Travel and Adventure
Why This Matters
Have you ever stood near a railway track and felt the ground shake as a train rushed past? That mix of fear and excitement is hard to forget.
Some people love that feeling so much that they go looking for it. They climb mountains. They walk into dark tunnels. They ride trains to places they have never seen. We call this love of new and exciting experiences adventure.
But adventure is not only about big thrills. It is also about courage — doing the hard thing even when you are a little afraid. It is about a curious boy who wants to know what the inside of a tunnel feels like. It is about a lonely watchman who walks into the dark to save a leopard’s life. It is about a young woman who lost a leg and still decided to climb the tallest mountain on Earth.
In this unit you will meet all three. Their stories will make your heart beat a little faster. And they will quietly teach you something for life: the world is wide, the most exciting moments come to the curious and the brave, and you should never give up on a dream just because it looks impossible.
The Big Idea
Travel and adventure are not just about fun and faraway places. They are about curiosity — wanting to see and know new things — and courage — being brave enough to step into the unknown. A boy walks into a dark tunnel to learn what it is like. A watchman faces a leopard to keep others safe. A poet longs to ride any train, anywhere. A young woman climbs the world’s highest peaks on one real leg and one artificial one. This unit shows that the richest experiences in life belong to those who stay curious and refuse to give up.

This unit has three pieces. Let us take them one at a time.
- “The Tunnel” — a short story by Ruskin Bond.
- “Travel” — a poem by Edna St. Vincent Millay.
- “Conquering the Summit” — a true account about the mountaineer Arunima Sinha.
Piece 1: The Story — “The Tunnel”
This story was written by Ruskin Bond, one of India’s best-loved writers. He often writes about the hills, the jungle, and small everyday moments that turn out to be special. Let us walk through “The Tunnel” slowly.
What happens
It is almost noon. The jungle is hot and silent. A boy named Suraj stands near a railway tunnel cut into a hillside. He is not waiting for a station or a ticket. He simply loves trains. He has cycled out of town, left his cycle in a village, and walked over a hill just to watch the midday train roar out of the tunnel.
Soon he hears a whistle far away. Then a sound like thunder. Then the steam engine bursts out of the tunnel, “snorting and puffing.” To Suraj it looks like a green, black and gold dragon from his dreams. Hot steam hits his face. In a moment the train is gone, leaving only a thin line of smoke.
Now the jungle is quiet again. Suraj does something curious — he walks into the empty tunnel, just to know what it feels like inside. It grows pitch dark. The walls are damp. A bat flies past. A lizard scuttles by. When he comes out the other side, the bright light dazzles him. On the hillside he sees a flash of orange and gold with a long swishing tail — but it vanishes in a second.
Near the tunnel is a small hut. This belongs to Sunder Singh, the tunnel watchman. He has been resting and now welcomes Suraj warmly, joking, “tell me why you were inspecting my tunnel.” He tells Suraj that the flash of orange was a leopard — “my leopard,” he says fondly — a gentle animal that visits the area each month and means no harm. Sunder Singh lives alone here. His job is to walk through the tunnel before every train and check that the line is clear. He invites Suraj to come back at night to see the night mail pass, and offers to walk him home afterwards.
The next evening, Suraj returns. The two share hot tea and listen to the night birds. Sunder Singh lights his lamp and goes to inspect the tunnel. When he comes back, both of them hear a strange sound from inside — a rhythmic sawing. Sunder Singh knows at once: it is the leopard, and it is inside the tunnel. The night mail will arrive in minutes. If the leopard stays, the train will kill it. Sunder Singh cannot let that happen.
So, axe in hand and lamp held high, he walks into the tunnel, shouting to scare the animal away. Suraj follows close behind, though his throat is too dry to shout at first. They find the leopard crouching on the track, snarling, only a few metres away. Then both of them shout together. Their voices fill the tunnel. The leopard, unsure how many humans are there, turns and disappears into the dark. They check the whole tunnel to be sure it has gone. Just then the rails begin to hum — the night mail is coming. It thunders safely through.
A week later, Suraj and his father are passengers on that very night mail, on the way to Delhi. It is dark outside. As the train nears the tunnel, Suraj stares into the night — and sees the lamp. He cannot see Sunder Singh, but he knows his friend is out there. As the train rushes on, Suraj thinks of the lonely watchman with his lamp, who “would always remain a firefly” lighting up the darkness for steam engines and leopards.
