1. About the Poet — Carl Sandburg
Carl Sandburg (January 6, 1878 – July 22, 1967) was an American poet, journalist, and biographer. Born in Galesburg, Illinois, to Swedish immigrant parents, he worked many jobs — farm labourer, milk delivery driver, hotel servant — before emerging as one of America's most celebrated poets.
- He is closely associated with the Imagist movement in poetry, which emphasised precise, clear images over abstract ideas. The motto of Imagism: "Show, don't tell."
- Sandburg is sometimes called the "Poet of the American City" — his famous poem "Chicago" praised the raw energy of industrial city life.
- He wrote a six-volume biography of Abraham Lincoln that won the Pulitzer Prize.
- "Fog" (1916), from the collection Chicago Poems, is his most anthologised poem and a perfect example of Imagist economy — saying the maximum with the minimum.
- His poetry was deeply influenced by urban life, nature, ordinary working people, and the rhythms of American speech.
2. Central Idea of the Poem
In just six lines, Sandburg captures the arrival, stay, and silent departure of fog over a city harbour. He uses the extended metaphor of a cat to describe fog. Just as a cat moves in silently on soft paws, pauses to observe its surroundings, and then walks away without any fuss, fog too arrives imperceptibly, lingers for a while surveying the harbour and the city below, and then quietly disappears.
The poem celebrates nature's quiet power — fog does not storm in; it creeps in gently. It also reminds us that nature is impermanent and indifferent: the fog does not stay; it simply "moves on." The poem is a meditation on how nature — even in the middle of a busy city — operates on its own terms, silent and unhurried.
3. Line-by-Line Analysis
Line 1: "The fog comes"
The poem opens with a simple declarative sentence. The word "comes" is deceptively plain — it tells us the fog arrives, but it tells us nothing about sound or violence. This is deliberate. The fog does not crash in or pour in; it simply comes. The present tense gives the poem an immediacy — this is happening now, before our eyes. There is also a sense of the inevitable: fog does not ask permission to arrive.
Line 2: "on little cat feet."
This is the heart of the poem and its most celebrated image. Sandburg compares the movement of fog to the soft paws of a cat. The word "little" is important — it conveys smallness, gentleness, and something almost endearing. A cat's feet make no sound; they are padded and light. This is the perfect vehicle for fog, which arrives without warning, without noise, and without announcement. The comparison also captures the stealth and mystery of fog — you do not see it coming; it is simply there. The phrase is also an example of tactile imagery — we almost "feel" the soft approach of fog through this image of cat feet.
Line 3: "It sits looking"
The fog has now arrived and paused. The verb "sits" is crucial — a cat sits when it is observing something. It is not lying down (that would mean resting or sleeping) and it is not standing (that would mean readiness to pounce). Sitting is the posture of a calm, watchful observer. The fog, too, is presented as an observer — it watches over the harbour and city without interfering. The word "looking" gives the fog agency and intelligence: it is aware; it surveys; it is present. This is personification — fog does not literally look, but the image makes it feel alive and conscious.
Line 4: "over harbour and city"
The fog has enveloped two distinct spaces: the harbour (the water, the boats, the sea-world) and the city (streets, buildings, human activity). Together these two words span the entire world of human life at that location — sea and land, nature and civilisation. The fog covers both indifferently. The order is significant: harbour comes before city — fog typically rolls in from water first. This gives the poem a sense of natural, directional movement.
Line 5: "on silent haunches"
Haunches are the hind legs and rump of an animal. When a cat sits, it tucks its haunches beneath its body, resting on its back legs. This is an extremely precise and visual image. Sandburg is telling us the fog is crouched — paused, temporarily settled, in the posture of a cat at rest. The word "silent" reinforces the most important quality of both fog and cat: silence. In a busy city with a noisy harbour, this fog-cat sits absolutely quietly. The silence is not empty — it is loaded, watchful, deliberate.
Line 6: "and then moves on."
The final line is the most profound in the poem. Everything that arrived — the fog, the cat, the sense of presence — now departs. The phrase "and then" signals a natural, unhurried transition. "Moves on" is the linguistic opposite of "comes" from line 1. The fog came; now it moves on. There is no drama, no climax, no tragedy in this departure. Fog — like a cat — is independent and indifferent. It owes nothing to the city or the harbour. It stays as long as it pleases and leaves without explanation. This is the poem's deepest statement: nature is impermanent and self-determining.
