My inquiry is about an old story that a dear friend told me.  She was born in the 30s and, I believe must have heard the story when she was young.

She thinks it was in a book of children’s stories.  It is about Buster Hard Rocks and Tilly Fields.  The moral of the story is how difficult it is to grow and prosper crops or other things you are growing when all you have in your field are hard rocks.  But if your field is easily tilled, then you can grow crops.  Then similarly in your life, the condition of your heart and mind can be difficult to cultivate if you are hard and unwilling to listen and be persuaded.

I would love to find a copy of a book with this story in it.
