Capital in Agriculture.
‘As we have shown in detail in a book
upon Agriculture in the Tropics, shortly
to appear, progress in agriculture proper
depends first upon progress or proper
equipment in what we may call the
preliminaries to Agriculture, These are.
roughly : (1) land, (2) climate, (8) popula-
tion and labour, (4) transport, (5) capital
or money, (6) drainage and irrigation,
(7) tillage, (8) education, and (9) crops.
Now land, climate, population, trans-
port (to a very large extent), irrigation,
tillage (to some extent), education (to
some extent), and crops are satisfactorily
enough arranged in Ceylon. There
remains capital. Asa late President of
the United States remarked, finance and
transport are the keys of progress. So
convinced were we that this was th®
only sound order in which to deal with
agricultural problems, that the very first
paper read at the first Meeting of the
Board of -Agriculture was by ourselves
on Co-operative Credit Societies, and we
have preached this doctrine to some-
what unwilling ears ever since, and
have had something about it in practi-
cally every number of the ‘‘T.A.”
The tide is beginning to turn, and the
Society is displaying an _ increasing
interest in this question. It must be
clearly recognised that no serious pro-
gress is possible without money, but
once the expenditure of money is started
on the right lines, it breeds more
money. At present the - villager is
helpless in the grasp of the local money
lender, and cannot afford to borrow a
penny even if he thinks it probable that
it might bring in twopence or three-
pence. Manuring of rice, transplantation
of rice, cultivation of vegetables, manur-
ing of coconuts, sale of produce outside
the village, and all other suggested im-
provements demand money for a start.
Mr. McCall gave some interesting facts
about Egypt at the last Meeting of the
' Board. There are no white planters
there, and at first the natives were
averse to manuring ; but, once convinced
by ocular demonstration that it paid,
and provided with the necessary money
by Agricultural Banks or Soci ties,
they took it up so strongly that within
four years Egypt was consuming
£175,000 worth of artificial manure a
year. If the Ceylon villager is not to
sink to the position of a hewer of wood
and drawer of water, he must be helped
to get financially upon his legs, and the
new Government departure of loans to
the agriculturists will be watched with
great interest. How best to give
security for the money will be one of
the problems. It has been suggested
that headmen, who are commonly men
of more or less substance, should give
the security, and lend to their villagers
in cases where they feel that is safe.
But so many villagers merely lease the
land on which they work that there
may be difficulty about the security,
As Government is now going to attend
to the money question with regard to
paddy cultivation, we would recommend
that the efforts of local societies be di-
rected to other crops, to their establish-
ment, their cultivation, tillage, and man-
uring, and their sale in the best market.
For all these ends money is necessary.
There is an enormous difference
between the agriculture of planters’
estates, whether European or native,
and that of the villager—the former
/

getting a larger return at less cost. But
it must not be supposed that this is all
due to the superior Education or training
of the former; rather it is largely, at
any rate, to be attributed to the fact
that he has capital at his back.
It may be well to remark that there
are other preliminaries to agriculture,
conspicuous among the.a being trans-
port, and it will be idle to expect much
progress in a village unprovided with
roads. Here the most that can at
present be hoped for is that the villager
should get free of the incubus of
debt.
Education, again, is very important.
Travelling about the country, and
noting the signs of agricultural pro-
gress, new crops, &c., and enquiring
about them, we have very commonly
found that they owe their origin to the
local school garden, and are often, in
fact, cultivated by a boy being educated —
at the school.
Tillage isa thing as yet mainly prac-
tised in paddy-fields, but nothing can be
done in the way of improvement with
out money for a start.

CASTILLOA OR CENTRAL
AMERICAN RUBBER.
By WILLIAM FAWCETT, B.SC., F.L.S.,
Late Director of Public Gardens and
Plantations, Deputy Chairman of the
Agricultural Society, Jamaica.
Para rubber (Hevea brasiliensis) has
supplied such a very large proportion of
the rubber used in the arts, the area of
its natural habitat isso vast, and the
tree has been planted so extensively,
that the attention of growers of rubber
has been mainly directed to experiments
with italone. But, as the conditions for
the successful cultivation of the Brazilian
tree are not to be found everywhere in
the tropics, it is well to experiment also
with other plants, and the most pro-
mising of these is perhaps the Central
American rubber, a species of Castilloa.
Species.—Some species of this genus,
e.g., Castilloa tunu, are worthless as
producers of rubber, and before using
the seeds of any Castilloa. tree it is
important to ascertain whether the
latex of that tree yields rubber of good
quality. Castilloa elastica is the species
that has been considered the main
source of Central American rubber.
Professor Olsson-Seffer thinks that
Castilloa luctiflora gives a more ample
flow of latex. It is to be honed that he
will favour us with the results of
further investigations.
Situation.—Experience in growing
Castilloa under various conditions in
Jamaica points to several factors as
being important for the _ successful
growth of the tree. It will not grow to
advantage if the proportion of clay in
the soil be too high, otherwise it does >
not appear to be very particular. A
loamy soil is the most suitable. The
drainage must be good; the unsuit-
ability of stiff clays may be due to the
want of sufficient drainage, and may
perhaps be overcome by making drains.
The rainfall should be at least 70 in. per
annum; but if less, and the deficiency
can be supplied by irrigation, the trees
will grow and yield quite as well. A tem-
perature which varies between 70° and
90° F. is suitable; the elevation is not
material if the temperature does not
fall much below the lower limit.
Shade.—Castilloa trees are found in
nature on the edge of forests and in
clearings. Overhead shade is not re-
quisite in the wild state, and has not
been found essentialin plantations. The
stem requires some protection from the
sun, but this can be provided in plan-
tations by the shade of the neighbouring
trees. Overhead shade is not detri-
mental if not too dense, but it lengthens
out the bole of the tree unnecessarily.
Clearing Ground,—If woodland has to
be cleared, this operation should be
done thoroughly from the first. Some
recommend thata few trees should be
left here and there to afford shade for
the seedlings and young trees, but they
must be got rid of eventually, and the
cutting down and removing them leads
to injury and destruction among the
rubber trees. The large trees should be
sawn into boards for the erection of
sheds at a later period; the smaller
timber will be useful as posts ; the small
useless branches should be heaped and
burned in such a manner as not to set
fire to other trees or bush close by. The
ashes are good manure,
Distance apart and Catch Crops.—The
distance at which Castilloa trees should
be planted at first depends upon whether
they are to be grown with bananas
or other catch crop, or alone. If the
soil is suitable for bananas, and the
locality one where it will pay to grow
them, no other catch cropis anything
like as good. The bananas should be
planted in March at distances of 15 ft.
apart, and the Castilloa seedlings may
be put out about September, each seed-
ling in the centre of four banana plants,
or, if the cultivator or plough is used to
keep down weeds, the Castilloa must be
planted in the banana rows between the
bananas. The bananas may be grown
for three or four years, and then they
should be gradually thinned out as the
Castilloa trees spread their branches.
If bananas are not suitable, corn (maize)
and gungo or pigeon peas (Cajanus
indicus) may be used as catch crops
and temporary shade. The fields should
be lined out in March, and stakes put in
to mark where the Castilloa plants are
to be put out. Then the gungo peas
should be sown so as to leave a clear
space of 4 ft. round the stakes, and the
corn not nearer than 7 ft. The gungo
peas will not last more than two or three
years, but by that time the young
Castilloa plants will not require any
more nursing: The corn will not inter-
fere with the Castilloa if kept ata safe
distance, and if there is a market for it
the returns will help to pay expenses.
Even if there is not a market for the
gungo peas, they will increase the
introgen content of the soil, besides
Gums, Resins,
forming a slight shade for the rubber.
The cultivation of the soil will be of the
greatest benefit to the growing rubber
plants. If no catch crops are to be
grown the distance for the rubber plants
may be 6 ft. at first, to be thinned out
eventually to 18 ft apart.
Seeds.—The seeds are massed together,
and are covered with an orange-coloured
flesh. When ripe they drop from the
trees, and if left undisturbed numbers
of seedlings will soon spring up. Itis
best, however, to collect themas they
fall, and sow them ina seedbed. There
should be no delay in sowing them, for
they soon lose their power of germin-
ating. Professor Olsson-Seffer was in-
terested in some experiments to deter-
mine the best ageat which to collect
seeds from the trees. Until the result
of these experiments is known, I should
advise that seeds should not be sown
from trees until they are fully six years
old, when the latex has lost its resin.
Sowing Seed.—The seed-beds should be
thoroughly forked and raked until the
particles of soil are quite small and fine.
The seeds should be lightly pressed down
so as to be just covered by the soil, and
at a distance of about an inch apart from
each other. A thin layer of dry grass
may be scattered over the bed, and then
a good watering given from a watering-
pot with a fine hose. The soil should
afterwards be kept only just moist. not
too wet, and carefully weeded. When
the seedlings are 3 or 4 in. high the soil
may be loosened with a fork and the
seedlings taken out, and either planted
again in boxes ata distance from each
other of 3in., or set out at once in their
permanent places in the field. If they
can be constantly inspected in the field
and kept weeded, and the weather is
favourable, itis better to put them out
at once; but if not they may be kept in
the boxes until they are6or7 in. high,
and then transplanted, when they are
not so liable to be the worse for any
neglect in the open. It is still better to
sow the seeds at once, as _ soon as they
fall, in the permanent positions already
marked out for them in the field. Three
or four may be sown at the stake at
about 3 in. from each other.
Planting out.—If bananas have already
been planted during the previous March,
the fields should meantime have been
run over with the plough or cultivator
to keep down weeds, and to establish a
dust mulch on the surface. The seeds
may be sown as they fall, or the young
plants may be put out about September,
either in the rows between the bananas,
so as to be 1a ft. apart when the bananas
are removed, or they may be planted
each in the centre of four bananas.
[JANUARY 1909,
Thinning out.—The seedlings should
be continuously watched and carefully
thinned out, leaving at the end of the
first year only the most promising one
at each stake. If none of the three or
four has turned out well, supply from
the nursery which had been made for
the purpose.—Tropical Life, September, —
1908, Vol. IV., No. 9.
THE RUBBER TRADE OF BRAZIL.
Ceylon rubber producers will be in-
terested in a comment which appears
in the Board of Trade Journal upon
the trade in Brazil, Referring to the
ready disposition shown among British
capitalists to invest in the acquisition
of Brazilian rubber-producing properties,
the Journal shows that investments of
this nature have not invariably been
successful, and advises that such under-
takings should be entered into with
the greatest circumspection. It is
pointed out that the remarkable develop-
ment of the rubber trade in Ceylon
and the Straits Settlements, as well as
in Africa and Mexico, has made a great
change in the position, and is likely to
change it still further. Up to this time
Brazilian producers have apparently
attached little importance to possible
competition from these sources, but now
some among them are beginning to view
the matter as fraught with more danger
to the interests of their industry than
they had supposed. It is even argued
that within a period of ten years the
practical monopoly of Brazil in this
important and increasingly valuable
production may be at an end. The
Board of Trade commentator says it
certainly appears that, other conditions
being favourable, the systematic process
observed in the countries named, to-
gether with the greater cheapness of
labour, transport, and other items
affecting the industry will place these
cultivators in a vastly superior position
to those of Brazil, where the expenses
in every branch of the industry are
on an extremely high scale, and where
the risks to health in the process of
collection, with other contingencies,
constitute a heavy handicap.—-Indian

CASTILLOA ON THE ISTHMUS.
OF TEHUANTEPEC.
By J. L. HERMESSEN, of Chiapas,
Mexico.
(Continued from page 513.)
Much stress has been laid upon the
danger, in tapping, of cutting through |
the cambium layer into the wood; and

it cannot be denied that incisions
around the circumference of a tree, of
such depth as to penetrate the cambium
layer throughout its entire length, is
apt to cause rot, in which certain insects
are likely to deposit their ova, the
larve proving in many _ instances
destructive of, or at least injurious to,
the trees,—this being particularly the
caso where the “machete” was used
as the tapping instrument. But with
a modern tool of such design as_ to
prevent too deep an incision being
made, it has been found that a cut
just impinging upon the cambium layer,
and piercing it only at intervals, has
not only given, the greatest amount of
latex, but seems to be necessary to
the formation of new bark. Any incision
failing to reach and penetrate, at in-
tervals, the cambium layer will result
in a mere hardening of the surface of
the cut without any attendant renewal
of the bark. It has been noted by
many that the touching or cutting of the
cambium layer effects a restoration or
new growth of the bark within a period
of sixty days, the bark continuing to
grew and fill up the entire incision
within a year.
Doubt yet exists as to the best time
of the year in which to conduct tapping
operations. Mr. James Collins, in his
Report on the Caoutchoue of Commerce,
published in 1872 under the auspices
of the British Government, states that
in Niearagua (where the climatic con-
ditions are generally similar to those
obtaining on the Isthmusof Tehuantepec)
the most favourable time for tapping
was during the months of March and
April, when the change of foliage was
taking place. The following quotation
from Mr. O. F. Cook's monograph on
Castilloa* also bears upon the point:
“The indications are that (internal)
pressure attains its greatest intensity
in trees which are exposed for a part of
the time to a relatively dry atmosphere,
and which are accustomed, as it were,
to pump water rapidly to supply the
leaves. Such trees may, onthe contrary,
yield no milk at all when the water
supply is deficient. It may be expected,
therefore, that open culture will require
much more careful attention to the
time of tapping.” The best results,
thus far, have been obtained on the
Isthmus of Tehuantepec from tappings
made during the early months of the
dry season (Febuary and March), before

5 Saps and Excudations
the weather has become very hot and
when the coolest nists and mornings
occur. In April and May, when the
maximum temperatures of the year
are attained, the deciduous character
of Castilloa becomes most marked ; and
this is the period during which the
tree is generally supposed to be in its
most quiescent state, and to have the
last recuperative power. On the other
hand, in the wet season planters are
confronted by the physical difficulty
of collecting the latex. Some contend
that tapping can best be done durin
the occasional (and very uneertain)
rainless spells of the wet season; an
it is upon the latter hypothesis that
two tappings per year for Castilloa
come within the range of possibility.
It has been noticed that the latex is
in a much more fluid condition during
the early morning hours, turgescence
increasing as the diurnal heat reaches
its maximum.
What the financial promoter and the
expert prospectus-writer had long since
settled to their own entire satisfaction
and that of a trusting public, with
the same fatuous positiveness as your
orthodox theologian dogmatises on the
future life—the question of yield—is still
to the planter, who should know most
about it, largely a sealed book. If he
be honest, he will confess that he
knows as yet very little aboutit. What
he does know, however, is thata_ six-
year-old tree will not give 1 Ib. of
rubber. Trees of unknown age, in a
state of nature, have yielded as much as
4 and 51b. of rubber at one tapping ;
and there are apparently well-authenti-
cated records of yields of triple that
quantity from very large and presum-
ably very old trees. Undue weight
seems to have been attached to the
generalizations of Herr Th. F. Koschny,
of Costa Rica, in this respect. Hisclaim,
for instance, of a yield of 33 lb. of rubber
from wild trees, 8 or 9 years old must be
accepted cum grano salis. There are, as
a matter of fact, no recognised means of
definitely determining the age of wild
rubber trees; the all-important element
in the case in point is, therefore, hardly
more than one of conjecture.
With regard to cultivated trees, whose
ages, with very few exceptions, have not
yet passed the eighth year, there appears
to be a strong disinclination on the part
of planters in Mexico to tap their trees
to the full extent of their possibilities,
owing mainly toa reasonable fear that
permanent injury may result through
incautious tapping in the light of present
knowledge; and since in the case of
Castilloa, as with all caoutchouc-produc-
ing genera, notable constitutional dif-
Gu ms, Resins,
ferences occur, both as to size of tree and
yield of latex, under similar cultural
conditions, the results obtained from
individual trees do not form satisfactory
evidence upon which to base a conclusion
as to the average yield of many thousands
of trees of like age. Hence, trial tappings
of single trees, or groups of limited
number, of equal age vary very consi-
derably. Thus, we have trees, or groups
of trees, producing 1, 2 and 3 oz. of
rubber, others ranging as highas from 4
to6oz. at one tapping. With such vari-
able data to go upon, the difficulty of arri-
ving atatrue average yield for a planting
of perhaps half a million trees is obvious.
Tentative experiments made in this
district would indicate that trees grown
under the most favourable conditions of
soil, &c., may be tapped twice a year
with equal results; but it would seem
premature to say with assurance that
the trees covering a large area could be
safely subjected to such a drain upon
their vitality until they had attained a
greaterage. Torepeat, however, selected
groups of trees of the age above men-
tioned have withstood a second tapping
in a year without visible injury.
With regard to local soil conditions, it
has been stated that ‘‘ the oldest portion
of the Isthmus evidently began its
superaquatic existence at.a compara-
tively recent period—geologically speak-
ing ”’*—.and that much of the geological
formation of the Eastern Atlantic
versant of the Mexican cordillera to-
wards the Isthmus of Tehuantepec is of
similar late origin is indicated by the
presence of stratifications of marine
shells and primordial ooze, where sub-
sequent aqueous erosions have occurred,
creating, in the cycle of topographic
changes, more or less abrupt undulations,
ridges and valleys, with occasional hills
reaching to a height of 150 ft. between
depressions. In the immediate neigh-
bourhood of the sea and the riverine
estuaries alluvial deposits are found, but
these have proved unsuitable for most
cultural purposes, owing to the shallow-
ness of the water basin. On theapproach
to the sierras, ‘‘mesas,” or benchlands,
occur of an entirely different structure,
these being made up of granitic or other
primitive detritus, incorporated with
abundant vegetable matter. Such lands,
unfortunately, are not encountered in
any large areas. The soil of the district
herein referred to is composed of clayey
loams, overlaid in parts with beds of rich
black humus of the greatest fertility.

6 [JANUARY, 1909,
The climate of the Atlantic side of the
Isthmus of Tehuantepec has three well-
efined seasons-—namely, the wet season
Proper, commencing usually the last week
In May or the first week in June, andcon-
tinuing till the end of October ; the lighter
wet or “norther” season, extending
over the months of November, December,
January and February; and the dry »
season, comprising the months of
March, April, and May. The annual
rainfall is between 90 and 120 inches,
with a very favourable distribution,
three-fourths of the total precipitation
taking place between June and October,
while from then on until the approach
of the dry season frequent showers fall,
with much mist and drizzle. No month
of the year is wholly free from rain,
occasional light showers occurring even
during the height of the dry season,
when the greatest heat of the year is
experienced, the Mercury fluctuating
between 80° and 90° F. in the shade, and
sometimes marking 100°. Anappreciable
diminution in temperature ensues dur-
ing the wet months. the average range
being from 75 to 85° E., while during
the cooler months, from November
to February, the average temperature
is between 60 and 80° F., once ina while
falling as low as 55° F. in the early hours
of the morning. The lowest temper-
ature recorded by one observer over a
period of nine years was 50
occurring in the month of January. .The
relative salubrity of the climate of the
Isthmus of Tehuantepec as a whole, as
compared with that of similar latitudes
elsewhere, is quite remarkable, this
continent being cooler under the equator
than any other, owing to the expanse
of sea surrounding it and the more
elevated configuration of the land.
The vegetation of this region presents
to the trained eye a strictly tropical
aspect, the forest growth consisting
almost entirely of tropical genera, such
as mahogany, Spanish cedar, lignum
vitae, giant representatives of the ficus
family, the stately ceiba, with its wide-
spreading, buttressed trunk; numerous
examples of sapotaceous trees, ineclud-
ing the lofty ‘‘Mamé” and the “chicle”’
(from which American ‘‘chewing-gum ”
is made, and which also produces one
of the best of all wild tropical fruits, ~
namely, the ‘‘zapodillo,” or, in the verna-
cular ‘‘ chico zapote”); while many ano-
naceous trees-occur, some of which bear
edible fruits—close relatives of the
famous custard apple, or ‘“ chirimoya.”
Hard-wooded shrubs of various orders,
and large-leaved plants from the under-
growth, with scattered groups of deli-
cate slender-stemmed palms, belonging
principally to the genus Chamoedorea.

Sheltered in the ravines, and generally
near the edge of a water course, tree
ferns add their feathery beauty to the
leafy labyrinth of the jungle, notwith-
standing the low elevation of 300 feet
above sea-level.
Clustering the more open parts, and
fringing the banks ot rivers and streains,
are groves of tall, graceful palms, incluc-
ing Attatea cohune and the spiny Acro-
convia; while now and then a royal palm
(Oredoxa regia) rears his noble head
over legions of lesser kind. (The writer
is informed by a friend, who is more
than an amateur botanist, that he has
identified fourteen indigenous specimens
of palm on the Isthmus of Tehuantepec.)
Interlacing with fantastic festoons the
upper branches of big trees, or reaching,
like the halyards of a ship, to the earth,
are great lianas, or climbing vines,
which, when in flower, display enchant-
ing colour effects, clothing the tops of
the highest trees with brilliant mantles
of purple, yellow, and crimson. These
seem to be made up chiefly of representa-
tives of the Leguminose and Bignonia-
cece. Many trees, again, are adorned
with a profusion of epiphytic growth—
ferns, bromelias and orchids. Amongst
the latter may be found Chysis bractes-
cens, with its beautiful, waxy-white
sepals and petals, and labellum tinged
with yellow; the pretty and fragrant
Epidendrum atropurpureum, H. cochlea-
tum, EH. alatum, EH. radiatum, and &.
stamfordianum ; a species of Oncidium
very similar in foliage and inflorescence
to the well-known O. cebolleta (found
at higher altitudes in Mexico); O. luri-
dum, MB sphacelatum, one or two showy
species of Stanhopea, anda number of
other genera of merely botanical interest.
Four indigenous species of vanilla,
including V. planifolia, also have their
habitat in these forests. No attempts
have been made, however, to cultivate
the plant here.

tion and data embodied iv the fore-

RUBBER INDUSTRY OF JAPAN.
The following particulars relative to
the rubber industry of Japan have been
received by the Board of Trade from the
British Commercial Attaché at Yoko-
hama (Mr. HK. F. Crowe) :—
The Osaka Asahi publishes an article
dealing with the proposed establish-
ments of two rubber factories, in which
British, French, and Japanese capital
will be invested. From this account it
appears that a Frenchman who is in-
terested in various other enterprises in
Japan has arranged a combination with
two British companies. One factory
will be situated at Osaka and will make
tyres and other rubber goods, while a
smaller factory will be built at Kobe for
the manufacture of rubber tubes for
feeding bottles. The idea is to start
with a moderately small capital of
£75,000; as the business develops it is
proposed to increase the capital and to
start exporting rubber goods to China,
Korea and other Eastern markets
At the present moment there are six
rubber companies in Japan with a total
capital of £45,000. Of these the oldest
and largest is the Japan Rubber Com-
pany of Tokio, started in 1900 and
having a capital of £18,000.
The others are as follows :—
Name. Town, Capital.
Tokio Rubber Co. Tokio £8,000
Meiji Rubber Co. Tokio £7 000
Sakatsuchi Rubber Co. Tokio £8 000
Japan Rubber Ball Co. Osaka £2,000
Imperial Rubber Co, Osaka £2,000
The raw material, on which there is no
duty, is all imported from abroad. The
following statistics show the quantity

and value of the imports of rubber and
rubber goods into Japan during the past

THE FUTURE OF THE CAMPHOR
TRADE.
Hor some time past the cultivation of
the Camphor tree for commercial pur-
poses has been carried on, even in For-
mosa, its native country, under the fear
of a diminishing _ trade. Synthetic
camphor has been talked about for many
years past, and, like the chemical pro-
duction of indigo, which has threatened
the Indian planters. with extinction,
there has been and is still the fear of
the triumph of the chemist over the
planter in the future supply of the
Camphor market. Incidentally it may
be stated that under the new Patents
Act, which came into operation recently,
a factory has been erected chiefly for the
chemical manufacture of indigo by a
German firm on the Manchester Ship
Canal near Chester, and no one can tel
how soon a similar factory for the pro-
duction of camphor may follow.
The competition between the two.
kinds of camphor is sufficiently apparent,
when we find both products side by side
in the London market, with a strong
tendency by the makers of the synthetic
product to bring the prices of their
article considerably below those of re-
fined natural camphor. With the pre-
sent camphor supply in the hands of
such shrewd commercial people as the
Japanese, and with the introduction of
the Camphor tree into various other
countries, a process that has been going
on for several years past, the future of
the European trade has become a kind
of Chinese puzzle. Thus the Japanese
Minister of Finance, in an official report
issued a short time since, drew attention
to the circumstance thatif Japan wished
JANUARY, 1909. ! 9
to retain the control of the camphor
trade in future years, and to meet the
ever-increasing demand, she must bestir
herself by extending the cultivation of
the tree, which requires forty or fifty
years’ growth before avy satisfactory
return can be expected. Hefurther said
that, while thus encouraging the pro-
duction and manufacture of camphor, the
Government intended also to promote the
exportation of the finished article, and
commissioners had been sent to Kurope
and the United States to investigate the
conditions affecting thedemand, About
the same time that this Report was
issued a statement also appeared from
the United States Consul at Tamsui, of
an interview with the chief of the
Camphor Bureau of Formosa.
it is stated that the manufacture of
camphor in Formosa affects only those
trees of fifty years old or upwards, inas-
much asthe cutting down of trees of a
less age is forbidden. Recent investiga-
tions indicate that the supply of mature
trees will, at the present rate of cutting,
become exhausted in less than fifty
years. The old trees now standing are
confined to the mountainous eastern half
of the islands in regions, for the most
part, inhabited by savage tribes. These
mountains are covered with dense
jungles, and the work of making roads,
in order that the camphor forests may
be rendered available for profitable
exploitation, must involve the expendi-
ture of much time and labour, besides
which the sanitary conditions of the
country are such as to produce fever
among the labourers. A thousand coolies
_were taken by a Japanese company
into the Daito prefecture a few years
ago for the purpose of exploiting the
camphor forests, and 33 per cent. of the
workers were completely incapacitated
by fever. The greater part of the
camphor at present produced in the
Island comes fromthe Toen prefecture.
Between 1900 and 1906 the Japanese
Government planted about three million
young trees, and it is intended to follow
this up by planting 750,000 in each
successive year.
There are said to be two distinct
varieties of the Camphor tree grown,
one prodacing the camphor of commerce
and the other producing only camphor

oil. There would appear, however, to
be some mistake in this, as will be seen
later on.
Private firms in Formosa wishing
to engage in the cultivation of Camphor
trees are supplied with young plants
from the Government nursuries. Al-
though the Customs returns for China
show that 12,000 piculs of crude camphor
were exported from that country in
1906, yet the Kormosa authorities fear
no competition from that source, and
the reports of camphor planting in
Ceylon, Florida, Texas, aud Mexico do
not disturb the prospects of the
Formosan product in the eyes of the
authorities. They contend that the
more Camphor trees planted the less
likelihood there will be of the successful
production of an artificial substitute.
The subject is interesting from two
points of view, First, it must be remem-
bered that pharmaceutically genuine or
natural camphor is alone acknow-
ledged by the British Pharmacopoeia,
while synthetically-prepared camphor is
principally and increasingly in demand
for the manufacture of celluloid and
smokeless powder. Referring to the
statement that two varieties of the
Camphor tree are grown in Formosa,
one yielding camphor and the other
camphor oil, we may quote from a
recent report of Sir A. Hosie, Acting
Commercial Attaché to H. M. Legation
at Pekin, where he says ‘‘ Not only is
camphor distilled from the camphor
wood chips upcountry, but the oil
resulting from this distillation is brought
to Foochow in airtight old kerosene
tins, ve-distiiled, and made to yield some
dC per cent. of its weight in camphor.”
The process is described as a very
crude one, the oil being poured into the
retorts, and the distilled oil, after passing
through the worm, is received into
kerosene tins, which are placed in tanks
ot water, where they stand for twenty-
four hours to cool and to deposit the
camphor in the bottoms of the tins.
“The oil 1s then poured off and redis-
tilled as many as sixteen or seventeen
times, until the camphor has all been
extracted.”—Gardeners’ Chronicle, Vol.
XLIV., No. 3538, October, 1908.

OILS AND FATS.
RECENT RESEARCHES REGARDING
THE GERMINATION OF THE COCO-
NOT AND THE DETERIORA-
TION OF ITS PRODUCTS.
ABSTRACT BY C. DRIEBERG.
The latest issue of the Philippine
Journal of Science contains a series of
notes on the sprouting of the coconut,
on copra and on coconut-oil, which
ought to prove of interest to the planter.
The first of these notes treats of
experiments made witha view to discover
if the coconut, like the castor-oil bean
and many other oil seeds, contains a
fat-splitting enzyme capable of saponify-
ing outside of the growing nut.
A large number of tests were carried
out, the details of which it would hardly
prove of interest to traverse, but the
result of seven months’ work in this
connection was tothe effect that there
was not the slightest proof of the
existence of such an enzyme. The
cause of the destruction of the fat
which takes place in the growing nut
has, therefore, to be sought for else-
where.
The second note deals with the changes
accompanying the sprouting of the nut.
As regards the milk—or, as we eall
it, the ‘‘ water ”—(for coconut milk is,
with us, the expressed milky juice of
the meat or flesh) the total quantity
showed a marked diminution from 374
grammes in an unsprouted nut to noth-
ing when the sprouts had attained a
height of 93 centimetres. At the same
time there is a decided loss of sugar,
which falls from 2% and 2°3% in the
milk of unsprouted nuts to 8% in that
of the nuts with sprouts 88 centimetres
in height. In the meat or flesh a
definite loss in total weight is evident,
since it drops from 475 grammes in the
unsprouted nut to 148in the nut with
sprouts 93 centimetres high. The loss
appears to be due to direct absorption
by the foot, the process taking place at
first only in the portion of the meat
near the latter, but increasing rapidly
as the endosperm grows larger and
comes in contact with the entire inner
surface of the nut.
The loss in weight of oil is fairly propor-
tional to the loss in weight of meat, the
percentage of oil in the meat remaining
constant within the somewhat wide
limits of individual variation. During
the early stages of germination there
is apparent a certain concentration of
oil near the foot, with corresponding
loss in that portion of the meat farthest
away.
Water is gradually lost by the meat, as
well as all other parts of the nut, by
evaporation through the shell and sprout
during germination. The percentage of
sugar decreases from 4% % in the
unsprouted nut to 1:12 % in that with
a sprout 938 centimetres long.. The loss
is probably to be attributed to absorp-
tion of sugar by the foot, as in all
cases there is considerably less sugar
in that portion of the nut in direct
contact with the endosperm than there
is in the parts farthest away from it.
As regards crude fibre in meat no
decided change in the proportion can
beobserved. Itis absorbed at practically
the same rate as the rest of the meat.
In the observations regarding the
changes taking place in the foot, it was
found that the total weight increased
from 19 grammes in the unsprouted nut
to 228 grammes in those with a sprout 93
centimetres high. There was apparently
also a loss in the percentage of sugar
(although not in its total weight) until
the foot completely filled the nut, at
which time there is rapid gain. This
phenomenon is probably to be attributed
to the fact that the foot at first draws
its sugar chiefly from the milk, by which
it is almost entirely summoned. How-
ever, as it continues to grow, it soon
exhausts the sugar in the milk, and
only when it has completely filled the
nut and come into intimate contact
with the inner surface of the meat, has
it an opportunity to continue the
process:of sugar absorption and also
of sugar creation, possibly from the
oil, or possibly from oil and erude fibre.
Ot crude tibre there was only a slight .
increase to be noted.
From the commencement of the ger-
minating process oil from the meat near-
est the foot is invaiably richest in fatty
acids, and this difference becomes more
marked as germination proceeds. It is
only when the foot has come in complete
contact with the meat that an increase
in fatty acids throughout the whole
nut is observed, indicating that oil, to —
be in a condition for absorption, must
be hydrolised. This hydrolysis may

take place as the result of an enzyme
in the foot, or be caused by one in
the meat, which is dormant until
rendered active by some product of
metabolium in the foot. It is, however,
not possible to prove by an _ increase
in free fatty acid the presence of any
fat-splitting enzyme in the coconut.
Such an enzyme may exist, but under
such conditions that any large excess
of free acid must be used up by the
growing plant before the process can
continue.
To summarize ina word the changes,
determinable by chemical analysis, in
the growing coconut :—
Oil is lost by the meat; it is not
taken up as such by any other portion
of the nut, but is either oxidised to
furnish energy for the growing plant,
or is split up and transformed by
progressive synthesis into sugar and
finally into cellulose. Sugar is lost by
meatand milk, but a corresponding
quantity is gained by the foot, the
total quantity in the nut remaining
approximately the same. Asmall amount
of crude fibre is lost by the meat, but
a much larger quantity is produced in
the sprouts and roots.
Note 3 deals with the action on copra
of micro-organism in pure culture.
The Philippine Journal in 1906 recorded
the fact that moist copra is attacked
by micro-organisms with consequent
splitting up and destruction of the oil
—this action being most pronounced
when the copra contains from 10 to 15
per cent. water. Under these conditions
the growth of mould predominated
largely over that of the bacteria. With
a much larger percentage of water, and
when the bacteria were in excess of the
moulds, the destruction of fat is greatly
diminished. These observations led
logieally to the conclusion that hydro-
lysis of oil in copra was due to mould
action alone, although the then available
data did not exclude the possibility of
symbiosis and interdependence, in this
fat-splitting process, between moulds
and bacteria. Dr. Edwards of the
Biological Laboratory of the Philippine
Bureau of Science, in pursuing further
research into this question, separated
some fifteen different organisms from
mouldy copra and coconut meat, and
finally succeeded in isolating in pure cul-
tures the majority of the growths
present. The identification of every
organism was found to be impossible, and
indeed the majority of them are probably
new and undescribed. However, the
main object of the experiment, viz., the
differentiation between moulds and
bacterial action has been accomplished.
11
Oils and Fats.
Taking the total weight of dry copra,
every active mould culture brought
about a decided loss ranging from 5 to
11 per cent., while only one bacterium
was found to cause any appreciable loss,
The moulds destroy a certain percent-
age of the oil, and the greater portion of
the loss is attributable to this cause.
These losses, which represent 8-9 to 19:9
per cent. of the original weight of oil,
are accompanied by hydrolysis with the
formation of fatty acids and glycerine.
There seems to be no direct relation
between the percentage of free fatty
acid evolved and the total quantity
of oil destroyed at the time, since low
as well as high precentages of free
acid show the same loss of oil. As
already mentioned, only one bacterium
caused diminution of oil, and this only
to the extent of 4 grammes, which is
less than that brought about by the
mould with the weakest action, and
the loss isnot accompanied by hydrolysis
in this case, On the other hand, one
bacterium appears to have caused a
slight gain in total oil. The sugar is
almost completely destroyed by all
moulds, whereas bacteria may be said
to produce no effect here.
Looking at this matter from a com-
mercial standpoint, it may be stated that
mouldy copra must have suffered a loss
in total oil-content which may reach the
neighbourhood of 20% under the most
favourable conditions, but certainly to
an extent to be taken into account in the
purchase of such copra. Such inferior
produce undoubtedly cannot give as good
a yield of oil as that which has been
carefully dried and preserved. On the
other hand, in the case of badly cured
copra, if a sufficient quantity of water
(about 15 %) is present, it is bacterial
action and not mould action that will
come into play ; so that no diminution of
oil would be observed, though bacteria
so disintegrate and change the copra
thataslimy soft mass characterised by an
objectionable odour, and difficult to work
so as to procure pure oil reasonably free
from acid, results.
In the Philippines a large amount of
copra is dried by means of fires in pits,
the meat being placed on bamboo
gratings above and the fuel beneath. It
is not impossible that the smoking
to which the copra is subjected has a
slight antiseptic action which would
tend to diminish the subsequent growth
of oi1ganisms, and so to preserve the oil.
Nevertheless, the arguments are all in
favour of a clean white, prefectly dried
copra, which will not afford a medium
for the growth of organisms, unless the
Oils and Fats.
Conditions of shipping it are such as to
allow of sufficient absorption of water to
acilitate mould growth.
To summarise this part of the paper :—
Six ditferent moulds, any one of which is
capable of hydrolysing and destroying
fat, have been isolated from the many
organisms growing on rancid copra.
This fat-destruction is part of the life
process of the mould, and is independent
of bacterial action.
Copra acted on by moulds was found
to have suffered an almost total loss of
sugar. The bacteria found on copra
have very little effect on the quality or
quantity of oil produced. Their effect
is practically to produce _a more or less
sour odour and bring about disintegra-
tion of the meat.
It is good commercial practice to
prepare only the best, white, and per-
fectly-dried copra.
The fourth and last note deals with
the production of freeacid in commercial
coconut oil on long standing. Thirty-
five samples of oil of various conditions
were examined, and the table of results
provided show the percentage of free
fatty acids (as oleic) at the start, and
after two months, four months, six
months, one year and three years.
The conclusion to be drawn may be
stated as follows :—The deterioration of
afreshly prepared commercial coconut
oil is produced by at least three entirely
independent processes, and may _ be
divided into two distinct periods of time.
The first, rapid splitting up of the fat,
beginning immediately afterits expres-
sion from copra and continuing for several
months up toa year or more according

to the nutritive matter present, is
occasioned by moulds which are either
pressed out with the oil together with
sufficient sugars and albuminoids for
their growth, or, in the case of hot
pressed oils, enter the freshly prepared
oil from the air. This action continues
as long as sufficient nutritive material
for mould growth remains in the oil. It
may be completely checked by filtration,
preferably after heating to 100° C. more
thoroughly to coagulate albuminoids and
to destroy any enzymes already secreted
by the moulds.
Toward the end of this first period,
oxidation by the air sets in and may
continue indefinitely. The rate of this
process depends upon the amount of
surface exposed to the air, compared
with the total volume of oil, and may in
extreme cases cause an exceedingly rapid
deterioration. It may be entirely pre-
vented by storing the oil in completely
tilled receptacles impervious to air.
Along with the two above-mentioned
processes, a slight hydrolysis, due to heat,
moisture and free acids already present,
is constantly taking place.
reduced considerably by filtration, which
removes most of the water, together
with the organic impurities,
There is reason to believe that some
hydrolysis is brought about by enzymes
produced by the moulds, as unheated oils
which have been filtered and rendered
antiseptic increase in acidity somewhat
more rapidly than do heated ones under
the same conditions. However, this dis-
tinction is not so apparent after the
first year.
Light has apparently no effect on the
oxidation by air of coconut oil.

DYES AND TANS.
THE USE OF TERMINALIA ARJUNA
BARK FOR TANNING.
By D, O. Wirt, 1F.s.
Until lecame tothe Nimar division of
the C. P., the use of the bark of Terini-
nalia Arjuna (Kohar) as a_ tanning
material was unknown to me.
That its use is far from general may be
gathered from the fact that no mention
of itis made in Watt’s Dictionary of
Economic Products, Vol. VI, Part t, page
16, nor in Brandis’ Forest Flora of the
North-West and Central India, p. 225,
though both authorities mention the
bark as used medicinally.
Its use would, therefore, seem tobe very
restricted and hence of little importance,
and in ealling attention to it, it is
more with a view to point out a parti-
cular form of damage that may be caused
to our forests by its use than to assist in
turther developing the industry. I will
first give a briet sketch of the industry
and the methods employed in the use of
the bark. It is extensively used by
chamars in the Nimar District for the
tanning of hides, and especially by the
shoe-makers of Burhanpur, a fairly large
community, where its use first came to
my notice.
Removal and Collection of the Bark.—
The bark is stripped from the trunk and
main branches during the months of
- Aprilto June. The period of the year
is an important point to which I shall
reter later. This time of year is chosen
as the sap is then most activein the
cambium layer and the bark separates
more readily from the wood than when
the flow of sap is at its lowest. I need
hardly add the collectors strip off the
entire bark, and are not in the least con-
cerned with the immediate resuit, viz.,
the death of the tree,
Treatment of the Bark.—The bark is
then dried in the sun and pounded with
mallets until reduced to shreds oras fine
a consistency as possible. No further
treatment is necessary. It is now ready
for use, and is caretully stored away
until required, great care being taken
not to expose it to rain or damp.
Process of Tanning.—l. Lime Treat-
ment.—A fresh hide being taken, the
inner side is well rubbed in with lime,
tightly folded up, the inner side inside,
and immersed in water contained in a
broad-mouthed earthern pot or ‘“‘nand”
for ten to twelve days, the hide being
kept pressed down with a heavy weight.
During this period it is taken out every
third or fourth day, well shaken, and
again rubbed in with lime and put back
in the ‘‘nand.” About three seers of
lime are rubbed into an average sized
hide on each occasion. As many as four
hides can be treated at the same time in
this way. In place of the “‘nand” a pit
two feet by two and half feet is some-
times dug in the ground for the same
purpose. When the above process is
complete the hide is taken out, well
kneaded with the hands aad the lime
washed off with cold water. All shreds
of meat that remain attached to the
inner side are carefully removed with
an instrument know as a ‘‘ rapi,” while
the hair remaining attached to the skin
is removed by scraping with a blunt iron
blade (kulpi) worked with both hands.
It is then once more washed with cold
water.
2. Dyeing.—The next stepis to give
the hide the requisite colour. This is
done by the aid of one or two dyeing
materials, viz., the young leaves of
Anogeissus latifolia (dhaura), of the
mature leaves and twigs of Phyllanthus
emblica (aonla). The leaves of the
‘‘dhaura” are collected in the month of
May when they are young and tender,
and after being dried in the sun and
pounded are ready for use. The
*‘aonla” leaves and shoots, on the other
hand, are collected in November and
December when they are mature
and tough. About four seers of the
powdered ‘‘dhaura” or ‘‘aonla” leaves
are put into a “‘nand” with cold water
and well stirred in this solution, the
hide now immersed and left for from
6 to 8 hours. It is then taken out,
wrung dry, and again immersed in a
fresh solution. This process is continued
every two or three days until the hide
has assumed the required colour vary-
ing froma pale yellow toa light brown.
The length of time required to give the
requisite colour may be from three to
nine days, according to circumstances,
Sometimes both ‘dhaura” and ‘aonla”
leaf solutions are used alternately.
3. Tanning.—The colour process being
completed the hide is ncw ready to
be tanned. Theedgesof the hide are
brought together and stitched so as to
form a sort of bhisti’s “mashak” cap-
able of holding liquid, and termed
‘“‘adhurhi.” It is then slung up to a
post or tree and filled with water. Into
this water is now thrown from 20 to 30
seers of the prepared Kohar bark. An
-
Dyes and Tans. 14
earthen vessel is placed underneath to
catch any liquid that may leak out,
which liquid is from time to time poured
back into the improvised “‘ mashak,” thus
keeping it. continually filled up. The
object of this is to subject the entire
skin to the action of the tanniag mate-
rial held within in solution. The skin
remains thus for two days, and on the
third day it is inverted and left for
another three days in this new position,
while still fuli of the solution. In six
days the process is complete, the solu-
tion is drained off, the stitches holding
the sides together are cut away, and the
skin now converted into leather; after
being dried in the sun it is ready for use.
The above is a description of the
ordinary process employed. It may,
however, be varied by mixing with the
Kohar bark ‘‘dhaura” and ‘‘aonla”
leaves in the proportion of two of bark
to one of leaves.
Source of Supply of the Raw Materials’
—Having now described the process of
using the bark, I turn to the question of
the raw material from the forests or
wherever it may be available. The first
point to draw attention to is the loca-
lity in which the Kohar tree (Terminalia
Arjuna) is almost always found. In the
C, P., I think, it is safe to say that 95 per
cent. of the Kohar trees are to be found
growing if not actually on the very bank
of perennial streams and annual water-
courses with half their root system
exposed in the bed of the streams, yet
seldom if.ever more than 20 feet from
the edges of such streams. This pecu-
larity of the tree is very marked. How-
ever rich and moist the soil you will
not find a Kohar tree, in this part of the
country at any rate, far removed from
a stream. The result as might be
expected is that whether in forest or
in open cultivated land, wherever a
perennial stream flows or a stream that
keeps pools of water in it here and there
throughout the hot weather, the greater
proportion of trees, say 75 per cent.
growing along such streams, are Kohar
trees. Itfollows then that all thesupplies
of this bark must be obtained from trees
erowing along the banks of streams and
water-courses. As previously stated,
the collectors of the bark are quite indif-
ferent to the effect of their actions on
the trees themselves, with the inevitable
result that considerable numbers of
Kohar trees are killed annually to sup-
ply the chamars with the bark they
require for their tanning process. The
death of these trees is further hastened
by the period of the year chosen to
remove the bark, z.e., from April to June,
when the hot scorching winds blowing
at the season effectually debar the
| JANUARY, 1909,
damaged trees from any chance of re-
covery. What is therefore happening
is that streams and water-courses are
rapidly being denuded of the tree
growth growing along their banks.
Influence of Tree Growth on Conserving
Water supply.—Now a great deal has
been written lately in the Indian
Forester and elsewhere on the subject
of the influence of forests on water
supply and rainfall, and not without
reason.
I would specially mention ‘‘ Notes on
the Influence of Forest on the Storage
and Regulation of the Water Supply ”
by Mr. S. Eardley-Wilmot, Inspector-
General of Forests. (Forest Bulletin,
No.9.) Not the least important point in
this intensely interesting question is the
influence of the growth in maintainiug
an equable flow of water inthe streams
and keeping up the ‘‘ spring level” of
the water in the subsoil. It is unneces-
sary to go into the arguments and
reasons in support of these facts, they
will be found fully explained in the
literature referred to above, but they
are incontestible facts. To put it
shortly, by preserving the tree growth
along the banks of streams you (1)
mitigate the violence of the rush
of water in the streams during the
rainy season, (2) prevent erosion
of the banks, (8) maintain a more
equable flow of water in the stream, and ~
thereby (4) tend to lengthen out the
period of flow, (5) assist in keeping the
water in the subsoil at a higher tevel.
Conversely by destroying the tree
growth along these trees you obtain the
very opposite effect. That this effect is
baneful in itself goes without saying,
but, and I wish to emphasize this point,
it is particularly harmful in the region
to which I am referring.
Liability to Scarcity of Water in
Regions where most Damage is done to
Kohar trees.—In the Nimar district the
rainfall is very scanty averaging about
30 inches, but varying from as little as
18 in. to over 50 in. The district is
therefore peculiarly liable to scarcity
of water. Now, the tract where most
damage is done to the Kohar trees
consists of hills of trap with the very
poorest soil covering, large stretches of
sheet rock being frequent. The tree
growth on these hills is of the scantiest,
consisting entirely of very open Salai
(Boswellia serrata) forest. Along the
base of these hills stretches a broad rich ~
valley intersected by streams and water-
courses fed by the rain of these hills. It
is not so long ago that most of this valley
was under forest. Now, it is all given
up to cotton cultivation, and practically
Rah
JANUARY, 1909. ]
the only trees left in it are such as have
survived along the banks of the streams.
Here the destruction of Kohar trees is
going on apace. From the nature of
the soil covering and tree growth on
these hills it is clear that during the
monsoon the proportion of rain running
off and not absorbed, will be much
greater than from more favourably con-
stituted forests as regards soil covering
and tree growth, while the rush of
water in the streams at any particular
moment of heavy rainfall will also be
greater. Under these circumstances the
value of the existing tree growth along
the streams in the valley is considerably
enhanced, and it behoves us’'to maintain
at all costs the maximum of such tree
growth.
Quantity of Bark used annually in
Nimar.—It is estimated that about
4,250 mds. of Kohar bark are annually
usedinthe Nimar district for tanning
purposes,
An actual experiment made to ascer-
tain the quantity of bark obtained from
a mature and average sized Kohar tree
showed the green weight of the bark
removed to be 47 seers. The weight of
this after drying was 21 seers.
A reference to the ‘‘ Process of Tanning”
will show, then, that the bark of one
tree is not quite sufficient to tan one
average-sized hide.
Taking halfamaund (20 seers) as the
average quantity of dry bark obtained
from one tree, and the total quantity of
dry bark used in the district in one year
as 4,250 maunds, we arrive at the con-
clusion that no less than 8,500 Kohar
trees are annually stripped of their
bark, and, as all this bark comes from
Malguzari and Ryotwari areas, the
damage done must be very extensive
even after making allowance for such
trees as recover from the treatment
they are subjected to.
Necessity for Kestricting the Removal
of Kohar Bark.—Hither then the absolute
prohibition of the barking of Kohar
trees should be enforced or ‘steps taken
to reduce the damage done to the trees
toa minimum, In Government forests
extraction of the bark is entirely for-
bidden, but it is chiefly in the Malguzari
and Ryotwari areas that the mischief is
greatest. Undec the rulesapplicable to
waste areas in Malguzari villages, the
felling of any tree growth within 20
yards of a stream in which water
ordinarily remains till the month of
January is prohibited. There is nothing,
however, in the rules forbidding the
barking of trees with its inevitable
result the speedy death of the tree.
Dyes and Tans.
Orders have lately been issued by the
Deputy Commissioner enjoining on all
Malguzars the importance of maintain-
ing, as far as possible, a permanent tree
growth along streams and pointing out
the damage done by the barking of
Kohar trees, and recommending that at
least one-third of the bark on any
Kohar tree should be lett when barking
the trees. It is questionable, however,
whether the recommendation will be
acted up to. It, would therefore be
preferabie to absolutely forbid the
removal of Kohar bark, and the chief
point in favour of this prohibition is that
the use of Kohar bark is not absolutely
indispensable to the preparation of
leather.
Substitutes for Kohar Bark.—From
enquiries made it has been ascertained
that the tanning process can be carried
out with the use of ‘‘dhaura” and
‘““aonla” leaves only, and in certain
parts of the district Kohar bark is sel-
dom, if ever, used. It is said that Kohar
bark used by itself produces a hard
leather, and that therefore leaves of
“dhaura” and ‘‘aonla” are mixed with
it. The bark of Saj (Ternunalia tomen-
tosa) is sometimes used in place of Kohar
bark, but there are difficulties in its,
removal from the treeand hence it is not
much in favour. The fruit of Ghatbor
(Zizyphus Xylopyrus) is also frequently
made use of. It would appear that the
use of Kohar bark is more a matter
of habit than necessity. The chamars
of Burhanpur tried very hard to get
a reversal of the decision that no bark
was to be extracted from Government
forests, stating that their industry de-
pended on the supply of this bark. Just
about this time I had come across a
number of bushes of Awli (Cassia
auriculala), growing on waste land
round the town. This species, as is
well known, provides one of the best
tanning materials and is largely used
in the Madras Presidency, yet when
asked aboutit the chamars of Burhanpur
stated that they had never used it and
did not even know of its value as a
tanning agent.
Cassia auriculata will grow equally
well on dry stony soil and on _ black
cotton soil, and there seems no adequate
reason why it should not be grown in
sufficient quantities to supply the
chamars of Burhanpur with all the
tanning material they require. There
are several waste patches within the
municipal limits which are eminently
suitable for the growth C. auriculata,
and, which, if planted, or sown up and
properly managed, would in a very
short time become a valuable source

of revenue to the Municipality, besides
supplying a cheap and excellent tanning
material at the very doorsof the chamars
who require it. The first crop of bark is
obtainable when the shrub is five years
old, so that: the initial cost of cultiva-
tion is by no means prohibitive.
Then, again, there is Acacia arabica
(Babul) the bark of which furnishes
an excellent tanning material. The
Babul grows particularly well on black
cotton soil, and as the valley at the
entrance of which Burhanpur is situated,
consists almost entirely of this soil,
there would be no difficulty in growing
this species. Tenants and ryots might
be induced to plant their field bound-
aries and hedges with Babul, and would
always be sure of finding a market for
the bark.
Cost of the Bark.—The chamars, as a
rule, extract their own bark obtaining
licenses from the Malguzars at the rate
of Rs.3 to 4 per ecart-load of dried
bark. This means an average royalty
of 8 annas per maund.
Reasons for the Use of Kohar Bark.—
The real explanation of the use of Kohar
bark is that it is easy of extraction
‘and has been obtainable in abundance,
and the idea of any restrictions ona
custom of long standing is of course
repugnant to the ideas of any native.

INDIAN WATTLE BARK.
‘“Wattle Bark” is the general name
applied, both in commerce and the arts,
to the barks of the various species of
Acacia exploited within the tropics and
elsewhere for the tannin which they
contain. Over thearid sandy wastes that
occur throughout the torrid regions of
the globe, the thorny acacias instal them-
selves on the banks and beds of rivers
and streams and shallow depressions
such as admit of the temporary lodge-
ment of water during rain. In some
situations during seasons of flood, they
are frequently completely submerged for
days, but recovering themselves from the
depressing effects of the transitory deluge
with seeming impunity, they flourish
through the drier months of the year
under conditions of climate untenable to
all but very few species of broad-leaved
trees. Indeed the rigors of climate to
which the zones that constitute the
habitat of the acacias are subjected, may
be gauged from the fact that some of the
species are unable to develop ordinary
leaves. The phyllodes, which take the
place of the latter, are suitable modifi-
cations of the stem equipped to perform
all the functions of the leaves they
substitute. Although the foliar organs
of most of the acacias are usually small
and seemingly delicate, the profusion in
which they ‘occur in the plant, their
remarkable phyllotaxis or arrangement,
and their incessant and vigorous activity
throughout long and arduous periods of
vegetation result in the formation, among
the rest, of comparatively dense cortical
layers surcharged with a variety of
valuable substances of which the most
important is tannin. When it is re-
membered that the tropical acacias form
a large and well distributed group of
plants, it will be realized that the
availability of tannin from this source
alone is great indeed. Nevertheless, it is
a notorious fact that only a few ‘species
of the genus are exploited for the
extraction of tannin. In India, again,
with about eighteen species that are
indigenous to the warmer parts of the
country,
(Willd., and Acacia catechu, Willd.,) are
the only ones at present employed to any
extent in the art of the tanner.. More-
over, it must be further conceded that,
so far from making the least attempt to
commercially exploit the bark of th,
indigenous acacias. we have permitteq
ourselves, at considerable expense, t
introduce four, and experiment with two
of the so-called wattle bark trees of’
Australia. Introduced on the Nilgiri
hills of Southern India in the early
forties of the last century, these in-
teresting and valuable exotic acacias
required no less than a period of thirty
long years to become acclimatized and
completely naturalized. And even
though as doubtless they do, the black
and silver wattles of Australia (Acacia
decurrens, Willd., and Acacia dealbata,
Link.) yield relatively large quantities
of tannin of a quality which is inferior to
none, not only in India but wherever
else the factors of soil and climate have
been found to adequately suit their
several requirements, their adaptability
and general
alone are circumstances which are un-
worthy to be advanced against the
serious consideration of the neglect to
which the local species have been now
and always consigned.

JANUARY, 1909.]
In endeavouring to invite public at-
tention to the immense possibilities that
lie in the direction of the systematic
exploitation of some of the commoner
Indian acacias as sources of tannin, it
must be mentioned that the mocerate-
sized, diffuse-branching, gregarious
species, botanically known as the Acacia
arabica, is certainly one of the most
neglected but valuable. Although the
quality of the bark of this acacia is
inferior to that of the Australian wattle
and even to that of the Acacia catechu,
the extent of distribution of the species
in India and the numbers in which they
occur there are such as to warrant the
eonelusion that its systematic exploit-
ation for tannin-extraction is likely to
meet with favourable results by retriev-
ing in quantity whatit cannot in quality.
The natural regeneration of the tree
being easy but somewhat slow from seed,
its artificial reproduction, for ecouomic
purposes, could be more successfully
accomplished by the creation and
development of shoots and suckers from
the stool. For this the tree requires to be
coppiced at suitable intervals, from
time to time. The safest period, con-
sistent with utility, of the economic
exploitability of the species, is said, on
good authority, to be ten years,—
the age at which the. bark has been
found to be mature enough to contain
tannin of sound and serviceable quality.
At this age, too, the possibility is
greater than at any other recently
anterior one of obtaining an appreciable
quantity (half a ton) of bark from each
tree, that will have been coppiced.
With the yield of tannin at 15 per cent.
‘actual experiment giving 18°95) a tree
would produce 168 pounds of the sub-
stance at the close of the tenth year of
its age. Thereafter, the yield, which
improves with coppicing, would directly
depend on the number, size, and vigour
of the shoots which would be permitted
to develop on the stool from those given
out after each periodic felling, As
regards the other Indian acacias, in-
formation of a reliable nature relating
to the yield of tannin from the bark is
at present unavailable. The important
Khair (Acacia catechu) itself is seldom
looked upon as a source of tannin,
outside the great and well known
capacity of its wood as a yielder of
catechu or catechu-tannin (catechin),
No endeavour, beyond the local and,
therefore, comparatively limited appli-
cation of its bark as a tanning material, —
has as yet been made in India. To
obtain the catechu the tree is felled and
its heartwood cut up into chips and
boiled. The bark, however, with its
stores of tannin, is usually left to rot on
3
17 Dyes and Tans
the ground. Some idea of the extent to
which this wastage of a useful and
valuable raw material now takes place
in the country may be gained from the
fact that throughout the wide area of
its distribution thousands of trees are
annually felled. Why, when the wood
is being boiled for catechu, or otherwise
utilized throughout the country, the
bark is not at the same time treated for
the manufacture of an extract which
assuredly contains a high percentage of
tannin of good quality is a question
which so far appears to have been pro-
vocative of no reasonable or satisfactory
response. The fact, at any rate, seems
to savour of some of that sublimely
supine indifference which the son of the
soil has been proverbial for displaying
in treatment of great and glorious
heritage—a mine of wealth whose super-
ficial veins themselves still largely wait
upon his consideration.
Besides the two indigenous acacias
deseribed above as sources of tannin,
the undermentioned Indian species, too,
deserve our best attention in India :—
(1) Acacia Farnesiana, Willd.—A low
erect shrub or small tree occurring
throughout the plains of India and
Burma; it has bright yellow flowers
that are fragrant and arranged in the
axils of the leaves; it isarmed with long
straight spines.
(2) Acacia ferruginea, D. C.—A large
deciduous tree with reddish brown
bark; armed with short, hooked, double
spines, the flowers occurring in axillary
peduncled spikes.
(8) Acacia jacquemontu, Benth.--A
small elegant bushy shrub with smooth
stem and straight, slender, shining
spines; flowers like those of (1).
(4) Acacia Latronum, Willd.—A small
tree or shrub of Southern India, occur-
ring in gregarious thickets; its flowers
are given out in numerous spikes from
the nodes of the branchlets when the
tree is leafless and double spines are
long and straight.
(5) Acacia planifrons, W. and A.—A
species similar to (4) in habit and dis-
tribtuion but with grey lenticels in
place of spines. (4)and (5) form fiattened
tops that are very conspicuous and
remarkably typical of the dry open
forests in which they occur.
(6) Acacia leuwcophica, Willd.—A large
deciduous tree with short, straight,
white spines, flowers in small heads
borne on long terminal tomentose
‘panicles.

tree with short, hooked, double spines
and small sparse, greenish yellow spikes
of fiowers.

THE INDIAN COTTON CROP.
The following first general Memoran-
dum on the Cotton Crop of the season
1908-09 has been issued by the Commer-
cial Intelligence Department, India.
The provinces dealt with in this memo-
randum represent, on the average of the
five years ending 1906-07 a total of
15,007,700 acres under cotton, this being
equal to 76 per cent. of the entire
reported cotton area of India. The
memorandum relates, however, mainly
to the early crop and records acreage
only.
The total area at present reported is
11,118,000 acres against 11,255,000 acres
(revised figures) at the same date last
year. There is, therefore, a net decline
of 1°38 per cent,
Noattemptis madeat this season to
estimate the probable outturn; but. the
present condition of the crop is reported
to be generally good or fair, except in
parts of Bombay and Burma.

DRUGS.
QUININE IN INDIA.
Quinine has become in the Indian
mind the type and chief of Western
drugs, says the Resolution upon the
triennial report on the working of chari-
table dispensaries in the Punjab. Mala-
ria here as elsewhere is the chief
scourge, and, with the habitual resort
to quinine, the Indian has come to feel
that it is on this that hospital treatment
must rely. The result is that when the
supply of quinine proves inadequate,
as is often the case, there is disappoint-
ment, as though no other treatment
could be effectual, and doubtless the
growing confidence in hospital treat-
ment receives some check. One remark-
able feature of outdoor medical relief is
disclosed in the report, that is the num-
ber of patients who did not see the
doctor themselves but were represented
by friends. This system so far from
waning seems to grow, for in this case no
fewer than 230,475 sufferers underwent
‘‘absent treatment.” The proportion of
those so dealt with varies so greatly in
different districts as to suggest that
tactful methods might effect some im-
provements.—Indian Agriculturist, Vol.

EDIBLE PRODUCTS.
POTENTIALITIES OF PLANTAIN
MEAL.
One of the greatest drawbacks to the
economic development of India is that
most of her potential industries are
permitted to lie dormant till such time
as foreign capital may happen to be
introduced to work them. It is not
because there is not sufficient capital
in the country, but because the owners
prefer to hoard or invest it in securities
that cannot yield anything like the
return a well-managed industry would
be likely to do. To some extent this
lack of enterprise is due to ignorance
as to what industries hitherto unex-
ploited would be likely to turn out
profitable, but it is more frequently
attributable to lack of initiative and
disinclination to assume the role of
the pioneer. From time to time we
have drawn attention to what we believe
to be suitable openings for Indian trade;
and, amongst other minor industries,
to the manufacture of banana or plan-
tain meal. The flour of the plantain,
under the name of “Bananine” and
‘‘Banaharina” has been manufactured
for several years in Central America
and the West Indies, It is produced
from partly ripe fruit by removing the
skins, drying the edible portion and
reducing it to powder ina grinding
machine. The average weight of fruit
required to produce 1 ewt. of flour is
5 cwt., that is a yield of 20 per cent.
In the Indian Trade Journal of January
17th we mentioned that a company had
been started in London to manufacture
banana flour for bread, banana oats
for porridge, banana custard powder,
banana cocoa, banana cake and pastry
flour, banana blane mange powder,
banana jelly powder, banana health
salts, ete., and it may have struck
readers as curious that capital should
be forthcoming for such a purpose in
a country where the fruit does not
grow, while in India, where the cultiva-
tion of the plantain is universal, enter-
prise of this kind on any considerable
scale is practically non-existent. There
may or may not be good reason for
this; but the fact remains that for
years past the health-giving and sustain-
ing properties of banana meal have
been known not only in civilized coun-
tries, but also amongst the natives of
South Africa, and presumably there is
room for it in the list of the world’s
edible products. The late Sir H. M.
Stanley, during his equatorial travels,
was so struck with the value of this
product, that he expressed the opinion
that, if only its virtues were publicly
known, it would be largely consumed
in Kurope, especially by children and
persons of delicate digestion.
There are a few scattered concerns
in India, eg., at Saharanpur, where
plantain meal is manufactured in a
small way, but practically nothing seems
to have been done to produce it ona
large scale, and with such machinery
as will turn it out in commercial
quantities at the lowest possible cost.
A European firm at Calicut, which has
lately been examining the possibilities
of this industry, has favoured us with
asample of banana meal prepared by it.
This sample Mr. Hooper, of the Indian
Museum, has very kindly analysed for
us with the following result :—

Albuminoids 3'31
Carbohydrates 81:29
Fibre ae ms a 90
Ash Mac ys 2°60

‘“This analysis discloses,” says Mr.
Hooper, ‘‘a starchy food with a small
amount of nitrogen and very little
fibrous matter. It is quite free from
tannin, which is found in some samples
as banana flour, and should be very
digestible. Its composition is similar to
that of the flour made from bananas in
America, as the analyses of samples from
Jamaica and Venezuela will show :—

“The Calicut product, it will be seen,
compares very favourably with other
meals in containing no tannin. Banana
meal as an article of food, according to
its analysis, occupies an intermediate
position between the cereal flowers and
arrowroot starches which should recom-
mend it especially for infants and
jnvalids.”
In Venezuela, we believe, the retail
price is about 5as. for 1 lb. packages,
but in Caleutta the retail price for the
same weight of plantain flour is rather
high, viz., Re.1; but if more attention
JANUARY, 1909.]
were given to its manufacture, no doubt
it could be produced locally at a more
reasonable cost. It is believed that
Rs. 360 per ton represents the average
cost of production in Saharanpur, in
Bengal, and Anuradhapura in Ceylon;
and for foreignmarkets the cost of pack-
ing, freight and shipping charges have to
be addedtothis figure, say another Rs. 20
per ton. The total cost should not ex-
ceed Rs. 380 per ton orjust under 3 as.
per lb., while the retail price in Caleutta
works out at Rs. 2,240 per ton, leaving a
margin of profit of Rs. 1,860 per ton or
nearly 500 per cent. The wholesale
price in Calcutta is not ascertainable,
but even if itis as low as Rs. 600it would
leave a handsome margin of profit. In
small markets, of course, an insignificant
increase of supplies has avery adverse
effect on prices, and it has been pointed
outtous that banana flour has been
placed on the London market at £20 or
Rs, 300 per ton (which is less than the
cost of production in India), and even
then it was doubted whether this price
could be maintained in the face of a
laige consignment. This is discouraging
for manutacturers in India, for they
must look for profit in the beginning to
their export trade, at any rate until an
indigenous demand has been created.
Plantain flour, of course, cannnot hope
tocompete with farinaceous materials
selling in London at £6—£12 per ton,
but that is no reason why it should not
come to be recognised and appreciated
as a dietetic luxury ; and if so, its price
should be regulated not by that of
wheat and rice flour and potato meal of
a low nutrient value, but by that of
superior products which command a
more restricted but yetanample market.
Upon this factor the establishment of
the plantain meal industry in India on a
scale commercially profitable would
seem to depend.
FRENCH EXPERIMENTS,
It has been found from a series of
experiments in French Guinea that an
efficient and cheap way of manufac-
turing plantain meal is simply to peal
the bananas and dry themin the sun.
The meal thus obtained is of excellent
commercial quality. It is obvious,
however, that this procedure can only
be followed in tropical countries, so that
an apparatus which permits of desicca-
tion at any time is often necessary when
business is to be conducted on a large
scale. The principle on which these
desiccators are constructed is very
simple. Allthatis required is to circu-
late hot air over the fruit to be dried.
The apparatus consists of a furnace, in
which any kind of fuel may be used, and
a box arrangement in which are super-
Hdible Products.
imposed a number of trays of metallic
net work through which the hot air
from the furnace, freed from the gases
of combusition, passes and dries the
fruit. The trays containing the fresh
plantains are placed in at the top of the
apparatus and taken out at the bottom.
he prices of such desiccators vary
roughly from Rs. 800 to Rs. 750. Illus-
trations of two such machines may be
seen at this office.
Further experiments carried out in
French Guinea go to show that a hun-
dred kilo (kilo, 2,204 lbs.) of bananas in
bunches as plucked yield 65 kilos of
peeled bananas, and these 62 kilos,
treated in the machines mentioned, give
about 19°5 kilos of plantain meal, Much,
however, depends upon the method of
desiccation. When the process is pro-
longed in order to obtain a golden colour
for commercial purposes the yield may
be aslowas 14°32 kilos; and dried too
fast not only is the weight seriously
reduced, but the fruit becomes carmel-
ised and depreciated in value. It will
be seen that the yield of plantain flour
under ordinary conditions, is roughly
20 per cent., which agrees with Mr.
Hooper’s estimate published in our
issue of July 16, p. 62, that the average
weight of fruit required to produce
1 ewt. of flour is 5 cwt. It has also
been ascertained in the course of
the French experiments that although
unripe and partially ripe bananas may
be converted more quickly into meal,
ripe bananas which contain more sugar
give the best results.
In a previous article on the subject
we stated that the manufacture of plan-
tain meal was being taken in hand by
a firm on the Malabar Coast; and we
may now add that the climate of French
Guinea, where these plantain meal
experiments were carried out, is not
unlike that prevailing in Malabar, As
in Malabar the year in Lower and
Middle Guinea is divided into two well-
defined seasons—six months of rain
and six months of dry weather. The
rain commences in the middle of May
and end in November. During the rainy
period the drying of the fruit is
restricted by atmospheric humidity, and
it is here that the artificial dryers we
have referred to come into use. The
average annual rainfall is abont 100
inches.—Indian Trade Journal.
PLANTAIN MEAL.
Some interesting experiments have
recently been conducted in FKrench
Guinea in the manufacture of plantain
meal of which profitable notice might
be taken in this country. It has been

found that the most cheap and efficient
plan, in tropical countries at any rate,
is simply to peel the plantains or bananas
and dry them in the sun, the meal thus
obtained being of excellent commercial
quality. It has been found, further,
that a hundred kilos (a kilo equals 2,204,
lb.) cf bananas in bunches as_ plucked
ought to yield 65 kilos of peeled bananas,
and that these 65 kilos should give
about 19°5 kilos of plantain meal. The
yield of plantain flour, under ordinary
conditions, is thus roughly about 20
per cent. which agrees with the estimate
arrived at recently by Mr. Hooper, of
the Indian Museum, that the average
weight of fruit required to producea
hundredweight of flour is five hundred-
weights. The manufacture of plantain
meal has recently been taken in hand
on the Malabar Coast, the climate of
which closely resembies that of French
Guinea, where the experiments referred
to were carried out. The most interest-
ing feature of the experiments, therefore,
for indian manufacturers is that in
connection with the artificial dryers,
which it is essential to use in the rainy
season. Those cost only from Rs. 300
to Rs. 750, and illustrations of them are
to be seen at the office of the Indian
Trade Journal.—indian Agriculturist,

