Hugh Troy, a well-known artist, was a very interesting and clever person who spent most of his life playing tricks for the joy of it.

One winter in the 1920s, while a student at Cornell University in Ithaca, New York, Troy got hold of a very old and ugly wastebasket with a real rhinoceros (犀牛) foot as its base. He filled it with metal weights and tied 30 feet of clothes\|line to either side. Late one night he and a friend carried it out onto campus (校园), pulling the lines straight between them. Every few feet they would lower it into the snow, their own footprints so far away as to raise no suspicions (怀疑).

The next morning someone noticed the prints and invited learned professors to come and have a look. Excitedly, they followed the rhinoceros tracks. Then they were led onto the ice covering Beeb Lake, which connected (连接) to where the school got its drinking water. There the tracks ended in a huge (very large ) hole.

It was said that half the population of Cornell stopped drinking tap water. Those who continued to drink it insisted that it tasted like rhinoceros.

Let's pretend we're sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is heavy. It's interesting to watch the many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards (葡萄园) on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world.

Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei.

The someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren (美女) who has lured many sailors to their deaths.

The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her forget to steer, and the current of river hurls their boats on the rocks and dashes them to pieces.

Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.
