Which lines from "mending wall" indicate that the neighbor is willing to participate in mending the wall?

 “Bringing a stone grasped firmly by the top in each hand, like an old-stoned savage armed”  This indicates that people were willing to repair the wall. He believed that good fences made good neighbors and thus set about mending the wall. This is the line I believe indicates the neighbor is willing. Hope that helps!
