3 * The above figures give an average outturn of 9 5 lbs. of cle an 
Comparison with the rubber per acre and 66 of a pound of clean 
previous season’s rubber per tree, fn the previous year, the figures 
outturn ‘ of 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 were 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. f or 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 dhqos ,
