BR-15:Why the sea is salty.

Long time ago, the sea was not salty like it is today. Once, it tasted sweet. So where did the salt come from? Well, it all began with a magic millstone. The thief hid the millstone under his cloak. He ran all the way to the sea. He leaped into a boat and sailed away. 

 I say this story by here. What will happen after this? I recommended this book.

I had never thought that Why the sea is salty? And I was surprised that the sea was not salty like it is today. Why the sea is salty? I think that it is interesting when I think each other. How about you?