THE CULTIVATION OF
GROUND-NUTS.
Grounpb-Nuts AS A DRy LAND CROP.
The spread of ground-nut cultivation
has been steadily advancing during the
last two years in all parts of the
Presidency. In many districts this is
quite a new crop, but it has been found
so profitable, that, wherever it has been
tried, and the local conditions have been
found suitable, its cultivation has
rapidly extended, Asconstant enquiries
are being received asking for informa-
tion regarding the cultivation of ground-
nuts, the following general instructions
have been written :—
2. Climate and Rainfall.—The ‘‘Mauri-
tius” variety of ground-nuts, which is
the one now cultivated, takes from 5 to
6 months to come to maturity. During
the first two or three months of the
crop’s growth, very little moisture is
required; the plant can withstand con-
siderable QGrought until it starts to
flower and forms its nuts. Therefore
sowing should be so arranged that the
crop will receive the benefit of good
rains during the last two to three
months of its growth. Some districts
get light rains during the south-west
monsoon, but expect their season rain
[JANUARY, 1909.
in October-December during the north-
east monsoon. Here sowing should be
done in the end of July or beginning of
August. In other districts showers are
experienced in April and May, while the
season's rain occurs with the south-
west monsoon from June to September.
Here sowing should be done as soon as a
sowing rain falls in Aprilor May. Itis
evident, therefore, that the farmer must
decide for himself whether the rainfall
is suitable, and, if so, what is the best
time for sowing.
3. Soil.—Ground-nuts should not be
grown on a heavy stiff soil for two
reasons. Firstly, though the plants
appear to be growing well, the yield of
nuts is small. Secondly, the difficulty
and cost of harvesting the erop is too
great to render the crop as profitable as
other crops, which can be grown on
such land. Sandy or loamy soils are
perhaps best suited to this crop, and it
is essential that the land should be well
drained as the ground-nut does not like
a soil where water can stand. In fact,
when quite young, evena very heavy
rainfall will often injure the crop and
check its growth.
4, Preparatory Cultivation.—It is
most essential that the land should be
properly cleaned and treed from weeds
before this crop is planted; because,
during the last two months of the cron’s
growth it is impossible to doany weed-
ing, and this, being the time when the
season’s rain falls, is naturally also the
time when weeds get ahold on to the
land and thereby diminish the yield.
Korai and Hariali are probably the two
weeds which most affect the yield of
the crop, and every effort should be
made to destroy these by cultivation,
when the land is fallow, %.e., during the
dry season. If theland is clean, probably
three ploughings and cross-ploughings
will suffice.
rad
5. Manuring.—This should be done
before the last ploughing and : cross-
ploughing. If cattle manure or village
sweepings are used, this should be
spread evenly on the field, and not left
in heaps to dry up with the sun. All
large lumps of manure should be broken
up so as to distribute the manure as
evenly as possible, and as soon as itis
properly spread, it should be ploughed
in. It will always pay the cultivator to
mauure his land for this crop. Cattle
manure. village sweepings and ashes are
always of value and can be applied at
the rate of 15-20 cart-loads per acre.
6. Seed.—_When purchasing _ seed,
always buy the nutsin theshell, Ground-
nuts for seed should always be saved
from the previous season’s crop. The
JANUARY, 1909.]
nuts should be shelled by hand, and
only good, sound, well-filled kernels
should be used for sowing, All mouldy
kernels should be rejected.
7. Sowing asa Pure Crop.—The usual
method of sowing consists of dropping
the seed inthe plovgh furrow behind
each plough. This is not only very
wasteful of seed, but the plants are much
too close together to develop properly,
and it is impossible to do any after-
cultivation except with the hand hoe,
which is always expensive, while if
exceptionally heavy rains are experienc-
ed. the crop is often liable to become
waterlogged. A better method of sowing
is to drop the seed at intervals of 6-9
inches according to the quality of the
soil in every third plough furrow. In
this way, only 10-12 Madras measures of
kernels instead of 383 Madras measures
are required to sow anacre, Hach plant
has ample room to develop, and if care
is taken to continue the furrows up to
the edge of the field, after-cultivation
ean for the first three months be done
with the bullock-hoe or Danthelu. The
inter-cultivation slightly raises the land
along the rows into the wide low ridges,
and this, besides keeping the soil mellow,
considerably improves the drainage.
8. Sowing as a Mixed Crop.—As
ground-nutstakefivemonths togrow, itis
the practice in the South Arcot District
to take a catch crop of some cereal, such
as cumbu or cholam, off the land at the
same time, | For this purpose a3-4 month
variety of such is usually chosen, so that
the cereal crop can be reaped while the
ground-nuts. which are dribbled in, after
the cereal has sufficiently grown to shade
the ground are still small. The method
usually adopted is to sow the cereal
broadeast, covering the seed with a light
plough, after which the ground is levell-
ed and the seed-bed is made firm by
dragging a harrow made of thorn
branches across the ploughing; when
the cereal crop is6 inches or so high,
opportunity is taken after a rain to weed,
hoe and thin the crop. A second hoeing
and even sometimes athird is given if
rain occurs and cakes the _ surface.
When the cereal is about to flower, the
seed of the ground-nut is dibbled in by
hand at intervals of about 9 inches
apart. This careful method of cultiva-
tion greatly benefits the cereal crop, and
prepares the land for the subsequent
crop of ground-nuts. Tenaior Ragi is
often grown asa cereal on land com-
manded by a well, instead of the
ordinary dryland cholam or cumbu.
9. Inthe case of Ragi, the crop is trans-
planted after the land has been laid out
into square beds and irrigated, aud the
93 Edible Products.
ground-nut is dibbled in later as des-
cribed above at intervals of about 6
inches. The Tenai is sown broadcast as
in the case of cumbu and cholam, and
after sowing, the land is laid out in beds
for irrigation, if thisis found to be neces-
sary. As the straw of this crop is
brittle, and as it matures early, the
ground-nut is naturally sown after the
Tenai has been harvested either by
hand or behind the plough.
10. If ground-nut is to be grownin a
district where the drill and the other
implements for cultivation are used, the
same system of taking a catch crop
cereal could be adopted. The cereal
could be sown in 18 inch drills and the
ground hoed between the rows with the
Danthelu or bullock hoe. At the right
time the ground-nut could be dropped
behind the plough in a furrow made
midway between two rows of the cereal.
After the cereal is reaped, inter-cultiva-
tion can still be continued between the
rowsof ground-nut. This method of
cultivating a cereal ground-nut crop has
been tried with success at the Palur
Agricultural Station.
11. After-cultivation.—The usual
method of cultivation is to loosen the
soil between the plants with the hand
hoe. This means that coolie labour
must always be available, or that the
crop must suffer from want of cultiva-
tion. Thescarcity of labour is one of
the serious drawbacks to the present
system of cultivating ground-nuts, and
will always be so, especially in dry red
soil tracts which cannot support a large
population. Hence the .aethod of sow-
ing the crop in rows and doing the inter-
cultivation with the bullock hoe is
strongly urged. Frequent hoeings,
whether by hand or by the bullock hoe,
are often necessary. No definite number
of times for doing this can be given, as
so much depends on the season, but it is
safe to say that for the first three
months hoeing should always be done as
soon as the land is dry ‘enough after a
good rain. This helps to keep the
moisture in the ground, it enables the
forming nuts to penetrate into the soil
and it keeps down weeds.
12. Harvesting.—The crop should be
ready to harvest at the end of five
months. The exact time must, however,
be learnt by the cultivator himself.
When the stalks to the underground
pods have dried and the skin on the
kernels has turned pink, the crop can be
considered ready for lifting, but there
will always be a few pods near the ends
of the branches which are still quite
young, when the bulk of the crop is ripe.
The method of harvesting also varies
Edible Products.
with the local conditions of soil and cli-
mate. Onvery loosesandy soil it will be
found that by loosening the soil under
each plant practically all the nuts will
remain adhering to the branches from
which they cau be picked, Often in
South Arcot, on such light soil a mam-
mootie is attached to a draught pole
and worked like a plough through the
crop to loosen the soil at a depth of
about four inches. If the crop has
become too ripe, or if the soil has baked
hard, many of the nuts will be left in
the soil; in this case it would be better
to remove all the tops first, pick any
nuts which adhere to them, then loosen
the soil with a mammotie to a depth of
4 inches, and have the crop collected
by women, who carefully go through
all the soil and pick out the nuts.
When the nuts have all been collected
they should be thoroughly dvied before
storing, by spreading out in the sun.
In the evening they are heaped up and
covered with straw, and again spread
out the following morning. This con-
Pee until the ground-nuts are quite
ry.
18. VYield.—This naturally varies with
the treatment. With good cultivation,
sufficient manuring anda normal season,
a vain-fed crop can be expected to pro-
duce a crop of 700-1,200 Madras mea-
sures. Many people who try this crop
are at first encouraged by the large
yields obtained from poor soil without
any manure being applied, and are
afterwards disappointed when the
same treatment in the following season
does not produce such heavy yields.
As previously mentioned, it will always
pay the farmer to manure his land for
this crop.
14. The Disposal of the Crop.—The
ground-nuts themselves, as arule. find
a ready sale, though sometimes in a
new district, where the cropis unknown,
there is difficulty. In such cases, the
ground-nut oil is usually saleable, and
the kernels can be crushed as any other
oil seed in the ordinary country oil-mill.
One hundred pounds of ground-nut
kernels will produce from 36-40 pounds
of oil. The cake which is obtained can
be used either as cattle food, or it can
be applied directly asa manure. In the
South Arcot district many of the culti-
vators apply ground-nut cake at the
rate of one candy per acre to the wet
lands for paddy, so that their village
manure will be available for the culti-
vation of the ground-nut crop; Experi-
ments have been started at the Palur
Agricultural Station to find out whether
ground-nut cake will not be equally pro-
fitable, when applied as manure to the
ground-nut crop. Ground-nut straw,
[JANUARY, 1909.
when dried, makes excellent fodder for
cattle, and should be mixed with the
straw of cereals for feeding. ;
IRRIGATED GROUND-NUTs.
15. Ground-nut, as a dry irrigated
crop, is now. extensively grown in the
South Arcot District duving the hot
weather months, and the rapid exten-
sion of this cultivation shows how pro-
fitable it must be from a monetary
point of view. There seems to be no
reason why this method of cultivation
should not be extended to other dis-
tricts, where the soil and water-supply
are suitable even if the ground-nut, as
a rain-fed crop, cannot be grown.
_ 16. Thesystem of cultivation of the
irrigated ground-nut crop in South
Arcot is merely an adaptation of that
adopted for the rain-fed crop, and as
the expected yield ‘is greater the land
is more heavily manured. The crop is
usually grown mixed with ragi, the
land being laid out into small square
beds after sowing ragi broadcast, and
the ground-nut dibbled in afterwards
as described above. Occasionally, if the
land cannot be prepared at the right
season, ragi seedlings are raised in a
nursery and afterwards transplanted.
Sometimes the ground-nut is grown as
a pure crop, the seed being dibbled in
6-9 inches apart in the dry beds before
irrigation, and watered immediately
after the sowing is completed. Too
close sowing is the principal objection
to this method. The cultivator still con-
tinues to plant the ‘‘Mauritius” nut at
the same distance that formerly he
planted the ‘‘country” ground-nuts,
and seems not to have realised that,
whereas the “country” ground-nut
formed-its pods near the crown of the
plant, and could therefore stand to
some extent this close planting, the
‘“*Mauritius” variety forms its nuts all
along the main branches. Thus by plant-
ing closely the Mauritius nut with its
flat spreading habit soon covers the
ground and the branches are thus forced
to grow up into the air. With this
close planting, proper weeding and hoe-
ing soon become impossible, besides
having all to be done by hand. In
consequence, the soil becomes hard and
caked, while weeds which have only
been checked while the crop is young
soon spring up when weeding has to ©
stop. This close planting also means
a great waste of water. The whole
surface of the ground has to be flooded,
and unless the land is hoed by hand
(an operation which is both expensive,
if done thoroughly, and often requires
more labour than is available), the water
soon evaporates from the surface of
the ground, thereby entailing much
more frequent waterings.
JANUARY, 1909.)
17. Cultivation and Sowing.—The
method of cultivation adopted on the
Palur Agricultural Station is still under
trial, but there is every reason to believe
that equally good, if not better, crops
can be obtained at great saving of seed,
water, irrigation, and hand cultivation.
As recommended in the case of the rain-
fed ground-nut crop, the seed is sown
in every third plough furrow, the kernels
being dropped at intervals of 6-9 inches
in the furrow. Before sowing, the land
is irrigated, and as soon as it is dry
enough the surface is levelled with a
harrow. The moisture in the soil is
sufficient to germinate the seed, and
when the crop is once up the rows
can plainly be seen.
18. After Cultivation and Irrigation.
—Furrows for irrigation are opened with
the country plough between the ground-
nut rows, and water is allowed to run
down these and thus irrigate the crop
without flooding the whole surface of
the land. Occasionally, if the land is
not level, subsidiary channels have to
be made across the rows from which
the crop can be irrigated in each
direction along the furrows. After each
irrigation, as soon as the soil in the
furrows is dry enough, the surface soil
in the furrow is worked with a bullock
hoe. This prevents the rapid evapor-
ation of water from the surface, The
next irrigation is not given until it is
seen that the crop actually requires it,
In this way for the first two-three
months, irrigation should not be neces-
sary more often than once a fortnight,
and often the intervals between irriga-
tions are considerably greater. The
time between the irrigations must, how-
ever, be left moro or less to the discretion
of the cultivator, as this depends toa
great extent on the texture of the soil.
As long as the plants look vigorous
and healthy in the early morning before
the sun is hot, irrigation is unnecessary.
Whenthecrop nearly covers the ground,
it is not possible to continue working
between the rows with the bullock hoe,
and the furrows must then be left open
after the last irrigation, sothat watering
can be continued without disturbing
the crop. During the last two months
it will be found that more frequent
irrigations are necessary. The plants
are now forming their nuts and require
a greater quantity of water. At the
end of five months from the time of
sowing it will be found that the majority
of the nuts are fully formed, Irriga-
tion must then cease in order to ripen
off the crop, The harvesting is similar
to that described above for the dry crop,
except that the land must once more
be irrigated to lossen the soil sufficiently

gated crop will vary from _ 1,000-2,000

culture, Madras, 1908.
TAMARIND CULTURE.
From time immemorial the tamarind
ranks among the useful trees of India.
There is scarcely any family of trees
that are more generally useful in tro-
pical climates than the tamarind tribe.
The Arabs first learnt its essential
properties from the Hindus, and thence
it gradually made its way into Europe.
It was at one time known as the Indian
date among the ancient Arabs and the
Persians. In EKurspe it became known
as Tamarindus Indicus. It grows every-
where in India with a little care. In
preparing plantations the rainy season
is the best one. The seeds should be
strewn on damp soil, and after a lapse of
two or three years the tree grows big
enough. In the forests and hilly regions
these trees abound in great many num-
bers. The tree grows big within a few
years and lives for a considerable length
of time. The height of it varies from 75
to 80 feet. The outspreading branches
of these give a beautiful aspect. The
circumference of the trunk is 24
feet. The trees flower in the spring and
fruits ripen in winter. From five to six
maunds of fruits can be gathered from
a full-grown tree. The tamarind fruits
are used in preparing condiments and
are exported in large quantities to
foreign countries. The tamarind is the
bare necessity of life with every Indian
villager. He may live without mangoes
or jack fruits, but this he cannot dis-
pense with. From the green leaves to
the outer husks are used as eatables by
the Indian villager. There is a story
current in Bengal about the usefulness
of the tamarind. There lived at one
time a logician in Nadia. He had one
day no other articles of food except
some rice in his house. When inter-
rogated by his wife as to what she
should prepare for curry, the logician
got up in haste and directed his eyes
towards the tamarind tree. His wife
took itin her head and forthwith came
out of the house to pluck some tamarind
leaves wherewith to prepare a nice
curry, When the logician returned
home and sat down to dinner, her lov-
ing consort got a dish of tamarind curry
which he partook of with great relish.
The logician, after eating to his heart’s
content, remarked: ‘Ours shall be no
want so long as this nectar-giving
Edible Products. 26
tamarind tree is in our house.” Though
this ig current as astory in Bengal, to
bring home to the mind of our men the
usefulness of the tamarind, yet we can,
by no means, overlook the importance
underlying the properties of this tree.
It has a good deal of medicinal
properties conducive to human health.
The green tamarind when eaten aids in
the secretion of bile and is an antidote
to rheumatism. The viscid substance
of the ripe tamarind: when pasted over
a boil helps to bring it to head soon.
If applied at the top of a betel rind
and placed a suppositoria on the anus of
a child it will have the effect of loosen-
ing its bowels.. The tamarind is required
for preparing confectionaries and tartaric
acid. A kind of medicated salt is pre-
pared out of its husks burnt into ashes.
The leaves, when applied, after it has
been pestled over some parts of the
body afflicted with pain, produce a kind
of soothing sensation ; the salt prepared
out of its ashes is a good medicine for
dyspepsia.
Place some leaves in hot water, and
when they are well boiled put them
on a cloth coloured in blue, and it will
give a crimson hue. The silversmiths
in the Deccan use a kind of acid pre-
pared from the tamarind to brighten
the gloss of silver.
The stone of the fruit is generally
thrown away as useless things by our
men. Our countrymen do not know
its proper use, Mr. David Hooper writes
in the Agricultural Ledger, 1907, about
the use of its stone. He says: ‘“ During
the time of famine the poor people
eat the tamarind stones.” The tamarind
trees are mostly to be seen in Madras
and Central India.
The stones of the tamarind are first
soaked in water for about half an bour
and then boiled for eating. Some fry
them first and then boil. When they
are well boiled, take off the outer
covering and the kernel will give a
good relish when eaten. The kernel is
sometimes dried in the sun_ or fried
and then pulverised into fine flour.
Cakes or bread can be prepared from
this flour.

science, these stones when pulverised
are used in cases of rheumatism. Accord-
ing to the Unani system of science,
the pulverised powder is used in cases
of ringworm. Dr. White says: “The
powder can be used asa poultice over
the boil.”
From the pestled stones, when boiled, a
sort of gruel is obtained, and this is much
used in weaving silk cloth. It is also
used for binding books and for making
leather harness. Its sticky substance
is again used for joining broken wooden
bars, ete. {[t has become known from
an account writtensome fifty years ago
in an Agri-Horticultural Journal that a
kind of oil was obtained from the stones
of the tamarind. The quantity of oil
obtained from the stones was small
compared with the labour required to
undergo for producing it, besides no
standing business has ever been heard
to have been lucrative from the sale of
this oil.
We, however, think that an industry
can be easily got up in the market from
the stones of the tamarind; in our
ignorance we throw away much of the
wealth lying at our door. The stones
can be easily brought from the villages,
and with the aid of an electric flour
machine these can be pulverised into
flour. A small capital is required to
start a business. We hope some of our
readers will make an experiment in this
line of business.—Indian Heonomist.
COCONUTS IN THE DRY ZONE
OF CEYLON.
By J. C. WILLIS.
(Illustrated.)
There appears to be an_ impression
abrcad that the coconut will not grow
in the dry country of northern Ceylon.
That this is untrue may be seen bya
visit to any village there, where the
tree may be seen Aourishing in the
neighbourhood of the tank, in which
place it gets acertain amount of seepage.
A little water, but only a little, is
required for the successful cultivation
of this tree. The photographs reproduc-
ed with this article show the early
stages of cultivation on the irrigable
land at Maha-iluppalama Experiment
Station, 11 miles from Kekirawa (north
of Dambulla on the great North Road).
The younger trees occupy 27 acres on
irrigable land, about half a mile from
the tank. The seed nuts were put into
the nursery in August, 1907, and in April,
1908, they were planted out in holes of —
3 feet cube, partly filled with soil.

Drains were then cut, and they were
watered from the tank ela, once a month
for one day, until September, since when
they have not been watered, and
probably will not want any more.
The older trees were planted out on
six acres of unirrigable landin May, 1907,
but about 200-500 yards from the tank,
where there must probably be some
seepage. They were watered at inter-
vals of 14 days till the N. E. monsoon.
In places they were watered twice in
June and July, 1908, and have had no
other water. The ground could not be
cultivated till after the photograph was
taken, but a space was kept weeded
round each tree.
The irrigable land is in a fine state of
tilth, it will be noticed, the tracks of the
teeth of the Plant Cultivator showing
clearly. The unirrigable land has been
tilled since the rains, but at the time of
these photographs (Aug. 24, 1908) had not
been tilled.
These photographs show the possibility
of cultivating coconuts successfully on
the tank lands, with the use of the very
smallest amount of water. The growth
of trees at Peradeniya, from seeds from
the same tree, and of the same age, is by
no means so good.
There can be no doubt that the irri-
gable land of the dry zone is the “ best
unrealised asset ” the island has, and we
hope to see it the seat of a large agri-
cultural enterprise.
THE COCONUT PALM: ITS RELA-
TION OF WEATHER TO CROPS.
The following paper was. read by
Mr. J. D. Vanderstraaten, at the meeting
of the Board ot Agriculture on 3rd
December, 1908 :—
The want of literature ox the coconut
palm has been often noticed, and is re-
markable considering the great value of
the palm to this Island. It not only
contributes largely to the good of the
people, and is directly or indirectly their
chief cource of income, but it furnishes
the Government with 12 per cent. of its
Revenue through arrack rents, and
supplies the magnificent Harbour of
Colombo with more than half of its ex-
port shipping tonnage, and may well, if
the cultivation of the palm be encouraged
and stimulated, supply quite two-third
to three of the tonnage. The American
Government, shortly after the acquisition
of the Philippine Islands, began the
scientific study of the coconut palm,
which previously had not been, I believe,
Edible Products,
the subject of scientific investigation ;
and itis very desirable that the Ceylon
Government should, if it has not begun
already, undertake researches into the
life history and cultivation of the coconut
palm on almost the same lines as the
valuable researches concerning Para and
other rubber-yielding trees. For, al-
though the coconut palm is such a
familiar tree to us all, as usual with all
things with which we are familiar,
accurate knowledge is wanting and much
error prevails, some of aserious economic
nature, é.g., it is generally believed by
the larger proportion of coconut garden
owners (am I overstating it when I put
it quite as high as 90 per cent?) that
manuring is ultimately and soon hurtful
to the tree, even fatally so, though at
first attended with some increase of crop ;
this I say is a serious economic error, for
the produce of the coconut plantations
in the Island may easily be at least
doubled by manuring the gardens. The
experience of those who have cultivated
and manured gardens previously innocent
of either tillage or added fertilizers, has
been that a three or even fourfold in-
crease may be obtained and permanently
maintained, without any shortening of
the life of the trees. But, to convince
the people of this and of it being quite
within their means to properly cultivate
their lands, it would seem necessary that
a Government scientific department
shouldcarry out experimextal cultivation
and issue manuals in the vernacular,
giving the results and all required
directions. The advantages that would
result to the country, to the Government
and to the people within less than a
decade, would be incalculable.
Amongst other misconceptions about
the coconut tree may be mentioned the
general belief that each tree bears twelve
bunches of fruit a year ; that heavy rain
is beneficial, and the heavier the more
beneficial; that, on the other hand,
drought is hurtful, even drought of the
kind that ordinarily prevails during the
early months of the year. In this paper
I propose to consider the relation between
the weather and crops, and it is not
inopportune, seeing that the rainfall this
year has been throughout the Island
much below the average, and in some
districts the drought has been unpre-
cedentedly severe, as in the Puttalm
district.
At the outset I must disclaim having
definitely succeeded in tracing the exact
time relative between the weather and
crops. I. have formed a theory out of
some data where many nezessary data
are required for accurate conclusions.
It is with a view to elicit discussion and
Hdible Products.
to have my theory confirmed by others,
or satisfactorily controverted, that I
venture to submit this paper.
That there must be a relation between
the weather und coconut cropsisa simple
truism, but can we reduce it to rules for
our guidance in estimating future crops
or in devising measures to counteract the
effects of unfavourable weather? The
‘question is not one merely of the amount
of rainfall in a single year (the tree is one
that is blossoming and bearing fruit all
through the year), but of the intensity
of the rainfall at various times, of its
distribution, of the degree of saturation
of the soil, the variation in the saturation
from thorough as in the early weeks of
the monsoons to greater or less dryage
during drought, of the variation in the
temperature and moisture of the air, the
degree of sunshine and light as affecting
transpiration and the formation of
chlorsphyl, and also the eletrical condi-
tion of the atmosphere,
We all know roughly that extreme and
prolonged saturation of the soil, as also
extreme and prolonged dryage, are
equally unfavourable. We know that
extreme heat and extreme cold, that a
prolonged period of dark cloudy days
are all unfavourable to the production
of blcssom, while it has been generally
noticed that a highly electric condition
of the atmosphere is extremely favour-
able, but here our knowledge ends.
When we enter into details our opinions
differ greatly. We have not before us
allthe data for definitely framing our
opinions, and it is extremely desirable
that full observations should be carefully
recorded of the various tactors that
affect coconut crops.
The experience of practical planters of
the results of manuring and recorded
observations of rainfall and crops should
goa long way towards establishing a
fairly workable theory on this subject.
In manuring, especially in manuring a
previously uncultivated garden, we find
no increase in the crops during the first
year, simply because the blossoms for
the first year’s crops were all out and set,
and in various stages of development
already when manuring took place—
perhaps after afew months we find less
of the tender young coconut (kurum-
bettis) falling, owing to the increased
nourishment afforded by the manure, so
also we notice a slight improvement
in the kernel from the same cause.
During the second and third years there
is a marked and gradual increase of
crop still due to the improved vigour of
the trees and the consequent fertilizing
properties of the pollen which otherwise
would have been largely infertile. The
increase of crop during the third year
28
may be quite double the previous yield
or even more, but it is after the third
year that the full effects of manuring are
felt by the trees, the increase in nuts of
previously unmanured gardens being
quite four to fivefold. I was much struck
with this fact when I first began coconut
cultivation and unable to account for the
long interval required for manuring to
tell in the case of coconuts, till curiosity
led me to dissect the heart or cabbage,
the pol-bada, of a healthy tree which
was blown down by high wind. Count-
ing all the flowers from the one just
opened to the smallest spathe in the
heart or cabbage that could be examined.
with a magnifying glass, I found
there were thirty-four flower spathes in
this tree, and the smallest spathe in
the heart of the cabbage had clearly
distinguishable miniature kurumbettis
or female flowers. Now, taking sixteen
as the average number of fresh branches
(and each branch carries a flower spathe)
put forth yearly by a healthy tree, we
get two years and say twoor three
months for the last distinguishable
spathe to arrive at the crown of
the tree and burst into blossom—to this
must be added another ten to twelve
months before we can gather the fully
matured nuts from that branch. This
gives us the period of three years at
least, and I suppose a few months must
be allowed from the beginning of the
manuring period for the initial forma-
tion of the flower spathe in embryo. IJ
regret being unable to express myself
in scientific terms. Scientists whom I
have consulted tell me the flower spathe
once formed inembryo, nothing can in-
crease or diminish the number of female
flowers it contains. May we not well
conclude that rain or drought, too, in-
creasing or retarding the flow of fluid
(sap) in the trunk of the tree and
otherwise affecting it, cannot increase
or diminish the embryo female flowers
already formed, and must therefore
take the same timefor its operation as
manuring.
The records of crop and rainfall kept
by some estates bearjout also, I think, the
theory | have advanced. These records
also [I think establish the fact that
heavy and long continued_ rainfall, lead-
ing to prolonged and undue saturation
of the soil, prejudicially affect the for-
mation of fruit blossoms; but when a
period of dry, sunshiny weather, almost
amounting to drought (as in the early
months of the year), follows on such
heavy rainfalls, the conditions are ex-
tremely favourable.
The coconut tree thrives best with its
crown exposed to the sun and wind

quence through the circulation of the
sap the absorption of moisture from the
ground. The rootof the tree should be
in favourable soil with easy access to
running water.
We find the coconut tree flourishes
into an average rainfall of 80 inches as
in the Negombo district, and of about
50 inches as in the Puttalam district, but
if the occasional torrential downpours
which go tomake up the total of 80
inches in the Negombo district are
allowed for, the average would be about
50 inches—even 40 inches are not too low.
It is necessary to avoid the extreme and
prolonged saturation of the soil by
drainage, when necessary, and the ex-
treme dryage of the soil by tillage and
mulching and also to increase the vigour
of the trees by fertilizers to enable the
roots to penetrate down in search of
moisture when the surface supply is
scanty in times of extreme drought.
The drought this year has been excep-
tionally severe. but when the land has
been well tilled and mulchedI do not
think any serious harm has been done.
In the Negombo district I can only trace
the present effect of the drought in the
thinness of the kernel we have been
desiccating lately. Where the coconut
roots have had access to water I do not
anticipate any shortage of crop three
years hence, but quite the contrary.
If owners of coconut gardens would
even till their lands well (by ploughing
or turning on the soil toa depth of 5 or 6
inches) and spread coconut fibre refuse—
a cheap and satisfactory mulch to be
had for the cost of transport—or use
some other mulchy substitute, they will
not even suffer the loss of tender nuts
dropping in consequence of any drought
that may prevail. Mulching has this to
recommend it, that it not only prevents
rapid loss of the moisture in the soil by
capillary attraction, and so conserving
it for the use of the tree, but by obstruct-
ing evaporation prevents the cooling
down of the soil, which always requires
to be warm for production of fruit
blossoms.
THE INDIAN TEA TRADE IN 1907-08.
A PROSPEROUS YEAR.
The following particulars are extracted
from the *‘‘ Review of the Trade of India”
in 1907-08 :—
The Indian tea trade has enjoyed
another prosperous year. The World's
consumption has apparently caught up
supply, and everything points to its
increasing in the futurejat a correspond-
ing ratio. The only ms

DISQUIETING FEATURES
of the year’s trading were the temporary
inflation of values for lower grades of
leaf, which have appreciated by 70 per
cent. since 1906, at the expense of the
better teas, and complaints of a general
decline in quality; but the principal
excuse for coarse plucking has been re-
moved, now that tine market seems to
have recovered its sense of proportion.
In any event India could not hope to
have benefited long by the extravagant
rates for her poorer stuff, for they would
have provoked the competition of the
cheaper China tea and encouraged in-
creased cultivation in Java.
THE ADVANCE IN CONSUMPTION,
which followed the reduction of the
import duty in the United Kingdom to
5d. per lb., has been maintained. In-
ternal absorption is increasing and tea
shops are now a common feature of many
bazaars, particularly in Southern India;
but it is in the expansion of the Con-
tinental markets that the prospects of
the Indian industry centre, and of these
the Russian market in particular is
showing remarkable development. The
following table illustrates in the last
three calendar years, compared with the
year 1890, the astonishing growth in
absorption of teas from India and Ceylon
on the Continent :—
1890 14,001,824 lbs.
1905 129,881,250 ,,
1906 oe ae 162,461,824 ,,
1907 (estimated) ... 171,500,000 .,
THE RUSSIAN MARKET
is of particular interest and importance.
Its development dates from the discovery
that Indian dust gives a greater strength
to ‘‘tablet” tea than Chinese. Indian
tea reaches Russia not only by direct
shipment, but also across the land
frontier of India and by re-export from
the United Kingdom, Germany and China.
It has been estimated that Russia in the
nine months ending September 30th, 1907,
absorbed 30,542,081 lbs. of Indian and
Ceylon teas as compared with 24,566,329
lbs. for the same nine months of the
previous year. These figures exclude
imports of brick tea from China, in which
Indian dust has been blended, estimated
at 8,000,000, lbs. in 1907 or proportionately
6,000,000 lbs. for the period January-
September. Indiais encouraged to direct
importaion into Russia by the pre-
ferential duty on her tea and that of
Ceylon carried by the Trans-Siberian
Railway, and it is announced in this
connection that a double service of
steamers will be established next season.

The duty on tea in Germany was reduced
in 1906 to 14d. per lb., and this, aided by
a vigorous medical campaign against
beer and coffee, is likely to encourage
imports. Holland and Belgium are two
other promising markets. As regards the
COMPETITION WITH CEYLON,
it remains to be seen how far the intro-
ducticn of rubber there will ultimately
affect production, for the cultivation

RESULTS OF IMPROVED PROSPECTS
in the tea trade are illustrated by the
appreciation of shares in the market.
Mr. George Seton has calculated that the
shares of 170 Tea Companies registered
in London have enhanced in value from
£14,400,000 to £21,600,000, or by no less
than 50 per cent. between January, 1905,
and November, 1907. China supplied half
the requirements of the United Kingdom
twenty years ago ; in 1907, the proportion
had been reduced to six per cent. and is
only sustained at that level by the com-
petitive price for lower grades of Indian
and Ceylon teas. Theimports of tea into
the United Kingdom in 1907 were as
higher altitudes. The follows :—

Kingdom tend proportionately to re-
duce. as direct shipments take the
place of consignments to London on
optional bills of lading, her share of the
total exports stands at 746 per cent.
The expansion in the Ceylon. and China
figures is due to Russian requirements,
and the heavy decline in direct ship-
ments to Canada should not be regarded
as an index ofa contracting market.

advances, ‘Lhe figures to Australia were

eontinue under suspicion of great inaccuracy, and for this the planters must be

It will be interesting to tea planters
to note some figures on tea drinking in
Burma given in the seventh triennial
report just issued on Burma’s trans-
frontier trade. Taking the population
of the province as at the last census,
the quantity of tea consumed annually
is about two pounds per head of popula-
tion. The advance in the consumption
of wet or pickled tea was 398,000 pounds.
During the financial .year 1907-08 the
quantity of pickled tea imported from
the Northern Shan States was 16,359,878
pounds, and dry tea 2,477,952 pounds,
besides 1,389,000 pounds imported by sea.
The wet or pickled tea is considered a
luxury by the Burmans. The trade of
the province is altogether in a very
healthy condition. The total value of
the inland foreign trade shows an in-
crease of 376 lakhs, or 34°76 per cent, over
the figures of the previous triennium.

MANIOC OR CASSAVA.
By EDWIN B, CoPELAND.
(Continued from p. 529.)
CLIMATE AND SOIL.
Manioc is essentially a tropical crop.
Even the hardiest varieties are killed by
any frost that kills tomatoes. As a
result, growers in the United States
must use the earliest varieties and
harvest their crops in from seven to nine
months after planting. The average
yields with decent cultivation are not
over five tons of roots per acre. This is
as high a yield as c ould be counted on in
the Philippines in the same time; in the
variety thatis raised here, it is after
this age is passed that the most rapid
growth occurs. As the plant is repro-
duced by stem cuttings, it is necessary
ina country subject to frosts to bury
the stems during the winter. This
makes seed material somewhat expen-
sive and of low vitality, so thata con-
siderable percentage of the cuttings set
out are likely not to live, and this in
turn leaves vacant spots in the field and
cuts down the yield. Itis only in lands
nearer the equator, where the temper-
ature is comparatively uniform and
moderately high, that manioc can
develop with its characteristic luxu-
riance. An altitude of 3,000 feet is the
upward limit of the common occurrence
of manioc in Hawaii;inthe Philippines
its culture for food can well be carried
higher.
Aside from the fact thatit must be
warm, manioc is very modest in its
demands upon the climate. To drought,
the arch enemy of most cultivated
plants, it is fairly immune. For the
month or so after the cuttings are
planted, they need as much rain as do
most other plants at the same stage of
growth, After this time, a moist
temperature and occasional rain pro-
mote a most thrifty growth and _ the
succulence of the roots. Roots used for
food have a better texture in wet seasons
than in dry. Dry weather, however,
| JANUARY, 1909.
at least such dry weather as occurs in
the Philippines, never kills manioc, and
rarely, if ever, comes near stopping its
growth. The typical insular climate,
with a moderate amount of moisture in
the air at all times, is most favourable
formanioc. Never is it seriously injured
by any drought occurring in these
Islands, and it is likewise not hurt by
heavy rainfall, unless it grows in heavy
and undrained soil.
As is true of all drought-resisting
plants, manioc wants all the light it can
get, and plants at all shaded or planted
too close together must not be expected
to be very productive. The ideal soil
for manioc is rich, fairly deep, and open.
Since very rich soils are often compact
and heavy and undrained, and since its
tolerance of drought makes it thrive
better than most cultivated plants on
sandy soils, these are in many places
regarded as especially favourable to it.
The roots do not endure standing water
in the ground around them; low, heavy
soils should therefore be drained or
used for some other crop. When heavy
soil is used in Jamaica, manioc is planted
in raised ridges, and this is the general
practice in the French West Indies.
The harvesting of the roots will ob-
viously be easier and more complete in
light than in heavy soil.
As to the demands of manioc on the
food in the soil, there are two opposite
opinions, some writers claiming that it
is conspicuous among cultivated plants
for the rapidity with which it exhausts
the soil; others, that it is like other
starchy crops in taking very little from
the ground. The former view is
supported by, and is probably due to,
the fact that in the Straits Settlements,
Africa, and to a great extent inSouth
America, manioc is raised on forest
clearings, which are used a few times
and abandoned, When starch became a
staple product of the Federated Malay
States, a large amount of land was cut
over in this way and then abandoned,
with the result that the destruction
of the forest was out of proportion to
the permanent agricultural develop-
ment. The Government met this diffi.
culty by refusing to lease Jand for
manioc cultivation unless some _per-
manent crop, such as coconuts or rubber,
are planted at the same time, and this
regulation has been widely const:ued as
evidence that manioc is a robber crop.
But it is no peculiarity of manioc that
it thrives best on virgin soil. Various
Philippine crops, including upland rice,
are raised according to exactly the
same system, and one of the hardest
problems in forest regulation here has
JANUARY, 1909.]
been the constant abandonment of
plats of cultivated land and_ the making
of new “caingins” or clearings for
temporary use. Chemical analyses do
not at all support the view that manioc
isa hard crop'on the soil. . The total
ash in the roots is commonly less than
2 per cent. of the dry weight, and the
nitrogen hardly more than 0° per cent.
Manioce does use nitrogenin the forma-
tion of hydrocyanic acid, beside in the
Ways common to most plants, and
may therefore exhaust this food dispro-
portionately. This danger can be avoid-
ed by raising a leguminous crop with
the manioc or alternating withit. The
most promising leguminous crop here is
the mongo. Unless the soilis rich in
lime, the addition of this cheap food will
be good for both the mongo and manioc.
ENEMIES.
A scale in Africa causes yellow spots
on the leaves and leaf-minor lives in
them, but neither causes appreciable
damage. The same is true of insects
which occasionally gnaw them. Old
roots left in the ground in the Philip-
pines are often chambered or consumed
by insects, but young or fresh roots are
never attacked.
Leaf-spot fungi occur in the Malay
States, Africa, and, America, but no-
where do appreciable damage. The only
known serious disease of manioc is a
leaf curlin East Africa, called by the
natives ‘‘maratschi.” It is a communi-
cable disease, but no micro-organism is
known toecauseit. No variety of manioc
is free from it. A Madagascar variety
called Mpesazi, is the least generally
attacked. A sound plant of this variety
twelve months old may have 12 kilograms
of rooots, but the average yield of
thirteen plants with the leaf-curl was
only 0°41 kilogram.
No disease of manioe is known in
the Philippines. Their most dangerous
enemy here isthe hog. Wild hogs do
considerable mischief when they get
access to manioc, but they of course can
be kept out by good fencing.
CULTURE.
Knowledge of what is really best in
the culture of manioc is very limited,
the plant never having received a frac-
tion of the study which has been
bestowed on all the important crops of
temperate lands. On manioc we have
for the most part only scattered observa-
tions, and these are not always _ too
reliable. In the equatorial belt, where
manioc thrives best. the most usual
treatment of it is the most complete
neglect. The only attention it usually
receives in the Philippines is sticking

Africa, and South America it receives
no more care. The most careful study
has been given it in Florida and Jamaica ;
in the former all the conditions are very
different from those here, and in thé
latter the subject most studied has been
the selection of varieties.
Manioc is in practice always reproduc-
ed by stem cuttings. Seeds are used in
the Government work in the United
States in attempts to secure new and
-sweeter varieties, and in German Hast
Africa in attempts to secure immunity
from disease. So far as limited and
unsatisfactory experiments show, the
seedlings are likely to have sweeter
roots than their parents. However, in
Paraguay the seed of the sweet culti-
vated varieties is said to be very
unreliable and likely to produce poison-
ous roots. The stems will grow if
used as soon as cut and are presumably
most vigorous then; but they have
stood shipment from Jamaica to India,
and in Paraguay have been kept alive
through six months of hot weather,
provided the epidermis was not bruised
or broken and they were kept dry.
Only sound stems of sound plants
should be used. Cuttings 10 to 20
centimeters. long will produce thrifty
plants. Some writers advocate the use
of longer ones, and it may be that their
use where there is plenty of material for
propagation will give the plants a
stronger start. The cuttings are buried
horizontally in some places, placed erect
with the lower end in the ground in
others, and planted obliquely in still
others; they grow everywhere. The
crop will perhaps be more easily har-
vested if the cutting is not erect. If it
is erect it is advisable to plant in the
ground the original lower end, so that
the polarity of the cutting will not have
to be overcome when it begins to grow.
Statements as to the proper distance
between plants differ widely, and this
depends of course upon the soil and
climate, and upon the natural growth
of the variety planted. - On good soil a
distance of one meter in each direction
can be recommended for the Philippine
variety; this puts 10,000 plants on one
hectare of even ground. If more room
for cultivation in one direction is desired,
the same stand can be obtained by putting
the rows 125 centimeters apart and the
cuttings 80 centimeters apart in the rows.
A somewhat more ample spacing is better,
if a short-lived catch crop is interplanted,
Some writers condemn the use of any
other crops with manioc, but it seems to
me that if well chosen they have decided

advantages. Theuse of cane in this way—
as is practised, for instance, in Mauritius
and Reunion—is distinctly bad from the
standpoint of either plant, for they
compete throughout their lives and reach
their greatest development at the same
time. Maize is used on a plantation in
Basilan, and is harvested and out of the
way before the manioc needs all the
space. But if a catch crop is to be used,
there is no reason why it should not be
one which, like mongo or some other
legume, will leave the soil actually
bettered by its presence. There is at our
door a market for mongos as human food,
and there are various legumes which
produce a fodder which could be mixed
with the waste from the starch mill to
make a well-balanced fodder for beasts.
While, so far as I know, no comparative
tests have been made, there is no doubt
that thorough ploughing and harrowing
have the same general effect on manioc
that they have on other crops. In the
case of manioc, hard ground not only
prevents the proper growth and activity
of the feeding roots, as it does for other
crops as well, but it interferes directly
also with the development of the part of
the plant to be harvested. Even if the
fleshy roots became as large in hard and
uneven ground—-which they could not—
they would still be less valuable, for it is
much more difficult to clean and peel an
irregular root than a stout, symmetrical
one. Moreover, as has been seen, the
bark and cortex are strong in hydrocyanic
acid, while the starch is cunfined to the
fleshy interior; therefore a stout and
symmetrical root, having less surface in
proportion to its bulk, will contain the
least poison and the highest percentage
of starch, while an irregular root or a
very long one, such as may grow where
the ground has been cracked, will be
comparatively bitter and weak in
starch.
While ploughing is, in the abstract,
desirable, we may as well recognize
frankly that on freshly cleared tropical
land it does not pay. The laborious
removal of stumps and roots, work to
which the native labour is not used, costs
fully as. much here as in the United
States; while if fresh growth is kept
down, termites and the teeming organ-
isms of decay will destroy almost every
kind of wood completely within a year
or so. The land can be ploughed for
subsequent crops. Hand cultivation is
cheap here, and can be made to give very
good results. When manioc is planted on
» unploughed land each cutting should be
set into a spot of thoroughly worked
ground 20 centimeters deep and at least
30 centimeters in diameter. The plants
[JANUARY, 1909,
should be in rows, as regular as possible.
Because of stumps a given area will take
less plants than could be put into land
well cultivated.
If mongo is interplanted with manioc
the two should be planted at the same
time, so that the mongo may mature and
be harvested before the manioc needs its
room. It, as has already. been suggested,
the rows of manioce be 125 centimeters
apart and the cuttings 80 centimeters
apart, two rows of mongo, themselves 30
centimeters apart, can be planted between
each two rows of manioc. The two crops
will need but little more cultivation than
should be given manioe alone. Whether
or not the mongo is present, the land
should be thoroughly cultivated not more
than one month after planting, making
the ground soft and fine, and killing all
weeds—a weed is a plant of whatever
kind which grows where it is not wanted,
At this first cultivation itis advisable to
hill the manioc slightly.
Mongo needs cultivation twice within
the first two months, while manioce
might do with one, but will certainly
grow better for the greater attention.
After the mongo is removed the ground
will still want to be cleaned and worked
once. After the plants are four or four
and half months old they take care of
themselves.
The roots areready to be used for
human food at any time after they are
five or six months old. Sometimes all
the roots of a plant are taken at once,
sometimes they are dug one at a time.
In these young roots the percentage of
sugar is probably as great as it ever
becomes, but they are relatively weak
in starch, and less woody than older
ones. The roots of the Philippine varie-
ties are probably best suited for direct
use as human food when they are not
more than nine months old, although we
have seen succulent roots on plants said
to be sixteen months old, from which
other roots had been removed earlier.
In Hawaii, two year-old roots are often
hard and _ fibrous, containing little
starch, One African variety is edible
when six years old. For making meal
or manutacturing starch the reots ecan-
not profitably be gathered until they
are well beyond the best age for direct
use as human food; thus, in one African
district they are eaten fresh when about
nine months old, and not used until
twelve to fourteen months old for
making meal. In some parts of the
Philippines the roots are said to be
grated and eaten when three years or
more old.

THE FERMENTATION OF CACAO,
By Oscar Lorw, Physiologist.
(Concluded from page 534.)
Since a moderate brown colour is also
produced in white ‘‘nibs,” free of cacao
red, it follows that the brown colouration
is not due exclusively to a change of
eacao red. If the production of the
colour is due to an incomplete oxidation
ot the tannin, then there will be less
tannin found in the cured cacao than in
the fresh cacao. This agrees, indeed,
with some analytical determinations of
J. B. Harrison, published by Hart. The
fat content is assumed not to change
during the curing process, and this is in
all probability the case. The data com-
piled under this condition are as follows
for Calabacillo cacao :—

A part of the changes brought about by
curing is probably due to the action of
the living cells in the seed, before they
are killed by the rising temperature.
This would account for the decrease of
starch, glucose, and hemicellaloses, which.
may be consumed by the respiration
process, but the other changes are due to
several enzyms. A _ proteolytic enzym
brings on the decrease of protein and the
corresponding increase of amido-com-
pounds, while oxidizing enzyms, generally
liberated from the protoplasm upon
its death, cause the decrease of tannin
and cacao red and their change to other
compounds. The most conspicuous
changes are, therefore, only possible after
the death of the protoplasm which isa
desirable factor, Hence, it is a mistaken
idea of Zipperer that the changes are due
to a germination process of seeds. He has
even attributed the rise of temperature
of the fermenting pulp cacao to this
process, considering it analogous to the
behaviour of barley on the malting floor,
This error can only be explained by the
fact that he has never witnessed the
fermentations of cacao or coffee; for
germination changes are not in the least
apparent,
Edible Products.
Another result is the change of flavour.
In the fresh state the seeds have a raw
bitter, and astringent flavour, while after
fermentation and drying the bitter and
disagreeable taste has entirely disap-
peared. This change is doubtless due in
a certain measure to the decrease of
tannin ; that is, to its change by oxida-
tion to abrown substance, as inthe case
of the persimmon fruits, mentioned
above.* The flavour of the fermented
beans is still far different from that of
the prepared cacao product, which is
produced by roasting the fermenting
beans; hence a part of the taste must be
due to changes caused by the heat of the
roasting process.
The presence of oxidizing enzyms in
the seeds of cacao can be proved by the
usual reaction. Upon moistening a
freshly cut section of cacao seed with
tincture of guaiacum resin, just after
taking the seed from the ripe fruit, a
blue colour is rapidly produced, first
and most intensely in the chalaza of
the embryo and gradually spreading
over the entire seed tissue; also, the
placenta shows soon an intense blue
colour. Whena cross section through
the whole fruit is moistened with
guaiacum tincture, the chalaza of the
embryo and the interior soft stratum of
the fruit shell become rapidly and
intensely blue, then follow in order the
colouration of th2 convulsions of the
cotyledons, of the seed and the tissue of
the hard outer shell. Finally, the whole
surface of the section of the seed and
exposed tissue of the testa become blue ;
but the slime tissue or pulp around the
testa remains perfectly colourless,
presenting a most striking contrast.
If the tissue of the seed is crushed
with some water in a mortar, the filtered
liquid will show no blue colouration on
addition of guaiacum tincture and shak-
ing with air, while the unfiltered liquid
will become blue very soon. This shows
an exceptional case, namely, that the
oxidase (laccase) is present in an inso-
luble state and perhaps held in combi-
nation with an _ insoluble protein.t
Upon standing the blue colour, obtained
with the unfiltered liquid, will gradu-
ally disappear, except on the surface,
but on adding afew more drops of the
reagent and shaking, the intense blue
colour reappears. This phenomenon is
due to the presence of a reducing com-
pound in the juice.
*The opinion of Harrison mentioned above
that the decrease of the astringent taste is
dueto a hydrolysis is erroneous and would be
without analogy.
_ {This recalls the existence of a soluble and
insoluble form of catalase,
Edible Products. 86
In testing for a second oxidizing
enzym, the peroxidase, the tissue of the
seed, crushed witha little water, was
heated for five minutes to 75° C, and one
portion of this liquid was filtered, the
other not. The test with guaiacum
tincture yielded no blue reaction in
either liquid, proving that the oxidase
was killed, while on addition of a little
paroxid of hydrogen the unfiltered juice
gave an intense blue reaction and the
filtered juice showed only a trace. This
difference proves that the peroxidase,
like the oxidase, was present, but
retained as an insoluble compound—an
exceptional case.
Reactions with guaiacol were also
tried, This substance produced no
coloration when applied by itself, but
in conjunction with hydrogen peroxid a
red colour turning to brown was soon
produced in both the hard as well as
the soft layer of the fruit shell. Later,
in the testa and the; seed in general, as
well asin the slime tissue covering the
testa, only a weak, reddish coloration
was produced. This peroxidase reaction
agrees also with that just mentioned,
in so far as the slime tissue gave only an
exceptionally weak reaction compared
with all other parts of the fruit. The
slime tissue of the coffee fruit is also
poorer in oxidase and peroxidase than
the other tissues.
The further generation of the charac-
teristic aroma of cacao is of great im-
portance. Is this process due to the
action of an oxidizing enzym or to that
of a hydrolizing enzym, and does the
fermentation influence the generation
of aroma only indirectly by the develop-
ment of heat or directly by furnishing
some compound? Or, is the roasting of
the fermented cacao beans alone res-
ponsible for the aroma? The investiga-
tions thus far made do not solve this
problem satisfactorily. It may be men-
tioned, however, that Hart agrees with
Chittenden, .who declared that after a
certain stage of the fermentation ‘‘ the
cotyledons are found separated and the
vinous liquor of the pulp, which passes
through the membranous covering,
occupies this space as well as the cavities
between the convolutions. unis ee Eis
it is which hasso marked a physiological
influence and affects its flavour, the bean
being, as may be said, ‘stewed in its own
juice.’”
According to the laws of osmosis some
acetic acid aud some alcohol from the
fermenting liquor will doubtless enter
through the testa and come in contact
with the cotyledons, which thereby may
be killed, if the temperature of the
fermenting mass has not already accom-
(JANUARY, 1909,
plished this. The reaction of the cotyle-
dons after drying the fermented beans
is acid, but whether thisis wholly due
to the entering acetic acid may be doubt-
ful, since the reaction is weakly acid in
the fresh state. A stronger acid reaction
is shown by the slime tissue.
The expression ‘‘stewed in its own
juice” used by Chittenden can hardly
be admitted, since the juice of the pulp,
after being entirely decomposed by
yeast and bacteria, is certainly not the
‘‘own juice” of the cotyledons. Still,
that author attributes to it the gener-
ation of the flavour.
The opinion of J. B. Harrison that the
decrease of tannin during the fermenta-
tion process stands in relation to the
development of aromais certainly far
from the mark, as tannin cannot
produce ethereal oils by an oxidation or
fermenting process. Only colour and
taste stand in this relation to the tannin
content.
Several experiments were made by
the writer with an aqueous solution of
1to4 per cent. acetic acid containing
from 8 to 5 per cent. of alcohol in order
to imitate the composition of the
fermenting pulp juice. After twenty to
thirty hours’ digestion of pulped cacao
at 40° to 45°C. it was observed that the
pulp had died and shrunk to skinny
masses, partly separating in small
pieces, but mostly still firmly adhering
to the testa. It appears that for bring-
ing about an easy separation of the dead
pulp from the testa a bacterial enzym is
necessary, as in the case of coftee
fermentation. It was further observed
that the amount of acetic acid, which
entered by osmosis through the testa to
the coytyledons, was not sufficient ‘to
kill the oxidizing enzym, since the
freshly cut surface of these seeds rapidly
turned brown on exposure to the air.
On the other hand, it was observel that
when the freshly cut surface of the
seeds so treated was moistened with 4
per cent. acetic avid no further change
by oxidatiou took place. In this case
the oxidizing enzym was killed.
Itis stated by Hart that ‘‘ of late years
there has been a large amount of inquiry
for cacao which is but slightly fermented
or not fermented at all.” This renders
it very probable that the decomposed
juice of the slime tissue is not required
for the generation of the aroma as was
supposed. Indeed, the true aroma of
cacao is faint before roasting the fer-
mented beans. The case is, therefore,
similar to that of coffee, and is different
from that of tea. With tea the aroma
is the result of the action of ahydrolizing
enzym, yielding the volatile tea oil, as
was shown by Katayama. itt:
we
January, 1909.)
That the aroma of the cacao is chiefly
produced during the gentle roasting
process is the opinion of manufacturers
of chocolate from the fermented beans.
The fermentation seems, indeed, to have
nothing at all to do with the production
of aroma. Seeds simply dried in the
sun and then gently roasted may yield
an especially rich and aromatic chocolate,
as Safford* has also indicated. Hart
says:
No adulteration ~ * * isequal tothe
flavour of the virgin cacao, provided the
essential oil has not been destroyed dur-
ing the process of roasting, during which
process it appears to be developed.t
The question now arises, which com-
pound yields the aroma in the cautious
roasting of the fermented cacao beans ?
It is certainly not.a glucosid, for neither
the testa nor the cotyledons of the beans
develop anything like a cacao flavour
upon being boiled for some time with
dilute sulphuric acid (8 to6 per cent).
The same negative result was obtained
by boiling those materials with moder-
ately concentrated solution of caustic
potash. It seems probable that it is a
certain concomitant of the fat which
causes the production of the flavour,
after being moderately oxidized during
the drying of the beans. Only seeds
which the oxidizing enzyms have pro-
duced changes can yield the true aroma
by roasting, not the fresh beans.}
In the manufacture of the cacao
powder of commerce the fat of the
cacao is removed more or less, since a
suitable powder cannot otherwise be
obtained, but in the direct manufacture
of chocolate this removal of the cacao fat
cannct be justified. Itis claimed that
cacao fat or cacao butter is difficult
of digestion, but in reality cacao butter
is as easily digestible as cow's butter.
Besides, the removal of fat also diminishes
the aroma of the chocolate. In _ the
manufacture of chocolate in Porto Rico,
fermented cacao seeds are placed in a
small baker’s oven for about one hour,
until the testa have become very brittle

remarks to this article.

however, quoted above in regard to the in-

and can be easily removed. This roast-
ing temperature is kept considerably
lower than that required for baking
bread. The cacao butter is not removed
in Porto Rico, and therefore the chocolate
manufactured there has an exquisitely
fine aroma,
SUMMARY.
_ The fermentation process itself is due
in the first place to yeast cells which
multiply rapidly in the saccharine juice
oozing fromthe pulped cacao and produce
alcohol and carbon dioxid. In the second
place bacteria participate, which develop
rapidly after a certain time, and change
the alcohol formed by the yeast by
oxidation, either wholly or partly, into
acetic acid. These processes cause a
rise of temperature and the death of
the cells of the seed and slime tissue,
whereupon the juice of the slime tissue,
more or less altered, collects at the
bottom of the receptacles, together with
the acetic acid produced.
The chief object of the fermentation is
to shrink the slime tissue or pulpat-
tached to the testa of the seed, allowing
the remnants either to be washed away,
as is doue in Ceylon, or dried upon
the seed forming an irregular brown
film upon the testa. The advantage of
thus changing the voluminous slime
tissue lies in the increased facility of
quickly drying the seed. In this regard
there exists a close analogy to the
fermentation of coffee. The loosening
of the adhesion between seed and its
envelope and the hardening of this
envelope (testa) are claimed as further
effects of fermentation.
_ The fermentation has also an indirect
influence on changes going on within the
seed, inasmuch as by the temperature
produced (40° to 50° C.) the cells of the
seed are killed, thus liberating the oxi-
dizing enzyms, which cause the forma-
tion of the brown colour, by oxidation
of the tannin of the seed. This brown
colouration is increased during the
drying process and finally by the
roasting. ;
The taste of the raw cacao bean is
not only altered by the partial oxidation
of tannin during the fermentation or
sundrying of the seed, but also by
products of roasting.
The action of oxidising enzyms, as
well as the final roasting process, play
a part in the development of the aroma,

A. B. C. OF LIME CULTIVATION,
(Continued from page 538.)
CROPS.
Generally speaking, the main flower-
ing period of the lime is from February
to June. Inthe rainy season, extending
from June to December, a week of fine
weather will often cause the lime trees
to put out afew clusters of flowers, and
it is from these minor flushes thata few
fruits are procurable all the year round.
The main-crop season extends, as a
general rule, from June to December.
Whether the main crop is early or late,
whether the bulk of the crop ripens in a
short period, say, from six to eight
weeks, or is prolonged over several
months, or whether there is an early
crop in July and August followed by a
distinct second crop in November and
December, depends chiefly on the local
weather conditions and on the vigour of
the trees.
Accurate observations of the length of
time from flowering to the maturity of
the lime fruit do not appear to have
been made, but itis usually placed at
five months. It depends upon the local
climatic conditions and upon the vigour
of the trees.
The yield per acre of fully established
lime estates varies greatly. Good estate
cultivation should produce from 150 to
160 barrels of fruit per acre annually,
but there ismuch cultivation that does
not yield higher than from 80 to 100
barrels of fruit per acre. A barrel of
limes gives from 73 to 8 gallons of juice,
but the acidity of the juice varies
according to the rainfall. An estate
with a low rainfall may average 14 oz,
citric acid per gallon of juice, while
another with a higher rainfall may
average 120z. In the very wet districts
in the hills the acidity is as low as 10 oz.
per gallon,
The yield per acre of a lime plantation
is sometimes expressed in barrels of fruit
and sometimes in hogsheads of concen-
trated juice. Neither conveys much
meaning unless accompanied by the
acidity of the raw or concentrated juice.
It: would be better expressed as pounds
of citric acid contained inthe concen-
trated juice, for it is evident that a
return of 200 barrels of lime per acre
viving juice testing 14 oz. per gallon is
very different to the same return per
acre in barrels giving juice testing 10 oz.
per gallon. Similarly with concentrated
juice, some estates concentrate to 100
[JANUARY, 1909,
oz. per gallon, others to 120 or 1380, and a
few to 140 to 150 oz. It will be seen that
there is a wide difference between hogs-
heads of concentrated juice testing 100
oz. per gallon and others testing 140 oz.
About eight-ninths of the lime juice
produced in Dominica is concentrated
for sale to citric acid makers ard to
cotton bleachers. The remaining one-
ninth is exported as raw lime juice for
making cordial. The establishment of a
citric factory in Dominica will tend
probably to reduce somewhat the pro-
portion of concentrated juice, for this
factory takes the juice after the
essential oil has been expressed and
before concentration in the usual course
is begun.
The standard at which concentrated
lime juice is sold is a pipe of 108 gallons
testing 64 oz. to the gallon. Its equi-
valent is a 52-gallon hogshead, the pack-
age used in the West Indies testing
133 oz, to the gallon.
Limes, when ripe, fall from the tree,
and are collected from the ground by
women and children into heaps. The
usual price paid for collecting the lime
is at the rate of 8d. per barrel, but this
rate is increased when they have to be
carried for long distances.
———————
The fruits are then put into carts and
taken to the mill house for the extrac-
tion of the juice.
MACHINERY REQUIRED, FURL, ETc.
Many of the old three-roller sugar
mills placed in position when sugar was
the staple crop are still in use to-day
for crushing limes. The sugar mill with
iron rollers adjusted to crush limes has
answered admirably where the lime
juice is concentrated. These are usually
driven by water power on large estates,
and in some instances by cattle. On
small estates, mills worked by hand
power are in use.

The machinery required for dealing
with lime juice consists of a three-roller
mill (iron rollers may be used where the
juice is concentrated, but they should be
of granite when raw juice is prepared
for shipment for making cordial) driven
by steam, water, or cattle; a press for
extracting any juice that may be left in

ware pipes. It should not be allowed to
come in contact with metal.
Works should be arranged so that the
mill house is on higher ground than the
boiling house. The juice on leaving the
mill then runs by gravitation to the
storage vats, from the vats to the still
and from the still to the copper tayches
where it is concentrated. It is then
placed in wooden or copper coolers, and
is finally run into hogsheads for ship-
ment.
Concentration of lime juice in copper
or wooden vessels fitted with steam coils
has been recommended, and would no
doubt be an improvement on the present
system. Itis not now likely that any
great effort will be made to improve the
present system of concentrating juice,
as the manufacture of concentrated juice
may subsequently be superseded by the
manufacture of citrate of lime.
The Dominica Planters’ Association
when furnishing information for the
revision of the pamphlet entitled Hints
to Intending Settlers, Dominica, wrote
that ‘for lime cuitivation a mill, mill
house, two tayches, battery, and boiling
house large enough for adequate storage
room would cost about £3800.” The
above estimate includes a small copper
still.

The above is the minimum for a begin-

works would need enlargement, and a
copper still and three tayches of a larger
size would be required.
The above plant could deal satis-
factorily with the crop produced from
10 to 12 acres, but would after about
the first two crops be quite insufficient
to deal with the produce of 50 to 60
acres.

In many of the West India Islands, old

less than the original cost, and the out-
lay may thus be reduced.
Most of the machinery on lime planta-
tions in Dominica is driven by water
power, but it is doubtful whether this
source of power will be made use of
on new plantations, except on those
that are particularly favourably situated
for its installation. In most situ-
ations, the cost of building an aqueduct
would be considerable, and the cost of
even a moderate-sized wheel would cer-
tainly be greater than for an oil engine
or equal horse-power.
It is thought that when circumstances
are favourable, a Pelton wheel would
probably be the cheapest form of power,
both in cost of installation and in cost
of running.

siderable quantities of fuel are required.

the juice) to boil down sufficient juice to
filla hogshead. On some estates fuel is
very scarce and costs from 8s. to 10s. a
eord. On others, wood is plentiful and
costs from 38s. to 4s. a cord.
When concentrated juice is selling at
normal prices, that is, from £12 to £12
10s. per hogshead testing 133 oz. to the
gallon, the cost of fuel together with the
cost of the packages and the high freight
that has to be paid on liquid produce
have to be seriously considered. The
industry under such conditions cannot
be said to be a particularly attractive
one. At present prices are high and
may remain so for several years.
On estates where fuel is scarce, it has
been recommended that several pieces
of quick-growing eucalyptus might be
planted in odd corners of the estates.
Edible Products.
These grow rapidly and ratoon well
when cut. Once established, they
would bear being cut over every two or
three years, while native trees that
have been cut down are not ready for
cutting again for at least ten years.
The fuel question is an important one
in the manufacture of concentrated juice,
and even if citrate of lime supersedes it,
the fuel question will remain. To make
citrate of lime, and todry it, will require
as much, probably more, fuel than the
present system of concentrating juice.
LIME PRODUCTS.
FRvITS : GREEN LIMEs.
The early shipments of green limes
from Dominica were made during 1891,
when 99 barrels of fruit were shipped.
From this small beginning, the present
considerable business in green limes
with New York and London has been
developed. The export of this fruit
during 1907 was 18,311 barrels, valued at
£6,409.
The American market demands a
small fruit packed in well ventilated
barrels, and the London market a large
fruit packed in small crates of a capa-
city of one cubic foot. A barrel holds
from 1,400 to 1,600 fruits varying accord-
ing to the size of the limes, and a crate
from 200 to 240.
Green limes are picked from the trees,
and are allowed to quail for several days
before they are packed. The lime, how-
ever, does not apparently require the
same degree of quailing as the orange
does to ensure its arrival on the market
in good order. Each fruit must be wrap-
ped in paper, and should be very _care-
fully packed, Very great care is_re-
quired in gathering, handling, wrapping,
and packing, to ensure the best results.
The lime is used for the same .purposes
asthe lemon. It iscertainly displacing
the lemon, to a considerable extent, in
the United States.
PIicKLED LIMES.
In Dominica a small business is done
in shipping limes pickled in sea water.
These limes gochiefly to Boston. The
trade is only a small one, and during late
years the export of pickled limes has
fallen off somewhat. This is probably
not due to a decreasing demand for
pickled limes, but rather to increasing
shipments of this product from other
West India Islands. The average annual
export of pickled limes from Dominica
for the five-year period ending 1896, was
1.505 casks, for a similar period ending
1901, 1,117 casks, and for five years
ending 1906, 1,000 casks. A cask holds
about 2,000 limes,
40
(JANUARY, 1909.
For pickling, the finest specimens of
sound yellow limes are selected and
placed in vats into which sea-water is
pumped.
In two or three days, this water is run
off and fresh sea-water pumped in. This
process is repeated several times until
the limes are cured. The fruit is then
placed in casks which are in turn filled
with sea-water to which a small amount
of salt has been added. The casks are
then closed, and are ready for export.
Raw LIME JUICE.
Lime juice intended for making cor-
dials and for flavouring confections
requires very caretul preparation.
The limes should be washed before
being crushed in mills fitted with granite
rollers. Only the first juice obtained
by lightly crushing the fruit through
the first rollers is used. The second
juice and the press juice which are
weaker in acid are used for concentra-
ting.
The first mill juice is carefully strained
and placed into puncheons when quite
fresh. Formerly it was run into vats,
and after settling the clear juice was
placed in puncheons or hogsheads for
export.
It is wellknown that raw juice care-
fully strained and placed in packages
when quite fresh will keepin good con-
dition tor a considerable time, but if lime
juice is exposed to the air it will gra-
dually lose its acidity.
The raw juice trade is in the hands of
two or three firms and _ probably dif-
ferent methods are employed in each
case.
CONCENTRATED LIME JUICE.
Limes are grown chiefly for the pro-
duction of citric acid only a small pro-
portion of the total crop being used for
lime juice cordials and for the green
lime trade. In the West Indies the juice
is concentrated in order to reduce bulk
before shipment to the citric acid
makers.
It is usual to reduce by boiling 600 gal-
lons of lime juice to 50 gallons of the
concentrated product. Some estates,
however, concentrate 10 to 1, others at
9 to 1, instead of 12 tol. Mven with low
concentration there is a considerable
loss of acid. When concentration is
carried on to 180 and 140 oz. to the gallon,
the loss of acid is very great,
Planters can now test their own lime
juice in the bci.ing house and thereby
suve a considerable destruction of citric
acid during concentration, by means of

for use in ascertaining the strengths of
solutions of citric acid and of lime juice
by means of a hydrometer will be found

method is described in the Agricultural
News (Vol. VI, p. 149.) The following
extracts are taken from these articles :—

Lime juice for concentration should,
when leaving the mill, be carefully
strained in order to remove all the seeds,
before it is run into vats. From the
vats it isrun into the still to obtain the
oil, and afterwards to the tachyes to be
concentrated.
It has lately been shown (West Indian
Bulletin, Vol. VIII, p. 171) that lime
juice, carefully strained, and then settled
after distillation has obtained a special
market, and commands higher prices
than ordinary concentrated juice.
Every effort, therefore, should be made
by planters to ship a high-class product,
6
Edible Products.
The juice is shipped to New York or
London in hogsheads of 52 gallons,
where it is tested and paid for according
to the citric acid contents.
Buyers in London and New York pay
for citric acid, and not for impurities in
the juice. The presence of the latter
causes great trouble to manufacturers
of citric acid, and tends to bring prices
down. Lime juice shouid therefore
never be concentrated in iron tayches,
as the iron combines with it and lowers
the value of the product.
Concentrated juice testing 100 to 105
oz. per gallon made of well strained and
carefully settled lime juice is a black
and heavy, but not a dense, liquid.
When no care is taken to strain or settle
the juice, the product is black, and as
thick as molasses at the same degree of
concentration.
CITRATE OF LIME.
In the manufacture of citrate of lime,
the juice on leaving the mill is carefully
strained, then distilled to obtain the
oil, and afterwards while still hot, it is
run into a wooden vat to be neutralized
with chalk. Before running into the
mixing vat, it would be an improve-
ment if the hot juice were passed
through filter bags. (West Indian Bul-
letin, Vol. VIII, p. 167). At present
lavigated chalk is imported, but it is
hoped later to use mainly lime made
locally from coral. It is generally stated
that the process of neutralization should
be finished with chalk, but one authority
has said that finishing with lime, even
when chalk has been used to start with,
is to be recommended as there is thereby
asaving of time and a clearer indication
isobtained. Neutralizing vats are fitted
with perforated steam coils in order to
keep the juice hot, and toactas agitators
during the time chalk is being added,
during the washing process, and until
the citrate is finally run into the filter
bags. They must be large enough to
prevent loss from overflow by the foam-
ing effervescence which takes place when
ehalk is added.
Dr. Watts writing on this matter
says :—
‘A sufficient quantity of chalk is made
into acream with water and the mixture
poured cautiously into the juice with
constant stirring, proceeding cautiously
as the acid is neutralised. To ascertain
how much chalk is to be used it is best
to proceed as follows: When the greater
part of the chalk has been added, the
mixture is well stitred and the efferve-
scence is allowed to subside; a small
quantity is then taken out and tested
by the addition of a little of the mixture
.Edible Products. 42
of chalk and water; if this produces
an effervescence, more chalk must be
added to the main quantity, proceeding
cautiously and testing intervals, until
no effervescence is produced. A further
test is now made—a little of the mixture
is withdrawn and heated; as soon as
bubbles of gas cease to be given off,
a few drops of acid (fresh lime juice
will answer) are added. This will pro-
duce a slight effervescence if chalk has
been added in right amount, and a brisk
effervescence if too much has been used.
In the latter case, more juice must be
added to the mixture and the process
of testing repeated.’
If you add too little chalk to your
lime juice, you lose someacid. Ifyou
add too much, it gives the manufacturer
trouble by wasting his sulphuric acid.
The buyers of citrate of lime have
determined to. penalize anything con-
taining an excess of over 2 per cent.
of chalk.
After neutralization, the citrate is
allowed to subside, and the mother
liquor is run off through a tap fitted
in the side of the vat. Hot water is
then run in and steam turned on to
thoroughly wash the citrate. The wash-
ing should be repeated several times,
the citrate being allowed to subside and
the water run off between each washing.
Finally it is agitated and run through
a lower cap into the filter bags to drain.
Afterwards, it is placed in a press to
extract as much moisture as possible,
and then at once conveyed to the drier.
Recent experiments by Dr. Watts
show that the use of centrifugals is to
be recommended for removing the water
from citrate in place of the press.
Citrate can conveniently be washed with
a small quantity of hot water while
in the centrifugals, and when the mois-
ture has been removed by them, it can
be dried, in a much shorter time.
When thoroughly dried, it should be
placed in aroom to cool before being
tightly packed in barrels, hogsheads,
or puncheons for export. It is very im-
portant thatthe citrate be thoroughly
dried. If this is not done, much acid
may be lost.
Citrate of lime when prepared in the
above manner is a white powder and
should contain about 64 per cent. of
citric acid.
Citrate of limeis twice as bulky as
concentrated lime juice, but it is not
expected that freight on citrate will be
higher than on concentrated juice, as
shipping companies give a preference to
the dry over the liquid produce,
wy
Ey
JANUARY, 1909.
_ The manufacture of citrate in Dominica
is as yet only in the experiment stage.
Probably many improvements will be
made in the process as time goes on.
At present the great requirement is a
drying machine that will dry citrate in
a few hours without any loss of acid.
The driers chiefly in use now are modelled
on the cacao drier described in the
West Indian Bulletin (Vol. II, p. 178).
The process inthis class of drier takes
too long. and the consumption of fuel is
too great, for the most economical pro-
duction of citrate. If centrifugals were
generally adopted and an improved
drier brought in use, the manufacture of
citrate of lime on large estates would be
considerably simplified.
(To be continued.)
SWEET POTATOES.
(Continued from p. 548.)
BEDDING THE SEED.
in the warmer portions of the sweet-
potato-growing district the seed should
be bedded when danger of frost has
passed. In the northern portion of the
area the seed should be placed in the
hotbed from the 20th of March to the
10th of April, after the temperature of
the bed has fallen to 80° or 85° F. and ~~
become regular,
If possible, select a warm,
day for this work, in order that the
seed potatoes and the bed may not
become chilled. The soil to be used for
covering the potatoes should be sifted
beforehand and placed in piles in the
bed, where it will have become warm
and in good condition for use. Leaf
mould is perhaps the best material with °
which to cover the potatoes, but where
this cannot he obtained a fine, rich,
sandy loam is the best substitute.
Before placing the seed in the bed, an
inch or more of the finely sifted covering
material should he spread evenly over
the surface of the regular soil in the
bed, The potatoes are spread upon this
bed, each one being placed by hand so
that they will not touch, and about one-
half of the bed surface is covered. If
extra large potatoes are employed for
seed they may be split lengthwise and
placed with the cut side down in the
bed. When the potatoes are in place,
cover them to a depth of about 3 inches,
water by using a sprinkling can, and
then watch the temperature of the bed
carefully until the potatees have formed
an abundance of sprouts.