The picture below shows the shape of the whole story — how it rises with wonder, dips into danger, then rises again to a warm ending. Figure 4.1 walks through all five steps in order.
The characters
A character is a person (or animal) in a story. This story has two main human characters and one important animal.
Suraj — the curious boy. He loves trains so much that he travels far just to watch one pass. He is brave and full of questions. He does not just look at the tunnel; he walks through it to know it. When danger comes, he does not run home — he follows Sunder Singh into the dark.
Sunder Singh — the watchman. He lives alone by the tunnel and keeps it safe. He is calm, kind, and quietly brave. He treats the jungle and even the leopard as friends. He risks his own safety to save the leopard’s life, which tells us he is gentle and full of heart.
The leopard — “his” leopard. It is not the villain of the story. Sunder Singh calls it “my leopard.” It is a wild animal that visits the area and means no harm to him. It becomes a danger only by accident — it wanders into the tunnel just before a train is due.
Why the watchman walks into danger — the heart of the story
This is the most important moment, so let us not rush past it. Let us ask why.
A train is minutes away. A leopard — a wild animal with claws and teeth — is sitting inside a pitch-dark tunnel. Most people would simply step back and let the train deal with it. But Sunder Singh picks up his axe and walks straight in. Why would he risk his life for a leopard?
The answer tells us who he really is. First, he feels connected to every living thing in his jungle, even the leopard. He has seen it many times; he calls it “my leopard.” To him it is not a monster but a neighbour. Second, he cannot bear the thought of a needless death. He says simply, “I can’t let that happen.” That one line shows a deep kindness. He would rather face danger himself than let a creature be killed when he could have saved it.
There is also clever thinking in how they win. Look closely: the leopard does not run because the humans are stronger. It runs because, in the dark, it cannot tell how many humans are shouting. When Suraj and Sunder Singh shout together, their voices fill the whole tunnel. The leopard, “uncertain as to how many terrifying humans” are there, decides it is safer to flee. They win with courage and with cleverness, not with force.
Figure 4.2 below shows Sunder Singh’s daily safety system. It explains why one quiet man, with only a flag and a lamp, can protect a whole trainload of strangers.
Why he is called a “firefly” — the message
The story ends with a beautiful image: Sunder Singh “would always remain a firefly” for the travelling thousands. Let us understand exactly why this word fits.
A firefly is a tiny insect that makes its own small light and glows in the dark. Now picture Sunder Singh. He sits alone in a vast, dark jungle at night, holding one small oil lamp. To the hundreds of passengers who flash past in a few seconds, he is just one tiny point of light in a huge darkness — exactly like a firefly. They may never even see his face. But that small light keeps them all safe.
So the word “firefly” carries the message of the whole story. It says that quiet, ordinary people, doing their humble duty without any praise, can be the small lights that protect many. Sunder Singh asks for nothing, yet he guards a whole railway line, night after night. That is a kind of hero we often forget to notice.
Figure 4.3 lays out this idea as a chain. Each box leads to the next, ending in the firefly.
Sunder Singh says about the leopard, 'I can't let that happen.' What do these few words tell us about his character?
They show that Sunder Singh is deeply kind and feels responsible for the lives around him. He would rather walk into danger himself than let the leopard be killed by the train when he had the chance to save it. It is a small line, but it reveals a big heart.
Piece 2: The Poem — “Travel”
The unit also has a short poem called “Travel”, written by the American poet Edna St. Vincent Millay. It is only three stanzas long, but it captures a powerful feeling — the longing to travel.
First, two small words. Cinders are the tiny red, glowing bits of burnt coal that a steam engine throws out — like the glowing sparks from a bonfire. To shriek means to make a sharp, high cry; here the train’s whistle “shrieks.”
Simple meaning, stanza by stanza
Let us go through the poem’s ideas in plain words. (Remember, we are explaining the meaning, not copying the poem.)
Stanza 1 — by day. The speaker says the railway track is “miles away,” and her day is full of voices and noise. Yet, even though no train actually passes near her all day, she still hears its whistle shrieking. The sound is in her mind, because she thinks about trains all the time.
Stanza 2 — by night. At night, when everything is quiet and still, again no train goes by. But she sees the train’s red cinders glowing on the sky, and hears its engine steaming. Once more, the train is not really there — it lives inside her imagination, day and night.
