A clever crow.

One summer day a crow got very thirsty. It searched for water here and there. Suddenly it saw a jar at a little distance. It flew down to the jar. There was a little water at the bottom of the jar. But it was too law for the crow to reach...........

The crow tried to upset the jar but failed. So he crow was in a fix what to do. Suddenly it saw some stones lying beside the jar.  

The crow was very clever. A plan came to its mind. It picked up stones and dropped one after another into the jar. Then the level of the water began to rise and at one stage, water came to its reach. The crow drank water to its heart content and left the place happily.
