paper, depends on the cost of production. Taking the figures arrived 
at by boiling Bambusa polymorpha or Kyathaung bamboo on a com¬ 
mercial scale and the cost of the raw material as given in Part IV, 
we arrive at the following figures of cost for manufacturing unbleached 
bamboo-pulp in or near Calcutta. 
Calculation based on a 46 per cent, yield on weight of air-dried material 
obtained by boiling with 18 per cent, caustic. 
1 . The amount of raw material required to make one ton of air-dried 
pulp is 2*17 tons. The cost of one ton of air-dried bamboo in Rangoon 
may, on an average, be said to be Rs. 10 (see Part IV), therefore 
the cost of 2T7 tons works out at Rs. 21-11-0. Freight from Rangoon 
to Calcutta Rs. 7 per ton or Rs. 15-3-0 for 2’17 tons. Total cost of raw 
material, to produce one ton of unbleached pulp in Calcutta, therefore, 
works out at Rs. 36-14-0. 
2. It requires 18 per cent, of caustic soda to reduce 2* 17 tons of raw 
material to one ton of pulp or a total of 7-8 cwts., say, 8 cwts. at Rs. 6 
per cwt. of fresh and recovered caustic works out at Rs. 48. 
3. Cost of coal, of which 1J tons are required to produce one ton of 
pulp, at Rs. 9 per ton = Rs. 13-8-0. 
4. Labour, superintendence, Rs. 10. 
5. Fixed charges, depreciation, repairs, etc., Rs. 10.

Were the pulp to be manufactured in Rangoon, the cost of the raw 
material would be reduced by Rs. 15-3-0 while the cost of the coal would 
be increased by Rs. 6-8-0, so that the cost of unbleached pulp in Rangoon 
works out at Rs. 109-11-0.