Stanza 3 — the wish. Then she says something surprising. Her heart is warm with the good friends she has made, and she could not ask for better friends. And yet — there is not a single train she would not climb aboard, no matter where it is going. Her love of travel is so strong that even her dear friends cannot hold her back.
Figure 4.4 below gathers these three pictures around the one thing at the centre of the poem — the train the speaker longs to ride.
The speaker and the “why” behind the poem
The speaker is the person whose voice we hear in the poem. Here she is someone who feels a deep, restless pull towards travel and adventure.
Now let us ask the big why. Why does she keep hearing and seeing a train that is not even there?
The answer is the heart of the poem. The train is not just a train. It is a symbol — a picture that stands for something bigger. The train stands for adventure, freedom, and new places. Because the speaker wants those things so badly, her mind paints the train everywhere. By day she “hears” it. By night she “sees” it. The train fills her imagination because her longing for travel never switches off.
And why does the last stanza mention her friends? This is the cleverest part. The poet first tells us the speaker has wonderful friends and a warm heart. We expect her to say she would never leave them. Instead she says she would take any train, anywhere. By placing her love of friends next to her love of travel, the poet shows just how strong that travel-longing is. It is so powerful that even the people she loves most cannot stop her wish to go. That contrast is what makes the ending hit so hard.
In the poem, the train is never actually there — yet the speaker hears and sees it all the time. What does the train really stand for?
The train is a symbol. It stands for adventure, freedom, and the chance to travel to new places. Because the speaker longs for these things so deeply, her imagination fills the day and night with the sound and sight of the train, even though no real train passes by.
Piece 3: The True Account — “Conquering the Summit”
The last piece is not a story or a poem. It is a true account — a piece of writing about a real person and real events. It is about Arunima Sinha, a real Indian mountaineer. Because it is true, her courage feels even more amazing.
A few words first. To amputate means to cut off a part of the body; Arunima had a leg amputated. A prosthetic leg is an artificial leg that helps a person walk. The summit is the very top of a mountain. Resilience means the power to recover and bounce back after a hard blow.
What happens — her real journey
In 2011, Arunima Sinha was a young, fit, national-level volleyball player. Then her life changed in one terrible night. On 11 April 2011, she had a train accident. The hours that followed were “harrowing” — deeply painful. She barely survived, and doctors had to amputate one of her legs. She was given a prosthetic leg and began long, painful physiotherapy.
Most people, lying in a hospital bed with one leg gone, would dream small. Arunima did the opposite. Inspired by an article about Mount Everest, she made a vow that many thought impossible: she would not just learn to walk again — she would climb Mount Everest, the highest mountain on Earth.
To reach this goal, she did the hard, unglamorous work. She completed a basic mountaineering course at the Nehru Institute of Mountaineering, then trained rigorously for eighteen months. She went to Bachendri Pal — the first Indian woman to climb Everest — for guidance. Bachendri Pal believed in her and said something wise: by deciding to climb Everest in such a situation, Arunima had already “conquered the Everest within”; the world would see it later.
On 21 May 2013, after 52 exhausting days of climbing, Arunima Sinha stood on the summit of Mount Everest. She became the first Indian woman amputee to do so. At the top of the world, she felt pride, relief, and a huge sense of achievement. She put up the Indian flag and left a photo of her hero, Swami Vivekananda.
But she did not stop there. By 2019 she had climbed the highest peak on every continent — the famous Seven Summits — finishing with Mount Vinson in Antarctica, again the first female amputee to do it. She wrote her life story in a book called Born Again on the Mountain. Her message is simple: “Never give up and work hard. Always remember your goal and work on it.”
Figure 4.5 shows her journey as a rising line — from her lowest moment in 2011 to the very top of the world.
Why her story matters — the “why” behind her courage
Let us ask the deeper question. Why is Arunima’s achievement so special? After all, many people have climbed Everest.
The answer is that her real fight was not on the mountain. It was inside her own mind. Think about her situation. She had just lost a leg. She was in pain. The easy, “sensible” choice was to give up sport and live a quiet, careful life. Climbing the world’s tallest mountain on a prosthetic leg was not just hard — most people would call it impossible.
This is exactly why Bachendri Pal’s words are the key to the whole piece. She said Arunima had already “conquered the Everest within.” What does that mean? The real Everest — the toughest one — is the mountain of fear and doubt inside us. The moment Arunima decided to try, she had already beaten that inner mountain. Reaching the actual summit two years later was just proof of a victory she had already won in her heart.
