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.

Introduction :
■ Watershed management is concerned with the hydrologic
effects of land use and vegetative management. Water is considered
a product of the land which, within limits set by nature, can be
managed just as other renewable natural resources. In watershed
management the emphasis is not on harnessing water in streams but
on managing on the land itself, before it enters the streams or
.ground water basins. Watershed management may be called as handmaid of Engineering Water Development. This is most evident where
engineering structures erected for better water supply and regulations of stream discharge are threatened by erosion and premature
sedimentation, where the remedy lies in the introductionof conservative land use practices and suitable vegetation patterns combatable with the water producing function 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.

Abstract:

Pakistan consists of two regions, viz., East and West
Pakistan, separated by nearly 1,000 miles of Indian territory,
climatic conditions, the soil and forest types of these two regions
are varied. On the national basis, less than ten per cent of the
total land area is classified as forest and range land. In-East
Pakistan, however, 17.3 per cent of the land area is forest land of
which approximately ten per cent is under scientific management and
the remaining 7.3 per cent is in the category of unclassed state
forests where shifting cultivation by the tribal people is practised.
Less than one third 01″ the forest area in West Pakistan is regarded
as productive forest hind and the balance is range land,

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

Introduction :
This paper describes the paper making properties of
various types of paper prepared from the mixture of 8(eight) minor
hardwood species, viz, Itchri (Anogeissus acuminata), Amra
(Spondias pinnata) , Barta (Artocarpus lakoocha), Champhata
(Sapium baccatum) , Gutgutia (Walsura robusta), Chakua koroi
(Albizzia chinensis) , Kuramara (Pithecolobium angulatum) r -Jagga
dumur (Ficus glomerata). These minor hardwoods are scattered all
over Chittagong and Chittagong Hill Tract areas. In an earlier
work conducted in this Institute (1) chemical and semichemical
pulping studies of these mixed species were performed and the
effects of various pulping variables on the resultant pulps were
determined.
