SunEel Rengam. an estate IN Selan-
Igor. has a thousand acres which have
been in bearing for some time. as well
as more which win be coming on from
time to time. Shares In this company
are selling at an advance OF 500 per
cent. Then there is a very large es-
tate owned by chInaman in Malacca,
thirty or forty miles inland, which has
1.-TWO or three thousand acres in bearing
or soon TO come into bearing. Besides,
there are many other plantations of
varying acreage.
/ The methods of tapping vary. Per-
haps the most common is the so-called
modified herring-bone incision. A sim
gle vertical channel is made down the
bark with gauge not deep enough
F, to pierce the cambium or growing part
of the bark, and which is simply a
channel for the latex to run into from
the incisions, which are made on each
side branching obliquely from this, or
rather extending into 1t.
These incisions as they cross the
ducts which pass vertically up in the
| bark, and which are stored full of
latex under considerable pressure,
cause the latex to flow and carry 1t
down into the central channel, along
which 1t runs into a cup placed on the
ground or hung on nail placed under
a small tin spout pushed into the bark
of the tree. Another good method is by
the single "v'' incision, previously men,
toned, with a short central channel
leading from its apex down to a cup
placed beneath. Whatever kind of in
cision is used, every other day, or on
some plantations every day. a thin slice
of the bark from its surface down
nearly to the wood is shaved off the
under margin of this incision, which
re-opens the lactiferous ducts and
starts the milk flowing again. This is
kept up for month, or even two
months IL the tree keeps on flowing
well. Thus the oblique incisions get
wider and wider from day to day until
at the end of the series of tappings
it is one and one-half inches wide. AT
the end of six months in the case of
the modified herring bone incision or
three months in case of the single ''V''
incision, the other side of the tree is
tapped in the same manner. The best
implement. after the first incision, is
a farrier's knife, as the rounded ex-
tremity of the blades can not injure the
wood and leaves strips of cambium, or
the whole cambium, from which the
bark grows very quickly. The flow is
small at first, but reaches its maximum
in four or five days.
In this connection it was remarkable
to me how quickly the bark grew over
the places where the tapping had been
done. in three to six months where
the cambium Qnner or growing part
of the bark has not been injured or has
been left in strips on the wood, and
in nine months where it has actually
been stripped off the wood, new bark
has grown entirely over the wound to
la level with the remainder, and Incl
sions into this new bark will cause the
latex to flow as freely as though no
former incision had been made. AL
though, in the natural order of things,
this new bark would not be touched
for four or five years, as there is other
surface to tap before that time yet it
is a very important thing to be able
TO have all the lactiferous ducts re-
established so thoroughly and so soon
after tapping so as to give new surface
when it does become necessary to use
the same area of bark over again.
This reduces the whole tapping to a
system. The wood is never cut into.
and by the best methods the cambium
is not entirely removed. In fact. the
