January 2, 1882.] THE TROPICAL AGRICULTURIST. 
to be reminded of the mode in which the bark is 
"removed," without injury to the cambium, and yet 
so thoroughly as to justify such language as "Replace 
the strip of bark thus removed in its original position 
without delay." "Thus loosened" would surely be 
a better description, and we should be glad to know 
what is the "suitable instrument" which Mr. Kara- 
lake's experience has led him to decide on ? A 
tortoiseshcll paper-cutter suggests itself to our minds ; 
or a bone or ivory spatula ? An ordinary knife used 
by an ordinary cooly would, we fear, result in injury 
to tho cambium ? With the bark simply loosened and 
at once replaced— kept in position by string and the 
edges filled up with cowdung or clay — we should 
have feared a process of readherence but for the 
result of Mr. Karslake's experience. The next great 
question is the effect of the atmosphere, and, especially, 
of battering rain on the loosened bark and its alkal- 
oids? Has Mr. Karslako satisfied himself that bad 
consequences will not ensue during tho period (con- 
siderably longer than Mr. Karslake's minimum of leu 
days in most cases, we suspect) during which the 
loosened bark remains on the tree ? No doubt, the 
adhesion of the strip at bottom and top is a safe- 
guard, but dots this entirely prevent deleterious changes 
in the alkaloidt ? Mr. Karslako recommends tho re- 
moval of the loosened strips only "after the renewed 
bark has appeared over the whole surface and is of 
Sufficient vitality to be able to withstand the heat" 
&c. To ascertain the state of the renewed bark will 
necessitate probably several movements of the old bark 
from its position, and each such process would, appar- 
ently, increase tho risk of chemical change in the 
alkaloid cells of the bark ? Mr. Karslake, having 
given t Uo public the benefit of the main principles of 
his discovery, will not, we feel certain, object to an- 
swer our queries as far his experience enabhs him. 
A correspondent writing from Maskeliya has pointed 
out the one objection wo felt and meant to express 
in regard to " B. H. C."'s valuable letter on cinchona 
nurseries. How ho, otherwise so well informed, came 
to recommend the painting green of conservatory glass, 
wo cannot conceive. Sure we are, from recent personal 
observation, that ho could not have seen green glass, 
or glass painted green, used in Java. Not certainly 
in the conservatories of the property in which Mr. 
Von Winning is interested any moro than in those 
tinder Mr. Moens' charge on the Government cin- 
chona plantation. The best conservatory glass is treated 
liko tho "moon glasses" of lamps, and white paint or 
whitewash can produco much the same effect with 
plain transparent glass. Wo took special note of tho 
fact that in tho case of the conservatories where Mr. 
Moens' grafted Ledgerianas are grown, the very device 
of shading with bamboo tats suggested by our Mas- 
koliy.. correspondent was resorted to. When ihe sun 
shono liorcely on either side of the conservatory, the 
effects wore modified by coverings of plaited bamboos 
belli' pui over the .sloping glu/rd loot. Indeed, much 
can bo done for the protection of plants by tho use 
of p] kited bamboo, without glass. Wo may also say 
at once that while Mr. Mooiib used tho porous chatties 
for g, i* initiating seed and growiug seedliug», ho had 
also largo aud flourishing nurseries ol I.cdguinnas iu 
long beds of mould, protected simply by grass-covered 
roofs facing each other, but with an open space be- 
tween to admit light and air. Right beneath the open 
space was the path between the two beds. The water- 
ing was performed by means of a syringe, which, in- 
clined upwards, produced a spray that fell gently on 
the plants. 
COFFEE IN SOUTHERN INDIA 
Wo give prominence to the following : — 
To the Editor of the " Ceylon Observer." 
Tellicherry, 19th Nov. 1881. 
Dear Silt, — We have the pleasure to enclose state- 
ment of exports of Coffee and Pepper from the Malabar 
coast for the year ending 30th June 1881. 
The present Coffee crop promises to be considerably 
larger than last. There seems to be considerable 
uncertainty as to the Pepper crop, but so far as our 
information goes, it points to only a moderate one.— 
We are, dear sir, yours faithfully, 
ALSTONS & Co.
