　　When we think of money, we think of coins and paper bills. That is what money is today. But in the past people used many things instead of money. Some countries used cows. Other countries used salt, tobacco(烟草), or stones. Today there are still some places in the world that do not use paper money. One place is the island of Yap in the Pacific Ocean.

　　On the island of Yap, people use the heaviest money in the world－Yap stones. These are round, white stones with a hole in the middle. The Yap stones do not originate(起源) from the island. The Yap men have to go to islands four hundred miles away to get them. Big stones can be twelve feet high－as big as two tall men. Small stones are as big as a dinner plate.

　　Rich people do not carry the Yap stones. Servants(仆人) Follow the rich. Each servant carries a stone on a long stick over his shoulder(肩膀). Today the people on the island use paper money for everyday shopping. But for other things they still prefer Yap stones.

Do you think stones can move by themselves? There are some famous moving stones in Death Valley, the US. Many of the stones are small but a few of them are very big. Some of the big stones are as big as a man. The biggest stone weighs about 350kg.

The stones only move at night. Nobody has ever seen them moving, but now scientists know the answer to the question. The answer is the wind. When the wind comes from the west, the stones move to the east. When the wind is from the north, they always move to the south. But how can the wind move a very heavy stone?

Death Valley is one of the hottest places in the world, but it can be very cold at night. Sometimes, there are even bad storms （风暴） at night. Rain falls, and the wind is strong and cold. The water on the ground turns into ice easily. Then the strong wind can move the stones along the flat （平坦的）ground. In the morning, the sun comes up and dries the ground. So people can find them move from one place to another in the daytime.
