     For years children in the industrial areas of Europe and America seldom left their smoky cities to see the

beauties of the countryside. Not that the woods and fields were always far away, but they were too far from

the city to permit people to make a round trip between morning and nightfall. What's more, factory workers

did not have enoug money to send their children on country holidays away from home.

     In 1907 a young German schoolmaster had an idea which changed this state of affairs. He decided to turn

his little schoolhouse into a domitory for the summer holidays. Anyone who bmught his sleeping bag and

cooking equipment along could stay there for a very smaU amount of money. The idea was a success. A few

years later the schoolhouse was far too small to hold so many young people who wanted to stay there. So, a

dormitory was set up in an old caste nearby. This was the first Youth Hostel.

     Today young students and workers of every country can meet in the hostels and get to know each other.

Some spend a week or more in the same hostel, seeing the surrounding sights and meeting the people of the

area. Other youths go on foot or by bicycle from place to place, spending a night or two in one hostel, then

going to the next.

     Sometimes an infomal program will be organized after the meal, with dances, songs, or short talks followed

by a question period. One can _____ about other places, just by meeting people who come from these places.

For this reason, a few weeks spent "hostelling" can be just as useful a part of one's education as classes in

school.
