Indian Forest Records. 
[Vol. IV. 
The figures in the above table show variations from between Rs. 3 to 
Rs. 12 and in the case of the Kaladan and Lemru catchment areas 
Rs. 22 in the cost of extraction of one ton of dry internodes, and this is as 
might be expected, considering the varying conditions met with in 
the various provinces. The average is about Rs. 9 per ton for dry 
internodes and this figure is well within the economic limit of working, 
which is about Rs. 15 per ton. 
A point which requires explanation is the relative cost of exploiting 
100 bamboos as compared with the cost of landing one ton of dry inter¬ 
nodes at the mill. Take, for instance, the Kanoth forests in Madras. It 
costs Rs. 23 to land 100 bamboos at the mill, while it only costs Rs. 9-10-6 
to land a ton of dry internodes from the forest to that place. The reason 
for this is the enormous size to which the bamboos grow in that locality 
and therefore relatively few bamboos are required to make a ton of the 
raw material. The case is exactly the reverse in the Thonze reserve of 
the Tharrawaddy Division, where 100 Cephalostachyum pergracile cost 
Rs. 2-8-0 only, but on account of their lightness it costs Rs. 7-6-0 to 
land a ton of dry internodes at the mill. 
It is here of interest to note the figures of cost arrived at by 
Sindall in his report. In paragraph 31, page 13, of the report he 
writes : “ Cost of bamboos for the manufacture of pulp, with 
bamboo costing Rs. 9-8-0 per ton, the value of the raw materials 
required for a ton of unbleached pulp works out at a reasonable figure.” 
From the above table of figures, which have been based on careful 
weighings of many stems, and on enquiries into the local conditions, the 
figure arrived at is generally lower than that quoted by Sindall; 
nevertheless, they correspond sufficiently closely to corrroborate that 
gentleman’s estimates. 
9. Outturn. 
The outturn from any given locality must necessarily depend on 
the size of the area from which bamboos can be exploited and the size 
and density of the crop. 
Valuation surveys in bamboo areas. —One of the most arduous portions 
of this enquiry has consisted in taking a very large number of sample 
plots and linear valuation surveys in the various areas which were in¬ 
spected. In making these valuation surveys, after the sample plot had 
been laid out on the ground, every clump was counted within the area 
and every stem counted in each clump. In many cases the number of
