So it may happen that one of the fighting herds gets so reckless that it comes into the ground of the herd that has kept neutral, and does a lot of damage there. Then what must the president of the neutral herd do? He must defend his own ground from damage. So long as the fighting herds kept to their grounds, he must not interfere. But when one of the fighting herds comes into _his_ ground and does damage, he must defend his rights. A wise elephant leader always does that; for he has bull elephants of his own who can drive out the intruders. CHAPTER III The Policemen of the Elephant Herd I have already told you that the president of an elephant herd must keep order within his own herd; that is, he must not allow a naughty elephant to commit a crime, such as to attack any other member of the herd. And if a naughty elephant does commit a crime, it is the duty of the president to punish him. I shall now tell you how he does these things. _There is a wonderful police system in an elephant herd._ You will understand that better if I tell you first about an old police system among men. You will read in history books about the Anglo-Saxons, who were the forefathers of most of the people of England and of the United States of to-day. These Anglo-Saxons had a police system like this:-- In a village or in a town all the grown-up men were divided into groups of ten men; and if any man tried to commit a crime, all the other nine men of his group tried to prevent him. If he committed the crime _before_ the other nine men could prevent him, they at least arrested him. Then they took him before the judge for punishment. It is something like that in an elephant herd in the jungle; only, as there are not so many bull elephants in a herd as there are men in a village, it is not necessary to divide the bulls into different groups. As there are only twenty or thirty grown-up bulls in an average elephant herd, it is the duty of _all_ the grown-up bulls to prevent a bad elephant among them from committing a crime; and usually it is the bulls nearest to him who actually stop him from committing the crime. If he manages to commit the crime _before_ they can prevent him, they surround him immediately and keep him there like a prisoner, till the president of the herd comes to punish him. My dear children, that is a great lesson for us. A good citizen always helps to keep the law; if he sees anyone breaking the law, he tries to prevent him from doing so. Some men do nothing, if they see a person breaking the law; they say, "It is no business of ours." Elephants are much better citizens of the jungle in that respect; they always try to prevent a bad elephant from breaking the law. [Illustration: Elephants Guarding a Bad Elephant]
