    Today, roller-skating is easy and fun. But a long time ago,it wasn't easy at all. Before 1750, no one had

any ideas of roller-skating. That changed because of a man named Joseph Merlin. He liked to make things

and play the violin in his free time. Joseph Merlin was a man of ideas and dreams. People called him a

dreamer.

    One day he was invited to a party. He was pleased and a little excited. As the day of the party came near,

Merlin began to think how to make an amazing entrance at the party. He had an idea. He thought everyone

at the party would show much interest if he could skate into the room.

     Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe.

These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party

on wheels while playing the violin.

     On the night of the party Merlin rolled into the room playing his violin. Everyone was very surprised to

see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on.

Suddenly, he ran into a huge minor that was hanging on the wall. The mirror fell down, breaking into pieces.

Merlin's idea was so good that nobody forget his special entrance for a long time. But could he find out a

way to stop his roller skates?
