The clever, clever Crow

Once upon a time, there was a very thirsty crow. He went everywhere looking for water and suddenly came upon a jar with a little water at the bottom.

But the crow could not reach the water. However, the clever crow had a wonderful idea.
He flew back and forth with stones in his beak and dropped them into the jar. And as the stones filled little by little the water rose to the top. The crow happily drank his fill and flew away.
