Air drying is an important mode of seasoning timber in
Bangladesh where sawnjill owners and lumber dealers can hardly
afford to possess modern dry kilns. Due to lack of adequate
knowledge and absence of proper drying schedule, the method is
not being practised effectively to get the best result. It is,
therefore, considered ‘partinent to study the air drying characteristics
of some of the important wood species of Bangladesh.

The establishment of efficient drying schedules for various
species is dependent upon the rate at which a given species loses
moisture. This is, also, affected by the drying condition existing
in a particular region at any given time of the year. The present
paper deals with the rate of moisture loss and air drying time of
10 indigenous wood species of Bangladesh under two conditions of
exposure.
