Scientists used to explore(探测)on the surface of the ocean. Now they are exploring below the surface， too. They want to know about ocean water and the plant and animal life deep in the ocean.

In 1934 the scientist William Beebe dived 3 000 feet below the surface in a hollow steel ball. In 1935 August Piccard dived 10 330 feet. In 1960 his son Jean dived to a depth of 35 800 feet.

All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below surface. Gradually they succeeded.Cousteau，a Frenchman，was able to keep men down to a depth of 36 feet for one month and to a depth of 90 feet for a week.

Now scientists are developing even better equipment. With this new equipment，men can stay below the surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then，in 1964，he set up another station on the ocean floor of the Red Sea.This was the first undersea station to operate without help from the surface.

Many countries are now studying undersea living. The former Soviet Union has an undersea laboratory in the Crimean Sea.The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands. In 1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next came other teams of men. All were there to explore the ocean depths and to make plans for the use of its resources. Scientists hope to find enough mineral，vegetable，and animal wealth there to provide food for the entire world.

A man once said how useless it was to put advertisements in the newspapers. "Last week," said he, "my umbrella was stolen from a London church. As it was a present, I spent twice its worth in advertising, but didn't get it back."

"How did you write your advertisement?" asked one of the listeners, a merchant.

"Here it is," said the man, taking out of his pocket a slip（纸条） cut from a newspaper. The other man took it and read, "Lost from the City Church last Sunday evening, a black silk umbrella. The gentleman who finds it will receive ten shillings（先令） on leaving it at No.10 Broad Street."

　　"Now," said the merchant, "I often advertise, and find that it pays me well. But the way in which an advertisement is expressed is of extreme importance. Let us try for your umbrella again, and if it fails, I'll buy you a new one."

　　The merchant then took a slip of paper out of his pocket and wrote: "If the man who was seen to take an umbrella from the City Church last Sunday evening doesn't wish to get into trouble, he will return the umbrella to No. 10 Broad Street. He is well known."

　　This appeared in the paper, and on the following morning, the man was astonished when he opened the front door. In the doorway lay at least twelve umbrellas of all sizes and colours that had been thrown in, and his own was among the number. Many of them had notes fastened（系牢） to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter.
