It was a hot summer day. A crow became very thirsty. He flew here and there in search of water. But there was no water to drink.
The crow sat upon a tree to take rest. Suddenly he saw a pitcher in front of a house. He flew to it with great hope. He sat upon the pitcher. But there was a little water at the bottom of the pitcher. The water was out of (beyond) his reach. He became sad and began to think what to do. At last he hit upon a plan. (Suddenly a clever plan came to his mind.) There were some pebbles nearby. He bought them in his back and dropped them into the jar one by one. Gradually the water level rose. The water soon reach the top. Then the crow drank the water and quenched his thirst and flew away with a happy mood.
Moral: Where there is a will, there is a way.
Necessity is the mother of invention.
