Part V.] Pearson: Note on the Utilization of Bamboo. 83 
The conditions in this valley are identical with those in the neigh¬ 
bouring Ankola valley, which have been discussed above, so that the 
figures obtained by enumerating sample plots in that area will be 
applied here also. The growth in the Gund area being considered 
superior to that in the Kala Nudi or Gangavalli valleys, separate 
enumerations have been carried out, with a view to obtaining more 
reliable results. 
The area of 1st class bamboo forest in the valley proper is 14,264 
acres, while the outturn, according to figures given in Appendix IV, show 
a yield of 10,149 lbs. per acre, or a total outturn of 144,765,336 lbs. or 
64,627 tons. 
The 2nd class area in the valley covers 6,110 acres. From Appendix 
IV, we see that the yield per acre in this class of forest is 1,975 lbs. per 
acre or a total yield of 12,067,250 lbs. or 5,387 tons. 
In the Gund plateau there are 7,000 acres of 1st class forest. From 
the figures of the enumerations of five sample plots (see Appendix IV), it 
will be seen that the yield of dry internodes per acre is 28,968 lbs ; giving 
a total yield of 202,776,000 lbs. or 90,520 tons. 
Therefore the gross yield stands as 
follows :—

As has been explained in Part II, the rotation is fixed at five years 
so that the sustained yield works out to 32,107 tons of dry internodes 
per annum. As explained under (6) Outturn, page 78, this estimate would, 
be raised by 15 per cent, by including the nodes. 
(7) Lines of export. 
The Kala Nadi river is a broad stream which drains the whole.area. 
Floating is possible from September to March and even later, as water 
flows in the channel throughout the year. Owing, however, to rapids 
above Kadra and again below Bobrigadda, floating is difficult unless the 
supply of water is considerable. In the case of the valley forests, the 
distance, from which bamboo will have to be dragged to the stream, never
