[Vol. IV. 
The present method by which bamboos are extracted, is to make rafts 
of three sections, each containing 300 Kyathaung or 600 Tinwa bam¬ 
boos ; these are floated down the upper reaches in charge of one man. 
As the stream widens out, the rafts are increased in size and on reaching 
the Myitmaka or Hlaing river, several sections are tied side by side and 
rafted down in lots of 6,000 to 7,000 to Rangoon. 
(8) Cost of cutting and extraction. 
The present rates for selected straight Tinwa bamboos, 20 feet in 
length, at Thonze on the railway line, is Rs. 3 to Rs. 5 per 100 stems and 
for Kyathaung Rs. 6 per 100 and for fine selected stems Rs. 8 per 100. 
This includes royalty and contractor’s profit. The figure of cost of 
extraction of bamboos on a large scale of both species, taking crooked 
and straight stems together, is put at Rs. 3 per 100 by the Divisional 
Forest Officer. This includes profits to the contractor but not royalty 
charges. Were the Rangoon supply to clash with that of a pulp-mill, 
it is possible that the price might go up 25 per cent. A safe figure on 
which to base the cost of extraction will, therefore, be Rs. 2-8 per 100 
stems of Tinwa, and Rs. 4 per 100 stems of Kyathaung. 
(9) Cost of landing dry internodes per ton at the factory site. 
Supposing Thonze to be selected as a mill site, the cost of landing dry 
internodes at the factory will be as follows :— 
(i) Cephalostachyum pergracile (Tinwa).—The weight of dry 
internodes yielded by one Tinwa is 7 - 6 lbs. (See Appendix 
I), and it requires 295 stems to yield one ton of dry inter¬ 
nodes. Therefore the cost of extracting 295 stems or, in 
other words, of landing one ton of dry internodes at Thonze 
at Rs. 2-8 per 100 comes to Rs. 7-6-0 per ton. 
(ii) Bambusa polymorpha (Kyathaung).—The weight of dry in¬ 
ternodes yielded by one Kyathaung is 15-4 lbs. (see Appen¬ 
dix I), and it requires 145 stems to yield one ton of dry 
internodes. Therefore the cost of extracting 145 stems 
or, in other words, of landing one ton of dry internodes at 
Thonze, at Rs. 4 per 100, comes to Rs. 5-12-9 per ton,