So her story is not really about ice and rock. It is about willpower — the power to keep going when everything tells you to stop. That is why she is called a “beacon of hope and resilience”: her life is a light that tells every reader, “If she did that, maybe I can do my hard thing too.”
Bachendri Pal told Arunima she had already 'conquered the Everest within her'. What did she mean by the 'Everest within'?
The ‘Everest within’ means the inner mountain of fear, doubt, and despair after losing her leg. Bachendri Pal meant that the bravest, hardest victory was the decision to try — to refuse to give up. By deciding to climb Everest in such a hard situation, Arunima had already beaten that inner fear. The real mountain was just the proof of it.
How the three pieces connect
These three pieces sit together in one unit because they share one big idea: travel and adventure need curiosity and courage. But they show it in different ways. Let us put them side by side.
| Piece | Type | The adventure | What it teaches |
|---|---|---|---|
| 'The Tunnel' (Ruskin Bond) | Short story | A boy explores a tunnel; a watchman faces a leopard | Curiosity and quiet, everyday courage |
| 'Travel' (Edna St. Vincent Millay) | Poem | A longing to ride any train, anywhere | The deep human pull towards new places and freedom |
| 'Conquering the Summit' (Arunima Sinha) | True account | Climbing Everest and the Seven Summits on a prosthetic leg | Willpower and never giving up on a goal |
Common Mistakes
Some ideas in this unit are easy to get a little wrong. Let us clear up three before they trip you up.
The first one is about the word “firefly”.
Sunder Singh is called a 'firefly' because he is small, weak, or unimportant.
A firefly is a tiny insect, so calling a person a firefly can sound like an insult about being small or unimportant.
Here 'firefly' is a word of praise. A firefly makes its own light in the dark. Sunder Singh, alone in the huge dark jungle with one small lamp, lights the way for trains and keeps thousands of passengers safe. The word celebrates his quiet, brave service — not weakness.
The next one is about the train in the poem “Travel”.
In the poem 'Travel', the speaker really hears and sees an actual train passing near her house.
The poem describes the whistle and the cinders so vividly that it sounds like a real train is right there.
The poem clearly says no train passes by — by day or by night. The track is 'miles away'. The speaker only *imagines* the train because she longs to travel so much. The train is a picture in her mind that stands for adventure and freedom.
The last one is about Arunima Sinha.
Arunima Sinha's greatest victory was simply that she was a strong climber who reached the top of Everest.
Reaching the summit of Everest is a huge physical feat, so it seems natural to call that her main achievement.
Her greatest victory was inside her mind. As Bachendri Pal said, she 'conquered the Everest within' the moment she *decided* to try, despite losing a leg. Her story is about willpower and refusing to give up — the physical climb was the proof of an inner victory she had already won.
Quick Check
Let us see how well the three pieces have settled in. Try these short questions.
In 'The Tunnel', why does Sunder Singh walk into the tunnel to face the leopard?
Sunder Singh feels connected to every creature in his jungle, even the leopard. The night mail is minutes away, and if the leopard stays in the tunnel it will be run over. He says, “I can’t let that happen,” and walks in to scare it out and save its life.
Why is Sunder Singh called a 'firefly' at the end of the story?
A firefly makes its own small light in the dark. Sunder Singh sits alone in the huge dark jungle with one oil lamp, guiding trains and warning the leopard. To the thousands rushing past, he is one tiny point of light keeping them safe — exactly like a firefly.
In the poem 'Travel', what does the train really stand for?
No real train passes by — the track is ‘miles away’. The train is a symbol. It stands for adventure and freedom. Because the speaker longs to travel so much, she imagines the train’s whistle and cinders by day and by night.
What did Bachendri Pal mean when she said Arunima had 'conquered the Everest within'?
The ‘Everest within’ is the inner mountain of fear and doubt. The hardest, bravest step was Arunima’s decision to try, despite her injury. By deciding, she had already conquered that inner fear — the real climb was just the proof.
Practice
Now try writing some answers yourself. Attempt each one first, then open the solution to check.
Easy
In one or two sentences, why does Suraj walk through the dark tunnel in 'The Tunnel'?
Suraj is a curious boy who loves trains. He walks through the dark tunnel simply because he wants to know what the inside of a tunnel really feels like. It is not to get anywhere — it is his sense of adventure and curiosity.
Name the three pieces in this unit and their writers (or, for the third piece, who it is about).
- “The Tunnel” — a short story by Ruskin Bond.
