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.
The average moisture content of modern softwood timbers in dry buildings is generally in the range of 12â15%, and heating systems may reduce this to a far lower level. There is, therefore, no prospect of a dry rot infestation developing in a building that has been properly designed, constructed, and maintained.
