One of the best of these is to immerse the timber in water as soon as it is cut down, and after it has remained about a fortnight in water, but not more, to take it out, and dry it in an airy situation.
Seasoning of timber is the process by which moisture content in the timber is reduced to required level. By reducing moisture content, the strength, elasticity and durability properties are developed. A well-seasoned timber has 15% moisture content in it.

Summing up, Defects in timber can occur at various stages, principally during the growing period, during the seasoning and conversion process, and also due to irregularities in the character of grains.
Defects affect the quality, reduce the strength, compromise the quantity of useful wood, spoil the appearance, and call its decay faster than usual.
The process of removing moisture from timber before it is used and put into service by drying in air. Two main methods of seasoning are air-seasoning (natural seasoning) and kiln-seasoning (artificial seasoning).
