This is the story about the descent of Kodavu people.

As every child needs support and guidance of his parents every now and then, Dell’s parents set a perfect example of parenting while dealing with the uncommon talent of Dell by giving him freedom to set his priorities and a bout of chance to prove himself right. Dell’s parents were very patient with his aspirations and handled it with care by giving him an opportunity to decide between college study and business.

Dell’s roommates prevented him from entering his room because the quarter he shared with them was in complete chaos. There were boxes piled high, computer boards and tools scattered all around and they were probably disturbed by the mess in the room.

Dell was an intelligent student. His parents were concerned about his grades and wanted him to complete the degree. They were worried about him when he said that he wanted to quit college to start his own company. When they came to know that he wanted to compete with a huge company like IBM, they became anxious. They thought this was not a good idea, since Dell didn’t even have a college degree. Thus his father disliked his idea of starting a business.

Narayan is shocked when he hears about the multi-storeyed hotel which is going to be built with three hundred rooms. The surprising element is the village is a small one with only five hundred inhabitants. He is worried about the houses of the people there.

It is possible to realize your dream with hard work, determination and the desire to succeed. People around might find our dreams and ambitions impractical, but we shouldn’t be disheartened. We should pursue our dreams with full determination. This is the lesson we all learn from Dell’s story.

The grandrhother says that she was born at the turn of the century when there were no motorcars, no aeroplanes, no television, no movies, and much less noise. She has lived there all her life on the slopes of Dharmagiri. The river, trees, flowers, birds and animals are all her friends.

Grandmother is very old with children, grandchildren, and great-grandchildren. She is much concerned not only about the people of the village but also the flora and fauna of the village. She is concerned about the ecological balance of the nature.

The grandmother says she was born when there were no motor cars, airplanes, televisions and movies. There was much less noise. She has lived there all her life. She says, “The rivers, trees, flowers and birds are her friends” and she can’ stand their destruction.

But the young villagers don’t mind if the new five- star hotel is built there. They think rich tourists will come and that means a lot of money coming in. They too might get some money by doing things for the tourists. Kannan says, “if someone wants to build a grand hotel, I don’t see any harm. It will bring in tourists. Tourists mean money, and who does not need money”

SAVE DHARMAGIRI, SAVE OUR LIVES

Her grandson is the local school’s headmaster. Tomorrow’s world is the world of children. Children should know about the hazards their village will have to face.

The grandmother mocks at the rich people of the new generation by this comment. She complains about their selfish and money-minded attitude.

The grandmother says that tomorrow’s world is children’s world and her grandson being the headmaster must talk to the children about the hazards the village is going to face.

When the box was opened, Mij went out of the box. He disappeared at a high speed down the aircraft. There were cries all around. A woman stood up on her seat screaming that there was a rat. He saw Mij’s tail disappearing beneath the legs of an Indian passenger. He dived for it, but missed. The airhostess suggested him to be seated and that she would find the otter. After a while, Mij had returned to him. It climbed on his knee and began to rub its nose on his face and neck.

As there was no other way to carry Mij to London so the author had put it back into the box. He must have felt pity in the way the otter had hurt itself. Moreover, he must be worried as well.

Maxwell said that the airhostess was “the very queen of her kind” because she was extremely friendly and helpful. He took her into his confidence about the incident with the box. She suggested that he might prefer to have his pet on his knee. Hearing this, he developed a profound admiration for her, for she understood the pain of both the otter and its owner.

Valli’s favourite pastime was standing in the front doorway of her house and watching what was happening in the street outside.

Mij had invented a game with ping- pong ball. He would put the ball at one end of a sloping lid and then grab it as it ran to the other end.

Otters belong to a comparatively small group of animals called Mustellines, shared by the badger, mongoose, weasel, stoat, mink and others. Maxwell’s otter was of a race previously unknown to science and was at length named by zoologists Lutrogale perspicillata maxwelli or Maxwell’s otter. They are found in large numbers in marshes.

