Introduction This report is the result of a study
tour of a fair cross section of wood processing industries of
the Midwestern and Southern United States. The States visited
orc, Illinois, Missouri,
Tennessee, Arkansas and Wisconsin,


Trees are attacked by a number of fungi. Some live on the foliage, some are attached to the living shoots and others to the wood. Some fungi are parasites feeding on living tissues, some are saprophytes feeding on
dead parts of the trees.


The study tour on forestry research was sposored by
FAO in connection with the UNDE assistance to Forest Research
Institute, Chittagong, (Project Pak 30). The object of the
study tour was to enable the counterpart traveller to obtain
up-to-date knowledge on the methods used in forestry research
which may be applicable to silvicultural research in East
Pakistan. Necessary contacts, with the forestry research orgaForestry Department of FAO.


Pulping experiments have been conducted on Ekra
(Erianthus Ravennao), Khagra (Saccharur Spontaneum) and Nel
(Phragmites Karka) – three gross species of Sylhct District
of East Pakistan for the manufacture of writing, printing,
wrapping and special types of papers. The grasses were cooked
individually and in various percentages of mixtures’. Effect of
the presence and absence of’ leaves during cooking have also
been studied.


A study on the.succesion of species in the clear felled
areas of tidal forests of the Sunderbans revealed that the
clear felled area was filled up by Gewa and Sundri within 2-3
years of such felling. Gewa was found to be the first coloniser
followed by Sundri. On.avera^e, the percentages of occurance
of Gewa & Sundri had been found-to be 55 & 27 respectively.
Sundri followed Gewa in height growth in first 10 years
formed a co-dominent associate while the dominating species
Gewa attained the average height of 15′ in 10 years’ time with
a b.h diameter of 3” •
