It is very hot and dry in the desert. The sun is shining all day. A crow is very thirsty. Suddenly he sees a jar with a little water. But the mouth of the jar is too small and his beak can't reach the water. He thinks hard. Later he has a good idea. He collects little stones and drops them into the jar one by one. The water in the jar rises at last. He is able to drink the water. How clever he is!