They are often tamed by the Arabs. It is characteristic of otters that every drop of water must be extended and spread about the place; a bowl must at once be overturned, or, if it would not be overturned, be sat in and splashed in until’ it overflowed. For them, water must be kept on the move. Otters love playing various games, especially with a ball.

Gandhiji wanted Vijaya Lakshmi Pandit to cleanse her heart of anger and pride and make peace with her husband’s family before going abroad. However, Mrs. Pandit said that she did not want to do that even to please Gandhiji.

Compulsive habits are usually strange acts or behaviour which a person does without clear reason.

On their way to and from school, children make it a habit to place their feet exactly on the center of each paving block. Similarly, Mij had made it a habit to jump on to the school wall and go galloping all along its length of thirty yards.

According to Maxwell, the average Londoner does not recognize an otter. The Londoners who saw Mij made different guesses about who Mij was. They guessed, among other things, that it was a baby seal, a squirrel, a walrus, a hippo, a beaver, a bear cub, a leopard and a brontosaur.

Otters belong to a comparatively small group of. animals called Mustellines, shared by the badger, mongoose, weasel, stoat, mink and others.

Maxwell got his mail after 5 days due to some delay. He cabled and tried to telephone in order to get his mail.

Mij was an intelligent animal. It invented its own game out of the ping-pong balls. It screwed the tap till water began to flow and then it would play and splash in the water. Though it was aloof and indifferent in the beginning, it soon became very friendly. It formed a special attachment with Maxwell. It responded when Maxwell called out his name.

It grew desperate when Maxwell left it in a box and it got hurt while trying to come out of it. After Maxwell took it out, it clung to his feet. It was a fun-loving animal. It enjoyed playing all kinds of games. It would play with a selection of toys, ping-pong balls, marbles, rubber fruit and a terrapin shell. It required love and affection from Maxwell and it got that readily.

The British airline to London would not fly animals. So, Maxwell booked a flight to Paris on another airline and from there to London. The airline insisted that Mij should be packed into a box not more than eighteen inches square. Thus, Mij was transported to England in that box, which was kept on the floor at the writer’s feet.

Mij used to follow the narrator while walking on the streets. He developed certain habits during those walks. He went with him like children playing, running and touching things in the street. He would take the author near the wall of a primary school and then gallop on it.

In today’s world, it is getting difficult to find people who show their care and support. Rather than helping others, they start giving excuses and quote rules and regulations. Earlier, people used to think about the situation faced by others and helped them in all possible ways. This is changing because of the change in the values of the people. People give first priority to their own safety and security. They care for themselves first and then think about others.

While staying in London, Mijbil would play for hours with his own selection of toys. His favourite toys were ping-pong balls, marbles, rubber fruit and a terrapin shell that the narrator had bought from his native marshes.

Mij spent most of his time in play. He spent hours shuffling the rubber ball round the room like a four-footed soccer player. His real play was when he used to juggle small objects between his paws. Marbles were his favourite toy for his pastime.

The first thing that the narrator observed about the otter was that he liked to play with water. When he was taken to the bathroom, for half an hour he went wild in the water with joy. He was plunging, jumping and ’ rolling in the water.

The narrator was not able to contact because the telephone lines had to be booked twenty-four hours in advance. On the first day, the line was out of order; on the second day, the exchange was closed for a religious holiday; and on the third day, there was a breakdown.

We’can see that Vijaya Lakshmi Pandit was a woman of substance. After losing her husband, when she was made to understand that she was not entitled to her husband’s property, she resented the idea that her identity was established only through her husband. She was displeased that though she had fought, just as men had, for the freedom of India, according to the age-old ideas of conventional people, she had no individual existence.

But she was a woman of strength and calibre. That is why she had the privilege of heading the Indian delegation to the United Nations. We can see from the excerpt that she was a good hostess too. She had the ability to manage a difficult situation and turn it into a pleasant one.