JANUARY, 1909. |
TEMPERATURE OL THE PLANT BEp.
As noted above, the temperature of
the plant bed should be about 80” or 85° F.
at the time the seed is bedded, and
should gradually fall until it remains
stationary at 58° or 60° Ff. at the end of
six weeks, or before planting-out time.
A thermometer should be kept plunged
in the soilof the bed and the temper-
ature noted every day for the first ten
days or two weeks. If the manure
hotbed is not located ina well-drained
situation there is danger of soil water
getting in with the manure and either
destroying the heat altogether or start-
ing asecond fermentation which will
cause the temperature to run too high
and injure the potatoes. The air tem-
perature beneath the sash or other
covering should run between 60° and
80° F., and during bright days it must
be controlled by ventilation. As the
time for planting in the field or garden
draws near, the plants should be given
more exposure to harden them _ to
outdoor conditions.
MOISTURE REQUIREMENTS OF THE
PLANT BED.
The amount of water required by the
plant bed will depend somewhat upon
the method of heating employed. With
a steam-heated or furnace-heated bed
more watering will be necessary than if
the ordinary manure hotbed is used.
The watering given when the potatoes
are bedded will generally be sutficient
to last for several days, but after the
plants begin to form leaves and the
cover is left off during the greater part
of the day, watering will be necessary
every day. The water should never be
poured on in a solid stream, but by
means of a sprinkling can or a rose, or
nozzle, on the end of a hose. Where
very large plant beds are employed it
will be necessary to keep some one in
almost constant attendance to care for
the watering, heating, and ventilation.
The success of the crop depends largely
upon the character of the plants, and
proper management of the plant bed is
essential to the production of the right
kinds of plants.
“DRAWING” THE SETS.
‘““ As a general rulesweet potato plants
are set in the field shortly after a rain.
In order to avoid delay in planting, the
hands should begin to get out the
sets as soonas the rain ceases falling
and place them iu crates or baskets
ready for transportation to the field.
The sets are not all produced at once,
and only those that have formed good
roots are ‘drawn,’ the others being
left until later. In‘ drawing’ the sets
the seed potato is held down with the
45
Edible Products,
one hand while the plants are removed
with the thumb and finger of the other
hand. It often happens that five or six
plants will cling together at the base,
and these should be separated in order
to avoid loss of timein the field. Where
plants are to be set with a transplanting
machine it is essential that they should
be in the best possible shape in order
that they may be handled rapidly by
the boys who feed the plants into the
machine. The roots should all be kept
in one direction, and if the tops are
long orirregular they may be trimmed
off even by means of a knife.”
While ‘‘ drawing” the sets it is a good
plan to have at hand a large pail or
a tub containing water to which there
has been added a quantity of clay and
cow manure which has been stirred until
it forms a thin slime. As the plants are
pulled from the bed they are taken in
small bunches and their roots dipped
into this mixture. This process, termed
*“puddling,” covers the roots with a
coating which not only prevents their
becoming dry in handling but ensures
a direct contact with the soil when
they are planted in the field or garden.
After removing the sets that are ready,
the bed should be watered to settle the
soil where it has become disturbed and
then left for the younger plants to
develop.
PACKING PLANTS FOR SHIPMENT.
In preparing sweet potato plants for
shipment or for sale, they are ‘“‘ drawn”
from the bed and tied in bunches of 100
each with soft string. Sweet potato
plants will not withstand excessive
moisture and should always be packed
while the tops aredry. A little damp
moss or paper may be placed in the
crate or basket and the roots bedded
in it, but the tops should remain dry
and have free ventilation. Ifthe roots
of sweet potato plants are carefully
puddled without the mixture coming
in contact with the tops, they will keep
in good condition for a week or ten days.
PREPARATION OF LAND FOR SWEET
POTATOES.
The character of soil devoted to sweet
potato culture is generally quite easy
to prepare. In preparing land for plant-
ing sweet potatoes the plowing and
fitting are practically the same as for
corn. It should be borne in mind,
however, that the work necessary for
thorough preparation will be well repaid
by the increased ease in handling the
crop later. It is always desirable that
a crop like sweet potatoes be grown
as a part of‘the regular farm rotation.
In the northern portion of the sweet-
Hdible Products.
potato-growing area the crop will occupy
the land the entire growing seasons,
and a three or four year rotation should
be practised. Where the climate will
permit, a crop of early snap beans, peas,
or cabbage may precede the sweet pota-
toes, but in many case the land should
not be planted to sweet potatoes oftener
than onee every three vears. A good
rotation is to devote the land to corn
one year. sowing crimson clover in the
alleys between the rows at the time
the corn is given the last cultivation.
During the following spring the crimson
clover should be turned under and
sweet potatoes planted; then in the
autumn, after the potatoes are harvested,
the land may be plowed, fitted, and
sown to rye or winter oats with plenty
of grassseed. In this way, crop of grain
may be obtained during the time that
the grass is becoming established. Allow
the land to remain in grass one or two
years and then repeat the rotation.
Where cornis followed by sweet potatoes
in the rotation, stable manure should
be applied while fitting the land for
the corn, and commercial fertlizers
should be applied with the sweet potato
orop.
As previously mentioned, the depth
of plowing.has considerable influence
upon the character of the product.
The usual depth of plowing in preparing
land for corn will prove satisfactory for
sweet potatoes. The tact that sweet
potatoes are not planted in the field until
quite late in the spring makes it possible
for the grower to select a time when con-
ditions are favourable for the prepara-
tion of the land. Plowing may be defer-
red until the soil has become sufficiently
dry to break up fine and mellow. It is
important that the land should be har-
rowed within a few hours after plowing ;
further fitting may be deferred until
later, and if the soil is inclined to be
lumpy the work of pulverizing may best
be done shortly after a shower and while
the lumps are mellow. When the pri-
mary work of preparation is finished,
the soil should be mellow to a depth of
6 or 7 inches and the surface smooth and
even. Subsequent handling of the soil
preparatory to_ planting will depend
upon whether ridge or level culture is to
be followed.
APPLICATION OF FERTILIZERS.
" For the general good of the land com-
mercial fertilizers should be applied
broadcast, but the majority of farmers
feel that they cannot afford to do this
and that the quantity that they are
able to apply ‘will give greater returns
when placed in therow. Thisisa matter
for the decision of each grower and will
[ JANUARY, 1909;
depend greatly upon the capacity of the
soil under consideration for retaining
fertilizers from year to year.
PREPARATION FOR PLANTING.
_ After plowing and fitting the land it
is generally allowed to lie several days
before being put up in shape for planting.
If level culture is to be practised,
the only thing necessary will be to
run the harrow over the _ soil once
and then mark in both directions at
the desired distances for planting.
The marking is generally done with
either a one-horse plow, a_ flat-soled
marker. or a disk marker. The disk
marker is well adapted to this work,
as it throws up a slight ridge which fur-
nishes fresh earth in which to plant.
Some growers who practise level culture
mark the ground with a small one-horse
plow and throw up a slight ridge upon
which to plant; behind the plow a roller
is used to compress this ridge to a low,
flat elevation.
Where the more universal ridge method
of planting is employed the soil is thrown
up by means of a turning plow or a disk
machine. The ridges should be made at
least one week or before planting, in
order that the soil may become settled
and compact. The majority of sweet-
potato growers make the ridges when-
ever the land is in good condition to
work and then either roll or drag the
tops just ahead of the planters. By
using a roller the ridges at one operation
can be rolled and marked the proper
distances for planting. A drag suitable
for smoothing the tops of the ridges can
be easily constructed by cleating together
three pieces of 2 by 4 inch scantling.
SETTING THE PLANTS.
The success of the crop depends largely
upon the way in which the plants start
after being removed from the bed and
set in the field or garden. Practical
growers always plan to set the plants
during a ‘“‘season” or period when the
conditions are suitable to a quick start
into growth, either just before a rain or
as soon afterward as the soil can be
worked. The method of setting will de-
pend entirely upon local conditions and
the acreage to be grown, the essential
features, however, being to get the roots
in contact with moist earth and the soil
firmly pressed about the plants.
The use of water around the roots of
the plants is desirable under most cir-
cumstances, as it not only moistens the
soil but assists in settling it about the
roots. A large quantity of water is not
necessary, one-half pint to each plant
being generally considered sufficient.
sien)
JANUARY, 1909.!
DISTANCES TO PLANT.
Where level culture is practised, the
plants are set from 24 to 30 inches apart
in each direction. On the eastern shore
of Virginia the greater portion of the
crop is planted 24 inches apart each
way, requiring about 11,000 plants to an
acre. By planting 30 inches apart each
way, only about 7,000 plants are required
to set one acre. Where the crop is
grown on ridges it is customary to have
the ridges from 36 to 42 inches apart
from centre to centre and to place the
plants 14 to 18 inches apart in the row.
By this method an acre will require
from 8,000 to 12,500 plants. An acre of
good sweet potato land will readily
support 9,000 to 11,000 plants, and the
number most commonly planted by the
several methods will fall within these
figures,
When planting for level culture the
location of the plants will be indicated
by cross marks, but for planting upon
ridges itis necessary to provide some
means of indicating the distances. This
may be accomplished in severel ways,
but a roller hafing cleats nailed at equal
distances around its surface is desirable
and serves the purpose of both rolling
and marking the ridges. Another
device is contructed along lines similar
to those of the ordinary wheelbarrow,
pegs being placed upon the rim of the
wheel to mark the planting distances.
In using the wheelbarrow marker it is
simply pushed along the top of the ridge.
Another device of this class is con-
structed by placing three or four wheels
upon along axle and drawing it witha
horse, the wheels being so arranged
that they can be set at any point on the
axle to provide for change in width
of row.
A very cheap and efficient can marker
be constructed of 1 by 38 inch laths.
This marker can be used to indicate
planting distances along one row, or by
dragging it across the ridges the entire
field can be marked before beginning to
plant. The machine transplanters are
provided with a spacing device which
indicates the distance between plants;
also with a row marker to show the
location of the next row.
SETTING By HAND.
Where a few hundred plants are to be
grown for home use orif only an acre
or two are to be planted, the hand
method of planting will answer every
requirement. A trowel or a dibble is
used for opening the soil to receive the
plant, and the earth is closed about the
roots by a second thrust with the imple-
ment, or the heel of the shoe is used _ to
press the earth about the plant. For
Edible Products.
hand planting, the plants are dropped
ahead of the ‘‘dibblers” by boys and
girls. Seven thousand to ten thousand
plants, or an acre, is an excellent day’s
work fora planter when everything is
in good condition. Where a few
hundred plants are set in the garden it
is always desirable to water them before
closing the earth about the plant.
PLANTING WITH TONGS.
Setting by hand is at best a back-break-
ing process, and numerous devices have
been invented to save the bending of
the body in hand planting. One of the
simplest of these is a pair of wooden
tongs with which the plant can be
caught by the root and thrust intothe
soil. The plants are either dropped
ahead or carried in a small basket
strapped to the waist of the operator.
The tongs are provided with a spring
to throw the jaws apart, and are held
in one hand while the plants are inserted
with the other hand. In case the plants
are dropped ahead, the root portion is
grasped between the points of the tongs
without the use of the hand.
An implement, known as a shovel,
which is sometimes used in conjunction
with the tongs, consists of a piece of
lath sharpened toa flat point. This is
used toopen a hole in the soil ready
for the plant. In using the tongs and
shovel, the plants are dropped as for
hand planting. The person doing the
setting carries the tongs in the left
hand and the shovel in the right. The
plants are picked up by means of the
tongs, while a hole is made by inserting
the shovel in the soil at the point where
the plant is to be set. The plant is then
inserted and the earth closed about it
either by a second thrust of the shovel
or by the foot of the operator. A man
who is expert in the use of these home-
made tools can set plants quite rapidly
without bending the body sufficiently
for the work to become tiresome.
A tool that is sometimes employed
where vine cuttings are planted is a
long dibble ora cane havinga notch
covered with cloth or leather in the
lowerend. The droppers lay the cuttings
across the row atthe proper distances
and the planters place the notch over
the middle of the cutting and force it
jato the soil with both ends protruding.
SETTING WITH MACHINES.
Where a large acreage is grown, the
work of setting the plants in the field is
greatly facilitated by the use of trans-
planting machines, of which there are

as the machine automatically throws
a small quantity of water around the
roots of each plant as it is being set. In
operating these machines it is necessary
to have a steady team and two active
boys who are trained to drop the plants
at proper intervals, as indicated by a
spacer on the machine. Under reason-
ably favorable conditions, a machine
will plant from 38 to4 acres a day. In
addition to being labor savers, these
machines do the work better and more
ery, than itis ordinarily done by
aand.
The plants can be set without the use
of water, but the results are more satis-
factory where the water is used. A
number of our most successful growers
use water when setting after a rain,
claiming that the water has the effect
of settling the soil firmly about the
roots of the plants and that they
start into growth much more quickly.
Where the full amount of water is
used it will be necessary to provide
aman and team to hold the water to
the machine, but by this method plants
may be set during dry weather without
the loss of more than one plant out ot
every one hundred.
The majority of the transplanting
machines are designed for planting either
on the tops of ridges or on the level.
The cost of setting an acre with one of
these machines, using water, should be
figured on the basis of two teams with
drivers and two boys for a period of
three or three and one-half hours. If
water is not used there will bea saving
of at least one team and driver; also the
time required for filling the tank on the
machine.
CULTIVATION OF SWEET POTATORS.
The methods of handling a crop of
sweet potatoes do not differ materially
from those employed with ordinary farm
and garden crops. Within a few days
after planting, a sweep or onehorse plow
should be run in the alleys to break
out the strip of earth left in ridging,
The loose earth in the alleys should
be worked toward the rows until a
broad, flat ridge is formed upon
which a small-tooth cultivator can be:
run quite close to the plant. After
each rain or irrigation the soil should
receive a shallow cultivation, and during
dry weather frequent’ cultivations
are necessary in order to retain mois-
ture. About two hand hoeings are
generally necessary in order to keep the
rows free from weeds and the soil loose

around the plants. As hand labour is ex-
pensive, it should be the aim to perform
the greater part of the work by means
of horse tools. Where sweet potatoes
are planted in check rows and worked
in both directions the hand work re-
quired will be reduced to a minimum,
but a certain amount of hoeing is always
necessary.
When the vines begin to interfere
with further cultivation the crop may
be “laid by,” 7.e., given a final working
in which the soilis drawn well up over
the ridges and the vines then allowed to
take full possession of the land. Todo
this it is often necessary to turn the
vines first to one side of the row and
then to the other by means of a stick or
a wooden rake. After “laying by,”
very little attention is required until
time for harvesting the crop. ;
Toots ADAPTED TO SWEET POTATO
CULTIVATION.
Aside from planting and harvesting,
the work of caring for a crop of sweet
potatoes can be done almost entirely by
the use of ordinary fapm and garden
tools. A two-horse riding cultivator is
desirable for the general cultivation,
and one having disks instead of hoes
will serve for throwing the soil toward
the rows. For the work of “ laying by.”
a single-row celery hiller is suitable or a
one-horse sweep-stock can be fitted with
sloping boards and used for this purpose.
Many growers use a small one-horse tur-
ning plow for the final cultivation,
going twice in each alley and working
the soil toward the plants.

CITRATE OF LIME AND CONCEN-
TRATED LIME JUICE,
Dr. Watts, Government Chemist and
Superintendent of Agriculture for the
Leeward Islands, briefly reviewed the
position of the Lime Juice Industries of
Dominica and Montserrat :—
During the past year little additional
nformation had been obtained and
reference should be made to the article
prepared for the last West Indian
Agricultural Conference and published
in the West Indian Bulletin, Vol. VIII.,
pp. 167-9.
Concentrated juice prepared from
lime juice that has been carefully
strained and then settled, after distilla-
tion, has obtained a special market for
direct use in various arts and manu-
factures in the place of crystallized citric
acid. It commands relatively higher
'
JANUARY, 1909.] 47
prices than ordinary concentrated juice,
and therefore every effort should be
made by planters to ship a high-class
product.
The use of centrifugals in drying
citrate had given very good results.
Centrifugal-dried citrate contained much
less water than the ordinary pressed
product, and was in a better physical
condition. Samples of different types
of citrate now exhibited show clearly
the better condition of the centrifugal
dried citrate, and would indicate when
citrate of ‘lime is made on a large scale
the use of the centrifugal instead of
the ordinary process is to be recom-
mended.
Mr. Joseph Jones, Curator of the
Botanic Station, Dominica, gave the
following information in respect to the
progress made in the manufacture of
citrate of lime in Dominica during the
past year :—
During 1906, the year in which citrate
of lime was first exported from Dominica,
728 ewt. of this product was exported,
During 1907, 2,388 cwt. of citrate of lime
was shipped, showing an increase over
the export of 1906 of 1,660 cwt., a very
satisfactory advance.
Up to the present time only one firm
has been engaged in making this product,
but it is probable that another estate
may shortly commence its manufacture.
The great drawback in making citrate
in Dominica at present is the cost of
drying the product. What is required
is efficient machinery for cheaply and
quickly drying the citrate withont loss
of acid. When such an apparatus can
be obtained without too great a cost,
the chief obstacle in the making of
citrate of lime by estates will have
been removed,
Should such machinery be of too costly
a character for estates making 80 to
100 hogsheads of concentrated juice to
instal, then we may expect to see the
development of factories at suitable
points in the several districts for the
purchase of lime juice from adjoining
estates to be made into citrate of lime.
Information as to the cultivation of
the lime and to the manufacture of its
products has been prepared in co-oper-
ation with the scientific officers on the
staff of the Imperial Department of
Agriculture, and will shortly be issued
in pamphlet form.*— West Indian Bul-

THE IMPROVEMENT OF CACAO
PLANTING IN THE WEST INDIKS.
By J. H: HART, F.L.S.,
Superintendent, Royal Botanic Gard ens,
Trinidad.
Cacao estates in Trinidad are largely
planted on what is known as the con-
tract system. Under this system the
proprietor gives out certain areas toa
contractor, and after the land has been
cleared at the expense of the owner, the
contractor enters into possession for
usually about five years. During this
time the contractor drains the land and
grows certain crops for his own benefit,
and at the same time plants cacao as
laid down by contract. When the
lands are taken over by the owner from
the contractor, 1s. tols. 3d. is paid for
each full bearing tree, half that price
for each half tree, and a quarter for
each quarter tree.
The general adoption of this system
appears to depend upon the fact that
under it less immediate expenditure of
capital is incurred, and. the planter
when he has paid for the trees at the
end of the term, should immediately
obtain some return for his money, for
many of the trees should be commencing
to bear, Briefly, the proprietor gives
the land for five years for the cultivation
of food products, with some few restric-
tions, in return for the labour expended
in planting and rearing the cacao trees
with addition of a bonus per tree at the
end of the term.
In Tobago, the contract system is not
generally adopted, and some estates are
formed by the owners, There is but
little difference to be noticed between
aun estate planted under contract, and
one planted by an owner. The actual
method of planting under both systems
is identical; the same class of tree is
planted, the same shade is used, and the
same technic is adopted in both cases.
The methods pursued in other places
vary somewhat from those described,
but are in principal fairly identical.
There is no reasonable doubt that
although the contract system may have
its advantage as affording a cheap
means of establishing a plantation, it is
not one which provides for the scientific
treatment of ‘the cacao tree, as it is
based entirely upon growth from seed.
The cacao tree grown from seed varies
in vigour and _ productiveness, and in
size, colour, and flavour of its produce.
The seed of red pods may produce trees
bearing yellow ones, and those from
yellow may produce trees possessing red
Edible Products.
ones. In the seed itself there is great
variation in size, colour, flavour, and
number of seeds to a pod,
These variations, left to themselves,
are (following the accepted doctrines of
our best botanists) sure to tend toward
deterioration; but properly guided they
afford the means of not only maintaining
a standard but of improving. that
standard in any desired direction.
At the present time Trinidad cacao
is an interminable mixture of various
types near to, and far from, the original
strains. The better types prevail where
a preponderance of the better kinds
were first planted, aud the poorer types
in those districts where numbers of in-
ferior strains are present.
It would appear that there is little
cacao true to the original types of old
authors, and although the various
strains can be recognized, it is much
more easy to notice the variation that
has occurred, even during the last two
decades. Trinidad Criollo can still be
recognized generally, but the bottle
neck of that variety is now to be seen
plainly marked in varieties where the
Forastero strain predominates. The
Venezuelan Criollo may be seen ap-
parently true in form and colour with
the accepted type, but on examination
shows that the plants may have coloured
instead of white beans,
I suggested in 1897, thatit was urgently
necessary when raising from seed, to be
extremely careful in selecting from the
very best trees, but 1am now quite con-
vinced that. this method, while being
better than no selection at all, is quite in-
sufficient to secure the highest class of
produce, and that vegetative production
by budding or grafting must be adopted
if cacao is to be improved along scienti-
fic lines. In 1897, it was not certain
‘that budding or grafting was practi-
cable with cacao, but it has since been
proved that they may easily be per-
formed. Recently I prepared an article
on cacao improvement that was pub-
lished in the Trinidad Bulletin, Vol.
VII., p. 183. In this was described in
detail the method necessary for the
improvement of plantations.
The principle points are (1) the entire
abandonment of propagation from seed
except for the purpose of raising new
and improved varieties, (2) improvement
by the aid of hybridization or seminal
variation, (8) the selection of standard
varieties trom present fields showing
desired characters in order to propagate
from them by grafting or budding, and
(4) the characters to be used in making
48
[JANUARY, 1909.
the selection should be high vitality,
good bearing qualities, good habit and
form, and a high quality of produce.
At the Conference held at Trinidad in
1905, I presented a paper on the special
qualities of plants. In it I presented
arguments to show that special qualities
are inherent in each and every indivi-
dual plant, which remain constant
through its life and may be propagated
indefinitely for centuries ; and 1am more
than ever confident that if these views
are brought into practice in the working
economy of cacao estates, a very great
improvement in the quantity and
quality of the produce obtained would
rapidly follow. One treein the Botan-
nical Department, Trinidad, produced
in 1907, 15 lb. 9 oz. of marketable cacao,
and it would appear desirable that such
a tree should be among the selected
varieties to be reproduced by vegetative
reproduction.
In cacao plantations there are trees of
a high class, and also many of an inferior
type. The latter, being as a rule ot
greater vegetative vigour, tend to domi-
nate, and gradually may push out the
better strains. In the following gener-
ations, when again reproduced by seed,
deterioration necessarily occurs and a
large number of interbred varieties is
produced.
It is satisfactory, however, to note
that not a few planters are alive to this
danger of deterioration in quality, and
have imported of the best strains
from the mainland of South America.
Even these show considerable variation.
These importations, nevertheless, are of
superior quality, and they must have an
effect, though a limited one, inimproving
the standard quality of Trinidad cacao,
The improvement can ouly be a tran-
sient one, as the inferior kinds, being
the more vigorous, and inthe majority,
will again, in time, dominate the better
qualities. lf, however, selections are
made of the most distinct forms, and
these are propagated solely by vegeta-
tive reproduction, the improvement
would most assuredly be a permanent
one, and when once standard and
selected kinds are propagated by this
method alone, and not by seed, deteri-
oration would cease, and no change in
the quality of produce could occur,
except that induced by unfavourable
weather, accidents during curing, or by
unfavourable situations.
Trinidad cacao has obtained a name
for certain good qualities, but manu-
facturers cannot use Trinidad cacao
alone. They require other and often
higher-priced qualities to mix with it
JANUARY, 1909.}
to obtain the eecessary blends. The
average grower may be content with his
returns, but why should not West
Indies, with her excellent facilities for
growing cacao, be possesed of and grow
all the various kinds needed by the
manufacturer to make the required
blends, for the production of high-class
chocolate and cocoa? Or why should
not the West Indies possess sufficient of
each kind to be able to start successfully
the local manufacture of various cacao
products?
. It cannot be done to-day, because
several of the special qualities necessary
for making the flavours now recognized,
and demanded, are absent from West
Indian cultivation. Therefore it is
important to encourage the introduc-
tion of plants of all the foreign cacaos
which are necessary for the preparation
of the manufacturers’ blends. They
should be kept pure by. reproduction
solely by budding and grafting.
The West Indies would then be able to
put into the hands of the manufacturer
all that he needs in the way of qualities.
It may be said that prices of Trinidad
cacao are at present satisfactory. But
will they always be so? Every endea-
vour should be made to take advan-
tage of every improvement to raise the
quality of cacao, as in years of bad prices
it is well known that certain brands sell
at higher rates than others, because the
manufacturers require them, and that in
general a pure brand or well-known
mark is accepted at higher prices than
ordinary mixed strains. Thereis nothing
to be said against a grower who wishes
and prefers to grow alow-grade cacao,
but it is fairly clear that his returns will
not equal those obtained by the growers
of high-class produce, and even these
will fetch more if kept pure by vegeta-
tive reproduction, as they can be better
relied on for strength and evenness of
quality.
The question of the production of high-
class cacao of the various market quali-
ties appears to be a very desirable one;
and should be the aim of cultivators who
wish to attain to a high standard.
DISCUSSION.
THE PRESIDENT: I am glad to take
advantage of this opportunity of ex-
pressing the general fesling in the West
Indies in regard to Mr. Hart’s long
and useful career in connection with
agriculture. Mr. Hart spent the earlier
years in Jamaica where he was connected
with my Department there. He has
since been in Trinidad, and there can be
no doubt whatever as regards the earn
estness and thoroughness with which he

has carried on his work. Iam very glad
of this opportunity of putting that on
record, and also of thanking him for this
very useful, and, I think, very suggestive
paper which he has presented before the
Conference to-day.— West Indian Bul-
letm, Vol. IX., No. 2,
THE CHARACTERS OF CRIOLLO
CACAO.
By J. H. HART, F.LS.,
Superintendent, Royal Botanic Gardens,
Trinidad.
Criollo cacao, as represented by the
specimens exhibited, may be divided
into three sections: (1) 'Trinidad Criollo,
@) Venezuelan Criollo, and (8) Nicaraguan
Jriollo,
Trinidad Criollo is supposed to be
indigenous to Trinidad. The specimens
exhibited are the produce of trees grown
from pods selected by G. Kernaham,
Esqr., taken from original forest in the
district sf Manzanilla, Trinidad. Some
of the pods were yellow, and some red,
It has been found that seeds from yellow
pods are able to produce trees bearing
red pods, while those from the red pods
often produce trees bearing yellow pods.
The generally light colour of the beans
and their form are characteristic of the
variety, while the bottle-necked appear-
ance of the pods is a leading feature by
which they may be recognized. This
type of Criollo cacao is not quite as
vigorous as are the Forastero and
Calabacillo types, and though a fairly
good bearer, does not yield as well as
those kinds.
Venezuelan Criollo differs in form
from that of Trinidad, as the stalk end
is blunt and_ rounded instead of being
bottle-necked. The beans are larger in
size than those of Trinidad Criollo, and
differ somewhat in form: but like the
Trinidad kind, the beans when cut show
a white or nearly colourless interior.
Specimens of this kind of Criollo cacao
grown in Trinidad havebeen produced
from seed obtained from one of the best
Venezuelan estates, The produce shows
considerable variation both in outside
colour and form of the pods, as well as
in the colour of the beans. They are
not prolific bearers, but the quality of
the produce is of the highest class, and
estates possessing this strain can obtain
high prices.
This kind is also known under various
other names such as Caracas, Borborata,
etc., etc,
Edible Products. 5
The Nicaraguan Criollo differs some-
what from the Venezuelan in form of
ods. The size of the bean is also much
arger. The colour of the beanis white
and not so often shaded with colour as
the Venezuelan, and Trinidad Criollos.
The pods are rather more pointed in
form than the Venezuelan, but much
resemble them in other respects.
The beans produced by this kind are
probably the largest of any known
valiety of Theobroma cacao, and com-
pare very closely with those produced
by Theobroma pentagona, a species with
which it may have become hybridized
in Nicaragua. The bean of the Nicara-
guan Criollo, like that of Theobroma
pentagona, is, for its size, light in
weight. It possesses a flavour of very
high standard and takes_much less time
to cure than ordinary Trinidad cacao.
Propagated by grafting and kept pure,
this cacao promises to become a valuable
acquisition to West Indian plantations.
GENERAL REMARKS.
Grown as seedlings, these three
varieties are not heavy bearers and as
crop producers cannot be compared to
the stronger growing strains of Foras-
tero and some other varieties. All three
kinds possess valuable characters, and
it is highly probable that when grafted
on the stronger stocks, their yield would
be materially increased, and they would
become a valuable asset to the West
Indian cacao. planter.—West Indian
Bulletin, Vol. [X., No. 2.
ENSILAGE AND HOW TO MAKE IT
The preservation of fodder in the
shape of ensilage with all its succulent
prices retained, has been thoroughly
tested by so many practical men in
other countries that its value as a factor
in economical stock-keeping has been
proved beyond question, In Ceylon, so
far, the subject seems to be little under-
stood and, as far as I learn, nothing
practical has been done. To_ properly
appreciate the practical details of the
process it is necessary to understand
at least the outlines of the theory. We
aim at the preservation of green or
succulent fodder, and the more we can
diminish or prevent the changes which
such substances naturally undergo when
cut or gathered into heaps the better
will be the quality of our silage. To
do this effectively we have to learn
what these changes are, and how they
are brought about. Weknow that when
green fodder is cut and placed in a
heap it soon begins to heat and undergo
changes. This rise of temperature and
[JANUARY, 1909,
these changes are due to oxidation and
the presence of minute living organisms,
termed bacteria. These bacteria, fer-
ments, or microbes are everywhere
distributed in the atmosphere, endless
in variety and infinite in number,
Pasteur has shown that these ferments
or microbes require air in their first
generations or when their work begins,
but that afterwards they can go on
multiplying generation after generation
without air—that in fact fermentation
is directly the result of their breathing
the combined oxygen of certain organic
substances, such for example of sugar
in the absence of free Oxygen. When
the green herbage is placed in the silo
or stack

will be in contact with it or on it, and
in the free air in the spaces through-
out the mass. In the presence of this
free air they begin their multiplication
and work, but as we have seen the
work is continued and becomes more
manifest when the free oxygen among
the contents of the silo or stack has
been exhausted, unless in the mean-
time the germs have by a rise of
temperature been killed. It has been
found that a temperature of 120 deg.
Fahr, or thereabouts is sufficient to kill
these ferments, and it is desirable there-
fore that the temperature of every silo
or stack should exceed that range. If
it does not the organisms live on and
work on, and through their vital fune-
tions change valuable food stuffs and
produce acetic acid, the acid of vinegar,
buric acid, the acid which gives the
rancid flavour to butter, and lactic acid
or the acid of sour milk, The feeding
value of the silage is consequently
diminished in proportion to the degree
of this fermentation. When the fer-
mentation has been allowed to continue
in this manner, sour ensilage is the
result, and it has accordingly less fatten-
ing value than sweet silage although
it is valuable to the dairy farmer for
milk production. But there is another
cause of change in the cells of the
‘plants ensilaged, and it is that which
is believed to bring abdut the rise of
temperature. When the crop has been
cut and has begun to wilt, the cells
would appear to continue living, and
that for some time until through desica-
tion ov otherwise the contents cease
activity. While thus living their vital
functions are reversed, instead of absorb-
ing carbonic acid gas and giving out
oxygen—the normal function of plants
—they now absorb oxygen and give
off carbonic acid. This is known as
intercellular oxidation, and when the
herbage has been carted to the silo

or stack shortly after being cut, and
while the cells are still living, this
oxidation is the cause of the rise of
temperature. By means of it also the
starchy substances of the cells are
changed into sugar, and the sweet
flavour of sweet ensilage is the result.
When the cells continue living and
oxidation continues alcohol is formed
and the feeding value is accordingly
diminished. But when the heat evolved
by this process of oxidation has raised
the temperatureto 122° Fahr. the vitality
of the cells is destroyed, and further
oxidation accordingly ceases. There are
TWO WAYS OF STORING SILAGE,
in the stack and pit. The former has
the advantage of its cheapness, but
experience has shown that it is far
more difficult to handle and that the
results are not so good, while the waste
is great and that it requires pressure.
In the pit or silo it is much easeir to
regulate the temperature, and there is
far less waste while no pressure at all
is necessary. There are also two kinds
of ensilage made, the sweet and the
sour, the former for fattening and the
latter for milk production. For the
making of silage the crop must be cut
when there is the most sap at maturity.
This is best ascertained by experience
which agrees with the average of 75 per
cent. of moisture. A practice adopted
by many practical men is to take a
quantity of the grassin the hands and
twist it like arope so that if moisture
drops from it freely it is time for cut-
ting: Ifthecrop is not caught at the
right period there is aloss of nutritive
value in the silage in proportion to the
delay, for at this stage the assimilative
process of the plant has practically
ceased, and its energies are devoted to
the transference of the nutritive mate-
rial from the leaves and stems to the
seed. If cut too early and crop has too
much moisture it will be difficult to get
the temperature to rise sufficiently high.
The result would be as explained above,
that the fermenting germs will not be
killed and in conjunction with oxidation
ane nutritive value is greatly lessened.
MAKING SILAGE IN THE STACK,
the spot chosen must be One most con-
venient for stock to feed. The stack
should be as large and square as possible
otherwise there is much waste. Rapid
work for sour ensilage and slow tor
sweet, temperature from 80 to 90 degrees
for the former and 125 to 140 degrees
Fahr. for the latter. Ifsour ensilage is
being made and the temperature is
found to rise above 90 degrees the stack
must be stamped down until the tem-

perature is lowered. To test the tem-
perature from time to time a simple con-
trivance can be made. Ten feet length
of gas-piping with a steel point welded
on to it is driven into the stuff to any
depth and a small thermometer let
down by means of a string. If the tem-
perature is allowed to go too high the
silage becomes dark coloured, dry and
almost charred, but this contingency
can always be prevented by adding
further green stuff, or, if the stack is
finished, putting on weights. While
building the stack or filling the silo
great care should be exercised to have
the distribution even, not lumpy, and
to have the stuff wel trampled round
the sides. If this is not done the air
gets in round the walls, and here and
there well into the mass, and destruc-
tion follows accordingly. The bacteria
present originally and the cells of the
plants ensilaged will have been killed by
the high temperature, so that if the air
be allowed ready access thereafter a
fresh infection of microbes and fungi
is admitted, and decomposition more
or less results. Stacked silage has many
apparent attractions for a_ beginner
because of its supposed cheapness. Ex-
perience has proved that
THE PIT IS BETTER AND MORE ECO-
NOMICAL.
The waste in astack is very great. As
a rule the surface of a stack to the depth
of about a foot or more is rotted and
completely spoiled. This waste with the
annual cost of weighting down the stack
and then removing the weights, and
the considerable loss that comes subse-
quently from the exposed condition of
the stack are all which more than
compensate for the supposed cheapness
in the first instance of the stack itself.
For weighting stacks all sorts of mate-
rial can be used—stones, bags of earth,
kerosine tins filled with earth or con-
crete, logs of timber, etc., aiming at
about 200 lbs, per square yard. There
are also many mechanical devices con-
trived and used. If ensilage is to be
made in silos or pits the construction of
them should be on the highest land
available as there is less chance of soak.
age, a pit 15 by 15 feet will hold 50 tons
of silage. The pit must be bricked and
roofed over. The same principles apply
tomaking as in the case of stack, but
of course in an airtight silo it is
much easier to regulate temperature
and. thus either to make sour or sweet
as desired. It is much the best process
to chaff the stuff into the silo especially
heavy stuff like maize. Short grass
needs no chaffing. I made pit silage for
some years with maize and other crops

with the very best of results. With a
pit no pressure is necessary. Spread
the stuff evenly, taking the temperature
now and again. If temperature rises
cramp it down all over specially all
round the edges, and when the crop is
all in and the temperature is bound
to keep right, cover with some straw,
and in three months the result will be
first class ensilage.
CROPS FOR SILAGE.
Any vegetation that stock will eat
in its natural state will make good
ensilage, and it will be much improved
by the operation. It is said that cattle
assimilate silage better than they do
any other food, the reason being that
the change effected in the silo is nearly
or quite that which is brought about
in the first stomach of the cud-chewing
animal. Maize makes a specially good
silage and can be highly recommended.
As regards other material, experience
cau only show what other Ceylon crops
makes the best silage. In conclusion I
may sum up the whole process in the
following facts :—
(1). Appropriate crops combining suc-
culence and maturity.
(2) To harvest when the crop has
about 75 per cent. of moisture in its com-
position.
(8). The staking, or chaffing and
filling of the silo, to proceed sv that the
temperature of the material reaches 80
degrees and does not exceed 90 degrees

SUGAR IN INDIA.
Anything which can be done to encour-
age the sugar industry in India should
be welcome, for its progress is slow and
the enormous imports from Java show
no sign of falling off. In the Indian
Trade Journal particulars are given of
a process for utilizing the waste products °
of manufacture, the residue of the cane
after it has passed through the mill. At
present this is useless except when
dried for fuel, but it is said to have
qualities which make it valuable for
paper manufacturers. A Trinidad sugar
planter has invented a process by which
the crushed canes are converted into
paper pulp, and he is now working sugar
and paper mills in combination. The
new pulp is worth £5 per ton, and as
there is a general shortage of wood
fibre for paper-making the new product
commands a good sale. It issuggested
that experiments should be tried in
India whereby the waste products of
our sugar-mills could be utilised in the
manner described, Perhaps the Agri-
cultural Department may take up the
matter and obtain particulars of the
Trinidad process with a view to its
adoption in India.—Indian A griculturist,

PLANT SANITATION.
THEORY OF THE PARASITIC
CONTROL OF INSECT PESTS,
All who have recently discussed the
question of the possibility of controlling
insect pests by the use of parasitic or
predaceous insects or by fungous or
bacterial diseases, have failed to consider
the subject from a very important point
of view.
The conditions determining the life or
death of insects are much more com-
plicated than is usually appreciated,
and the individual factors in the problem
are far from independent. The correct
estimation of this interdependence of
the causes of death in insects is of
vital importancein this connection. The
efficiency of each factor is so influenced
by the efficiency of the others that the
elimination of one cause of death or the
addition of an entirely new natural
enemy will usually have but a slight
poet upon the rate of survival or none
at all.
The reproductive powers of most or-
ganic beings are very great. Were
not all creatures liable to die prema-
turely, that is, before they repro-
duced themselves, reproduction would of
necessity have been limited to two off-
spring from each pair. Whenever re-
production is at a more rapid rate itisa
prima facie evidence that the chance cf
premature destruction requires it and
the greater the reproductive power the
higher this normal death rate. Were
conditions otherwise, rapid extinction
or enormous increase would result, The
fact that species maintain themselves
for ages with the rate between the
birth rate and that of premature death
not varying anappreciated fraction of a
per cent. is very evident.
This balance between birth and death-
rates ismuch greater than the numerical
stability. For instance, in the case of a
species increasing a hundred fold in a
generation, an average disturbance of
only a hundredth part of a per cent. in
this ratio—.e,, if onthe average one more
individual inten thousand should come
to maturity—this would result in nearly
tripling the numbers of individuals
within a, hundred generations, and one
tenth of one per cent. augmentation—
e.g., if one more in a thousand should
survive—would be an increase in num-
bers amounting in the same period to
nearly fourteen thousand fold.
DISTURBING, CONTRIBUTING AND
EFFECTIVE HACTORS.
The various causes of death may be
classed into two groups; first, those
that des troy all insects in a certain con-
dition or position, irrespective of the
numbers present (for instance, frost,
which might kill the same proportion
whether there was but one to the acre
or a hundred thousand); and second,
those that are more and more efficient
as the numbers increase. This is true
in general of predaceous and parasitic
insects and of diseases. Causes of death
of first class will aid in maintaining the
balance in an insect tothe extent they
are uniform in their action, the regular-
ly recurring winter, for instance; but
are usually erratic and_ disturbing
rather than balancing. Those of the
second category, however, iall tend
towards balance and their efficiency is
attested by the approximate balance
maintained in nature. Probably in all
cases numerous parasites “and pre-
dators and other factors of this same
class contribute to form the controlling
environment of an injurious species,
and each factor has a different potenti-
ality. Those of the second category can
be further subdivided into two classes,
the contributory and the effective. In
the former class, the efficiency increases
with the increase of the host, but not in
a sufficient ratio to ever overtake it.
Thus with the host at one hundred per
acre it may destroy one third. at two
hundred four ninths, at four hundred
thirteen twenty-sevenths, etc., never
reaching fifty per cent. Any series that
does not ultimately pass the percentage
of normal death rate is incapable of
itself diminishing the numbers of its
host. Its only effect is inslowing down
the rate of increase until some effective
factor becomes operative or until a dis-
turbing factor like frost produces a
general destruction.
The effective class of factors is that in
which the ratio finally reaches one
hundred percent, Thus with the host
at one hundred per acre it may |destroy
say one half, at two hundred three
quarters, at four hundred, seven
eighths, ete.; finally reaching a fraction
so large that only those survive that
are necessary to maintain the species.
Every factor of this class has its
particular point of balance, One may
overtake the host at two hundred per
acre and another only at two million
Plant Sanitation.
per acre, but both be finally efficient,
Toamember of this class of checking
factors, Mr. Elwood Cooper, the former
Horticultural Commissioner of Cali-
fornia, would apply the term ‘“ the true
parasite,” and those alone he would
consider worthy of importation.
To determine at any time the status
of an insect we should have to know the
percentage of efficiency of each factor
under the existing numerical promi-
nence of the host, and in order to prog-
nosticate the future we should need to
know the ratio of increased or decreased
efficiency of each under the changed
numbers of the host.
None of these factors can ever be
determined with any greas degree of
accuracy because they are each involved
in as complicated a system of inter-rela-
tions and in many cases the efficiency
ot a check against any one insect is
profoundly influenced by the ups and
downs of numerous other insects that
serve as alternate hosts.
The complication of the subject indeed
is so great that accuracy even of obser-
vation will beimpossible, but the failure
to reckon with all the factors of the
problem will make conclusions of little
significance.
The inter-relation of factors may be of
the most complicated nature; for in-
stance, a parasite which of itself might
be wholly inefficient due to its slow
rate of reproduction as compared with
‘that of its host, might be rendered very
efficient by the co-operation of a con-
tributing factor which could only delay
the rate of increase.
It will thus be readily seen that the
efficiency of all these tactors working
together is neither the sum nor the
average of the potential efficiency of
each, though much nearer the latter
than the former. Many writers have
assumed that by adding anew parasite,
its efficiency was simply added to that
of others previously existing. This
supposition ic certainly far from the
theoretical conception of the inter-rela-
tions of species as presented above, and
has not been borne out in actual ex-
perience.
RELATION OF LIFE CYCLE oF Host.
Thus far the insect whose control is
sought is conceived of as existing in but
one condition. The growth and trans-
formation of insects add still further
complications to the subject. The
checks are not simultaneous in their
action, but at each stage in the progress
of its development the insect lives in a
different environment. The parasites,

for instance, that affect the egg will find
the next generation of eggs perhaps
more profoundly influenced by the
checks that have operated during the
remainder of the life of the insect than
anything they have accomplished, and
so perhaps with the checks operating at
any stage. apg, Ory pe Owe wey a is

WIND-BREAKS FOR ORANGE
GROVES IN PORTO RICO,
Orange cultivation is an industry of
considerable promise in Porto Rico, and
numbers of plantations are now being
set out. A pest which is causing a good
deal of trouble in the citrus groves is
the orange mussel scale (Lepidosaphes
beckii, (Mytilaspis citricola), and the 1907
Report of the Agricultural Experiment
Station of the island mentions that
xperiments are in progress to determine
he best methods of dealing with these
insects. Spraying with kerosene has
given fairly satisfactory results. It is
stated, too, that Porto Rican planters
now recognize that wind-breaks on the
wind-ward side of the citrus groves play
an important part in checking the
spread of the scales. The following
notes on this point are taken from the
report :—
Wind-breaks are divided into two
classes—permanentand temporary. Per-
manent wind-breaks are generally plan-
ted on the outer borders ot the groves,
while temporary wind-breaks are planted
between the rows of trees. There are
several plants which grow very quickly,
and afford good temporary wind pro-
tection, namely: bananas, sugar-cane.
pigeon peas, and the China berry or
Barbadoes lilac (Melia Azedarach). Tem-
porary wind-breaks should not remain
between the rows more than three years
and in the case of bananas a furrow
should be ploughed on each side, thus
preventing the roots from sapping the
soil around the orange trees.
For permanent wind-breaks at the
present time the mango seems to be the
best, but in setting out the young trees
they should be headed as low as possible.
Bamboo is also being planted, and if the
cuttings are set out during the rainy
season they start much quicker... These
should be planted close together, so as
to form a hedge.
When brush land is being cleared for
planting, it is advisable to leave a strip
of uncut timber 20 feet wide every 300 to
400 feet. The results obtained from
wind-breaks are very marked, certain
groves which were wind-swept and were
not growing at all having been brought
into excellent condition. In almost
every grove in the island marked im-
provements have been observed as the
result of planting wind-breaks. In
certain areas there may be found trees
producing from 1 to 2 boxes of fruit,
while trees not more than 50 to 70 feet
away, and of the same age as the former
but without wind protection are fre-
quently noticeable, which, from their
development, might not be more than
a year old. On the latter the branches
are blown to one side and covered with
scale. Trees protected from the wind
require less spraying, and the fruit is
free from scars.—Agricultural News,
Vol. VII., No. 165; August, 1908.
GREEN MANURING.
In India manuring is yetin its empiri-
cal stage. The science of manuring, its
mode of action, the improvements of
the methods available and the return to
the soiloft all that is taken from it are
not sufficieutly known. The use of
green manures might be especially re-
commended to the Indian agriculturist,
especially on account of his poverty.
Green manuring consists of growing
acrop of some sort, usually a legumi-
nous one, and ploughing it into the soil at
the time of flowering. Modern science
has up to now determined ten chemical
substances in plants, viz., carbon, hydro-
gen, oxygen, nitrogen, sulphur, pihos-
phorus, potassium, calcium, magnesium,
and iron, Of thesechemical ingredients,
nitrogen, with which organic matter is
closely associated, has been generally
recognised to be the most important.
The growing of leguminous plants be-
tween the lines of the staple crop has
been found conducive to the accumu-
lation in the soil of a sufficient store of
organic matter and nitrogen. Nitrogen
in its free form is largely presentin the
atmosphere ; but the plants have not
got the power to utilise it. The diffi-
culty is that they require a medium to
render nitrogen available to themselves.
An experienced agriculturist describes
the utility of leguminous crop in this
respect thus :—‘ First rains, lightenings
and other natural causes tend to unite
the free nitrogen with hydrogen, oxy-
gen and other substances and com-
pounds, which falling down along with
rain, enter the soil and mix with the
earth (technically called metallic bases )
and forms salts of nitric acid. Hence
the starvation of the plant for nitrogen
in the presence of plenty of free nitrogen
in the atmosphere. _ It requires a medi-
ator and a process before the nitrogen
can be of usein itsformation,......
Of the several thousands of natural
orders of plants, modern science has
determined that a certain natural order
Scientific Agriculture. 62
known as leguminous (Pulse order) has
the power of utilising the free nitrogen
of the atmosphere into its own consti-
tuents. This it does either directly by
making the free nitrogen unite with its
own substances or indirectly by making
it unite with other substances in the
air and then utilising it for its own
purpose.”
Green mauuring is not a new system
of manuring for India. It appears to
have existed in various parts of India
from very early times, though its
rationalistic explanation in the light
of agricultural chemistry was _ not
known. Itisthesame as what is known
as the “ Pachaithol valar” in Malabar,
Travancore and other places on the
West Coast. Leaves of certain kinds of
trees, such as Portia or Silanti (Thes-
phesa populnea), Erukku (Calopropis
gigantea) Mango ( Nanagifera indica.)
Avarum (Cassia agriculata) are in
these places commonly used as manure
for field crops. A few months prior to
the cultivation of the staple crop, horse
gram is usually grown in the fields
with a purpose to produce leaves to
get them ploughed into the soil. In the
case of the trees mentioned above, their
leaves are chopped and applied to the
soil soon after ploughing, in order that
they might mix with the earth and
decay. In some cases a few of the
staple plants are taken en masse from
the ground and in that spot cropped
leaves with mud are put in and over
this the plants are placed so that they
might strike root below in the manured
ground. Even leaves of ordinary jungle
trees are largely used as manure. Thus
it will be seen that our old farmers had
some idea about the utility of the appli-
cation of green leaves to the soil. They
knew that when some plants were
plouged into the soil or are simply raised
on it, the soil becomes exceedingly pro-
ductive. But it was only atthe end of
the last century that the German
chemist made some investigations on
the subject and discovered that these
leguminous plants develop certain nodu-
les at their roots which serve to accumu-
late millions of nitrifying bacteria.
This genus of plants known as legumi-
nose ( Pulse order ) were found to enrich
the soil in which they grew. They
have the peculiar power to absorb from
the atmosphere more nitrogen than
they require. They take just what they
want for their growth and leave the
surplus in the soil, In the above, we
have shown what “Green manuring ” is.
One of the important properties
of green manure is_ nitrification.
Besides . nitrification it has also other

properties. When the various parts
of these: leguminous plants get de-
composed and get mixed with the
soil the particles of the soil are made
to recede from one another, and as a
result the soil gets loosened. Thus these
green manures serve to assist in the
physical growth of the staple crop.
Again, the decomposition of vegetable
substances causes the evolution of car-
bonic acid. Plants, we know, are unable
to assimilate any substance except in
solution. Itis for this reason that water
is so necessary to plant life. The pre-
sence in the soil of carbonic acid or its
source in the form of decomposing plants
is highly useful for the healthy growth
of plants; for carbonic acid has the
property of dissolving various com-
pounds which are insoluble in water.
Side by side with these advantages, there
is, perhaps, one minor disadvantage.
The decomposition of organic substances
also causes the evolution of sulphurated
hydrogen, which is extremely injurious
to plant life. But the evil effects of
this gas might be considerably minimised
by turning up the earth more frequently
ee when other manurial agents are
used.
Various plants are used as green
manure. Which of them is best cannot
be definitely said. It largely depends
upon the nature of the soil and the
variety of the staplecrop. For instance,
horse gram, which is known to be a good
green manure, proves a failure when
tried on a crop of black gram. In a
lecture delivered by Mr. Herbert Wright
some time ago he mentioned the use of
Crotaralia striata, ground-nut, dadaps
and albizzia as green manures best suited
for tea plantation. They are found
equally useful in the case of coffee,
cocoa and rubber. There are other green
manures, such as mimsoa pudica, certain
varieties of cassias, tephrosia purpuera
and Sesbania Grandiigna, which might
be used with great advantage in coconut
and tobacco plantations. Mr. Wright
is a staunch advocate of ‘‘Green manur-
ing.” He believes ‘‘ that the growing ot
leguminous crops, besides enriching the
soil when dug in, keeps the temperature
of the soil more uniform in both the
damp and dry seasons, breaks the force
of rain and reduces the amount of wash,
prevents the loss of plant food by the
percolation of water and drainage, and
helps to keep the weeds in check.” Of
the green manures ‘mentioned above,
Crotalaria striata is not very commonly
used as green manure. The seed of
Crotalaria striata is sown broadeast and
the plants may be uprooted within six
or eight months after sowing. It yields
a large amount of a green organic

matter, giving over 6 tons per acre.
Six tons of green organic matter as
manure are equal to more than 100 lb.
castor cake. Its use as green manure
is confined to some Ceylon tea _ plant-
ations and on a small scale to some of
the tea districts in India. Groundnuts
have been found of greatest advantage
for the purposes of green manure. This
plant has a trailing habit. It does not
grow beyond a height of one foot and
it dies down in six months, It can thus
be dug in with the soil very easily.
Further, the cultivation of this plant
is very simple, the seeds being simply
thrown into the holes of an inch deep.
The one great advantage the ground-
nut thrown has over Crotalaria is its
small amount of tissue and its very
thin stems and leaves, which are readily
taken up by tea or other plants. It has
been found that ground-nuts provided
a large quantity of nitrogen, 9,000 Ib.
of the green material yielding as much
nitrogen as 1,500 lb. castor cake. The
Albizzia, which belongs to the genus
known as Albizzia moluccana, is not
much of a success asa green manure.
Crotalaria is much superior to _ the
Albizzia in the matter of the supply of
the organic matter, Of course, in the
absence of other green manures it may
be used in tea plantations. In addition
to those mentioned above, there are
a lot of other legumes. Cajanus indicus
(Dal) is a very useful plant that might
be profitably used asa green manure.
This plant, though not a native of
India, has become well acclimatized,
having been introduced into India from
tropical Africa some 3,000 years ago.
It can be cultiyated at a small cost.
With the beginning of the rainsit might
be sown, aid cut down as soon as the
crop begins to ripen. This plant is
known by various names. It is known
as Thovaray in the Malabar district on
the West Coast. There are many other
plants of the pulse order that might
be used as greenmanures. Experiments
are being made in the cultivation of
some of these plants as green manures
in the hope of discovering something
which do better than any of the above.
Thus far about green manuring and its
advantages. We shall now point out
another feature of green manuring.
Great care should be taken in the choice
of the plants for purposes of green
manuring. In some soilscertain of these
leguminous plants do not develop
nodules at their roots. This means that
these plants are abstracting nitrogen
from the soil instead of adding to it.
The development of nodules depends
upon the nature and variety of the soil;
and, as such, every leguminous plant,

before being cultivated as green manure;
must first be experimented upon.
Again, in the matter of examination of
roots for nodules, it must be remembered
that all excreseences that may be seen
at the roots of plants cannot be taken
for nitrogenous nodules ; for there had
been instances in which such excre-
scences which might appear at first sight
to be real nodules were producted by
nematodes. The subject of nematodes
and the incalculable mischief wrought
by them to plantations is still engaging
the attention of agricultural experts in
India. A bulletin on nematodes issued
by Mr. C. A. Barber some five or six
years ago, gives a large fund of informa-
tion on the subject. In his opinion the
remedy is to destroy every plant infested
with this tiresome pest. The best way
to distinguish nematodes from nitro-
genous nodules is to examine the roots
with a microscope. To the naked eye
the differences may not be visible.
There are two kinds of nitrogenous
nodules, one nearly globular in form and
the other flat and grooved, having the
appearance of minute finger-like projec-
tions from a common centre.
On the whole it might undoubtedly be
said that green manure is cheaper and
in many respects better than other
varieties of manure. Green manuring
has been found especially useful in the
case of lands reclaimed from jungle for
cultivation. It proves beneficial to such
lands in many ways. The fertilising
ingredients which would otherwise have
been washed away are utilised by these
green plants. Further, they add to the
quantity of carbon in the land. All
possible endeavours should therefore be
made to induce our ryots to go in for
the use of green manures more largely
than they do at present, especially in
view of the fact that in India the soil in
many places has already begun to feel
the strain of cultivation to which it has
been almost continuously subjected
during centuries.—Indian Agriculturist,
Vol. XXXIII., No. 7, July, 1908.

LEGUMINOUS CROPS FOR
COTTON LAND.
In the West Indies Sea Island cotton
is chiefly grown as a subsidiary crop
to suyar-cane and not as a main crop.
In the Sea Islands, however. and in
Carolina and Georgia, where Sea Island
cotton is grown atall, it usually forms
the most important and profitable crop
in the rotation. Under these conditions,
one of the chief points needing atten-
tion by the cotton farmer is the best
means of maintaining the fertility of
the land for cotton cultivation.
Artificial manures are frequently
applied, but in Farmers Bulletin 302
of the United States Department of
Agriculture—‘Sea Island cotton,’ it is
stated that one of the chief factors for
keeping the land in good condition is
the adoption of a rotation in which
leguminous crops are prominent. Cow-
peas, velvet beans, and peanuts, all of
which have been recommended for
cultivation in the West Indies, are the
chief crops of this kind grown, being
found to give excellent results on the
light soils most suitable for Sea Island
cotton, and the rotation frequently
extends over no more than two years,
cotton being planted in one season, and
a mixture of corn and cowpeas the
second year.
On the whole, it is stated, the cowpea
(Vigna catjang) is the most popular
and widely-grown leguminous crop for
growth on Sea Island cotton land. The
peculiar advantages of this crop are
that the plant is well adapted to poor
land, it is easy to cultivate, and the
produce is valuable as food for man
and stock. The Iron cowpea is specially
recommended for growth in connexion
with cotton.
The velvet bean (Mucuna pruriens,
var. utilis) is another crop which con-
stitutes a valuable source of humus, and
adds a large amount of nitrogen to
the soil on which it is grown, This
plant grows very vigorously, and _ its
vines afford excellent fodder for stock.
The plant, too, is immune to most
diseases.—The Agricultural News, Vol
VIL, No. 165. August, 1908.

world will reach common ground in
relation thereto. Animal physiology,
including human physiology, has been
making rapid strides, through the last
two or three decades, largely because
of its investigation along industrial and
economic lines. So far as the work has
been left to the medical fraternity, un-
happily, they have not been able to
develop much that is new; they, as a
rule, being not only overworked, but
underpaid in their ordinary vocation.
The investigations of animal life by our
scientific agricultural institutions have
done much to aid humanity.
All of this, however, left plent physio-
logy in the background and, as we now
stand, we hardly know how plats live,
breathe, drink, eat and die, as apparent-
ly they allmust do, and probably simi-
larly to all other living beings. In a
recent issue of the West India Agricul-
tural News there is reprinted from the
Memoirs of the Department of Agricul-
ture in India an article entitled ‘‘The
Toxic Substances Excreted by the Roots
of Plants.” We reprint thisin another
column in this issue, but desire to cast
our opinion against the accuracy of its
conclusions, even if we have to use the
Scotch verdict of ‘‘ not proven.” [Given
in the last issue, page 563. |
The general tenor of the argument
used is that some crops are found to do
very poorly after certian other crops,
when grown upon the land the follow-
ing year. The inference is that the pre-
vious crop has secreted some toxic ele-
ment inthe soil inimical to the more
recently planted crop. The first refer-
ence is made of cotton crops grown in
Egypt, in which a certain grass was
permitted to grow as a weed. It is
recognized everywhere that grasses are
inimical to the best growth of our so-
called hoed crops. Just why this is, it is
difficult to determine with the data we
have, but we are led to believe that the
grasses growing in with other crops
consume the air, moisture and plant

nutrients of the soil and, generally,
being indigenous, they are quite hardy
and difficult to extirpate and survive in
the contest that they are making with
the cultivated crops, unless positively
hoed out.
Why one crop following the other
should be bettered or injured because of
the previous crop, is not so well under-
stood. It is understood that alegumi«
nous crop enriches the soil and that any
crop following it will probably be much
benefited thereby. Sweet potatoes are
not leguminous and yet we know that
sugarcane will generally do very well
in land that has been in sweet potatoes
the previous year. We presume that
this is owing to the fact that the
sweet potatoes occupy the ground
to some depth, and in their planting,
cultivation and harvesting the soil will
receive a degree of tilth not ordinarily
given to standard crops like sugarcane
and cotton. Weare very much inclined
to think that the author of the article in
question is guessing at his conclusions,
and this particularlyas given in the
fourth statement that the substance
excreted by all crops is probably iden-
tical. All plant analyses show that the
plants consume different quantities of
the mineral constitutents of the soil.
If the plant absorbs all of its nutrition
mineral constitutents included, through
its roots and in solution with water,
then the excretion is, we belive, sent
into the air through the leaves. And
we believe that the apparently toxic
effects of previously grown crop, on
given lands have their origin in the
exhaustion of the lands by the growth
of such crops rendering them less fit for
the successful production of subsequent
crops. Everyone interested in scientific
agriculture will do well to read the

DRY-LAND FARMING IN THE
MADRAS PRESIDENCY.
By H. C. SAMPSON, B.SC.,
Deputy Director of Agriculture, Madras.
(Li llustrated.)
Dry-land farming in the Madras Presi-
dency offers great scope for investiga-
tion and improvement. In many dis-
tricts such as Bellary, Cuddapah, Ananta-
pur, Kurnool, Guntur and Nellore, the
implements in use are admirably adapted
for dry-land farming, but in the south,
the plough and the land-hoe are the
oy common implements used for dry-
ands.
Successful dry-land farming is inti-
mately connected with the conservation
of soil moisture, and the object of this
article is to show how far this can be
accomplished by judicious tillage under
the conditions prevailing in the Madras
Presidency. Before discussing the sub-
ject further it is necessary to explain
the meaning of the term “soil moisture ”
as well as its sources and how it may be
retained or lost. Soil moisture is the
water which is held in the soil after the
surplus has been allowed to drain away.
This is necessary to dissolve the plant
food which is in the soil and to convey
it to the plant roots, but the surplus of
drainage water is inimical to the healthy
‘growth of plant as it prevents the
aeration of the soil.
The sources of soil moisture are
rain, subsoil water and atmospheric
moisture.
Rain is the chief source, and it is of the
greatest importance that the land should
be prepared to receive it. A hard-baked
surface cannot absorb much water;
therefore, the surface should be loosened
by tillage so that the rain can penetrate
the soil. Subsoil water is another im-
portant source. Not only does the sub-
soil relieve the soil of its surplus water,
but it can replenish the soil moisture
when helped by proper cultivation.
Besides these two main sources, the
soil can by its hygroscopic properties,
not only absorb moisture from the air,
but can retain this in considerable
quantities if a good tilth is secured.
Thus, in parts of Madras the heavy dews
which are experienced are of great
value.
The retention of soil moisture can be
assisted by surface cultivation which
gives a loose surface soil or dry mulch.
Deep cultivation and a firm soil will
assist in keeping the soil particles to-
gether, and thus cause a more even distvri-
bution of moisture through the soil.
The following deseription will show
how these principles are carried out in
the dry-land cultivation of Madras. For
this purpose the Presidency can be
roughly divided into two tracts. In the
former draught implements other than
the plough are used, and in the latter the
plough is, as a rule, the only draught
tillage implement.
The former includes the black cotton
soils of Bellary, Cauddapah, Anantapur,
Kurnool, Guntur, and part of Nellore, as
well as the lighter soils of these and of
the Kistna district.
In the black cotton soil of this tract
two types of plough are used. One, a
heavy wooden plough which has now
been largely superseded by a heavy iron
one, and the other a much lighter |
wooden plough. The heavy plough is
only used once every five or six years,
and is followed by a very heavy bullock
hoe, known as a “‘ Bara-Guntaka ” which
works to the same depth as the plough-
ing. What benefit is derived from this
latter operation is difficult to see. The
plough works the soil to a depth of a
foot or more. Ploughing is done during
the hot weather and huge dry clods of
earth are poised up and beneficially ex-
posed totheair. In other years either the
light country plough or the bullock hoe
called a Guntaka is used for preparatory
cultivation. (Plate X VI.—vide p. 67.)
In the lighter soils of this tract this
deep ploughing is not practised.
Preparation for Sowing.—This work is
usually done with the bullock hoe or
Guntaka. If worked after the land has
been ploughed, it isa very useful imple-
ment. It makes a fine firm seed-bed and
brings any larger clods of earth to the
surface which are broken down by
subsequent rains. The practice of work-
ing the soil with the Guntaka without
previous ploughing is sometimes prac-
tised. This is objectionable as only the
surface is loosened and the soil below
remains hard set and lacks aération.
Occasionally, when the rains are very
late, some such method of cultivation
has to be resorted to, but the ‘‘ Gorru”
or seed drill without the bamboo sowing
attachment is preferable to the Guntaka.
(Plate X VII.—vide p. 67). Insome places
this is weighted with stones and worked
across the land in both directions, and

tages over broadcast sowing. It regu-
lates the space for each plant. Sowing
can be done when the land is com-
paratively dry, asthe drill can be set to
sow at the depth where there is most
moisture. Good germination is assured
gad there is a considerable saving of
seed.
A fter cultivation.— Several implements
are in use in different parts for this
work, but the best are the Dunthalu
which is used in the Bellary District, and
a small Guntaka, which is a similar
implement with a wider blade, and in
the case of cotton and red gram is often
ussd after the cereal catch crop has been
reaped. The others work deep and
throw the soil up round the plants form-
ing ridges and furrows. . The Dunthalu
consists of aset of three to six small
bullock hoes which are jattached to
a wide yoke pole and is drawn by
two bullocks (page 67). Each hoe or
danthi has an iron blade some 9 inches
wide, which the driver guides between
two rows of the crop. The hoeing is
done after a good rain has fallen, but as
a rule the farmer does not seem to realise
that the operation is just as necessary
when the surface has caked after a light
rain, and,in consequeuce, this implement
is seldom worked more than two or
three times.*
Throughout the Tamil country and in
Malabar the plough is, with few excep-
tions, the only tillage implement for dry
cultivation. In Malabar the conserva-
tion of soil moisture is not so essential
owing to the heavy and continuous rain-
fall during the growing season. Plough-
ing commences with the close of the
monsoon, and is continued afterwards
until the early sowing rains commence
in April and May. Inthe dry Eastern
Tamil country the rainfall is limited,
and does not admit of repeated plough-
ings before the sowing rains. The land
is usually left untilled until a ploughing
rain falls, when as large an area as
possibleis ploughed. Aboutfour plough-
ings are usually given. The ryot then
waits for a sowing rain when the seed is
sown broadcast and lightly ploughed in.
The subordinate pulse crop, usually
Cajanus indicus or Dolichos lablab, is
sown immediately afterwards, the seed
being dropped behind a light plough.
Ina few districts the value of a firm
seed-bed is appreciated, and after sowing,
the soil is made firm by dragging a
roughly made brush harrow across the

ploughing. In parts of Tinnevelly also
the ryots cultivating red soil have an
implement made like a large wooden
rake which is used to break the surface
crust and assist the growth of the young
crop. hen the crop is established,
the plough is worked through it. This
rough and ready method of cultivation
gives a good crop in good seasons, but if
the rain fails, the result is often a partial
or complete failure.
In parts of South Arcot this practice
of ploughing through the crop has been
entirely given upin favour of the more
efficient practice of hand hoeing. Here
the dry cereal is considered as a catch
crop for the groundnut crop, the seed of
which is dibbled in after the cereal is
well established. The land is often hoed
two or three times. The first hoeing
includes weeding and thinning, while
the others are mainly for loosening the
soil surface, and is done even if the land
is perfectly free from weeds. The in-
troduction of the harrow into the Tamil
country would bean immense advantage.
If used instead of the plough, the surface
soil alone svould be loosened and thus
the soil moisture would be better con-
served. The ground would be left level
instead of in ridges and furrows, which
are always objectionable in the case ot a
dry crop asthe ground soon dries out
and subsequently rain runs down the
furrows before it can soak in. If the
harrow were used instead of the hand
hoe, the cost of the work would be
greatly reduced and the farmer would
be able to complete the work in less
than a quarter of the time. The time
that this operation takes is of great im-
portance on the lighter soils. A harrow
made in the shape of an equilateral
triangle has been found to answer this
purpose well, and is not too expensive or
too elaborate for the ordinary culti-
vator. This and other implements used
in dry cultivation are illustrated.—Agri-

RURAL AGRICULTURE IN CEYLON:
AND HOW IT MIGHT BE IMPROVED,
THE DISCUSSION.
The reading of the paper on the above sub-
ject (given on page 569 of the Dec. issue) by
Mr, W. A. de Silva, before the meeting of the
Board of Agriculture on the 3rd December.
was followed by the following speeches —
Dr. WILLIS AND THE NEED
FOR AGRICULTURAL ‘* PRELIMINARIES ”’
Dr. Wiis :—I think, Sir, it is a very
satisfactory sign of the times that the Soc-
iety is beginning to realise clearly that before
you can make progress in Agriculture you
have to make progress in the preliminaries
of agriculture. In Ceylon we have hardly
yet got through the preliminaries, and yet
we have been trying too much to attend to
the agricultural part. With regard to Kuro-
pean planters they have passed, so to speak,
through the preliminaries ; but the native
cultivators have not, and it is consequently
almost idle to introduce new things amongst
the villagers, because they have not got the
necessary preliminary conditions to go on
with. The two principal things on which
the whole industry rests are
FINANCE AND TRANSPORT,
and unless we have sound conditions as
regards these it is hopeless to go ahead to
any serious extent and get the people to take
any great interest in growing things which
must be sold in outside markets. Consequent-
ly it is a very good thing to see that these
papers tend to increase generally the interest
taken in the question of the small co-opera-
tive systems for the supply of money. I use
the word in a broad sense. It may be in the
supplying of paddy seed, in manures, in sell.
Miscellaneous
ing produce in Colombo. It may be anythin&
you like, but the central principle is co-opera-
tion amongst the poorer classes, to enable
them to carry out what would otherwise
require the capitalist to put through. In
this country I have been trying to induce
town Societies, who have, presumably, a
little money, to help their village brethren—
for whose benefit, after all, we were estab-
lished, —by starting co-operation for the sale
of produce and the supply of manures, and
soon. The ordinary villager has no money
at all, and consequently he cannot hope to
do anything beyond live from hand _ to
mouth, I think, therefore, it is very satis-
factory indeed to see the tendeney which is
coming over the whole country to attend
to these preliminaries. Transport, thanks to
Government, is very well developed on the
whole in Ceylon and there are sufficient,
villagers along the branch roads and railways
to carry out any agricultural improvement
that is necessary. ‘The essential weak point
of the whole Ceylon system of agriculture is
money. To raise the people to a higher
plane you must first of all attend to the
preliminaries of agriculture, and find them
money, This must be forthcoming before
you go ahead in agricultural matters strictly
so called. *(Hear, hear.)
GOVERNMENT'S ATTITUDE,
H. EK. the GOVERNOR :—Equally with Dr.
Willis I welcome the appearance of two
papers such as those under discussion.
Members may recollect that when I assumed
the administration of the Colony I hesitated,
as naturally I would do for some little time,
to give an expression of opinion regarding
the agricultural requirements of the Colony.
However, you gentlemen have seen, and the
community generally have seen, rather
lengthy references to loans to native agricul-
turists in the despatches which I sent to
the Secretary of State. The Secretary of
State has approved of the proposal that
funds shall be voted to assist agriculturists,
but he requires regulations on the subject
to be submitted to him. It is particularly
valuable tome as the Governor of the Colony
to have papers before me such as those which
have been read or taken as read, and 1
may say I shall welcome any expression of
opinion and recommendation from those who
are qualified to write upon the subject and
advise how best agriculturists can be assisted
in such a manner that we do not pauperise
* It may make matters clearer if we add the
following note. The preliminaries to agriculture are
land, climate, labour, transport, capital, drainage
irrigation, tillage, education, and suitable crops.
The most important are land, capital, education
and transport, so far as Ceylon now is concerned
and until the villager has land ayailable, transport
facilities, and capital to work any improved
method or new crop, he cannot progress beyond
his present state. We called attention to this at
the very first meeting of the Board,—Z£d,
Miscellaneous.
them more than these poor fellows already
are. We want toincrease their self-respect
and at the same time deliver them from the
clutches of the money-lender. It was at a
very early meeting of this Society that I
referred to the system of usury going on
in this colony. It was my endeavour to
grapple this ogre of usury, but when it
came to prospective legislation I found the
whole matter was rife with difficulty. It was
in consequence of this that I came to the
opinion that it was the Government them-
selves who must come to the assistance of
the people—train the people, educate the
people, help the people. As Mr. de Silva
has said, this must be done on strict business
principles, It must be done by co-operation
with the people, working with the people,
and the people themselves must do a great
deal to come to the state of perfection to
which Mr. de Silva points out now exists
in Denmark. We have of course a very up-
hill game to fight. Our Ceylonese cultivators,
unfortunately, are extremely apathetic
and have to be shown the value of labour.
I quite fall in with Mr. de Silva when he
says their efforts through the year should
not be devoted simply to the paddy patches,
but that they should go in for other means
of making a livelihood. It may yet be
found that by improving the state of agricul-
ture generally that the solution of the
food question is not to be found altogether
in the extension and development of rice
fields, but that other food products may
be raised such as Indian maize, which is
not received with that disfavour which it
once was. As I say, the members of the
Society and the Government,—everybody
concerned who takes an interest in agricul-
ture—have a weary, stiff problem before
them in order to bring this lesson home
to the people. For instance, Mr. de Silva
points out quite rightly the wretched yield
of rice per acre. What is that due to? It
is duein a great measure because the people
will not transplant the paddy, except in
a few districts such as Kegalla and on the
South Coast, but will still insist on scatter-
ing the paddy broadcast and rearing it in
a way which gives small returns on a
wasteful expenditure of seed paddy. H. E.
then repeated that he would be only too
glad if communications such as he had re-
ferred to were sent to his Private Secretary.
THE QUESTION OF BURMA RICE.
Mr. F. C. RoLEs :—Your Excellency, may
I be allowed to make a few remarks on
Mr. de Silva’s paper? My attention has
just been directed to a reference in the
paper to the subject of Burma rice. That
is a subject of much and of growing
importance. I have hada few words with
Mr. de Silva and pointed out to him that
there is no prejudice amongst the labourers
against Burma rice. Itis the raw product
only that they object to because of their
[JANUARY, 1909.
method of boiling once in 24 hours. Steamed
rice has been imported from Rangoon, which
has been highly reported on by a number of
estate superintendents, kanganies and coolies,
The remarks regarding white Burma rice,
farther on in the same paragraph, has re-
ference torice which has been imported,
here for many years. It is used for con-
fectionery and hoppers and not on estates,
and it is white Burma rice because the inner
skin has been removed; that skin is left on
in cargo, or Loonzain rice, which is the kind
of rice required for consumption on estates.
By a second hulling the number of paddy
grains can be reduced to a minimum of 2 per
cent. If that paddy is steamed first and
hulled afterwards it is entirely acceptable to
the consumer. Now it is simply a question
of price and further efforts are being made,
as a sequel to the discussion of the subject in
Ceylon and in Rangoon and neighbourhood,
in steaming on a small scale. At the present
time there are small shipments in the off
season; and considerably increased quantities
are expected in the coming season. (Hear,
hear.)
AN EGYPTIAN AGRICULTURALIST’S VIEWS,
Mr. J. S. J. McCall:—Your Excellency,
gentlemen: Althouh a visitor, 1 would like
to saya few words in answer to this question
of loans to agriculturists, as we had the
very same problem in Egypt, where I
was Agricultural Lecturer for three years.
We could not get money to improve matters.
But, by the Government taking an interest
in the subject, we managed to get the leading
agriculturalists in the country—those who
had the money—to form among themselves
an Agricultural Society, and a large num-
ber to. put money intothis Society. The
Society purchased manures from the
manure firms, guaranteed their purity, distri-
buted them to the different villages, and sent
men who were qualified to deal with the
question of manuring to superintend the
application of the manures to the village fields.
At first the manures lay by the hundredweight
in the villages, and the villagers said : ‘‘ We
will not touch them, We have been culti-
vating rice, wheat, barley and the different
crops of the country for centuries, and we
are not going to alter our methods”—in the
true Mohammedan style. The Society
replied: ‘* We will present to you these
manures. You may apply them to half
your fields, the other half do with as hitherto
in your methods and compare results. If
your crops suffer from the application of the
manures, we, as a Society, will guarantee
to compensate you, but if the crop benefits
over the price of the manure we will ex-
pect you to pay us the price of the manure.”
That was the state four years ago, and the
result was that last year the Khediveal Agri-
cultural Society imported £175,000 sterling
of artificial manures. and could not supply
the natives quick enough. We absolutely
+ ‘i Bi fl

could not get the manure into the country
quick enough; and the effect of manuring
on the general agriculture of the country
was that, four years ago, the price of straw,
etc., in Egypt was nearly double the price
that it is at the present day, as the increase
of crop owing to the beneficial action of
the manure put a larger quantity of pro-
duce on the market. Some people might
think that this. would result in no benefit to
the cultivator ; but that would be a mistaken
idea, as artificial, manures applied carefully,
in the correct proportions and the correct
manures to the correct crops, seldom give
less than 100 per cent, on the cost of the
manures. The natives of Ceylon know
nothing about manures, but that is not to
their discredit. Only 10 years ago in Great
Britain there were very few farmers who
knew anything about artificial manures,
Some people have the idea that manures
are very flexible quantities: this is also a
fallacy, as a manure has only a definite value
and can only give a definite increase, and this
increase to alarge extent is dependent on the
right manure being put to the right crop,
Dr. Witiis—referring to what Mr, Mc-
Call had said—remarked that he had been
round the districts where at present artificial
manure is unknown. Some said they knew
nothing about itand some said once manur-
ing was started they must goon with it.
That was of course true. It was an essential
condition to progress in anything. He
said it had been pointed out, and the
suggestion he thought was a sound one, that
it would payin the long run if the Par-
ent Society in Colombo were prepared
to supply local societies with small quantities
of selected manure for trial in the districts.
That might be tried on the lines Mr, McCall
spoke of.
NOTES AND QUERIES.
G. E.—The Centre of Agricultural
Education in the Madras Presidency is
Coimbatore, where'there is a College and
a farm of 450acres, Apply to the
Principal for syllabus. The course is a
three years’ one. ;
W. DE S.—The cultivated anatto bears
a pink flower, but there is also a white
variety. It is the former that is
commonly cultivated, but the white
flowered variety is found semi-wild in
India, the natives believing thatit is
indigenous. The principal use of the
dye is for colouring butter and cheese.
It isusually dissolved out with olive oil.

DanicHA.—This is an Indian name for
Sesbanea aculeata, which is well thought
of asa green manure and is also a fibre

may not grow this delicious fruit in
your own garden.
M. G.—The Coorg is a much smaller
orange than the Nagpur. The latter is
more after the styleof our best King

““CHow McLuiER.”’—This is being tried
at the Government Stock Garden. The
plant belongs to the cabbage family,
Its value is as a cattle food.
GARDENER.—Have you tried bone
meal? I would recommend your giving
up heavy applications of cattle manure
for a time, as the orange trees have
most probably had enough of. nitro-
genous food and want more of. phos-
phate for fruit formation.

