In a hot summer day, a crow became very thirsty. It was desperately searching for water but in vain. The crow did not lose heart. It kept on searching water. At last it found a jar at a little distance. Then it flew there and found a little water at the bottom of the jar. But the layer of the water was beyond the reach of the crow. Suddenly, he saw some pebbles around the jar. Thinking for a while, the thirsty crow started to drop the pebbles into the jar one by one. After some time, the layer of the water coming up. When the water level came within its reach, it successfully drank water and flew away with a fully content mind.
