THE BEST TIME FOR APPLES

It was the first lesson after the summer holidays at a small school in England. The lesson was about the seasons of the year. "There are four seasons in the year", said the teacher. "They are Spring, Summer, Autumn and Winter. In Spring it is warm and everything begins to grow. In Summer it is hot and there are many flowers in the fields and gardens. In Autumn, there are many vegetables and much fruit. Everybody likes to eat fruit. In Winter, it is cold and it often rains. Sometimes there is snow on the ground."

Here the teacher stopped and looked at one of the pupils, "Stop talking, Tom" he said. "Now listen to me. Can you tell us when is the best time of apples?"

"Yes, sir," answered Tom. "It is when the farmer is not at home and there is no dog in the garden."
