers with "brutally frank" accounts of people leaving their babies alone at home, and, upon returning, finding them frightfully lacerated by rats, slowly and reluctantly escaping from the scene. In like manner, they have become bold enough to attack solitary invalids in houses, who had work enough to defend themselves from, and to drive off, these ferocious little beasts, driven on by hunger like the true wolves of the wilderness. Living or dead, man is bound to furnish food for the rat; and in church-yards, where, ghoul-like, they choose the night as their time of appearing, they demolish the skeletons, littering the ground with remnants of the white, shining bones.
