It would, however, only be necessary to resort to the latter method in 
time of high flood or during the summer months. 
(8) Cost of extraction. 
(-£) By floating .—Owing to the thorny palisade above-mentioned, 
which exists round each clump, the cost of cutting is estimated at Es. 6 
per 100, which is a high figure, the cost of dragging to the river is put at 
Es. 3 per 100, and the cost of floating down the river from the centre of 
the area to Gumbala is put at Es. 2 per 100, a total of Es. 11 per 100. 
(ii) By carting .—The average distance is estimated at 12 miles by 
cart-road. A cart holds 33 bamboos and the rate per cart is 2 annas a 
mile. This works out to Es. 6-12 per 100 by cart, to which must be added 
Es. 9, the cost of cutting and dragging to the road, which works out to a 
total of Es. 15-12 delivered at Gumbala. To this must be added royalty 
charges. The price of bamboos on the coast is Es. 10 to 12 per 100, of 
20 feet length. 
(9) Cost of landing air-dry internodes per ton at the factory. 
From the results obtained by weighing culms cut in the sample plots 
(see Appendix IV), we get the following figures :—

The above calculations are based on a fairly large number of culms 
cut from various parts of the area, in good, fair and indifferent bamboo 
forests. The culms were weighed green, and again after the nodes had 
been cut out and the culms had been allowed to dry for about four months.
