growing well and luxuriantly. In this plot 115 trees of 
poor growth, unbarked, were coppiced in May 1875, 
yielding only 218 lb. of green bark. Thirty- three stools 
died ; the surviving 82 average 9 feet in height and 5A. 
indies in girth, and the stools have from three to six 
4. No. Ill Plot, 1863.— 5-41 acres, shola soil, the 
portion above the road sub-soil indifferent, growth fair> 
the portion below the rood poor from wide planting and 
exposure to wind, nearly all succirubra barked seven 
times. 
5. No, IV Plot, 18G4, A.— 8-86 acres, above the road 
chiefly succirubra with a few officinalis, fair growth 
where the soil was shola, poor in places where; it was 
originally grass ; below the road succirubra and officin- 
alis mixed, very poor growth from wide planting aud 
exposure to the wind, the soil is also rather poor, all 
sin 
licfly 
about 5 acres of Officinalis 
owing to wide planting. 
In one spot 57 trees, succ 
run-hly in ' leti ' cr ! 8 73 ; no 
trees were cut, and 22 out 
died.

in the same place and standing ill eight rows with the 
above, 58 trees were also coppiced in May 1873, the 
suckers being left when the trees were cut ; only one 
stool is dead.

In another spot 200 succirubra were coppiced in May 
1871, when nine years old; suckers were left and only 
one stool died, the yield of the bark being 1,350 lb. 
green, drying to !■"•': lb. 
These 199 "ere again coppiced in March 1881, when 
ten years old i nil cnt Hush with the ground; no suckers 
left)! the yield of the lank being 3,365 Lb. green, dry-

to grow when I saw them on 1st of May, hut there 
had not of course been time for Ibis.

All the Succirubra and Officinalis have been harked 
eight times. 
Only abou! oighl trees are left, out of a quantity of 
Mirmuthu trees planted in ono place. This species is 
■Sported alwa; to die off, the blanks hove been tilled 
Bp with about 600 Pnbo scons trees (entered In Major 
Walker'.-, report a- supposed to be Anglica), which arc 
7. No. VI Plot, 1864, C— 7-87 acres, shola soil, 
planted with succirubra; aud officinalis in nearly equal 
proportions quite intermixed, growth good but thin hi 
portions owing to the original wide planting, all barked 
live times. In this plot £ acre (adjoining coppice in 
next block) coppiced in May and June 1879, 56 four times 
barked trees cut, 43 stools have grown well and 13 died. 
8. No. VII, 1864, D.— 17-04 acres, shola soil, succi- 
rubra and officinalis in equal proportions, growth very 
good, trees harked five times. In this plot a block of 
4§ acres of trees four times previously baiked was cop- 
piced in 1879 (from 31st of May to end of June), 
2,263 trees were cut and 2,091 are now growing. The 
were sawn through about 3 inches above the ground 
dzed over With a convex surface to nearly "flush 
the ground ; they hied excessively owing to the 
ss of the season ; hence I think the failures. The 
it growth of the remainder is most healthy and 
at could be desired ; each stool has from 1 to 3 
, 4 to 6 feet high ; there is also a late growth of 
sr stems, which, I think, should be pruned off, but 
lowson states that the Duke of Buckingham re- 
sd that these should be left. 
No. VIII Plot, 1864, K. — 11-58 acres, shola soil, 
ubra and officinalis, the former hi a greater pro- 
n ; growth of both very good and healthy ; succi- 
barked twice, officinalis barked five times. 
10. No. IX Plot, 1861, /■'. — 8-58 acres, shola soil, 
planted with succirubra and officinalis in nearly equal 
proportions ; growth of both very good, trees burked 
three times. 
11. No. A" Plot, 1865, 4.— 18-32 acres, in two plots, 
waste land intervening j first about two acres gross land 
planted with officinalis and a very few succirubra, very 
much exposed to the South-west monsoon; g',..v.il, ooor, 
trees barked five tunes. Second portion shola soil (ex- 
cept a small corner of grass land with about 1."'0 trees 
very poor growth) planted with Bucoirabra, wind-blown 
and growth poor except in a low protected portion 
where the growth is fair. 
12. No. XI Plot, 1865, D.— 12-96 acres, ahola soil, 
about nine-tenth sucorrubro, fair growth i.i portions, poor 
where wind-blown, ono corner very exposed, trees very 
poor ami dying out; about one-tenth officinal] . very 
good growth; all the tree* of both Bpocies burked font 
times. There are some PuboSOQnB tree-.. 
18. No. XII Plot, 1865, ('.— 12-13 norvs. slu.lu soil, 
succ irubm chiefly, officinalis iilnmt 3 a. i. s, all splendid 
growth, all barked -i\ times. The plantation ia too 
crowded in parts, the trees not being three feet apart ; 
the thill girthed tree* not reaching the light should ho
