In John Steinbeck's "Cannery Row," the imagery of the sun rising signifies a shift from the coldness of night to the warmth of day. The sun's arrival is depicted as an active force, shaking off the chill as one might shake a rug, illustrating the freshness and potential of a new day. This metaphor evokes a sense of rejuvenation and invites the reader to appreciate the simple beauty of nature's cycles.

The passage highlights the contrast between night and day, symbolizing hope and renewal. It suggests that with the dawn comes a chance for new experiences and opportunities, emphasizing the interconnectedness of the environment and the human spirit. Through this vivid imagery, Steinbeck captures the essence of life's rhythms and the assurance that each day brings the possibility of change.
