The black box is a metaphor for tradition in this story. It shows tradition because every year they do the same thing with the exact same thing. Another metaphor is the color of the box black. In the story the color black is representing death as in real life at funerals when everyone wears black. Also how Mr. Summers works at a coal company and the slips of papers are also black.