4. The Extended Metaphor — Fog as Cat
An extended metaphor is a comparison that is maintained and developed throughout an entire poem or prose passage. Sandburg compares fog to a cat in every line. Here is the full point-by-point comparison:
| Quality of a Cat | Quality of Fog |
|---|---|
| Moves silently on soft paws | Fog arrives without sound or announcement |
| Appears suddenly — you don't notice its approach | Fog creeps in imperceptibly |
| Sits and watches the world from a distance | Fog hovers over and covers the city without disturbing it |
| Independent — stays as long as it likes | Fog lingers for its own duration |
| Leaves without warning or reason | Fog lifts and disappears quietly |
| Mysterious, unpredictable | Fog is mysterious — you cannot predict when it will come or go |
| Sits on haunches — crouching, low, covering the ground | Fog sits low over water and city, enveloping them |
5. Themes of the Poem
- Nature's quiet power: The fog does not need to announce itself or dominate dramatically. It has power simply by being there — enveloping everything in silence. This is a quieter, more pervasive kind of power than a storm.
- Impermanence: The fog comes and moves on. Nothing in nature is permanent. The poem teaches us that even when something covers the whole world (harbour and city), it will eventually pass. This is a gentle philosophical message.
- The city and nature coexisting: In the poem, fog — a natural phenomenon — quietly overlays a city and harbour — symbols of human civilisation. Neither destroys the other. They simply coexist for a moment, and then the fog departs. This reflects a peaceful relationship between nature and urban life.
- Silent observation: The fog (and the poet) is an observer, not a participant. This detached, watchful tone reflects the Imagist ideal of presenting a clear picture without sentimentality or moral judgement.
6. Tone and Mood
- Tone (poet's attitude): Quiet, calm, detached, observational. Sandburg is not emotional about the fog — he simply records its movement with precision and economy. There is a sense of gentle wonder.
- Mood (reader's feeling): Peaceful, mysterious, slightly dreamlike. The fog-world the poem creates feels soft and muted — as if the world has been wrapped in cotton wool. There is a slight melancholy in the fog's departure ("and then moves on") but no grief.
7. Poetic Devices — Complete List
- Extended Metaphor: The fog is compared to a cat throughout all 6 lines — "little cat feet," "sits," "haunches," "moves on." The metaphor is never broken.
- Personification: The fog is given animal-like qualities (sitting, looking, moving on) — it is treated as a living, conscious creature with agency.
- Visual Imagery: "sits looking / over harbour and city" — we can picture the fog spread like a crouching animal over the landscape.
- Tactile Imagery: "little cat feet" — we almost feel the soft, padded, light touch of the fog as it arrives.
- Free Verse: There is no rhyme scheme and no fixed metre. This mirrors the free, unrestrained movement of both fog and cat.
- Economy of Language (Brevity): The poem uses only 34 words to convey a complete experience. Every single word carries weight — none is decorative.
- Haiku-like Quality: The poem resembles a Japanese haiku in its brevity, its focus on a single moment in nature, and its avoidance of commentary.
- Enjambment: Lines run into each other without a full stop — "The fog comes / on little cat feet" and "It sits looking / over harbour and city / on silent haunches" — creating a sense of continuous, unbroken movement.
- Symbolism: The cat is a symbol of silent independence, mystery, and unpredictability — all qualities that make it the ideal symbol for fog.
- Alliteration: "sits … silent" — both words in lines 3 and 5 begin with the 's' sound, which itself sounds soft and hushed, reinforcing the silence of fog.
- Simplicity as Style: The absence of complex vocabulary is itself a device. Plain words ("comes," "sits," "looks," "moves") make the poem accessible and universal, placing all the weight on the central image.
- Transferred Epithet (implied): "silent haunches" — silence belongs to the overall approach of the fog, but it is attributed here specifically to the haunches, a detail that intensifies the hush of the image.
8. Word Meanings
- Fog: a thick cloud of tiny water droplets that hangs close to the ground, reducing visibility.
- Little cat feet: the soft, padded paws of a cat; here used metaphorically for the silent movement of fog.
- Sits: to rest in a settled position; used here to describe how fog hovers and lingers.
- Looking: watching, observing; the fog is personified as something that watches over the city.
- Harbour: a sheltered area of water near land where boats and ships dock; also spelled "harbor."
- Silent: making no sound; completely quiet.
- Haunches: the hind legs and thighs of an animal, especially the region of the hip and buttock; when a cat sits on its haunches it is in a low, crouching position.
- Moves on: departs quietly; continues its journey; leaves without fuss.
- Imagist: relating to Imagism, a literary movement that valued precise imagery and clear, economical language over abstract ideas.
- Free verse: poetry that does not follow a regular rhyme scheme or metre.
