The Old black box is an evidence that a horrible tradition has been followed since a long time ago. It can also represent death.
We can find imagery as the author describes Bill Jr.. ''His face red and his feat overlarge"(The Lottery). By describing him we know that he is in his teen years.
We can see personification in ''The Lottery"" when the feeling of freedom sat uneasily on the children as they knew someone was going to die they fulled their pockets with stones. Giving freedom the human motion of sitting makes it a personification.
The tone from ''The Lottery" is neutral. As the story advances and the real purpose of lottery is shown while people prepare to stone to death a person the author maintains the neutral tone making a connection between the theme and tone.
The theme of "The Lottery" is that people can blindly follow traditions, just because of simply being a tradition doesn't make it right. Humans can become extremely cruel because of what they choose to believe and follow.
Imagery can be seen in the last parts of the story as the people prepare to kill. As Mrs Delacroix prepares to kill , "Mrs. Delacroix selected a stone so large she had to pick it with both hands", this can be seen as her showing her hatred for Tessie.
