So if the herd has chosen merely the biggest and strongest elephant to be their president and he makes such mistakes as that, they soon depose him; that is, they no longer follow him. They look around for some other leader who can discover a better way, and they follow him instead. And if afterward they find that he is wise and clever, and does not make mistakes, they follow him as their leader every day after that, even if he is not quite so big and strong as the other elephant was. He then becomes the new president, if he is at least strong enough to make a good gap through the jungle. Most of the elephants could pass through that; only the biggest bull, the deposed president, would have the trouble of enlarging the gap with his body in going through it. And this would serve him right! In the same manner the leader of the herd must not go over ground that is _too hard_, for elephants are such heavy animals that it jars the bones of their feet to go over hard ground for a great distance. If there has been no rain for several weeks, then in a hot country the ground gets very hard in some places. So if there has been no rain near a herd for some time, a wise leader avoids these hard places. So, as you see, an elephant leader has to be quite clever in merely avoiding difficulties, in the daily search for food. And that is not all! The food itself may be plentiful in one part of the jungle, and rather scarce in another; for in one direction there may have been just enough showers recently to bring out the fresh leaves on the trees; but in another direction there may have been no rain at all for some time, and so there would be no fresh leaves there. Why, even in your own town there may be a good shower of rain in one part of the town, and no rain at all in another part. So it might be in the jungle; a wise leader would know this by instinct, and he would take the herd along that part of the jungle where there had been recent showers of rain, and where there would be enough fresh leaves. _He Must Provide Daily Drink_ After the elephants have had enough to eat for the day, they must have enough clear water to drink. And to get this is _the hardest daily duty of the leader_. In the jungle, even if the leader makes a little mistake and goes the wrong way, there may still be enough to eat, because the elephants can always find enough trees in the end by going a little farther: so they would have only a little more trouble in getting their food, if the leader made a mistake. But with _water_ it is quite different--the leader may find no water at all, if he makes a mistake and leads the herd the wrong way. "Then how must he lead the herd so as to find water, as well as food?" you may ask.
