the crop, the number of climbers which require cutting, and the number of dead 

 and dying trees, it is advisable to treat the forest to two short periods of im- 

 provement fellings of 10 years each rather than to one larger period of 20 years. 

 The great majority of the -promising teak trees are from 3! ' feet to 4^ feet in 

 girth, a large yield from selection fellings cannot therefore be expected for 40 

 years, but a considerable number of the larger trees will be mature in 20 years and 

 a fair yield can then be expected. It is assumed that the exploitable girth limit 

 will be taken at 6'. 



ARTICLE 2. The exploitable age. 



31. This is a consideration which is at present not taken into account. Data 

 should be collected and ring countings made to ascertain what is the true exploit- 

 able age. Full details as to what may be cut r,re given in the felling prescriptions. 



CHAPTER III. THE FELLINGS. 

 ARTICLE I. The General Working Scheme. 

 Calculation of the possibility. 



32. The total area of the forest is 26,960 acres exclusive of iSS acres of 

 the Bori forest village. For convenience of working the area has been divided 

 into 2 felling series of 10 coupes each: thus the mean annual size of each coupe is 

 1,348 acres. The general working scheme is to go over the forest with improve- 

 ment fellings which will include thinnings as well as the removal of over mature 

 trees during 2 periods of 10 years each. The possibility is not defined except by 

 the area of the annual coupe and the felling rules given in paragraph 36 below. 



_ 33. The sub-divisions of the coupes and the felling., series have been 

 retained as in the old working-plan, as for purposes of carrying out improvement 

 fellings they are sufficient. These sub-divisions, however, could probably be 

 altered when selection fellings are introduced. By that time also a fuller know- 

 ledge of the forest will have been obtained. The Dhain Block, 1 1 ,445 acres 

 (new Bori), has been excluded entirely from the prescriptions of the working-plan 

 although it was included in the old plan. This block lies to the west of the 

 Sonbhadra River and with a few exceptions is similar in character to much of the 

 Malni Block of the Bori Range to which properly speaking it belongs. The 

 Sonbhadra River forms an excellent natural boundary. 



ARTICLE 2. Period for which the fellings have been prescribed. 



34. The provisions of this plan extend to 10 years in which time the whole 

 forest will have been treated to improvement felling. It will probably be thought 

 advisable at the end of this period to subject the forest to another 10 years of the 

 same treatment. 



ARTICLE 3. Areas to be felled annually or periodically: order of allotment. 



35. The coupes have been retained as in the old working-plan with the 

 exception that as coupes i to 5 were worked over coupe 6 now becomes coupe i 

 and so on in sequence : paragraph 48 of the old plan gives the reasons for the 

 order of allotment: it is quoted below : 



" The coupes will be annual. The first coupe in each felling series has been 

 chosen on an export line and at its outlet, and the rest follow progressively away, 

 but in such a manner that those with the smallest resources come last. This 

 allotment of the coupes will also facilitate the economic construction of roads." 



_ Under a system of improvement fellings of so short a period it does not seem 

 advisable to alter the above arrangement. But before selection fellings are . 

 introduced the order of allotment might possibly be changed owing to the intro- 

 duction of that system, and in the light of more knowledge on the subject, which 

 will have been obtained during the period covered by the improvement fellings. 



ARTICLE ^.rNature and mode of executing the fellings -. forecast of 

 condition of crop at their conclusion. 



36. The improvement fellings will be made in the interest of teak; where 

 no_ teak occurs the more important inferior species such as beja, shisham, tinsa, 

 saj, tendu, lendia will be considered. Teak will be found at its best in such 

 places where there is a fair admixture of these species.