“THE QUEEN OF FLOWERS.”
A sudden gush of light and odours bland,
And lo—the Rose ! the Rose !
The rose has very justly been desig-
nated the Queen of Fiowers. So full of
beauty and charm is the rose, and so
numerous are the _ points of interest
connected with it, that chapters could
be written about it. In all ages and
by universal consent, throughout the
civilised world, undisputed precedence
among fiowers has been conceded the

rose, “ Queen of them all.” The favour-

place in general literature that no othe
pine can rival. In the sacred writings,

countries, this ‘‘Queen of Flowers” i
the epitome of beauty and fragrance,
the emblem of refined sensual enjoyment,
‘richer and sweeter far than aught
betore.” The rose is woven in the
ancient Greek Anthologies. In the
Planudean Anthology occur some beauti-
ful couplets ascribed to more than One
writer in which the wish is breathed :
Oh that I were yon blushing rose,
Which even now thy hands have pressed,
That 1 might love in sweet repose,
Reclining on thy snowy breast !
Plato presents a lovely picture of the
God of Love laid asleep among roses,
with the bees settling upon his lips ; and
there is a favourite passagefrom Julian -
Twining a wreath, [ found one day,
Love that among the roses lay.
Therose was dedicated to Awrora as
the emblem of youth; to Venus of
beauty ; and toCupid of fugacity and
danger. The latter is said to have given
it asa bribe to Harpociates the God of
Silence, hence the saying ‘‘under the
rose.” Modern feelings have run into
the same sort of amorous fancy as that
of the earlier writers, for have we not
Romeo in Shakespeare expressing the
wish ‘‘Oh that I were a glove upon that

_ And we have writers all along descant-
ing on the admirable qualities of the
rose. It has been the subject of scientific
monographs and of floricultural disquisi-
tions, and many are the writings extant
about it. The species which has been

Roses have been grown for so many
centuries and have been crossed and
recrossed so often that itis difficult to
refer the cultivated forms to their wild
prototypes. The older roses are thought

R. Centifolia, a native of the Caucasus,
contributing its share. Under natural
circumstances rose flowers do not secrete
honey, the attraction for insects being
provided, according to Muller, by the
colour and perfume and the abundance
of pollen for food.
The cuitivation of the rose affords
employment to thousands of human
beings— cultivation for the table and
for the manufacture of attarand rose
water. R. damascene is cultivated in
somo parts of Roumelia and in India,
chiefly near Ghazipur, for the purpose
of making attar and rosewater. Drury
mentions that it takes 200,000 roses to
yield the weight of a rupee in attar and
this quantity sells on the spot for R100.
In Europe rose water is chiefly produced
from R. Centifolia, grown for the pur-
pose at Micham, and much more abun-
dantly in the South of France. Conserve
of roses and infusion of roses, two
medicinal preparations retained for
their agreeable qualities rather than for
any special virtue, are prepared from
the petals of KH. gallica, says an old
writer. Conserve of dog roses is made

IN THE MANUFACTURE OF PILLS.
The cosmopolitian character of the rose
is wellknown and it flourishes equally
well in sub-Alpine as in equatorial re-
gions; and the patient skill of cultiva-
tors has been successful in depriving it
of one of its attributes—it has ceased to
be an emblem of Summer, ‘‘ pride of the
Summer, garden queen.” By making
careful selections of species and rearing
hybrids, varieties deservedly called Per-
petual have been obtained, and, so far
as cold countries are concerned, roses
can be got now at any season.
Of all plants grown in Ceylon for the
sake of their flowers, as in other coun-
tries, none have gained so much admira-
tion as the rose. It has been rightly
said that a garden without roses is a
misnomer. But how many there are in
this country who, possessing the
material, do not set about in the right
way of doing things. By tar the most
effective way of growing roses is to have
them distributed through every part of
. the garden.
The rose is propagated by seeds, cut-
tings, layers and suckers (in the case of
plants on their own roots), and by bud-
ding and grafting. Seed-sowing is only
had recourse to with a view of obtaining
improved varieties. Layering is per-
formed by simply bending the shoot or
shoots, desired to root down to the
ground, cutting the same half way
[JANUARY, 1909.
through longitudinally and pegging it
down at that point, so that the wounded
surface shall come in contact with the
sandy soil, watering in dry weather
to keep the soil moist. After it has
rooted effect separation witha clean cut.
Budding and grafting are the modus
operandi generally followed at the per-
petuation of the rose and many choice
trees and shrubs as well. These methods,
however, had better be left to expert
growers, and we will proceed to the
UNIVERSAL SYSTEM OF PROPAGATION.
There is no difficulty in raising one’s
own roses from cuttings. The cutting
should be prepared by clipping off side
shoots, but do not remove the leaves;
six or eight inches is long enough for a
cutting ; see that it is cut off straight at
the base just below aknot or bud, or
left as it has been slipped off the branch
taken off with a heel, that is with a little
of the old ripened wood attached.
The rose grows vigorously in most kinds
of soil. Good ordinary garden soil will
produce the rose large enough, but to
grow it into perfection abed should be
previously prepared. The rose does best
in a light free soil, a little fresh, amended
from time to time with some well-
decomposed manure. A calcareous soil
is especially recommended. Delicate
varieties do best in fertile, sandy soils,
and in peat earth. The dog rose grows
vigorously in stiff earth. For nearly
all roses, however, the soil can scarcely
be too rich. The plants delight in a
stiff loam liberally incorporated with
manure, and no excellencies of variety,
climate, or culture can compensate
for the absence of this indispensable
resideratum. Where the natural soil is
light and sandy, the whole bed should
be removed toa depth of two feet, and
replaced with the richest natural fibrous
loam at hand, or leaf mould, thoroughly
mixed with decomposed dung. The
MOST SUITABLE SOIL FOR GROWING
ROSES
in the ground is that which is called a
clay loam, that is, which is neither
black soil nor sandy soil. A clay loam
is more retentive and does not dryso
soon as sandy soil. A sunny position
with free wind is desirable; shade
and closeness induce a number of
fungoid and insect diseases. Thorough
preparation of the soil with manure is
desirable however suitable the soil itself
may be. The bed should be clear of the
roots of surrounding trees which would
impoverish the soil and rob the plants
of the nutriment intended for them.
This could be guarded against by cutting
a deep drain round the beds. After the
bed has been prepared open a shallow
.

trench, about six inches deep across it
and place the cuttings inclined against
the steeper side four to five inches apart
about which sprinkle some sand, river
sand for preference; fill in with the soil
and press firmly around the cuttings.
Open the next line about seven inches
distant and proceed in the same manner,
finally passing the watering-can lightly
over the bed. Most rose growers prefer
pot culture, evidently with the object of
being able to move the plants from place
to place. But the bloom of pot plants
is not always so satisfactory as those
from plants grown in the ground. The
soil for pot plants should be made up of
river soil or alluvial loam, failing this,
loamy cabook material, and half manure.
If the manure is not old, earthworms
and white ants are generated; and old
mannre will sometimes contain the
larvee of the Chafer Beetle—destructive
to rose trees by eating the root. The
best planis to spread out the manure
and let the birds aud chickens pick up the
grubs and sift it before using. Soil, too,
sometimes contains the eggs of earth-
worms and in that case it should be
incinerated. Burning the soil would
effect great improvemeut in the case of
clay soil, rendering it light and less
retentive of moisture. The addition of
leaf mould would greatly improve the
quality of the potting soil. Itis obviously
necessary
AFTER PLANTING CUTTINGS
that they should be kept shaded and
the ground kept moist until they make
steady young growth. Cadjans or
bamboo tats would do very well for
shading; and once the slips have estab-
lished a footing the sunshades should
be removed. The rose plants, like most
other, should be judiciously watered
and notswamped. In Nature vegetation
makes little progress during incessant
rains ; but as soon as the rain ceases and
the sun shines, the grass and weeds, and
cultivated crops spring up. In _ like
manner, if the soil round the rose plants
is kept continually damp and the sun
and air not allowed to circulate through
it, the plants are sure to be unhealthy.—

THE ROTATION OF CROPS.
This is one of the oldest phases of
good kitchen gardening, yet it is safe
to say that none is less pertectly under-
stood by the majority of cultivators.
The reasons for this failure on behalf of
cultivators to grasp the elements of the
rotation of crops need not be sought for
in vain, the chief one being that hard-
and-fast rules cannot be laid down
75 Miscellaneous.
concerning what particular crop shall
succeed an existing one, and also that in
many cases the grower has only a pactial
control over circumstances, and con-
sequently is obliged to do the best he can
with the soil at his command.
At the outset it may be as well to
briefly consider the principles which
underlie the retation of crops. The
chief object with most cultivators in
changing crops is to get the best possible
results from the soil, the idea being
that different classes of plants require
different kinds of food for their upbuild-
ing; and there is, no doubt, a lot of
wisdom insuch acourse, Another point,
however, which is frequently overlooked,
but which is equally or even more
important, is the fact that certain
diseases and pests attack certain plants
only. and therefore by keeping these
plants off the ground for two or three
years a disease may beeradicated. Club-
root of the Cabbage family is a disease
which may be mentioned as an example.
As previously stated, a cultivator
frequently has to do the best he can
under existing circumstances, and often
these are such as to render it imperative
to overlap crops which would be much
better if given entirely fresh ground.
There are, however, many gardens
wherein it is possible to give the various
plots a change of crop each season, and
wherever such a course is possible every
effort should be made to adopt it.
As the question is naturally a very
complicated one, only general indications
and hints as to carrying out the work
can be given; but these, coupled with
intelligent application, will, I hope,
prove of some use to amateurs and
others who have only given the matter
a passing thought. Taking the Cabbage
family first, it has been proved that all
the members thereof require practically
the same kinds of food, and in addition,
as previously stated, all are subject to
attacks of club-root and other diseases
and pests which do not attack some
other classes of plants; hence it would
be unwise to let a crop of Cauliflowers,
for example, to be followed by spring
gabbages, as the former will. to a great
extent, have exhausted the soil of those
particular foods needed by the Cabbages,
and any disease which might have been
present on the first crop would almost
certainly make a host of the second. In
practice it is found to bea good plan to
let deep rooting crops, such as Parsnips,
Carrots or Beetroots, follow any of the
Cabbage family.
Potatoes, again, are another crop which
ought not to occupy thesame ground
two years running, as they are veritable
gluttons so far ag potassic manures are
Miscellaneous.
concerned, andin practice it has been
proved that much better results can be
obtained by only cropping a certain plot
with potatoes once in three years. Any
of the Cabbage family, Peas, Beans or
Onions may, with advantage and
satety, follow Potatoes, Carrots, Parsnips
Beetroots or Celery. Generally speak-
ing, Beans should not follow Peas nor
vice versa, and this applies to any kinds
which are closely related or belong to
the same family, hence Tomatoes should
not follow Potatoes. The same general
remarks apply to flowers, and any Sweet
Pea enthusiast, for instance, will avoid
growing his favourites on the same soil
two years running if he possibly can.
In gardens where rotation is impossible
of course the food difficulty is overcome
to a great extent by judicious manuring,
but the question of disease or insect
attack can be only thoroughly dealt
with by keeping a_ particular plot free
from a crop that is likely to be attacked,
for several years.—Garden, Vol. LXXIL.,

SIXTEENTH ANNUAL AGRICUL-
TURAL CAMP MEETING FAIR AT
CALHOUN, LOUISIANA.
ln organizing the several experiment
stations of the State of Louisiana some
twenty years ago, Governor McEnery
and Dr. W. C. Stubbs selected a site in
the hills of Ouachita parish in North
Louisiana for an experiment station,
which should be adapted to the needs of
the hill-farmers in contradistinction to
those of the alluvial lands and the
prairie lands and the pine flat lands.
Right from the start the station at
Calhoun became one of the most popular
in the State and excellent results were at
once perceptible. The entire farming
community within reasonable reach was
affected by the station’s influence along
educational lines in improved farming,
and that good work has been going on
ever since. An Agricultural Society was
organized, which held monthly meetings,
and this brought in hundreds and some-
times thousands of visitors to the
station. This led in turn to agricultural
camp meetings, and finally toa Camp
Meeting Fair, the various visitors bring-
ing in from their farms specimens of
their home products; and now the annual
fair on the experiment station grounds
at Calhoun has become a permanent
feature, and the display of Louisiana
products there would satisfy the most
sceptical as to the capacity of our State
to produce almost any known agri-
cultural product, and to produce it, if
you please, in the hills of North Louisiana,

where the lands are not considered as
fertile asthe alluvial lands. Ina test
made some years ago of the amount of
corn grown comparatively, Governor
M. J. Foster was one of the Examiners,
and by actual test, measurement of the
land and weight of the corn gathered, it
was found that the production of corn
equalled over a hundred bushels per
acre. Of course no such crop is grown
generally in the hills of North Louisiana,
nor anywhere else in the United States,
but it shows what can be done there
with intense culture.—Zowisiana Planter

AN AGRICULTURAL COLLEGE
FOR BENGAL.
The new Agricultural College at Sa-
baur, of which Sir Andrew Fraser laid
the foundation-stone recently, is an
undertaking which ought torouse the
utmost enthusiasm throughout Bengal.
Itis almost the first step towards the
establishment of genuine technical edu-
cation in this Province. that is, education
which applies the results of scientific
research to a great staple industry, and
which enables those engaged in that
industry to do their work scientifically.
When the College is completed, Agricul-
ture, which is the chief industry of
Bengal, will begin to receive upon an
adequate scale the benefits of modern
science. Hitherto, though agricultural
training has not been wholly neglected,
the effcrts made in that direction have
been tentative and have been rewarded
with indifferent success. As Mr. Gour-
lay mentioned in his admirable sketzh
of the course of events which has led to
the establishment of a College, officers of
the Provincial Service were sent to Ciren-
cester to be trained, and later instruc-
tion in agricultural subjects was givenat
Sibpur. But the results were not satis-
factory and the Province gained little
except, perhaps, the services of the
late Mr. N. G. Mukerji. Agriculture in
Bengal may. therefore, be said to be
now atthe opening of a new era. No
pains have been spared to secure a site
for the new College where it will be
easily accessible, and where land will be
available on which as many as _ possible
of the principal crops of the Province
can be experimentally cultivated, These
conditions are fulfilled at Sabaur. As for
the College itself, it isclear from Mr,
Gourlay’s lucid description that every
need of the agricultural student has
been carefully anticipated. If thechoice
of the staff is equally felicitous, Bengal
ee eee eee

will have an ideal institution, and we
hope that Mr. Gourlay may be as fortu-
nate in this respect as in others. He
will, of course, realise that while high
scientific attainments are desirable quali-
fications, as is equally necessary that
“the professors should be capable
teachers, endowed with sympathy and
with the gift of winning the confidence
of their students. —Ep. C.0.]
TAPPING YOUNG RUBBER: AND
MANURING OF COCONUTS.
Dec. 9th.
DeaR Sir,—I was interested to read Dr.
Willis’s letter giving his views on what is young
rubber. 1 would not putthe limit for tapping
age as high as the Director does; 7 years, of fair
average growth, is old enough for trees to have
excellent rubber,
and Magazine of the Ceylon Agricultural Society. 83
But, my point Dr. Willis fails to take up,
viz., that his approval of tapping young trees
is being used to uphold the tapping of sapling
rubbers, 3 years old, which is detrimental to the
interests of our industry. Messrs. Lee Hedges
& Co. are quite in their rights to make use
of Dr, Willis’s approval of their system, but he
should not allow it to be used unless strictly
as he meant it. While writing, I may also allude
to another point. The Director, as Editor of
The Tropical Agriculturist, has stated that there
is practically nothing new to write about coco-
nut cultivation! May I give him a suggestion?
Tell us about coconut manuring; the literature
on that pointis not exhaustive, I was only
recently discussing the matter witha friend,
and our discussion on the right methods of
manuring coconuts would have made an_inter-
esting article. But your space is limited.—
Yours truly,

LATEST ON COCONUT PLANTING.
The veteran Mr. W. H. Wright of Mirigama
now &8 years of age, whose coconut property
is a model of its kind and who usually picks
an average of 110,000 to 115,000 nuts per month,
told us some days ago he is only picking 50,000
per month at present ; and that crops are short
all over the island. At Veyangoda the dessica-
ting mills have had a temporary cessation of
work for want of ‘nuts, sellers preferring to
sell the copra at present prices. Mr. Wright
picks twelve crops a year: six small ones
from November to April, and six larger from
May to October.__He has just now some fine
shows of blossom on his Brazil Nut and
English (eating) Chestnut trees, promising
fruit before long.
Matara, Telijjawila, Dec. 17th.
Dear Sir,—The information about coconuts
from Mirigama is interesting. Short crops seem
to be universal, but I think there was an im-
provement this year compared to the crops in
1906. Twelve crops a year are not known in
this district—six being the usual number, of
which those in May and July are the biggest.
They are about three times the number plucked
in the first and last cropsof the year. There are
signs of good crops in 1909, due, of course, to
the very favourable weather we have been
having.— Yours faithfully,
JAS. A. WICKREMERATNE.

Marawila, Dec. 16th.
Dear §1R,—The November number of the
Tropical Agriculturist reminds me of the old .
issues before it degenerated into a rubber jour-
nal, There are in it many valuable articles
which I commend to the cluse study of coco-
nut planters. I refer to the very valuable and
practical articles on pages 457-469.
The statement, ‘‘It is a well-known fact that
a soil on which plants are growing, loses much
more water by evaporation than does a bare
soil,” reminded me very forcibly of wy valued
friend the late William Jardine, who consis-
tently asserted that coconut estates will be all
the better for being free of grass and herbage,
Of course, this is not practicable, as cattle are
an esseptial of coconut estates. But this can
with advantage be carried out on new clearings, .
where absence of a good pasturage will not
attract cattle as greatlyas now. What has Mr.
Carruthers to say to this?
Some of the coconut estates that suffered
greatly from the drought had a thick carpet of
rank hrold growing on them. If this had
been clean weeded, the soil would have bene-
fited greatly by the stirring it would have
received, however slight it might have been, and
the trees, from the mulch of grass which could
have been placed in a circle round them.
The Government should have printed in the
vernaculars the article on ‘‘ Leaf manuring in
South Canara” and circulated broadcast all
the island over. Perhaps it is not so necessary
in the Tamil-speaking Northern and Eastern
Provinces as in the other provinces. As far as
my observation has gone, in those provinces the
careful and intelligent cultivation one notices
amongst the ryots in Southern India, is prac-
tised by their Tamil brethren with whom they
are closely allied. No vegetable matter, no
garden sweepings, no cadjans from the roofs
and fences is allowed to go to waste or is burnt.
Everything goes to the manure heap, and
eventually to the fields. The Sinhalese goiya
never cdloes that. He has always dirt in the
wrong place. Agricultural Instructors can be use-
fully employed travelling about the country and
giving plain, practical lectures on paddy culti-
vation. Mr Milne, in the article on ‘* Conser-
vation of soil moisture,” has a good word to say
for the native plough. It must be understood
that the Indian plough is a far more effec-
tive implement than the Sinhalese plough.
Both are _ practically ‘‘cultivators,” but the
former, being broader, does more econo-
mical work. ae S

CEARA RUBBER IN CHRISTMAS
ISLAND.
Mr Tait writes :—‘t The few plants we have
here are makiug good growth, having reached a
height of 12 feet and a girth of 7 inches, at 3
feet from the ground, at nine months old ; from
all accounts this seems a fair growth.”
This certainly seems satisfactory considering
the peculiar nature of the Christmas Island
soil. The whole island consists of three raised
coral-reefs rising from sea level to about 1,100
feet altitude. Over this coral rock lies a layer of
phosphate of alumina which is of some depth
near the settlement. During the dry season, the
country gets very dry and owing to the nature
of the rock the water sinks through till it ar-
rives at the volcanic rock which forms the base
of the island at sea level. In such a peculiar
soil and climate it is almost surprising that
anything grows well, but the whole island is
forested with large trees; and vegetables, limes,
papaya, and other fruit trees grow well on the
rich brown soil near the settlement. Para
rubber has been planted as well as ceara, but
it is probable that the latter will prove the most
suitable.

‘Mrxico as A TRA-Growrne Country.—With
the object of securing reliable information as to
the possibilities of agricultural development in
Mexico, the Government of that country com-
missioned a foreign expert to investigate agri-
cultural conditions in various tropical and sub-
tropical countries. According to the latest re
port of the British Consul-General at Mexico

advises the Government to establish a Mexican
Department of Agriculture. He urges that
Mexico has special advantages for the growing
of tea, cacao, rice and fruit of many kinds.
Tue Disposat or Tea Prunines.—In referring
recently to the views of Messrs. Joseph Fraser
and Bamber, Dr. Willis and Mr. Petch on the
disposal of tea prunings—whether by burying
or burning—we alluded to the last-named
as being inclined (at any rate 18 months ago)
to support burying, except where a field is
subject to root disease. We are, however,
reminded by one who has followed the Govern-
ment Mycologist’s work closely that we would
be wide of the mark if we assumed that Mr.
Petch believes in burying prunings under any
circumstances. We certainly did not assume
this, for his paper of May 1907 was very strong
against burying where root disease existed ;
he also pointed out the difficulties often ex-
perienced in securing rapid decay of prunings
buried in holes. Mr. Petch has, we hear,
rather been devoting himself to urging the
burning of them for the last four years and
holds there is as yet no evidence whatever
in favour of burying: that, in fact, there is
scarcely a set of figures dealing with any
cultivation in the Island which will bear
five minutes’ examination: and that until
Mr. Joseph Fraser submits his figures to
criticism, they must scientifically be regarded
as non-existent! The Experiment station
Committee, we believe, have not always found
figures reliable facts to go upon; and what
passes for experiment in tropical agriculture
has before this been proved to be futile imitation.
We trust, however, that Mr. Joseph Fraser
may have something to say on the subject ere
next Pitakande meeting comes along.
INDIAN TEA ASSOCIATION.
(Meeting at Calcutta on Dec. 22.)
Mosguriro Buicur.
In connection with the pamphlet recently
published by Mr Antram on Mosquito Blight, a
letter of 17th December from Messrs Shaw
Wallace & Co. was read. They urged the im-
portance of joint action being at once taken by
Proprietors to deal with the blight in view of
the danger that, if remedial measures are de-
layed, it may increase to an alarming extent.
They emphasised the point made by Mr Antram
in regard to the necessity for thorough satura-
tion of the bush in spraying, and expressed the
opinion that the Committee should impress on
Proprietors that spraying should be pursued
with more ‘vigour and perseverance than
hitherto, and that every precaution should
be taken to ensure thoroughness, But
103
even spraying to this* extent would not, in
their viow, be sufficient, unless the blocks of
tea treated were absolutely isolated: and it
was with this in mind that they suggested that
if headway against the blight were to be made,
joint measures inthe affected districts would
be imperative. As they pointed out, it would
be hopeless to carry out protective measures,
however complete, in any one garden, if the
surrounding gardens took no steps and re-
mained a recruiting ground for fresh infection.
‘They considered that members should be cir-
cularised with a view to inducing them to com-
bine in the matter.—The points raised by
Messrs. Shaw Wallace & Co. were discussed at
length by the Committee who were in com-
plete agreement as to the desirability of ener-
getic combined action being taken on the lines
indicated. The only question was as to how far
planters would undertake the expense of spray-
ing areas not obviously suffering from the
blight.—Asa preliminary step it was suggested
that some group of gardens in ove of the attected
districts might be approached with a view to
get them to combine and take the most thorough
measures—especially in the matter of spraying
the whole area of their tea—for one or two
seasons. If this could be arranged and the
method were found to be effective, the Com-
mittee would be enabled to recommend a similar
policy to all members of the Association with
much more confidence. Before, however, taking
any steps towards having the idea put in force,
it was decided to send to the two Branches and
to the Dooars Planters’ Association copies of
Messrs Shaw Wallace & Co’s letter explaining
to them the Committee’s views and asking their
opinions on the feasibility of such a scheme as
that suggested. Messrs Shaw Wallace & Co.
were to be thanked for their letter and to be in-
formed of the action taken,

but in many of the islands this product is only
of secondary importance, while in others it is
ractically non-existent. I would suggest the
ormation of a committee to investigate and de-
termine the causes of the financial disability
under which the West Indies labour, whether
political, administrative, economic, geographi-
cal, climatic, or racial, and to correct any erro-
neous ideas which may exist in the popular mind

104 The Supplement to the Tropical Agriculturist
BRAZIL PRODUCTION OF COGOA.
Rio de Janeiro, Nov. 23.—Cocoa is one of
Brazil’s staple export products, and represents
for the State of Bahia what coffee does for Sao
Paulo. Its production is steadily increasing,
and, although no official or private statistics re-
cord the growth of the internal consumption of
cocoa, this is to a considerable extent confirmed
by the increased inter-state trade and the erec-
tion of new chocolate factories during the past
tew years. The State of Para ranks second in
the production of cocoa, followed by Amazonas
and Pernambuco, but the output of both these
States is small when compared with that of
Bahia, and atthe same time very irregular. In
1902 the production of cocoa in Bahia was
16,197,000 kilos, and since then it has steadily
increased, reaching in 1906 a total of 22,914,000
kilos. On the other hand, the production in
Para has gradually fallen from 4,372,000 kilos in
1903 to 1,752,000 kilos in 1606. In Amazonas
and Pernambuco production has been erratic.
In the former State the total in 1908 was
587,000 kilos, in the following year it rose to
over a million kilos, but in 1906 it fell to 357,000 —
kilos. Pernambuco, which in 1903 only pro-
duced 15,000 kilos, was credited with a pro-
duction of 114,000 kilos in 1905. In the fol-
lowing year, however, the total production de-
creased vy more than 50 per cent.
EXPORTS AND PRICES.
Official statistics show the following export
movement during the past five years :—
Kilos. Value.
1903 At 20,899,643 ofa £1,012, 224

48,794,498
4,880,000 f
53,674,498lb, = nearly 500,000 ewt. in 1907.
Notwithstanding the smaller clearances in
1907 when compared with those of the previous
year, it will be noticed that in value they show
a large increase, which is due entirely to the
sharp advance in prices last year. According
to official records, the current price of Bahia
cocoa in 1905 was Rs. $585 per kilo; in 1906,
Rs. $587; and in 1997, Rs. 1 $056. The average
price of cocoa in 1907, as compared with that
for 1906, shows the extraordinary increase of
Rs. $469, equivalent to 79-90 per cent.
France was at one time the largest purchaser
of Brazilian cocoa, but in 1906 she surrendered
that distinction to the United States, with
Germany second. In 1903 exports to France
reached a total of 8,294,000 kilos, but since then
they have shown a steady falling off, and in 1906
the total had declined to 5,283,000 kilos. Hx-
orts to the United States have increased from
5,263,000 kilos in 1903 to 8,894,000 kilos in 1906,
while shipments to Germany rose from 3, 122,000
kilos in 1903 to 7,190,000 kilos in 1906. Exports
to Great Britain in 1903 totalled 2,177,000 kilos ;
in 1904, 2,071,000 kilos ; in 1905, 1,250,000 kilos ;
and in 1906, 2,020,000 kilos.
During the first quarter of the current year
exports of cocoa amounted to 9,276,043 kilos,
which is an increase of 4,127,434 kilos (80°17
per cent) on the corresponding period of last
yoar. The average price of Bahia cocoa during
the first quarter of 1907 is officially registered as
$912 reis per kilo, and for the same period this
year as $903.
PRospKcrs OF THE INDUSTRY.
The prospects for this product are, on the
whole, encouraging, because consumption is
steadily growing and keeping pace with the in-
creased production. So far, its commercial
development has only been fostered by private
enterprise, but in view of the proposed coffee
propaganda scheme by the States of Sao Paulo,
Rio de Janeiro, and Minas Geraes, fostered by
the Federal Government, it would be well for
the Government of Bahia to take similar mea-
sures to advertise its principal export product.

THE SMYRNA FIG IN WEST
AUSTRALIA.
In August last the Department of Agriculture
coramunicated with the Commissioner of Horti-
culture, California, with a view of making ar-
rangements for the introduction of the Caprifine
insect of the Smyrna fig. Information has just
been received from Mr Ahrhorn, Deputy-Com-
missioner, San Francisco, that such arrange-
ments have now been made, that he will himself
attend tothe shipments on the Californian side
and that he will do everything to make them a
success. These insects are expected to arrive in
the course of the summer, and they will be for-
warded to the experimental station at Hamel,
where a plantation of both Capri and Smyrna
figs was established a few years ago. These trees
are now bearing, and ready for the insects. The
communication received from California further
states that the Blastophaga, which is the name
of the insect, was some time ago sent to Mr
Lounsbury, Government Entomologist, Cape of
Good Hope, and was successfully established.
Mr Lounsbury also writes to the department
that he will gladly supply insects as soon as pos-
sible. The Smyrna fig has a world-wide reputa-
tion, but, unfortunately, it has the peculiarity of
dropping before maturity unless previously ferti-
lised by the insect referred to, which winters
inside the Capri fig.—Westralian paper, Dec. 5.
SINGAPORE’S INCREASING TRADE
IN COPRA.
In reviewing the trade of Singapore for the past
year the Straits Times (Dec. 31) states that the
exports of copra continue to furnish satis-
factory returns, again showing an enormous
advance over previous years, and establishing a
record for at least the last half of a decade.
There is an increase of some 90,000 piculs
shipped to Great Britain and to the Continent
of Europe, the United Kingdom receiving
something like 63,000 piculs more than in 1907,
and the Continent of Hurope importing about
30,000 piculs over the quantity received last
year. During 1903, only 5,041 piculs of copra
were exported from Singapore to Great Britain,
and 581,251 piculsto Europe, while during the
year just closing the figures will be about 9u,000
and 85,000, respectively.

Improvement of Agriculture in Ceylon.
As we are leaving the colony in the
middle of February, and shall be away
for a year, we have thought it well to
put down some of the opinions at which
we have arrived upon this question, and
to complete the symposium by a paper
by Mr. Schrader, which appeared in the
‘‘ Independent,” and which is worthy of
eareful consideration.
While away we hope to visit Agricul-
tural Colleges, Experiment Stations, etc..
in Egypt, Italy, Austria, Germany,
Britain, the United States, and Canada,
and may be able to write occasional
articles upon them for the T. A. Incase
of anyone wishing to write as regards
any subject they may desire enquired
into, anaddress which will always find
us will be—Gonville and Caius College,
Cambridge.
We hope also, while on leave, to find
time to write the bulk of an elementary
treatise upon Nature Study, and the
outlines of Agricultural practice, for use
in Ceylon Schools.
ee
Agriculture in Ceylon and its Improvement,
By J. C. WILLIS.
Ceylon agriculture may be sharply
marked off into two classes—estate
agriculture and peasant agriculture.
There are great differences between
these in efficiency and result, and one
is liable hastily to generalise, and say
that it is all owing to the superior
industry and intelligence of the Huro-
who manage the bulk of the
former. That this is not entirely the
explanation, however much _ truth
there may be in it, may be seen
by omitting the European altogether
and comparing the native capitalist
or estate agriculture with that of the
villager.
peans
106
The difference is decidedly more
marked than in the countries of Hurope
or America, where the small agricul-
turist can often hold his own very well
by co-operation, against the big one,
without having to do as in Ceylon, live
on his own products.
To get at the real explanation, we
must analyse the whole subject. Before
progressive agriculture, 2. e,, agriculture
on other lines than ‘‘ grow what you
want, and consume all you grow,” can
go on, there must be satisfactory con-
ditions as regards what we may call
the preliminaries to agriculture,
The chief of these are land, climate,
soil, drainage, irrigation, cultivation,
crops, transport, capital and education.
Now land is plentiful enough, and
usually easily obtained or available in
Ceylon, and the climate is nowhere
unsuitable to the growth of crops, when
once the best crops have been discovered.
The soil is generally good enough, and
drainage and irrigation are sufficiently
attended to. Crops are plentiful, nearly
all of any value either existing in the
island from ancient times, or having
been introduced by the Botanic Gardens
in the last 70 years.
There remain then for consideration
transport, capital, and education, Now
the provision of transport facilities has
for very many years been regarded as
a eardinal point in British colonial
policy; in fact it has been expressed
in the form that the first element of
civilisation is roads, the second roads.
and the third more roads. Education
also has been liberally provided, and
with the extension of School Garden
work the necessary agricultural bias is
being given. Already, in districts where
there are such gardens, one sees many
new products or types of cultivation,
and on enquiry usually. finds that they
owe their origin to the School Gardens,
Later on, a more definite agricultural
teaching will be required in the higher
schools, but for the present the school
garden is enough.
There remains, then, practically un-
touched, simply the provision of capital,
and it is inthis that the great difference
between the capitalist ‘“‘ planter ”—be he
European or native—and the villager,
lies. The latter has steadily gone down
to a very low agricultural level—if in-
deed he ever were above it—and has
no capital at his back. Now, any agricul-
tural enterprise requires some_ capital,
for the land must be prepared and the
crops given time to ripen. If the culti-
vator have no capital, he must have
‘ yecourse to the local moneylender, and
from him borrow seed, or advances to
cover the period of ,waiting, or what
ff
[FEBRUARY, 1909.
not, or he must sell the crop before it
is ripe, of course at a great discount.
In actual fact, in about 80 different
places in which we have enquired, the
usual rate of interest quoted has been
50 per cent. The lowest was 40 per cent.
and the highest 75 per cent., but as the
interest was generally collected with
the principal, long before the lapse of
a year, these rates are really higher.
It is idle to gird at the moneylender
for such rates. His business is to get
what he can, and when the villager
can only give such scanty security, he
must pay high interest to indemnify
the lender for the risk. Were it easily
possible to lend at lower rates, one would
oxpery to hear of its occurrence some-
imes.
So long as the villager is thus help-
lessly in the grasp of the moneylender,
so long can he do practically nothing in
the direction of agricultural progress,
however willing he may happen to be.
When we add to this the general apathy
and inefficiency he displays, and what,
for want of a more accurate term, we
must call his indolence, it may be readily
seen that agricultural progress among
the peasantry of Ceylon is a thing to be-
hoped for, but not to be expected till the
clutch of the usurer is relaxed, and then
but slowly.
To endeavour to improve local agri-
culture, other than capitalist agriculture,
without taking the subject in proper
logical order, is to beat the air. One
man introduces good European ploughs.
Without capital the peasant cannot
afford such tools, while at the same time,
they make too violent a step forward to
be applicable. They cut through the
plough-pan of the paddy field, and let
the water out. Another man introduces
a new vegetable or other crop. Is the
villager to sacrifice crops, already yield-
ing a return, to experiment with some-
thing untried? He cannot doso with-
out more capital. A third man proposes
to teach agriculture in the village
schools. Whereare the trained teachers,
and how is the trained boy to apply his
knowledge unless he has money? Ifhe
bas money, and succeeds, his success
simply goes to emphasise the difference
already existing between capitalist and
villager.
Practically every improvemeutin agri-
culture demands money at the start,
though it may prove very profitable
later, and itis but rarely that it yields a
profit that will pay the Ceylon money-
lenders’ interest,
We may roughly represent the present,
and the possible, state of affairs by the
following diagram :—

'
108 [FEBRUABY, 1909.
Until the provision of all the items A
has been attended to, village agriculture
in Ceylon must remain at the low level
1. Given these, asthe people get out of
the clutches of the moneylender, it will
rise to 2, and then improvement in agri-
culture, properly so called, begins.
This improvement must be of the
most gradual kind, and every step must
be carefully tested by thorough experi-
ments before being recommended for
adoption, Improvement of cattle must go
hand in hand with improvement of the
tools they are to use, and with improve-
ment of their food supply, and so on.
This must suffice as a brief indication
of what we are convinced, after 12 years’
study, is the logical order in which to
attend to the improvement of Ceylon
agriculture.
Loans to Native Agriculturists.
Given that loans of money are to he
made, whether by Government or Agri-
cultural Co-operative Societies, to vil-
lage agriculturists, the question comes
up of how best to manage it, and how
to obtain good security, forin the case
at any rate of a Government loan, it
would be unsound finance to advance
against no security.
The essential features of the Raiffeisen
loan schemes (by means of local Agri-
cultural Co-operative Societies )—which
have been so wonderfully successful in
Europe, and are now extending in India—
are that the lending by any given soci-
ety is confined to the village where that
society is located, that it is managed by
a local committee who understand as
thoroughly as possible the financial
status and reliability of each borrower,
and that the liability is unlimited, so
that in the event of loss, it falls upon
each member of the society in propor-
tion to his holding.
The question then is—Can these prin-
ciples be applied to local conditions? We
are decidedly of opinion that the strict
localisation of loans should be carried
out. Let for each small district a local
committee be formed, with the Govern-
ment Agent as Chairman, and the local
headman as deputy chairman, and let
this committee be responsible for the
making of the loans, which must of
course be absolutely confined to their
own district.
The next item is the recovery of the
debt owed by the villagers. We would
suggestfor this the revival of the old
levy of 10 % of the crop. This is a tax
the villager well understands, and there
would be no grievance in its revival, if
done soon, while the outcry that might
be raised against its being reinstituted
asa tax would fall to the ground if it
were simply revived for repayment of
loans, Butas the least that could use-
. WILLIS.
fully be advanced to the villager would
be the value of his seed paddy—say Rs. 2
to Rs. 4.50 per acre—it is doubtful if the
10 % tax on the crop, which in many
districts is barely ten-fold, would repay
the loan with interest at say 123 %,
which must always be charged. We
would suggest a 15 % return or even
more in most cases, and where this
proved to be much too much, some
might be returned to the cultivator.
By this means the villager should in a
few years get sofar rid of the load of
usury that at present oppresses him,
that he might be able to consider the
question of actual ‘‘agricultural” im-
provement. Probably only a few at
first would in any case be willing to try
improved crops, tools, manures, or
cattle; but let these succeed and others
would follow.
Next as regards security for the debt.
We would suggest, as has already been
done by Mahawalatenne R. M., that the
greater headmen, as deputy chairmen of
the local committees, give security for
the amount to beadvanced. This they
will very commonly beable todo, and
if they are at first debarred from
advancing more than the value of the
seed paddy, while the 10% levy is
pledged for their repayment, there
should be no difficulty about this.
The 10 %, 12} % or other levy would
obviously not bring in exactly the
amount necessary for repayment, but
the figure should be fixed at the nearest
23 % above what is necessary; e.g., if
13 % were considered needful, repayment
should be by a 15 % tax.
In this way the local committee would
come into the possession of funds of
their own, and these might be again
lentin any way that seemed best to
them, adhering strictly to the principle
of local loans and unlimited liability,
and at an interest of say 123%. As the
Government is about to lend for paddy

cultivation only, these loans might be
for other or new crops (é.g., to start
sweet potato growing in the district), for
better tools(e.g., asociety might purchase
a disc harrow or other tool and lend it
out to its members), forsupply of manure
(by purchasing manure from Colombo
and advancing it to members, to be
repaid at crop time), for provision of
stud bulls, cocks, pigs, etc., for sale of
local produce in the Colombo or Kandy
markets, or for other purposes. But
the important thing at the commence-
mentis to get the villager. gradually
free of the exactions of the money-lender,
as has been explained in another place.
109
This must be done gradually, or a
new class, that of distressed money-
lenders, will come upon the scene, and
we would suggest beginning with the
advance of seed paddy only, against the
security of the headmen, through local
committees, the money to_be_ repaid
by a definite tax in kind upon the
p roduce.
We would confine loans at first strictly
to the ordinary villager, and decline to
advance any money to the richer
people, unless at so high arate of in-
terest that they could not profitably
lend it out again.
Agriculture in the North-Central Province.
By J. ©. WU£LLIs.
In this paper we are, of course, merely
taking the North-Central Province as a
type of the low-lying irrigable country
of Ceylon, which stretches from Ham-
bantota round the mountains to the
north to Chilaw, and these remarks will
apply to most of it.
This country is occupied by a very
small population (leaving the coastal
districts of Batticaloa, Jaffna, and Chi-
law out of consideration ), probably not
much over 200,000 in all, though the
area is over 13,000 square miles. or more
than half of the island. Now, in the
olden days of the Sinhalese monarchy,
this was the populous and wealthy
part of Ceylon, while the mountain
zone and the west—now the home of the
great tea, coconut, cacao, rubber,
and other industries—were a poverty-
stricken and neglected region.
Now, there is no reason why there
should not to-day be a great population,
and large industries, in this now desert-
ed land. The important thing is to
analyse the position carefully, and to
set to work in the proper logical order.
_ At present the North-Central Province
‘is largely occupied by a good-humour-
ed, fairly honest, but lazy Kandyan
population. By the opening of the irri-
gation works they have been practically
freed of the great amount of disease
which formerly devastated the country,
and have become, for villagers, fairly
prosperous.
Looked at agriculturally, they have
afew conspicuous faults. They waste
a great »mount of water upon their rice
crops, which they grow mainly in the
dry season with tank water. They cul-
tivate other things mainly on chenas.
They do not grow more paddy than
they want, and often leave the fields
bare for long periods,
Now the last-named of these faults
is one of character and temperament,
and cannot be easily altered, but the
two former depend mainly on the agri-
cultural conditions of the country.
A comparison of any other of the
outlying thinly populated districts will
show the same faults in operation.
There is evidently some general cause
forthem. They depend, in general, upon
the fact that in all such districts one
finds, uvon the whole, less capable and
less successful agriculturists, who live
as muchas they can upon the natural
capital of the country.
This natural capital in Ceylon is
simply land or soil, water, and forest,
The native of the North-Central Pro-
vinee, like any one else, has of course
taken the best land for his rice crops,
and to that there cannot be the slight-
est objection. He then, however, pro-
ceeds to grow his other crops largely
upon chenas, and for this he uses the
best land he can find, and ruthlessly sacri-
fices the other item of capital—forest.
After a couple of chena crops the land is
left to lie fallow in scrub fora good
many years before the process can be
repeated, There is neither need nor
space to go into details in a paper like
this, which is simply- giving a general
sketch without argument.
To turn now to more detail about the
other two faults mentioned, and first
the fact that rice is grown mainly with
tank water in the dry weather. The
Jaffna man who visits the North-
Central Province is at once surprised by
this; he, without tanks, and in a drier
country, must grow during the North
East rains. The ordinary unthinking
man puts it down to dislike on the part
of the villager to being out in the rain
or to some such cause. Experiment,
110 {Frprvary, 1909.
conducted at Maha-iluppalama, in the
North-Central Province, have shown the
true reason. Village rice sown broad-
east in a field simply supplied with rain
water has grown well enough, but has
become a mass of weeds, which cannot
be removed without great trouble and
damage to the crop. Whereas, if the
land is completely softened by the
rains, and well ploughed, tnen left to
soak, and kept always soaked, weeds
do not get much chance. This is the
real explanation. To improve on the
present methods sowing in the rains is
not enough. The land must be tilled
before the rains, and the crop must be
transplanted in rows, so that weeding
between can be carried out. This means
greater expenditure, in keeping the land
tilled all the year round, in transplant-
ing, andin weeding. This means capital,
which the villager has not got, so has
to live upon the natural capital of the
country.
Now turn tothe chena. The land is
cleared of trees, up to acertain size and
burnt off. Before the weeds begin to
grow, the crop is thickly broadcasted on,
and gives a good return on the fresh
forest land. But the weeds grow, and
it only occasionally happens that the
villager can afford, from his indolence,
enough labour to partially clear for a
second crop, which of course is not so
good as the first. The land is then allow-
ed to grow up in scrub, which keeps
down the small weeds, and after a few
years can be again cleared at far less
eost than weeding would involve, while
it has had the advantage of a kird of
fallow.
Land which natives and Kuropeans
alike said was only fit for chena is now
being continuously cultivated at Maha-
iluppalama and _ yielding good crops.
But without capital, which is the un-
derlying secret of success there, the
villager of the North-Central Province
is as helpless asa baby to do anything
but chena, as he is helpless to grow rice
with the rains, and he must not be
blamed for his present methods.
Another point about chena is the
effect on the soil. To keep the natural
capital of the soil unimpaired, either
rotation, manuring, or chena must be
practised, and as a capital is wanted for
the two former (as has already been
indicated) the last is the only possible
resource.
We have now to consider the problem
of what is to be done to get_the inhabi-
tants of the North-Central Province out
of this state of things. If left as they
are, progress will be as it has always
been—very slow. With the opening up
of the country by transport facilities,
capitalists will gradually be attracted
into it, but the villager willnot progress.
It therefore becomes a question whether
attention is to be devoted wholly to the
capitalist, or whether the villager, and
people like him, are to be helped also,
and whether they are to be directly
helped, or assisted to help themselves.
The latter is what we personally vote
for, but this question is one for the
Government, and has only to do with
agriculture in that its solution is an
essential to progress in the latter.“ In
the old Sinhalese days, it is probable
that the villager was at least upon as
low a level as at present, and the kings
helped them by compelling them to
make tanks, which greatly increased the
natural capital of the country, by
making water available at any time,
instead of only in the last few months
of the year.
Whiletheoretically, no doubt, it would
be better to aid the villagers already
existing in the North-Central Province
to supply themselves with capital, im-
PIONS their agriculture, and take up the
alance of the available land, in practice
this would take centuries, and is too
long to wait.
The villager should be settled upon his
own land, and a sufficient area reserved
about him, which he will at first of
necessity chena, but which he will, as he
gets more free of the money-lender, gra-
dually be able to lay down to permanent
cultivation. Now,there is little doubt
that he is so indolent that he would
prefer to go on indefinitely upon the
present lines, and compulsion must be
brought to bear upon him. We would
suggest that, provided he has been sup-
plied with the means of getting cheap
capital, the chena area be reduced by
25%, say, every sixth year, till he has
only 25% left. He will thus be compelled
to lay down, the land to permanent crop-
‘ping. We would attach the chena area
to the village as a whole as common land,
and stipulate that part of it have the
trees sufficiently thinned out to cause it
to form good pasturage, and of course ©
make the area large enough to allow of
room for other crops when the necessary -
proportion of the 25% remainder was
given to pasturage, In this way the
chena difficulty might be gradually got
over. At present the villager must
chena, but the land will stand per-
manent cropping.
It must be rememhered that for annual
crops—which are much better suited to
the small capitalist than perennials, such
as rubber or tea or cacao—the chena
land must be irrigable. Pasture, on the
other hand, need not he so,
FEBRUARY, 1909.)
We would suggest, as he becomes
more free of money difficulties, gradually
curtailing the amount of water allowed
to the villager for his rice land, and the
upplication of some at least of the saving
to his ‘‘common.” So long as_ the
present rate of water consumption is
allowed, so long willit be impossible to
Open up any seriously larger extent of
country. Water must be available
before land can be opened.
Experiments should be set on foot to
determine the minimum water that can
be allowed to the villager. They should
then be limited, at first to say 25 % more
than that, and the amount gradually
decreased, thus setting more water free
for other land.
The local villagers being few in num-
bers, lazy, and improvident, other
people should also be induced to settle,
and here comes 1n another very import-
ant consideration. The newcomers
should be settled in entire villages of
one race or caste, and by the mixing of
peoples thus brought about, the general
standard of living will be raised, and
some variety introduced into the local
agriculture. At the same time, among
the villages thus formed, blocks of land
should be reserved for capitalists, and
land in them only sold in large pieces.
In this way the villager will have object-
lessons at his door, and the capitalist
village labour.
Every village thus formed should be
given some common land, part of which
should be devoted to pasturage, part to
crops that can be marketed elsewhere,
i.e-, in general the crops that can be
11,
sold to the local capitalist estates; and
a definite water supply should be allotted
to the common. Communal tools might
also be obtained by co-operation among
the villagers, or by a 10 % tax on the
produce.
In laying out the villages, they must
be divided by road reservations, in
which, as_ traffic increases, actual roads
can be made, though at first mere clear-
ing of the track (pin-para) would suffice.
This is very important. Transport faci-
lities are one of the indispensable preli-
Minaries to progressive agriculture.
There remains then the attracting of
capitalists. Just as with the villagers,
the first to come are often small ones
crowded out of other parts of the
country. To attract these is something,
but more rapid progress will be made if
larger can be also got to come. The pre-
liminaries of land, labour, transport,
and, above all, guaranteed water supply,
must be carefully attended to, and
capital will then be attracted to grow
rubber, coconuts, cotton, and other
things. Under some of the tanks the
land should be saleable only in large
blocks and no small holders allowed.
This will serve as a brief indication
of some of the lines upon which we
would propose to work, and a careful
consideration of the whole question
during this year will be time well spent.
The general lines we have been laying
down are developed at greater length in
a book upon “ Agriculture in the Tro-
pics,” to appear within the next few
months, and which those interested in
tropical agriculture may find of interest
to study.
The Teaching of Agriculture and how to Teach the People.
AN OBJECT-LESSON FROM AUSTRALIA.
In my article on “The Improvement
of Cattle in Ceylon,” I made the follow-
ing statement: ‘‘ There is no doubt that
ocular demonstration is of far greater
importance than preaching, especially
when dealing with the ignorant masses.
This must be taken full advantage of in
driving out the prejudices and lax
methods of the psople.” This shail be
my text for this article, and I feel certain
that it is the only way of starting to
improve the obsolete and ignorant
methods of the people. We know that
the most approved methods of the
present day of teaching infants is by
means of object-lessons. In the same
manner the only way to teach the grown
up ignorant agricultural infants is by
the same methods. NowI will forma
short resumé, as farasI know, cf what
has been done in the past. A School of
Agriculture was started in Colombo
under the able guidance of a graduate
of an English Agricultural College, but
it was a failure--why? In the first
place the country (was not ripe
enough for an = institution of that
nature, the right stamp of students
were not attracted, and most of those
that came there came to receive a
112
cheap education, and on leaving the
institution they turned to every walk of
life—except agriculture, We know that
once the son of a village ‘“‘gamarala”
dons a pair of trousers and a coat, he
does not care for his village life. In the
second Place Colombo or any city isin
no way adapted for an Agricultural
school. Rural work °
MUST BE CARRIED ON AMID RURAL
SURROUNDINGS,
where there will be sufficient land for
the actual carrying out of agricultural
operations in every branch, the students
playing the principal part. The late
Colombo School of Agriculture did not
apparently pertain to teach practical
agriculture, except in the form of
cultivating a few vegetable plots, which
was absolutely valueless. The next
thing was agricultural education in
the form of School Gardens. They
are no doubt excellent in their way
and for the object in view, but
not of sufficient weight by them-
selves, to reach the mass of agricul-
turists. Then we had the starting of
the Agricultural Society by Sir Henry
Blake, our late Governor. The Society
publishes a very good journal, holds
monthly meetings at which are read
numbers of valuable papers, etc., and
also have around it numbers of branch
societies doing similar work, but the
main object, that of reaching the agri-
cultural masses, is lost sight of. Now we
are coming into a new era under our
progressive and practical Governor who,
no doubt, willdo his best to give us
something that will reach the masses.
In starting agricultural instruction and
development in CeylonI do not think
wecan do better than be guided by
what has been done in other countries.
As I am able to speak with some
authority on
WHAT HAS BEEN DONE IN AUSTRALIA,
having had the opportunity to spend ten
years there, all the time actively
engaged in agricultural pursuits, I will
refer to what has been done there. The
agricultural masses of Australia were
at one time ignorant, as far as modern
scientific agriculture was _ concerned.
They ploughed and sowed the same
crops year after year on the same land,
and could not understand why the land
would not produce the same quantity
of grain per acre asit did years back.
They used no modern labour-saving
appliances. They could not understand
that rotation of crops, green fallowing,
artificial manuring, the proper treat-
ment and application of farm-yard
manure, etc., would be beneficial and
would be their salvation, They looked
[FEBRUARY, 1909.
down on scientific cultivation which
they called ‘“‘new fangled ideas.” The
Government had a hard task to perform,
but they went aboutitin avery prac-
tical way. They started establishing
experimental farms right in the heart
of great agricultural centres. These
farms were Zhuge object-lessons, Land
similar to that worked by the farmers
was cultivated under ‘“‘new fangled
ideas.” Everybody, of course, was
curious to see the result, while at the
same time being certain that the whole
thing would be a failure. By and by,
as time went on, some of them started
visiting the Government farms, and
were shown round by the managers who
took the opportunity of explaining the
why and wherefore of things being done,
told them of the number of bushels per
acre the lust wheat crop yielded, ex-
plained the methods adopted in making
farmyard manure, the amount of labour
saved by the use of certain implements,
etc., etc. The visitors went back and
pondered over
WHAT THEY HAD SEEN AND HEARD
and naturally talked about it to their
brother-farmers, who, in their turn,
visited the farms, and so on, and so on.
Later on the majority came to the con-
clusion that there was something in
these ‘‘new-fangled ideas” and went for
help and advice to the managers which,
of course, was most readily given, and
gradually modern methods began to be
adopted, the farmers finding that by
their adoption the crops were doubled,
and that the use of labour-saving ap-
pliances put more money into their
pockets. The experimental farms then
started taking in afew students, as the
farmers wished their sons to receive
modern training, and, of course, the scope
of these farms only permitted practical
agriculture being taught. As things
went on the time became ripe for the
stablishment of Agricultural Colleges
where a student could receive both
scientific and practical training. In the
State of Victoria, where I spent most of
my time, the first College started was
the Dookie Agricultural College, where
I graduated. This College was, first of
all, an experimental farm, then an experi-
mental farm with a few students,
and lastly an _ Agricultural College.
It had attached to it 4,700 acres of
land, and only received, while I attended
it, forty students. Since then the
number of students has beer doubled.
At this institution every kind of tarm-
ing was carried on and taught, the course
being two years. A student in case of
failure to pass examinations was allowed
a further year, bit at the expiration of
that period had to leave. The

STUDENTS WHERE DIVIDED INTO FOUR
CLASSES,
two junior and two senior—one junior
and one senior being out working on the
farm every day, while the other two
were attending lectures, the subjects
comprising the breeding of horses, cattle,
sheep, and pigs, irrigation, drainage,
arboriculture, ensilage-making, the grow-
ing of serial crops and their man-
agement, Chemistry, Botany, Geology,
Zoology, Entomology, English, Natural
Philosophy, Book-keeping, Surveying,
Horticulture, Viticulture, Apiculture,
and Olive-oil making. Four professors
lectured on these subjects, while there
was a separate outdoor staff to teach the
practical work. The outdoor working
day consisted of eight hours, the stu-
dents actively carrying out all the dif-
ferent farm operations, the staff only
teaching and seeing that the work was
properly done. Every season about 500
acres were put under serial crops and
about 60 under silage crops; vineyard
work was carried on, and wine made from
80 acres; dariying was carried on, about
twenty-five cows being milked daily, the
milk being turned into butter and
cheese; olive oil was made; orchards
were attended to; about 4,000 sheep
were shorn; pig breeding was carried
on, and poultry’ received atten-
tion. Large experimental plots were
worked. Black+smithing and carpentery
were taught, all repairs to machinery
being done on the place. Other farm
operations too numerous to mention were
earried on. All this work was done by
the students, and done well, and the
farm paid its way. When a student
finished his course and went out into the
country, he was a power in the land, he
was a thorough master of his profession.
Later on Victoria found it necessary to
open another College. The other States
started on similar lines, and all of them
have now large flourishing
AGRICULTURAL COLLEGES AND
EXPERIMENTAL FARMS,
yearly sending out young men to teach
and to work for the country’s good and
their own. It was by ocular demonstra-
tion, by means of huge object lessons,
that Australia the great Agricultural
continent started teaching her sons
modern, scientific agriculture. And I
think my readers will agree with me
that this is the only way it can be done
in Ceylon. Ofcourse we don’t want 4,700
acres of land; 100 acres with some paddy
Jand would suffice for our experimental
farms. Too much stress cannot be laid
on the choice of the men who are to
manage and work these places, as on
them and on them alone depends the
13
118
success of the undertaking. Personality,
ability, education, a thorough mastery
of practical work, and men not ashamed
to take off their coats and show the
people how certain operations have to
be done, all these essentials must be
embodied in those who are to have in
their hands the future destinies of the
improvement of agriculture in the
Island. Soon we shall find, as Australia
did, that the masses who are by nature
agriculturists will take interest in the
object lessons, and give the new methods
atrial. Once they do that and find it
paying they will naturally enlarge their
scope of operation, and will, in a short
time, come to the conclusion that there
is money in new methods. They will
then want their sons taught the new
methods, and, by and by, when these
sons are turned out of the experimental
farms and work
THE LAND OF THEIR FOREFATHERS,
they will find more money coming in.
Their training will have taught them to
work to the very best advantage, and
when these young men in_ their turn
have sons of their own old enough to
receive agricultural training, %.e., about
16 years of age, during which time they
received a good elementary education,
then will be the time for Ceylon to open
her first agricultural school, and in time
turn out, as Australia is doing, hundreds
of young men yearly, who will ‘‘ go out
into the land and make it bring forth
fruit abundantly.”
THE SCOPE OF EXPERIMENTAL
FARMS,
In the foregoing article I suggested that
“100 acres of high land with some
paddy land would suffice for our experi-
mental farms.” The question will arise,
“What is to be done on these lands’?
In other words, in what form are these
object-lessons to be placed before the
grown up agricultral infants of Ceylon ?
Itis important that these farms should
be worked on business-like principles, ~
Everything done should be within
the scope of those who are to be
taught, and induced to adopt the
new methods. The produce must be
commodity, and must
show profit. Otherwise the farms
would be useless. They must be worked
with economy. A strict account of ex-
penditure should be kept, so that the
actual balance after the sales can be
made public. A great object-lesson is
to show the people how much money
these new methods will put into their
pockets. The following is a
LIST OF THE IMPLEMENTS, ETC.,
a marketable
114
necessary for each farm :—
One “forest devil” or stump extractor,
three ploughs for high land, three
ploughs for paddy land, two sets of
harrows, one roller, six hay forks, one
paddy-field_ leveller, one hay knife,
one paddy-threshing machine, six long-
handled shovels, three scythes, two
double bullock carts, one ‘planet
junior * single cultivator and three pairs
heavy draft bulls.
THE QUESTION OF PADDY CULTIVATION
—how to grow more paddy than is now
done—should be brought home to the
villager. It is a question that appeals to
most people when the greatly increased
cost of rice has to be considered. It is
a question that the planters would like
to see solved, as it touches them sorely
when they have to retail rice to coolies at
less than cost. In fact, it is a national
question and worthy of the attention
of Government. We have the land, and
it only requires proper cultivation. to
bring about the necessary results. The
Government is yearly spending large
sums of money on irrigation works. Of
what use are irrigation schemes if the
greatest question of all—that of teaching
the people to make the land productive—
is left untouched? The paddy land of
the farm should be entirely fenced in
and judiciously subdivided so as to en-
able cattle to be run on the stubble
without interfering with other cultivat-
ed portions. The plough must be light,
but able to turn soil to at least a depth
of four inches. It must have two handles
and one pole. It is absolutely impos-
sible to do good work, i.e., cutting and
turning over every inch of the soil with
straight furrows at an even depth with
even the English-made ploughs sold in
Colombo with one handle and a pole,
asthe pole makes the plough far too
sensitive to every movement by the
cattle, and with one handle it is im-
possible to steer it. The ploughs should
have the usual beam as used for horses,
to which should be hooked ona chain
to take the place of the pole, and to the
end of the chain the yoke. In these
matters I am nottheorising but speak
from personal experience. The ordi-
nary native plough is, of course, out
of question as it does not plough but
scratches the surface. The first process
of preparing land for paddy is to repair
the bunds and clean out the channels,
for which work I would introduce the
long-handled shovel mentioned in my list
of implements to take the place of the
Ceylon mamotie. The shovel does the
work sooner and better, and is a far
handier tool to use. The fields should
then be inundated and the water allow-
ed tostand a sufficient length of time
‘Se =a eae eal 41 | ce) ple ee
(FEBRUARY, 1909.
to killthe weeds. After this the water
should be turned into other fields, and
when the land is sufficiently dry, plough-
ing should commence. The ploughman
should turn upthe soil toa depth of
about four inches. If necessary it might
be cross ploughed. The land should next
be levelled and the seeds sown. I am
not a_ believer in the transplanting
process, advocated by many, but itis
entirely a question of “will it pay?”
If it does, certainly do so. But I believe,
if the two-handed system of sowing is
adopted, as is done in sowing’ wheat in
other countries, transplanting will not
be necessary. This and other matters
the experimental farms should very
soon solve beyond question. Once the
seed is sown and until harvest time
judicious irrigation where possible is
about all that is necessary. In the
matter of harvesting scythes can be
very well used. A man can do four
times as much work with a scythe as
can be done by the small sickle now
used, except on land where water is
lying and it would not be judicious to
wet the heads. The introduction of
hay forks, and a threshing machine
will, with the greatest deal of economy,
and in the shortest time, have the paddy
in bags ready for market. It is out of
the question for every man who culti-
vates paddy to own a_ threshing
machine. But, as is done in other coun-
tries, once these machines are found
to pay, travelling machines will do the
workatasmallcharge. There are other
matters which will have to be attended
to as they turn up—judicious manuring,
bare fallowing, and, if possible, the
growing of other crops, forage, etc.
DRY GRAIN CULTIVATION.
For this and other work to be detailed
later, one hundred acres should be felled
and burnt off after securing sufficient
timber for building and fencing purposes.
The land should be fenced and sub-
divided into paddocks of twenty acres.
All the stumps should be extracted.
This is a most difficult and expensive
operation. It can, however, be done
cheaply and expeditiously and quicker
with the ‘‘ forest devil” mentioned in my
list of implements. The subdivision of
land is necessary for running cattle on
the stubble or feeding off green fallow
cecops, etc. The villager usually cultivates
some dry grainonchenalands. The land
is lightly hoed and the seed scattered.
The result naturally is very poor. He
also has a belief that the land can only
be cultivated for about three seasons.

land year after year, if he cultivates the
land properly and follows out a system
of rotation of crops, with judicious green
manuring, ete. The land on the farm
must be ploughed to a depth of at least
four or five inches. The plough used for
the work must be of a little heavier type
than that used on wet, clayey paddy
land. After ploughing the harrow is put
on which will stir, pulverise and level
the land thereby making a good seed-
bed. The roller will then follow. With
regard to the effect upon the crop of
pressing the soil about the stems and
roots of the plants, all who are familiar
with gardening works know. The plant
cannot grow well if the soil does not
support it in a fixed_ position, while
alternating rainy and dry weather will
draw the soil away and destroy the
close relation between soil and plant
necessary for the process of vegetation.
lhe roller counteracts this and
establishes close contact between soil
and stem and roots. The _ seed is
now sown and covered. Once the plants
have established themselves and attained
a certain height, the harrow is put over
the growing crop, This loosens the soil
thereby breaking up the capillary tubes
and minimising evaporation. The har-
vesting could be done in two ways either
with a reaping machine orascythe. I
would not suggest the reaper as it would
be very injudicious with the object in
view to introduce anything that the
villager cannot buy or improvise. So
far the only expensive implement he
will have to procure is the plough. A
serviceable set of harrows can be turned
out by a village blacksmith, and a_ very
good roller can be made out of a log of
wood. Ploughs should be sold to vil-
lagers at cost price to be paid for by in-
stalments. As years goonand the people
become more prosperous and have learnt
the first lessons of the utility of modern
implements, then can be introduced seed
drills, reaping machines, disc harrows,
threshing machines, etc.
CATTLE,
The experimental farms can be run in
conjunction with the ‘‘Stock Farm” sug-
gested in my article on ‘‘ The Improve-
ment of Cattle in Ceylon.”—vide page
57 of last issue. A certain number
of cattle are necessary for economic
purposes. There is always the stub-
ble to be utilised and crops vnder
green fallow to be fed off. It is neces-
sary to have draft power available. The
raising of cattle would also show the
people the economy and profits of mixed
tarming.
PIGS AND PIG BREEDING.
We all know the difficulty of procur-
ing a good piece of pork, so much so, that
115
wherever a good pig is secured for
butchering, it is specially advertised
in the papers. Why should not good
and cheap pork be always available ?
At present, except by a few individuals,
pig breeding in any systematic way is
unknown. Two pairs of pigs, one of
Berkshire and the other a Poland China,
would suffice for each farm.
circular holes with a diameter of
from 6 feet to8 feet and from one foot
to 18 inches deep. Some think it neces-
sary to sprinkle salt on the surface
after planting, others salt and ashes,
etc., etc. In weeding some believe in
clean weeding ; others let the weeds grow
up and weed once a year; yet others
adopt a middle course, between the two.
Some bury the weeds with the fallen
coconut leaves in large trenches between
the rows of trees ; others burn the leaves,
weed, etc., and sprinkle the ashes round
the trees ; while some mix theashes with
manure, ete, ete. In cultivation some
turn up the entire soil; others turn the
soil round the tree to an extent of 6 ft.
from the base leaving a space of one foot
at the base; others again leave 18
inches and two feet at the base
and turn up 7 feet, 8 feet, ete. In
manuring with cattle manure some

when able, i.e-, when there is rain.
Others don’t trench. They tie theeattle
and turn the soil when able. Some tie
two head of cattle fora week; others
for lesser or Icnger periods, ete. There
is also a diversity of ways in the
application of artificial manure. Some
do not believe in it at all; some spread
the manure on the surface and turn the
soil, the space left at the base of the tree
varying from one foot to two feet, ete.,
and turning up from 8 to 9 ft. ete. Some
trench round the tree and apply the
manure. They

and replace the soil that has been
removed; others leave two feet at the
base and dig a trench a foot deep and a
foot wide, put the manure into it, and
cover. Someuse forks, others ply the
mamotie, and so on. There is also a
diversity of opinion and method in sup-
porting bunches, In picking the crops
some use long bamboos with a knife
attached; others insist that the men
should climb the trees jand pick the
nuts, etc. In turning the nuts into copra
even some large proprietors entrust
thousands of rupees worth of produce
to badly constructed and the most
inflammable of drying sheds, storing the
dried material in stores of a primitive
and inflammable nature. Surely each
and all of these methods cannot be right
and yet wrong. I will now give
AN ACCOUNT OF THE METHODS
I HAVE ADOPTED
and my reasons for doing so,andI only
hope others will do the same for mutual
benefit. I by no means contend that my
methods are theright ones. Hight years
ago I took charge of a coconut property
of over 600 acres, without any previous
experience in coconut planting, trusting
to my scientific training, knowledge and
experience in agriculture and horticul-
ture gained in Australia, and also hop-
ing to learn the methods adopted by
others. But, to my great surprise, I
found that there was no fixed principle
or method employed. No two planters
even under similar conditions of soil
and climate adopted the same method.
There is no doubt that all cultivators of
the coconut and other palms are to a
great extent moving as it were in the
dark, as there is no scientific data to
work on, no records of research as a
guidance. All that can be done at
present is toapply scientific data_estab-
lished for general agricultural and horti-
cultural purposes in other countries,
combined with what experience itself
has taught us. But what I contend is
that even this little has not been done
in any systematic form as far as the
coconut tree is concerned.

NURSERIES.
For this purpose I trench the soil to a
depth of 2 fc. T dig and throw away
from the land to be trenched 2 ft. « | ft.
depth of soil; then L dig up the remain-
ing L ft.; another 2 ft. of surface soil
adjoining is dag up to a depth of 1 ft.
and throwu into che previous tren zh,
and the bottom of this new trench is
turned up to adepth of 1 ft. and soon
until completed. At the end there will
be wanting 2 ft. x 1 ft. depth of soil,
which is replaced by the first spadefuls
of soil that were thrown out. I adopt
this method as all young plants require
a good free depth of soil to enable the
young roots to easily make their way
in search of food. For, as J stated in a
previous communication, a soil well tilled
makes the dormant plant food, by
means of nitrification, and by other
chemical changes that take place by its
exposure to atmospheric influences, more
available and in a soluble form to be
easily taken up by the young plants. If
the young plants receive any check it
retards their growth, and once dwarfed
they never entirely recover. For plant-
ing I chose the best round nuts from
trees about 380 years old, the nuts being
from those bunches that are ripe at the
time of picking. I plant the nuts stalk
end up, leaving about half aninch out
of the ground and a space of 18 inches
between them. At every third row I
allow a pathway 2 ft. 6 inches wide for
the purposes of subsequent weeding and
watering. I now cover all the seed beds
with ordinary dry coconut leaves to
prevent the direct rays of the sun acting
on the part of the nut above the surface
and also as a mulch for conserving
moisture. lalso keep the place weeded,
and water it at intervals during the dry
months. The distance of 18 inches
between the nuts [ consider necessary
as feeding room for the young plants,
as well as for a free circulation of air
so necessary for the well-being of all
growing and living things. Watering
Cl consider necessary to make the plant
food soluble and to prevent any re-
tarding growth. The results I find
highly satisfactory.
PLANTING.
In laying down the plants in the field
I place them 27 ft. apart as being some-
thing betwixt and between the various
distances generally adopted. I also eon-
cluded from personal observation that
it gave sufficient feeding ground for
the roots, as well’'as air and light so
necesSary for vegetation. The coconut
holes are 4 ft. square at the surface,
graduating down to 3 ft. square at the
bottom. The depth of the hole 8 ft.
For the purpose of getting through the

work fast and being accurate, I make a
number of light frames of the top and
bottom sizes, which enable the men to
mark out in the first place a proper
square that would be at right angles to
the holes that have been dug, and the
ones to be dug, and the 3ft, frames would
guide them as to the accuracy of the
bottom. In low lying land the holes
are cut to various depths, from 1 ft.
2 ft. 6 inches, and in some instances the
nuts are planted on the surface. This
land I subsequently drained, throwing
the earth up and thereby raising the
land where the trees were planted.
The drains at the same time drew away
all superfiuous moisture.
THE YOUNG PLANTS
are carefully dug out of the nursery
taking care that only the best plants
are taken up, and any broken’ or
damaged roots trimmed. One _ foot
of surface soil is, returned to the 3
feet deep holes, and in it the young
plant is placed and staked, taking care
that the soil round the plant is firmly
tramped down, leaving just the top of
the nut showing. The soil I was dealing
with was asandy loam with a good free
gravelly sub-soil—there being in most
parts of the land 3 to 4 feet of good
surface soil. There is no doubt that one
must be guided by his soil and sub-soil
as to the depth of planting. As for
example, if the sub-soil is one of cold
clay which is as a rule impervious to
water, and is not physically fit for
planting, if it has tobe planted, surface
planting is the only way, backed up by
a thorough system of drainage.
WEEDING.
On the subject of eradicating weeds I
was taught (Ist) not to allow the weeds
to go toseed, (2) tostudy the nature of
the plant, (3) not to allow any plant_to
breathe too long, (4) to weed clean. No.
1 needs no explanation. No. 2 is very
important as some plants wili die when
cus at surface level, while to others
surface cutting will act as a pruning and
will make them grow better; others
again grow from cutting. So each has
to be treated according to its nature.
As regards No.3 the leaves being the
breathing pores of the tree the constant
cutting down after the weed was grown
to about 5 inches, weakens the consti-
tution of the plant and in times it dies
out. This has been done with great
success in Australia, where it was found
impracticable to root out certain weeds
on very large areas, No. 4 is equally
important, as by careless weeding one
cannot eradicate weeds, as the plants
left will run to seed and the seed become
plants before that portion has its turn
again. I applied these methods according
[Oils and Fats.
to the nature of the weed [ had to deal,
with the result that what was a very
weedy estate became practically clean.
I do not approve of burying the coconut
leaves, etc., in trenches in the middle of
the rows, as I consider that the expense
would be greater than the _ benefits
received. Dry vegetable matter as a
rule does not contain any valuable plant
food except potash. I chop up the
leaves with mamoties and burn them
with the weeds in suitable heaps, and
scatter the ashes around so that the
potash would percolate into the soil by
the rain.
CULTIVATION.
I was taught, and experience has
proved, that intense culture with deep
cultivation is necessary for successful
fruit growing, for the reason, (1) that
the feeding roots could travel easily
without resistance in search of food; (2)
that it meant-anaccess of airso neces-
sary for nitrification and for other
chemical changes that would take place
by atmospheric influences, etc, by which
means the dormant plant food becomes
available ; (8) that it meant the reserva-
tion of moisture by means of breaking
up the capillary tubes in the soil and
thereby minimising evaporation; (4)
that it prevented the washing away of
plant food as the rain would penetrate
into the ground instead of running
away. Ifound that I could not carry
out all these principles on the coconut
estate, so [I set to work to adopt as much
of them as possible. I found that the
soil had been turned round the trees in
certain portions, tothe extent of 5 feet
leaving one foot at the base ofeach. For
the first wet. season I continued this
system, as my labour conditions, etc,
would not permit anything more. The
next season I left 18 inches at the base
of the tree, and turned the soil 7 ft.
round thetree. I later on increased it to
8and 9ft., my object being to continue
increasing so that ultimately the two
circles of the opposite trees would meet,
and the entire
FEEDING GROUND BETWEEN THE TREES
be cultivated, The cost of turning
soil 9 ft. leaving 18 inches at the base
was a little over 2 cents per trees as
a cooly could do 16 trees a day, wages
at 388 cents per day. I imported a
splendid double farrow plough from
Australia which I worked with a team
of four buffaloes, but asthe buffaloes
required too many men to drive, and «as
they could not be worked during the
hotter parts of the day, I hired an
elephant paying Rs. 5 per day, and, feed-
ing it on coconut leaves, I found that
with the elephant 1 could plough four
acresa day. The heavier soils require

more cultivation than those of a sandy-
nature. In the same way sandy soils
would be injured by too much cultivation.
MANURING.
1 found the practice in existence of
tying during the nights two head of
cattle a week toeach tree, ina basin 5 ft.
round the tree. This was done right
through the year, and when the wet
weather came on, the soil in the basin
was turned up amamotie depth, and
the soil which had been originally in the
basin was put back. There is adiversity
of opinion among the highest agricul-
tural authorities as t> whether fresh
dung is better than decomposed farm-
yard manure. High authorities dis-
agreeing, each having good reasons for
and against, I came to the coaclusion
that both systems are good if properly
adopted. So during the wet weather,
and as long as the soil was moist enough
fortucning, I tied two head of cattle a
week toa tree, and atthe end of that
period turned in the manure after dis-
tributing it in the basin, and returned
the soil taken away by ‘‘basining.” At the
same time I turned up another 8 ft. of
soil outside this radius. But tying the
cattle to trees during the dry weather
and waiting for the wec weather to
turn the manure into the soil, did not
seem to me at all correct, for by that time
all the valuable properties, or most of
them in the manure had evaporated, and
all that remained was a hard mass more
fit for fuel than manure, which when
buried would not decompose for years.
BY THE SYSTEM OF BASINING
also a large number of trees would
receive material injury, for in the fisrt
place a great number of feeding roots
are cut away which in itself gives a shock
to the tree. Then the cattle tramping
in the basin for a week solidifies the soil,
thereby increasing evaporation and
also preventing the below ground feed-
ing roots having easy access in search
of food. I constructed some
MANURE PITS WITH A ROOF
in different parts of the estate, so
that the material would be as close as
possible to the land to be manured. I
tied two head of cattle to trees in the
neighbourhood of the pit, and every
third dayI had the dung collected by
women and thrown into the pit, taking
the precaution to sprinkle a sufficient
quantity of kainit to prevent the loss of
nitrogen. [ changed about using the
trees, as farasI could, taking care not
to get too far from the pit. This was
done with the object of allowing the
liquid manure in the form of urine to
benefit more than one lot of trees. I
also carted to the pit any straw or other
waste material that would decompose
[FEBRUARY, 190d.
and form manure. When the wet
weather came I carted the manure from
the pit to the trees to be manured,
spread five ordinary garden baskets full
round each tree, and turned the soil to
a distance of 9ft. I used cattle manure
once, and the next time artificial for
reasons given in my article on “ Artificial
and Farmyard Manure, ete.” In the
application of artificial manure I had to
be guided by the amount of money I
was allowed to spend for manuring, so
Iecould only apply the two principal
necessities—phosphorie acid in the form
of bone dust, and nitrogen in the form
of castor cake, at the rate of 3 lbs. of the
former to 6 of the latter. I got the two
manures separately as it is cheaper that
way than buying the mixed, The cooly
measured the two and mixed them up
before use. I spread the mixture on the
surface over a 6 ft. radius leaving one
inch at the base of the tree and turned
itin. Then 1 turned over another 3 ft.
outside this radius without manure.
Later on, I sprinkled as much ashes as I
could possibly collect around each tree
to supply the necessary potash.
I give below an

The reason for applying a large per-
centage of kainit was to supply sodium
chloride (common salt) to the soil. This
I think of great importance to lands
away from the sea. Kainit contains
over 30 per cent. of salt.
A cooly could easily manure twelve
trees per day, 7.e., measuring and mixing
the manure, spreading, turning in the
manure toa6 feet radius, and turning
unother 3 feet outside this radius; this
means, wages being at 33 cents per day,
that each tree costs a little less than
8 cents. Turning the sods competely
over thereby burying the grass and
manure, I consider very important.
This is easily done except on estates of
a sandy nature, by removing the first
lot of sods and turning the second lot
into the trench, working from the base
of the tree to the outer. I also found
that two or three coolies turning the
soil at one tree simultaneously could do
better work, and the work does not seem
so tedious, as one cooly working at each
tree by himself.
PLANTING VACANCIES.
I had to do this ona large scale, as on
taking a census of the estate I discovered
that there were about 3,500 vacancies,
and as [ had over 200 head of cattle to
protect the plants from, I adopteda
method that.had been carried on before ;
that of using husks stacked up around,
asafence. I found this an excellent plan,
as it not only acts as a fence but as a
mulch in conserving moisture. I carted
five cart-loads of husks to every vacancy
and had them stacked round the holes
when convenient. When the wet
weather came I planted. Results were
astonishing, and the method is to be
highly recommended ; only care must be
taken that the stacking is well done,
starting with a good broad base and
gradually thinning. Otherwise, the first
bull that comes along and tries to get
at a dainty morsel growing inside,
knocks down half the fenceand makes
endless work.
PICKING,
I do not believe in picking by means
of a long bamboo witha knife attached,
as the trees do not get cleaned, and the
pickers are liable to cut down immature
bunches, which is undoubtedly a serious
loss. I persisted in the climbing process
which, although a little more expensive,
is I consider cheap and safe in the long
run. Iconsider nothing requires such
careful supervision as the getting of the
right bunches picked, as after all, the
labour and expenses on anestate is for
the purposes of getting the best fruits
at harvest.
15
PROPPING BUNCHES,
This I found absolutely necessary, as
certain young trees have long fruit
stalks, and these stalks being weak could
not support the weight of the bunches,
A little experience and _ observation
taught me that the propping requires
careful attention, forif itis not done
carefully and thoroughly more harm
than good would be the result. Luckily,
I had a large reserve jungle to procure
my props from, and so had the pick and
choice of the best sticks and was not
limited to number. My experience has
taught me that the props used should be
of the strongest willowy timber; that
the ends should be carefully pointed ;
that the props should not be longer than
is absolutely necessary for the particular
bunch and the situation of the bunch;
that the bunch should only be very
slightly raised; that the point of the
prop should be very securely driven into
the trunk of the tree, and that the
FORK OF THE PROP SHOULD BE INSERTED
INTO THE CENTRE OF THE BUNCH
and not at theend. The cutting, point-
ing and propping cost for 11,160 props
is Rs. 74°51, the work being done by
trained Tamil coolies under direct super-
vision. Trees from 20 to 25 years old
seemed to getover this propping stage.
I should think that in selecting nuts for
the nursery, if they were chosen from
trees that always.had short tough fruiz
stalks, we would be able to reproduce
‘chips of the old block” and propping
becomes a thing of the past. Propping
becomes a serious question on some
estates, as props of any kind are getting
scarcer and searcer, and prices higher
and the sources are getting less and
further away. It would be a great boon
to most planters if some inventive genius
would produce a suitably cheap, pliable,
imperishable substitute to the jungle
forked-stick now used, I read in an
English magazine that railway rails
were being manufactured out of com
pressed paper; if that is possible, it
should make excellent props with the
addition of a steel point.
DRYING.
It seems a great pity that no better
process has been introduced than the
present method of smoking, Thesystem
is scientifically incorrect and risky, but
I suppose, with the usual backwardness
of Ceylonese enterprise, it will be a long
time yet before we get anything better.
I had a great deal of experience in dry-
ing apricots, peaches, raisins, pears,
plums, ete., which wasentirely dried by
the suninaclimate where the average
rainfall is 14 in., and the thermometer
very often registered 120°in the shade.
The fruit was exposed to the sun on
Oils and Fatst
»Oils and Fats, 130
wooded trays after being subject to the
fumes of sulphur during the night.
Copra drying is much easier as the nut
is not so perishable and does not require
such careful handling as fruit. It is,
however, very important that the dry-
ing ground be large and open, so that the
copra gets the direct rays of the sun
‘during the greater part of the day. It
is impossible to turn out first-class copra
ona small faulty shady ground. Care
must be taken not to break even during
the best of sunny weather more nuts
than the drying shed would hold in case
of rain.
FAULTILY CONSTRUCTED DRYING SHEDS
are an abomination and a_ source
of great dissatisfaction. Well con-
structed drying sheds should be the first
consideration of a proprietor, as other-
wise badly dried copra is the unsatis-
factory result anda source of dissatis-
faction both to the proprietor and
superintendent, although unfortunately
the latter would more than likely get
the blame, although expected to make
‘bricks without straw.” As the saying
goes, that the ‘‘ proof of the pudding is
the eating of it,” this article would not
be complete without giving some idea
of the results of my work. I was able
in three years to reduce my labour staff
from sixty to forty all told, which
meant thirty actual labourers, the other
ten being watchers, carters, etc.
THE NET PROFIT
when I took charge was Rs. 9,000 per
annum, and four years afterwards it
amounted to Rs. 29,000 per annum,
after erecting some permanent build-
ings, planting 24 acres of new land, and
doing other permanent work such as
drainage, constructing bridges, and
making roads, ete.
In CONCLUSION
I consider that there are various pro-
blems to be solved in connection with this
(FEBRUARY, 1909,
industry, and as no individual proprietor
has either the time or money needed for
experimenting purposes, it should be
THE DUTY OF GOVERNMENT
as isdonein other countries, to carry
out expriments and show the people
the best methods; for instance, supposing
a land under coconuts was a clay loam,
what would be the result if the land was
yearly ploughed to a depth of 8 to
10 inches, and during the dry months if
the soil was constantly kept stirred up
by means of a set of disc harrows or
other cultivating machines? Expe-
rience has proved beyond question in
other countries that in planting this
process is absolutely necessary, as it bene-
fits the trees, thereby greatly increas-
ing the yield. But whether it would
benefit the coconut tree and make it
yield sufficiently to cover the increased
cost of cultivation as well as to give an
increased surplus, isa question that can
only be proved by experiment. Then
again ploughing is no doubt better and
would be cheaper than hand work if
only suitable ploughs with suitable
motive power could be procured. Un-
fortunately we have neither at present.
The ploughs in use at present with one
handle and a pole does a half ploughing
half scratching business to an uneven
depth of not more than 3 to 4 inches,
which is practically useless. These
ploughs are absolutely faulty in con-
struction, and I defy any ploughman to
do good work with them, leave alone the
ordinary estate cooly.
in fact the whole question evolves
down to this. Do‘*we get as much as
could be possibly got out of the coconut
palm, or would better modes of cultiva-
tion greatly increase the yields both in
quantity and quality ?

