"May be,she won't be there" said Michael
" Yes,she will" said Jane. "She's always there"
Mary Poppins and the children were on the way to the Bird  Woman!Mary Poppins walked between Jane and Michael.She had a new hat on and looked into every shop window.Was the hat OK? Didn't the pink roses turn into daisies?
At last they came to St. Paul's Cathedral.It was Built a long time ago by a man with a bird's name-Sir Cristopher Wren.That was why so many birds and the Bird Woman lived near Sir Christopher Wren's Cathedral.
"There she is " cried Michael suddenly.
"She's saying it!She's saying it !" cried Jane
And she was saying it.
" Feed the birds,tuppence a bag!Feed the birds,tuppence a bag!Feed the birds, tuppence a bag! " she said it again and again in a high singing voice.
In her hands the Bird Woman had a lot of little bags full of dreadcrumbs.They were flying or walking or eating somethink Mary Poppins didn't like them.She always called them "sparrows ".But they were not sparrows,they were pigeons.There were grey pigeons like grandmother;and brown pigeons like uncles;and very grey-green , noisy pigeons like father.And the silly soft blue pigeons were like mother.That's what Jane and Michael thought about them.
They flew round and round the head of the bird woman,and when the children came up to her,they suddenly flew away and sat on the top of St. Paul's , laughing and looking down.
