In G. K. Chesterton's Father Brown short story, The Blast of the Book, he makes two references to a story (presumably allegoric) about a woman who collected valueless things. The references are not explained and from the context it seems that the reader is assumed to be familiar with this story.
The relevant quotes are:
I've often had to wait in your office, till you turned up; and of course I passed the time of day with poor Berridge. He was rather a card. I remember once he said he would like to collect valueless things, as collectors did the silly things they thought valuable. You know the old story about the woman who collected valueless things.
He has nonsense notions of all sorts. About collecting useless things, for instance. Don't you know the story of the woman who bought the two most useless things: an old doctor's brass-plate and a wooden leg?
There seems to be some point being made with the reference to the old story, but without knowing that context it's hard to know what the point is. What is the original story about the woman?
