with a little dispassionate thinking one is
likely to conclude that possibly no other natural resource
of the world has been so shabbily treated by the human beings
as the forests had been from the pre-historic days till
to-day, both collectively and individually. The original
inhabitants of the earth lived mostly as denizens of the
forests depended on forests and forest products for their
food and shelter. But they gradually cleared the forests
to their advantage to live a better life away from the
forests. New society has grown, new civilization built up,
new kingdom established, new economy flourished at the cost
of and on destruction of forests. But hardly people have
realised its importance or care to look back with any sense
of gratitude to this important natural resource of the world,
is so vital even in the modern civilized society. Forest and
forest products have been playing important role to the
nations in support of agriculture , in the growth of industry, giving protection in natural clamities and making provision for its growing population in earning livelihood and
thereby helping economic development of nations in earning
or saving foreign exchange. Forest products are again in
the service of any individual from T cradle to coffin1 but
very often an individual offers his gratitude by using his
injudicious brutal axe in cutting a mighty tree, which might
have grown for over hundred years serving his fellow men for
generations, and even without caring to replace this gift of
nature by planting atleast a similar one is a suitable pice.


One of the chief disadvantages of wood in use
is its inability to retain its shape with the change in
the moisture content. It shrinks and swells as water is
desorbed or adsorbed in the cell wall of the wood fibre
which is composed primarily of cellulose ‘mnicrofibrils.
The hydroxyl groups—of—the e. e ll.ulose c.hain-exhibi^t—strong…-
affinity for water molecules* The hygroscopisity of wood
