When the Old and New Cities of Jerusalem were reunited in 1967， a recently widowed Arab woman， who had been living in Old Jerusalem since 1948， wanted to see once more the house in which she formerly lived. Now that the city was one， she searched for and found her old home. She knocked on the door of the apartme，nt， and a Jewish widow came to the door and greeted her. The Arab woman explained that she had lived there until 1948 and wanted to look around. She was invited in and offered coffee. The Arab woman said， "When I lived here， I hid some valuables. If they are still here， I will share them with you half and half. " The Jewish woman refused. "If they belonged to you and are still here， they are yours. " After much discussion back and forth， they entered the bathroom， loosened the floor planks， and found a hoard of gold coins. The Jewish woman said， "I shall ask the government to let you keep them. " She did and permission was granted.
The two widows visited each other again and again， and one day the Arab woman told her， "You know， in the 1948 fighting here， my husband and I were so frightened that we ran away to escape. We grabbed our belongings， took the children， and each fled separately. We had a three-month-old son. I thought my husband had taken him， and he thought I had. Imagine our grief when we were reunited in Old Jerusalem to find that neither of us had taken the child. "
The Jewish woman turned pale， and asked the exact date. The Arab woman named the date and the hour， and the Jewish widow told her: "My husband was one of the Israeli troops that entered Jerusalem. He came into this house and found a baby on the floor. He asked if he could keep the house and the baby， too. Permission was granted. "
At that moment， a twenty-year-old Israeli soldier in uniform. walked into the room， and the Jewish woman broke down in tears. "This is your son， " she cried. This is one of those incredible tales we hear. And the aftermath？ The two women liked each other so much that the Jewish widow asked the Arab mother: "Look， we are both widows living alone. Our children are grown up. This house has brought you luck. You have found your son， or our son. Why don"t we live together？" And they do.

How can we get rid of garbage？ Do we have enough energy sources to meet our future energy needs？
These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source， and at the time it can save the land to hold garbage.
For a long time， people buried garbage or dumped it on empty land. Now， empty land is scarce.
But more and more garbage is produced each year. However， garbage can be a good fuel to use. The things in garbage do not look like coal， petroleum， or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies， we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to bol water. The
steam that is produced is used to make electricity or to heat nearby buildings. In Paris， France， some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.
Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs.
