The three were walled in now. And each one felt the grip of hands. And then the wall of men moved slowly off the platform.
– John Steinbeck
The Grapes of Wrath, Chapter 24. Here we witness the success of group effort and co-operation with everybody in Weedpatch playing their part to preempt trouble at the dance. Steinbeck uses to metaphor to describe how three troublemakers are confronted by a wall of men before they can incite a riot.
