I am still reading my new book but have been thinking you may find this interesting.
I love some old out of circulation books.
This is" The Diary of a Plain Dirt Gardener"
This was written by Harry R. O'Brien in 1933.
Harry was published in Better Homes and Gardens,
and The Country Gentleman Magazines. He also taught at Ohio State University.
I collected post war magazines and others ,
this is a article from 1935 Better Homes and Garden about Gardeners that write books.
