     Canada Geese are large blue and white birds. When autumn comes. they have to move to south where

the weather is warmer. The winters are so cold in Canada that the birds will die if they stay there.

     Last spring, Bill and a man found sixteen young Canada Geese on his farm. They had lost their way. Bill

thought, "These young birds won't know what to do in the autumn." He had a small plane and he decided to

teach the birds to follow him. All through the summer, he went on short trips in his plane and the young geese

new after him.

     When the cold weather arrived in the autumn,Bill flew to Virginia in the United States. 600 miles South of

his home in Canada. The geese followed him all the way. Bill left the geese in Virginia and he returned home.

     This spring,Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia to get

them. He looked for them for two weeks but he couldn't find them. When he arrived back home, he found the

geese waiting for him. They had found their way home without him!
