The yellow fog that rubs its back upon the window-panes
The yellow smoke that rubs its muzzle on the window-panes
Licked its tongue into the corners of the evening
Lingered upon the pools that stand in drains,
Let fall upon its back the soot that falls from chimneys,
Slipped by the terrace, made a sudden leap,
And seeing that it was a soft October night
Curled once about the house, and fell asleep.
This stanza goes on to further describe the setting of the street that is within the previous stanzas. The metaphoric relation of the streets to that having a "back", "muzzle", and a "tongue" leaves the reader associating the street with a sort of primitive animal. It goes as far as to give the street actions of "leaping", "curling", and "fall on its back". These relations don't just describe any animal, they closely resemble the actions of the common house cat. Eliot uses powerful imagery to project a visual aid of the poem's setting. The "soft october night" also compliments the setting, depicting an early autumn night.
