Indian Chief Predicting Cold This Winter:

It's  late fall and the Indians on a remote reservation in South  Dakota  asked their new chief if the coming winter  was going to be cold or mild.
Since he was a  chief in a modern society, he had never been taught  the old secrets. When he looked at the sky, he  couldn't tell what the  winter was going to be  like.
Nevertheless, to be on the safe side, he  told his tribe that the winte was indeed going to  be cold and that the members of the village should collect firewood to be  prepared.
But, being a practical leader, after  several days, he got an idea. He went to the phone  booth, called the National Weather Service and  asked, 'Is the coming winter going to be  cold?'
'It looks like this winter is going to be  quite cold,' the meteorologist at the weather  service responded.
So the chief went back to his  people and told them to collect even more firewood  in order to be prepared.
A week later, he called  the National Weather Service again. 'Does it still  look like it is going to be a very cold winter?'
'Yes,' the man at National Weather Service again replied,  'it's going to be a very cold winter.'
The chief again went back to his people and ordered them to  collect every scrap of firewood they could  find.
Two weeks later, the chief called the  National Weather Service again. 'Are you absolutely  sure that the winter is going to be very   cold?'
'Absolutely,' the man replied.   'It's looking more and more like it is going to be  one of the coldest winters we've ever seen.'
'How can you be so sure?' the chief asked.
The  weatherman replied, 'The Indians are collecting a boatload  of firewood'
