Stop in for a cup of coffee

There are some 4" diameter roots coming in. They probably were looking for water since the basement has a dirt floor and it is always damp down there because way back it had a artesian spring in it. I was going to put a dehumidifier down there but started thinking that if it was dried out after 200 years will the beams (tree trunks) buckle so I am leaving it that way. Amazing all the wood is in good shape.
