II. From the History of Sandwich


The Earl of Sandwich lived long ago in England.
He was a fanatic about playing cards. He didn’t even want to stop playing long
enough to eat a meal. So he invented a quick meal. He put some meat between two
slices of bread. Then he could hold his meal in one hand and play cards with
the other.
     Sandwiches were great favourites in Victorian England. It was the tradition to take afternoon tea at about 5 o’clock, and many rich families ate sandwiches at that time. Cucumber sandwiches were very popular. The servants always cut the crusts off the bread,
so the sandwiches were very small and delicate.
     Sandwiches are less elegant now and often much bigger. The American strip character Dagwood Bumstead is famous for his “Dagwood” sandwiches which have up to 10 slices of bread packed with different fillings all one on top of the other.
     The English eat millions of sandwiches every day. They are a typical “snack” meal because they are easy and quick to prepare. You can buy sandwiches if you don’t want to make them yourself. There are thousands of sandwich bars and cafes and even some
restaurants that sell them.