COTTON CULTIVATION IN THE
KURUNEGALA DISTRICT.
By Dr. H. M. FERNANDO, M.D.
Dr. Willis has stated that an experi-
ence extending over three years is neces-
sary to makea definite pronouncement
as to the results of cotton cultivation.
In this Paper I venture to embody the
experience gained in cultivating this
product inthe Kurunegala District for
five consecutive years.
START.
A commencement was made in 1903
ona very small scale with Upland
cotton, and the indigenous’ variety
known as Kidney cottor, which grows
so freely asa perennial in village gar-
dens. In 1904, with selected seed sent
by the Cotton Growing Association,
a definite series of experiments on a
larger scale was started with the
following varieties of cotton :—
(a) American Upland.
(6) Sea Island.
(c) Egyptian Mit-Afiffi.
(d) Kidney,
About ten acres were devoted to each
variety, and the resulting crops were
inned and baled by _ hand-machinery
forwarded to me by the Cotton Grow-
ing Association, to whom the cotton
was consigned for sale and report.
The results of the sale, although the
quantities were not sufficiently large
to attract proper competition amongst
buyers, were eminently satisfactroy.
The Upland and Sea Island varieties
fetched higher prices than the average
prices of the British cottons grown in
America, and the Egyptian cotton was
quite equal to the average samples pro-
duced in Egypt.
THE OBJECT OF THE 1905 EXPERIMENT
was to find out which of the varieties of
cotton fetching a ready sale in the mar-
ket of the world was best suited to
the district in which the experiment
was conducted.
It was also essential to determine the
proper season of the year tc commence
the planting.
_ The Upland variety reaches maturity
in the shortest time, requiring about
four and a half months only for the
crop. The Sea Island needs about five
months, whilst Egyptian cotton re-
quires about a month longer. In well-
drained land all the varieties demand
plenty of rain for growth and matur-
ation, and an assured period of dry
weather to follow to enable the crop
to be picked without damage.
YIELDs.
The Egyptian variety gives the
heaviest yield, and the Sea Island the
smallest. As the latter fetches the
highest prices it was found that it was
the most remunergtive to grow.
The distribution of rainfall and dry
weather obtaining in the district ren-
dered it absolutely necessary to plant
cotton with the North-east monsoon
rains in October and November, and
depend on the February-March drought
for the crop. These weather conditions
precluded the successful cultivation of
the Egyptian variety, Since 1905 only
Sea Island cotton was cultivated as an
annual crop.
The land at my disposal consisted
of either virgin forest, or chena, gener-
ally undulating. Owing to the nature
of the land, the number of stumps on
the ground, and the fact that cotton
formed a catch crop amongst rubber or
coconuts, the only attention the cotton
received after planting was clean weed-
ing. Efficient cultivation of the soil
which is essential to the proper growth
of cotton was not carried out. Even
under such adverse conditions of growth
the yield of lint per acre, which varied
from 11C to80 pounds in different years,
was satisfactory. This yield was ob-
tained over an area of about fifty acres
each year, and fetched prices varying
from 10d. to 1s. per pound.
PESTS: THEIR PREVENTION.
Every variety of cotton, grown in the
wet zone in Ceylon, is inclined to be-
come a perennial. This habit of the
plant must be systematically checked
if success in cotton cultivation isto be
secured. After thecropis gathered, the
plants should be rooted out, or allowed
to be eaten up by cattle or goats. The
necessity for this is due to the fact that
cotton is highly susceptible to insect
pests, and if it is grown asa perennial,
the indefinite multiplication of insects,
with a permanent food supply at their
disposal, will ultimately ruin the culti-
vation. Treating cotton as a six months
crop every year is the best means of
fighting its) insect enemies, In the
Kurunegala District at least two kinds
of insect pests were met with, The
Fibres.
eaterpillar which feeds on the leaves
is not a very serious menace. It can be
effectually and economically kept at
bay by theuse of the Paris-Green Spray,
consistently applied from the time it
makes its first appearance. On the
other hand, the insect which destroys
the bolls appears during the period
that the bolls are formed, and can only
be prevented from multiplying indefi-
nitely by preventing the cotton plant
from assuming a perennial character.
CorTrron SUCCESSFUL ROTATION CROP.
From the above considerations it will
be evident that cotton cultivation may
be carried on in Ceylon with profit if
planted in flat lands capable of easy cul-
tivation as an item in a series of crop
rotations. In districts where the rain-
fallis sufficient, and its distributions
favourable, the crop may be grown as
in America and in West Indies without
irrigation. Onthe other hand, where
irrigation water is available, the most
favourable conditions exist for the
carrying on of this cultivation—condi-
tions simillar to those that prevail in
Egypt. I have no hesitation in stating
that with proper cultivation and under
irrigation a crop of 250 to 300 pounds of
lint per acre may easily be gathered
with the Sea Island variety, and perhaps
490 pounds or more with the Egyptian
cotton, Such acrop at present prices
182
_ [Fervary, 1909.
would yield a very handsome profit and
one sufficient to attract capital to
remote and unopened districts, provid-
ed, however, labour is available.
JAFFNA A SUITABLE CENTRE,
In the Jaffna peninsula, on the other
hand, where labour is plentiful, and
where the sytem of farming is such that
cotton can easily represent an item of
ordinary cultivation, this product may
be grown with greater success than
perhapsin any other part of the Island,
Now that tobacco cultivation is no
longer profitable, I would suggest that
cotton be grown in place of tobacco.
Cotton requires less water and infinite-
ly less care and attention than tobacco,
whilst the present prices promise greater
profits. The surface-wells so prominent
in the Northern Peninsula are admir-
ably suited to the irrigation of cotton.
MARKET FOR COTTON.
Hitherto considerable difficulty exist-
ed in the sale of produce by small
farmers, as there were no local buyers
for the unginned produce. The pioneer-
ing work that has already been done
has encouraged the British Cotton Grow-
ing Association to set up a local ginning
plant through their agents in Colombo,
who are prepared to help all growers,
however small, to sell their produce at
the best market rates.

EDIBLE PRODUCTS.
COW-PEAS.
By Ligeut.-Cou. J. R. Y. GOLDSTEIN.
Departmental experience with cow-
peas has shown them to be a most pre-
carious crop under ordinary field condi-
tions. They are most sensitive to Jate
frosts, and even a cold day checks them
severely. As a commercial crop they
are not held in high estimation, although
for green manure or fodder they are of
great value. Under irrigation in the
Goldburn Valley excellent crops have
been grown.
Last season varieties were supplied to
Lieut.-Col. Goldstein, who
undertook to test them at the Chelten-
ham Convalescent Home for Men. Con-
‘sidering the nature of the soil and the
unwonted dryness of the season, the
results, as given in the following report,
are of value: —
It will be remembered that the winter
of 1907 was sodry that the subsoil was
deprived of its annual wetting, Conse-
quently, spring and summer growth was
unusually backward, and was further
injured by the absence of summer rains,
The cow-peas sown late suffered like
other vegetation, and there were many
gaps in the lines. But, being drought-
resistant, the bulk of them came
through the dry season satisfactorily.
The four varieties supplied were, New
Era, lron, Wonderful, and Whip-poor-
Will. The parcel of Iron contained peas
of two colours, though evidently true to
name ; these I separated and sowed in
distinct plots to test for ‘any difference,
naming them provisionally, ‘‘ White
Iron,” and ‘Red Iron.” The result
showed the dark to be a fortnight later
than the light pea, but the difference
may have been accidental and will be
tested further. All the peas were sown
on 18th October, and they ripened seed
in the following order :—

Red Iron ... 24th ,, ried Wiss Bea
Wonderful 28th ,, > D1OFe:
Whip-poor-
Will «. 19th; March, ,, 139. ,;
All continued to produce pods until
16th April, when they were ploughed
in by mistake, but previous experience
in Gippsland goes to show that cow-
peas will produce pods until stopped by
cold. The pods were gathered weekly
and careful records kept. The heaviest
gatherings were obtained during the
third and fourth weeks in March and
the first week in April.
White Iron and Red Iron are similar
in growth and yield, plants about 20
inches high, ripening seed early, and
bearing pods in succession for about
three months; pods about 7 inches long,
containing 12 to 16 seeds of medium size.
Imported seeds are deep brown in colour,
some being cream-coloured.
New Era, the second earliest, is a low-
growing, slender bush with delicate
foliage, small pods and seeds ; pods about
6 inches long, thin, containing 12 to 16
seeds, brown in colour and mottled.
Wonderful, third in order of ripening,
has robust and spreading growth, with
strong branches and large leaves, cover-
ing the ground quickly; plants about
14 inches high ; pods about 8 inches long,
thick, containing 12 to 18 medium-sized
peas, flattened at the ends, colour
reddish brown.
Whip-poor-Will, a late variety, is
strong in growth, withan abundance of
large foliage; branches spreading and
numerous; height about 18 inches; pods
about 9 inches long, fleshy, containing
2 to 18 large peas, kidney-shaped, brown
mottled.
A STRONG PLEA FOR THEIR CULTURE.
Cow-Pea plants grow vigorously until
they commence bearing, then slowly until
April, when they start a second growth,
throwing out branches with a running
habit, soon forming a densely-matted
mass of rich, succulent herbage suitable
for fodder, ensilage, or green manure,
The plants are specially suitable for
making into stack ensilage, which may
be done in the paddock where grown,
thus reducing labour, bringing ensilage-
making within the scope of any small
farmer, and thereby inducing that class
to adopt the making of ensilage regu-
larly. When ploughed under, for green
manure, the soft, sappy mass rots very
quickly, so that any other crop may be
sown almost immediately. It is this
quality, of speedily breaking up inthe
soil, due to the luxuriance of its second
growth, which constitutes much of
the value of cow-peas for manurial
purposes. It has been claimed for
this plant that, under favourable con-
ditions, two sowings can be grown
successively in one season, which further
heightens its value for restoring humus
to hungry and worn-out soils, It

also gives a heavy dressing of nitrogen
to the soil, which benefits the following
crop, and even when the plants have
been cut for fodder, the remainder, when
ploughed under, is much more useful
than the dry stubble of any other crop,
Cow-peas should be sown as early in
spring as possible, but where there is
anger from hard frosts, sowings may
be delayed until later. They will
flourish in all parts of Victoria, from the
Murray to the sea, and will succeed in
the poorest soils and the driest seasons.
In rich soils, they should be sown 2 feet
apartin the row, rows 3 feet apart. In
ordinary soils the plants may be closer
in the row, say 18 inches apart; and in
oor soils 12 inches in the row, and 30
inches between rows.
American farmers regard cow-peas
with much favour and grow them largely
for many uses, but green manure is the
main purpose. American cattle and
sheep Asian well upon the fodder, the
plant being rich in albuminoids and
carbohydrates. In the household, the
green puds are found to be equal to
French beans, while the dry peas are
used to replace haricot beans for table
use. Their long period of bearing—cow-
peas podding freely for three or four
months during the hottest summer—
should commend this plant to our
market-gardeners. For seed, cow-peas
are very profitable, yielding from 20 to
40 bushels per acre. The retail price
here, at present, is about 30s. per
bushel, while field peas are about 4s. 6d.,
with a similar yield of seed. This great
difference should give large profits to
growers of cow-peas for some consider-
able time. But, even were the price to
be reduced to that of ordinary peas, the
cow-pea would still be the more profit-
able crop to grow; its superiority being
manifest from its not drying up after
its seed has been ripened, and by the
value of the second crop of material for
fodder or for manure; material, perhaps,
of nearly equal money value to that
obtained for its previous crop of seed.
What greater inducements can Victorian
farmers require to make them give cow-
peas a trial ?
Although this plant is called a pea, the
seed isshaped like abean. Botanically,
it is closely allied to the Dolichos. It is
described under thename of Catiang
sinensis, synonym Vigna sinensis. It
has been in use for food purposes fora
thousand years or so; itis the Chowlee
of India, the Tow Cok of China, the
Caffre bean of the Cape, and now the
Cow-pea of the United States. There
are several varieties, with seeds varying
widely in shape and colour, white, grey,
brown, and black, with many inter-
134

mediate shades and markings. It is one
of those tropical plants, like maize,
which grow well in cool climates and
ripen their seeds freely.
I am not aware that any extended
attention has been directed by scientists
to changes of colour in seeds growing
under varying conditions, but the
changed colours under the present tests
are too remarkable to be passed over.
All peas pproduced from dark-brown and
from reddish seed have come white;
there is not onc dark seed in the produce
from either Iron or Wonderful. In New
Kra, the brown has disappeared, the
produce showing a rather pleasing shade
of grey ; Whip-poor-Will, a dark seed,
has produced’ buff-coloured peas. As
it is the red colour which has vanished,
the change may possibly be due to
the absence of iron from _ the soil.
Cheltenham soil is almost entirely
composed of a silicious sand containing
no iron; but, as most manures contain
some iron, the disappearance of red from
the colouring of all these peas seems to
me to indicate clearly the extreme
poverty of the particular soil in which
they were grown. It will be interesting
to experimeut this season with appli-
cations of iron sulphate in different
proportions, At any rate, present
results are so striking that they should
be worth placing on record, not only
because they show the impoverished
condition of the soil, but also because
they go to prove, incontestably, that
cow-peas can be depended upon to
produce fair crops in poverished and
poor sJils, even in very dry summers. I
propose to continue tests this year,
adding three other varieties, and sowing
a month earlier than last season.—

With the exception of lucerne, we are
unable in this climate to grow any per-
manent leguminous crop as a change of
feed for pigs.
In mixed farming the value of cover
crops in replacing the fallow is now
being generally conceded. It is neces-
sary to differentiate from those used as
catch crops and for green manuring.
Cover crops check evaporation, pre-
vent the soil baking, also the loss of
plant-food by excessive rainfall in wash-
ing the soil or leaching and they afford
green, succulent food for stock.
Plants belonging to two groups are
available for this purpose. The first are

those known as the legumes, which
possess the specific function of assimil-
ating or storing nitrogen in the soil.
They include clovers, cow-peas, Canada
field peas, vetches, soy beans, velvet
beans, lupins, and Beggar weed (Desmo-
tium tortuosum), The second group are
non-leguminous and embrace rye, wheat,
barley, oats, buck-wheat, rape and
mustard.
The cow-pea is looked upon as the most
useful. It forms asucculent, relishable,
nutritious forage for sheep, cattle, and
pigs during the hot summer months.
At that period all other palatable
fodders of high protein content are not
available and the natural grasses and
herbage are dry.
Cow-peas as a drought-resisting fodder
Stand unrivalled. They have been used
in India and other notoriously dry
countries for centuries. They have
acclimatised well here. The roots of
the plant, like that of lucerne, penetrate
deeply into the subsoils, in a vigorous
fashion searching for plant-food and
moisture, and at the same time opening
up the subsoils and rendering them
porous and available for the storage of
moisture and air. The roots attack the
stores of phosphoric acid and potash,
dissolving them for their own use as well
as for subsequent crops.
The characteristic nodules of legumes
are found freely distributed along the
roots, and in these the bacteria are
engaged in assimilating atmospheric
nitrogen and promoting nitrification ;
inert plant-food is made soluble and a
source of root nourishment.
The roots and stubble are ploughed
in with the excreta from the grazing
animal. Itis approximately estimated
that the former alone give to each acre
24 lb. nitrogen, mostly gathered from
the air, and return 6 1b. phosphoric acid
and 15 lb. potash, largely drawn from
the subsoil, and in a form readily assimil-
able by the next crop. The organic
matter provides humus and increases
the moisture-holding capacity of the
soil. Whilst the plant is growing the
thick rich spreading foliage covers the
ground, arrests evaporation, stops the
growth of weeds, and keeps the soil in a
loose friable condition.
It is anideal cleansing crop and pays
its way in furnishing stock fodder, and
in addition the soil is enriched with
humus, nitrogen, potash and phosphoric
acid, fertility is restored, and the land
effectively manured for a main crop. In
short, to use a familiar farmer's phrase,
the land is brought into ‘‘ good heart,”
Edible Products.
As a food for stock, particularly pigs,
during the latter part of summer we
have had abundant evidence of its flesh-
producing capacity, and, as with lucerne,
its power to provide a suitable inter-
mixture of lean flesh in bacon and pork.
Young pigs three months’ old, when
building up frame and tissue, make ex-
cellent progress on cow-peas balanced
with rye, wheat, barley, potatoes, or
maize. Theration can be modified to suit
the needs of the animal as it approaches
the fattening stages. The foliage of the
plant may be utilised for providing
green forage, or allowed to ripen suffi-
ciently for hay or silage, or the beans
can be used as pig-feed. As a fodder
the yield per acre varies, and is deter-
mined by the variety grown, soil, culti-
vation, and climate. At this College
quantity has ranged from 4 to 12 tons of
green feed per acre. The composition
will average as follows :—
Water 84 per cent,

Vari-
ation ranges between two distinet
classes, cne class being upright in
growth, compact, bushy in habit, and
without runners; the other producing
long, trailing vines, or runners, and
spreading well over the soil.
The first or bush varieties are noted
for their heavy, quick growth and suc.
culence. Amongst these the following
have proved most successful on this
farm—Poona and Chinese Mottled. In
hot dry districts, with a sparse rainfall
cow-peas take longer to mature. The
best sorts are thoseof trailing or recumb-
ent habit. They possess a deep root-
growth and are better enabled to with-
stand drought. The sorts recommended
are—Black, New Era, Clay, Whip-poor-
Will, and White. It should be remem-

bered that cow-peas readily alter their
habits in response to local conditions of
soil and moisture.
The seed-pods range in length from 4
to 16 inches. These, with the seeds,
are of all sorts, shapes, and colours.
Each sort varies in time of maturing,
habit of growth, ripening and other
features. It is best to select tested
varieties for the main crops and to con-
duct tests with new sorts on ‘a’ small
scale.
The most satisfactory variety subject-
ed toaseries of trials here for the past
six years is Poona, an upright, bushy
plant, of vigorous and dense growth.
This was. originally imported by the
late Mr. Farrer, from the Department
of Agriculture of India. We have had
a yield as high as ten tons to the acre
from it. Cow-peas revel in heat and sun-
light, and will thrive ona wide range
of soils; generally they do best on light
soils. The light sandy loams at this
College have always afforded good re-
turns from this plant. The only soil in
which it will not respond is that which
is constantly wet. In all cases the
soil should be deep, well drained and
mellow.
On impoverished soils the crop is one
of the safest and most certain renova-
tors. Being a hot-climate plant it is
necessarily very susceptible to frost, and
planting should not commence until
frosty weather has passed. November
is usually the month to sow the main
crop, although successful crops have
often been secured from October sow-
ings. Fresh sowings may be continued
until February. The soil must be well
cultivated and brought into a fine con-
dition of tilth. Where manure is re-
quired, the best stimulant to rich
growth can be secured from an appli-
cation of fertilizers affording phosphoric
acid and potash. This is supplied by the
following :--
Superphosvhate, 200 lb.; Muriate of
potash, 100 lb. per acre spread broadcast.
In some soils—clay loams—itis found
essential to release plant-food by dress-
ings of lime at the rate of half to one
ton per acre,
The hest practice is to sow the cow-
peas indrills 2 ft.6in. apart, the seed
6 to 8 inches from each other, and
covering with soil about 2 inches.
The use of a maize drill fitted with a
plate having ¢ inch holes facilitates
sowing.
Cow-peas germinate quickly on moist,
well-prepared soils. The whole crop
186
[FEBRUARY, 1909,
grows rapidly and evenly. Shallow cul-
tivation should be followed once a
month with secuffler or cultivator until
the plant is developed.
Of late years the practice of sowing
climbing varieties of cow-peas with
maize or sorghum has been adopted with
very goodreturns. The yield peracre, in
many instances, has been doubled. For
conservation as silage this class of crop
is becoming increasingly popular, especi-
ally the combination of maize with cow-
peas,-seeing the increase of protein by
ihe latter asissts to balance the food
constituents.
In using the crops for hay the best
time to cut is when the first pods beign
to ripen. Like Red clover it is liable to
heat if carted and stacked too early.
The cut hay should be left exposed to
the sun for a few hours, and then put
into cocks for thiity-six to forty-eight
hours.
Care should be observed in drying not
to allow the leaves to become brittle.
If the hay be too moist when stacking
it is likely to become mouldy. It should
be carefully stacked and protected from
the weather.

Soy oR SoJA BRAN.
This plant comes from Japan, and of
late years has attracted attention as an
annual leguminous plant which produces
the richest of all beans in protein and
fat. It closely resembles the cow-pea, is
of bush form, erect, hairy, branching
freely and growing to a height of 2 to
5 feet.
The seed pods are clustered on the
main stems and branches. are 1 to 2
inches long, and contain from 1 to 3
seeds or beans.
They give a greater yield of beans
than cow-peas. They are not trailing in
habit, hence are more easily harvested.
They mature early, but last lounger than
cow-peas, and afford alonger season for
pigs to feed on them. Hither the green
forage, hay, or beans should be associ-
ated with other foods owing to their
richness. In feeding the bean it should
not be more than one-fifth of the total
ration. As high as ten bushels of beans

to the acre have been harvested here.
These are classified as the richest of all
natural vegetable foods, and should be
used to strengthen the ration in protein.
With their aid pigs can then be fed
with potatoes, maize, barley, rye, or
other starchy foods. As a green forage
crop they are highly appreciated by
pigs, and afford a more nutritious diet
even than cowpeas. The plant can be
converted into hay in asimilar way to
that of cowpeas.
As silage it has been foand most suc-
cessful when mixed with twice its
weight of green maize.
The soy bean requires a good loamy
soil well drained, although like the cow-
pea it is adapted to a wide range of soils.
A deep, firm, well-tilled, moist seed-
bed is required here. It should be
ploughed to a good depth about the
end of July or beginning of August
and worked (harrowed and volled) to a
fine tilth. Should fertilisers be required,
use that recommended for cow-peas.
The seed should be sown when all
chances of frost are over;as a rule the
beginning of October is best when some
warmth is in the soil.
Sow in drills 2 ft. 6 in. to 3 ft. apart.
One plant should be permitted to grow
every Ginches. Krom 8 to 10 1b. of seed
per acre is needed. Shallow cultivation
should follow until the plants are well
grown, The quickly maturing plant
and pods ripen in from seventy-five to
ninety-five days. It is a good drought
resister.
As a food for pigs, either as beans,
green forage, or hay, it has a high repu-
tation. The animals fatten quickly, are
always thrifty, with strong appetites;
the hair and skin acquire a glossy look,
and the skin feels as if they were fed on
oil meals.

So far this leguminous plant has only
been grown in an experimental way to
test its capacity as a fodder, but suffi-
cient data. have been secured to war-
rant extended trials for its useas green
summer forage, for green manuring,
and as a cover crop.
Its leading drawback is that it requires
along summer for its proper develop-
ment, as it is a native of Incia and
thrives well in a hot, dry climate.
Both plant and bean are useful as
fodder tor stock, and pigs relish the
food and provide good returns onit. It

state and produces vinee running from
29 to 30 feet in length; they twine
around any obstacle, and are often
grown In conjunction with maize.
It is a heavy cropper and has been
known under favourable conditions to
produce thirty tons of green forage per
acre. The seed may be sown inthe warm
districts in October. The roots go well
down into the subsoil ard necessarily
require a deeply ploughed soil. The
seed should be sown in drills3 ft. 6 in.
apart with a space of one foot between
each. The best fertiliser is :—
Superphosphate . 150 lb. per acre.
Sulphate of Potash ... 80 ,, 6
Cultivation should be pursued as long
as the plant growth will permit. Owing
to the entanged nature of its growth
it is difficult to cut for stall green feed-
ing or hay. It is therefore best used as
a grazing crop, and the pigs should be
turned in to eat it off.—Agricultural

THE CO-OPERATIVE MARKETING
OF CITRUS FRUITS. -
THE CALIFORNIA E'RUIT-GROWERS’
EXCHANGE,
The Honourable the Minister for
Agriculture is in receipt of a letter from
Mr. A. Downe, a resident of Los Angeles,
California, who recently visited New
South Wales, and made a careful inspec-
tion of the citrus groves of the County of
Cumberland. Mr. Downe has an orchard
of some 24 acres at Duarte, California,
and can therefore speak as a fruit-
grower to fruit-growers. Mr. Downe
refers to the prevalence of fumigating
with cyanide in preference to spraying,
declaring that the latter process has
been abandoned, as it causes ‘‘die back”
of the fine twigs and sprouts.
The freight from California to New
York is 4s. 6d. per 100 lb. box a distance
of 3,000 miles.
Oranges are shipped east to New York
and London and throughout Canada,
and arrive in condition.
The new crop for next year promises
to be a heavy one, probably the heaviest
for years, due no doubt, Mr. Downe says,
to liberal fertilising and fumigating.
The marketing of the enormous crop
is as important as growing it, and
California fruit-growers have established
the California Fruit-Growers’ Exchange
to perform this work. As there is
nothing of this kind in existence in this
Fdible Products.
State, the need of such a corporation was
apparent to Mr. Downe; he _ has, there-
fore, been to no little trouble in collecting
information on the subject. From a
pamphlet issued by the California Fruit-
Growers’ Exchange, forwarded by Mr.
Downe, the following is taken :—
“Twenty-five years ago the annual
total shipments were scarcely twenty
carloads. Fifteen years ago the annual
shipments were approximately 4,000 car-
loads, or slightly in excess of a million
ee quarter boxes (a box holds 2 cubic
eet).
“Since that time there has been an
increase from year to year, until the
average of the last three seasons has
reached the vast volume of 30,000 car-
loads, or 11,000,000 boxes yearly. The
net f.o.b. value of the crop of 1906 has
been conservatively estimated at twenty
million dollars.
“When citrus fruit-growing in Cali-
fornia emerged from the stage of
experiment and past time into that of
profit-seeking, the problem of marketing
immediately confronted the growers.
They were thousands of miles from the
populous centres in which their fruit
must find consumers, and they had
practically no home markets nor agencies
through which they could convert it
into ready money at remunerative
figures. It is true there were speculators
in the field, but their offers to buy were
at very low prices, and only spasmodic
at best. This is not strange as the
speculators were but go-betweens, and
the markets being undeveloped they
could only offer for the most part to
take the fruit on consignment for
grower’s account. If passing the specu-
lator by, the grower sought relief by
consigning his produce to the market
himself, he was little, if any, the gainer.
These were the conditions in the early
nineties, when the citrus fruits of
California orchards were less than one-
tenth the present value.
«““Various expedients were resorted to
for the betterment of these conditions.
Speculators attempted to form a compact
to apportion among themselves the
territory where the fruit was grown, to
fix maximum prices to be paid for fruit,
and also to establish f.o.b. prices, regular
credits and equalise distribution in
consuming markets. Growers’ and
speculators together sought to regulate
prices, consignments, and other im-
portant questions. The most disastrous
year so far as net returns were concerned
that the citrus fruit industry in this
State has ever experienced was 1892-3,
In Riverside and all other sections, where
there was any quantity of fruit to ship
138
at the time, account sales in ‘red ink”
were received without number. Inmany -
instances growers not only furnished
their entire crops for nothing, but were
also required to pay freight and packing
charges, which the gross sale of their
fruit did not cover. All of these efforts
to improve marketing conditions were
inadequate and short-lived. In the very
nature of things they could not be more
than partially successful, since the in-
terests of growers and speculators are
necessarily divergent on important
points. In several localities a few
growers had associated themselves to
secure better packing facilities, and for
mutual protection. In some instances
these associations had marketed on a
mutual basis.
“As a result of the above-mentioned .
failure of speculative shifters to sell the
year’s crop at fair prices, and particular-
ly stimulated by the association ex-
periences, large percentage of growers
sought to solve the vexed problem by an
enlargement of the association idea.”
“A Convention of Growers assembled
at the Chamber of Commerce, Los
Angeles, on the 4th April, 1903, the
declared purpose of the meeting being:
“To provide for marketing of all
the citrus fruit at the lowest possible
cost under uniform methods, and in a
manner to secure to each grower a
certain marketing of his fruit and the
full average price to be obtained in the
market for the entire season.”
“Following the recommendations of
this Convention of Growers, organisation
of associations and district exchanges
was effected in all the principal citrus
fruit districts, the packing to be done by
the association at cost, and the marketing
through an executive committee, com-
posed of one member from each district.
This arrangement for the marketing of
the fruit continued during two seasons,
viz., those of 1893-4 and 1894-5, but not
being entirely satisfactory, on October
21st, 1895, the Southern California Fruit
Exchange was organised, since which
date the marketing of the fruit controll- |
ed by the various district exchanges and
their associations has been conclusively
in the hands of the Southern California
Fruit Exchange, and its successor, the
California Fruit Growers’ Exchange,
except during the period of seventeen
months, from April Ist, 1903, to August
8lst, 1904, during which time the
Exchange interests combined in the sale
of their fruit with the principal non-
Exchange shipping interests under the
name of the California Fruit Agency.
The net results obtained during the
Agency period were not satisfactory to

the growers, and on September Ist, 1904,
the Exchange resumed the sale of the
fruit it controlled, independently of any
other factor.
“On resuming itsmarketing operations;
the Exchange passed the following re-
solution as a basis on which to operate :—
‘On May 20th we issued acircular,
advising all growers of the dissolution
of the California Fruit Agency, to take
effect September Ist next.
‘Upon the formation of the California
Fruit Agency, every effort was made to
sell the fruit f.o.b, California. All
agents were instructed to push this
policy, and imen were employed as
salesmen in the Sales Department of
the Agency who possessed ability and
much experience in that line, and who
have been in the employ of the leading
packers, as their salesmen for many
years.
‘Immediately after the California Fruit
Agency was organized, April Ist, 1903,
f,o.b. orders for fruit (usual terms of
inspection, ete.) were only received in
limited numbers, and not sufficient to
move a reasonable percentage of the
crop—although climatic conditions in
California were most iavourable to
restrict shipments. It soon became
necessary, in order to move the crop, to
ship, and attempt to make sales in
transit, or sell the fruit delivered at
market value at the point and time of
delivery.
‘Our crops are now so large that all
markets should be constantly supplied
with their full quota of fruit in order to
consume the output. This distribution
can be better accomplished by those
most directly interested,—the growers
themselves. The citrus-fruit-grower is
no longer independent of his neighbour
as to marketing his crop, but each one
is dependent upon the other, especially
in sofar as systematic distribution is
concerned.
‘The Southern California Fruit Hx-
change is composed only of growers
who recogniseall legitimate dealers in
the trade, and who are organised for
the purpose of disposing of their pro-
ducts in all markets of the country
upon the most advantageous terms, and
to secure distribution to the trade at
the least expense compatible with the
best service, securing to the consumer
the fruit at reasonable prices, and to the
grower the best average returns,

‘Growers or Associations of growers
not connected with the Southern Califor-
nia Fruit Exchange have the opportu-
nity now to associate or to form new
associations according to their pre-
ference, ro add to conditions existing in
their localities.
‘Believing that in co-operation with
each other, the best net results to the
growers can be obtained, we appeal to all
present Hxchange members and others
interested in maintaining values of
orchard property to put forth every
effort to secure as large a membership
as possiblein our associations and ex-
changes.’
“On March 27, 1905, the California
Fruit Growers’ Exchange was_ incor-
porated, and on September Ist following
succeeded to the business of the Southern
California Fruit Exchange. This change
in name was deemed advisable in
order that the market organisation of
itself might in name, as well as in fact,
become general throughout the State
rather than remain local to Southern
California.
“The Exchange was founded upon the
theory that every member was entitled
to furnish his pro rata of the fruit for
shipment through his association, and
every association to its pro rata of the
various markets of the country. This
theory reduced to practice gives every
grower his fair share, and the average
price of all markets throughout the
season.
‘Another cardinal provision of the
plan was that all fruit should be mar-
keted on a level basis of actual cost,
with all books and accounts open for
inspection at the pleasure of the mem-
bers. These broad principles of full co-
operation constitute the basis of the
Exchange movement.
“The Hxchange system
} : is simple,
but quite democratic,
The local associ-
Edible Products.
ation consists of a number of growers
contiguously situtated, who unite them-
selves for the purpose of preparing their
fruit for market on a co-operative basis.
They establish their own brands, make
such rules as they may agree upon for
grading, packing, and pooling their
fruit. Usually these associations own
thoroughly equipped packing-houses.
“All members are givena like pri-
vilege to pick and deliver fruit to the
packing-house. where it is weighed in
and properly receipted for. lHvery
growet’s fruit is separated into different
grades, according to quality, and usually
thereafter it goes into the common pool,
and in due course takes its percentage
of the returns according to grade.
“Any given brand is the exclusive
property of the Association using it,
and the fruit under this brand is always
packed in the same locality, and there-
fore of uniform quality. This is of great
advantage in marketing, asthe trade
soon learns that the pack is reliable.
“There are more than eighty associ-
ations covering every citrus fruit district
in California, and packing nearly two
hundred reliable and guaranteed brands
of oranges and lemons.
‘““The several associations in a locality
unite to form the local Exchange, which
serves aS a medium, and to a certain
extent as a buffer between the associ-
ations and the general Exchange.
“The California Fruit-Growers’ Ex-
change, referred to above as the General
Exchange, consists of thirteen stock-
holders, all directors, and all selected
by the local Exchanges. In other words,
the severa] local Exchanges designate
one man each from their membership as.
their representative, and he is elected a
director of the California Fruit Growers’
Exchange. By this method the policy-
making and governing power of the
organisation remains in the hands of
the local Exchanges.
“From top to bottom the organisa-
tion is planned, dominated, and in
general detail controlled absolutely by
the fruit-growers, and for the common
good of all members. No corporation
or individual reaps from it either
dividends or private gain.
‘““Sofar we have dealt almost exclu-
sively with the organisation of the Kx-
change, its co-operative aspects, and
general policy at home. Equally impor-
tant is its organisation in the markets.
‘“‘ Seeking to free itself from the shift-
ing influences of speculative trading,
by taking the business out of the hands
of middlemen at home, the Exchange
found it quite as important to maintain
the control of its own affairs in the
140
[KEBRUARY, 1909,
markets, It never contemplated the
opening of either retail or jobbing
houses, but to put the fruit into the
hands of the legitimate dealers first
hand. For this purpose the Exchange
established a system of exclusive
agencies in all the principal cities of the
country, employing. as agents active,
capable young men of experience in the
fruit business. Most of these agents are
salaried, and have no other business of
any kind to engage their attention, and
none of the Exchange representatives
handle any other citrus fruits. These
agents sell to smaller cities contiguous
to their headquarters, cr in the territory
covered by their districts.
“Over all these agencies are two
general or travelling agents, with
authority to supervise and check up the
various offices, These general agents
maintain in their offices at Chicago and
Omaha a complete bureau of informa-
tion, through which all agents receive
every day detailed information as to
sales of Exchange fruit in other markets
the previous day. Possessing this data
the sellingagent cannot be taken advant-
age of as to prices. If any agent finds
his market sluggish and is unable to sell
at the average prices prevailing else-
where, he promptly -advices the head
office in Los Angeles, and sufficient fruit .
is diverted from his market to relieve
it and restore prices to normal level.
In actual practice approximately 40 per
cent. of all the fruits shipped by the
Exchange is sold by public auction at
point of consumption, and of the remain-
ing 60 per cent. the greater part is sold
at private sale at a price agreed upon
between the seller and purchaser at
point of arrival on market conditions
as they prevail at that time. Through
these agencies of its own the Exchange
is able to get and transmit to its
members the most trustworthy informa-
tion regarding market conditions, visible
supplies, &c. This system affords a
maximum of good service at a minimum
cost. The volume of the business is so
large that ‘a most thorough equipment is
maintained at a much less cost to growers
than any other selling agency can offer.
“During the fourteen years of co-
operation in the marketing of citrus
fruits under the Exchange system, the
output of the State has increased from
4,100 cars in 1892-3 to 31,791 cars (including
Northern California shipments) during
the season of 1904-5, with a prospect of a
still further increase in the volume of
shipments in the very near future.
‘‘Marketing the fruit for its growers
at actual cost, the Exchange has been
able to bring about a great reduction in
packing and selling charges, with the

‘This co-operative movement is no
longer an experiment, organised upon
lines materially differing from any other
co-operative organisation; all the details
had to be worked out with extreme care
and caution. To have failed would have
been to utterly demoralise the citrus
fruitindnstry, as there were no adequate
marketing facilities. Serious blunders
in the execution of the plan would have
been almost equally disastrous. Natur-
ally this Growers’ organisation has met
with very strenuous and, in some in-
stances, bitter opposition from the
speculative elementsin the fruit trade.

EXPERIMENTS AT BOTANIC STATION.
The experiments conducted by Mr.
Joseph Jones at the Botanic Station,
Dominica, have been carried on for a
number of years on uniform lines and
furnish information of considerable
value. They consist of five plots, each
of approximately quarter acre, which
since 1900 have annually been manured
as follows :—

The results clearly show the value of
manures for cacao. During five years,
the use of phosphate and potash has
increased the yield of dry cacao 219 lb.
per acre per annum over the yield of the
plot receiving no manure. Similarly,
the use of dried blood, primarily a nitro-
genous manure, has increased the yield
by 187 1b., while the combination of the
142
[FEBRUARY, 1909.
two sets of manure (t.e., phosphate,
potash and dried blood) has increased
the yield by 374 lb. The mulching has
shown the greatest gain, namely 402 lb.
per acre per annnim.
By putting the moderate valuation of
6d. per lb. on cured cacao, a figure much
below market value, we may obtain an
idea of the monetary aspect of the case :—

The last two tables should be studied
together.
The mere consideration of the yield of
cacao does not fully explain the condition
of the plots and the changes taking
place thereon.
When the general health and growth
of the trees on the plots are taken into
account, itis at once seen that the in-
dividual trees on the mulched plot are
much finer and are better developed
than those on the other plots; the soil
also is better than thatof any other
plot. It is moist, friable, and full of
humus, and in a_ better condition
generally, which would appear to ensure
good crops for some time tocome. It is
also significant that this plot is well
covered by trees planted at the rate of
108 per acre, while the plot receiving no
manure requires 178 trees per acre, or
nearly 70 per cent. more,
Nextin general health and condition
may be placed plot 4, which received
phosphate, potash, and dried blood.
This plot requires at the rate of 124
trees per acre to coverit. The number
of trees on the other plots is as follows:
Plot 38, 1389 trees per acre; plot 2, 155
trees per acre; and plot 1, 178 trees per
acre. "
As the general rule of these experi-
ments, planters are recommended to
manure their cacao trees.
- Fepruary, 1909.
Organic manures such as pen manure
and liberal mulchings are doubtless the
best and most remunerative. Where
these cannot be obtained in sufficient
quantity, it is essential to give manures
containing nitrogen and phosphate, and
in many cases it willbe well to supple-
ment mulching with moderate applica-
- tions of nitrogen and phosphate.
Phosphate may be given with advantage
in the form of basic phosphate in appli-
eations of from 1to4 ewt. per acre. A
sufficient application in most cases will
be lewt-. peracre annually for several
years.
Nitrogen may be given in the form of
sulphate of ammonia at the rate of from
1 to 2 ewt. per acre, but nitrogen should
be given preferably in aform in which
it is more slowly available, suchas dried
blood, at the rate of 2 to 4 ewt. per acre.
With the development of the cotton
industry in these islands considerable
quantities of cotton-seed meal may be
within reach, This forms avery useful
source of nitrogen, and may be used at
the rate of from 3 to 6 ewt. per acre. It
introduces fair quantities of phosphate
and potash as well as nitrogen.
The present experiments afford uo_
evidence as to the value of potash and
phosphate independently of each other.
- The soils of Dominica are, however,
fairly well supplied with potash, and it
is not likely that this constituent is
urgently wanted. In the event of
planters desiring to experiment with
potash, it is believed that small dressings

GOVERNMENT PLOT AT PICARD.
This plot was started in 1900, in order
to ascertain whether cacao could be
grown on thelow lands at Picard. At
the time the plot was laid out, the
general opinion was that this district
was not suitable for cacao. Largely as
the result of the success of these experi-
ments considerable areas of cacao have
been planted in the neighbourhood, and
the success attending the newly-estab-
lished fields justifies the action. This
area is now regarded as one of the most
promising districts in Dominica.
The plot consists of one acre divided
into four sections. In the early stages
the whole of the plot was manured with
pen manure and dried blood. Iu 1903
the area was divided into four plots,
each of } acre as follows :—
A. Receving pen manure.
B. Receiving 2 ewbt. per acre of sulph-
ate of ammonia.
C. Receiving 4 cwt. per acre of basic
phosphate.
D. Receiving 4 cwt. per acre of dried
blood,
These manures are applied annually.
The southern part of plot D. is found
to rest on a gravelly subtratum; pro-
bably the old river bed extended to this
point. From 1905 this poor portion has
been dressed with pen manure in an
attempt to restore fertility,

The trees receiving pen manure have a’
very fine and healthy appearance, and
they have given the largest yield of
cacao.
The trees receiving sulphate of ammo-
nia also present a very fine healthy
appearance, but they have not yet come
into such heavy bearing as the trees
receiving either pen manure or basic
phosphate.
The plot receiving basic phosphate
has given alargereturn, and the trees
looking excellent condition. The foliage
is perhaps not so heavy asin the plots
receving pen manure or ammonia. The
plot experienced no lack of nitrogen, as
it has received a large number of green
deessings from the careful manage-
ment of the weeds which have grown
upon it and have been turned in. The
plot does not show indications of fall-
lng off such as are referred toin con-
nexion with the basic phosphate plot
in the large series of experiments at
Picard. It must, however, be remem-
bed that this plot, with the others,
Edible Products.
received good dressings of pen manure
and dried blood in the first two years
of its existence.
The dried blood plot, as explained
above, is rather uneven, but there are
some good trees upon it.
These four plots have been carefully
worked on the system which involves the
careful use of weeds as green dressings.
The growth of the weeds has been
watched, and assoon as they reached a
moderate size they are cut down and
either spread as a mulch or forked in.
(See ‘Manurial Value of Weeds in Cacao
and Lime Orchards, West Indian
Bulletin, Vol. V., p. 287).
The results obtained on these plots,
and the excellent condition of the soil,
would appear to show that while pen
manure when available is most valu-
able in cacao orchards, still the condi-
tion of the soil can be maintained and
improved by judicious green dressing
with weeds. The experiments should
be continued for some years, for it
will be interesting to see if the ferti-
lity of plots B. and C., receiving part
of manures with ammonia and phos-
phate respectively, will be maintained
without any other application.
LARGER MANURIAL EXPERIMENTS
AT PICARD.
The experiments conducted in co-oper-
ation with Mr. Sowray, the representa-
tive of Messrs. Rowntree & Co., have
given interesting results. These consist
144
[FEBRUARY, 1009, —
of twelve plots. Each plot, which is +
acre in extent, contains sixty-four trees
and is separated from its neighbour
by two rows of cacao trees. Plots 3 and
6 are separated from 7 and 10 by
three rows.
Measured by the number of pods pro-
duced, the results show in an unmistak-
able manner that manures are beneficial
and remunerative in the establishment of
young cacao. Judged on this basis, it is
seen that pen manure has given the best
results, the yield of pods of this season
from this plot being two and a half
times that of the plot without manure.
Dried blood has resulted in large
returns and so has bone meal.
Each of the constituents of manures
(phosphate, potash, and nitrogen, (as
ammonia) has increased the number of
pods ina marked degree, and this has
been the case whether these constituents
have been used singly or grouped in
various ways.
Plot8, receiving potash only, has given
an abnormally high yield and must be
disregarded for the moment,
Plot 2 shows a considerable increase of
crop as the result of the use of basic
phosphate; plot 6 shows that the crop is
only slightly increased by the addition
of potash, while plot 4 shows that the
addition of ammonia considerably in-
creases the yield.
For easy comparison the results may
be arranged as follows :—

‘plot has given a very large return, These
facts go to prove that nitrogen and phos-
phate are the constituents most required,
while the effect of potash is doubtful.
The best returns of all are obtained
from the use of pen manure which
contains nitrogen, phosphate, and _ po-
tash, and in addition large quantities of
organic matter. This latter substance
greatly improves the texture of the soil
and so adds very materially to its
fertility. Dried blood has also given
good results. This manure contains
nitrogen, phosphate and potash with
organic matter. The general results
with compost plot 9, have not been
satisfactory ; either the compost has
not been sufficient, or it is unexpectedly
slow in its action.
(1) Very vigorous, with fin
healthy foliage and
robust trees,
(2) Good, with healthy foli-
age and robust trees.
(8) Fair
(4) Lacking vigorous
growth, foliage poor.
Judged by theappearance of the trees,
we get a great deal of light thrown on
the effect of manures. The best results,
taking both the vigour of the trees and
the yield of cacao into account, have
been given by the use of pen manure.
The yield is the highest of all the plots
‘and the trees are the most vigorous.
Next to this we must place the bone
meal and the dried blood plots. Both
these manures convey to the soil nitrogen
and phosphate. Following these come
plot 10, ammonia; and plot 5, ammonia
and potash; and then plot 4, with
ammonia and phosphate; and plot 11,
with ammonia, phosphate, and potash.
After these, we come to a group where
the trees obviously lack vigour, and
where we may soon look for a decided
falling off. The striking feature in this
group is that none of the plots have
received any nitrogenous manure. It is
tu be noted that this group includes plot
2, phosphate ; plot 3, potash ; and_ plot 6,
phosphate and_ potash, all of which
have given good numbers of pods, and
which, judged from the crop returns
alone, would be regarded as satisfactory.
They cannot he regarded as satis-
factory, however, and a falling off in
crop is anticipated. The group includes
plot 9, compost; and plot 12, no-manure.

Estimating the effect of manures on
young cacao trees by taking account
only of the yield of cacao is likely to
be fallacious for more than one reason.
In the early stages there is likely to be
irregularity in the manner in which
young trees come into bearing, while
some manures may tend to foree the
trees into early bearing and lead to
early exhaustion. It is therefore neces-
sary to add to the statement of the yield
of cacao, observations as to the general
condition of the trees. When this is
done in connexion with these experi-
ments we alrive at very interesting re-
sults.
The plots may be roughly grouped
according to jthe health and vigorous
appearance of the trees :—
Pen manure

Plot 8. Dried blood.
Plot 1, Bone meal.
Plot 10. Ammonia.
Plot 5. Ammonia and potash.

J Plot 11. Ammonia, phosphate,
and potash.
Plot 9. Compost
Plot 2. Phosphate
rPlot 3. Potash
| Plot 6. Phosphate and potash
J Plot 12. No manure.
The lessons from these experiments
already begin to be valuable and may
be summarized thus :—
Manures are useful in establishing
cacao fields. Pen manure, when obtain-
able, is likely to give the best results.
Efforts should be made to increase
the humus in the soil as much as
possible, Manures_ supplying organic
matter are desirable as they tend to
maintain the supply of humus. Nitro-
genous manures are essential ; without
nitrogen the trees lack vigour. Phos-
phatic manures increase the crops, but
should not be used without nitrogen.
It would probably be good policy to use
nitrogenous and phosphatic manures
together. The effect of potash is not
very clear. It is probably notat present
urgently required as a manure.
It is recognized that some of the plots
are not likely to improve under the
manurial treatment they are receiving,
but their retrograde movement, should
it occur, will throw valuable light on
important points bearing on the manur-
ing of cacao. This will entail some loss
upon owners, butit is hoped this pros-
pective loss may be faced for the sake
of the valuable information likely to be
obtained.

PACKING AND SHIPPING
OF FRUITS.
THe AVOCADO.
First, we will consider the avocado,
which has always been considered a
difficult fruit to ship. Ido not consider
it such. I consider that the avocado is
a comparatively easy fruit to ship if it
is handled in the proper way.
The picking of the fruit should be
done within as short a time as possible
previous to the sailing of the steamer.
The avocado begins to soften very
rapidly after itis picked, and as soon
as that softening process begins, your
troubles begin. Youcannot then arrest
successfully the maturing process and
preserve the fruit. You should get
it into cold storage as rapidly as
possible after picking, and I would say
that under our present facilities it is
not quite safe to pick the fruit and
place it in cold storage and then take
it out to putit in the steamer, because
the refrigerating compartment of the
steamer, where you put your fruit in,
has to be kept opea for the reception of
other fruit, and your fruit which has
become chilled then becomes warmed
again and then chilled, and these rapid
changes in temperature are greatly con-
ducive to the deterioration of the fruit.
The fruit should be cut with great care
so as to avoid bruising. Perhaps it
seems superfluous to say this, yet I have
seen people who are in the fruit business
handling avocados in a way in which
a good down-east farmer would not
treat his potatoes; I have seen them
packed in boxesand specimens dropped
from this height (indicating about 34 to
4 feet) on to a concrete pavement floor
and then picked up and put in the
boxes as first-class merchantable avo-
eados. That won’t do. They must be
handled with extreme care to avoid all
bruising. The stems should be cut, as
IT have told you should be done in the
ease of oranges and lemons. Cut the
stem comparatively near to the fruit
and don’t put in leaves—do not cut the
stems long soas to include the leaves;
about a quarter of aninch oran eighth
of an inch is sufficient, that is, beyond
the natural joint. The packing should
be done also with care. [ have brought
here a fewcrates to illustrate the dif-
ferent possible packages, This crate (in-
dicating) holds approximately twenty-
four avocados. There isa smaller crate
which we have used which holds a
dozen. It is exactly the same as half
of this. This crate is more useful in
sending smaller shipments that are going
for private orders, In this crate you
will see that the fruits are only one tier
147
Edible Products.
deep. All fruit should be wrapped with
rather thin and yet strong paper. They
should be placed so as to pack snugly.
Tf you will recall the shape of the
average avocado you will notice that it
can be adjusted to a box of this size,
even though it be a little smaller in dia-
meter or alittle larger. The adjustment
can be done by means of tilting. If the
avocado is long you can place it like
that (indicating) if it is wide, it can be
tilted a little lowerand the next one be
put this way (indicating); if this is point
up, the next one can be point down, and
you can tilt it just as muchas is neces-
sary, the only requisite of the box being
that it must be high enough to receive
the avocado if it is lying directly on its
side. These boxes we fourd were not
quite large enough to receive the largest
avocados. I would say, do not put any
paper between the fruits. I found in
San Francisco that many of our shippers
from here were sending the fruits up
there in orange crates and larger boxes
than that and packing paper, wads of
paper, in between the fruts. Doubtless
the idea was to keep the fruit from bruis-
ing, but what is the result? You have
a solid mass of fruit and paper packed
closely together; the circulation of air
is rendered impossible, and it is about
like trying to refrigerate a wad of
cotton—you can’t get the refrigeration
into it; rather you can’t get the heat
out of it, you do not get the circulation
of the air, the cold air, about the fruit.
And there is no need of this paper if the
fruit is carefully placed so as to be snug.
Do not put in any leaves, The shipping
must be in refrigeration only. When
we first commenced shipping, people
told us that we could not ship in
refrigeration without the fruit all turn-
ing black. That depends upon the
refrigeration. But ventilation is out of
the question, ventilation without refri-
geration is out of the question—the
fruit will all arrive in the market
in a condition too soft to be received
by the wholesale trade. A great deal
of it may arrive there in suitable con-
dition for eating, but the trade will not
take it in thatform. The avocado will
endure retrigeration for a term of
three weeks any way. The exact time
we have not determined, but we have
determined that it will not endure
refrigeration as long as most temperate
zone fruits. The first deteriorating
effect of refrigeration is observable in
the darkening of the flesh close to the
seed, and then the flesh begins to turn
rancid; but it is perfectly safe to send
them as faras San Francisco or as far
as New York, so far as the time ele-
ment is concerned, The temperatures

that are best adapted for the refri-
geration of avocados has not been deter-
mined. We have carried them as low
as between 40 and 45 and as high as 50.
Fifty degrees I am satisfied is too high.
Our next hope is to try them between
45 and 50, and I think that somewhere
in there we will find the optimum tem-
perature. The temperature must be con-
stant, for variations intemperture, as I
have said, are deleterious to all fruits.
HANDLING THE FRUIT IN THE MARKET.
It is necessary when the fruit arrives
in the market, if there is not asale for
it immediately, that it should be stored
in refrigeration. If it is exposed, even
in San Francisco where it is cool, the
ripening process begins, and, as I have
said before, once they get well
under way it is difficult to arrest them
and preserve the fruit. Itis necessary,
therefore. for the fruit to go into cold
storage if there is not immediate sale
for it. As tothe market demands for
avocadys in San Francisco: As _ to
colour they prefer a green avocado.
I don’t know why, and I don’t think
they do, but they have been getting
green avocados from Tahiti, and _ pos-
sibly that may be the reason; but thatis
their preference at present. In other
parts of the United States, well, from
Pitsburg west they have no perference.
because they scarcely know the avocado
—it is an unknown article—butin San
Francisco it isa known fruit and that
is what they are calling for—green fruit
—although they will take the red or
the brown. I think that that is a
matter, however, in which a change
could easily be brought about, provid-
ed our best avocados should turn out
to be the brown or the red. Some of
our best varieties may be these. The
market demands that the fruit be
firm asI have already told you, You
cannot put fruit beginning to soften on
the market. In the first place, it is a
high-priced fruit, and the buyers who
handle the fruit, will not take the risk
of buying fruit, at a high price which, if
it is not sold within a day or two is
going to be a dead loss; but if the
fruit is firm, it will sell and sell at a
good price.
We should be careful, in
avocados, to send only those

a discussion of that question until we
come to a later part of the evening when
we are talking of the marketing of other
fruits since the problem is the same,
Tot MANGO.
The marketing of: the mango is about
the same as that of the avocado with
the following exceptions:—The crates
while they must be small, need not be
so smallas in the case of the avocado.
Two or three layers will be endured
a great deal better in the case of the
mango than in the case of the avocado,
but you must be careful not to pack
them in large packages. The refri-
geration can be more prolonged in the
case of the mango thanin the ease of
the avocados. The mango can_be kept
for at least six weeks safely. The mar-
ket demands for mangoes are nil. There
are no:demands. In San _ Francisco
where the fruit comes in spasmodically
from Tahiti and from Mexico, the sale
is a fairly ready one, rather slow, but
the supply is not constant; and, the sup-
ply being inconstant. there is no con-
stant demand, for that isa principle in
fruit marketing ; a constant demand pre-
supposes a constant supply. The mango
weevil is perhaps, our greatest enemy
at the present time, our greatest obsta-
cle in the way of a mango _ shipping
industry. We have the mangoes,
we have the varieties, and we know we
can grow them. We know also that
such fruit can be sold, though there is
no market now or a very limited one,
but a market for such fruit as the mango
can be created. But the mango weevil
is present here as you know. The
larvee hatches in the egg in the seed, and
because it is in the seed you cannot
examine the exterior of the fruit and
know whether you have the mango
weevil or not, and hence the inspectors
on the mainland feel that it is a very
important thing that they should see
that the mango weevil does not get into
California and thence into the whole
United States. It is not yet determined
whether the mango weevil will affect
other fruits than mango ornot. I be-
lieve the entomologists tell us that it
has not been reported upon any other
fruit or plant than the mango. Yet
eareful men wish to avoid all chances,
and we will have to expect that our
fruits will be carefully examined when
they reach San Francisco, and if they
are infested with the weevil they will
be turned down.
THE PAPAIA.
The picking of the papaia for the San
Francisco or for any shipping market
should be done when the faintest things
of yellow appear. As in the case of the
Feprvuary, 1909.1
avocado, it should be picked as_ nearly
as possible to the time of the sailing of
the ship. In picking the papaia the
stem should be cut about an inch or an
inch and a half long. Here there is
opportunity for some latitude, as the
length of the stem may be varied
slightly to facilitate the packing of the
fruit. This crate (indicating) is adapted
to the packing of the smaller papaias
of the long type. If the papaia does not
just fit here in its length, you can make
some slight differences in the cutting,
cut the stem half an inch longer or half
an ineh shorter and this crate accommo-
dates them. The papaia should be hand-
led with carealso. The wrapping should
be done with rather heavy paper and it
is preferable to have it glazed, because
if any fruit begins to decay or to get
soft, an unglazed paper will allow the
moisture to pass through to the adjoin-
ing fruit more quickly than the glazed
paper will. The shipping must of neces-
sity be in refrigeration. Ventilation
alone is again out of the question in the
case of the papaia, and extreme care
is necessary on the part of the steam-
ship agents and everybody who handles
the fruit to see that it is not bruised.
Picking upacrate of fruit and letting
it drop an inch or an inch and a half
jars the fruit and bruisesit, The papaia
is unknown in the markets, butit isa
taste which is rapidly acquired, as you
know, by almost everybody. lEvery-
body who comes to the islands either
enjoys the fruit at first contact or very
rapidly acquires the taste; and I believe
that a good market for papaias could be
worked up, particularly during the
season when the cantaloupes cannot be
found in the market.
THE BANANA.
The banana should be cut before it
becomes too ‘‘full,” as the term is used.
You will recall that a banana when itis
immature has ridges—corners—on it.
When it becomes fully mature and.the
fruit begins to turn yellow, those ridges
on the Chinese variety and also on the
Blue-fields or Jamaica variety
appear. When the fruit has become
fully rounded it is too far advanced for
shipping. Nobody can describe the
stage of maturity at which itis best to
cut the fruit—that has to be determined
by experience. The fruit must be cut
while it still retains the ridges, but the
degree of maturity will depend upon the
distance to market. The wrapper.—
Grass has been used as a wrapper.
Banana leaves are more commonly used
and are very much preferable. The
banana leaves may be kept drier than
the grass, Grass has a tendency to
absorb moisture and to hold moisture
149

and dampness, and that causes the fruit
to sweat and causes the ‘Ripe Rot” to
develop, the fruit to turn black and to
soften. Mistakes were made, particu-
larly in the Hilo banana trade, in ship-
ping the fruits in moist grass, On the
mainland last summer I found a banana
drum being used for the shipping of
bananas from the great central markets
into the tributory territory. These
drums were constructed of heavy card-
board, and were just large enough to
contain a single bunch. They are made
of two sizes, large enough to contain a
single bunch. Around the top of the
drum the top hoop held a strong piece
of paper in place, which was drawn up
from the top of the drum and tied to
the stem of the banana, and that
was the way in which the fruit was
carried—by its stem, Whether that
would be practicable for our shipping
Ido not know. I have sent for some of
these, and we hope to have them on
hand and give them a closer examination,
and possibly we may be able to give
them a trial. They are also making a
similar drum ont of veneer instead of
the paper. Refrigeration is absolutely
not adapted for the banana. Bananas
shipped in refrigeration turn black and
never ripen. The‘ banana trust,” as it
is called—the United Fruits Company—
ship their bananas across the hot plains
in the summertime with ice—in the ice
bunkers of the refrigerating cars—but
they are always watched; frequently
the doors are opeu, the ventilators are
opened. These trains are always accom-
panied by an attendent, who sees to it
that the temperature never gets down
below. The ice is simply to overcome
the intense heat and hold back the
ripening a little.
The Bluefields versus the Chinese
variely for shipping.—The Chinese
banana, as you know, is very subject to
what is known as the “Ripe Rot”
disease. That is the fungus disease that
causes the banana to become spotted,
speckled with little black specks. When
the disease spreads and the black specks
become united, it forms large blotches,
which in the last stages of the disease—
I mean the fruiting stages of the fungus
—produce a reddish, roseate tinged spot
where the black spot was previously.
That you may not have noticed, but if
you will get some bananas and allow
them to ripen and rot, if they have these
black spots I think you notice finally
this red fruiting stage of the fungus.
The Bluefields banana is quite resistant
to the disease and, as a consequence, it
arlives in the market in a bright yellow
form. Sometimes you see black spots
on them where they have rubbed to-
Edible Products.
gether or where they have rubbed
against the next bunch, because they
are shipped naked, without any wrap-
ping, but this is due to bruising. The
Bluefields or Jamaica variety holds to
the bunch better than the Chinese.
There has been a complaint against some
of those that we have grown here.
Though that complaint may be due in
part to our soil and climate, I believe
that it has been due to hanging the
bunches the wrong way. The Chinese
banana is hung in one direction and the
Bluefileds in another, as I will show you
in the slides later. A Bluefields banana
hangs close up to the stem of the bunch,
and as it grows from the tree, the in-
dividual fruits come out like that
(indicating)and goup. Now if you hang
the bunch up that way in the market,
when the fruits begin to ripen, the
weight simply breaks them off; if you
reverse the thing—hang them up by the
smaller end—they hang more naturally
and their weight is a pull rather than a
thrust and they will stand it.
The capacity of the pacific coast for
bananas, as nea as Iam able to estimate
it from the information which I have
gathered in many cities on the western
slope, is about 826,000 bunches per annum,
and of these Hawaii ships about 15,000
bunches a month. You will see that our
competitors ship a great many more
bananas all the way from New Orleans
or Mobile than we ship from here, and
pay high freight rates on them, too.
There isa freight rate of about $1:25a
hundred, if I recallit, from New Orleans
to any pointon the Pacific coast. The
cooking bananas have not got into the
market at all. I believe there is an
opening for cooking bananas in the
markets. Some of our ‘‘maia maoli,”
the variety that is most commonly used
for cooking, the common cooking banana
of our markets, I believe would find a
ready sale in the mainland markets if
the people ever became acquainted with
them. There certainly is no fruit more
delicious when properly cooked thana
‘*maia maolli.”
THE PINEAPPLE.
There are a great many points to be
considered in the proper shipping of
pineapples. Here, again, I want to
emhpasize the matter of the care of
handling. The packing of a ton or a
ton and a half of pineapples on a wagon
loose, rubbing against each other, over
rough roads and perhaps without springs
on the wagon, certainly is not the
advantage of the fruit. In all experi-
ments we have found that pineapples
cut with long stems carry to the market
in very much better condition than
150
[FeBRUARY, 1909,
those that are cut with short stems.
Now, as to packing: At the present
time the large portion of our pine-
apples that go to the market as fresh
fruit are packed in a erate that is in
my opinion entirely too large for the
fruit. We have the most delicate, the
most delicious and the largest fruit, the
best pineapples that are commonly
found in the markets. We put them
into the largest crate—the largest
package—of any pineapples that go
into the market. We are at the ex-
tremes in both ways: the best fruit,
the poorest package. Several attempts
have been made to use other erates,
and some of them are an improvement.
There is a crate devised by Mr.
Byron O. Clark (who is present with
us,to-night) which is an improvement
in that it contains much less fruit and
has rounded corners so that it does
not receive as many opportunities to
have the staves split off. It comes as
near the advantages of the round or
barrel form of any crate that we
have tried. As to packing material,
there appears to be very little differ-
ence whether we use excelsior or dried
wild grass, provided the latter is per-
fectly dry. ‘The danger with grass is
in using it when it is not perfectly dry.
The paper wrapping should be heavy,
and as in the case of the papaia, it is
better that it should be glazed. Hach
wrapper should be large enough to
cover the whole fruit, including the
base, but not necessarily the crown;
it can be pressed about the crown and
made tocover the stem. It is import-
antthat there should be a solid pack,
There is nothing here (on the black-
board) in regarding to shipping, but I
believe that that is our most import-
ant problem at the present time, that
is, to get suitable shipping facilities.
What we need is steamers that will
carry the fruit with gcod ventilation,
keep the fruit cool and keep the circu-
lation of air about it. Another need
of equal importance is an organization
which can place in the important main-
land market representatives to handle
our fruits, an organization to act as
the representative of the Hawaiian
growers. What [ am saying nowin
regard to pineapples applies to every
fruit that I have discussed, but it is
most practicable at the present time in
the case of pineapples, because that in-
dustry has grown to assume such large
proportions, Icannot stop to tell you
all the reasons for this. I have brought
here a number of bulletins at Mr. Pope’s
suggestion, bulletins covering the sub-
ject of citrus fruits, which I have
discussed with you, and also the mango,
FREBRUARY, 1909, |
and this bulletin on the marketing of
Hawaiian fruits. In the latter part of
this you will find’something of my ideas
in regard to the marketing systems and
the absurdity that appears to me to be
involved in the so-called ‘‘Commission
System ”’—‘‘ consingnig system,” and a
better system whichI think ought to
be inaugurated. I think we will take the
few minutes that remain to run through
a few of the sildes which will illustrate
some of the things which I have said.
A number of slides of the different
fruits were then exhibited, with explan-
ations by Mr. Higgins.
In answer to a question as to the
advantage of sealing the ends of various
fruits with sealing wax or other sub-
stances to prevent diseases, etc., the
speaker said that it had not as yet
been determined definitely whether
such sealing was an advantage or not ;
that experiments would have to be
conducted with the different fruits and
sealing materials to decide that point.
The advantage would bein preventing
infection, but in many cases the spores
would have gained entrance before the
sealing process had begun.—Hawiian

TIME FOR DIGGING SWEET POTATOES.
The harvesting and marketing of
sweet potatoes direct from the field
begins about the middle of August and
continues until the crop is all disposed
of or placed in storage for winter
marketing. During the early part of
the harvesting season the yield is light,
but us arule the prices paid are good.
The supply for home use and _ those
potatoes that are to be kept in storage
should not be dug until just before frost.
In the localities where frosts do not
occur until quite late in the season the
sweet potatoes ripen and the vines show
a slight tinge of yellow when ready for
handling.
EFFECT OF FROST ON SWEET POTATOES,
The foliage of the sweet potato is very
tender and is easily injured by frost.
A light frosting of the leaves will do no
harm, but should the vines become
frozen before digging they should be
cut away to prevent the frozen sap pass-
ing down to the roots and injuring
them. Where there is a heavy yield of
potatoes the soil is frequently cracked
or the ends of the potatoes protrude
above ground and are liable to injury
from severe frost.
151
Hdible Products.
If on account of rainy weather or for
any other cause the potatoes cannot be
dug before frost or immediately after-
wards, the vines should be cut away
and the potatoes removed at the first
opportunity. If cold weather continues
it may be necessary to draw a little
extra soil over the hills to protect the
potatoes, or the vines may be piled in a
ridge over the row. A very slight frost-
ing of the potatoes will cause them to
decay within a short time after being
placed in storage.
METHODS OF HARVESTING SWEET
POTATOES.
For digging a small area of sweet
potatoes, the spading or potato fork jis
suitable. When digging by hand, the
work will be greatly facilitated by first
throwing a small furrow from one side
ot the row by means of a one-horse turn-
ing plough. The removal of sweet pota-
toes from the soil in large quantities is
generally accomplished by the aid of
sweet potato diggers or ploughs. These
implements are provided with two
sharp rolling coulters that cut the vines
ahead of the plough, and differ from the
ordinary plough in having a moldboard
that does not turn a furrow and termi-
nates ina number of rods or an exten-
sion of the moldboard for separating the
potatoes from the soil.
Where no special digging device is
available, the ordinary two-horse turn-
ing plough is frequently used, a rolling
coulter being attached to the beam to
cut the vines. After ploughing out the
sweet potatoes it will be necessary to
stir the soil in order to fird those that
become covered, The machines em-
ployed for handling Irish potatoes may
be used for digging sweet potatoes, but
are not entirely satisfactory for this
purpose, as they bruise and otherwise
injure sweet potatoes.
It is desirable that the soil should be
comparatively dry at the time of harvest-
ing sweet potatoes, and bright, drying
weather is essential to the proper hand-
ling of the crop. Sweet potatoes differ
from Irish potatoes inthat they are not
so easily injured by sunlight. However
they should not be exposed for any
length of time if the sunshine is very
warm. During the handlingin the field
it should be the purpose to remove all
soil and surface moisture from the pota-
toes. Sweet potatoes should not lie
exposed upon the surface of the ground
during the night.
MARKETING DIRECT FROM THE FIELD.
Where sweet potatoes are grown in
large quantities for early marketing
it is the practice to dig, pack, and load,
Rdible Products.
all on the same day, direct from the
field. As the potatoes are gathered up
behind the diggers they are sorted into
the various grades and packed into
ventilated barrels ready for — ship-
ment, When the barrels are packed
in the field they are as a_ rule
covered with burlap or similar material.
In parts of New Jersey the potatoes are
sorted in the field and gathered into five-
eighths-bushel baskets, in which they
are hauled to the depot platform, where
they are packed into bariels and headed.
More than one-half of the commercial
crop is marketed direct from the_field
without the use of packing sheds or
storage of any kind other than that
provided by the transportation com-
panies.
GRADING AND PACKING,
In sorting sweet potatoes preparatory
to packing, about four grades are recog-
nized as fancy, primes, seconds, and
eulls. Those packed as fancy include
only the most select, both in size and
shape. The primes include all those
adapted to general first-class trade,
while the seconds include the smaller
and more irregular stock which goes to
a lower priced trade. The culls are not
marketed unless good stock is exceed-
ingly scarce, andasa rule are used for
feeding to hogs.
Sweet potatoes are usually shipped in
barrels holding eleven pecks each. Some
markets require that the barrels be
faced and headed, while for others the
tops are slightly rounded and covered
with burlap. Small lots of extra-fancy
sweet potatoes are sometimes shipped
in one bushel-crates having raised tops :
also in patent folding crates.
Throughout the process of handling
care must be exercised to see that the
sweet potatoes do not become bruised,
for upon this their shipping and keeping
qualities greatly depend.
STORAGE OF SWEET POTATOES.
Methods of Storing.
Unlike most perishable products, the
sweet potatoe requires warmth and a
dry atmosphere while in storage. The
method of storing will depend both upon
the locality and the quantity of potatoes
to be cared for. The temperature and
conditions of a rather living room are
admirably adapted for keeping sweet
potatoes intended for home use in the
North, while in the South they may be
placed in pits or stored in outdoor
cellars. The home supply may be placed
in crates and stored inaloft over the
kitchen part of the dwelling. Sweet
potatoes should not be stored in bags or
in barrels without ventilation.
152 {PEBRUARY, 1909.
PITS AND CELLARS.
Where large quantities of sweet
potatoes are stored for winter market-
ing, the method employed in the
Southern States is to place them in out-
door pits and cellars, while at the North
some form of heated storage house will
be required. Whether the storage be in
pit, cellar or house, a dry, warm atmo-
sphere with ventilation is essential to
good keeping.
Storage pits should be located where.
the drainage is good. First, a little of
the surface soil is thrown back to form
a level bed 8 or 10 feet in diameter, then
two small trenches crossing each other
at right angles in the centre of the bed
are excavated and some boards laid over
these. At the point where the trenches
cross, a loosely nailed 4 by 4 inch box
is set on end to form a flue up through
the potatoes. The earth floor of the pit
should be covered with2 or 3 inches of
hay, leaves, or pine straw, and the
potatoes piled ina large, conical heap
around the ventilator flue. When the
heap is of the desired size, the potatoes
are covered with hay or pine straw, and
soil to the thickness of 5 or 6 inches is
added, but the trenches and flue are
kept open until it is necessary to close
them to keep out the frost. In the
South sweet potatoes are frequently —
kept throughout the winter by this
method.
OUTDOOR CELLARS.
This form of cellar, built entirely
above ground, consists of a line of posts
through the centre supporting a ridge
pole upon which is placed one end of
planks or puncheons with their opposite
end resting on the ground on either side
of the ridge. The ends of the inclosure are
boarded u2, adoor being provided in one,
and the structure covered with sod to a
thickness of 5 or 6 inches. The sweet
potatoes are stored upon the earth floor
aud the door is kept open for a time for
ventilation. If the house exceeds a
length of 12 or 14 feet, a top ventilator
should be provided.
VARIGTIES OF SWEET POTATORS.
Of the large number of varieties of the
sweet potatoe there are not more than
ten that are now of great commercial
importance in the United States. For
the market that requireadry, mealy-
fleshed potato those varieties belonging
to the Jersey group are suitable. For
the southern trade and where a moist-
fleshed potato is desired these commonly
designated as yams are in damand.
Among the Jerseys that are extensively
grown are the’ Big-Stem Jersey, the
Yellow Jersey, and the Red Jersey.
FEBRUARY, 1909.]
The principal varieties of the yam group
are the Southern Queen, the Pumpkin
Yam, the Georgia, the Florida, and the
Red Bermuda. Of the varieties men-
tioned there are a large number
of special strains, known under many
local names.
In the selection of varieties for home
use one must be governed largely by
locality. Asarule those of the Jersey
group will thrive farther north than
those of the so-called yam types. For
market purposes the particular variety
or strain grown in the vicinity should be
first selected, and afterward other
varieties may be experimented with ina
small way.
The following brief descriptions of a
few of the leading varieties may be
of assistance in selecting those best adap-
ted to various conditions of soil and cli-
mate :—
Big-Stem Jersey.—This variety is the
most popular among the growers who
are supplying the northern and eastern
markets. It is a form of the Yellow
Jersey, having been selected for its pro-
ductiveness and dry, yellow flesh. The
vines are slender and long; the potatoes
are of spindle shape and inclined to grow
rather large; colour of potatoes yellow ;
colour of flesh light yellow or deep cream.
While this variety yields heavily. it is
unfortunately a rather poor keeper, and
its flesh is inclined to become dry and
“punky” toward spring, It will thrive
well toward the north, but is better
adapted for use as acommercial variety
than for home consumption.
Yellow Jsrsey.—The vines of the
Yellow Jersey variety are long and more
slender than those of the Big-Steam
Jersey, and the potatoes are of spindle
shape, but much smaller; otherwise the
two varieties are very similar in
appearance. The flesh is dry and mealy.
This variety is a fairly good keeper and
retains its quality well. Itis adapted for
home use and thrives under a wide range
of conditions, but does not yield heavily
enough for commercial purposes,
Red Jersey.—This is similar to the
Yellow Jersey variety, except that the
roots are red anditis more productive
under most conditions. It is suitable
for home use.
Southern Queen, or Hayman.—The
vines of this variety are strong and vigor-
ous; the potatoes are large, thick, and
blunt at ends or of short spindle shape;
the colour is white or light cream, while
the flesh is of cream colour, becoming
darkened in cooking, moist, and very
sweet. This variety ismost extensively
grown for market purposes where a
18

Edible Products,
sweet, moist-fleshed potato is demanded.
The Southern Queen yields well, is an ex-
cellent keeper, and is adapted for both
marketing and stock feeding and for
home use in the South Atlantic and Gulf
Coasts States, but it does not mature
when grown in the extreme North.
Pumpkin Yam.—The vines are vigor-
ous, short, sometimes of a bunch habit.
The potatoes are of short spindle shape
or quite round, witha dull yellow colour
on the outside. The flesh is orange or
sometimes yellow and marbled with
orange; it is moist and has a flavour very
similar to that of good squash, This
variety yields well and is adapted to
home use and to stock feeding throughout
the South.
Georgia, or Split-Leaf, Yan.—The vines
of this variety are slender and long; the
potatoes of medium size, spindle shape,
yellow, the flesh a light yellow, marbled
with salmon. The quality of this variety
is excellent and very sweet, but it isa
light yielder. It isa splendid sort for
home use throughout the South Atlantic
and Gulf Coast States.
Red Bermuda.—The Red Bermuda
vines are large and vigorous. The
potatoes are usually large and overgrown
with heavy ridges and veins. Thecolour
of the potatoes is rose red; flesh, creamy ;
quality fair but not so sweet as Southern
Queen. This variety is a heavy cropper
and suitable for feeding to stock. Itis
one of the fewso-called yams which
thrive in the northern portion of the
sweet. potato area.
Florida.—The vines of the Florida
variety are large and vigorous. The
potatoes are rather large, light salmon
yellow, smooth and regular, of short
spindle shape, with light yellow flesh.
This variety is not so sweet as the
Georgia and is inclined to be dry and
mealy. It yields fairly well and is
adapted for home use,
Pierson.—The vines of the Pierson are
similar to those of the Red Bermuda
variety. The potatoes are light yellow,
of short, spindle shape, very rough, with
cream-colored flesh. This sort is exten-
sively grown for the earliest market,
but itis of only fair quality. It yields
wellif allowed to remain until late in
the season.
Black Spanish, or ‘** Niger Choker.”—
The Black Spanish vines are very long,
vigorous, and dark purple incolour. The
potatoes are long, cylindrical, crooked,
or bent; dark purple in colour, with
snowy white flush and poor quality.
This variety is grown mostly for stock
feeding.