- “Travel” — a poem by Edna St. Vincent Millay.
- “Conquering the Summit” — a true account about the mountaineer Arunima Sinha.
Medium
Why is Sunder Singh called a 'firefly' at the end of 'The Tunnel'? Explain in 3–4 sentences.
A firefly is a tiny insect that makes its own small light and glows in the dark. Sunder Singh sits alone in the huge, dark jungle at night with just one small oil lamp. That one light guides the trains and warns the leopard, keeping everyone safe. To the thousands of passengers who flash past in the dark, he is just one tiny point of light — exactly like a firefly. The word praises how one humble, faithful man quietly protects so many people.
In the poem 'Travel', the speaker says she has warm and wonderful friends, yet she would still take any train, anywhere. Why does the poet mention her friends? Write 3–4 sentences.
The poet mentions the friends to show how strong the speaker’s love of travel is. First we are told she has the best of friends and a warm heart, so we expect her to say she would never leave them. Instead, she says she would take any train, no matter where it goes. By placing her love of friends right next to her longing for travel, the poet makes the longing feel even more powerful — it is so strong that even the people she loves most cannot hold her back.
Challenge
Vocabulary: explain the words 'amputated', 'prosthetic leg', and 'resilience' in your own simple words, with a tiny example for each.
- Amputated — when a part of the body is cut off, usually because of a serious injury or illness. Example: After the accident, one of Arunima’s legs had to be amputated.
- Prosthetic leg — an artificial leg that helps a person walk after losing their real leg. Example: With her prosthetic leg, Arunima learned to walk and then to climb.
- Resilience — the power to recover and keep going after a hard blow. Example: Arunima showed great resilience by chasing a huge dream right after losing her leg.
The three pieces — 'The Tunnel', 'Travel', and 'Conquering the Summit' — are placed together in one unit called 'Travel and Adventure'. Explain what idea they share, using one example from each piece.
All three pieces are about the spirit of travel and adventure, which needs both curiosity and courage.
- From ‘The Tunnel’: Suraj’s curiosity makes him walk through a dark tunnel just to know it, and Sunder Singh’s courage makes him face a leopard to keep the train safe.
- From ‘Travel’: the speaker’s heart longs so deeply for adventure that she imagines a train day and night and says she would ride any train, anywhere.
- From ‘Conquering the Summit’: Arunima Sinha’s willpower drives her to climb Mount Everest, and later the Seven Summits, on a prosthetic leg.
So the made-up story and poem show the feeling of adventure, while Arunima’s true account shows real-life courage in action. Placed together, they teach that the most exciting and rewarding experiences belong to those who stay curious and never give up.
Summary
- “The Tunnel” by Ruskin Bond is about Suraj, a boy who loves trains, and Sunder Singh, the lonely watchman of a jungle tunnel.
- Suraj’s curiosity leads him to explore the dark tunnel and meet Sunder Singh. The next evening, the two work together to drive a leopard out of the tunnel before the night mail can kill it.
- Sunder Singh faces danger to save the leopard because he feels connected to every creature in his jungle and says, “I can’t let that happen.” They win by shouting together, so the leopard cannot tell how many humans are there.
- At the end, Sunder Singh is called a “firefly” — one small, faithful light in the huge dark jungle, quietly keeping thousands of passengers safe.
- The poem “Travel” by Edna St. Vincent Millay shows a deep longing to travel. The speaker imagines a train’s whistle by day and its cinders by night, and says she would take any train, anywhere. The train is a symbol for adventure and freedom.
- The true account “Conquering the Summit” is about Arunima Sinha, who lost a leg in a train accident, then climbed Mount Everest (2013) and the Seven Summits (by 2019) on a prosthetic leg. Her real victory was conquering the “Everest within” — her own fear and doubt.
- All three pieces share one idea: travel and adventure need curiosity and courage, and the richest experiences belong to those who keep exploring and never give up.
- New words to remember: cinders (glowing bits of burnt coal), summit (the top of a mountain), amputated (cut off), prosthetic leg (an artificial leg), resilience (the power to bounce back).
What’s Next
You have seen adventure in three forms — a curious boy, a longing poet, and a fearless climber. In the next unit, Unit 5 — Bravehearts, we stay with courage but turn the spotlight fully onto it. Just as Sunder Singh and Arunima Sinha showed quiet and fierce bravery here, Unit 5 brings stories of brave hearts who stand up and do the right thing. See you there.
