      The journey two divers made some time ago to the deepest point on the earth makes us realize how

much of the world still remains to be studied. The two men went down seven miles to the bottom of the

Pacific Ocean inside a small steel ball to find out if there are any ocean currents (水流) or signs of life.

      It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily

found by the mother ship which would be waiting for it. The divers began preparations early in the morning

and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.

      The divers felt as if they were going down steps as they passed through warm and cold layers (层) of

water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by

telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were

quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were

frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily,

though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft

ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the

dark water and the men were surprised to see fish swimming just above them quite untroubled by the great

water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water

boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were

heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up,

arriving three hours later, cold and wet through, but none was worse for their experience.