- Extended metaphor: a metaphor that is developed and sustained over several lines or an entire poem.
Sandburg sees fog as a gentle, mysterious, and temporary visitor. He does not find it threatening or gloomy. Instead, he compares it to a cat — an animal associated with silence, grace, and independence. The fog arrives quietly, surveys the city and harbour, and moves on without causing any disturbance. Sandburg's treatment of fog is calm and appreciative; he admires its silent power and its ability to cover an entire city without a sound.
The poet describes the arrival of fog by comparing it to a cat walking in on little cat feet. Just as a cat moves on soft, padded paws without making any sound, the fog arrives silently and imperceptibly. It does not announce itself; it simply appears. The phrase "little cat feet" emphasises both the silence and the lightness of fog as it creeps in over the city and harbour.
The central image of the poem is the fog as a cat. This extended metaphor is developed across all six lines. In lines 1–2, the fog's silent arrival is compared to a cat coming in on little cat feet. In lines 3–5, the fog's hovering over the city is compared to a cat sitting on its haunches and looking around. In line 6, the fog's departure is described as "moving on," just as a cat quietly walks away. Every aspect of the fog's behaviour — its arrival, its pause, its departure — is captured through the single sustained image of a cat.
Yes, the poet appears to admire the fog. There is no negative language in the poem. He compares fog to a cat — an animal that is traditionally admired for its grace, silence, and mystery. The tone of the poem is calm and appreciative rather than fearful or critical. The fact that Sandburg chose to write an entire poem about fog — devoting all six lines to a single, carefully crafted image — suggests deep respect and fascination for this natural phenomenon. The fog is presented as something beautiful and self-sufficient.
An imagist poem presents a single, clear, precise image without commentary or moralising. "Fog" is a perfect imagist poem because it does exactly this. Sandburg does not explain what the fog means, does not tell us how to feel, and does not draw a lesson. He simply presents the fog through the image of a cat in six spare, economical lines. The language is plain and direct. There is no sentimentality and no abstraction. The reader is given a vivid picture and left to respond to it independently. This is the Imagist ideal: the image itself is the poem.
The poet chose a cat because the qualities of a cat match the qualities of fog more precisely than any other animal would. A dog, for instance, is loud and obvious; an elephant is large and dramatic; a bird is fast and visible. A cat, however, is known for its stealth, silence, independence, and ability to move without being noticed. It arrives and departs on its own schedule and does not need human direction. Fog shares all these qualities — it comes silently, lingers as long as it chooses, and then disappears without warning. The cat is the perfect metaphor for fog.
The fog comes
on little cat feet.
It sits looking
over harbour and city
on silent haunches
and then moves on.
(a) What does the fog come on?
The fog comes on "little cat feet" — meaning it arrives silently and softly, like a cat padding in on its tiny, padded paws.
(b) What two places does the fog look over?
The fog looks over the harbour (the sheltered water area where ships dock) and the city (the urban landscape with streets and buildings).
(c) What are "silent haunches"?
Haunches are the hind legs and rear of an animal. When a cat sits, it rests on its haunches. "Silent haunches" means the fog is crouched, motionless, and completely quiet — like a cat sitting and watching without making a sound.
(d) What poetic device is used in the line "on little cat feet"?
The poetic device used is metaphor — specifically, the fog is being compared to a cat (without using "like" or "as"). Since this comparison is maintained throughout the poem, it is also an extended metaphor. The line also contains imagery (tactile and visual) as it creates a picture of something light and soft.
(e) What does the phrase "and then moves on" suggest about the nature of fog?
The phrase suggests that fog is temporary and impermanent. It does not stay forever. Just as a cat comes, sits for a while, and then walks away, fog too arrives, lingers, and then lifts. The phrase also conveys the indifference and independence of nature — the fog does not need any reason to leave; it simply moves on.
The poem "Fog" has no rhyme scheme — it is written in free verse. There is no fixed metre or pattern of end rhymes. This is a deliberate choice by Sandburg. Free verse mirrors the movement of fog itself: fog does not move in a predictable or patterned way; it drifts and settles and lifts according to atmospheric conditions. By using free verse, the poet gives the poem the same unpredictability and quiet freedom that characterises fog. The absence of rhyme also prevents any sing-song quality that would break the poem's mood of quiet observation.
Impermanence — the quality of not lasting forever — is central to the poem. The fog arrives (line 1), settles for a while (lines 3–5), and then moves on (line 6). This is the complete life cycle of the fog in the poem, and it mirrors the broader truth that all natural phenomena are temporary. The fog covers an entire harbour and city, yet it does not stay. It does not become part of the city; it simply passes through. The final line — "and then moves on" — is the clearest expression of this theme. It reminds readers that everything in nature is transient.
