He was dying of thirst when he came upon a pitcher. The pitcher had once been full but now only some water remained at the bottom. Crow looked about. He saw that the ground was covered with several pebbles of all shapes and sizes on the grass.
An idea came to him. He dropped one pebbles into the pitcher.
The water rose a few centimeters. Crow dropped many more pebbles into the pitcher. The water rose higher. Then,he poked his beak into the pitcher and started to drink. At last,Crow was no longer thirsty.
