What are some quotes with symbolistic imagery in them from Fahrenheit 451 toward the end of the book relating to social conformity?

In the book's final scene, the men gather around a fire for warmth and cooking, as human beings have done for thousands of years.  Though it is a significant departure from how fire is used earlier in the novel, fire is used here as a means of organizing the men and ensuring their survival.  The image of the men silently watching the ritual of the bacon cooking is a reflection of social conformity: people gathering to share a meal.
As Granger, Montag and the other men break camp and begin their hike north, the men fall back to allow Montag to take the lead.  The fact that they have tacitly chosen Montag to lead them is another symbol and an image of social conformity. The men are free to think and act independently, yet they choose to stay together and allow a single man to lead them.  As they walk on, Montag rehearses in his mind what words he will later say to these men who look to him for guidance.