Similarities:
- Both move silently and without announcement.
- Both arrive without being noticed until they are already there.
- Both pause and observe before moving on.
- Both are independent — they follow their own rhythms, not human schedules.
- Both are mysterious and somewhat unpredictable in their movements.
- Both depart quietly, leaving no trace of their passing.
Differences:
- A cat is a living creature; fog is a meteorological phenomenon.
- A cat has a solid, visible body; fog is made of water droplets and is semi-transparent.
- A cat can be touched and heard; fog cannot be touched in the usual sense and is entirely silent.
The brevity of the poem is absolutely its greatest strength. Sandburg was a master Imagist, and the Imagist principle is that a single perfect image, captured concisely, is more powerful than a long, detailed description. The fog's movement is a fleeting experience — blink and you might miss it. A long poem would contradict that quality; it would suggest the fog is dramatic, important, and worthy of extended attention. Instead, six lines say: fog comes, sits, and goes. That is all. The brevity of the poem matches the brevity of the fog's visit. The form and content are perfectly aligned.
The poem presents a peaceful, non-confrontational relationship between nature and the city. The fog — a natural force — quietly overlays both harbour and city without destroying or disturbing them. There is no conflict. The fog does not respect the boundaries of human civilisation; it simply passes over and through them. Yet the city is not threatened. When the fog moves on, the city presumably resumes its normal life. This suggests that nature and human civilisation can coexist — nature visits the city on its own terms, and the city endures. The poem's calm tone reinforces this quiet coexistence.
Several life lessons emerge from this short poem:
- Nothing is permanent: The fog comes and moves on. Whatever comes in life — problems, joys, difficulties — will also pass.
- Silence can be powerful: The fog achieves enormous coverage (harbour and city) in complete silence. One does not need noise or drama to be effective.
- Observe the world quietly: The poem encourages us to notice the small, quiet events in nature — the arrival of fog — that we might otherwise overlook in the rush of city life.
- Simplicity is beautiful: The poem itself is a lesson in doing more with less. Six lines, one image, one truth.

The central metaphor in "Fog" is the comparison of fog to a cat. This comparison — known as an extended metaphor — runs through all six lines of the poem. The fog "comes on little cat feet" (arrival), "sits looking over harbour and city on silent haunches" (staying), and "moves on" (departure). This metaphor is highly effective because a cat's most defining qualities — silence, stealth, independence, and unpredictable movement — are exactly the qualities that characterise fog. The metaphor makes the abstract phenomenon of fog vivid, concrete, and relatable. It also personifies the fog, giving it a sense of quiet intelligence and self-direction.
"Little cat feet" refers to the soft, small, padded paws of a cat that make no noise as it walks. The phrase tells us several things about the fog: (1) it arrives silently — without sound or warning; (2) it moves slowly and gently — not rushing in like a storm; (3) its presence is unexpected — like a cat that appears before you realise it has entered the room; (4) it is light and soft — not heavy or oppressive. The phrase is the poem's most celebrated image and captures the essential character of fog with extraordinary economy.
1. Extended Metaphor: The entire poem compares fog to a cat. "Little cat feet," "sits," "haunches," and "moves on" all describe cat behaviour, but they are applied to the fog. This sustained comparison is called an extended metaphor.
2. Personification: The fog is given human and animal-like qualities. It "sits looking" over the harbour and city — as if it has eyes, consciousness, and the ability to observe. This personification makes the fog seem alive, aware, and present.
Yes, the poem does celebrate nature's quiet power. The fog, a natural phenomenon, covers an entire city and harbour — yet it does so in complete silence, on "little cat feet." It does not need to announce itself or cause destruction to demonstrate its power. The use of the words "sitting" and "looking" over harbour and city shows that the fog is in a position of dominance — it overlooks everything from above, like a ruler surveying a kingdom. Yet this dominance is achieved without noise or violence. Even its departure ("and then moves on") is quiet. The poem shows that nature's power does not require drama; it is most powerful precisely when it is quietest.
There is no rhyme scheme in "Fog" because the poem is written in free verse. Sandburg chose free verse deliberately — just as fog drifts freely without following a pattern, the poem too drifts freely without a fixed rhyme or metre. A regular rhyme scheme would give the poem a musical, predictable quality that would feel out of place for a phenomenon as free and unstructured as fog. Free verse also allows the poem to be as brief as it needs to be — six lines — without having to pad or extend the content to fit a rhyme pattern. The effect is one of natural, unforced simplicity.
