Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins and put a burning candle inside. It looks as if there were a person looking out of the pumpkin! These lige children paint their faces to look like monsters. Then they carry boxes or bags from house to house. Every time they come to a new house, they say,Trick or treat! Money or eat! The grown-ups put treat-money or candy in their bags.
