CHAPTER III. THE FELLINGS. 



Section 1. Ihe general working schemes and calculation of 

 the possibility. 



37. Timber. Sal Working-Circle From estimates based on mark- 

 ings made by the writer in the Sealduba block, Apalch.-md forest :md 

 Lataguri block, Lower Tondu forest, it is anticipated that the yield in 

 timber will amount to about 55 cubic feet of sal per acre in the former and 

 40 cubic feet in the latter. The latter block has, however, suffered in the 

 past from fires so that the trees which have been removed are frequently 

 short and stunted. 



38. Firewood, The quantity of firewood available varies so much that, 

 it is difficult to make an estimate, but the yield may safely be taken at 500 

 cubic feet per acre where there is sufficient demand to warrant its 

 extraction. 



39. Mixed Working- Circles It is not anticipated that the yield of 

 timber will be appreciable. The outturn of fuel varies according to the 

 character of the crop. Taking the figures for 1904-05, the densely stocked 

 Sipchu block yielded 1,400 cubic feet per acre, whereas, in the thinly 

 stocked Pangjhora block, the firewood obtained worked out to only 300 

 cubic feet per acre. The average yield of all coupes worked under Coppice 

 with Standards amounted to 700 cubic feet per acre. 



Section 2. Period /or which fellings are prescribed. 



40. The most important fellings are the Improvement fellings which 

 will take 15 years to traverse the area under treatment. Consequently 

 fellings in all Working-Circles are prescribed for 15 years- 



Section 3. Areas to be felled annually or periodically: order 

 of their allotment. 



41- In each of the Sal Working-Circles the average yearly coupe 

 will be ith of the productive area of the Working-Circle, i.e., of the area- 

 stocked with sal and mixed forest, except in the case of Series It of Apal- 

 chand and the whole of the Lower Tondu Working-Circle where the annual 

 coupe will be about j^th of the sal area. In the Mixed Working-Circles ^th 

 of the productive area will be worked over annually. The whole area of 

 every Working- Circle will be open to the extraction of dry timber at 

 the discretion of the divisional forest officer. 



42. The order of the allotment of the fellings is given in the tabular 

 statement at the end of this chapter and for Improvement fellings, the 

 position of the areas to be worked over is clearly shown in the map 

 annexed to this report. 



Section 4. Nature and mode of executing the fellings. 



43. Sl Working- Circles: In these the exploitation of sal will include 

 the removal of : 



(a) all sal trees over 2 feet in diameter, 



(ft) all sal trees which show signs of deterioration being dead, 

 hollow, crooked, or top-broken and
