The symbol that I chose is the black box. Although this box is not the original one used for the first lottery in this story, it still symbolizes death in their town. The person who gets the slip in the box with the black dot scribbled on, is not the lucky winner, they're rather the unfortunate one who is given death.
Tone and Theme
Here, Mr. Summers is talking to Mr. Graves and the Martins just before the lottery takes place. I included this image because in the text, the author describes Mr. Summers in a "clean white shirt and blue jeans, with one hand resting carelessly on the black box, he seemed very proper and important".
This image includes Old Man Warner standing next to Mr. Adams having a conversation about the lottery itself. In the conversation, Old Man Warner lets a hyperbole slip. and thinks the "young folks" are fools for wanting to end the lottery tradition and adds that "there's always been a lottery", but really there hasn't. He is exaggerating when he says that.
The theme is simply tradition. The black box and the stones represent the inevitability of death which is a tradition in the small town of 300 people. Strange is the tone that goes along with this story; the character Tessie's cry for fairness and sympathy is ignored and even her family joins in the act of stoning her.
