Yep. You and Duane Bozarth both called the sloping/humidity issue with
the basement. ...Why does the earth slope towards old houses? Is that 100 years

Yes, plus there's a tendency for the yard elevation to go up owing to
the many years of accumulated thatch, etc., that builds up and
eventually ends up as additional humus/soil. Where I am that process
was accelerated drastically in the 30s w/ the blowing dirt of the Dust
Bowl which is a significant contributor to my problem as I mentioned
before...
