The picture shows how the color black is used as a sign of death. This picture shows when Tessie Hutchinson chose the dreaded black dotted paper and how it says in the text "the children already had stones in their hands" and "Mrs. Delacroix selected a stone so large she had to pick it up with both hands".
"the black spot Mr.summers had made the night before with the heavy pencil in the coal-company office". The imagery in this instance being the heavy pencil.
The figurative language in this image is slang when in the text it states... "so it could begin at ten o'clock in the morning and still be through in time to allow the villagers to get home for noon dinner". Noon dinner was a term used exclusively in the South and not the North.
The tone of the story remains the same by the author, we see a community kill one of their own members and they act as if its just another Sunday evening . This is also shown when the audience sees the change from the normality of the community to nightmarish horror all with the slightest change of tone from the author.
The theme of "The Lottery" is about traditions and customs and how vital they can be to a society such as the anonymous town mentioned in the story. whats so important about the tradition in the story is that it seems to be everlasting no one knows when it started or if it will end. The lack of history is what makes the tradition so meaningful to them.
