Would you please give me the synonymous expression or periphrasis of the idiom 'to grow hair on a cross-cut saw'? May be you happen to know the etymology?
I guess that it refers to the extremely fertile soil like in "Mississippi delta bottom land will, for the most part, grow hair on a cross-cut saw." or "The land was rich, black, and fertile. Papa said it would grow hair on a crosscut saw."
Thank you all in advance!
