What metaphors are used in Cane by Jean Toomer?

In Chapter 23, Her Lips, Toomer affords the reader a distinctive and versatile perspective on the world around him. While he uses natural imagery liberally throughout Cane, this poem relies on man-made technology to make its point. The woman in the poem clearly has power and influence over the narrator. To continue the metaphor, her touch and her kiss are electric. His attraction for her is something hot and glowing against the dreary backdrop of the foggy city at night. Her lips, as copper wire, conduct her energy to him.
