Shepherd’s steamers. The river at Gumbala is some 200 yards broad, 
and always contains a plentiful supply of fresh water, while small boats 
of 5 tons burden can reach it from the sea. It is for this reason, as also 
from the fact that the place is fairly healthy and open, that it has 
been chosen as a suitable site for a pulp-mill. 
(6) Outturn. 
The outturn is based on the eight sample plots taken in different parts 
of the area. The work was carried out by Mr. Miller, the Divisional 
Forest Officer, his Assistant Mr. Kotwal, and the writer of this report, 
when the latter was on tour in that District. Owing to the bamboo 
growth being heavy on the more level ground and lighter on the slopes, 
it has been considered necessary, for greater accuracy, to divide the forest 
into two quality areas. 
The total area of bamboo-yielding forest is computed at 68,723 acres, 
the figure having been arrived at by the use of a planimeter. Of this, 
38,643 acres are first class and 30,080 acres are second class bamboo forests. 
Referring to Appendix IV, sample plots Nos. 1 to 6, we get 10,149 lbs. per 
acre as the average outturn of dry internodes in first class areas, and from 
sample plots Nos. 7 and 8, 1,975 lbs. per acre in the second class areas. 
The total gross yield for the whole area, taking into consideration the 
areas of the two quality classes and their yield per acre, therefore, works 
out to 451,595,807 lbs. or 201,605 tons. The question as to a suitable 
rotation on which to cut bamboos has been already discussed in Part II, 
and has been fixed at 5 years, so that the total sustained yield of dry 
internodes works out to 40,321 tons per annum. As it will probably 
be found possible to treat the nodes together with the internodes the an¬ 
nual yield may be raised by 15 per cent. 
(7) Lines of export. 
There are two methods by which the bamboos can be exported (1) 
by floating down the Gangavalli river and (2) by carting along the 
Yellapur-Karwar road which runs down the entire length of the valley 
close to the river. It would be necessary to drag the bamboos to the 
edge of the river or road, a maximum distance of three miles, but, 
generally speaking, not one-third of that distance, and afterwards either 
to float them in rafts down the river or cart them along the road.
