Oklahoma is one of 20 states where Census County Divisions (CCDs) are used for statistical tracking of subdivisions within each county. The City of Madill is located within North Marshall Division of Marshall County.
The shape of timber changes due to variations in moisture content (MC). In Scandinavia, the producers of timber normally dry timber to a moisture content of 18% MC. However, after the studs are built into the wall structure, for example, they may become distorted as a result of further drying in the structure.
Because dry rot is not able to sustain itself on timber that is below 20% moisture content the primary control measure for any dry rot outbreak is to identify the cause of excessive moisture, eliminate it and allow wetted areas to dry out rapidly in well ventilated conditions.
