The chapter recounts the daring escape of five prisoners of war from Richmond during the American Civil War. Led by engineer Cyrus Smith, the group—including reporter Gideon Spilett, servant Neb, sailor Pencroff, and young Herbert Brown—seizes the opportunity of a violent storm to steal a balloon and flee the besieged city. After a perilous five-day aerial voyage, the balloon crashes on an unknown island, leaving Cyrus Smith missing and his companions stranded.
Chapter 4
III
The castaways realize they are stranded on a small, barren island after Cyrus Smith is swept away by a wave. Despite desperate searches and calls through the night, they find no trace of him. At dawn, the fog lifts to reveal a larger landmass to the west, separated by a channel. Neb bravely swims across, while the others wait for low tide to ford the channel, hoping to find Smith alive.
Chapter 5
IV
Pencroff and Herbert explore the coast, find a river, gather wood, and discover a rocky shelter they call the Chimneys. They collect lithodomes for food and prepare a timber float to transport firewood, while awaiting the return of their companions.
Chapter 6
Arranging the Chimneys
The castaways work to make the Chimneys habitable, but face a crisis when Pencroff realizes he has lost his matchbox. A desperate search for the matches proves fruitless. Neb and Gideon Spilett return from their search for Cyrus Smith without finding him, deepening the group's despair. Herbert discovers a single remaining match in his pocket, which Pencroff uses to successfully start a fire. The chapter ends with the first meal on the island, while Neb continues to search for his master through the night.
Chapter 7
The Castaways' Inventory
The castaways take stock of their meager possessions after the balloon crash, finding only the clothes on their backs, Spilett's watch and notebook, and no tools or weapons. They decide to wait a few days at the Chimneys before exploring the island. Neb, refusing to believe Cyrus Smith is dead, searches the coast. Herbert and Pencroff venture into the forest to hunt, using improvised cudgels and later a fishing line with hooks made from thorns to catch tetras. They return with game, having observed the virgin wilderness and traces of wild beasts.
Chapter 8
VII
As a violent storm rages, the colonists worry about Neb's absence and debate the fate of Cyrus Smith. Gideon Spilett expresses doubt that Smith and Top have drowned, while Pencroff believes they have perished. During the night, Top's barking is heard, and the dog arrives alone at the Chimneys, leading the group into the storm to search for his master.
Chapter 9
VIII
The chapter opens with Neb, Herbert, and Pencroff constructing a litter to transport the injured Cyrus Smith. Smith awakens and learns of the events following his disappearance. He questions the mysterious footprints that led to his discovery, but ultimately concludes that he must have walked in a somnambulistic state, guided by Top. The group returns to the Chimneys, only to find it devastated by the storm, with their fire and supplies destroyed.
Chapter 10
IX
Cyrus Smith is recovered and the castaways face the challenge of making fire. Pencroff's attempts to create fire by rubbing wood fail, but the group's confidence in the engineer remains unshaken. Smith outlines their situation: they must determine whether they are on a continent or an island. Plans are made to ascend the mountain the next day to survey the land. Meanwhile, Pencroff, Herbert, and Neb go hunting in the forest, while Smith and Spilett examine the shore.
Chapter 11
The Ascent of the Volcano
The castaways, led by Cyrus Smith, embark on an expedition to climb the mountain and determine whether they are on an island or a continent. Using a makeshift lens, Smith starts a fire, and the group ascends through volcanic terrain, encountering wildlife such as tragopans and moufflons. After a challenging climb, they reach the summit at night, and Smith confirms they are on an island as the moon reflects on the surrounding sea.
Chapter 12
Chapter XI: At the Summit of the Cone
The colonists ascend the volcano's summit to survey their island. They confirm it is an isolated island with no other land in sight, and no signs of human habitation. Cyrus Smith estimates the coastline at over a hundred miles. They name the island's features, including Union Bay, Washington Bay, Mount Franklin, Lake Grant, and finally the island itself as Lincoln Island, after the great American president. The group resolves to act as colonists rather than castaways.
Chapter 13
Exploration of Lake Grant
The colonists explore the island, regulating their watches and naming geographical features. They discover Lake Grant, encounter wildlife including mountain pheasants and agoutis, and gather mineral resources for future projects.
Chapter 14
XIII
The colonists begin their work of civilization on Lincoln Island, starting with the manufacture of tools and pottery. They make bows and arrows, build a brickkiln, and create pottery for cooking. The engineer discovers a plant that can be used as tinder. The chapter ends with an astronomical observation to determine the island's latitude.
Chapter 15

During the exploration, Top becomes agitated and dives into the lake, revealing an enormous aquatic creature.
Chapter 18
XVII
Cyrus Smith devises a plan to lower the level of Lake Grant by blasting the granite wall with nitroglycerine, which he manufactures from natural resources including schistous pyrites, dugong fat, seaweed, and saltpetre. The colonists work together to produce sulphuric acid, soap, glycerine, and finally nitroglycerine, setting the stage for the explosion.
Chapter 19
XVIII
The colonists successfully lower the lake level using nitroglycerine, revealing an old outlet that leads to a vast subterranean cavern. They explore the passage, discovering a magnificent granite chamber which they name 'Granite House.' The chapter ends with the mystery of Top's barking at a deep well, hinting at unknown presences.

