Lost in McDougal's Cave

The picnic excursion to McDougal's Cave, a vast limestone labyrinth on the Mississippi River, turns into a harrowing ordeal for Tom Sawyer and Becky Thatcher. What begins as a playful hide-and-seek among the cave's famous chambers—named "The Drawing-Room," "The Cathedral," and "Aladdin's Palace"—ends in a desperate struggle for survival when the two children wander away from the main party and become hopelessly lost in the cave's uncharted depths. The episode constitutes the novel's most sustained test of courage, resourcefulness, and endurance, transforming Tom from a mischievous boy into a protector capable of facing death itself.

The Descent into the Labyrinth

Tom and Becky, tiring of the group's frolics, drift down a sinuous avenue holding their candles aloft, reading the names and mottoes frescoed on the walls in candle-smoke. They pass beyond the familiar tourist sections into a part of the cave whose walls are bare. Tom squeezes his small body behind a waterfall-like limestone formation to illuminate it for Becky and discovers a steep natural stairway enclosed between narrow walls. Seized by the ambition to be a discoverer, he leads Becky down this hidden passage, making a smoke-mark for guidance. They wind deeper into the secret depths, finding a spacious cavern hung with stalactites "of the length and circumference of a man's leg," a bewitching spring with a basin incrusted with glittering crystals, and a subterranean lake whose dim length is lost in shadow. A swarm of bats, disturbed by the lights, attacks them, knocking out Becky's candle, and they flee into a new corridor to escape. When they finally stop to rest, Becky realizes with a chill that she has not heard the others for a long time. Tom admits they are "away down below them" and cannot tell how far north, south, east, or west they have gone. He tries to find the way back, but every new opening looks strange. His confident reassurances—"Oh, it's all right. This ain't the one, but we'll come to it right away!"—grow hollow as failure follows failure. At last, a certain indecision in his manner reveals the fearful truth to Becky: he cannot find the way back. He had made no marks beyond the first one.

Starvation, Darkness, and Despair

The children's ordeal unfolds in the absolute darkness of the cave, broken only by the dwindling light of their candles. Tom, realizing the need to economize, blows out Becky's candle, a gesture whose grim meaning needs no words. Fatigue overwhelms them; Becky's frail limbs refuse to carry her farther, and she falls asleep in Tom's arms. When she wakes, she speaks of a beautiful country she saw in her dream, and Tom fears she is losing hope. They find a spring and Tom fastens his last candle to the wall with clay. The only food they have is a piece of wedding-cake Becky saved from the picnic, which they divide. Tom tells her the terrible truth: "that little piece is our last candle!" They watch the flame rise and fall, climb the thin column of smoke, linger at its top a moment, and then—utter darkness. They lose all track of time, sleeping and waking in a stupor of hunger and misery. Tom believes it must be Tuesday, then Wednesday or Thursday, perhaps even Friday or Saturday. He shouts for help, but the distant echoes sound so hideously that he stops. At one point, he hears a faint, far-off shout and answers it, leading Becky toward the sound, but the voices grow more distant and then cease altogether, leaving them in heart-sinking misery. Becky sinks into a dreary apathy, telling Tom to go on exploring if he chooses but imploring him to return and speak to her, and to stay by her and hold her hand when the end comes.

The Encounter with Injun Joe

In a final desperate attempt to find an escape, Tom takes a kite-line from his pocket, ties it to a projection, and explores a side passage. At the end of twenty steps, the corridor ends in a "jumping-off place." As he kneels and reaches around a corner, a human hand holding a candle appears from behind a rock not twenty yards away. Tom lifts a glorious shout, and the hand is followed by the body it belongs to—Injun Joe's. Tom is paralyzed. The murderer, whose testimony Tom had contradicted in court, takes to his heels and disappears. Tom realizes that the echoes must have disguised his voice, saving his life. He is careful to keep from Becky what he has seen, telling her he only shouted "for luck." The encounter deepens his terror, but hunger and wretchedness rise superior to fear, and he resolves to risk another exploration.

The Escape and Rescue

Tom's final exploration succeeds where all others failed. Following a third avenue to the fullest stretch of his kite-line, he glimpses a far-off speck that looks like daylight. Dropping the line, he gropes toward it, pushes his head and shoulders through a small hole, and sees the broad Mississippi River rolling by. He returns to Becky, who is too weak and despairing to believe him at first, but he labors with her until she gropes to where she actually sees the blue speck of daylight. Tom pushes his way out of the hole and helps her out. They sit and cry for gladness. Some men in a skiff pass by; Tom hails them and tells their story. The men are incredulous at first, for the children are five miles down the river below the valley where the cave is located, but they take them aboard, row to a house, give them supper, and bring them home. The news of their rescue sets off a wild celebration in St. Petersburg, with bells pealing and the entire population thronging the streets. The three days and nights of toil and hunger leave both children bedridden for days afterward, but Tom recovers more quickly than Becky, who looks as if she has passed through a wasting illness.

Consequences and Aftermath

The cave ordeal has profound consequences for the story's resolution. Judge Thatcher, to prevent any future tragedies, has the cave's big door sheathed with boiler iron and triple-locked. When Tom learns of this, he turns white as a sheet, for he knows that Injun Joe is still inside. A rescue party finds the murderer dead at the door, starved to death, his knife broken from futile attempts to hack through the door's foundation beam. The discovery of Injun Joe's body frees Tom from the "vast weight of dread" that has lain upon him since he testified in court. More importantly, Tom realizes that the treasure he and Huck Finn had been seeking must be hidden in the cave. He leads Huck back through the secret exit, and they find the gold—over twelve thousand dollars—buried under a cross marked in candle-smoke on a rock. The cave, which nearly killed Tom and Becky, thus becomes the source of their wealth and the foundation of their future adventures as robbers. The ordeal also cements Tom's reputation as a hero in the eyes of Judge Thatcher, who declares that no commonplace boy could have saved his daughter, and who begins to plan for Tom's education at the National Military Academy and law school.
