We are quite familiar with tightening of doors’, windows
and drawers during rainy season. In the winter, the same doors,
windows and drawers become loosened. Sometimes, unsightly
cracks make their appearance even on the costly furniture.
There is every reason that we feel disgusted and disappointed
with this undesirable behaviour of wood which we purchase in
exchange of our hard-earned money and we expect that the
furniture made out of it would behave well. We make carpenters
responsible for these too. in fact, we should blame
neither carpenters nor wood. This is due to shrinkage and
swelling which are inherent properties of wood. The following
the cause of shrinkage and swelling
and also suggests the remedial measures for their minimization.
Lost in the oblivion is the memory
the days, when I was born in the lap of my country.
I know not the history ofmy birth,
Find ye out, for my countrymen, for all ITm worth.
The development program of the Forest Research
Institute aims, among other things, to establish an organization for research in the field of forest management, a
the task which has up to the present day been performed by the
office of the Silviculturalist in the Development Circle.
A United Nations Special Fund Project has been initiated by
the Pakistan Government as an integrated part of the development scheme.
Introduction
Most of the tropical hardwoods contain silicae
and other minerals more or less. Sawing of these timber
species is sometimes very difficult, since the cutting edges
of the saw teeth blunts quickly. Due to this sawing difficulty some of the timber species of the forest remain unutilised and are never brought to profitable use. Sometimes the
rate of dulling of the teeth is so high that time and labour
consumed in preparation and sharpening of the blades turn
into sheet waste. So, attempts to coat the cutting edges
of the saw teeth with some wear-resistance metal is justified*
