And for my next trick.

This cygnet walks down the vertical wall to explore the lower pond.
This little river wanders across flower filled meadows and has a pool where Lord Byron used to swim.

Those who lived here in ancient times called their river the Cam. Later, and a little downstream, people built a bridge and understandably it became known as Cambridge.

Clever people came to live here to pursue their spiritual and intellectual activities. Brilliant minds attracted more of their own kind and over centuries they became famous across the world.
Their discoveries have affected all our daily lives. They split the atom and helped to develop computers.
Most of their work has given us a richer, better life. But if we misuse their work it may not always be so.

But the little river will continue to wend its way gently to the sea.
