Much later, when Christianity spread throughout Ireland and October 31 was no longer the last day of the year, Halloween became a celebration mostly for children. "Ghosts" went from door to door asking for treats, or else a trick would be played on the owners of the house. When millions of Irish people immigrated to the United States in the 1840s the tradition came with them.
Today' school dances and neighborhood parties called "block parties" are popular among young and old alike. More and more adults celebrate Halloween. They dress up like historical or political figures and go to masquerade parties（化妝舞會）. In larger cities, costumed children and their parents gather at shopping malls early in the evening. Stores and businesses give parties with games and treats for the children.Teenagers enjoy costume dances at their schools and the more outrageous the costume the better!
Certain pranks（惡作劇）such as soaping car windows and tipping over garbage cans are expected. But partying and pranks are not the only things that Halloweeners enjoy doing. Some collect money to buy food and medicine for needy children around the world.
Symbols of Halloween
Halloween originated as a celebration connected with evil spirits. Witches flying on broomsticks with black cats, ghosts, goblins（小精靈）and skeletons have all evolved as symbols of Halloween. They are popular trick-or-treat costumes and decorations for greeting cards and windows. Black is one of the traditional Halloween colors, probably because Halloween festivals and traditions took place at night. In the weeks before October 31, Americans decorate windows of houses and schools with silhouettes（輪廓）of witches and black cats.
Pumpkins are also a symbol of Halloween. The pumpkin is an orange-colored squash, and orange has become the other traditional Halloween color. Carving pumpkins into jack- o'lanterns is a Halloween custom also dating back to Ireland. A legend grew up about a man named Jack who was so stingy（吝嗇的）that he was not allowed into heaven when he died, because he was a miser（吝嗇鬼）. He couldn't enter hell either because he had played jokes on the devil. As a result, Jack had to walk the earth with his lantern until Judgement Day（審判日）. The Irish people carved scary faces out of turnips（蕪菁根）, beets（甜菜根）or potatoes representing "Jack of the Lantern," or Jack-o'lantern. When the Irish brought their customs to the United States, they carved faces on pumpkins because in the autumn they were more plentiful than turnips. Today jack-o'-lanterns in the windows of a house on Halloween night let costumed children know that there are goodies（糖果）waiting if they knock and say "Trick or Treat!"

Dried Pumpkin Seeds
After carving your pumpkin, separate the pulp from the seeds. Rinse（沖洗）the seeds and spread them out to dry. The next day, add enough melted butter or margarine（人造黃油）to coat each seed. Spread the seeds onto a cookie sheet（甜酥餅乾）and bake for 20 minutes in a 300 degree oven for 20 minutes or until they are slightly brown.