Shanghai.—The vines of the Shanghai
variety are large and _ vigorous; the
potatoes long, cylindrical; the outside
colour almost white, The flesh is
creamy white, becoming darker in cook-
ing. When baked the flesh is somewhat
dry and mealy and the flavour rather
poor. This variety yields fairly well
and is adapted for use as stock food in
Gulf Coast States.
Cost OF PRODUCTION AND RETURNS.
The cost of growing an acre of sweet
potatoes will vary with the cropping
plan and the extent to which the crop is
grown. On an average the cost of
growing an acre of sweet potatoes in the
regular commercial district is about as
tollows :—Rental of land, $8;, ploughing
and fitting, $5; fertilizers, $20 ; 10,000
plants, $10; planting, $5; cultivating, $9 ;
digging and marketing, $25; total, $78.
An average yield of sweet potatoes is at
the rate of one barrel to 100 hills or 100
barrels to an acre. The price per barrel
paid the grower is seldom less than $1°25,
and $2°50 or $3 is notuncommon. During
good seasons the net. profit from one
acre of sweet potatoes is about $75.
While occasionally the net returns are
from $100 to $150 an acre for a single
season, there are seasons of crop failure
or overproduction when very little, if
any, profit is realized.
The sweet-potato growers on the
eastern shore of Virginia asa rule plant
about 10 acres insweet potatoes, and this
constitutes their money crop. The
remainder of the cleared portion of their
small farms is devoted to corn, pasture,
and hay, all for home use. Here the
sweet potato crop is grown almost
entirely without the aid of hired help,
and the cost of production does not
exceed $40 an acre. Where the crop is
stored the gross returns are greater, but
the cost of production is increased pro-
portionately.
UsEs OF SWEEr POTATOES.
The uses of the sweet potato as
a table vegetable are too important
and too well-known to require more
than brief mention in a publication of
this character. In preparing them for
the table they are baked, boiled, fried,
or braised, while for pies they are used
inthe same manner as pumpkins.
A number of attempts have been
made to build up an industry for the
production and sale of desiccated sweet
potatoes and sweet potato flour. There
is doubtless a great field for this class
of goods, especially for export and for
ship supplies.
Usis For Stock Foon.
The vines of the sweet potato when
properly cured make a medium grade
’ produced,
of hay for feeding to cattle and sheep.
In the green state the vines are eaten
by sheep, cattle and hogs, but their feed-
ing value is comparatively small. The
potatoes are fairly well adapted to feed-
ing to range cattle, sheep, and hogs.
although their nutritive value is quite
low, and they require the addition of
cotton-seed meal or grain to make a
balanced ration. On farms where sweet
potatoes are grown extensively the
culls are fed to hogs, together with a
oue-third or one-half ration of corn.
By employing one of the heavy-
yielding varieties of sweet potatoes,
such as the Southern Queen or the Ber-
muda Red, and drying and pulverizing
them, a splendid stock food may be
duc especially when _ sufficient
grain is added to form a balanced ration.
The principal uses of sweet potatoes
are, however, for the table, and the de-
mand for this purpose is rapidly in-
creasing.
From the fact that by the aid of
commercial fertilizer alone sweet pota-
toes can be grown on comparatively
poor landand largely by the use of
labour-saving machinery, this crop may
in a great measure solve the problem
of how to occupy the ‘‘ worn-out” cot-
ton and tobacco lands of the South,
especially if employed in a rotation
including corn, peanuts and grass. By
the perfection of some means by which
sweet potatoes could bedried and con-
verted into a condensed stock food on
the farm, they in conjunction with corn,
peanuts, and a littie hay would serve
to keep the stock on southern farms in
good condition during the winter.
When removed fromthe ground the
sweet potato contains about 71 per
cent, of water, 1°5 per cent. of protein, 25
per cent. of nitrogen-free extract, and
0°35 per cent. of fat. It will be noted
that both the protein and fat content
of the sweet potato are compara-
tively low. The analysis of peanuts
shows that the protein and fat are both
quite high, and by combining them
with sweet potatoes at the rate of one
bushel of peanuts, ground in the shells,
to three bushels of sweet potatoes are
nearly equal to one bushel of corn in
feeding value, but in order to make
them satisfactory as a stock food it
is necessary to add peanuts, cotton-
seed meal, or grain.
USE FOR PRODUCTION OF ALCOHOL.
The starch and sugar content of sweet
potatoes varies considerably in differ-
ent varieties, but as a rule they con-
tain about 16 per cent. of starch and 4
per cent, of sugar, making a total of 20

er cent. of aleohol-producing material.
tis possible that sweet potatoes will
become one of thechief sources of de-
natured alcoholin the United States,
but at present the methods of manu-
facture have not been sufficiently per-
fected to warrant their use for this pur-
pose ona farm or community basis.—

A. B.C. OF LIME CULTIVATION.
(Concluded from page 42,)
HAND-PRESSED LIM® OIL.
_ Lime oil is used in perfumery and for
soap making. The hand-pressed _pro-
duct is obtained by pressing the limes
by hand over an ecuelle pan. The ecu-
elle is ashaliow, concave, circular cop-
per pan studded with blunt spikes on
its concavity and with a receptacle at
the base to catch the oil. The work of
obtaining hand-pressed oil is done by
women, who usually select the best limes
and pass them quickly with a circular
movement over the blunt spikes, ex-
erting sufficient pressure to break the
oil cells in the skin of the limes. The
oilruns into the receptacle and is col-
lected from time to time in bottles, It
is then settled, and afterwards is passed
through filter paper into copper vessels.
These vessels are usually exported in
boxes.
A barrel of limes will give from 3 to
44 oz. of oil by this process, and the
usual price paid for extracting the oil
is ld. per oz Atthis rate, women who
have become expert by practice at this
work are able during the height of the
crop season to earn good pay.
The yield of oil varies according to
conditions of moisture. In _ localities
where the annual rainfall is from 60 to 100
inches, the citric acid content of the
juice of the fruitis high, and the yield
of oil from the rind of the fruit low.
Where the rainfall is high—say, from 130
to 200 inches—the citric acid content is
low and the yield of oil high.
DISTILLED LIME OIL.
When lime juice is to be concentrated
it is first distilled in order to obtain the
oil. In thecase of estates which ship
raw juice, the scum that collects on the
juice in the settling vats is alone distilled.
The oil is exported in either copper or
tin vessels which are packed in boxes.
It costs less to produce than _ hand-
pressed oil, but commands a lower price.
Stills fitted with steam coils are the
best, but itis only in a very few cases
that steam is available on estates.
55 KHdible Products.
The yield of oil by distillation is from
3 to 50z. per barvel of limes, or taking
80 barrels of fruit to make one hogshead
of concentrated juice, from"15 to 25 Ib,
per hogshead, according to locality and
conditions of moisture. A gallon of
distilled oil weighs 9 lbs.
Appendix I.
CITRATE oF LIME.
The following information on citrate
of lime has been obtained by the Impe-
rial Department of Agriculture from
manufacturing chemists in London and
New York :—
Messrs, Sydney Harvey & Co., 48,
Mark Lane, London, E.C., write as
follows :—
‘Citrate of Lime is preferred to con-
centrated juice by our acid makers,
because the tormer is more easily worked,
and is altogether a more satisfactory
article to deal with, and to the producer
himself, citrate of lime is also a better
article. In the first place, a higher
price is paid for citrate of lime than for
juice, and there is a considerable saving
in freight, casks, and loss by leakage.
‘Up till a few years ago, the whole
of the Sicillian production was in con-
eentrated juice, but when the makers
once realised how much more satis-
tactory citrate of lime was, the making
of concentrated juice ceased entirely,
and now we receive from Sicily some-
thing like 5,000 tons of citrate of lime.
‘There is no chance whatever of the
demand for citrate of lime falling and
returning to concentrated juice, We
believe that more citric acid can be
saved in making citrate than in concen-
trating juice.’
The Powers-Weightman-Rosengarten
LORRY Philadelphia, write as fol-
OWS :—
‘The cost of a citrate plant cannot be
very great, and we believe the money
spent in installing the same would be
quickly returned through the increased
economy and efficiency.
‘Citric acid contained in citrate of lime
sells at a higher price than that con-
tained in concentrated juice. We would
give preference to citrate as against
concentrated juice, and the tendency is
strongly setin that direction and will
remain so.
‘We have never determined — the
saving in making citrate, but have
always considered it to be at least 10 per
cent.’
Edible Products. 156
The following circular on citrate cf
lime isissued by the above Company :—
‘In some places citrous juices are
simply concentrated in copper kettles
over an open fire. This concentrated
juice is placed in suitable containers and
shipped to us. We cannot recommend
concentration, as some of the acid is
destroyed, and the evaporated juice is
not as valuable per unit of citric acid
contained, as the product we now des-
cribe, viz., calcium citrate.
‘Calcium citrate is a combination of
calcium and citric acid. Its most useful
property is the fact that it is in-
sOluble in hot water; hence, when the
proper calcium salt (chalk, whitening or
slaked lime) is added toa boiling liquor
containing citric acid, the liquor is
robbed of its acid, and the latter is
recovered in the form of calcium citrate.
‘It is necessary to have a steam boiler
useful for generating steam rather than
for power; the steam from this boiler is
used :—
1. To heat the juice in a still in order
to drive off the oil.
2. To keep the juice boiling hot whilst
it is converted into calcium citrate.
8. To heat water with which the
calcium citrate is washed.
4. To heat the driers

‘We now describe the method for
producing calcium citrate from limes,
waste lemons, etc. This method might
be subject to changes according to con-
ditions with which we are not at present
familiar.

The material is pressed between the
rollers of an old sugar mill; a cider press
will also sutfice. The juice is run into
the still (made of copper or lead), where
a short boiling removes the oil which is
eollected at the end of a copper con-
denser ; the boiling juice is run through
strainers made of brass wire into suitable
wooden tanks, where it is neutralized
with chalk of lime ete. During neutral-
ization the mass is kept as hot as
possible by means of a jet of live steam.
‘When the operation is complete the
contents of the tank are permitted to
settle; the clear liquid is syphoned off
and run away, boiling water is added to
the sediment, steam permitted to play
through the mass; and after permitting
settlement, the wash water is run away.
The hot mass is now run into filter bags,
which are securely closed, and placed in
a convenient press (a cider press is
sufficient). The expressed pulp is now
placed on the driers, and when dry is
packed into suitable containers,

[FEBRUARY, 1909.
‘The drying is carried out in flat,
deuble-jacketed pans, made of wrought
or cast iron, which areso arranged that
the pulp may be easily worked over
with a spade and thoroughly dried.
‘The difficult part of the operation is
to ascertain the point of neutralization,
viz., that point when enough chalk or
lime has been added to ensure full
combination with the acid, and yet not
enough to causea great excess. With
a little experience this point is easily
found by testing a sample of the contents
of the vats. A sour taste indicates that
the acid has not all been converted into
citrate, and more chalk must be added.
When the sour taste is replazed by a
distinctly disagreeable characteristic
taste, the acid has been removed from
the liquor.
‘A further test is to take from the vat
a sample of the clear liquor and also a
sample of the sediment. If, when more
chalk is added to the hot sample of clear
liquor, effervescence takes place, there
is still free acid in solution,
‘If, on the other hand, hot raw juice
isadded to the sediment and decided
effervescence takes place, there is an
excess of chalk present.’

CULTIVATION OF LIMES AT MONTSERRAT.
The following particulars have been
supplied-by Mr. W. Robson, Curator of
the Botanic Station, Monsterrat :—
The plantations are chiefly confined to
the sheitered valleys aud slopes of the
lower lands. In addition to the natural
shelter, belts of white cedar (Tecoma
leucoxylon) are frequently used. This is
practically the only plant used as a wind
break, and it is planted at distances of
about 150 yards, either in single rows or
in double rows about 4 feet apart.
Seeds are sown in small nursery beds
and remain there until ready for trans-
ferring to the field. No transplanting
into nursery beds is done. In some
instances planting is successfully done
at stake in the field, when several seeds
are sown at each stake and only the
most vigorous of the seedlings allowed
to grow.
Showery weather is chosen for plant-
ing, and small beds are made with a fork
in which to put the plants. A distance
of 18 feet by 18 feet is the most general
for planting, although in the drier dis-
tricts 12 feet by 12 feet is practised.
For the first two years of growth,
cotton has been successfully grown as a
catch crop.
FEBRUARY, 1909.)
Hoeing isdone at intervals of about
six weeks or two months, and in the dry
season more frequently. The method of
keeping a circle clean around each tree
and cutlassing the remainder of the field
is not adopted on Montserrat planta-
tions.

Exports oF LIME PRopUCTs.
Details of the exports of lime products
from the Islands of Dominica and Mont-
serrat are given in this Appendix in
tabular form.
Table I. gives thelime products from
Dominica for the years 1892-1895 inelu-
sive. Exports of concentrated juice,
raw juice for cordial, hand-pressed oil,
distilled oil, pickled limes, and green
_ limes are given. In addition to these,
222 gallons of lime cordial of a value of
£33, and 733 ewt. of citrate of lime
valued at £1,503 were exported in 1906,
and 6,352 gallons of cordial, of a value of
£958, and 2,388 ewt. of citrate of lime, of
a value of £7,761 were shipped during
1907. These amounts have been included
in the total values that are given for
these years.
There are also given in this table
columns that show the total estimated
crops of the several years in barrels of
lime fruits and in gallons of lime juice.
In 1892 itis estimated that 58,616 barrels
of limes were produced, while in 1902
this had inereased to 249,178. In that
year, however, a severe gale and attack
of scale insects affected the lime cultiva-
tions to such an extent that the crop of
1903 was nearly 50 per cent. less than
thatof the previous year. A gradual
recovery has been made since then, until
in 1907 we find that the cropis estimated
at 272,229 barrels.
Table II. gives the exports of lime
roducts for Montserrat for the years
1892-1907. Where figures are not given,
information has not been obtainable.

WHAT FORESTRY HAS DONE.
The following extract is reprinted
from Circular 140, Forest Service, U.S.
Department of Agriculture :—
(Continued from page 450, Nov. 1908.)
AUSTRIA AND HUNGARY.
AUSTRIA.
In Austria, which has been independent
of the German Federation only since
1866, forestry has, in the main, followed
German lines. Austria-Hungary is one
of the largest exporters of wood, and the
yearly exportations reach 3,670,000 tons.
Germany takes more than halt of tthe
exports, and the rest is distributed to
Italy, Russia and Switzerland.
Austria has 24,000,000 acres of forest,
of which only 7 per cent. belongs to the
State and 58 per cent. is private land.
Communal and entailed forests make up
the remainder. Of the private forests
34 per cent. is in estates ranging from
20,000 to 850,000 acres in area, and for
the last fifty years at least 75 per cent. of
the total forest area has been held in
large, compact bodies. These large
blocks are naturally favorable to forest
management. Private forestry is further
encouraged by the system of forest
taxation, which relieves forests in
which forestry is practiced. In the
United States there are many enormous
private forest holdings on which forestry
would unquestionably be practiced were
it not that excessive or ill-devised forest
taxation effectually discourages it.
The total net revenue from the
Austrian State forests is over $5,000,000.
The net yearly revenue per acre of 21
cents is comparatively low, due mainly
to the facts that only fifty-six cents per
acre is expended upon the forest, and
that most of the area is located in the
rugged Alps and Carpathians, where
administration and logging are costly.
The present forest department was
started in 1872 in response toa popular
outery against the policy of selling
State lands. That policy resulted in
reducing the area of State forests from
10,000,000 to a little over 7,000,000 acres
during the first half of the nineteenth
century. The administration was re-
organized in 1904, and now has three
departments—administration proper, re-
forestation and the - correction of
torrents and forest protection.
Forestry is successfully practised on
60 per cent. of all the Austrian forests
and on 82 per cent. of the private forests,
and excellent results have been secured
by co-operation between the State and
private persons in forest management,
particularly under the law of 1888. The
most conspicuous fruit of Austrian
forestry, however, is the reforesting of
the ‘ Karst.” The karst was a stretch
of barren lands in the hilly country of
Istria, Trieste, Dalmatia, Montenegro,
and neighbouring territory along the
shores of the Adriatic Sea. It comprised
some 600,000 acres. Kor centuries it had
furnished the ship timbers and other
wood supplies of Venice, but excessive
cutting, together with burning and
pasturing, the evil results of clearing,
and the natural condition of the land,
had left it a waste almost beyond re-
covery. Many laws had been passed
from time to time to stop the forest
havoe, but without real effect till 1865.
In that year the Government, persuaded
by the Forestry Association, began to
offer help to landowners who would
undertake forest planting, Taxes were
remitted for periods of years, technical
advice was given, and plant material as
well as money was supplied. Further
laws were found necessary in 1882 and
1887 to meet the objection of stockmen. -
A6 the present time over 400,000 acres, or
two-thirds of the Karst, have been
brought under forest, in part by plant-
ing, at a cost of from $8 to $10 an acre,
in part by protection and the natural
recuperation so made possible.
This work has been carried on under
the direction of the ‘‘forest protective
service,” which was first created for
Tyrol in 1856 as a result of floods in the
Tryolese Alps in 1851, and was later
(1871-1874) extended to the rest of the
Empire. This service, which is distinct
from the State forest administration,
has also been especially helpful in
encouraging private forestry. Though
at first regarded with hostility, it
is now held in high regard on the
strength of the work it has done and is
doing.
Harmony of interest between the State
and private forest owners, which the
whole Austrian forest policy favours, is
notably secured by the encouragement
of the wood export trade through such
provisions as reduced freight rates, the
absence of export duties, and moderate
forest texation.
A ‘“‘reboisement” or reforestation law,
based on that of France, was passed in
1884 to control torrents. - This law
carries an annual appropriation of
$100,000, and the planting work, like that
FEBRUARY, 1909.}/
on the lands of the Karst, is carried on
under the direction of the “‘ protective
service.” For the regulation of the
lower rivers $1,350,000 was appropriated
at the same time, and of this sum $400,000
has been successfully expended on _ re-
forestation.
HUNGARY.
Hungary has 23,000,000 acres of forest’
of which the State owns 16 per cent. ;
corporations, 20 per cent,; churches,
cloisters, and other institutions, 7'5 per
cent,; 4nd private persons the remain-
der. From $10,000,000 to $12,000,000 worth
of wood is annually exported.
About half of all the Hungarian
forests are under working plans, by
which the eut is regulated so as to
provide for a sustained yield, and the
present annual cut of 1,000,000,000 cubic
feet is believed to be considerably less
than the wood actually produced. The
State forests yield $600,000 net annual
revenue.
The management of all co-operation
and protection forests has been super-
vised by the Government since 1879,
and all so-called ‘absolute forest land,”
in other words, land unfit for farming,
must be reforested within six years
after itis cleared. Three-fourths of all
the forest land of Hungary, including
private as well as_ public forests, falls
under the classification of absolute
forest land. Moreover, all mountain
forests are required to be managed
under State working plans. Two-thirds
of all the Hungarian forests are brought
under this sort of State supervision.
Forest planting is encouraged by State
nurseries, at which 10,000,000 seedlings
are raised every year for free distri-
bution and by bounties paid for forest
Pen established on private waste
ands.
Hungary has some 600 square miles of
shifting sands and waste lands, like
those of the Landes of France. The
work of reclaiming these was planned
by the law of 1788. Actual planting was
begun in 1817. By 1869, 20,000 acres had
been forested, and parts of the planta-
tions were beginning to yield a profit.
The work of reforesting is constantly
going on.
NORWAY, SWEEDEN AND DENMARK.
Norway.
Only 21 per cent., or 20,000,000 acres of
Norway is in forest. The State owns
less than 2,000,000 acres of this. Of the
forest region one-half has to import
timber, one-fourth has sufficient for its
needs, and one-fourth is able to export
over 1,000,000 tons, valued at $18,000,000 a

year. Nearly two-thirds of the exports
goto England, and most of the rest is
divided up between Belgium, Australia,
France, Holland, Germany, and Den-
mark. The total annual cut, one-fifth
of which is exported, is about 500,000,000
cubie feet. It exceeds by 1,500,000 cubic
feet the amount of wood grown by all
the forest in the same time. In other
words, the cut is far too heavy to last,
so that a reduction of wood exports is
inevitable,
Forestry ic onalow level. The various
provisions for the better use and pro-
tection of the forests which began three
hundred years ago, have been of too
half-hearted a nature to meet the situ-
ation. There is a forest service, but the
officers are few and underpaid, and the
districts under their care—sometimes
several million acres to each—are far
too large for effective work. Moreover,
there are difficulties over the forest
rights which were earlier granted to
encourage the development of the
country, but which are now greatly in
the way of establishing property rights
and organizing an administration.
Since 1860 the State has been buying
cut-over lands in order to plant them to
forest where forest protection is needed,
and from $15,000 to $20,000 a year has
been spent in this way during recent
vears.
The communal forests are supervised
by the Government, and are usually
managed by the foresters with a view
simply to supplying local needs. Sale
outside the parishes are permitted only
where there is more than enough for
these needs.
SWEDEN.
Sweden has nearly 50,000,000 acres of
forest, covering nearly 50 per cent. of
the total land area. Since the English
import duties were abolished in 1866,
the wood exports from Sweden have
steadily increased, till now Sweden
stands next to Russia, the world leader,
in wood exports with $54,000,000 worth
a year, representing nearly 4,500,000 tons.
England takes half of this, followed by
France, Denmark, Germany, Holland,
Cape Colony, Australia, and ..South
America. The total cut from the forest
" estimated to be near 1,000 million cubic
‘eet.
The State owns about 13,500,000 acres,
or 32:2 per cent., and controls 4,000,000
acres more. The State lands are, in the
main, of lesser commercial value, and
this fact, together with the existence
of logging rights granted in the past,
keeps the net income for the present
down to 12 cents anacre, Nevertheless,
Timbers, 162
since 1880 the net revenue from the State
forests has risen from $300,000 to nearly
$2,000,000 a year.
Up to five hundred years ago Sweden
was overburdened by forests, but by
that time cutting and wasting had gone
so far that the wilful setting of forest
fires was forbidden. In 1638 overseers of
communal forests were appointed in
order to conserve supplies of wood for
charcoal used in the iron industry. A
general law followed in 1647, and a
director of forests in the two southern
districts was appointed in 1720. All
through the eighteenth century restric-
tions upon forest use were in force,
Toward the close of the century there
was, indeed, a premature scare over a
possible timber famine. Yet, despite
this legislation, and much legislation
which followed, waste continued to go
on. While measures were being passed
to conserve the forests, the communal
forests and town forests were actually
being sold. It was not till the law of
1903, which went into effect in January,
1905, that a satisfactory policy was
secured. In geueral, this requires the
practice of forestry. Asin Russia, pro-
vincial forest protection committees
have to approve the local felling plans.
A diameter limit is set, below which
trees may not be cut. Clearings are
forbidden and cleared land, unless used
for other purposes, must be reforested.
Pasturing is restricted where it would
do harm.
In the past thirty-five years the State
has increased its forest holdings by 45 per
cent. through the purchase and reforest-
ing of wastes and sand dunes and by the
settlement of disputed titles. The pur-
chases amount to over 600,000 acres, for
which an average price of $5°30 an acre
was paid.
Lumbering is carried on much as it is
in the United States. The State, as a
rule, sells stumpage, and the timber is

removed by contractors. Management
is by no means so detailed and intensive
as in Germany or France. The trees
which are to be cut are marked, but no
attempt is ordinarily made to prepare
complete working plans. Only a
moderate amount of planting is done to
secure the future crop, and natural
reproduction is mainly relied upon.
Forest fires continue to do great
damage, especially in the northern part
of the country. A forest patrol is doing
effective work, however, in checking the
spread of fires.
DENMARK.
Denmark has about 600,000 acres under
forest, of which the State owns over 23
per cent., or 142,000 acres. About 75,000
acres of wastes are in process of reforest-
ation.
The need of wiser forest use was felt
in the eighteenth century, and by 1781
the State forests were placed under
administration. But the clearing of the
forest continued at sucha rate that in
1805 it was provided that the still exist-
ing forests of beech and oak should be
maintained forever. Further, provision
was made as tothe selling of the pea-
sants’ farms, so that they should not be
accumulated in large holdings
which the peasants would have to
depend for their wood.
Since 1820 the forest area has been
increasing. At present reforesting is
adding to it very considerably. Nearly
200,000 acres of heath have been planted
in the last forty years. To this work
of reclamation the State contributes
$40,000 a year.
In State forests, as well as i nthe com-
munal forests and the farmers’ woodlots,
forestry is carefully and profitably prac-
tised.—Hawatian Forester and Agri-

PLANT, SANITATION.
THE TEA INDUSTRY.
THE MOSQUITO BLIGHT.
By C. B. ANTRAM,
Entomologist to the Indian Tea
Association.
From past observations and our ex-
periences of the year 1907, with regard
to Mosquito blight, it would seem that
everything depends upon the climatic
conditions prevailing during the first six
or seven months of the year, whether
the pest becomes serious or otherwise
from about July onward to the end of
the season. Without doubt the blight
has this year been as serious as in any
year since its first discovery, and in July
reports began to come in from nearly
every part of the tea districts that
‘* Mosquito” was damaging the bushes to
such a degree, that certain gardens were
practically closed for the remander of
the season. This was’the case, not only
in one corner of a district, but in several
widely separated portions of the whole
tea area, the blight generally being, on
most gardens, worse than in previous
years. In one or two instances only
(where the insect had in past years given
trouble) were the reports tavourable in
that there had been no appreciable loss
incrop. The following extracts from
letters received from planters giving
their opinions as to the reason for the
current year’s excessive attack of Mos-
quito blight are interesting and point
tothe one idea that “ Blight” is con-
trolled in a very great measure by
climatic influences, —
ONE CAUSE oF Mosquito BLIGHT.
One Manager writes from Assam,
under date the 24th September, 1907 :—
“IT am of opinion that the cause of
Mosquito blight appearing so early and
in such a severe form this season is
entirely due to weather conditions. The
cold damp weather which prevailed
during the months of May, June, and
July, seems to have been especially
favourable to the successful develop-
ment of the pest, and were it not for the
fotunaie occurrence ofa spell of sun-
shine and heat in August which checked
its progress, the loss of crop would have
been considerable. As it is, I only
estimate a loss of about 200 to 300
maunds, while in the last five years the
loss has been nominal. Bar a few
isolated patches, at the end of each
season, the pest has done little or no
harm here for the last seven years, [|
may mention that the temperature for
the last five years has not been so low
in May, June and July, as it has been
this year. My experience is that absence
of sunshine is invariably favourable to
the development of the pest.”
Another planter writes:—This year
is one of the worst in this district (Dar-
rang) for Mosquito blight since 1902, the
weather being socool and dull for the
last three months until the 11th August
when we had a change,” ete.. etc.
It is quite certain that the attack of
Mosquito as it appeared this year in the
Dam-Dim district of the Duars could
hardly have been worse, several gardens
in the north-west corner of the district
becoming practically closed towards the
end of July and in August. On visiting
these gardens in August it was found
that manufacture had come practically
to a standstill, leaf only being available
from a few acres of tea. ‘‘ Gray blight ”
in the case of oneor two estates was
also greatly responsible for the closing
of those gardens, and ‘‘ Red Spider” had
helped in the first instance to weaken
the bushes.
The greater area of tea in that part
of the district is planted with a low jat
bush, which, asis well-known, is much
favoured and first attacked by the
blight. Those portions planted with the
indigenous and better jats were last at-
tacked, andin some instances blocks
have been left almost entirely free from
attack, although situated in the centre
of the affected area. This, without
doubt, points to the advisability of gradu-
ally uprooting the poor jat hybrid
bushes and by replanting with high-
class materials. :
EFFECT OF SCARCITY OF LABOUR.
The scarcity of labour in that part of
the district did not permit of * thinning
out” the bushes at the pruning season,
and itcan, therefore, be easily under-
stood, when the nature of the growth of
China hybrid and low jat bushes is con-
sidered, that the mosquitoes had a sure
place of refuge in the heart of the
bushes where very little could get at
them to destroy them. The _ iusects
sheltering in such a place would be en-
tirely protected from wind and rain.
Storms, which were this year of a very
mild nature, did not destory wholesale

the newly-hatched out bugs as would
have been the case in seasonable weather,
and if the bushes had been thinned
of some of their branches and useless
twigs.
It was particularly noticeable on one
of the gardens in the district where
some replanting had been done with
high-class tea that the young plants
were practically untouched by the
mosquito, although the block was right
in the centre of the block with the
blight, and to all appearances closed for
the season.
There seemed to be no reason why
these young plants should not have been
attacked, even toa small degree, as the
mosquitoes must have been starving on
the surrounding tea, but the fact that the
replanted area (10 to 15 acres?) was not
attacked helps to confirm what has been
written in the above paragraph, namely,
that the bushes on the replanted area,
although showing plenty of foliage and
offering food for apparently starving in-
sects, had—first, no unnecessary wood
about them,and second, no cluster of
closely growing stems near to the ground
like the surrounding poorer jat tea, thus
allowing the passage of light and air
through their whole system of branhces.
No immature mosquito can live on a
bush under these circumstances, as
wind and heavy rain alone would des-
troy them.
This isin support of the suggestion
that those gardens subject to attack by
Mosquito blight, should, in the first
instance, do special careful ‘‘ thinning
out” at the pruning season in order that
the severer storms of wind and rain may
kill off the greater number of young
freshly-hatched-out mosquitoes and en-
able spraying with Kerosine Emulsion
and the catching of the insects by coolies
to be carried out more effectively.
Tur Use oF KEROSINE EMULSION.
This brings me to the matter of spray-
ing with Kerosine Emulsion. Up to the
present no better remedy than this, to-
gether with the collecting of the insect
by hand, has been found,; and it is my
opinion that it will be along time before
a better remedy will be discovered ; but
at the same time I do not think spray-
ing with Kerosine Emulsion has, on any
garden, been carried out ina thorough
and proper manner. Alsolam perfect-
ly sure that there are many gardens
which have spent thousands of rupees
every year in spraying with Kerosine
Emulsion without realising any appreci-
able benefit from the process. When
the habits of the tea mosquito, as given
(FEBRUARY, 1909.
below, are taken into consideration, I
think this will be brought home to many,
and the following may be of use in the
future treatment of the pest.
The general custom cf insects, on
being disturbed, is to retire to places of
safety, and this is particularly the case
with the tea mosquito. Where the mos-
quito occurs, so long as the bushes are
not thoroughly cleaned out at the time
of pruning, the difficulty of eradicating
it will be realised. In spraying, no soon-
er does the spray touch tke bush than
the insects either fall to the ground or
retire into the heart of the bush, where,
according to the way in which spraying
has been done inthe past, the insecti-
cide does not reach all of them. Every-
thing, therefore, depends upon the
manner in which spraying is conducted,
and, provided that a thorough cleaning-
out of the bushes has been carried out
in pruning, the emulsion will be able to
reach every part of the bushif applied
as now suggested. Itis not sufficient to
only spray the top and sides of a bush,
it must be thoroughly saturated with
the solution—the leaves, both upper
and lower sides, the stems, the soil and
“Jabra” at the foot; and the nozzle of
the sprayer should be placed right in-
side the bush, the spray being directed ~
upwards. The bushes cannot be too
much _ saturated. It is so important
that the upper side of the leaves should
be spraycd upon more than a very little,
because each leaf acting as a drain, the
liquid runs off one on to the next below,
and so on till it reaches the ground
round the outside of the bush. This is
almost an entire waste of material, as
the insects have by this time left the
surface of the bush and will be found in
the centre of it or at the collar in the
“Jabra” at the foot. The young flush
must, of course, receive the spray, and
that thoroughly.
WHEN TO SPRAY THE BUSHES.
Better results will be obtained if the
spraying is conducted during the heat
of the day, when the insects, both im-
mature and adult, are protecting them-
selves from the sun, inside the bushes,
and it goes without saying, of course,
that the freer a garden is of jungle at the
collar of the bushes the better will be
the effects of spraying.
To thoroughly saturate the bushes and
the “Jabra” atthe foot of them with
the mixture, in the manner. above sug-
gested, the cost of spraying per acre will
become rather more expensive than for-
merly, but this can partly be remedied
by adding more water to the mixture,
Frprvary, 1909]
which atthe same time will be a wise
procedure owing to there being a certain
amount of risk in burning the bushes
by saturating them with the liquid
atits usual strength. Further, if this
thorough style of spraying be carried
out, I think it willbe found that very
much less money will be required for
collecting the insects by hand.
This manner of spraying should be
done at least twice in the year if not
more frequently, and if one application is
not found sufficient—at the usual time
after pruning when the bushes are first
breaking out, and again, if one necessary,
about one month afterwards. So soon
as the insects are noticed to be feeding
and are about in any numbers, then is
the time to spray thoroughly without
sparing the liquid.
AN IMPORTANT POINT.
An important point to observe in deal-
ing with an epidemic of this kind is to
thoroughly treat the whole of the
affected area in the space of afew days,
as the quicker the “ round” ofthe garden
is made, the more thorough check will
it be to the deposition of eggs.
In the life-history of the Tea Mos-
quito it may not be known that the
feeding period of an individual lasts
for 2} months.
Without taking into consideration
the hybernating period of the insect
during the cold weather months, mature
or winged individuals kept in captivity
in the Insectarium at Kanny-Koory,
lived for 62 days, and if we add to this
the period spent in the immature or
larval form, which is roughly 10 days,
we find, at the height of the season, a
single insect lives for quite two-and-a-
half months. Add to this the fact that
an insect will make as many as 125-150
punctures in the leaves every 24 hours,
and the damage done to the bush can be
imagined.—The World, December, 1908.
DEVELOPMENT Or DISHASE-
RESISTANT VARIETIES
OF PLANTS.
By H.S. Jackson, Newark, Del,
[Given before the Massachusetts Horti-
cultural Society, March 14, 1908. |
While the subject which I have
selected may not be of special local
interest, I believe it to be of sufficient
general interest to merit a discussion
before any body of men interested in
any branch of agricultural science. In
the entire discussion of the development
of disease-resistant varieties, | may not

mention any special crops which are of
particular interest to Massachusetts
Horticulturists, for this phase of plant
breeding is not sufficiently developed as
yet toenable us to direct the grower
how to proceed to obtain results, except
with very few crops. The study of the
development, by man, of disease resist-
ance in plants is yetinits infancy.
propose to discuss the subject in general,
and to give a review of what has already
been accomplished by horticulturists and
plant-breeders in developing plants
resistant to specific diseases.
We must first get a definite idea of
what is meant by disease resistance in
plants. We must distinguish it from
hardiness. Hardiness is a general term.
A hardy variety, as generally considered,
is merely one that is less susceptible to
cutting frosts, drought, or extreme
changes in temperature; in short, one
that is capable of withstanding adverse
climatic conditions in a state of health.
A disease-resistant variety for our
present purpose may be defined as one
that shows resistance to the attack of a
specific disease due to a_ specific
organism.
In this age of intensive agriculture,
with our advanced and _ increasing
knowledge of the principles of culture
and fertilization of all sorts of agri-
cultural crops, the question of the health
of the plant is recognized as one of
paramount importance. We know that
under certain conditions, if we give our
plants the proper food and the proper
cultivation, we may expect a reasonably
healthy crop. Neglect these factors and
we know that we may expect an un-
healthy crop. We know that soil, plant-
food culture and weather conditions all
have their influence on the health of
plants.
We have come to learn, however, that
we cannot control many specific diseases
by cultural methods. We must resort
to spraying and seed or soil treatment
of various kinds. We know that we can
control apple, scab bitter rot of apples,
black rot of grape, and many _ other
similar diseases with Bordeaux Mixture.
We have come to realize that spraying
of certain crops is a necessity to success-
ful culture. The successful apple grower
sprays as faithfully as he prunes. The
successful potato grower, in sections
where late blight of potatoes is pre-
valent, sprays as_ regularly as _ he
cultivates, and is always assured of a
crop. The farmer who wishes a crop of
oats free from smut knows that he may
obtain such a crop by proper treatment
of seed before planting. The market
gardener who grows cabbage with the
Plant Sanitation.
best success knows that he must treat his
cabbage seed with formalin or corrosive
sublimate as a precaution against the
introduction of the bacterial rot.
There are a host of diseases which
might be mentioned for which some
specific treatment is in common practice.
Why then is it necessary for us to
have resistant varieties? Spraying is a
nuisance at best, and any man who has
had any actual spraying to do would
ladly eliminate this not inconsiderable
item of labour and expense. The second
reason is that, while spraying may be
profitable for the large grower, parti-
cularly the man who makes a speciality
of some one crop, it frequently is not
profitable for the small grower. The
man who grows afew apple trees, a few
acres of potatoes, tomatoes, cucumbers
and other vegetables in proportion,
frequently has to give up the cultivation
of any crop that is repeatedly attacked
by aserious disease. Spraying frequent-
ly is not profitable for men who carry
on diversified farming. I do not wish to
be misunderstood in this connection.
When the mere item of added expense
of materials and labour necessary to the
spraying alone is considered, we will
nd that spraying is profitable in most
cases even for the small grower.
The labour question, however, adds
another factor. When it is possible for
the small grower or the man who carries
on diversified farming to obtain addi-
tional labour of the right sort at any
time, he can spray his various crops with
profit, but when labouris limited and the
grower must depend on his steady labour
todo the spraying, he will usually find
that to carry on the work properly other
important things must be neglected.
Spraying must be done at the right time,
or itis of no value. The third reason is
that there are many diseases which
experimentally can be controlled, but
not profitably. Asan example, we may
mention the rust of wheat and many
other diseases of fieldcrops. The fourth
reason is that certain very serious
diseases have never been satisfactorily
controlled even by experiments. To
this class belong such diseases as peach
yellows, crown gall, and various soil rots
and wilts.
plants belong to this class.
METHODS.
In order to develop varieties resistant
to disease, several methods of work are
open to the investigator :—
(a) Selection of individuals.
(6) Selection of varieties.
(c) Hybridization followed by selec:
tion of varieties and individuals,
Most bacterial diseases of |
166 (FEBRUARY, 1909,
SELECTION OF INDIVIDUALS.
Every grower of plants has doubtless
observed that in a field of a crop suffer-
ing from an epidemic disease, certain
individual plants may show more or less
resistance to the disease. By selecting
seed from such plants we would expect,
if the resistance is an actual one, to have
offspring which would inherit the
character of resistance. By repeated
selection through several generations,
always saving seed from the most
healthy plants, we would expect to
gradually develop a variety or strain
much more resistant than ordinary one.
This has been practically tested in a
number of cases and found to be success-
ful. Mr. P. K. Blynn, of the Colorado
Experiment Station, has obtained most
satisfactory results by this method in
selecting a strain of cantaloupe known
as the pollock strain, resistant to the
very serious leaf spot disease due to
Macrosporium cucumerinum.
SELECTION OF VARIETIXS.
In order to obtain results by this
method, all the vatieties of a crop obtain-
able are grown on infested ground in
order to study their relative resistance
to disease. Experimenting in this way
some variety may prove exceedingly
resistant to the disease in question and
further work rendered unnecessary
except to keep the variety pure. Usu-
ally, however, all commercial varieties
will be more or less susceptible. If such
is the case, then the varieties least sus-
ceptible must be studied further and
selection of individuals proceed as in
the first method. 1 believe that the
most certain and best results are to be
obtained by combining the first method
with the second. That is, select the
most promising varieties with which to
practise individual selection.
HYBRIDIZATION.
In case no varieties give promise of
resistance, hybridization, or crossing,
may give satisfactory results. It fre-
quently happens that wild species which
may be worthless commercially, but
closely related to cultivated forms,
show marked resistance to diseases which
seriously attack the latter. Sometimes
we may havea variety which is worth-
less commercially, but which is known
to be strongly resistant. If such a
resistant species or variety be crossed
with a profitable commercial variety,
and a close study of the resulting off-
spring be made, some desirable new
variety thus produced may show marked
resistance. A notable example of this
method of procedure is the work of
Mr. W. A. Orton with water melons,
iis: aie BY at OURS as a Sb
FEBRUARY, 1909.1
Water-melons in the South are seriously
attacked by a soil disease (Neocosmos-
pora), which it has been impossible to
combat satisfactorily. Mr. Orton first
made a study of all varieties of water-
lemons and related plants obtainable,
and found that all commercial varieties
were almost equally susceptible. He
found, however, that a form of citron
(hard fleshed melon) was very resistant,
but worthless commercially. He crossed
this with commercially desirable varie-
ties. The seed resulting from this
cross, when planted the next year, re-
vealed the fact that he had obtained
about a thousand new varieties, most of
which were either worthless commer-
cially or non-resistant. He selected a
few of the most promising of these for
further study, and found that he had
one variety commercially desirable,
profitable, and strongly resistant,
WHAT HAS BEEN DONE.
Let us see what has been accomplished
toward obtaining practical results in the
breeding or selection of disease-proof
varieties. I will speak briefly of some
of the most notable results obtained in
this country or applied to American con-
ditions. It is not my purpose to review
the observations (and they are many)
on resistant varieties of vegetable or
fruits that are in common use, but to
confine myself to a discussion of the
outcome of definite efforts to obtain
varieties resistant to specific diseases.
WHEAT.
We will agree that to spray a wheat
field for rust would be out of the ques-
tion from a practical standpoint, even
though such treatment might rid the
crop of the disease. It is evident that
in sections where wheat rust is especially
prevalent, disease-resistant varieties of
wheat would be of special value. Inves-
tigations have been made in Kurope,
Australia, and the United States for
the purpose of obtaining rust-resisting
wheats. More or less success has been
obtained by all investigators, Carlton,
working in this country, has made a
study of all available varieties from all
countries and has found that certain
varieties of the Durum wheats are most
resistant to the black stem rust. In
this connection the recent work of R. H.
Biffen on the hybridization of wheats
bids fair to have a far-reaching influence
on future work in developing immune
varieties. Hefound that susceptibility
and immunity in certain varieties of
wheats are definite Mendelian charac-
ters, the former being the dominant one.
CLOVER.
Messrs. Bain and Essary of the Ten-
nessee Hxperiment Station have con-
167
Plant Samtation
ducted experiments in selecting and
developing a variety of red clover resist-
ant to a new fungus disease belonging
to the anthranoses, that has for several
years threatened the cultivation of red
clover in Tennessee and the South.
They have practised selecting seed from
individual plants which survived in a
field very seriously attacked by the
disease and have obtained very satis-
factory results.
Cow PEA.
This plant suffers in the South from
two serious troubles, a wilt disease and
a nematode root gall. Varieties have
been studied and the Little Iron cow-
pea has been found to resist the attack
of both these diseases.
POTATORS.
Various potatoes resistant to the late
blight have been known for many years
in Europe. Recently the study and
selection of resisting varieties have
secured considerable attention in this
country. Jones and Stuart, working at
the Vermont Experiment Station, have
had very favourable results in selecting
varieties resitant to this trouble. The
work on potatoes resistant to this
disease has been largely a study of
varieties. Itis still in progress, In con-
nection with the work with late blight
attention has been paid to sorts resis-
tant to scab. The Ohio and other Sta-
tions have had marked results in select-
ing varieties and individuals resistant
to the early blight (Alternaria) which is
not easily controlled by spraying.
TOBACCO.
This crop is attacked in Connecticut
by a serious wilt disease. By selecting
seeds from individuals which have sur-
vived in a field nearly totally destroyed
by the disease, Shamel and Cobey have
succeeded in developing resistant strains.
A similar disease in North Carolina has
been investigated in the same way with
very favourable results.
This plant is also attacked by
Nematode worms, which cause gall-like
swellings on the roots. Experiments
are now underway by officials of the
U.S. Department of Agriculture for the
selection of varieties resistant to this
trouble.
COTTON.
Very satisfactory results have been
secured in selecting varieties resistant to
the wilt of cotton in the South. The
work has been carried on by W. A.
Orton of the Department of Agriculture.
He has found that several varieties of
Egyptian cotton, as well as one Upland
cotton, give great promise of resistance.
Plant Sanitation.
He suggests crossing the different resis-
tant sorts, especially resistant varieties
of different races, with the hope of
obtaining varieties which will combine
the good qualities of both races.
Mr. Orton’s investigation of cotton
resistant to the wilt fungus revealed
a very important fact. He found
that even with the most _ resistant
sort grown on infected land, infection
occurred in the rootlets, but the fungus
was notable to gain entrance to the
main root system, and therefore could
not spread in the plant. The resistance,
then, in cotton to the wilt fungus is not
caused by some peculiarity of the root
which prevent the entrance of the
fungus into the tissue, but to some
undetermined character which prevents
the spread of the fungus toany extent
after it has gained entrance to the
tissue.
W ATER-MELON.
\n account has already been given of
the success of Mr. Orton in obtaining a
wilt-resistant variety of the water-melon
by hybridization with the citron.
CANTALOUPE OR MUSK-MELON.
The work, previously mentioned, of
Mr. P. K. Blynn, special agent of the
Colorado Station, in developing the
Pollock strain of the cantaloupe resistant
to leaf spot disease due to Macrosporium
is especially notable, as it is, perhaps,
the most successful attempt yet made in
this country to develop a variety resis-
tant to a leaf parasite. The strain is a
result of careful selection of seed from
resistant vines.
ASPARAGUS.
It is well known that the Palmetto
variety of asparagus is especially resist-
ant to rust. It is, however, not a
desirable variety for canning. In Cali-
fornia, R. E. Smith of the State Experi-
ment Station, is engaged in developing
a variety which will combine rust
resistance with the qualities desired
by canners found in the Conover’s
Colossal.
VIOLET.
Violets grown in greenhouses are
especially subject toa leaf spot disease
known as Alternaria viale. Itis known
among violet growers that the Lady
Hume Campbell variety is the most
naturally resistant variety in culti-
vation. This natural resistant has been
greatly increased by carefully selecting
the most resistant plants from which to
propagate.
FRUITS.
Little work has been attempted to de-
velop disease-resistant varieties among
168
(FEBRUARY, 1909.
the fruits. As Ihave previously stated,
the development of disease resistance is
a comparatively new undertaking for
plant-breeders. That is,it has beena
relatively short time since horticul-
turists and plant-breeders have under-
taken, with a definite idea in view, to
develop varieties resistant to specific
diseases. Perhaps this is why little
work has been accomplished among the
fruits. Obviously it would take a longer
period to obtain results in developing
varieties of perennials than annuals, and
the plant-breeder will naturally select
for study those problems which give
promise of solution in the shortest time.
It is, however, a matter of common
observation that some varieties of cur
tree fruits are more resistant to certain
of their maladies than others. For
example, in Delware, it is known that
among apple varieties the Lily of Kent
is above all others most resistant to scab
and bitter rot, while the Jonathan is
especially susceptible to rot. The whole
Winesap group is said to be relatively
resistant to rot but susceptible to seab,
while the York Imperial is resistant to
scab. Among pears the Keiffer is known
to be resistant to fire blight, while the
Bartlett and others are very susceptible.
A host of such observations might be
cited to show that among our tree fruits |
there is varietal variation as regards
resistance to disease.
There are some diseases of tree fruits
which are especially troublesome and
impossible to combat satisfactorily, for
which it would be highly desirable to
have resistant varieties. I refer parti-
cularly to the peach yellows. The
observations of Professor E. W, Morse.
reported in the Bulletin of the Bussey
Institution, indicate that individual
peach trees from which to ‘propagate
may be found which are resistant to
yellows. Since no satisfactory method
has ever been tound to combat. this
dread disease, the study of the problem
of prevention from this standpoint is
highly desirable.
Another disease of great importance
is the crown gall of raspberry and black-
berry. This is a very serious trouble
in infested districts. In Sussex County,
Delware, the raspberry industry, once
very large, has been practically wiped
out by this trouble. Since the organisms
of the disease are retained in the soil
and attack the roots or crown only, no
preventative measures are practicable.
It seems highly desirable to attack the
problem of the treatment of this disease
by the selection .or breeding of disease-
resistant varieties. ;

In view of the popularity attained
amongst cultivators throughout India

PIG FARMING IN BRITISH EAST
AFRICA.
A REVIEW.
We have to acknowledge the receipt
of a nicely got up booklet entitled ‘‘ Pig
Breeding and Feeding in East Africa”
by J. EH. Prossor, adviser in Swine Hus-
bandry and Bacon-curing to the Uplands
of Hast Africa Syndicate, who has
devoted his life to this branch of farm-
ing. The author, in transmitting the
work, writes:—‘‘I have been looking
into the figures giving the quantity of
bacon imported into India—over £70,000
annually—and it has struck me that
a country like India should grow its
own pork as the heat suits pigs in this
country (British Hast Africa), and, now
that refrigeration has been brought to
its present standing, there is no diffi-
culty in curing in any climate or at
any temperature. I shall be glad to
exchange any information with you.”
Pig rearing has, so far as we know,
never been taken up as a serious busi-
ness in the Island; but, judging from
a perusal of Mv. Prossov’s work, there
would seem to be no reason whatever
why it should not prove a successful
venture.
No systematic farmer in any country is
without pigs. In Ireland the pig is look-
ed upon as ‘‘ the gentleman who pays the
rent” ;in Denmark as ‘‘the Savings bank.”
In America, pigs are found to pay when
other animals do not, proving there and
elsewhere ‘‘the farmers’ friend.” As
regards East Africa, after a careful
study of the conditions, Mr. Prossor
says: ‘‘ITam certain that once the set-
tlers knew that they have a regular
and sure market, provided they breed
and feed the right sort of pig, they will
find that there is no class of stock that
will pay them better and turn over
the cost ina shorter time.” And in his
book Mr. Prossor proceeds tc instruct
the reader on all matters connected
with selection, feeding, &c, so that one
cannot go far wrong if he carefully
studies the facts and figures in the
manual referred to. In Ceylon there
would appear to be as great facilities
in the matter of food, &c., as in the
colony regarding which the expert re-
ports. We shall be glad to give any
information on this subject that read-
ers who are interested in it may desire

SCIENTIFIC AGRICULTURE.
ON PLOUGHING.
Weare all familiar with the phrase,
‘A little farm well tilled.” That short
sentence describes the modest wish of
everyone who launches intoan agricul-
tural career. Having got the ‘‘little
farm,” the wish expands into a ‘big
farm,” and, by keeping the “ little farm”
well tilled the “big farm” may become
an accomplished fact. Tillage in agri-
culture isa most important operation,
its object being, of course, to bring the
ground into that state of tilth best
suited to the growth of grass and crops.
In order to obtain this tilth, the employ-
ment of many kinds of implements are
required, and the first of theseis the
plough. Itis not now regarded as the
most important, because the cultivators,
grubbers, disc harrows, and similar im-
plements reduce the ground toa proper
condition fora seed bed, even if the
ploughing has been badly done. There
can be no doubt, however, that the
plough isa very important machine in
agriculture, and must continue to beso
till the end of time. It is the most
ancient implement known, but within
the last century it has been improved
very much indeed—in fact, there are
few machines which have been more
altered in its appearance and in its work.
Wood has been replaced by iron; steel
has taken the place of iron ; and mechan-
ical laws have been applied to make
the implement easier to pull and more
effective in its work. As the years go
on, new principles are being applied, and
there are now quite a number of
different kinds of ploughs on the market
and in general use. There are the ordi-
nary single and double furrow ploughs
(swing ploughs are rarely seen now-
a-days), digging ploughs, subsoil ploughs,
gang and stump-jumping ploughs, one-
way or hillside ploughs, multiple
ploughs, and, last of all, disc ploughs.
Some of these, as their name denote, are
special-purpose ploughs, and with these
there is no necessity to deal in the
present article.
Single-furrow ploughs are not used
except on small holdings and in gardens.
They are now fitted with wheels, which
keep them steady and at a uniform
depth. Swing ploughs are balanced by
the ploughmen, and require more skill
in their management than wheeled
ploughs. Single-furrow ploughs are
often used for opening lands or striking
out, and also for finishing. They are
also used for such work as potato-plant-.
ing ae ough the double-furrow is also
used.
The double-furrow plough has for
long time been the principal kind o
plough used in New Zealand. It is now
in some districts being superseded by
the treble-furrow, which is in reality a
double-furrow with another beam and
mould-board attached. The principle is
exactly thesame. The idea of the extra
furrow is to give the larger teams, which
must be used in cultivating and drilling,
sufficient work todo when ploughing.
It is not so long ago that three and four
horse teams were in vogue. Nowa days
the five and six horse team is in
more general use, because of the extra
strength required to haul up-to-date
cultivators, disc harrows, and drills.
Then, again, dig ger and disc ploughs are
being used very largely, and _ these
demand larger teams than the old four
horse team.
A plough is, in reality, a combiration
of instruments fastened toa beam. The
most important of these instruments are
the coulter or skeith, the share or sock, ~
the mould-board or breast, and the
bridle, Other parts are added, accord-
ing to the kind of plough desired, but
usually there is a lever and a steering-
rod. It is not necessary for me, I
suppose, to describe the function of each
of these parts. Before describing the
different kinds of work done by several
kinds of ploughs and the uses of each, I
will give a few of the terms used in
ploughing.
There are two principal methods of
ploughing—viz., in landsand round-and-
round. The former method is used on
flat land and on undulating downs,
while the latter is used in steep localities.
With practice, a perfectly straight
furrow may be maintained, and witha
little patience almost ary plough may
be set to cut and throw all its furrows
alike and evenly. The turning-voints
at the ends of the ‘‘lands” are called
‘“‘headlands,” and it is important that
youths starting to plough should be
taught to keep their furrows square with
the headland, and the headlands them-
selves the same width right through. A
plough cannot do good work uuless it is
kept in good order, and every ploughman
should know how to keep his plough
wheels packed and his skeiths running
true. For skeiths, I find the ‘‘cones”
the best kind of axle to use. Skeiths

should not be used among stones, nor
should they be used in frosty weather,
as they are liable to get damaged very
seriously. The ordinary double and
treble furrow is mostly useful for
loughing in the autumn, when it has to
Be fallow through the winter for turnips
or oats in the spring. Lea ploughed for
wheat should be turned the round-and-
round method. In this case it is a lazy
man’s method. It continually moves
the land towards the fences, while
denuding the finish in the middle of the
paddocks of soil. This applies also, of
course, to ploughing steep country
round-and-round, but it is unavoidable
in this instance. By ploughing in lands,
good drainage may be effected ; the land
ean be effectually cross-ploughed, and
the land can be kept fairly even and
level by altering the place for striking
out.and finishing. The crown of the
land is the high ridge formed by marking
out, or striking out, as it is usually
ealled. This marking out is called
“feeding.” The open furrow between
the lands is called the ‘‘finish.” The
furrows may be either gathered towards
the crown of the land, or they may be
scattered till an open furrow or finish
results. In gathering, the team pulls to
the right; ‘‘gee-back” is the command
given by the ploughmen. In scattering,
the horse turns to the left, or ‘come
here,” as their driver would say. There
are also several kinds of furrows, chief
among which is the rectangular furrow,
made by a fat-cutting share and an
upright coulter or skeith; a high-cut
furrow, obtained by using a share raised
on the wing side, and a skeith or coulter,
cutting a furrow at an angle. The
digger plough has a furrow peculiarly
its own, which I will attempt to describe
later on.
I have said that the single-furrow
plough is very frequently used for
marking out and finishing lands. This
operation may, however, be done equally
well with a double or treble furrow
plough; and there are very few who
now trouble with a single furrow for
marking out. Some prefer three horses
for striking out witha double furrow,
but it may be done, with practice, with
any team. Now that the seed is usually
drilled instead of being sown broadcast
on the furrow, there is not somuch used
from the utility point of view for
straight ploughing. Ploughing matches
are going out of fashion, except in parts
of South Canterbury and Southland, but
it would be wellif our agricultural and
pastoral societies took the matter up.
Stubbles ploughed from autumn oats

kinds of multiple ploughs now being
used. These multiple ploughs are princi-
pally useful for stubble work, and for
turning over land out of turnips for
either rape, grass, or oats. Oats are
shallow-rooted, and therefore the digger
may be reserved for the deeper-rooted
wheat. Sometimes a mistake is made by
ploughing too deeply for oats and for
turnips. dry season comes, and the
roots fail to reach the subsoil, Had the
land been ploughed fairly shallow, say
three or four inches, the roots would
have reached the stored-up moisture, and
would have givena good crop. Moreover
being shallow rooted, they get the
benefit of animal droppings and decaying
vegetation when the furrow is fairly
shallow, and also of the work of soil
bacteria which are always more active
se the surface than lower down in the
soil.
I have mentioned digger ploughs
several times, and will now endeavour
to describe them and their functions.
They are daily coming into more extend-
ed use, and in parts of Canterbury and
Southland are thought very highly of
indeed. Personally, I may say that some
ten years ago I tried them, but was
disappointed at the result, and gave
them up. Some half-dozen years ago we
had some very wet seasons, and I found
that the digger would work where the
ordinary plough would _ not. They left
the ground in good condition for sowing
grain on, and the crops did well. The
secret of the whole matter was that the
ploughs were being worked at too greata
depth when they were previously being
used. The breat or mould-board has a
kind of shin on it which acts as a coulter,
A skim coulter takes the place of the
usual skeith or long coulter. This skim
coulter assists in cutting the furrow,
but most of the vertical cutting is done
by the shin on the mould-board. The
horizontal cutting isdone bya broad
share, which forms the forepart of the
mould-board. The shape of the mould-
board is different to that on the plain
double-furrow. It is much shorter, is
slightly disked, and then takes an out-
side curve. The earth is thrown out-
wards and over, and is not compressed
or packed. It is left in much the same
condition as it would be if dug witha
spade. The land _ lies loosely, and frost
can get into it. The water runs through
it, and there is no solid furrow to be
worked down. As I have already in-
dicated, the digger can be worked in
stiff, clay soils in wet weathe1, when
the plain plough would have to remain
idle. It does a great amount of after-
cultivation. A stroke of the tines or
discs before the drill, and a couple of
Scientific Agriculture
where in other cases scarifiers and
rollers would have to be used. The
digger buries grass and weeds deeply
down, so that they do not get a chance
to grow through the furrows. More-
over, the vegetation gets rotten about
the time the ear of cornis filling, and
helps materially to form food for the
plant at a time when it requires it.
There is, as already stated, a danger of
turning up too much sour land, so that
the seed does not grow away quickly.
This must, of course, be guarded against.
The plough will plough no deeper than
where itis set. I know of people who
quickly discard the digger because they
cannot make them do good work. The
fault is, very often, that an attempt is
being made toturn overa furrow too
wide for the depth. The resultis that
the desired crumbling, feathery state of
the land isnot attained. As a rule,
people do not, on clay lands, desire to
plough deeper than 6 or 7_ inches.
Roughly speaking, 1 inch of depth re-
quires 2 inches of width. Thus a furrow
6 inches deep should not have a greater
width than 12inches. A furrow 6 inches
by 15 inches would bea failure, in my
experience. In marking out, the front
wheel should be lowered in order that
the front plough shall not plough too
deeply, and throw up too higha ridge.
In finishing, much the same method is
adopted as with an ordinary plough.
It is well to repeat that the first time of
ploughing must not be too deep. The
soil on the top after ploughing is all
brought up from the bottom of the
furrow. A paddock may easily be
spoiled for a year or two because of too
deep ploughing with the digger. They
are often spoken of as horse-killers, but,
as a matter of fact, they are not more so
than an ordinary plough. They certainly
require more strength, but they will
turn over four acres a day, where an
ordinary plough will only do between
3and 33 acres in the day. In ground
where they have never been used before,
the work is harder than on land where
they are frequently used, because there
is a certain amount of subsoil to be
turned up for the first time. In ordinary
cases five horses will work them as
easily as four will work a plain plough,
and, asI have said, they will do from
half acre to one acre more work. The
mould-board is shorter, but there is less
friction, because it hasonly to clear its
way, whereas a plain plough has to be
dragged through the ground like a
wedge.

kinds of work on certain kinds of land.
For cross-ploughing in autumn they do
good work, breaking up the ground
thoroughly so that but little after-work
is needed to make a good seed bed.
They do well on stubbles in the autumn,
and get overalot of ground in aday.
They are made somewhat on the principle
of the disc harrow, and require more
power than an ordinary plough. If they
are set narrow, and the ground is level,
four horses will make them on stubble,
turnip land, or fallow, and five on lea
land. Generally speaking, however,
they require five horses for the former
kind of land and six on the latter,
especially if the ground is hilly. They
ave not suitable for turnip land which
has been tramped and poached by stock
in the winter, as they leave the ground
too lumpy and rough. It is on _ the
twitchy land that the disc plough is
most serviceable. In fact, it will throw
about land infested with couch, yarrow,
and other plants with creeping roots in
splendid style, where a plain furrow
plough will scracely touch it. Paddocks
which have been given up as unworkable,
by reason of a mat of twitch or couch,
have been brought into eultivation
again by thedisc plough. It throws
the furrows in the air, and leaves them
lying uy to the sun and weather in such
a manner that the plants are half-killed
before after-cultivation is started upon.
Moreover, the furrow, instead of being
packed hard, so that no disc harrow or
cultivator can touch it, is left so that
these implements can smash them about
splendidly. Some farmers break up
twitchy land with the ordinary plough,
and then put the disc plough on to
cross-plough, with very satisfactory
results, In my opinion, the disc plough
is an implement that materially reduces
the fear that twitch and couch, and such
like weeds will utimatelv get possession
of our arable lands,—A NEw ZEALAND

THE DUST MULCH.
Direct evaporation from the soil can
be checked by keeping the upper 2 or
3 inches of the surface well cultivated,
soas to form a dust blanket, or dust
mulch. When the ground is kept
covered with a thick layer of dry, loose
soil, evaporation is slight, but when the
soil surface is not kept dry and locse,
evaporation goes on very rapidly. The
tools required for maintaining the dust
mulch are a common harrow, a weeder,
and various forms of cultivators. The

fact that the soilin the vicinity of San
Antonio is heavy, together with the
comparative rarity otf high winds,
makes it possible to maintain an effec-
tive dust mulch and to accumulate in
the soil enough moisture to carry ona
crop to maturity even if little rain falls
during its growth.
_ After the dust mulch has been des-
troyed by a rain, evaporation from the
supply of water in the soil begins as
soon as the rain ceases, and in cases
where the weather immediately follow-
ing the rain is hot and windy this
loss of moisture becomes exceedingly
great. On the heavy soils of San Anto-
nio a light rain, as for instance 0°1 to 0°4
inch, reduces rather than increases the
173
Scientific Agriculture.
total amount of soil water. This is
apparently due to the fact that such
light rains are only sufficient to establish
capillary connection between the sur-
face soil and the moisture in the lower
soil, and before the surface is dry
enough to permit cultivation some of
the moisture has been drawn from the
supply below and dissipated into the
air. A rain of less than 0:1 inch is
usually sufficient to establish such capil-
lary connection, and is therefore harm-
less. Even a heavy rain, unless followed
immediately by cultivation to renew
the dust mulch, may result in a reduc-
tion rather than in an increase of the
amount of soil moisture. Such a case
is illustrated by Table 1.

