It is very hot.The mother and het cub have been wandering about all night.Now they are sweating inside their fur. A cool stream attracts them. There are other she-bears at the stream. They have young ones, too. The cub has his first swim.The water is cry cold. At first, he struggles and sinks down,but he quickly rises to the surface.Spitting and puffing, he swims strongly with all four legs and stays afloat.
