how did the logan children get back at the bus driver

A Bus passes close to them and forcing them to jump in the slimy, muddy gully to avoid being hit. A furious Little Man tries to throw mud at the schoolbus from which the white children yell "Nigger!" and "Mud eater!" When Jeremy tries to join them walking to school, Stacey ignores him. Stacey decides to dig a ditch across the area that fills with gully water and makes it look as if the road washed out from the rain. I think it's a good plan. I too would be frustrated and tis plan didn't really hurt anyone plus it looked like an accident.
