In the cold North there is always snow on the ground. Even in summer it is very cold there. Here is the home of the polar bear. He does not mind the cold. He has a coat of thick white fur.

　　The polar bear likes the cold air as much as you like the warm sunlight. He does not fall on the ice because he has long hair on his paws and he walks very softly. He is very good swimmer and can swim a hundred miles form the shore. In the sea the polar bear catches seals for his dinner.

　　He often walks over the ice and looks for a place where there is no ice.

　　He knows that a seal likes to put out its head, so he sits down and watches. When the round head of the seal comes up, the bear jumps at it. He pulls the seal out of the water, kills it and eats it.　　 Sometimes the bear jumps into the water himself and catches a fish.

　　In summer the polar bear also looks for berries. When he is very hungry he eats even the seaweed on the shore.

　　The people who live in the far North hum the polar bear. His meat and fat give them food, his thick skin gives them a warm bed.

　　They also cut it up and make it into coats, hats and gloves.