XXIII
The colonists discover a bullet in a young peccary, proving that a gun has been fired on Lincoln Island within three months. This raises urgent questions about possible inhabitants, whether friends or foes. Pencroff proposes building a bark canoe in five days to explore the Mercy River. Meanwhile, Herbert and Neb capture a turtle, but it mysteriously disappears when the tide rises, leading Smith to offer a plausible but perhaps insufficient explanation.
Chapter 26
Trial of the Canoe
The colonists complete their canoe and set out to explore the western coast. They discover a large box buoyed by barrels washed ashore at a point they name Jetsam Point. Towing it back to Granite House, they open it to find various manufactured goods, though Pencroff is disappointed at the lack of tobacco. The discovery prompts a plan for a thorough exploration of the island. That evening, Herbert asks Cyrus Smith to read from the Bible, and Pencroff suggests opening it at random; the verse found is Matthew 7:8: 'For everyone that asketh, receiveth; and he that seeketh, findeth.'

XXVI
The colonists set out to reach the west coast, navigating through dense forest and encountering monkeys, wild boars, and other wildlife. They discover a new watercourse they name Fall River, and upon reaching the coast, find a forested shoreline unlike the rocky east coast. They continue toward Reptile End, where they camp in a jaguar's cave after Gideon Spilett kills the beast. The chapter ends with a bamboo fusillade from the campfire scaring off predators.
Chapter 29
XXVII
The colonists explore the southern coast of Lincoln Island in search of signs of a shipwreck, finding only a natural harbor they name Balloon Harbor. They return to the Mercy at midnight to find their canoe drifting downstream, which they recover, only to discover upon reaching Granite House that the ladder is missing.
Chapter 30
XXVIII
The colonists return to Granite House to find the ladder missing and the dwelling seemingly occupied. After a night at the Chimneys, they discover monkeys have taken over their home. They attempt to drive them out, but the monkeys retreat inside. The engineer suggests entering through the old weir, but before they can, the monkeys flee in panic, and the ladder is thrown down to them. Inside, they capture a large orangutan, which Cyrus Smith decides to keep as a servant.
Chapter 31
Projects and Progress on Lincoln Island
The colonists, having reclaimed Granite House from the monkeys, focus on several key projects: building a drawbridge over the Mercy to isolate Prospect Plateau, constructing a corral for woolly animals, and establishing a poultry yard. They capture a pair of onagers (wild asses) and successfully harness them to a cart, using it to retrieve the balloon envelope from Balloon Harbor. The chapter details the engineering of the bridge, the domestication of the onagers, and the ongoing preparations for winter and self-sufficiency.
Chapter 32
Clothing, Corral, and Cultivation
The colonists devote the first week of January to making clothing and boots from seal leather. Smith manufactures pyroxyline as a substitute for gunpowder. They clear land on Prospect Plateau, gather wild vegetables, and fish and hunt turtles for food. Jup is trained as a domestic servant. In late January, they begin constructing a corral at the foot of Mount Franklin to contain moufflons and goats, completing it in three weeks. A grand hunt on February 7 successfully drives thirty moufflons and a dozen wild goats into the corral. The chapter also covers road building, cultivation of wild plants, and the ongoing improvement of their settlement.
Chapter 33
Bad Weather and New Discoveries
During a week of violent storms in early March, the colonists take shelter in Granite House and use the time to improve their living conditions. Cyrus Smith builds a hydraulic elevator to replace the long ladder, and after several attempts, successfully produces glass for windows and tableware. Herbert discovers a cycad, or 'bread tree,' whose edible pith provides a new food source. The colonists also discuss the exact position of Lincoln Island, and upon consulting an atlas, they find Tabor Island marked nearby. Pencroff proposes building a boat to visit it, a plan that is agreed upon for the following October.
Chapter 34
Ship building
The colonists begin constructing a thirty-five-foot sloop to visit Tabor Island. They harvest a second crop of corn, discover wild tobacco, and a dead whale washes ashore with a harpoon from the Vineyard. The whale is processed for oil and whalebone, and the engineer devises whalebone traps for winter. The chapter ends with Pencroff receiving a surprise gift of tobacco.
Chapter 35
Winter Preparations and the Albatross Message
As winter sets in, the colonists focus on making warm clothing by felting moufflon wool using a fulling mill powered by the waterfall. Pencroff persists in his plan to sail to Tabor Island, despite Smith's concerns. They capture an albatross and send a message in a waterproof bag, hoping it reaches the New York Herald. Smith investigates Top's barking at the well but finds nothing, though he remains suspicious.
