Nature has given every life senses to carry life on. Many of such senses have puzzled us until today.
What guides bee when it flies home? How do carrier pigeons find their way home over hundreds of miles? How do blind ants know wher their is? How do cats know to eat some kinds of grass when they are ill? And so on.
When young bees fly from the hive for the time, they make only short fights. These flights are not to test their wings but to get to know the country. The bees fly a yard or two, circle round, and then fly on. Each flight is longer than the one before. At last they know all the landmark around the hive. They find their way home becsuse they have flown ovet the country and have seen it. In fact, they know its geography.
