Dalton's furnace

Dalton's furnace is the basement furnace Bigger Thomas turns to when he decides to conceal Mary Dalton’s death by burning her body. It is both a practical instrument and a stubborn material obstacle: its fire seems to promise secrecy, but the body will not fit inside as he first tries to dispose of it. Later, the furnace’s coals and ashes keep the concealed act present in Bigger’s mind, making the appliance a recurring point where attempted erasure meets the persistence of evidence.

Setting and Operation

The furnace stands in the basement of the Dalton family residence. Bigger reaches it after carrying a heavy trunk downstairs and pausing to listen to its draft. Red coals show through the cracks in its door; when he opens it, the fire appears to offer a way to destroy what the trunk contains. The scene establishes the furnace through ordinary working features—the door, the draft, the coals, and the coal lever—before those features become bound to Bigger’s attempt at concealment.

The furnace operates as a household appliance, but its scale and limits matter to the scene. Bigger pushes Mary into the fire feet first, yet the body will not go fully inside. Although the clothes catch fire and smoke fills the furnace, her head remains outside the door. The fire is therefore not an effortless solution: the furnace’s opening and the body’s failure to pass through it interrupt Bigger’s plan and force him to act again.

Use in Bigger’s Attempt at Concealment

Bigger’s decision to use the furnace follows his fear that the body will be discovered. He regards burning it as the safest course, opens the furnace, and transfers Mary from the trunk. When the body cannot be pushed completely inside, he leaves the basement task unfinished only long enough to find another means of making it fit. He uses a hatchet to separate the head, then wraps it in newspaper and uses the bundle to push the rest of the body farther into the furnace. He puts the head and the hatchet inside as well.

Bigger then attends to the furnace as an operating machine. At four o’clock, he considers whether there will be enough coal and whether anyone will come down before ten the next morning. He wipes his knife, puts paper into the fire, places more coal through the chute by pulling the lever, and closes the lower door after the body is covered. These practical steps show how the attempt depends on time, fuel, and the furnace’s draft, not just on the initial decision to burn the evidence. He shuts the trunk and moves it to a corner, believing he has left nothing that will betray him.

The Furnace After the Night

The furnace continues to demand Bigger’s attention the next morning. After Peggy has left the basement, he searches the room and finds a small blood-stained piece of newspaper near the furnace door. He worries that Peggy may have seen it, picks it up, and looks inside. The body is gone, yet the glowing coals appear to hold its bent outline in his vision. When the draft pulls the paper from his fingers, it disappears into the heat. The small remnant is removed, but this does not free Bigger from imagining what the fire has hidden.

Later, Bigger again approaches the furnace and looks through the bright cracks in its door. He pulls the coal lever, hears coal rattle down the chute, and sees the embers darken as the coal supply is shut off. Opening the lower door, he sees that ashes have accumulated. He recognizes a further task: to shovel them out in the morning and check for unburnt bones. Thus, the furnace has not ended the concealment work. Its use creates a continuing obligation to manage the remains and inspect what the fire may not have consumed.

Narrative Significance

The furnace changes from a seemingly available means of concealment into an object whose physical limits and residues shape Bigger’s actions. It cannot simply absorb the body at the first attempt; its capacity, fire, and need for fuel determine the sequence of what he does next. Later, ashes, a scrap of newspaper, and the possibility of unburnt bones turn its ordinary maintenance into part of his effort to keep the crime hidden.

Its recurrence also gives the concealment attempt a material presence after the initial act. Bigger’s attention returns to the same door, draft, lever, coals, and ashes, while his perception of the coals carries the body’s outline even after it has disappeared from view. The furnace can alter what remains visible, but it cannot make Bigger’s knowledge disappear. In the plot, it is therefore not only the instrument of an attempted destruction of evidence but also the place where the limits and ongoing consequences of that attempt repeatedly come into focus.