MANURE,
TILLAGE AS A MANURE.
APPLICATION TO COCONUT CULTIVATION.
Is it more profitable to use famyard
manure—i.e., cattle and other dung
mixed with straw, waste herbage, and
refuse properly decomposed in a pit—
than artificial is a question that should be
of great interest to all planters and agri-
culturists. Artificial or special manures
contain but few of the constituents re-
quired for plant nutrition, and are
applied to those crops which require
more of a certain ingredient than the soil
contains. Farmyard manure on _ the
other hand is a general manure, con-
taining all the constituents required
by plant life. Artificial manures are
much quicker in action than farmyard,
and are an essential auxilary to general
manures. A general manure may be
used year after year on the same land,
but artificials, if used exclusively, would

ultimately exhaust the soil. | The
minimum of any one essential ingre-
dient rules the crop. Jt does not matter
how great a quantity of the other con-
stituents may be present, good crops
cannot be obtained if one substance is
deficient. When this is the case a
special manure produces as good effect
as a manure containing everything
necessary to plant growth. The world’s
experience has proved that it is not
advisable to continuously apply_ farm-
yard manure. If a field was dressed
every year with farmyard manure,
after a timethere would bein the soil
constituents more than are necessary,
and a large store of fertility would have
accumulated. And though the field
may be said to be in a high state of
fertility crops will not prove as _satis-
factory as might be expected. This is
because alarge quantity of food is
LYING IN A DORMANT CONDITION
in which state plants cannot assimilate
it. In such cases a special manure
which would convert dormant material
into active matter suitable for plant
nutrition is valuable. Instances of the
above are sometimes seen in land in
high condition from previous manuring.
Asa rule an application of nitrate of
soda will cause the crop to grow and
bear vigorously, the plants making use
of the hitherto dormant matter. The
difference betweer the nitrogen in the
nitrate of soda and the nitrogen in
farmyard manure is that in the former it
is immediately available and is taken
up at once by the roots, whereas in farm-
yard manure the nitrogen is partly
locked up and is only made use of as
it becomes available. The effect of a
dressing of nitrate of soda is not seen
beyond the cropto which it is applied,
whereas the effects of a dressing of
framyard manure is seen for many
years after. Another thing which must
not be forgotten when comparing arti-
ficial with farmyard manure is the
mechanical effects produced by the
latter in the soil, artificial having no
such effects. By the fermentation of
farmyard manure in the soil its texture
becomes improved. Carbonic acid, the
most powerful disintegrator known,
is evolved, and helps to break up the
soil and release the stores of food it
contains, much more effectively than
any process of ploughing and cultiva-
tion.
TILLAGE OF MANURE.
There is, as a rule, a large quantity of
undeveloped natural fertilisers in most
soils. If nature were not very conser-
vative the careless agriculturist would
rob the soil of its most valuable consti-
[FEBRUARY, 1909,
tuents faster than he does, either by
carrying plant food off, or allowing it
to leak or wash away. It is noticed that
organic matter, as soon as it ceases to
live, is revolved into its original ele-
ments, and that these elemerts in most
cases combine with bases—the phos-
phoric acid with lime, the potash with
silicates, and so on—and when combined,
they are often so securely locked up
and preserved that this plant food is
not available unless the cultivator does
something to help along the natural
processes. The cultivator has in most
cases taken from the land the plant-
food which is easily available, has often
robbed it of its humus, hence its mois-
ture-holding capacity. The crops then
suffer from two distinct causes, first a
lack of a full supply of available plant
tood, and second from lack of moisture,
Tillage makes the plant-food more avail-
able. To provide the moisture and not a
sufficent amount of available plant-food,
would be like giving a horse all the
water it requires, but not enough paddy
and grass.
NO ONE CAN FORETELL
how much cultivation will be necessary
to secure maximum crops. In some soils
the plant-food is extremely lazy, in other
soils it may be deficient rather than lazy.
The soil that contains an abundance of
dormant plant-food is more valuable
than that which contains asmall amount
of available food. In the case of annual
crops the reason why soluble plant-food
is frequently so beneficial is because the
plants when youtg cannot secure from
unaided soil sufficient nourishment, and
they become dwarfed, and never entirely
recover. Ifa sufficient supply of plant
food has not been provided for the
young plants by tillage, it is always well
to add available plant food which may
serve as a Starter. A young calf cannot
be well nourished on straw. }

CARAVONICGA COTTON AND ITS
SPONSORS.
INTERNATIONAL COTTON COMPANYS OPERATIONS.
Ittis avcurious coincidence that ou the heels
of Mr, Stewart McCall, who has just reported
on the prospects of cotton-growing for Ceylon,
should come—from Queensland—the well-known
inventor of Caravonica Cotton, Dr. David
Thomatis ; but: it is more curious still that
they should be meeting at Aden next week
and travelling thence to Kast Africa, by Ger-
man steamer. It remains to be seen whether
Mr. McCall will be persuaded as to the merits
of the bigger-yielding species, and get it taken
up in Nyasaland, rather than the Egyptian variety
which he at present favours. Dr. Thomatis
called on us on Jan. 15th on his passage through
by the N. L.;‘‘Roon” and surprised us by
what he told us of the way the hybrid cotton
he has bred has been taken up on the Conti-
nent. Himself coming of Scottish and Italian
percentage, he appears to have combined the
persistence of the one race with the ingenuity
of the other; and it has only been the work
of about five years to bring to perfection the
cotton, which—grown at his plantation at
Cairns—has already made his name famous.
It has been tried in South India; but—Dr.
Thomatis thinke—its failure there must have
been due to unseasonable planting or unsuit-
able rainfall. lu Queensland, he says, where

and of his unique work, the producer of Cara-

scale there; he would have been supported to
the tune of several millions sterling, had he been
allowed by the Australian Goverument to im-
port some thousands of Indian coolies for the
purposes of cotton-growing. But Australia—
against its own interests, as we hold, but yet in
favour of such colonies as Ceylon which feel

refused to allow black labour in for the enrich-

a fancy class of cotton, and too fine for ordi-
nary work, Much machinery in Lancashire has
been altered to suit Egyptian cotton, which is
finer than American; we wonder whether the
turn of Caravonica will similarly come later on
at the hub of the cotton-spinning world? On the
Continent, meanwhile, it has been widely taken
up; in France, the silky Caravonica is used for
making all the finer classes of cotton goods—
while another kind of ‘ woolly’ cotton, which Dr.
Thomatis has also bred, is widely used as a substi-
tute for wool. Butit is in Germany that the |
inventor has been received with open arms ;
and at Berlin, are to be found the headquarters
of the Syndicate, called the International Cotton °
Company (‘‘ Der Baumer Gesellschaft Caravoni-
ca’’) which has been formed in the past year.
The Company, comprising several Huropean
banks and leading Cotton men on the continent,
is designed to control and direct the produc-
tion of Caravonica cotton—through recognised
and approved landowners and agriculturists.
If has a capital of some £6,000,000 to £7,000,000
and willlend money at 3 per cent and provide
seed. The only restrictions are that no seed
must be sold or disposed of to any one out-
side the Company, though as to the disposal
of the cotton itself the Company makes ro
restriction. It is, however, willing to buy it—or
act as selling agents when desired. Asked how
the disposal of seed could be so controlled over
the wide field of operations proposed, Dr.
Thomatis said the Company would be dealing
with honest men, to whose interest it would be
not to dispose of the seed except as their credi-
tors (the Company) required. Dr, Thomatis is
Advising Director to the Company and_ while he
has left a Manager in charge of the plantations
(once his own) in North Queensland, he is now
enroute to Dar-es-Salaam, German East Africa,
to select land—either already occupied by set-
tlers, orto be occupied, to be cultivated with
the new product. Already, he says, some 750,000
acres are under preparation in the Soudan, to
grow it; while Kastern Cuba is the other (fourth)
large centre where its culture will be carried
on. The ‘‘ Fram,” the vessel from Norway of
Arctic exploring fame, has recently taken
and Magazine of the Ceylon Agricultural Society.
6u to 70 Norwegian families to settle in the last-
named country on chosen land expressly to
grow Caravonica. [The Berlin office telegraphic
address, t may be incidentally mentioned, is
composed of the first letters of the four offices
of the Company: Berlin, Alexandria, Cairns,
and Dar-es-Salaam, G.E.A.—Ber-al-ca-dar, if
we remember rightly.] Dr. Thomatis tells us
he was somewhat disappointed at the result
of the experiment in Ceylon—the effort of Mr.
J. W. Chas. De Soysa not representing, he
thought, what could still be done with season-
‘able planting and the most careful attention.
Possibly Ceylon was not the right climate
for it, as the fibre produced here showed
some degeneration from the parent stock.
But for those who are willing to try again,
Dr. Thomatis thinks there would be no difti-
culty in supplying seed through the Ceylon
Agricultural Society to approved growers and
lending the money required on the Company’s
easy terms. The Agricultural Society would
do well to approach the Head Oftice of the
Company—‘‘ Der Baumwohlgesellschaft Cara-
vonica,” 86 Constanzerstrasse, Berlin W_ (15)
—and obtain full particulars at an early date.
{t would be interesting if those who are per-
suaded by Mr Stewart McCall’s forthcoming
Report on the conditions of the North-Central
Province, to take up cotton growing, wero at first
to grow both the Egyptian species and Caravon-
ica hybrid and compare results—with a view to
further operations. Caravonica is said to yield
one ton to theacre (2,240 lb.), about 90 per cent
of pure fibre being obtainable from a properly
grown crop, against a minimum ot 300 Lb per
acre which Mr McCall thought probable here
with Egyptian and 130 lb. per acre actually ob-
tained at Maha Illupalama so far. ‘‘ Caravonica
fetches over six times the price and gives two
or three times the yield,” Dr. Thomatis said,
on hearing the Ceylon figures.
ORCHELLA WEED.
The Imperial Institute, London, reports a
shortage of this dye-weed and enquires whether
any merchants in the island would be willing
to take the necessary steps to resume theex-
port of the weed from Ceylon. This Colony
was rather noted for its orchella weed at cone
time, we believe, and in a work of reference
we see that in 1851 in the Great Exhibition
some specimens were exhibited from Ceylon
whose estimated value was £389 per ton. In
the ‘‘nineties’’ we believe the trade in orchella
was very brisk. A great dealof it used to be
gathered in the Jaffna Peninsula. where it
grew on trees, and was sold by the
natives to merchants in Colombo for from
four cents to six cents. The weed is called
in Tamil ‘‘Marappasi.” The market price
varies but in 1889 £60 per ton was received
for the Ceylon article in London. In view of
the interest that is likely to be revived in this
commodity by the Imperial Institute’s inquiry
we quote from an article |by the late Mr.
187
Henry Meade, written probably about 60 years
ago, an interesting reference to orchella weed.
Some INTERESTING Facts,
We quote the following from the Tropical Agri-
culturist, Oct., 1889, as of special interest at
this time, in view of the report that there is a
shortage of the Weed in the London Market :—
At the head of the list of Dye Stuffs stands
the “ Roccella Tinctoria ” and ‘* Roccella Fuci-
formis,” the Orchella weed of commerce. This
article was first exported by myself, in the
beginning of 1859 ; it was found growing in great
abundance at Calpentyn, and over a range of
about fifty miles of the narrow strip of sand,
which lies between the Calpentyn lake and the
sea. HMnormous filaments of the ‘‘ Tinctoria, ’
some of them as much as eighteen inches in
length, by three-quarters of an inch in breadth,
were found hanging in clusters on the decayed
branches of the oldest mango trees, whilst the
mimosas and several varieties of ‘“‘asclepiadece ’’
furnished varieties of the ‘‘ Fuciformis,’ still
more valuable, The Palmyra trees and Coconut
trees were found to be thickly clothed with the
lichen, except in those instances where they
had been frequently climbed. There was scarcely
a tree or bush that was not covered, more or
less, with the Roccella, of the worth of which
the people were wholly ignorant. It has now
become a regular article of commerce. Except
on the tract of seaboard, stretching from Chilaw
to Tangalle, the whole line of coast exhibits
Roccellas, growing more or Jess luxuriantly, but
always confined to a narrow belt of vegetation
within the influence of the sea air, On the salt
marshes of the western coast, and on the
boarders of the lagoons it is invariably found,
and there is a large growth on the eastern side
of the Peninsula at Trincomalee, and about the
leways of Hanbantota. Where the roots are not
torn off, it is reproduced yearly. Though every
variety of Roccella is well worth gathering,
there are some kinds that are much more valu-
able than others ; and the following simple test
will enable anyone to ascertain the comparative
richness of the colouring matter which they con-
tain. Fill a bottle half-full of water, put as
much of the lichen in, as will leave room to
shake the contents of the bottle thoroughly, and
add as much spirits of ammonia as will make
the liquor unpleasantly pungent, Shake the
bottle occasionally during six or seven days,
opening it now and then to admit the air, and at
the end of that time the water will exhibit
arich purple colour, deepening in intensity for
about a fortnight when the maceration is com-
pleted. A comparison of the result of different
experiments will show the volourific value of the
various kinds of weed, and the test is one that
never fails. If a lichen fails to impart colour to
a mixture of ammonia and water, it is not a dye
stuff, whatever else it may be good for. The
Orchella dye requires no mordant. To fix the
colour on cloth it is merely necessary to pour the
solution above-described into boiling water, and
immerse tha wool or cotton to be dyed in it
for half-an-hour. The dye is not a permanent
one, but its extreme beauty will always make it
acceptable to manufacturers, who use it’ to
impart a finish to their goods,
188
MANURE.
Any information on this subject should be
gladly read by agriculturists, so the following
paragraph may strengthen planters in their
appreciation of bulky manure versus artificials :
Much to the surprise of those connected with the
Cleansing Department of Leith, a sudden demand has
arisen for the street sweepings, agriculturists now show-
ing a preference for this kind of manure. No less than
eighty tons of street sweepings are collected in the town
per day, and the fact that this is now so easily dis-
posed of would seem to suggest that farmers are viewing
with less favour artificial manure, the cost of which is
of course, so much greater.
I donot know whether my persistent writing
against artificial manures and in praise of bulk
is bearing fruit amongst the farmers near
Leith ; but I can see, with pleasure, the good
effect produced in my own neighbourhood.
Frequently I am told by some neighbour that
he has taken my advice and, for several
years, has spent nothing on artificials, but
plenty on feeding stuffs, so that his cattle
manure is far superior to what it used to
be, and the crops he is growing have im-
proved in alike ratio. Naturally 1 am pleased
to know that I have been of good service to
my neighbours, and, naturally, the manure
merchants don’t like me for having burst up
their little game. The street sweepings of Leith,
mentioned above, should be very valuable, as I
know how much benefited land is by being top-
dressed with the scrapings off a turnpike road.
CosMOPOLITE.
BURYING VS. BURNING PRUNINGS.
Lindula, Jan, 14th.
Srr,—As regards burying prunings my advice
is ‘‘don’t.” My experience of it, and thank
goodness a very small one, is thata 19 acres
operated on “‘ moreover basic slag” has ever since
been a martyr to leaf disease (grey blight).
Luckily I read Dr. Watt shortly after the experi-
ment; that put me off it for ever. He says, and
I believe truly, the roots take up disease from
the leaves.—Yours faithfully,
E. R. WIGGIN.
THe Economic DisPosat or Tra PRuNINGs.—
There can be no doubt about Mr E R Wiggin’s
opinion on this matter, It is expressed else-
where with an emphasis, which to borrow a
musical phrase, somewhat suggests the pro-
cess of ‘‘ forcing the note.” The tendered
advice, judging from Mr Wiggin’s experience,
may be very good for estates upcountry ; but
we know there are those who will question
its value to lowcountry properties. As a
matter of fact, we have heard very keen advo-
cates of burying prunings admit that on
upcountry estates, where the decomposition
of prunings is likely to extend over a con-
siderable time, there may be a danger of root
disease being started. On lowcountry estates,
where decomposition is rapid, it is held that
no such danger exists; and for every estate
upcountry where burying prunings has been a
failure, a case in the lowcountry can probably
be quoted where the result has been conspic-
uously successful, The estate of Mahawale for
The Supplement to the Tropical Agricullurist
instance is a case in point. That estate was
at one time considered a poor one. Prunings
have been buried since 1904. Artificial manure
is also applied and albizzia leaves buried ; and
the following table, showing an annual increase
in the crops, indicates that the burying of
prunings has had anything but an untoward
effect on the tea :—
1904 ... 482 lb. per acre.
1905 ... 552 ,, ‘s
1906 VOBTSICN ws
1907 . 746 ,, a
1908 ne As 8078; td .
The cost of production on this estate is 23°38
cents per lb. but that includes the supervision
of 650 acres ot rubber. If this were deducted, the
cost would approximate 22 cents. ‘¢ Quod cibu
est alvis, aliis est atre venenum” appears to be
true of estates as of individuals; the question,
therefore, seems more or less to resolve itself into
this: that what can be practised with safety and
much benefit on some estates, may be attended
with the most disastrous results if tried on
others where different conditions prevail.
THE COPRA INDUSTRY.
IN SINGAPORE.
It has been brought to my notice on one or
two occasions recently that the Singapore market
price of Copra is nearly always less than that
quoted for Ceylon and the Pacific Islands, In
order to ascertain’ the reason of this I recently
made careful enquiry into the state of the
market and the quality of the Copra offered for
sale. What surprised me most was the very
poor quality of the Copra imported from the
surrounding Islands and the Malay States com-
pared with that from Java and other Dutch
Islands. After examining numerous samples
taken from consignments from many different
parts I am not surprised that Singapore prices
do not compare favourably with those of other
markets, ‘There are several causes which
account for the inferior quality and price of
local copra. The principal cause appears to
me to be the absence of some systein of super-
vision over the native and Chinese Growers.
I believe that in Java and other Dutch Islands
the Dutch Government examines all Copra for
export and only that which is up to standard
quality is allowed to be shipped. This, in a
great measure, accounts for the excellence
of Dutch Copra. The second cause is that
it is a common practice to pick the coconuts
before they are quite ripe, thus accounting for
the large quantities of thin, soft and decaying
Copra on the market. Quantities of good ripe
Copra are frequently ruined by mixing it with
this half-matured stuff. The third reason is
that the Copra is badly dried. That said to
be sun-dried is only partially dried and as soon
as put in bulk becomes mouldy and _ rots.
That said to be kiln-dried is practically roasted.
A fourth—and by no means least important—
reason is the absence of any form of beneficial
cultivation on the estates. In the majority of
instances trees are never by any chance manured,
nor is any form of beneficial cultivation prac-
tised. The result of this neglect is an inferior
and Magazine of the Ceylon Agricullural Society.
Copra, poor in oil-producing qualities. I am
now referring to Malay and Chinese owned
estates which comprise practically the whole
industry. It is well-known that European
owned estates produce Copra of the very highest
quality; but, unfortunately for their owners,
the poor quality determines the market ear
Ceylon Copra obtains a better price, chicfly
because the large majority of coconut estates
there are owned by Huropeans and under
European management and every care is taken
to turn out Copra of first quality. The Pacific
Islands Copra maintains its advantage in price
principally because Messrs Lever Bros. and other
well-known soap manufacturers have extensive
interests there. They have representatives on the
spot who insist on first-class Copra being sup-
plied and in return pay the highest price. The
difference in price between good and bad Copra
in Singapore is about $1 per picul. The present
price for first quality is about $7°50. As the
price rises, it is customary for many native and
Chinese growers to resort to the injurious
PRACTICE OF RUSHING QUANTITIES OF UNRIPE,
BADLY DRIED COPRA
on the market in order to catch the higher
rate. This is a practice which cannot be too
strongly condemned. The principal sources
of supply are Dutch Borneo, the Natunas and
Anambas Islands, Johore, the Malay Peninsula,
and the Dutch Islands generally. Singapore pro-
duces over 3,000 piculs of Copra per month, chiefly
from Tanjong Katong and Passir Panjang. This,
with the exception of a small quantity from
European estates, is badly dried and contains
a large percentage of unripe nut. Dutch Copra
trom Billeton and Banka is principally kiln-
dried and arrives clean, well-dried and of good
quality. That from Padang, Sumatra, is in
small pieces, well-ripened, dry, dark and oily in
appearance and contains more oil than any
other Copra imported to Singapore. This is due
to careful cultivation and none but well matured
nuts being gathered. The Celebes give us a
good Copra, well dried from fully matured nuts,
yields an excollent oil and shews careful pre-
paration. Asahan exports fine large Copra, ripe
and fairly well dried both by sun and kiln.
Pontianak produces dry Copra of fair quality
containing a small percentage of unripe nut.
Saigon (Singkawang; Coprais of good quality,
dry, and shews careful preparation. ‘l'ernate
Islands Copra is very good, generally dry.
Kelantan Copra is good but that from Johore,
(Batu Pahat) is very wet, unripe and mouldy.
Rhio sends good samples of Copra, but occasion-
ally the quality canuot be depended on. | have
recently seenshipments from Malaccaand Muar
which were very bad indeed: in fact, it is said
that Copra from these two places is the worst
sent in to Singapore. In one store I saw several
lots heating s» badly that it was impossible to
bear the hand between the sacks. (Quite half

madeatdrying. [am informed on good autho-
rity that the quantity of bad Copra from
Malacca is steadily increasing.

The exports of Copra are to Russia, France,
Spain and other continental ports and recently
to the United Kingdom. The exports of coco-
nut oil from Singapore in 1907 reached 159,801
piculs of which 40,163 piculs were imported
chiefly from Pontianak.

in each of the 5 years 1903 to 1907, and for 9
months of 1908 are : --

The Director of Agriculture has stated in his
annual report for 1907 that this important
branch of the Agriculture of the Federated
Malay States has increased in acreage by seven
per cent. during that year, and that the total
area under coconuts at the end of the same
period was 112,500 acres. These facts and the
above figures demonstrate the importance of
the Copra Industry to the Peninsula and sur-
rounding Islands and also shew that there is a
renewed interest in not the least important of
our agricultural staple industries. Itis hoped
that this renewed interest will bring about
better cultivation and induce growers to take
more pains in the preparation of their produce
for market, / T. Witson Main.

AMERICAN COCONUT OIL MARKET.
INCRESING USES AND DEMAND.
Chicago, Dec. 16, 1908.—The demand for
coconut oil has firmed up and prices are higher
than they have been for some time. Thisisa
condition that was hardly looked for by the
trade. Not within many years: has
THE OUTTURN OF COPRA
the raw material from which the oil is
made, been as large as it has within the past
year. Every island in the Pacific from which
the trade receives copra contributed more thau
its usual quota, Importations into this country
have been very liberal, though forming a smail
part of the total productions. The two mills on
the Pacific Coast have been kept in constant
operation during the greater part of the present
Season, and the production of the domestic oil
is reported to have been much heavier than it
was last year. And yet, in spite of the larger
yield of copra, in spite of the greater production
of oil, the demand for the latter is now so keen
that makers and importers alike are forced to
190 The Supplement to the
advance their prices. ‘This is declared to be due
to the larger uses to which the oil is now being
placed. The
EDIBLE OIL IS BECOMING MORE AND MORE
A FACTOR
in the trade. The candy manufacturers
are using it to a greater extent than
ever before, the biscuit manufacturers are
finding more use for it every day, and the oil
is now being devoted toa great extent to the
making of butter, which shows chemical com-
binations very similar to those of the ordinary
commercial cow butter. Of course, the chief use
of the oil as yet is in the manufacture of soaps,
where the demand is greater than ever. Russia
is declared to be a heavier user of the oil for
this purpose ‘than ever before. With all the
increase in the supply of copra, the absorption
is said to have more than kept pace.
California oil is a product which under the
present conditions can hardly compete with the
regular Ceylon and Cochin oil handled by the
importers, except in the territory west of the
Missouri River. The great cost of freight keeps
the American makers out ofthe Eastern and
Middle West markéts, Kansas City being about
as far east as the California makers can come.
Now and again a carload is sold in Chicago, but
this is the exception rather than the rule.
The recent appearance of a representative of
one of the Western coconut oil manufacturers
before the Ways and Means Committee of Con-
gress, advocating
THE PLACING OF A DUTY ON THIS OIL
raises a question as to the advisability of a
tariff. The position of the makers of the oil can
be well understood, When it is considered that
a shipment of oilcan be made from Marseilles
to Chicago cheaper than it can from San Fran-
cisco, it canbe seen that the chances of the
American makers, whose factories are located
on the Pacific Coast, to be near the base of
supplies competing with the French broker, are
very slight. The difference in the freight rate
from the Pacific Coast to Chicago, and the rate
from New York to Chicago, is about 48c. in
favour of New York. Itis urged that a tariff of
3c. per pound on the oil wovld place the oil
manufacturer in a position where he would have
an even chance with the foreigner. It isa well-
understood tact that the operations of the bigger
mill of the two on thecoast have been carried
on at a loss, simply because the oil could not be
sold in the country of its production outside of
a limited area—an area where the demand for
the oil is not the heaviest. If the theory ofa
tariff is to build up infant industries, it is urged
that here is an industry in an infantile condition
which might be made a big factor in the employ-
ment of many men inthe future. Without that
tariff, there can be little chance for a broaden:
ing of the market, the makers urge.
Chicago price for East India Cochin is 7#c.,
and for Ceylon Cochin, 7ic. spot and Jan-March.
California Cochin is quoted at 74c,, and Ceylon
at 63c.—New York Oil Reporter, Dec. 21.

THE U. S. A. SOAP MANUFACTURES
IN TARIFF REVISION.
OpPosING THE TAX ON Coconut O11 ENTERING
THE U.S. A.
Washington, Dec. 4.—An important confer-
ence of leading representatives of the soap
industry was held in this city on Monday of
this week for the purpose of arriving at a basis
for the representations which the soap trade
desires to make to the Ways and Means Com-
mittee with respect to the revision of the
Dingley tariff act. The coconut oil producers,
appeared to regard the revision of the Dingley
act as affording an excellent opportunity to
secure protection not only for factories operat-
ing in the United States, but for those recently
established in the Philippine Islands, The re-
presentatives of the latter factories were careful,
however, to state that their proposition for a
relatively high duty on coconut oil when im-
ported into the United States from a foreign
country was conditioned upon the establishment
of free trade between the United States and the
archipelago. Itis assumed that m connection
with the general revision of the existing tariff
law Congress will authorise mutual free trade
with the Philippines, except in sugar and to-
bacco, upon the importation of which certain
restrictions will be imposed, and itis obvious
that the duty on foreign coconut oil with free
oil from our insular possessions would give a
tremendous boom to the Philippine factories
established within the past year or two.
The soap men have viewed these developments
with considerable apprehension, and at their
conference in this city they did not hesitate to
denounce the efforts to impose duties on the
raw materials of the soap industry and to insist
that the tax thereon be entirely eliminated. —

A GOCONUT PEST IN COCHIN.
A Sprcrant Report.
The Cochin Gazette received today contains a
Special Report by an officer of the Madras
Department of Agriculture on the Pura Lepida
found affecting coconut treesin Cochin. The
Report after detailing the systematic position,
records of occurrence, distribution, life-history,
food plants and enemies of the pest, goes on to
deal with the nature and extent of its attack
on the coconut palms of Cochin. The last
section of the Report deals with remedial
measures, in which the investigator says:—
‘Considering the height to which the coconut
palm grows and the great extent of the foliage
to be reached, none but very powerful spraying
machines can be of any use. Hence under
present conditions, checking the pest with
insecticidal sprays is out of the question. The
best method, as to checking the increase of the
pest, would, on the part of the Jand-owner, be a
careful look out for the appearance of the pest
and prompt action finding it out. The infested
fronds must be cut down and instantly burnt;
the cocoon must be carefully looked for on the
crown at the base of the leaf stalks and after
and Magazine of the Ceylon Agricultural Society.
being collected must either be buried deep into
the soil and trampled, or summarily consigned
to the fire. It was found from enquiry that the
post in question was no new thing in the State.
Some of the people aftirmed that the same pest
had about 10 or 15 years ago appeared on and
caused much damage to trees in the narrow strip
of land between the sea and the backwaters, to
the north of British Cochin, From the Report
of the Superintendent of Agriculture, it may be
seen that the pest had been observed some 30
years ago in some localities. From this it is
evident that the pest is neither a new nor
a rare thing in the Cochin State. It seems to be
always present in that vast coconut forest,
breeding normally in small numbersin some cor-
ner or other, and only sporadically increasing so
as to become a very serious pestto small areas. It
seems ordinarily to be keptincheck by its bracon
parasite. he presence of a hyperparasite on the
latter is again an indication of the long stan-
ding establishment of the pest andits parasite
within the Coconut belt. The trees attacked,
in general, completely recover, death occurring
only in very rare cases. The increase of the pest
can, moreover, be easily checked by cutting
down affected branches and burning them. Again
the pest is one thatis very slow of increaseas may
be inferred from the long duration of its pupal
period. Under these circumstancés, the nature
and habits of the pest do not seem to justify the
wholesale panic felt by some of the suffering pro-
prietore since it is by no means such a dangerous
and invidious foe as the fungus causing the
coconut palm disease.”—Jf, Mail, Jan. 6.
PESTS IN THE F.M. S.
A New ORDINANCE TO PREVENT INTRODUCTION,
Nearly all the Colonies especially those of the
tropics have now regulations as to the import-
ation of plants or seeds from countries in which
there is any animal or plant pest affecting these
plants, and through which the disease is likely
to beintroduced. These regulations are intended
of course to protect cultivated plants only, and
are usually, but not always,enforced when there
is a definite disease affecting an extensive culti-
vation in the country of the would be exporter,
and the same cultivation without the disease in
the country to whichit is intended to export
the plant. Thus Jamaica for many years prohi-
bited the importation of any living plants
of whatever kind from any country which there
was cultivated coffee affected with Hemilesa
Vastatiz, and thus kept the disease out of the
country fora considerable period. There are
diseases which no man can possibly prevent
the invasion of as the distances which spores of
fungi can float on the wind is very great and in
countries at all contiguous they can drift across
ifthe wind is suitable. The bee hawk moth,
the caterpillar of which was so destructive to
the coffee some years ago inSelangor, is also a
very long flyinginsect. I foundit quite abundant
in Christmas island over 200 miles from the
nearest land it could have come from.
But these are rather exceptional cases and
most plant diseases appear to be accidentally
imported by man. Inthe interests therefore of
191
the great areas of cultivations of plants now-
a-days, it is essential to prevent as much as
possible any disease that has unfortunately ap-
peared in one country from invading another.
Hitherto there has been no ordinance per-
mitting the Colony to refuse to allow to be
imported diseased plants, and it became clearly
desirable that it should have this power. Hence
at the suggestion of the Director of Gardens
the following Ordinance has been passed :—
STRAITS SETTLEMENTS ORDINANCE
No. XIII oF 1908.
An Ordinance to prevent the introduction into the Colony
of pests and insects destructive to trees, plants and crops.
Itis hereby enacted by the Governor of the Straits
Settlements with the advice and consent of the Legislative
Council thereof as follows :—
1. This Ordinance may be cited as ‘The Destructive
Pests Ordinance 1908.”
2. The Governorin Council may from time to time
make such orders as may to the Governor in Council ap-
pear expedient for preventing the introduction into the
Colony of any insect, fungus or other pest destructive to
agricultural or horticultural crops or to trees or plants and
for preventing the spreading in the Colony of any such
insect, fungus or other pest.

CAGAO AND GRUBS IN JAMAICA.
Hundreds of cocoa trees in Jamaica, we read,
are dying from a root trouble which is said to be
caused by the attacks of asmall white grub, This
grub is of the same nature, if not identical, with
the larvae of the orange weevil, the “ Fiddler ”
bug. Small doses of lime spread over the soil in
the radius of the trees is found to do good, but is
not entirely effectual if the trees are badly at-
tacked. The best way that has so far been
found to get rid of the grubs, so as to kill
them wholesale, is by the use of Bi-sulphide of
Carbon. For 10 years back it has been em-
ployed to kill weevils in grain and the ants
which make nests at the roots of fruit trees. Tt
is a volatile gas, heavier than air, so that when
applied on the top of a barrel of corn or on the
top of an ant hill, or around the roots of trees,
it sinks and kills all animal life below, within
limits of course. To apply this to a cocoa
tree, or to every cocoa tree ina plantation, is abig
192
operation; and a doubtful one, because a few
drops of it are not guaranteed to kill the grubs
through the whole soil radius of a cocoa tree,
and too much of it may dainage the trees. It
is, however, recommended to be tried on trees
that are thought to be attacked by beginning a
yard out from the trees and at intervals round
each tree, ramming the fork in the soil, then
dropping a few drops of the Bi-sulphide in the
hole made by the prongs of the fork, drawing
earth over the holes at once.
THE NEW RAPID SYSTEM OF
TAPPING RUBBER.
We understand that the report on the new
system of extracting latex, referred to the
Messrs. Lee Hedges & Co.’s circular of Novem-
ber, (see page 591 of December T. A.) which
has been prepared after witnessing a demons-
tration shortly before Christmas, has reached
Mesers. Lee Hedges & Co. from Joseph Fraser
and Clements. It is not above-named for a copy
of for publication. Weunderstand, however, that
—though, of course, it is too soon yet to obtain
evidence as to how often the same surface may be
tapped by this system in a year, without injury
to the tree, or as to the effect on the tree after
some years of numbers of tappings, the advan-
tages claimed have been established, namely :
1) cost of plant not above usual current methods;
2) simplicity ; 3) reduced cost of production ;
4) little—or no apparent—damage to the trees ;
5) labour-saving ; and 6) quicker and possibly
increased returns, We believe the system can
be much varied or modified at will and is not
expected to be more fatal to the tree than
other methods (possibly the reverse) if it be
not employed entirely in order to extract the
maximum of latex in the minimum of time.
Jan. 7th.
Dar Sir,—In connection with the new tap-
ping system of Messrs. Lee Hedges & Co., on
which Messrs. Joseph Fraser and Cloments’
report is eagerly awaited, it is of interest to
recall! that Mr. Petch, the Government Myco-
logist, has spoken against the use of the
pricker on several occasions, and, I understand,
he has not yet seen any reason to alter his
opinion. . I hear, too, that the new method
of tapping rubber, which is now being boomed,
involves the use of the pricker. If it does, the
inventor must wait until he can demonstrate
what is the condition of the tree two years
‘after tapping, before he can_ speak of the
success of his method. But Dr. Willis has
_ given his approval of the system, though I
cannot discover that he has considered _the
pathological side—the structure and reactions
of a Hevea tree. I am strongly of opinion that
the use of the pricker causes the formation
of lumps on the renewed surface and makes
it untappable. You have only to look at the
trees Mr. Herbert Wright tapped at Henarat-
goda two years ago.—I am, yours faithfully,
EXPERIENTIA DOCET.
The Supplement to the Tropical Agriculturist
THE TREATMENT OF ACID SOILS FOR
RUBBER AND OTHER CULTIVATIONS.
A series of experiments have been begun
by the Department of Agriculture on some low
lying flat land which has abnormally acid soil,
rendering it unfavourable for the rapid growth of
root growth of rubber or other cultivated plants.
The presence of a too large proportion of acid
in peaty soils is due to the existence of a
large proportion of humic acid which is a
brown or black substance produced by decay-
ing vegetable matter. This decomposition is
greatly facilitated by heat, air, and moisture
and by the presence of putrefying nitroge-
nous matter. The conditions in many clear-
ings in Malaya are therefore specially suited
to the formation of an excess of humic acid
which exists in many places to such an ex-
tent that the roots of young rubber are
not able to grow and the plants grow
without vigour and in some cases succumb.
Such soils are physically and in other respects,
most suitable for healthy and rapid growth of
rubber and when the amount of acid has been
reduced they often produce exceptionally fine
rubber. The question of the naturalisation of
such soils in the shortest time is of great im-
portance. The only method used at present is
to allow the sun free access to the soil and by
this means and plentiful drainage to gradually
eliminate a proportion of the acid. This is
however a lengthy and not always successful
method and a much quicker plan is to add
such proportion of basic substance such as lime -
as is needed to neutralise the acid in the coil. A
very large supply of natural phosphate is being
extracted from Christmas Island and can be
delivered comparatively cheaply at 8. 8. and F.
M.S. ports. This raw phosphate not converted
into the superphosphate will be tried on acid
soils. The advantage in using this manure is
that the raw[pbosphate i.¢., phosphatic rocks
exactly as they are obtained in nature is cheaper
than the manufactured superphosphate and the
acid in the soil of the superacid lands will con-
vert the phosphate into superphosphate and by
so doing the soil will more rapidly lose its
acid and become neutralised and the available
plant food in the soil greatly increased. The
costs of such an application of raw phosphate
will be determined by experimenting with
different quantities per acre to discover
the smallest amount necessary to render the
soil favourable to root growth of rubber.
In certain cases the lack of vigour in_ the
growth of young rubber on acid soils has been
attributed to dampness of soil, fungi or other
diseases of the roots and it will be well if in
cases where there is reason to suspect that
the chemical condition of the soil is the cause
of the lack of progress of rubber plants a
portion of the field be treated to reduce the
acidity. On some of the super acid soils a
litmus Pape pressed against a handful of the
damp soil gives in a short space of time, some
few minutes, a marked acid reaction i.e. is
changed to a pink colour. This may be used
as a rough test of the relative amount of
acidity in the soil.

PrERAK.—We have just received a letter dated
3rd Jan., 1909, from Taiping, Perak, in which the
writer states :—The growth of Rubber is very
rapid. Applications for large areas of land for
Rubber are still coming in to Government. A
Mr. Ross, who has already 800 acres planted, is
applying for another 600.—Cor.
Borneo.-—As a proof how eminently suitable
British North Borneo is for the cultivation of
Para rubber, it is stated that sixty trees, about 64

last year 107 lb. of rubber, or an average of about
13 lb. per tree.—H & C Mail, Jan. 8,
In JAvA AND SumatTRA,—Rubber Cultivation
is expected to show considerable development in
thefuture. At the present time it is estimated
that in the Netherlands East Indies over 87,500
acres are devoted to rubber, of which 57,000 acres
are situated in Java, Many of theold plantations
consist of Ficus elastica, but latterly the Para tree
has been extensively planted.—H ¢ C Mail, Jan. 8.
Souru AcHEEN.--Inthe Tamiang district, South
Acheen, rubber cultivation is going ahead so far as
labour difticulties will allow. The planters freely
avail themselves of Achineselabourers, They are
found to be far preferable to Malays, who will
not work on the fields if they can help it, so long
as fishing gives them a means of livelihood. The
Governor of Acheen, who lately visited the dis-
trict, was much struck by seeing how Achinese
could be utilised for estate labour, and promised
to do his best to open up Tamiang for planters.

A Brkp’s Eye ViEw oF RUBBER PLANTING, —
Anyone travelling on the branch ofthe FM SR
which connects Kuala Lumpur with Port
Swettenham has been able during the last few
years to observe from his seat in the railway
carriage the different stages through which a
rubber estate passes from the clearing of the
virgin jungle to the tapping of the established
trees. In addition, says a correspondent, the
traveller can now see in practice several exam-
ples of the clean weeding and weed exterminator
theories, some estates with nothing but bare
earth under the trees, others with crotalaria and
others with passion flower.—Matau Mail, Jan. 18,
RuBBER IN TRINIDAD.—A gentleman who was
recently in Trinidad and proposesto return with
a view to settlement in the colony, writes from
Mexico, where he was staying on a rubber estate
of 400,000 trees as follows to a Trinidad paper :
—‘‘]T thought it might interest you to know
that the ten-years-old Rubber Trees (Castilloa
elastica) here are not larger if so Jarge as those
of four years old of which I took photographs
194
at New Lands and they are certainly not
as heaithy locking. This 1s the home of the
Castilloa, and it grows wild in the woods but
from what I have seen ofit inCeylon, the Malay
States, etc., I should decidedly say that it does
best in Trinidad, if New Lands Rubber be
taken as a sample.”
Stack Estate MANAGEMENT IN JAVA.—On an
estate in Asahan, Delhi, which is managed by
a company domiciled in Germany, serious com-
plications have arisen, The outlay on the spot
has, of late increased so alarmingly that the
directors sent out two delegates to inquire
what had brought on this untoward result.
Commenting on this incident, the Deli Courant
calls attention to the lack of control over certain
estate managers who are left free to charge
the property with outlay which should be
placed to their personal account. This is done
mostly froia carelessness rather than out of set
purpose. So loose is the system that the
auditing of estate books is seldom given thought,
though stricter control would check mismanage-
ment, lavish outlay, and uncalled-for expendi-
ture.—Straits Times, Jan. 20.
QUEENSLAND,—Though still in the experimen-
tal stage, is making progress. Six varieties of
rubber-producing plants now under cultivation
are admittedly likely to be of use to the country,
and are growing well. As yet only four have attain-
ed maturity. The Ceara rubber has only been
spasmodically tapped. While under ten years
of age or so, experiments have been unsatis-
factory; but as they increase in years, the flow
of latex seems to increase, and to flow for a
longer period after the bark is cut. On the Ram-
bong trees experiments have indicated that,
with cultivation, a size may be attained rend-
ering it both possible and worth while to com-
mence tapping operations at nine years or so
of age, and possibly earlier. The large trees
growing in Queensland are some 16 years of
age, and will give as much as 5 1b. of dry rub-
ber per annum. Tapping operations are sys-
tematically carried out on the small plantations
of Para rubber trees, which are now eight years
old, in the Government Tropical Nursery in
Kamerunga.—L & C Express, Jan. |.
Sr. Lucia.—Rubber plants (Castilloa, Hevea
and Funtamia) have been raised in considerable
number at St. Lucia Botanic Station, and some
estates have made experimental plantings. In
1906-7, the number of rubber plants distributed
from the station was 18,167, of which, however,
only some 7,0C0 were planted in theisland. In
1907-8, the total number sent out fell to 7,438, of
which only about 2,000 were distributed locally,
and the Curator states that at present there is
practically no demand for rubber plants at St.
Lucia. The plantings already made will continue
to be kept under observation and experiment, and
a good stock of plants still exists at the Station.
A consignment of ten packages of seeds of
‘© Hevea brasiliensis,” comprising a total of
2,059, was received from Ceylon in the past year.
The seeds were packed in charcoal dust, and
were altogether about two months in transit,
Of the seeds received, 947, or about 46 per cent.,
germinated, Observations on the condition of
The Supplement to the Tropical Agriculturist
the packages on arrival indicate that the best
results were obtained from the seeds in those tins
in which, on arrival, the charcoal dust was dry.
The Curator, in his latest Annual Report,
expresses the opinion that Castilloa rubber trees
will thrive exceedingly well in St. Lucia, if due
consideration is given to the selection of suitable
soiland locality.—W.I. Agricultural News,Dec.12.

S. NiegeRra.—Rubber is an important item in
the export trade of Southern Nigeria, and it is
consequently interesting to note that the planting
of rubber trees by the natives has been steadily
encouraged by the Forestry Department, and that
in some districts the plants are doing very well,
and give good promise for the future. According
to Mr. Birtwistle, the Government Commercial
Agent, it is now generally realised that not until
the rubber trees are owned by individuals, who
will see that they are duly protected, can this
industry in Nigeria be looked upon as one ofa
permanently-progressive nature. Thousands of
trees in the forests, which are practically a ‘‘no
man’s land,” are destroyed each year by over-
tapping, and, although every effort is made by
the Forestry Department to regulate the gather-
ing and to prevent indiscriminate bleeding, the
task in so large a country and amidst dense
forestsis an extremely difficult one. Incidentally
it may be observed that a decade ago the ex-
ports of rubber from one province alone averaged
over five million pounds weight per annum.—
Haé C Mail, Jan. 1.
Sincaporr Ruspper Factory.—The Neder-
landsche Gutta-Percha Maatschappij (Nether-
lands Gutta-Percha Company) report tor the
business year 1907 a deficit of 101,661°154 florins,
which, added to the former deficit, brought the
total to 249,358°574 florins. The deficit for 1907
includes 13,001°323 florins written off for de-
preciation,
and Magazine of the Ceylon Agricultural Society.
The directors state that the decline in selling
prices of gutta-percha caused a loss as to the
product in stock at the beginning of the year.
There waslarge expenditure in starting the rub-
ber goods factory, at Passir Panjang. The hope
is entertained that better conditions will now
prevail. Additional capital has been provided,
and profits are looked for from the Singapore
plant, as well as from the leaf gutta business,
which is the primary object of the company.
The idea is being considered of manufacturing
goods from the company’s own raw product,
The gutta-percha plantations were extended to
285 bouws[402°82 acres], and 15 bouws have been
planted in Hevea rubber—about 20,000 trees—
which number this year is to be increased to
75,000. The greater part of the gutta-percha
has been interplanted with cinchona (quinine),
and 5,500 florins, net, was derived during the
year from the sale of bark. The plantations are
in south-west Java, and the administration in
Holland.—Sétraits Times, Jan. 11.
THE PINEAPPLE INDUSTRY.
THe PingaPrLe Inpustry—is the subject of
an informing article reproduced on this page.
Who is there that grows pines on a large
scale in Ceylon?—and what has he to tell us
about them ? We protest against Ceylon pines
being called insipid, even if they have not the
flavour of those fine specimens which cost half-
a-crown or more at home.
That there is a huge demand for first-class
pineapples in India, and almost a total absence
of supply, will not be readily denied. To be
sure, pineapples are grown more or less exten-
sively in almost every part of India; but, in the
vast majority of cases, not the slightest attempt
has been made to improve the quality of the
fruit in any way and the actual result is that the
pineapples generally offered for sale in most of
the bazaars of India are not worth eating, and
would not be used except as cattle fodder in
countries growing good quality pines. It is not
that the pineapple is new to India; asa matter of
fact, it has been grown ir this country for
several hundred years, and in small tracts on the
Malabar Coast, in parts of Northern Bengal and
in places of Assam it has been brought to a
certain state of perfection. But the demand for
Indian-grown pineapples with any semblance of
flavour 1s so greatly in excess of the supply that
unripe and often
INSIPID PINEAPPLES FROM THE STRAITS SETILE-
MENTS, CEYLON AND MAURITIUS
find a ready sale at 2to 4 annas each. On the
other hand. we have heard of a small garden in
Northern Bengal growing luscious pineapples
which has no difficulty in selling them at 8 annas
apiece. The same sort otf thing is probably
done in other parts of the country on a small
scale, but the broad factis, as Sir George Watt
tersely puts it in his revised edition of the Com-
mercial Products of India, just issued : ‘‘ Little
orno effort has been put forth either to im-
rove the quality or to develop on a commercial
hana the industry of pineapple growing, which,
it would appear, might be originated with ad-
vantage to India and profit to those concerned.”
195
It may be interesting at this stage to make a
rapid survey of what has been done in other
countries in establishing the pineapple industry
on a commercial basis. Fifty years ago the pine-
apple was unknown in Florida: today one may
stand on any elevated position on the East
Coast of Florida and look out for miles over
solid fields of pineapples, no other cultivated
crop being in sight. The red Spanish pineapple
comprises about 98 per cent. of the total plan-
tings, Abbaschi, Smooth Cayenne and Porto
Rico making up the remainder. The crop an-
nually produced is considerable, being more
than half-a-million crates, each crate Tholdiad
from 18 to 48 pineapples according to size. In
pe ilalp the preserving and tinving of pine-
apples is a large and growing industry. In
1906 we tind that 707,495 cases of preserved
pines were shipped from that port, while the
export for 1907, the latest figures available, com:
prised 845,976 cases. There is avery large de-
mand for preserved pineapples in the United
Kingdom and on the Continent and this demand
Singapore largely supplies, Florida chiefly con-
fines herself to the export ofripe fruit. Buta
more striking example of what can be done in
establishing a pineapple industry on a sound ba-
sis in a short space of time is furnished by the
Hawaiian Islands, which promise to outstrip
both Florida and the Straits Settlements at an
early date. Here the industry was only started
about three years ago; but, under the gui-
dance of an enthusiast, has made such gi-
gantic progress that the output of preserved
pineapples in 1910 is estimated at 24 million
cans. In 1907 the output was 190,000 cases,
each containing 24 cans, but this is less
than half the estimated output for last year.
Already Bonolulu claims to be in_ pos-
session of the largest canning factory in the
world. This factory is to be capable of
handling 20 solid car-loads, or 300 tons of fruit,
in 10 hours, or at the rate of half-a-ton a minute,
When running to capacity it isexpected that the
factory will turn out between five and six thou-
sand cases of canned pines every day. And what
can be done on acommercialscale in Honolulu,
Florida and the Straits Settlements can pro-
bably be also done in a greater or lesser measure
in [udia, which boasts of every kind of climate,
from the mildest to the most severe.
A point in favour of the pineapple industry ig
that it is a comparatively simple one. The pines
may be grown upon land that will produce ordi-
nary vegetables, provided such land is well
drained even in times of excessive rain. To
obtain the very best results, however, a friable
soil and a porous subsoil are essential. Such
land stands drought well, as capillary attraction
is good under such conditions. In Florida pine-
apples are planted 18 to 24 inches apart, but in
the Bahama Islands as many as 20,000 pines
are planted on a single acre, each plant pro-
ducing one pineapple. This number of pine-
apples at 8,4, 2 or even 1 anna each would leave
a handsome margin of profit per acre. But it
is not only from the pineapples that tho profit
ismade: there are by-products. Pineapple
fibre fetches about £30 per ton in tbe London
market ; and, according to Sir George Watt,
there is a considerable demand for it in part of
196
Northern Bengal and the Deccan. In the Hono-
lulu preserving factory large quantities of juice
are obtained by crushing the course and parings
by running them through rollers of the sugar
mill type. The refuse may be used as fuel for
the furnaces, while the juice may be converted
into pineapple brandy, vinegar syrup and
extracts; and it has been recently suggested
that possibly pineapple sugar might be made
by boiling the juicein avacuum to the crystal-
lising point,
Such isarapid glance at the pineapple in-
dustry as practised in the countries named ; and
it may possibly be worth the while of some one
to consider whether it could not be successfully
established in one or more parts of India. We
may add that the imports of fresh fruit into
India last year were valued at R2,85,381, and,
although the imports of pineapples are not
separately recorded in the Customs returns, the
figures go to show that there is a substantial
demand for fresh fruit which, under present
conditions, this country is unable to supply.—
Indian Trade Journal, Jan. 21.
PINEAPPLE GROWING IN CEYLON.
We asked recently whether there was any-
one in Ceylon who grew really first-class pine-
apples. We have since had the opportunity
of seeing and tasting a very fine large pine,
prown on Mr. Jacob de Mel’s well-known
estate, Lilukewella, eight miles from Kurune-
gala, on the Kandy road. We are told that
very much larger ones are frequently grown on
the same estate, though this was well over 12
inches long and 18 inches in circumference. If
pineapples of such size, quality and richness of
flavour can be produced in Ceylon, sureby it
would be worthwhile for the industry to be
taken up here on a large scale by some enter-
prising agriculturist. Mr. de Mel’s are of the
kind known as Kew pines, and are far more
worth growing than the ordinary common little
country pineapple, such as is commonly sold
in the markets in Colombo and Kandy.

Dear Sir,—The ordinary weight of a good
Kew pine (Smooth Cayenne)—as grown here at
the Government Stock Gardens—is 15 or 16 lb. I
find ina Royal Botanic Garden’s circular (series
1, No. 15) the statement that the fruits of this
variety sometimes weigh over 20 lb., but no
definite maximum figure isgiven. Last year Mr
WA de Silva, Veterinary Surgeon, Columbo
Municipality, sent me a fruit, grown in his pro.
perty at Waga, which turned the scale at 21 1b
_ A few days ago, however, Mr M Suppra-
maniam, Broker, of Colombo, brought me one
which, on being carefully weighed, was found
to be 24lbs 5% oz.
Has this record been beaten P—Yours truly,

Why not D.C. Nut?
Viewing the increase that. Singapore has
established in its trade in copra, which is yearly
expanding, a correspondent thinks it is sur-
prising that local merchants do not import
machinery for desiccating coconuts. This has
been found to be a large and profitable indus-
try in Ceylon, and might conceivably do as
well in the Straits.—L & C Express, jan. 1.
MR. J. B. CARRUTHERS’ NEW
APPOINTMENT.
Mr. J. B. Carruthers, formerly Mycologist to
the Ceylon Government and at present Director
of Agriculture and Government Botanist in the
F.M.S., has, accepted a postin Trinidad. Mr.
Carruthers has done excellent work both in
Ceylon and the F.M.S. and tropical agriculturists
in the East generally will regret.that his services
are being transferred to the other side of the
globe. What the precise post Mr. Car-
ruthers has accepted is we are not told; but
it is thought at the Secretariat, and we think
it very likely, that he has been selected to
succeed Mr. J H Hart, v.1.s., as Superintendent
of the Royal Botanic Gardens at Port of Spain,
Trinidad, who after 32 years of valuable work
to Tropical Agriculture recently retired. A
new Department of Agriculture has recently
been formed in Trinidad and in the latest papers
to hand we note that subject to the approval ~
of the Secretary of State for the Colonies, His
Excellency the Acting Governor has appointed
Professor P. Carmody, F.1.c., F.¢.s., to be
Director. This appointment (which Professor
Carmody will hold in addition to his office as
Government Analyst and Professor of Chem-
istry) will date from November Ist last. The
following previously separate Departments
have been amalgamated to constitute the new
Department of Agriculture: (1) the Govern-
ment Laboratory; (2) the Botanic Gardens
(including the Experimental Station, Trinidad ;
Rever estate, Trinidad; and the Botanic
Station, Tobago); (3) the Government Stock
Farms at Trinidad and Tobago, and (4) St.
Augustine estate.
Jan. 27th.
Duar Sir,—That is interesting news you
published stating that Mr Carruthers is going
to Trinidad to succeed Mr Hart, as Direc-
tor of the Botanic Gardens, etc. I1t seems
almost a pity that Mr Carruthers has been
moved so soon from the Malay States, where he
is in the early stages of a lot of experimental
work, which he has now no chance of bringing
toa conclusion, and of which there will
likely be no results as his successor will, in’ all
probability, not continue on the same lines, As
he stated at the Ceylon Rubber Exhibition, he
hasa number of rubber experiments in hand
and these will takesome yearsto bring to any
result; his departure will be a loss to Malaya
planters. In the field of literature, too, .Mr
Carruthers has been active, and has shared the
and Magazine of the Ceylon Agricultural Society. 197
Editorship of the “Straits Agricultural Bulle-
tin,” which is a very useful planters’ periodical.
Butin Trinidad he will have the editorship of
another Agricultural Bulletin which, under Mr
Hart, has done very well; and Mr Hart filled
each quarterly number almost’ entirely by him-
self ; the volumes ofthe Bulletin are a monu-
ment of useful work done by him.
Mr Carruthers has good knowledge of rubber,
cacao and coconuts as cultivated in Ceylon and
Malaya which will be very useful in his new
career, for these products are being extensively
done in Trinidad. Rubber there is coming to
the fore. Cacao is a very paying product though
some Ceylon methods might well be adopted,
and coconuts are a product which is likely to
be extended. Asa botanist Mr Carruthers will
have great scope; and his home in Trinidad
will be among most pleasant surroundings. He
is certain of the good wishes of many Ceylon
friends including numerous planters,— Yours
faithfully,
ADMIRER.
FAILURE AND FORTUNE IN
NYASALAND.
“H. B.” responds to the criticisms in these
columns (October, 1908) that he had not told us
yet of any fortunes made in Nyasaland, while writ-
ing ofits advantages. From what he says, tobacco
would seem to be the most paying crop ; while
cotton has not been a success, We wonder if
the latter has been wrongly planted ? How-
‘ever, it will not be long now before Mr.
Stewart McUall, the new Director of Agricul-
ture, who believes it is the product for the
country, arrives on the spot to show the plan-
ters how it should be grown and harvested.
Mlanje, December, 1909.
In my hints to new-comers and investors, who
might be inclined to try their fortune in Nyasa-
jand, appearing in your issue of October last,
there was no reference to past failures, but
simply facts as they exist at present; but as
‘“Sceptical” refers to the
NYASALAND COFFEE CO.’s FAILURE
in 1901 without even paying a dividend to the
shareholders, I feel bound to reply—as it is
very probable ‘‘Sceptical ” was a shareholder,
and I myself was their V. A. When the
Nyasaland Co. was formed and during the
first few years of its existence, coffee was, to
all appearance, to be the future industry of the
country; and from crops that had been se-
cured from various estates, there was no getting
over the fact that money invested in this pro-
duct was to all appearance safe, and bound te
yield good interest in the course of time,
Jt is very doubtful if one man could be found
in or out of B.C, A., who, in view of the
circumstances surrounding the industry at the
time referred to, was then bold enough to
give an adverse epinion to the general one:
that B. C. A. was the home of the coffee tree,
and that there was a fortune in it. As time
went on, however, we began to make dis-
coveries that there were
NATURAL ENEMIES
of the coffee tree to contend with, of no trifling
nature. The larger the area that was opened up,
the more and more numerous those enemies be-
came, until they proved too much for the
coffee enterprise, and the result was wholesale
abandonment all over the country. Not only
the Nyasaland Co., but many others had to
close down after years of hard honest work,
which did credit to those who struggled to make
coffee pay. A great many
FINE BRICK BUNGALOWS
and godowns standing in the bush in the different
districts throughout the country bear evidence
of the confidence in the coffee enterprise, Nya-
saland planters were not satisfied, like Ceylon
pioneers, with a wattle and daub house to
begin with and wait to see whether the estate
was going to pay or not, for many of the houses
cost £500 to £600 and more—bhefore even a berry
of crop was harvested. To sum up the failure
of coffee in this country. If a coffee clearing
is opened and comes into bearing during
years that are ‘unfavourable’ for the deve-
lopment of insect pest, especially thrips (which
is mostly ruled by the early or late bush fires
and monsoon rains), a heavy crop and, perhaps,
two, can be secured ; but on the other hand, if
the season is favourable for breeding those in-
sects, the leaves and bark of the young wood
and berries are so damaged by their sinking
and puncturing the sap-cells, that one may as
well cut down the plants and let a sucker
grow up, for they are damaged for life, This
ACCOUNTS FOR MANY COFFEE CLEARINGS NEVER
‘ GIVING A CROP
in Nyasaland and even after cutting down the
trees the suckers have been also damaged in
the same way.
COTTON,
Cotton, for some who have been years in this coun-
try, has been a complete failure ; and for others,
it has given a very paying crop, indeed, but the
risks, of course, are a great deal too serious for
small capitalists. Was it not Mr J W Home who
had to abandon the cotton industry in the bed of
the Muturajawela tank, Ceylon (after spending
some £7,000), owing to insect pests, in the ’six-
ties or seventies? ‘‘Sceptical” wants to hear of
PLANTERS WHO ARE GETTING BIG RETURNS IN
THIS COUNTRY
at present. He might as well ask a man for
his Bank balance. The planters that are left
here are men of small means, who have managed
to tide over the coffee crisis, with few excep-
tions; but Ican mention one not very far away
from here, who sold about 7 tons of tobacco at
7d per lb., which cost very little to grow and put
on the market. I know another, who got 11d
per Ib. for 12 tons, aud yet another, who sold 20
tons of cotton at 74d perlb. 7 tons of tobacco
fetched 1s 13d per lb. not very long ago. Chil-
lies, I have just got the account sales for — tons,
sold at 56s per cwt. I could tell you of many
who have not only made a living here, but have
been able to clear out of the country with a few
thousands ; but not fortunes, that people are
usually in such a hurry to secure. How many
of the Ceylon planters made’ fortunes out of
Coffee, or even Tea? The writer thought that
10 years was enough to make a fortune in
Ceylon and 5 years in Nyasaland; but, alas!
—the schemes of mice and men!

THE LONDON RUBBER MARKET.
SOME HINTS FROM THE BROKER
TO THE PLANTER.
We have now received, and in most cases place
before our readers, the annual reports on tha rub-
ber market during 1908 issued by the principal
firms of rubber brokersin London. ‘They con-
tain, as far as we can discern, nothing that can
be regarded as discouraging to the producer of
plantation rubber in the East. In fact in every
case confidence in the great promise of the
industry is unmistakeably indicated ; and, in
not a few, invaluable hints are given to planters
regarding the form in which the raw product
is most acceptable to the manufacturers. The
interest of the trade in the plantation article
is broadening in proportion to the increase of
supplies ; and there is every reason to justify
the conclusion that, when still greater quanti-
ties are put on the market, a correspondingly
ready demand will be experienced for it. ‘The
production and imports into London of plan-
tation rubber during 1908 are given by Messrs.
Lewis & Peat as 2,100 tons against 1,250 tons in
the preceding year. At the present time no
department of the trade has refrained from
handling plantation rubber,and the above-named
firm assures us *‘ with confidence that now,
practically all manufacturers, large and small,
use plantation rubber and are likely to do so
more and more.” The large rubber firms are
making arrangements to deal with larger
quantities when the supplies increase as they
must do enormously during the next few years.
This is a gratifying and tangible sign of
practical interest in cultivated rubber, which
ought to stimulate planters to produce only
the best. It is very important at this stage
that the good impression made by the plan-
tation product should be maintained, and by
the adoption of the hints given by the London
brokers the quality improved and made still more
acceptable. The more important of the recom
mendations may be emphasized here. Messrs.
Figgis & Co. state that the manufacturers showed
a decided preference tor plantation rubber in
the form of Sheet, Biscuits and Crépe, and
with regard to the latter, planters are warned
that ‘‘it should not be drawn out too thin
or have visible air or steam bubbles in it.”
There seems to be a very ready demand
for pale pure Crepe, provided the preparation
has been thorough. Lhe firm quoted strongly
advises planters to wash and clean the rubber
thoroughly and to prepare as large a proportion
as possible of good colour and not to send
to London many qualities or small lots. Block,
they say, ‘‘has not beer in favour generally; and
unless clean resilient hard quality can be sent,
it may be better to ship as Crépe or sheet.
Pack it in good dry condition (excess of resin
much objected to.) Into strong cases of 1 ewt.
to 2 cwt. each. No paper, fuller’s earth, &c.,
to be used. Keeping different qualities and
colour separate; where practicable, keep im-
mature separate ; to send separately dirty bark
“pieces, and to wash out all the bark in Crépe,
Block and Sheet. All fine qualities should be loose
Crépe, Sheet or Biscuit—not run to a mass,”
The Supplement to the Tropical Agriculturist
These instructions are clear and definite and to
comply with them ought not to seriously tax
the resource of the planter. Messrs. Gow Wilson
and Stanton point out that while some samples
of plantation rubber have been pronounced
to be equal in all respects to fine Para, in certain
cases weakness and variation of quality are still
complained of, and they say “it is very
evident that every effort must be made to
raise the standard quality to a higher level.”
Messrs. Lewis and Peat point out that in the
case of ‘‘sheets’” a regular standard quality has
been established, making business easier both
for sellers and buyers. This firm also strongly
recommends planters to prepare their scrap in
Crepe form, taking care not to roll too thin, which
makes it weak and brittle. Scrap Crepe, they
say, ought to be hard. strong and gristly. Pre-
pared thus, scrap realises higher prices. They
also point out that very fine pale worms com-
mand a very high price; but that as the quan-
tities increase, the quality—as far as colour is
concerned—is not as good. There appears to be
apprehension that with quantity will come less
regard for quality on the part of the producer. It
is in the Ceylon planter’s interest that he should
strive to allay this fear. As to the market itself
it is very satisfactory to find the statistical
position so sound and to know that this is not
due to any marked falling off in supplies but to
the steady improvement in the trade absorbing
the surplus stocks. The world’s supply in 1908
was about 65,000 tons, against 69,000 tons in
1907 and 65,000 tons in 1906. The consumption.
in 1908 is estimated at about 67,500 tons; -
and on this point Messrs. Lewis and Peat,
give the cheering assurance that although
“Production must increase enormously during
the next few years, even now the trade is ready
to cope with it whatever its dimensions.”
The past year therefore, with its unexampled
fluctuations, was not entirely without points of
advantage for plantation rubber. The recovery
made by the market in the second half of the
year was remarkable and he would indeed be
deemed ‘‘a cheery optimist” whoa year ago
ventured to predict that 1908 would close
as favourably asit did. At the present moment
the market is quite as satisfactory as any
reasonable person could hope for and better
than most of us anticipated it would be a year
ago. We then had low pricesand large stocks: we
now havelow stocks and,comparatively speaking,
high prices. The future not being born, we are
not going to christen it. But without laying
ourselves open to the charge of making unduly
optimistic prognostications, we may say that if
the expert opinion of these London Brokers
is to count for anything, the outlook is dis-
tinctly promising. We have heard it stated
locally that one Ceylon estate has sold its crop
forward at 5s per Ib. If this is correct, one buyer
at any rate anticipates a high level of prices
to be maintained during 1909. Whether prices
tise or fall, however, planters cannot do better
than carry out to the best of their ability the
useful instructions conveyed to them by the
Brokers in London. By so doing they will secure
better prices for themselves and, what is still
more important, help to establish for all time
the reputation of Ceylon Plantation rubber,
and Magazine of the Ceylon Agricultural Society.
MESSRS. FIGGIS & CO.’S REPORT.
Fine Brazit, AMAzonas, BoLiviaANn, PERUVIAN
AND (WiLD) Meptiom.
1908 will be remembered as a year of record
variations in values and enormously increased
price at the close, compared with the beginning
of the year: also the constant large demand
for fine Para, which al! countries have wanted
in Jarger proportion than formerly. Asa result
the advance today compared to this date last year
is ls 8d per lb. on fine Para, but only 6d to 1s
on Negrohead and 10d on Caucho Ball. For the
reasons stated in our last annual, prices declined
last January and February, several American
factories continued closed ; consequently too
much Rubber was lefton the English market.
On 2lst February we had the lowest prices of
the year, Hard Fine Para being sold at 2s 9d,
scrappy 2s. A recovery soon ensued, and as
detailed beiow, prices advanced 1s per lb. With
eager American Regine and cornering of large
bear operators, we had a further great advance
in November, prices then being about double
those of February 21st. Mediums were only
saleable at very low prices till November,
and the disastrous results to importers aud
holders, seriously restricted imports, resulting
in stocks being abnormally smallnow. English
consumption of Rubber has been very large,
that of France and Germany good, Russia only
moderate, and America much less till quite
recently. We think invisible stocks must be
large in America, owing to her very free buying
this last three months. The European stocks
are exceedingly small. The world’s supply of
about 65,000 tons has been all consumed. In
1907 we had 69,000 tons, 1906 65,000 tons, and
we begin this year with very small stocks of
all Rubber (especially mediums).
‘‘Slab Rubber” was scarce and sold well,
‘* Ball” plentiful (and of good quality) and
very ready sale. ‘‘ Tails” only saleable at low
prices, The supply of mediums was much
smaller. West Coast African declined.
_ W.C.A.—Only 14,000 tons against 17,000 tons
in 1907, 17,200 tons in 1906 and 17,500 tons
in 1905.

There has been a further general improve-
ment in preparation, less of inferior and
“tacky,” much more of fine clean crépe—some
of very good colour realising high prices—and
nice resilient sheet.
The enormous variations and great advance in
prices since early October (fully detailed over
leaf), have resulted in very high ‘‘average price”
for Plantation during recent inontiis but, as we
formerly predicted, the difference in value corn-
pared with fine Para Brazil Rubber, lessens
with the larger supply of Plantation.
Manufacturers have shewn a decided prefer-
ence for Sheet, Biscuit and Crepe; the latter
should not be drawn out too thin or have visible
air or steam bubbles in it. Some lots of strong
thick Crépe sold very well.
We think it has been profitable to planters to
wash’and clean the rubber thoroughly, and to
prepare as large a proportion as possible of gcod
colour—also not to send many qualities or very
small lots. Block has not been in favour gene-
rally, and unless clean resilient hard quality can
be sent, it may be better to ship as Crépe or
sheet.

much objected to.)

Keeping different qualities and colours sepa-
rate, where practicable keep immature separate;
to send separately dirty barky pieces, and to

All fine qualities should be loose Crépe, Sheet or

Smoked rubber appears to have greater re-
siliency and to be more suitable for many pur-
poses than unsmoked. ‘* Smoking” prevents
the ‘“‘ proteins ” in rubber from decomposition,
and generally from ‘‘ tackiness.’’ All fine rubber
from Para is smoked.
During last January and February we had de-
cline in markets (from the values of Ist January,
viz., fine Para 3s. 5d., fine Plantation 3s. 11d_),
owing to the withdrawal from purchasing Rub-
ber by America, and the continued closing
there. of many factories.
The Swpplement to the Tropical Agriculturist : :
The lowest price was 21st’ February, when
fine hard Para was sold at 28 -9d. good sheet
Plantation (Malay) at 3s 14d. America showing
signs of revival, values rapidly recovered, and
advanced 1s per lb. by middle of May. Prices
were irregular till 6th October, when Plantation
sheet sold at 4s63d, Para 48s 44d. With
A STRONG AMERICAN DEMAND AND GORNER |
OF ‘* BEARS,” '
by 10th November the price was a further
is per lb. higher, and 17th November
the highest price of the year obtained, viz., 5s
5d fine hard. Para, whilst sheet Plantation
realised 5s 9d to 5s 10d. Values feil subse-
quently, and today fine Plantation is 5s 34d, fine
Hard Para 5s 1d to 58 2d, fine Soft 4s 94d.
The rapid fluctuations and extraordinary rise
in values appear hardly due to natural or
normal causes, but the world’s demand has
been more than equal to the reduced supply,
and at some periods our stocks have been re-
markably small, especially of fine Para. Total
stocks now are smaller than for many years.
Notwithstanding the serious losses in Brazil,
the supply from the Amazonas has increased,
but there has beena large reduction of Mani-
coba, Mangabeira and Pernambuco. Brazil
exported 40,000 tons.
Our doubts as to Synthetic rubber have
proved to becorrect. Itisnot mentioned now,
and common substitutes have been neglected
though cheap. A large trade in reclaimed
rubber, and quality improved.
Rambong has sold fairly well, especially small
lots of nice hard clean. Castilloa in small sup-
ply, but not liked even at low prices.
The world’s supply in 1908 was about 65,000
tons, against 69,000 tons in 1907, and 65,000 tons
in 14906. Consumption we estimate was about
67,500 tons. Of

REPORT BY GOW WILSON AND
STANTON, LIMITED,
13 & 23, Rood Lane, London, E.C., December
31st, 1908.
Tue Years Saues,—The quantity of Plan-
tation Rubber brought to auctionin London
during 1908 was 24,647 packages, amounting to
1,2954, tons, compared with 15,380 packages,
weighing S14 tons during the previous year.
The auction average price for 1908 of all grades
was 4s/13d per lb.
MARKET Conpirions.—The period under re-
view has been ono of marked changes. The
industry at the beginning of the year was still
suffering from the set-back in prices which took
place during the latter part of 1907; both stocks
and visible supplies greatly exceeded require-
ments, and there was little inclination on the
part of buyers to operate with any freedom,
During the summer, however, a gradual im-
provement was steadily taking place, and while
in February the price of Fine Hard Para had
receded to 2/9 (the lowest quotation for over
sixteen years), by the beginning of August it
stood at over 4/ per Ib,, and in the middle of
November reached 5/43, which was the highest
price recorded for more than two years.
The statistical position is now ona sounder
basis than it has been for some considerable
time past, owing not to any marked falling off in
supplies, but tothe steady and continual im-
provement intrade, which has resulted in the
absorption of surplus stocks, more especially in
America where for some months past stocks in
warehouse have been negligible.
THE POSITION OF THE PLANTATION RUBBER
InpustRY—has become more important, owing
to the increase in production, and in many in-
stances a marked improvement in preparation
of the Rubber has been readily appreciated by
buyers. Itisa gratifying fact that some sam-
ples of Plantation Rubber have been pronounced
to be equal in all respects to Fine Para, but on
the other hand, complaints as to weakness-and
variation in quality are still too numerous, and
it is evident that every effort must be made to
raise the standard quality to a higher level.
VARIETIES ON THE Marxet.--As the quantity
of Plantation Rubber produced has been in-
creasing, various new forms and methods of pre-
paration have been tried and a large number of
different varieties have consequently been put
on the market. This has led to some confusion,
and it is advisable that the number of different
forms and grades should be reduced as far as
possible consistent with proper sorting.
Biscuits, Sheet, Crepe and Scrap continue to
meet with steady support, but a noticeable
feature has been the increase in the proportion
of Crepe, owing to more estates having started
the use of machinery. Though certain buyers
continue to take Sheets and Biscuits in pre-
ference to Crepe, the demand for the latter has
_ been well maintained, and very satisfactory
prices have been paid for the more carefully
prepared samples,
202 .
The enquiry for very pale pure Rubber which
has been in evidence for some time past con-
tinues, and premiums of up to about 4d. per lb.
over ordinary Fine quality Plantation Rubber
have been readily paid for increasing quantities.
Up till now the supplies of such Rubber have
only been small, but the uses for it may still
expand considerably, and there should be room
for a largely increased supply in the future.
For all kinds of Crepe, provided preparation
has been thorough, there is a good sale, and
prices even for the lower qualities have com-
pared very favourably with those for other grades,
Propuctrion oF PLantatTion RuBBER.—From
the table below it will be seen that the total
production of Ceylon and Malaya Rubber for
1908 was about 750 tons in excess of that of the
previous year, The bulk of this increase has
been derived from Malaya, Ceylon only show-
ing a small expansion. Owing to the rather
large area of land which was put under cul-
tivation in the East during 1902-1903, we antici-
pate that a relatively greater increase in sup-
plies will be seen in 1909, while in a few years
time the production of Plantation Rubber is
likely to form an appreciable proportion of the
world’s supply.

the shipments of Amazon Rubber from Para
so far this season (i.¢., since July Jst, 1908) have
exceeded those for the same period of the pre-
vious season. This is to some extent accounted
for by the supplies having come down from the
forests more rapidly than usual, and it does
not follow that the total crop will be larger
than last season’s, whilst on the other hand,
stocks throughout the world have been materi-
ally reduced.

LEWIS AND PEAT’S REPORT.
FRoM CEYLON, THE STRAITS AND MALAY
STATES FoR 1908.
6, Mincing Lane, London, Jan. 1.
The satisfactory feature of the past year is the
marked increase in the production and imports
of Plantation Rubber, viz., 2,100 tons against
1,250 tons in 1907, and the very large increase in
the number of buyers and consumers, who now
use Plantation sorts, keenly competing for them
at the London auctions and by private treaty.
Instead of increased supplies adversely affecting
the market, consumers, who have taken to using
it, have been more and more interested in it,
from the fact that they are able now to depend
upon getting what they want regularly and in
increasing quantities, which at first with only
small supplies was a difliculty. The larger
quantities catalogued at the fortnightly sales
which averaged something like 100 tons per
month have been readily taken. The private -
business between the sales has also developed
considerably, and we now have a regular and
open market for all qualities. We may say
with confidence that now, practically all manu-
facturers, large and smai!, use Plantation Rub-
ber and are likely to do so more and more. In
consequence of the growing importance of Plan-
tation Rubber, the largest and most important
firms in the trade being best able to judge of
its preat future, have made and are makin
their arrangements to handle and deal with it
in greatly increased supplies. Production must
increase enormously during the next few years
but even now the = :
TRADE IS READY TO COPE WITH IT
whatever its dimensions. Throughout the year
fluctuations in the price of rubber have been
very great, and during the American depression
and cessation of buying, heavy stocks of all
grades including medium and wild rubber ac-
cumulated enormously; at one time the stock of
mediums alone in Europe amounted to some 10
or 12,000 tons and was for some time practically
unsaleable. With the fine para crop coming in
and being pressed for gale, the price dropped to
2/9 perlb., the lowest price touched for 10 or 12
years—and as there were scarcely any American
orders, European buyers had to take the bulk of
the pee This decline in fine para brought down
the values of plantation and of all grades—but
with a good European demand throughout and a
revival of American orders—quite

touched 5/5 per Ib. and plantation 6/, With the
greatly enhanced values of fine para and the en-
ormously increased consumption shown by the
hoavy deliveries to all parts, consumers turned
their attention to medium grades, and the whole
of the enormous accumulated stocks disappeared
and went into consumption. These facts speak
for themselves and show the very healthy state
of the rubber trade generally, notwithstanding
the constant complaints of bad trade and siack
business. Nine months ago we had enormous
stocks and low prices; today we haveexceedingly
small stocks and excellent prices aud a good de-
mand, One result of the very heavy decline in
the values early in the year of medium
rades and wild rubbers (other than para)
Baa unquestionably been to enormously decrease
the production and collection of a great many
sorts, and hence our stocks have not been re-
plenished by them, and it is very doubtful if
they will be, if supplies of Plantation are avail-
able and suftticient to meet the present largo and
ever increasing demand. It is impossible to
give any forecast as to prices in the future, but
we are of opinion that fluctuations will not be
heavy for some time to come, and we look for a
continued good demand both for Fine Para and
Plantation, a demand sufticient to take and con-
sume at satisfactory prices all that the Amazon
and Plantations are likely to send us at present.
BISCUITS
only come in small quantities now, and no doubt
this form of preparation will give way to sheets
or Crépe which are far easier to manufacture
and handle on the Estates. Tho very finest and
palest Warriapola biscuits have always sold at
fancy prices for special purposes. We have also
had good lots from Sorana, Tallagalla, Dens-
worth, Doranakande, Syston, Arapolakande and
Langsland.
SHEETS
have come in increasing quantities and a regular
standard quality has been established, making
business easier both for sellers and buyers,
Consumers can now depend upon their purchases
and get larger and increasing quantities with
but a comparatively small variation in quality
and loss in weight. In this grade, colour has
made but little difference in the price, buyers
rather going by the strength and condition, The
best known marks came from Vallambrosa and
Highlands and Lowlands Estates, and their
shipments have been most regular in quality and
of considerable size. Amongst the best stan-
dards attained we may also mention Perhentian
Tinggi, Bukit Rajah, Jugraand Deviturai. The
Penang Sugar Estates have also sent some re-
matkably good lots,
CREPE,
The bulk of the Plantation Crop now comes
in this form, and wethink it can be taken as the
most satisfactory preparation, Now that the
quality and colour is more even and the parcels
larger, buyers can repeat their orders and be
snre of what they are buying, and an order for
five or ten tons can now be executed for a single
grade with comparative ease, The quality
shipped during the year has beon excellent and
the colour has much improved, Tho very fine
203
pale, in some instances almost white, has realised
extremely high prices, and there isa large and
increasing demand for this quality for special
uses. The medium and mottled is always readily
saleable. Asto the good dark grades, there are
many new buyers constantly enquring, and
these qualities more than any other are being
used instead of the better wild rubbers, Among
the many fine marks that call for special men-
tion the following have been specially notice-
able : Jebong Crépe, which is almost white, but
no longer stands alone, as several other éstates
are now producirg quality and colour equally
good. Rosehaugh, fine thick Crépe is most
popular and one of the best preparations we get.
Damansara, Matang, Malacca, Sungei Kapar,
Pataling, Linsum, Linggi, Tarentang and Ather-
ton are all coming to the front both in the quan-
tity and quality of their shipments.
Biock.
Inthismode of preparation Lanadron Estate
still leads, and the shipments have greatly im-
proved during the year, the colour being much
paler than it was in 1907. Weare glad to notice
some nice samples from other estates quite as
good in quality, but only in very small lots as
yet. Very high prices have been paid, and
there are now iarge and regular buyers of fine
clean palish.
Woks,
Very fine pale still commands a very high price
but we regret to see that as the quantities
increase the quality as far as colour is concerned
is not as good; only a small proportion turns
out almost white as wanted. Gikiyanakande
estate still sends the bulk of this grade, but
several other éstates, including Talduwa, have
shipped some very fine though small lots,
SCRAP
—has sold extremely well throughout the
year, both in ordinary crinkly scrap form
and in brown Crépe. In Crépe form scrap cer-
tainly realises a better price; we would strongly
recommend planters to prepare it in this way,
taking care not to roll too thin which makes
it weak and brittle. Scrap Crépe should be
hard, strong and eristly,
CASTILLOA,
Only small shipments from: plantations ave
coming as yet, but the sheets from Amban-
ganga estate in Ceylon show what can be done,
and the rubber from this tree properly pre-
pared is nearly oqual in quality to ordinary
’ara sheets and biscuits. Nothing of any
note has come from Java and Sumatra so far,
and we have only received small lots from the
West Indies. The improvement in preparation
of small lots from Tobago is most gratifying,
RAMBONG
(Ficus Elastica)—is nowa most popular grade
and has realised splendid prices throughout
the year. It is most liked in Crépe form.
Some very fine lots recently realised up to 4s

demand and any quantity will be welcome,

PRODUCTION AND EXPORT OF
JAVA TEA
is undoubtedly on the increase and Java
must be reckoned with for the future as an
important factor in the world’s supply. The
figures we publish elsewhere, show an increase
during 1908 of 74 million lb, over the crop
of 1907—a 25 per cent. increase! The
monthly crop returns have shown a steady
increase, which indicates that the advance will
be permanent. Nor has the production of Java
yet reached its full capacity; A number of
estates will only return larger yields with
increasing age. Java's tea shipments to
England from ist January to 3lst December,
1908 are 12,629,513 lb. against 9,167,312 lb, for
the corresponding period of 1907. To. other
countries they have been 36,579,536 lb. against
29,288,402 |b. Holland takes 44 million half-
kilos more than in 1906, England about 1
million and Russia nearly half-a-million more
than in 1907. We commend the figures which
appear elsewhere to tho attention of ‘‘the
trade” and growers in Ceylon,

Nore.—With very large December shipments
amounting to 3,407,00) H.K., which are the
largest monthly figures on record, the total in-
crease in the Java crop for 1908 has finally
proved to be 6,630,000 H.K. or 7} million English
pounds more than in 1907.
This is an extraordinary advance to be made
in one year (a 25 per cent increase), especially
when it is considered that last year exports were
only 26,624,000 half kilos—which relatively small
figures should not allow for the large differences -
that are possible in the Calcutta exports of some
220,000,000 English pounds or the 180,000,000
pounds from Colombo,
Crops have shown steady increase during each
month of the year, which is a sure sign that the
increase will bea permanent one and that the
increased exports are not due to better con-
ditions either climatic or local, but to the natu-
ral increase from new areas of tea and froma
large number of estates which are still coming to
their full producing figures with increased age.
There seems to be an idea that the Java figures
are never made up with perfect accuracy, but
the above figures must be taken as being as
nearly correct and official as is possible under
the present conditions of shipment and custom
house returns.

