Crow,s cleverness

There was a huge banyan tree in a jungle.A crow and his wife used to live on it. It was unfortunate that whenever they had children,a black snake that used to live in a hole in it,would come out and eat them up.They were very unhappy.so,they went and told this tragic story to their friend,the jackal,living close by and asked him for advice as to how to get freedom from trouble.
** The jackal said," Now,you dont worry about this.He will have to be killed by a trick.This can do the work that even arms and ammunitions cannot do,in exactly the same manner that stork who was so greedy,lost his life.**
