State two purposes of seasoning timber?

1. Remove excess moisture: One of the main reasons for seasoning timber is to reduce the moisture content. Wood is hygroscopic in nature, meaning it absorbs and releases moisture from the surrounding atmosphere. Seasoning helps in reducing the moisture content, making the timber more dimensionally stable and less prone to warping, shrinking, and swelling.

2. Enhance durability: Another purpose of seasoning is to make timber more durable and resistant to decay and insect infestation. Excess moisture provides a favorable environment for the growth of fungi and insects. Seasoning helps in reducing moisture content, making it less vulnerable to decay-causing organisms and wood-boring insects.
