Thus the area surveyed should yield about 300,000 tons 

 of green bark and 5,000,000 tons of stacked fuel. As 

 the area surveyed is estimated to be one-sixth of the 

 total, the yield from the mangrove forests of the Arakan 

 Division may be put at 1,800,000 tons of green bark and 

 30,000,000 tons of stacked fuel. The Divisional Forest 

 Officer, Mr. Walker, gives it as his opinion that as man- 

 groves do not coppice, though the natural regeneration 

 from seed is excellent, it would be best to work the 

 forests by leaving standards as seed-bearers and give the 

 forests a forty years period of rest between each felling 

 cycle. Further, as the above calculations are based on 

 one sample plot covering only an acre, it would for 

 safety's sake be well to reduce the yield by one-third. 

 Working on that basis, with a forty years' felling rotation 

 and a two-thirds yield, the annual sustained yield of green 

 bark works out to 30,000 tons for the whole Division, 

 and 5,000 tons for the area which has been surveyed. 

 These estimates are probably below the mark, inasmuch 

 as the yield has been reduced by one-third of the actuals, 

 and the mixed mangrove and " Sundri " forests left 

 altogether out of account. 



While carrying out the work of stripping and collecting 

 the bark the figures of cost were carefully recorded, and 

 it was found that it cost Rs. 15 to cut and strip three 

 tons of green bark, i.e., the yield of one acre. Taking 

 carriage, establishment charges, cutting, stripping, and 

 stacking of fuel, etc., all into account, it is estimated 

 that Rs. 12 15 per ton would be the outside cost of 

 delivering fresh bark at either Sandoway or Kyaukpyu. 



The local officers think that labour would be always 

 available, and that extraction and delivery of the bark 

 to a factory could be arranged for with contractors. It 

 is, however, pointed out that owing" to the hard nature 

 of the wood and to the difficulty experienced in stripping
