The part of Bengal bounded by the river system
Brahmaputra-Jamuna-Ganges to its North is generally known as
, North Bengal. The portion of North Bengal which came to Pakistan
and ’’Khiar”. ’Poli’
after independence of the country inherited small’areas of
natural forests. The scope of this papfer is limited to the
Pakistan portion of the North Bengal. Of the five Civil
Districts of North-Bengal namely, Rajshahi, Rangpur, Dinaj pur,
Pabna and Bogra, there is no forest at all in Pabna and Bogra.
About 85.5%: of the forest areas are situated at Dinajpur
district, 11,6 at Rangpur District. but* contiguous to the
, r ’ ‘• ■ ■ Dina.jpur forests and 2.5% at Rajshahi. The.forests of the
present Rajshahi district were also the part of undivided
Dinajpur district but became intercepted due to partition of
Dinajpur district-at the time of Independence.

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
— is due to–these–water loving hydroxyl groups. In the swollen
state water is adsorbed to the easily ■ accessible–hydroxyl- — –
groups of the less^ordered..amorphous–region^–With-the loss
of water, on.Jurying 3 surface tension forces pull the adjacent
cej, ] nInsebchains together causing shrinkage of the fibres
equal to the volume of water removed.

Where there is sincere desire and a felt need for
improvement, there must be emphasis on research. In U.S.S.R.
there exists such an emphasis visible everywhere. Large number of research Scientists are engaged in productive research activities in many well-equipped research Institutes dealing with problems of logging and wood-based industries.Adequate funds are provided for annual budget of these institutes. They are provided with pilot plants and experimental
farms where they can try and test efficiencies of various
equipments and techniques designed and developed by them.

ELEPHANT
(Elephas maximus)
The majestic ’elephant which is associated with the
Indo-Pakistan Sub-continent from time immemorial with the
spendour of her princely pageantry is one of the most prized
animal of our forests. Along with the famed Royal Bengal Tigers,
this animal also can rightly claim to be one of the most fabulous
animal of this, part of the country. But unlike the Royal Bengal
Tiger which found its way from northern-cooler country, the
fossil remains prove beyond doubt that the elephants can claim
this Sub-continent as their ancestral home for long 5,00,000
years. Fossil remains of seven species of true elephants and
eight species of mastodons have been discovered in the IndoPakistan Sub-continent. They used to roam around the sub-continent
in the prehistoric days,. One by one they faced extinction and
to-day we are left with .only one species in the whole of the
Sub-continent. East Pakistan having possessed a share of this,
unique species of the;olden days can rightly be proud of.

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.
