In this picture, Mr. Summers is resting his hand "carelessly on the black box" (lines 103). This is where all of the villagers had began to gather as Mr. Summers waited for everyone to assemble. Once everyone was assembled, the villagers would begin to pick a card out of the black box in which would determine their fate. The black box represents death.
TONE AND THEME
In this picture, it was "clear and sunny, with the fresh warmth of a full summer day..." (lines 1-3). You can see that there isn't a single cloud in the sky and the sun is very prominent. Also you can see two boys picking out the "smoothest and roundest of stones.." (lines 18-20). There are two piles on the ground, one with the good stones and another with the less wanted stones.
In the picture, it is foreshadowing the upcoming events. "Bobby Martin had already stuffed his pockets full of stones.." lines 15-18). This action from Bobby Martin foreshadows the event later on when Tessie Hutchinson would get stoned.
In the picture, it shows the tone in which everything seems normal. Tessie gets picked for the lottery this year. Most would assume she's shocked with contentment however, for the theme, not everything is what it seems. If you look closely at the picture, the civilians have stones in their hands ready to throw at Tessie.
