describe the imagery and mood at the beginning of chapter 6. where does it take place? how does the description of the snake and the bird foreshadow what will come?

THe mood is quiet almost serene except for the underlying darkness of the situation. Note how the sun has gone down,

"The deep green pool of the Salinas River was still in the late afternoon. Already the sun had left the valley to go climbing up the slopes of the Gabilan Mountains..."

George is at their emergency rendezvous. The bird eats the snake, part of the natural order of things. It foreshadows what should have been the natural order of George and Lennie's lives. THis ending was somehow overdue.
