3. The above figures give an average outturn of 9 5 lbs. of clean 

 Comparison with the rubfc >er per acre and -66 of a pound of clean 



previous season's rubber per tree. In the previous year, the figures 

 outturn. f outturn were very similar, being 9/4 lbs. per 



acre and '52 of a pound per tree, the outturn per tree being 

 reduced by the Bomoni Hill plantation containing 8 acres, in which 

 the trees are planted much more densely, and are, therefore, 

 smaller than at Charduar — the actual density being 92 trees per 

 acre in the former compared with only 14 per acre in the latter. 

 It is, however, noteworthy that the Bomoni Hill area yielded 9*5 lbs. 

 of clean rubber per acre, or about the same quantity as the average 

 outturn for the whole area of 322 acres worked over in the season 

 of 1898-99, a fact which tends to prove (the trees being of equal 

 age) that a densely-planted area does not yield more rubber than 

 one sparsely planted, while, on the other hand, it must have cost 

 more to plant out originally and to establish as a going concern — 

 see also remarks in paragraph 15. 



4. Compartments 3 and 4, which w r ere tapped for the second 

 Outturn of trees tap- season in succession, yielded practically the 



ped two seasons in same outturn as in the previous year, the figures 

 succession. for compartment 4, containing 1,499 trees, being 



•60 and '58 of a pound of clean rubber per tree for the first and 

 second year, respectively, while the few trees (25) tapped in com- 

 partment 3 this last season yielded '96 of a pound per tree, as 

 compared with "70 of a pound per tree obtained from the entire 

 compartment in the past year, the greater outturn this season 

 being doubtless altogether due to the fact that the trees operated 

 on were specially selected ones. 



5. Mr. Copeland, the Deputy Conservator of Forests, under 

 Method of tapping— whose careful personal superintendence and 

 different tools used. management all the operations were carried out, 

 reports that tapping was commenced in the first week in Decem- 

 ber, or six weeks earlier than in 1898, the object being to escape 

 the rain, which, however, does not seem to have been effective, 

 rain having fallen off and on during the whole tapping period. It 

 is also reported that three different tools were employed on the 

 work, compartments 6, 7, and 8 being tapped by Nepalese and 

 Assamese in the old and usual manner with kukris and dhaos.
