1930 US Census Enumeration District 78-31 Boundary Description

Please help me.

I am looking for the 1930 US Census Enumeration District 78-31 Boundary Description for Warren Township, Trumbull County, Ohio [example:  "Bounded by (N) Street Name; (E) Street Name..."].

I have the Boundary Description for 1940 US Census Enumeration District 78-50, but the above information would fill in the blanks of the genealogy spreadsheet I am compiling for myself.

Thank you.
