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.
Other sources of moisture may also include: 1  water leakage through the building envelope. 2  damp ground conditions under suspended timber floors. 3  retained construction moisture, i.e. moisture retained in building materials such as timber framing, concrete floors and plaster, after installation. 4  plumbing leaks.
