Fact File
Maelstr m: a powerful whirlpool in the sea or ocean.
Moskoe-strom: also known as Moskstraumen, is a system of tidal whirlpools in the Norwegian Sea, which is one of the strongest in the world. The term was first introduced into the English language by Edgar Allan Poe in 1841 through his short story “A Descent into the Maelstr m”.
Edgar Allan Poe (1809-1849) was an American writer, best known for his poetry and short stories, particularly his mystery tales.

3 What do you think will happen in the story
You are going to read a text adapted from the short story “A Descent into the Maelstr m”. Read the fact file first. Then answer the questions.
About three years ago, something terrible happened to me. That was the day when it took only six hours to break my body and soul. You think I am a very old man － but I am not. It took less than a single day to change my hair from black to white.

One day, my two brothers and I were coming back from the islands where we often risked going and got more fish than others. All at once, the sky was covered with dark clouds and in less than a minute we were in a terrible storm. A huge wave covered our boat and my younger brother fell into the sea. My elder brother put his mouth close to my ear and cried out “Moskoe-strom!” The moment I heard the word I became very frightened. I knew what he meant by that one word well enough.

With the wind and waves, we were going in the direction of the whirlpool. We were hopeless. Nothing could save us. I felt sick, as if I was falling from a mountain top in a dream. We went round and round, nearer and nearer to the horrible edge of the whirlpool. It may appear strange, but at that moment, when we were on the edge of the whirlpool, I felt calmer than when we were moving towards it. I began to think how amazing a thing it was to die in such a way, and how wonderful it was to see the power of nature. Suddenly, we went over the edge. I thought my life was over. But moment after moment passed, and I was still safe.

The boat was on the inside of the huge whirlpool and we were going round in circles at great speed. I saw clearly that there were other objects in the whirlpool — trees and barrels. After a while, I became curious about the whirlpool itself. I then made three important observations. The first, the larger the bodies were, the more rapidly they fell; the second, between two objects of equal extent, round objects fell down less rapidly; and the third, between two objects of the same size, objects shaped like a tube fell down more slowly. So I tied myself to a barrel to help me float. I tried to make my brother understand, but he was too frightened and stayed in the heavy boat. Without waiting, I jumped into the sea to try and escape.

As you can see, the reason why I’m here to tell the story is that I made the right decision. Some time after I left the boat, with my brother in it, it was pulled into the bottom of the whirlpool. Soon after that, the whirlpool became less wild. Then the sky was clear, the wind calmer, and the moon was shining. I was still tied to the barrel and the waves soon carried me to an area where the other fishermen were. In the end, a boat picked me up. I was very tired. The fishermen were my old friends, but they were unable to recognise me. When I told them my story, they did not believe it. Now I have told you, and I cannot expect you to believe me any more than the fishermen did.

The three observations were: the large objects fell into the whirlpool quicker; and the round objects and tube-shaped objects did not go into the whirlpool as quickly.
2 Why did the storyteller survive while his elder brother didn’t

4 What lessons have you learnt from the story Give your reasons.
From this story, we learn that staying calm is very important even when we are in an extremely dangerous situation. At the same time, we should observe what is happening and try to find out ways to escape from the danger.
3 What does the storyteller mean by “it took only six hours to break my body and soul”
The Moskoe-strom lasted six hours. This broke his body as the storm battered him about. It broke his soul as he lost two brothers in that time. The terror of the maelstr m has had a very negative effect on his mind and body, which he doesn’t think they will ever recover from.
