There are many plays in which children may amuse themselves so as to benefit both the mind and body. Exercise is very essential to the health, and all children should accustom themselves to such exercise as will give elasticity to all the muscles of the body. Some children often play too hard, and others, before they get through playing, get to quarrelling. Children never appear so badly as when they quarrel with each other. Joseph and William, Jane and little Susan, are out in the garden playing "hide and seek," around the summer house, as you see in the picture. William became a little contrary, because every thing in the play did not suit him, and declared he would run away. And you see how cross he looks at Jane, as he turns round to run away. Children should never let anger rise in their bosoms because of some small mistake on the part of others. They should always overlook all mistakes, forgive all injuries, and learn to love each other when at play, as well as when at school. Good children will play together, without getting angry, and it is a pretty sight to see such children all happy in each other's society, and enjoying their pleasant pastimes, with cheerful and happy hearts.