RUBBER-TANNED LEATHER.
Paragraphs have appeared recently in the
press, from which it will have been gathered
that the satisfactory tanning of leather by means
of rubber, which has for many years been re-
garded as a practical impossibility, has at length
been successfully achieved, and will shortly be
undertaken on a commercial basis, It is possible
the new invention may have, at a later date,
some effect upon the raw rubber market ; that
being so, planters will naturally wish to know
what tanned rubber leather really is, what are
its uses and its claims, We are now in the
position of being able to afford full details to
our readers. The invention, we understand,
consists of a process for permeating hides
and skins with pure rubber—the result being
the substance known as Rubber-Tanned Leather
and alleged to possess qualities vastly superior
to those of the ordinary bark-tanned leather.
Increased life, resiliency, durability, toughness,
pliability, softness and water-resisting qualities
are claimed to be imparted in the rubber-tanning
process, giving a commercial value to the new
product far beyond that of any leather at pre-
sent known to the market. In the preparation
of ordinary bark-tanned leather, the cells of the
hide or skin are filled with chemicals, oils and
other substances that add considerably to its
weight; while, as is well-known, the harmful
effects produced far out-weigh any advantages
claimed for the process, a rigidity being given
to the leather which only remains so long as
itis kept dry and inno sense does it become
waterproof. In rubber-tanued leather it is ex-
plained, the effect produced is almost entirely
the reverse, the principle involved being to
effectually cleanse the pores of the skin and to
extract therefrom all toreign and superfluous
fatty matter so that the cells may become avail-
able for the absorption of the rubber, The result
is the production of a material which is practi-
cally waterproof, and which, while claimed to be
incomparably more durable than the ordinary
commercial leather, is at the same time sott
and pliable, qualities which remain some of its
distinguishing features even after immersion for
lengthened periods in water, and render it avail-
able for the manufacture of many articles for
which ordinary leather is wholly unsuitable or
unsatisfactory. We have seen the reports of
many eminent authorities on the utility of the
new process, so that the statement of the manu-
facturers may be accepted when they declare : —
“Leather so treated has been abundantly
tested and proved and is suitable for the manu-
facture of many articles cf domestic and com-
mercial use, including boots of all classes, and
particularly Army boots; mining, sluicing and
seamen’s boots, where water resistance and soft-
ness are essential ; the leather cover for spindles
in cotton manufacture; pump valves; washers ;
seat rings; covers for footballs, punching balls,
tennis balls and others ; harness including Army
harness ; saddlery ; belting and lacing for machi-
nery : portmanteaux ; solid leather trunks; gig
aprons ; leggings ; bags ; soles for use in shoeing
horses to protect the frog and for minimising the
jar on hard roads and streets; fire hose ; bicycle,
motor and Automobile tyres, in seamless and
205
jointless bands, practically unpuncturable, motor
strips on the tyres carrying the studs ; &e., &c.,
and in fact for every article to which leather is
applied. In all the articles mentioned, tough-
ness and durability, softness and water-resisting
qualities are essential, andareattained by rubber
tanning. The leather can be dyed to any
of the colours that are most used. Weight, so
detrimental to the essentials of the products, is
avoided, whilst a much greater superficial area,
weight for weight—a most important consider
ation for buyers in bulk—is obtained, rubber-
tauned leather in most cases giving almost
double area, pound for pound, as compared with
ordinary bark-tanned leather, whilst its dura-
bility is enormously increased.”
A considerable quantity of raw rubber will,
we suppose, be required for the tanning process,
Any extra demand for rubber which this may
create will, however, we fear, be more than
counteracted by the fact that if the new sub-
stance fulfils all the claims made for it, articles
manufactured from it will supplant many at pre-
sent made almost entirely from rubber. The
owners of the new process claim great saving in
cost by the use of rubber-tanned leather, Rubber
tanning, they say, though a little more costly
than chroming, is less so than bark-tanning
while the rubber-tanned product is greatly
superior to both. An important factor in the
case of rubber-tanned leather, as compared with
bark-tanned leather, is the very short period of
time required to produce the former, the result
being that there is no locking up for lengthy
periods, as in the case of bark-tanned leather, of
large amounts of capital represented by stocks
in process; while bark-tanning requires anything
from 5 to 12 months, the rubber-tanning process
occupies at the outside from 5 to 7 weeks only.
A large saving in interest on capital is thus
effected, while a much superior article, it is
claimed, is at the same time produced,
GANGARUWA RUBBER EXPERIMENT.
With regard to the rubber experiments at
Gangaruwa, all the Hevea and Castilloa trees
have been planted fifteen by fifteen. The former
were measured when 34 years old and the
girth averaged about 10 inches. The total
number of Hevea trees in the station is 1,305
which in a short time will be bringing in a
substantial revenue. There is a plot of 130
Castilloa trees on level ground, six years old
and the average girth here is 18} inches. The
gradual deterioration in the Castilloa trees
planted on the slopes as they go up was re-
marked upon, and this is illustrated by the
table, given below, supplied to our contem-
porary by Mr Lock, No. 1 row being the
bottom one, and No. 7 the topmost row. The
effect is seen in the number of trees as well
as inthe girth. They are all six years old:

A NEW INDUSTRY FOR INDIA.
In our iesue of Nov. 5th (p. 117) we stated
that it might interest those concerned to know
that a London firm was prepared to pay as much
as 12s per lb for dried sheep gut, by which is
meant the long intestine of the sheep, cleaned,
split, and dried on frames, The labour in con-
nection with this industry, we said, was believed
to be insignificant ; and we added that, as the
product required was probably often wasted in
this country, the matter seemed to be worthy of
attention, particularly so as the price offered
seemed to be quite liberal. This paragraph
attracted considerable attention in India and
Burma, as well as in some Native States. The
‘fact seems to be that hitherto, in many parts of
India, sheep gut has been wasted simply because
no market was known to exist for it, and appar-
ently no particular efforts were made to dis-
cover one. As an instance of this, it may be
here recorded, on the authority of Mr. R Burn,
IL.C.S., District Officer of Gonda, who has written
to us on the subject, that at the time the para-
graph appeared in the ‘‘ Indian Trade Journal”
sheep gut was selling in his district at from
2 pice ($d) to 1 anna 3 pies (17d) per seer of 2°06
Ib. There is reason to believe a similar state
of affairs exietsin very many other districts in
India, and more particularly perhaps in Burma.
The numerous letters we have received on
this subject show, we think, that there
are in India both readiness and ability to
engage in this particular industry ; bat
it is evident that the persons interested in
the matter have no adequate knowledge as to
how the gut should be handled and _ prepared
in order to suit the requirements of European
markets. This difficulty we shall now endea-
vour to remove ; and, what is perhaps more im-
portant, expand the scope of the industry by
the inclusion of cattle gut, cattle tail hair, and
lamb gut. Cattle gut iscomposed (a) of a long
curly gut measuring about 30 yards; (db) a
straight gut measuring 10 to 12 yards ; (c) abung
measuring from 1 to 14 yards, and (d) a throat
of weasand of about 1 yard. As regards (a), this
should be cleaned and scraped soon after the
animal is slaughtered. Itis then biown, or filled
with air, either by a _ pipe-stem blower,
or a steam blower, the ends of the gut,
of course, being tied to keep the air in.
Next it is placed over rope lines to dry in
the open. The drying process is completed
quickly inIndia. The gut is then deflated by
pricking the tied ends witha pin, and is placed
in a suitablechamber or box where a vessel con-
taining afair quantity of powdered sulphur is
kept burning for at least 12 hours. This treat-
ment renders the gut immune against moths,
etc. Itis then made up into hanks of 20 yards,
in one or two pieces; or in balls of 200 yards, and
is then packed in pressed bales containing
10,000 yards which is equivalent to 500 hanks
or 50 balls. The canvas cover should be lined
with strong tar-coated packing paper. We can
furnish the address of a London firm which is
prepared to take 50 pressed bales per month
and pay as much as £12 per bale according to
colour, width, length, strength, etc. The narrow-
The Supplement to the Tropical griculturist
er this gut is, the more value it has. As to (),
this should be scraped and cleaned as in the
case of (a), but should not be blown or dried.
On the contrary, it should be thoroughly salted,
made up into hanks of 16 yards and packed in
tierces of about 200 hanks with a sufticient
amount of salt or pickle to act as a preservative,
The market value is from 1s, to 1s. 1d. per hank
according to colour, width, strength, flaying,
length, etc., but in this case the wider the gut the
more value it has. The bungs (c) are scraped and
salted, as in the previous case, and made into
bundles of 10 pieces and shipped in tierces con—
taining an unlimited number. The value varies
from 12s, to 15s. per hundred pieces. The wea-
sand (d) is thoroughly cleaned, blown and dried
as in the case of (a), and is then packed in bales
of 50 bundles, each containing 25 pieces. The
value varies from about 8s. to 10s. per 100 pieces.
Now as to sheep gut. By this is meant the
loug cucly gut measuring about 30 yards. If
fairly wide, say about #-inch or above, it should
be scraped, cleaned and salted and then made
into bundles of 100 yards, composed of lon
strands well sprinkled with salt and pickle an
placed in air-tight tierces of about 100 bundles.
The value of this article varies from 1s. 9d. to
28, 6d. per bundle.
The wider the gut, the higher the price. [f,
however, the gut is only narrow, it should be
treated as lamb gut, which, after being cleaned
and slit openthroughout its entire eri is
placed on wooden frames and dried in the open
air. Itis then packed in hanks of about 2 lb. .
and putin tin-lined cases of 100 bundles with a
thorough sprinkling of naphthaline balls to pre-
serveit against vermin, In this case the value
varies from 7s. to 12s. per lb. according to colour,
length and strength. In the matter of sheep and
lamb gut the London firm we have referred to
is prepared to purchase all the goods of this
class that may be offered ; but dealers on the
look out for top prices should bear in mind
that special care must be taken when cleaning
the gut not to cut holes in the skin, or to affect
its strength by over-scraping.
By cattle tail hair is meant the hair clipped
off the end of the tail, washed, thoroughly dried
and packed, preferably in a hydraulic press, into
bales about 3cwt. The market value of this is
about Is. per lb. according to length, colour
and condition. A light colour is preferred.
With these particulars before them, we trust
that those interested in this special trade will
be able to supply the London market with
exactly the class of goods that is required.

A SIMPLE MOSQUITO TRAP.
ees
Mr. Lefroy of the Indian Entomological De-
partment has devised a simple and cheap mos-
quito trap, which is said to have been found
highly effective. A small box, 12 by 9 inches,
fitted with a hinged lid, is provided with a
small opening over which moves a sliding cover.
The box is lined with dark ereeu baize and
has a tin floor, The trap is placed in a shady

corner of the room, and the mosquitoes on en-
tering the house in the morning seclude them-
selves inthe box to escape the sunlight. When
duly settled the lid is shut and about a tea-
spoonful of benzine injected into the box. We
learn that in the course of a month, no less
than 2,300 mosquitoes succumbed to the benzine.
We expect to see the trap go with a boom.—

SOAP AND COCONUT OIL.
In a letter to the London Z'imes of Jan. 5th,
John Knight (Limited) of Royal Primrose Soap
Works, gives the following information :—
The price of cottonseed oil in January last
year was £22 7s 61 per ton at Hull; it has
fluctuated shghtly throughout the year, and on
December 8lst the price was £23 per ton—the
average pricefor the year being £22 10s 3d per
ton, as against an average price of £26 per ton
for 1907. Palm kernel oil, which at the begin-
ning of 1908 was worth about £26 10s per ton,
fluctuated considerably during the year until
December 3lst, when it rose to about £27 10s
per ton. Coconut oil, which at the beginning
of 1908 was worth about £28 10s per ton, has
likewise fluctuated during the year, until on
Dec. 31st, it was worth about £30 10s per ton.
Coconut oil, with a poor Ceylon crop of nuts,
may go high still.
COIR YARN, FIBRE &c.
In their annual report quoted in the London
Tumes, 15th January, Messrs. Bastone and
Firminger say:—Palmyra Fibre has taken
an irregular course during 1908, and closing
prices mark a reduction of £4 per ton com-
pared with end of 1907. At the drop the mar.
ket is quietly steady. Stock in London public
warehouses shows some increase, viz., 483 tons,
as compared with 324 tons a yearago. Bristle

GOVERNMENT STOCK GARDENS.
A New FErti.isEr.
The Dhaincha or sesbania aculeala, a new
fertilising plant, was planted at the Government
Stock Gardens a few weeks ago and has
sprouted up splendidly, The roots of these
plants become full of well-developed nodules
which when squeezed throw ovt a fluid which is ©
really protoplasmic and consist of innumer-
able bacteria, As a green manure for rice fields
this plant is said to be the best, and its intro-
duction locally should be attended with splendid
results, The mango grafts in the Gardens are
also doing splendidly. The rubber, now going
on to four years, is doing fairly well, the growth
being slow, due to the sandy soil.
Mr W Malegoda, the successful candidate
in the recent examination, is attached to the
Gardens to be trained.
CEYLON CITRCNELLA AND LEMON
GRASS OIL.
INTERESTING REFERENCES IN Messrs ScHIMMEL
& Co,’s Semi-Annuat Report.
We have received the semi-annual report
of Messrs, Schimmel & Co, of Miltitz, (near
Leipzig), London and New York covering the
period from May to October 1908. It is an
elaborate volume and as usual contains much
of interest to merchants and planters en-
gaged in the preparation and export of
Citronella, Lemongrass and other essential
oils. In the introduction reference is made to
‘‘the general depression which since the date of
our last report has made itself felt more and
more on all the World’s markets and has not
passed over our branch without leaving its im-
print behind. Hand in hand with the rapid fall
in the bank rates which occurred on every side,
and which proved sufficiently clearly a relaxation
of the spirit of enterprise in commerce, came
a gradual decline in the values of most
materials; and although the turnover during
the period covered by the present report shows
quantitatively only an immaterial falling-off as
compared with that of the previous year, it is
very probable that the financial results, in view
of the depressed prices which had almost
everywhere to be reckoned with, may here and
there to a notinconsiderable extent, fall short
of those obtained in 1907.” A speedy revival
in trade is, however, predicted, and among the
most promising signs is reckoned the gradual
‘‘healthy re-awakening of commerce and _in-
dustry in the United States.”
In the section of the report, ‘‘Commercial
notes and scientific information on essential
oils,” a good deal ofspace is devoted to Ceylon
Citronella Oil; but before referring to these
paragraphs we may quote the following re-
ference to the general state of the market :—
“Business in this important article can
only be characterised as extremely quiet and
lifeless ; the sales were small, and (as far
as old stocks are concerned) were throughout
at aloss, Under these circumstances it is not
surprising that, as already predicted in our
208
April report, the prices show no fluctuations
worth mentioning. The present quotations are
just about the same as six months ago, viz., 11 d.
cif,, and there do not appear to be at this mo-
ment any grounds from which a serious harden-
ing ot the prices for forward delivery could
be deduced.” Referring to the exports from
Ceylon, a table is given showing a con-
siderable increase, on the 1907 figures and on
this the report states: ‘‘ Although there is
no question of an increased export as com-
pared with the previous year, which might de-
press the quotations, we have yet to reckon with
the comparatively small amount of interest dis-
played in this article by the wholesale soap in-
dustry, especially in the United Kingdom, which
will also during the next few months scarcely
lead to any better position of the citronella
market.” Then follows a curious reference to
adulteration of Ceylon Citronella Oil by arrack
as follows :—‘‘ We may mention here, for curio-
sity’s sake, that the London Custom house re-
cently seized and rejected a rather large parcel,
because the oil was adulterated with alcohol.
The examination showed about 8°/. alcohol !
We may add in explanation that Ceylon
produces yearly large quantities of very cheap
arrack, and that it was here probably a question
of this adulterant. In view of the easiness with
which even smal! admixtures of alcohol can be
detected in essential oils, the export firms in
Galle will probably have no difficulty in pre-
venting the native traders who are respon-
sible for this, from continuing this practice.”
It may not be generally known, that in
Germany citronella oil has recently been ad-
mitted asa denaturing agent, and the decree of
the Prussian Treasury to this effect is quoted
verbatim. The step we note has taken on the
recommendation of the Association of Soap
Manufacturers of Berlin. Until further notice
the decree permits the denaturing of fatty oils
with Ceylon citronella oil in the quantity 200
grams to 100 kilos of the goods to be denatured.
Reference is also made to the discussion at the
February meeting of the Agricultural Society of
Ceylon on ‘‘Schimmel’s Test.” We quote fer
the benefit of those interested the folllowing :—
According to Kelway Bamber this test is in-
sufficient for judging the oils, and should be
amended. Bamber also hopes to be able to
find a satisfactory solution of the question, C
P Hayley and others, however, lay stress on
the fact that the Chamber of Commerce at
Galle has unanimously declared that the test
satisfies all practical requirements, and that
in view of the energy displayed by the buyers,
coarse adulteration is at present only rarely
met with, Moreover, the consumers are sgatis-
fied with the oil now exported. If absolutely
pure oils were wanted, it would only be neces-
sary to offer higher prices, corresponding to the
higher cost of production.
These last remarks can hardly be considered
satisfactory. In our opinion it would be more
correct if everyone endeavoured to place only
pure oils on the market, and for this reason
one must welcome Bamber’s efforts and give
them every possible support. 1tis to be hoped
that they will also have the desired effect. Our
The Supplement to the Tropical Agriculturist
own experience is that the quality of the Ceylon
citronella oils has not yet improved as much
as might be desired,
According to The Chemist and Druggist A
W Winter is reported to have stated in Ceylon
that neither pure Mahapengiri oil, nor a mix-
‘ture of the latter with Lenabatu oil will pass
Schimmel’s test ; but thisis clearly due to a
misunderstanding, as the Mahapengiri oil (Java
citronella oil) originating from Java, which is
the only one to be considered for commercial
purposes, readily and completely dissolves in
80 per cent. alcohol, and it would be very
strange indeed if the same species of grass
yielded in Ceylon a so ditHcultly soluble oil,
that it could not even pass Schimmel’s test
In the meantime the above statement has been
corrected by Samaraweera of Weligama, but
notwithstanding this we have taken steps to ob-
tain from Winter an authentic Mahapengiri
oil distilled by himself, in order to enable us
to clear up this question.
With regard to Lemongrass Oil Messrs Schim-
mel & Co. state that since their last report in
April no change worth mentioning has come
in the market quotations; the price fell to about
12d to 2d per ounce. The quantities shipped
from Cochin China from Ist Juiy, 1907, to 30th
June, L908, were about 6,082 cases against 6,239
cases in the same period 1906-7 and 2,259 cases
in the same period 1905-6. The future prospects
are not, however, gloomy. The report states :—
It is not impossible that with an im-
provement in trade generally, the price of
lemongrass oil will move upwards, for the con-
sumption of this oil is on the increase, and has
on the whole been able to keep pace with the
supplies, in spite of the depression of the last
six months. For this reason the visible stocks
have remained comparatively small. The large
imports from the West Indies which about a
year ago were accumulating in London, and
which helped to bring about the sudden drop
from about 9d in 1905-6 to 2d in 1908, are said to
be now for the greater part cleared, and will
probably not be repeated so quickly, as the pro-
ducers, at the present depressed quotations, can
no longer make both ends meet in this trade.

CLEAN WEEDING.
1. The Annual Report of the Director
of Agriculture Ff. M.S. for 1907.
2. The Cultivation of Passiflora Foe-
tida and Micania Scandens. (Circulars
and Agricultural Journal of the HK. B. G.,
Peradeniya, Vol. IV., No. 16.
We take it that agriculture may be
defined, for practical purposes, as the
art of making a profit by the cultivation
of land, and that it is the proper object
of the agriculturist to obtain the largest
possible permanent profit off a given
area of ground. In other words, agri-
culture is the art of making land as valu-
able as possible in respect of the crops
which it iscapable of growing. Itis not
the planter’s function to concern himself
with the beauty of the landscape either
by respecting the natural vegetation or
by neglecting to tap natural sources of
water power ; for example: as in other
forms of business, soin agriculture, the
question to be decided in the case of any
given proposal is, will it pay ?
Just as much asin any other agricul-
tural operation, the question of weeding,
or of weeding in a particular way, must
be decided from this point of view. The
question before us then is, does clean
weeding pay? And we think the answer
is obvious that this depends upon the
circumstances of the particular case.
We are told on all hands that clean weed-
ing is cheap weeding, and many people
seem to think that the whole philosophy
of weeding is summed up in this phrase.
But we are not prepared to agree that
even this idea might not be better ex-
pressed. Weare not surethat another
expression is not preferable—if you go in
for clean weeding at all, do it thoroughly .
If it is decided inany particular case
that clean weeding is the best policy,
then the more thoroughly it is carried
out the cheaper it will be in the long run.
Let us trace the origin of the idea of
clean weeding. It is clearly derived
from the methods of temperate agri-
culture, and is particularly applicable
to the case of annual crops. Where any
kind of an annual cropis grown it un-
questionably pays to keep theland clean,
If weeds are allowed to seed or spread in
any quantity, trouble rapidly multiplies
itself. We might almost say that agri-
culture in the strictest sense, that is to
say field cultivation, consists in the first
instance in the extermination of weeds.
We think it may be taken as generally
agreed that, in the case of short-lived
crops, weeding cannot be carried out too
thoroughly.
When one comes to consider the
question of crops which are to occupy
the ground permanently, or for a con-
siderable number of years, the question
of what will pay best is not so immedi
ately obvious. We require to proceed
somewhat cautiously when we find that
men of considerable experience hold
210
apparently diametrically opposite views
with regard to the question of clean
weeding as applied to the ease of per-
manent tropical crops.
Let us go back for a moment to home
experience. We find that fruit trees at
home are grown in one of two ways.
Orchards are either laid down in grass,
or they are combined with the cultiva-
tion of vegetables. Where fruit trees
are grown by themselves and without a
catch-crop of any kind, weeding is only
resorted to in cases where large tracts
of level land can be dealt with by means
of machinery, as is done in parts of the
U.S. A. Weeding by hand is certainly
never dreamt of.
Returning to the consideration of
tropical products. It is clear that the
same rule applies as at home to crops
which only occupy the ground for a few
months. Grains and vegetables, cotton,
tobacco and other annual crops require
cultivation and the thorough extermin-
ation of weeds. But when we pass on to
the consideration of more permanent
crops like tea and cacao, we find that a
number of separate points have to be
taken into consideration. In the case of
every such crop the question of the
growth of leguminous plants age a source
of nitrogen and organic matter and the
question of forking or other methods of
cultivation have to be considered in
their relation to the process of weeding
proper. But more than this, weeding
on tea estates is a problem intimately
bound up with the question of the
management of labour. and that is a
problem upon which we do not propose
to intrude upon the present occasion.
The controversy over weeding relates
chiefly to rubber, and itis to the ques-
tion of clean weeding rubber that we
propose to devote our attention just
now. Here, again, the question of weed-
ing cannot be considered without at the
same time taking account of the kindred
processes of tillage and the growth of
leguminous crops.
The question of catch crops, too, de-
mands attention. And there can be no
doubt that the growth of a suitable
catch crop under conditions of thorough
weeding and cultivation is a process
which will pay ifasuitable crop can be
found, and if it can be disposed of at a
profit when grown. Unfortunately
these conditions are not always realis-
able in Ceylon.
Apart from the question of catch crops,
does it pay to clean-weed a plantation
consisting simply of rubber? In the
face of the assurance of such authorities
as Mr. Carruthers and Mr. Kelway Bam-
(MARCH, 1909.
ber that in most cases it’does not, it may
appear superfluous to discuss the matter
any further. But, on the other hand,
many experienced planters tell us that
we must clean-weed, and besides we are
anxious to thresh the matter out for
ourselves.
We feel bound to giveitas our own
impression that, where rubber is planted
on level ground and stumps can be got
rid of within practicable limits of cost, it
will pay tocultivate and weed a rubber
estate with modern machinery. But it
is no doubt the case that on a majority
of estates, owing to the nature of the
ground, the size of stumps and general
monetary considerations, such a method
will be found impracticable.
Itis the contention of Messrs, Bamber
and Carruthers that rubber can be
grown with hardly any diminution in
size, and at a much smaller cost as com-
pared with clean weeding, by a pro-
cess which consists essentially in the
growth and encouragement of selected
weeds. The method consists in weeding
only a narrow strip down each row of
trees, and encouraging between the rows
the growth of some creeping plant
which will smother and eventually kill
all other forms of vegetation.
A point upon which Mr. Bamber lays
special stress is the use of the green
creepers themselves as a mulch to be
applied round the bases of the rubber
trees, Here, again, we see the impossi-
bility of regarding the weeding question
asa thing by itself, the advantages and
disadvantages of removing weeds must
be considered in connection with other
Operations not strictly comprised under
the head of weeding.
In the ‘report and circular before us
various advantages are claimed, and we
think with justice, for this method of
dealing with weeds. The creepers speci-
ally recommended for this purpose in
Ceylon are the wild passion flower—
Passiflora fotida and Mikania scan-
dens. The latter might recently have
been observed in the act of demonstrat-
ing its powers of smothering other
vegetation to a marked degree by anyone
travelling up or down the railway _ be-
tween Kandy and Polgahawela; and the
former is also abundant, though less
rampant, in the neighbourhood of Pera-
deniya, Extracts from Mr. Carruthers’
repcrt will be found on a later page
of the present issue of the 7.A., and
Mr. Bamber’s circular has recently been
published by the Royal Botanic Gar-
dens Department. Wemay leave them
to tell their own story, confidently re-
commending both these essays to all
who are interested in the planting of

GUMS, RESINS, SAPS AND EXUDATIONS.,
IS CLEAN WEEDING ADVISABLE?
(Extract from the Report of the Director
of Agriculture, F.M.S., for the year 1907).
The remarks in my last report as to
the value of a green manure plant, of
which I gave examples, in the place of
the general habit of regularly scraping
off weeds and allowing the sun and rain
free access to the soil, had little or no
effect at that time, but the desire to cut
down expenses has caused the sugges-
tion to be reconsidered.
Weeding on most of the rubber estates
inthe Federated Malay States is the
item costing most annually. This sum
isspent on labour, and represents in
many cases 70 per cent. or more of the
total labour of the estate.
The object of the rubber planter is to
obtain as quickly as he can vigorous
trees of as large agirthas possible, at
the smallest cost, and in order to effect
this he keeps his fields as clear of weeds
as possible and so allows the rubber tree
to have all the moisture and _ plant-food
available in the soil.
That clean weeding will show a better
result in the growth of the rubber trees
than allowing all and any weeds to grow
continuously, can no doubt be proved.
In Perak, however, some of the estates,
from want of money or shortness of
labour, have not been able to keep their
plantations clear of weeds and have
abandoned weeding. In some cases the
weeds are checked by being regularly
cut, but in others nothing at all has been
done to eradicate or discourage the
weeds.
The growth of trees on such places is
somewhat poorer than trees in similar
conditions which have been kept free
from weeds, but the vigour and girth of
trees where the weeds have been allowed
to grow is not so markedly different as
the disciples of clean weeding would
expect to see.
. The belief in clean weeding is a tradi-
tion handed down from English farming
to tea and coffee planting in the Hast ;
good farming is associated with absence
of weeds. In Europe, the farmer of
cereals and other crops does not practise
the method of using certain plants as a
substitute for weeds. There are various
reasons why clean weeding in such crops
is a good policyin Europe, but annual
crops have to be treated differently
from permanent cultivations, and the
conditions of labour, cultivation, plant
growth and especially climate are
entirely different in the tropics from
those in temperate climates and conse-
quently methods have to be modified.
The objections to clean weeding in
rubber cultivation in the Kederated
Malay States and removal of all protec-
tion from the surface of the soil, are
that it allows a large amount of percola-
tion, of heat radiation and of evapor-
ation of moisture, also that heavy rainfall
on all but flat surfaces always results in
the constant removal of very large quan-
tities of top soil, which are either carried
away in streams or transferred to the
drains, Itis not easy to estimate the
loss that takes place in tropical climates
where soils are allowed to remain ex-
posed and frequently scraped. An im-
mense amount of plant-food is continu-
ally also lost through percolation and
drainage; the greater part of this is
absorbed by the roots of any plants
growing on the surface, and when the
leaves and stems of these plants are cut
this is to a great extent returned to
the soil.
With the soil protected from the rays
of the sun the conditions of moisture
and temperature are most favourable to
the development of bacteria which are
responsible fur the liberation of plant
food. Infclean-weeded land the top two
inches or more of soil are, because of
admission of heat and light, made impos-
sible for feeding roots and the prepar-
ation of food forthem. When the ground
is covered this surface layer is kept
moist and useful for the feeding roots.
A considerable area is thus added to the
area of soil available for rubber roots
and the growth of the trees is improved,
In addition to arguments for clean
weeding there is a local one, the danger
of the ground being taken possession of
by ‘‘lalang” (imperata arundinacea), a
pestilent weed, which once allowed to
invade a plantation can only be eradi-
cated at enormous expense. This plant
is ubiquitous, is always one of the first
to cover newly-opened land, and by far
the most difficult weed to eradicate,
The experience gained in the use of
tapioca as a catch crop in rubber, which
obtains on some thousands of acres of
rubber showing excellent growth, is
another argument in favour of keeping
the soil covered up. Few, if any, crops
take more from the soil than tapioca,
but this loss of valuable plant-food in
the soil is to a great extent compensated
Gums, Resins,
for by the advantage of keeping. the
soil from the sun and rain. The girths
of young rubber trees grown with
tapioca is in many cases as large as those
of trees in similar land, clean weeded,
and without any other crops.
The position thus is: Clean weeding is
a costly process, which ensures quick
growth ot young rubber trees and pre-
vents the land being taken possession of
by undesirable weeds. On undulating
land it causes loss of top soil, and on all
land it means loss of moisture in the
surface layers of the soil.
Rubber plants usually grow better in
clean than in weed-covered land, because
the plant-food and water present in the
soil is all available for the rubber and is
not used by the roots of various other
plants which are useless to the planter.
The high cost of weeding and the fact
that, with a not too abundant supply of
labour, the majority of coolies are
employed at this work, both point to
the desirability of some other method
not less helpful to the growth of young
rubber, if such can be found.
Though figures of cost of weeding vary
very greatly, on some estates the cost
two years after the land has been
opened is not under $2 per acre per
month, or $24 per year, This represents
on an estate of 1,000 acresa cost of
$24,000 per year, and a probable cost for
weeding of nearly $100,000 before the
rubber is in bearing.
In labour it represents a continual
force of about 250 coolies working for
3800 days in the year.
I have for the last three years been
investigating the question of asubsti-
tute for weeds which will reduce the
wage bill without reducing the rapidity
with which the rubber trees grow, and
mentioned in my annual report for last
year three plants which observation and
experiment show to be suitable and
therefore worth a serious trial on every
estate.
These three plants belong to the order
Leguminos, the clover, pea and crota-
loria tribe,a group of plants many of
which are characterised by the posses-
sion of bacteria on their roots. These
bacteria, the life history of which has
been investigated fully by a large
number of botanists and agriculturists,
live in what is technically called sym-
biotic relationship—7.e., both host plant
and bacterium being of mutual service
to each other. In a report of this
character itis unnecessary to more fully
explain this point, but it will suffice to
say that the bacteria which form charac-
teristic nodules on the roots of the host
“ie
212 [Marcu, 1909.
plant, take nitrogen from the air, and
this nitrogen is afterwards available
in the soil as plant-food. The amount
of nitrogen thus added to the soil
varies with the species of the bacteria
and their numbers, but in the case of
one of the plants hereafter mentioned
experiments have shown it to be as
much as 200lbs. per acre per year.
Leguminous plants which possess these
bacteria may therefore be considered
as friends and not as foes, as_ useful
plants and not as weeds in a rubber
plantation.
In order to get the maximum of benefit
from these plants it is necessary to cut
them down periodically and leave them
lying on the ground. Thelength of time
they should be allowed to grow depends
on the vigour of the plant, in most cases
about nine months.
This cutting down need not be an ex-
pensive operation, as it is not intended
to eradicate the plant, but only to allow
the green parts to form amulch on the
surface of the land and thus return
something to the soil.
The operations of weeding must, as the
planter knows to his cost, be carried on
periodically and not be delayed, or the
weeds will get out of hand, and the cost
of eradication be very greatly increased
or made well nigh impossible, but the
cutting or hacking down the leguminous
green manure plants may be postponed
without danger until such time as labour
is available for the purpose.
The three plants which seem to me
most suitable in Malaya for the purpose
above mentioned are: Crotalaria striata,
Mimosa pudica and Desmodium trifto-
rum.
Crotalaria striata is a quick-growing
vetch-like plant with trifoliate darkish
green leaves. In good soil with sufficient
rainfall it grows to a height of 6 feet in
about a year. When sown sufficiently
thick it completely covers the ground
within a few weeks, so that the clearing
is like a good lucerne or vetch crop in
Europe, and the surface of the ground is
not seen at all.
It has been proved by experiments
with this plant in Ceylon that 14,000 Ibs.
of organic matter were formed by crota-
laria under cacao, and the nitrogen in
this organic matter was equal to that in
1,7000 lbs. of castor cake or 700 lbs. of
nitrate of soda. Other plants—weeds
—cannot get enough light under the
dense cover of the crotalaria, and new
weeds are kept out as their seeds cannot
reach the ground which is so _ well
covered. If the crotalaria is sown in
good growing weather, and if the land is
clear of all weeds, no further weeding
:
’
“
:
Marcu, 1909. j
should be necessary, but in the case of
land which is thoroughly permeated
with the underground stems of lalang
or with the roots of other weeds it
may be found that during the first two
or three months weeding is necessary.
The crotalaria seed is sown broadcast.
As to the quantity to be used per acre it
is better to sow more than is necessary
than to leave bare patches where weeds
ean thrive. Mr. Lauder Watson, who is
the first Federated Malay States planter
to use this plant in rubber planting,
informs me that on Lauderdale, where
photograph of crotalaria was taken,
he used about 7lbs. I have seen good
results from using only 4 lbs. per acre,
Mimosa pudica, the ‘‘ sensitive plant,’
which was another of the plants sug-
gested in the last annual report, is in
many ways the best of all plants to put
down as a substitute for weeding. In
many cases it has taken less trouble to
establish this plant than ecrotalaria, and
it thrives extremely well in the Malayan
Peninsula on varying soils. ‘I'he peculiar
habit of shutting up its leaves when
touched is in its favour. When rain
falls at all heavily the leaves shut and
the water reaches the soil at once, but
when the sun shines again the leaves
open up and protect the soil from its
rays.
My experience of this plant is_ that
while it grows well on sloping and dry
land it seems to enjoy more moist
conditions and can be seen in great
vigour in ravines and flat places where
the moisture is more abundant.
Desmodium triflorum, asmall creeping
shamrock-like clover, has the advantage
that it grows only a few inches high and
covers the ground with a turf easy
and pleasant to walk on. It is, however,
more difficult to establish, and as it seeds
very sparingly, it is not easy to obtain
any quantity of seed for planting. On
one estate some two hundred acres has
been successfully laid down with this
plant by taking it from neighbouring
waste land and planting it as soon as
the land was cleared.
The question of the best method of
establishing one or other of the substi-
tutes for weeds or clean weeding is being
experimented on both at the Experi-
ment Plantations of this department
and by various planters who are alive
to the great advantages to be gained
if they can cover their ground with a
friendly plant. By far the best time
to establish one of these plants at a
minimum costis directly the land has
been burnt off. In virgin land after
burning no seeds of herbaceous plants
are alive in the soil, and any seeds sown
215
Saps and Exudations.
or plants planted have no competitors
and quickly take possession of the soil.
Having once got the plant established
all the danger of lalang or other weeds
gaining an entrance, and the immediate
necessity of putting rubber in is over,
since the fields do not get any worse,
but rather better for the reception of
the rubber plants; and the cost of cut-
ting away the crotalaria, mimosa or
other plants to putin lines and holes is
very little. Drains are not necessary or
even useful, and thus another expense
is saved. The only weeding necessary is
in case jungle trees or shrubs sprout, and
these can easily be noticed among the
prevalent growth of a single plant and
removed. No_ soil is lost from the
beginning of the opening of the land,
aud the gain in this to the roots of the
ruober plant is not to be neglected.
The chief arguments, and they are -
many and constant, against the adop-
tion or even the trial of the abandon-
ment of weeding in tavour of a green
mabure are: That it has never been
done in rubber or in other’ tropical
products, an argument which is always
used to disccurage any new departure.
That the plants suggested will take
possession of the land to the exclusion
of other plants—weeds. This can be
met by an appeal to experimental piots,
and as far as I have observed where
care is taken and money spent, even
in two or three-year-old clearings, these
plants can be establishedina short time.
It must be remembered that even if
30 per cent. of the surface of the land
is covered by harmful weeds, and the
rest by one selected plant, it is probable
that the rubber will grow more vigor-
ously than in clean weeded fields, and
with no cost for weeding.
That the thorns on the Mimosa will be
a nuisance’ to coolies getting about the
estate. This argument is used without
considering that by putting in green
manure, the number of coolies whose
work will take them. into the field is
very small and their legs can be pro-
tected. The only reason why coolies
are needed ina field properly covered
by the green manure is to search
for white ants and to put in any
supplies; the latter work will very
probably be lessened by the fact that the
shaded ground gives very much better
conditions for the growth of the young
rubber plants than its exposure to sun
and rain.
That the appearance of an _ estate
would be against it in the eyes of a
valuer, The answer to this is that when
the valuer or retired planter, to whose
Gums Resins,
mind such methods are worse than
sacrilege, sees that the growth of the
trees is as good as before,and remembers
the money that has been saved, he will
no longer consider bare soil the acme of
zood planting.
The chief argument thatI have per-
sonally met with among planters is
“Yes, if you could convince my ‘V.A.’
or my Directors, but unless they are
convinced I am _ powerless,” but this
difficulty can be removed by the planter
clearly showing by measurement of trees
and tigures of decrease of cost-on a small
plot that the method is correct. Itis
difficult to remove fixed and long stand-
ing views as to tropical cultivation from
the minds of men who have experience,
but the stern tacts of dollars and cents
saved without diminution of vigour in
the rubber trees when shown will
convert.
Before leaving this question I may be
allowed to quote from Dr. E. B. Vorkee’s
recent work on agriculture published
during last year.
This is written in regard to American
agriculture, where the conditions are
not so unfavourable for clean weeding
as in tropical countries with a heavy
rainfall.
“¢ To keep the land constantly occupied
with growing plants is particularly im-
portant, both in the hot summer and in
fall and spring. The covering of the
land in summer prevents the temper-
ature rising so high as to destroy the
organisms iu the soil, while the covering
in fall and spring prevents the mechani-
cal losses that occur from wind and rain
and by the carrying away of food in the
soil water.”
Dr. Alfred Russel Wallace, whose
name will always be associated with
Malayan regions, writes to me in regard
to the protective forest belts which
have been, and are being, laid out
through the Federated Malay States:
“They prevent the loss of soil which can
never be replaced.” The italics are Dr.
Wallace’s. Thisis also true of the soil
lost by clean weeding.
On some estates there are growing
among the weeds leguminous plants
which possess nitrogenous nodules on
their roots, and it may be possible in
these cases for coolies to be shown how
to leave these plants in weeding, so that
ina short time they may get entire
possession of the field and weeding may
be discontinued. Leguminous plants can
often be recognised by those unacquaint-
ed with botany, their leaves being
divided, and in appearance like those
of the vetch, pea, mimosa, cassia or
crotalaria,
214
[MarcH, 1909.
As the chief cost of an estate until its
profit-earning period is that of weeding,
any suggestion as to the reduction ot
that prime expense should meet with
consideration.
If every estate would set apart a
portion of their newly-opened clearings
for an experiment with a green manure,
keeping a record of the cost of putting
the land into Crotalaria, Mimosa,
Desmodium and whatever other useful
plant is selected, and recording the
money spent on adjoining land cultivated
on the existing clean-weeding method,
and carefully measuring the trees on
each place to see the relative progress,
I have little doubt that the benefit of
keeping the soil covered, instead of
constantly scraping off the weeds, will
be seen.
That the planter should adopt sugges-
tions made by scientific experts without
weighing them carefully is not to be
expected, but what is wanted is that
each practical man should satisfy himself
by careful trial that this proposal in
regard to cultivation of rubber estates
is feasible.
Even if this experiment results ira
loss of money and the destruction of a
few acres of rubber he cannot be blamed
in making it, considering the large
economy thatis to be effected if it is
proved to be successful.
WEED KILLING BY SPRAYING.
The experiments in regard to the
eradication of lalang and other weeds
by means of spraying with a solution
of arsenite of soda were carried on
both by the department and by several
planters with encouraging success.
The difficulties in regard to the pro-
hibitive cost which was charged locally
has been to some extent overcome, and
supplies of this substance were obtained
from Calcutta at one-fifth of that charged
in the Federated Malay States.
This cost is, however, too great ; it can
be obtainedin England at a cost, in-
cluding freight to Port Swettenham, at
about 12 cents perlb. Asthe chief cost
in this method of destroying weeds is
the cost of the material used in the
spray, it is mostimportant to obtain the
arsenite of soda as cheaply as possible.
The difficulty in regard to sprayers has
also been toa great extent overcome,
and though itis not yet possible to get
suitable sprayers locally, yet some
English and American machines at
varying prices from $1 for hand sprayers
to $250 for steam power have been in-
vestigated and shown to be suitable to
the purpose.
~Marcu, 1909.]
While the use of arsenite of soda was
first investigated, as mentioned in my
last report for the eradication of the
most pestilent weed, lalang (/mperata
arundinacea), this method of getting rid
of weeds is still more efficacious in the
ease of other weeds submitting a larger
and flatter surface to the spray. The
leaves are all killed within 48 hours, and
should be left to rot onthe ground and
not pulled out or scraped away; by
this means the soil is protected from
rain and sun, andif the plant becomes
green it can be again sprayed. The cost
of this method of destroying weeds
necessarily varies with the character of
the fields to be sprayed, but in most
eases with hand atomiser sprayers the
cost should not be 50 cents per acre
where very weedy, and on ordinary
fields probably not more than 10-15 cents.
A series of experiments near the labora-
tories of the department are in progress
to estimate the cost of eradicating lalang
by the following processes :—
1. Spraying with arsenite of soda;
2. Digging and picking out all roots
3 ne re-chungkoling ;
4. The introduction of Passiflora
foetida, ‘‘ wild passion flower,” a
vigorous creeping plant which
smothers lalang and can itself be
easily removed.
These are being carried out in various
ways on some ten l-acre lots and the
exact cost in each case recorded. The
lalang, which has been in possession of
the fields for some years, is tall and
vigorous, typical of thousands of acres
which are to be found throughout the
Peninsula.
HINTS ON PLANTING CASTILLOA.
By F. G. Scott.
On ordinary Cacao soils Casli/loa elas-
tica should be planted about 20 ft. apart,
and on very rich soils about 30 ft.
When possible, holes should be prepared
in March, about 8 feet deep aud 2 feet
wide, and filled with equal quantities of
earth and stable manure which would
help the young plants to become quickly
established. They should be putin about
three months after preparation of the
holes so as to allow the earth to settle,
which would be in June, the beginning
of the rainy season when the field has
received one or two showers, for if plant-
ed later it might become too saturated
and would tend to rot the young root-
lets, consequently killing the plants,
which is often the case when forming
215 Saps and Hxudations.
estates. If the plants are in bamboo
pots it should be always removed as it
allows the plant to spread its roots much
quicker. The best way to remove the
pot is to take hold of it in the left
hand anda cutlass in the right; allow
it to be at right angles to your body, the
plant facing you, and give three fairly
quick sharp blows with the cutlass so
as to strike it in a different place each
time; then remove the three broken
pieces together with the small gravel at
the bottom of the ball, taking care that
the earth does not break up.
Castilloa elastica grows best under
partial shade, and would thrive well
along the boundaries of a cacao estate,
provided they are planted at proper dis-
tances and not intended as wind-breaks.
Where trees are exposed to wind
‘Funtumia elastica could be planted
with advantage, not only as a wind-
break but as a rubber-producing plant.—

CAMPHOR AND ITS BY-PRODUCTS.
DISTRIBUTION OF CAMPHOR TREES.
The growth of this important tree is
limited in Japan to the south of 36° north
latitude. On the south coast of the Main
Island, Shikoku, and Kyushu, the trees
are met with only in the compounds of
shrines or temples, or in gardeus, where
they have been preserved from felling.
As the distillation of camphor became
common, the felling of the trees in-
creased, and forests of this valuable trees
were greatly reduced in area, but a few
old specimens were fortunately pre-
served.
The propagation of this tree is in no
way neglected, so that the production of
camphor will increase in the course of
years. Formosa has at present an exten-
sive supply of these trees, as there, in
districts not yet explored, huge trees are
still found in their primordial luxuri-
ance,
CAMPHOR-TREE PLANTING.
In raising camphor trees, seedlings
are obtained by sowing the seeds
directly in a wood. Small holes are
dug in an already well-grown forest
of evergreen oaks or red pines, and
four or five seeds are put in each
hole. The shelter of the trees favours
the growth of the seedlings,
In fifty years trees so planted will
attain a diameter of one foot when
they are large enough for the produc-
tion of camphor. In many places
attempts have been made to grow

the tree by transplantation, but with-
out suecess, In other places, in order
to obtuin leaves to produce camphor,
the so-called ‘‘ coppice-planting” is
practised, and it will be of advantage
to this industry.
CHEMICAL PROPERTIES OF CAMPHOR.
Every part of a camphor tree contains
camphor, which is obtained by dis-
tillation. Camphor is a white semi-
transparent amorphous substance with
a specific gravity of 0°987, and with
a peculiar smell. Whenit is tasted it
gives a sharp flavour, turning into a
cool one. When plunged into water
it forms circles, and when lighted it
burns, floating on water. It is almost
insolub.e in water, but readily dis-
solves in alcohol, ether, acetone,
chlorotorm, acid, and volatile oil.
Camphor is found as crystals in the
tissue of the woud, and by double distil-
lation is separated from the crude oil,
the product of the first distillation. It
is an oxidized product of camphor-
genotol, which forms the principal of the
camphor oils of commerce.
CRUDE CAMPHOR.—This substance is
obtained as crystals by the distillation
of camphor chips or camphor leaves in
the presence of water vapour. It is
separated as such after sufficient distil-
lation, and subsequent liberation of
water and oil. It is adark-coloured sub-
stance, and fuses at 170° C.
CrupE CAMPHOR O1L.—This substance
is obtained as a liquid in the separation
of camphor, with which it comes out
simultaneously. Camphor and other by-
products are afterwards separated fiom
this substance.
WHITE O1L.—This is a white oil with
a specific gravity of 088 at 15°C.,
obtained by sublimating crude camphor
oil. It distills below 188° C., and is used
in soap-making, &c.
ReEpD O1n.—This substance, like white
oil, is obtained from crude camphor oil.
It has a specific gravity of 1°020 at 15°
C., and fuses at 170° C.
Biack O1L.—This substance also is

LAC IN THE EASTERN DUN, U. P.
By G. N. GRAHAM YOUNG.
The life history of the insect is now
well known, but there are some facts I
would place on record gleaned from in-
vestigations made personally in the
Eastern Dua,
* One Yen = 2s. 04d.
MARCH, 1909. |
In this locality there are two broods,
and the lac is collected during the first
half of July and from the last week of
October to the end of the first of
November. The young swarm generally
by the end of the second week of July
and of the first week in November, but
the time of swarming varies consider-
ably in different seasons. A good deal
depends onthe weather, fora normal
season the broods swarm during the
periods mentioned above, but should
the season bea dry one, and the rain
hold off, theswarming will be delayed.
About six weeks to two months after
swarming the males appear, but they
are few in number in proportion to the
females, so that in order to fertilise
every cel], each ¢ must be able to im-
pregnate 1009. Males without wings
are to be seen in both broods, but they
are scarce in proportion to the winged
forms. Itis erroneous to contend that
one brood is winged while the other is
not.
The cells are attended by several
species of ants, some of large size, and
these swarm over the branches in
myriads, but appear to do absolutely no
damage to the insects. On thecontrary
they afford the cells a considerable
amount of protection by attacking and
driving off any insects that happen to
alight on the branches. Asa proof of
my statement I would ask the reader to
grasp atwig containing lac and note
the behaviour of the ants. I think he
would not care to repeat the experiment.
It would serve no good purpose to
attract the ants from the trees by
placing something more toothsome at
the roots, and the cost would probably
take away all the profit. The presence
of antsis an indication that the lac is
healthy, and vice versa.
The pests most to be feared are moths,
and ot these I have noticed species
Gal:ria and Enblema. The larvee of
these are to be found in both broods and
practically all the year round, There
appear to be several generations of
these moths in the year, for I have
found larve in several stages of develop-
ment as well as pupe in a single stick
of the lac and at different times of the
year. Inthe first week of April I got a
group of twelve white eggs, which were
laid on the side of my rearing jar by a
Enblema sp. moth which issued in the
third week of March. A new species of
Ichneumon fly has been reared from
infested lacand has been sent to England
to be named. This fly, it is hoped, is
parasitic on the Enblema sp. The
damage done by these moths is very

considerable, and 1 have known them to
entirely destroy the cells on a tree.
These moth pests are certainly on the
increase, and given favourable con-
ditions they may entirely destroy the
lac in aforest. The next greatest enemy
to lae is frost, In the Dun lac is pro-
duced entirely on B. frondosa which is
badly affected by frost, and almost all
the tender twigs are killed by it
during the winter, so that only one
good crop can be expected annually.
Fire does a great deal of damage,
if the area is not carefully pro-
tected. Wind may do serious damage
at the time of swarming, and violent
wind is always harmful] ; a gentle breeze
though greatly helpsin the spreading
of the young from tree totree. Inthe
ease of drought, the insects may be
killed at the time of swarming. Monkeys
do not, as is supposed, eat the lac, but
if they are watched it will be noticed
that the damage done is only out of
curiosity and wanton mischief,
At Pathri in the Saharanpur district
there isa large forest area which is
composed almost entirely of B. frondosa,
which would yielda large quantity of
‘lac were ittaken in hand. Some experi-
ments have lately been carried out
by private individuals, but owing to
the adverse conditions made by the
Forest Department they have been
compelled to abandon the experiments.
One of the conditions laid down was
that grazing be allowed, and this re-
sulted in the forest being burnt and
entailed a heavy loss on the experi-
menter.
Brood lac should be cut from the trees
about a week before the swarming
begins. In order to fix on the correct
time itis only necessary to break open
afew cells and examine them with an
ordinary magnifying glass, when if the
young can beclearly seen and if the
colouring matter has become of the
consistency of treacle, they are within a
week of swarming.
When infesting trees, say, of an
average height of 25 feet and well
branched, itis sufficient to apply 4 lbs.
of brood to each tree. The brood should
be tied lightly in bundles, each bundle
to contain three sticks, about a foot
long. These bundles should be tied on
the upper surfaces of the branches, and
about three-fourths the way up and
near the tender twigs. Itis not of any
advantage to use straw with the bundles,
but care should be taken that the sticks
of brood lac lie along the upper surfaces
of the branches to which they are tied.
The bundies of brood should be fixed by
a tie at either end and not in the middle,
Gums, Resins,
The lac froma Ficus sp. have been
_known to take splendidly on B. frondosa ;
and the B.frondosa lac young have
been carried by the wind to the garden
lichi tree and thrived so well as to
necessitate the infested branches being
cut in order to save the fruit.

OILS AND FATS.
THE CASTOR-OIL PLANT.
(Ricinus communis, L.)
By HAROLD CUZNER,
Bureau of Agriculture.
The castor-oil plant (tangan-tangan,
Tagalog), the seeds of which furnish the
castor-oil of commerce, is probably a
native of Africa, although it is found
growing wild in many tropical countries.
It has been so long in cultivation that
nothing is accurately known as to its
original habits. Long before the Chris-
tian era it was cultivated in India, and
its medicinal properties were known.
Its seeds have been found in ancient
Egyptian tombs, and its cultivation is
described in the writings of the Romans.
In Europe it was cultivated by Albertus
Magnus, Bishop of Ratisbon, in the
middle of the thirteenth century, and it
was known as a garden plant in the
time of 'Turner (1568), who mentions the
oil as ‘‘oleum cicimum vei ricinum.”
At the close of the same century
Gerardi was familiar with this plant
under the name of ‘‘ricinus” or ‘“ kili,”
the oil of which, he states, was used in
the treatment of diseases of the skin.
After this the plant seems to have fallen
into complete neglect, in 1761 the seeds
being rarely found in druggists’ shops
and the oil scarcely known. In 1764 it
was again brought to notice by Peter
Cavinano, a physician who had practised
for some time in the West Indies, in an
article entitled, ‘*Dissetration on the
Oleum Palmz _ Christi, sive Oleum
Ricini,” in which he recommended it as
a purgative.
The seeds were admitted to the Lon-
don Pharmacopeeia in 1788, and direc-
tions given for preparing the oil. At
this period and tor many years there-
after the small supply of oil required in
Europe was obtained from Jamaica, but
it has gradually been displaced of late
years by the product of the East Indies
and India, where, it is stated, 830,000
acres were devoted to the growing of
the bean in 1890.
The plant is also cultivated in Africa,
Italy, Central and South America, and
China, and in the United States in
Kansas, Oklahoma, Wisconsin, Oregan,
and California. In these Islands it is
not cultivated, but has grown wild in
all parts of the Archipelago, and in
some sections of Negros and Midanao is
Tear ae to be taking possession of the
and,
There are two forms of the plant, 2.e.,
the large and small-seeded varieties.
The large-seeded varieties give a rather
large amount of inferior oil, which is’
used for lubricating, ete., while from
the small-seeded varieties the medicinal
oil is obtained.
Kurz states that the plant yields a
white resin, but as no other writer
alludes to this it may be said not to
exist in any quantity worth considering.
Aside from its use as an oil plant, its
principal value is as a food for the “eri”
silkworm in Assam, though itis stated
that paper pulp may be made from the
stems and bark.
The seeds yield, on the average, from
46 to 53 per cent. of oil, though there
are occasional records of 60 per cent.
It is a thick, viscid oil, with a specific
gravity of about 0:964, The pharmaceu-
tical product is almost colourless,
while the inferior grades are of a
greenish-yellow hue. The odour and
taste vary from the nearly odourless and
tasteless oils of the better grades to the
nauseating ones of the poorer grades.
It is used for dressing leather, for
lubricating, and, in India, to some
extent for lighting purposes. Soap
anda mordant for Turkey red dye are
also made from the oil.
The oil saponifies easily with caustic
soda and yield aclear, soluble product
which is used in the manufacture of
the cheaper grades of transparent soap.
However, itis not likely to be looked
upon with much favour for this pur-
pose, asit has a tendency to become
rancid in keeping, and owing to its
being extremely soluble, as stated above,
it is very wasteful.
The mordant for the Turkey red
dye is made by treating the oil with
sulphuric acid in the proportion of
four parts of oil to. one of acid, It
should be stirred continually until
thoroughly mixed, to avoid a rise in’
temperature; then allowed to stand
twenty-four hours and washed to get
rid of any fatty acids.

India for the years 1885-1887 is given

On the day after feeding, the temper-

of milk fell off from 11 to 5 liters per
day. The animal recovered in ten days,
when a second feeding was given, with
seed coat in the meal.
While there is no doubt that the
cake contains good fertilizer material,
it has been found to be a more ex-
pensive source of nitrogen than cotton
seed cake, as is shown in the report
of the Connecticut Experiment Station
for 1897:—

Two hundred pounds of nitrogen

$840 more than the same amount in
cotton-seed meal, so that the net
profit, provided the quality of the
crop were the same, would have been
$5°47, but this was not the case.
Another use that is sometimes made
of the cake in India is for making gas
to illuminate the railway stations.
CULTIVATION.
The method of cultivation followed
in Madras, outlined in a circular of
the Royal Botanic Gardens, Ceylon, is
probably as good asany. There the land
is ploughed twice after rain, and the seed
dropped in the furrow and covered by
the plough following. A month later,
when the plants are a foot high, the
land between the rows, which are a
yard apart, is ploughed again. The crop
of beans is often followed by either pea-
nuts or corn.
The only improvement to be suggested
on this method is that the field be given
instead of 3 feet apart.
In Hawaii, according to Agricultural
Press Bulletin No. 2, quite a different
system is followed on some farms situ-
ated near the sea level. After prepar-
ing the land, the seeds are planted at
distances of 15 feet in rows 20 feet apart,
which gives 150 plants to the acre. As
soon as the plants are 2 feet high the
terminal bud is ripped off so as to force
the production of lateral shoots, which
are in turn shortened to compel the
plant to branch as much as possible and
keep down the height, so that the spikes
may be harvested tiom the ground and
in order to increase the number of bear-
ing shoots.
The plants begin to flower when from
eight to nine months old, and the seed
matures in about ten months. During
the growing period the plants should be
well cultivated. Under this system the
crop is kept growing and should pay
commercially for from five to seven
years, but during that time must receive
occasional dressings of manure,
{Marcu, 1909. oF =
$75 to $80.
Marcu, 1909.] 231
The spikes or seed clusters should be
gathered as soon as ripe, which is indi-
cated by their beginning todry up, split
open, and throw out the seed.
After picking, the spikes may be
spread on a_ piece of hard, smooth
ground and turned occasionally so that
they will dry rapidly. Where there is
danger of rain while the seeds are dry-
ing, it is necessary to have a proper
house with shelves made of slats on
which the spikes can be placed and
stirred cccasionally, the openings
between the slats allowing the beans to
drop through into a trough below where
they can be easily collected.
Profits from the crop are not gener-
ally large, as 12 bushels to the acre is
considered an average yield in the
United States, and they sell there for
from $0°75 to $1 per bushel. In Hono-
lulu, however, the crop is stated to be
from 2,500 to 3,000 pounds per year,
while the maximum yield for Madras
varieties is given at from 400 to 450
pounds per acre. The Honolulu report
goes on to state, however, that the
gross returns per acre seldom exceed
From this it would seem
that as the plants must be grown on
good land in order to produce a success-
ful crop, it is hardly to be reeommended
toan already flourishing community ;
though a rank, strong-growing plant, it
does not necessarily deplete the soil
badly, as all the plant food taken up by
the leaves and stalks remains in the
field, only the spikes and seeds being
removed, and these spikes or their ashes
may be returned to the field after the
beans have been threshed out.
It has been found that 100 pounds of
dry spikes yield about 55 pounds of
beans and 45 pounds of pods. As to
whether or not it will pay the cultivator
to return the pods to the field may be
judged from the amount of fertilizer
contained in them. Hight hundred
pounds of dry pods contain about13
pounds of nitrogen, 46 pounds of potash
and 14 pounds of phosphoric acid, thus
more than equaling in fertilizer value
the same weight of ordinary wood ashes
worth $10 per ton. One thousand
pounds of beans, on the other hand,
remove 80 pounds of nitrogen, 4 pounds
ef potach, and 14 pounds of phosphoric
acid.
ENEMIES OF THE CASTOR PLANT.
The circular of the Royal Botanic
Gardens of Ceylon gives two insects as
being injurious to the plants, one a
caterpillar, Huproctia guttata, Wlk.,
which, though omniverous, shows a

THE COPRA INDUSTRY.
By T. Winson Main.
It has been brought to my notice on one
or two occasions recently that the Sin-
gapore market price of Copra is nearly
always less than that quoted for Ceylon
and the Pacific Islands. In order to
ascertain the reeson for this I recently
made caretul enquiry into the state of
the market and the quality of the Copra
offered for sale. What surprised me
most was the very poor quality of the
Copra imported trom the surrounding
Islands and the Malay States compared
with that from Java and other Dutch
Islands. After examining numerous
samples taken from consignments from
many different parts I am not surprised
that Singapore prices do not compare
favourably with those of other markets.
_ There are several causes which account
for the inferior quality and price of
local copra. The principal cause ap-
pears to me to be the absence of some
system of supervision over the native
and Chinese growers. I believe that in
Java and other Dutch Islands the Dutch
Government examines all Copra_ for
export and only that which is up to
standard quality is allowed to be ship-
ped. Thisina great measure accounts
for the excellence of Dutch Copra, The
second cause is that it is common prac-
tice to pick the coconuts before they
are quite ripe, thus accounting for the
large quantities of thin, soft and decay-
ing Copra on the market. Quantities of
good ripe Copra are frequently ruined
by mixing it with this half-matured
stuff. _The third reason is that the
Copra is badly dried. That said to be
sun-dried is only partially dried, and_as
soon as put in bulk becomes mouldy
and rots. That said to be kiln-dried is
practically roasted. A -fourth, and by
nO means least important, reason is the
absence of any form of beneficial culti-
vation on the estates. In the majority
of instances trees are never by any
chance manured nor is any form of bene-
ficial cultivation practised. The result
of this neglect is an inferior Copra
poor in oil-producing qualities. I am
now referring to Malay and Chinese-
owned estates which comprise prac-
ticaly the whole industry. It is well
known that European-owned estates
produce Copra of the very highest
quality, but unfortunately “for their
Owners, the poor quality determines the
market price,
Oils and Fats.
Ceylon Copra obtains a better price
chiefly because the large majority of
coconut estates there are owned by
Europeans and under European man-
agement, and every care is taken to turn
out Copra of first quality,
The Pacific Islands Copra maintains
its advantage in price principally because
Messrs. Lever Bros. and other well-
known soap manufacturers have exten-
sive interests there. They have repre-
sentatives on the spot who insist on first-
class Copra being supplied, and in return
pay the highest price.
The difference in price between good
and bad Copra in Singapore is about
$1 per picul. The present price for first
quality isabout $7°50. As the price rises
it is customary for many native and
Chinese growers to resort to the inju-
rious practice of rushing quantities of
unripe badly dried Copra on the market
in order to catch the higher rate. This
is a practice which cannot be _ too
strongly condemned.
The principal sources of supply are
Dutch Borneo, the Natunas and Anam-
bas Islands, Johore, the Malay Penin-
sula, and the Dutch Islands generally.
Singapore produces over 3,00C piculs
of Copra per month chiefly from Tan-
jong Katong and Passir Panjang. This,
with the exception of a small quantity
from Kuropean estates, is badly dried
and contains a large percentage of un-
ripe nut.
Dutch Copra_ from Billeton and
Banka is principally kiln-dried and
arrives clean, well.dried and of good
quality.
That from Padang, Sumatra, is in
small pieces well ripened, dry, dark and
oily in appearance and contains more
oil than any other Copra imported to
Singapore. This is due to careful culti-
vation and none but well-matured nuts
being gathered.
The Celebes give us a good Copra, well
dried from fully matured nuts, yields
an excellent oil and shews careful
preparation.
Asahan exports fine large Copra, ripe
and fairly welldried both by sun andkiln.
Pontianak produces dry Copra cf tair
quality containing a small percentage
of unripe nut.
Saigon (Singkawang) Copra is of good
quality, dry, and shews careful pre-
paration.

(Marcu, 1909.
Ternate Islands Copra is very good,
generally dry. Kelantan Copra is good,
but that from Johore (Batu Pahat) is
very Wet, unripeaudmouldy. Rhio sends
good samples of Copra but occasionally
the quality cannot be depended on.
Ihave recently seen shipments from
Malacca and Muar which were very bad
indeed, in fact it is said that Copra from
these two places is the worst sent in to
Singapore. In one store I saw several
lots heating so badly that it was im-
possible to bear the hand between
the sacks. Quite half was unripe and
little or no attempt had been made/at
drying. Iam informed on good authority
that the quantity of bad Copra from
Malacca is steadily increasing,
Selangor Copra from native and
Chinese sources is of fair quality but
contains a good percentage of unripe
put, also sand aud other impurities.
The exports of Copra are to Russia,
France, Spain and other continental
ports, and recently to the United
Kingdom. The exports of coconut oil
from Singapore in 1907 reached 159,801
piculs, of which 40,163 piculs were im-
purted chiefly from Pontianak.

The Director of Agriculture has stated
in his annual report for 1907 that this
important branch of the Agriculture of
the Federated Malay States has increas-
ed in acreage by seven per cent, during
that year, and that the total area under
coconuts at the end of the same period
was 112,500 acres. These facts and the
above figures demonstrate the import-
ance of the Copra industry to the
Peninsula and surrounding Islands, and
also shew that there is a renewed in-
terest in not the least important of our
agricultural staple industries.

A NOTE ON THE PRESENT POSI-
TION AND FUTURE PROSPECTS
OF THE CUTCH TRADE
IN BURMA.
By R. S. TROUP, F.C.H.,
Imperial Forest Economist.
Recent drop in the quantity and value
of cutch exported._Some apprehension
has of late been caused by a marked
decrease in the quantity and value of
cutch* exported from Burma during
recent years, for which various reasons
have been assigned, and asa result of a
detailed enquiry which I have recently
had occasion to make in the matter, it
may be of interest to consider the facts
elicited, particularly as to bearing on
the probable future of the cutch trade.
A glance at the figures in Appendix A.
will show that the net export value of
Burma cutch is now considerably less
than it was ten to fifteen years ago ; it
reached avery low figure in 1904-05, but
has recovered slightly since then. The
coasting trade, on the other hand, does
not show the same marked tendency to
decline in net value, though the quan-
tity now handled ismuch less than it
was formerly.
Drop in local prices.—The local up-
country prices of cutch have also shown
a serious decline. Thus at Pakokku, one
of the local centres of the ecutch trade
in Upper-Burma, cutch sold a few years
ago at Rs. 50 per 100 viss, + whereas of late
the price has dropped to Rs. 25 to Rs. 30.
Temporary fluctuations in the value
of cutch have been of frequent occur-
rence in the past, and are bound to
continue so long as the supplies fluctu-
ate so much as they have done and
still continue todo. Thisis inevitable,
because there is but a limited consump-
tion of cutch, and any production ex-
ceeding this amount is followed, as a
matter of course, by a decline in price.
The permanent decli.e observed for
years past is a more serious matter.
* Cutch is a brownish coloured extract obtained
by boiling chips of the heartwood of Acacia
Catechu, Willd. (including two varieties, A. cate-
chuoides, Benth., and A. Sundra, C.D,). The
liquorobtained by the boiling is further boiled down
to the consistency of syrup, poured into moulds,
and allowed to harden. The valuable constituents
of cutch are a tannin and a crystalline substance
known as catechin, andthe value of cutch as a
tanning and dyeing agent depends on the amount
of these two substances.

Money sunk in cutch plantations and
reserves.—Any tendency towards a per-
manent decline in the cutch trade is a
matter which closely concerns Govern-
ment interests. Up to 1907 cutch plan-
tations aggregating 8,656 acres have been
created and maintained at a total cost,
to date, of Rs. 1,46,044, in addition to
which 6,696 acres of mixed teak and
cuteh plantations have been formed and
maintained at a total cost, to date, of
Rs: 1,00,487: charging half of the latter
sum to cutch, it will be seen that about
two lakhsof rupees have already been
spent on cutch plantations.
Besides this, considerable sums have
been spent in forming and maintaining
natural reserves of cutch forests, sothat
any permanent decline in or total cessa-
tion of cutch trade will bea matter of
grave corcern,
Factors which may account for the de-
cline in the cutch trade.—Several reasons
have been suggested to account for the
decline in the cutch trade. Some of
these are of little value, but there are
three factors which are worth examining
in some detail, and as will be seen
below, the tiue reasons for the decline
in the trade are to be foundin acom-
bination of three factors, which are (1)
the limited uses and demand for eutch,
(2) substitutes for cuteh, (3) adulter-
ation and faulty manufacture.
(1) Limited uses and demand for
cutch.—Owing to the introduction of
cheaper substitutes, the quantity of
Burma cutch now consumed is consider-
ably less thanit it was some years ago,
The world’s annual consumption of
Burma cutch probably does not now
exceed 4,500 tons per annum, and when
this demand is satisfied there is no other
outlet for cutch. Moreover, the price
must bea low one to tempt importers
to purchase in anticipation of future
requirements, as the -cost_ of keeping
cutech in store in Great Britian, and
the loss in weight during about. six
months, adds some 10 per cent. to im-
porting prices. As thespeculative value
of cutch is thus a low one, and as the
quantity of cutch manufactured fluctu-
ates a good deal year by year, the mar-
ket prices of the product must, in view
of the restricted demand, also fluctuate
proportionally, and this fact explains
to a great extent the ups and downs
of the cutch market at comparatively
short intervals, though it does not
entirely explain the drop which has
taken place for a long series of years;
Dyes and Tans. 224
the latter drop is due rather to the in-
troduction of cheaper substitutes. and
to the extensive adulteration which
took place some yearsago. Cutch is
now used chiefly for curing or pre-
serving fishing nets, ard sails, the ob-
ject of cutching nets being to prevent
them from heating, and if they do
heat, to prevent the heat from rotting
the fabric. Dyers have almost entirely
discarded cutch for aniline substitutes.
(2) Substitutes for cutch.—The chief
products which have severely competed
with Burma cutch are mangrove cutch
from Borneo and elsewhere, and aniline
dyes.
Mangrove cutch.—It is believed to be
ejyme twenty years since mangrove cutch
was first introduced to the fishing in-
dustry in Great Britain, but it was not
till 1898, as the result of very extensive
advertising, that it was used to any
greatextent. It hasalso gained a fvot-
ing in Holland during the past few years,
but is not very largely used. Few
fishermen use mangrove cutch alone;
some will not use it atall, while others
use a proportion mixed with Burma
eutch, Mangrove cutch is obtained at a
considerably lower price than Burma
ecutch, and is Jess liable to fluctuations
in price. Although as a preserving
material for fishing nets it is inferior to
Burma cutch, still it finds favour to
some extent because it dissolves readily
and gives a red solution without any
residue. As mangrove cutch does part
of the work for which Burma cutch is
used, it affects principally the cheaper
qualities of the latter, and lessens the
consumption of the cheaper grades of
Burma cuteh. For this reason it is
most advisable to keep the standard of
Burma cutch at the highest possible
level. Mangrove cutch is manufactured
from the bark of mangroves, the chief of
which are Ceriops Candolleana and
Rhizophora spp. The trade in this cutch
in the Straits is an extensive one, the
amount passing through Singapore
alone being over 20,000 cwt. annually.
The imports into Singapore are from
Borneo, Labuan, Sarawak and other
localities, not from the Federated Malay
States, whilst the imports into Penang
are mostly from Sumatra. A large
proportion of the mangrove cutch
imported into Singapore is used locally
and not exported.
The Divisional Forest Officer, Rangoon
Division, reports a local manufacture of
mangrove extract which is not exported
but is used locally for curing fishing
nets and sails; a similar extract is pre-
pared in Arakan.

“LALANG,” IMPERATA ARUNDI-
NACEA, Cyrill) AS A PAPER-MAKING
MATERIAL.
By G. STEWART REMINGTON,
One of our correspondents sent asam-
ple of lalang grass recently to HKngland,
and has received the following report,
also samples of paper made from lalang
grass entirely and half lalang and half
cotton :—
Certificate of Analysis.
This is to certify that the above sam-
ple has been carefully examined with
the following results :—
This grass was forwarded to ‘The
Aynsome Technical Laboratories” for
investigation, that its commercial use
as a source of pulp for paper-making
might be ascertained.
The object of the present report is to
draw attention to the importance and
value of this grass as a pulp-pioducing
material, and to indicate its chief char-
acteristics and economic value.
Ihe sample was a pale buff colour,
lustrous in appearance and of fair
strength, of the order of Gramineze.
“The chemical examination furnished
the following results, the percentages
other than that of moisture being ex-
pressed on the dry material :—

Cellulose a . AT 41
Length of Ultimate Fibre 1:20 m.m,
The ultimate fibre obtained from this
grass is very similar in most respects to
Ksparto; the yield of bleached fibre being
about the same. This is a favourable
indication inasmuch as ‘‘ Hsparto” is
one of the best known and most useful
sources of supply to the trade. The
fibres as seen under the microscope
are short, smooth, cylindrical, fairly
uniform in diameter, gradually taper-
ing to rounded extremities; they also
occur together in little bundles. The
pulp will be found to contain a number
of small cuticular cells which do not
however shew in the finished paper.
The fibres are stained a pale yellow with
iodine solution, which fades more
radidly than is usual with coloured
pulps,
The results obtained from the chemi-
cal analysis show the grass is capable
of yielding a good quality of cellulose,
suitable in every way for the manu-
facture of paper. Although the grass
is very susceptible to the action of
dilute alkalis, the final product is ex-
ceptionally pure and readily resolved.
From observations noted during this
preliminary examination the following
scheme was adopted for the production
of the pulp on a large scale.
PROCESS.
The available grass in its natural con-_
dition weighing 400 grams (14:1 0z.) was
inaclean state, and required little treat-
ment beyond cutting into small pieces’
ready for boiling. It is usually neces-
sary on a large scale to pass the material
through some type of cleaner to _ re-
move dirt andadventitious matter. The
grass was then thoroughly wetted and
soaked until it became soft and pliable.
It was placed ina boiler of the spherical
type, covered with water and digested
with caustic soda corresponding to 15 7
on the grass treated for a period of ten
hours under a pressure which was kept
constant at four atmospheres; an even
temperature about 135° C, being main-
tained.
Owing to the quantity of material at
our disposal being somewhat limited,
it was only possible to conduct one
experiment, consequently a good margin
in the use of caustic and a degree of
general treatment was allowed.
The pulp obtained after washing was
of good uniform quality and colour.
The yield agreed very closely and was
only slightly higher than the prelimi-
nary chemical analysis shewn, which in-
dicates complete reaction in the digester.
The pulp was carefully beaten for
about an hour and at the same time
bleached, chloride of lime being used for
the purpose; 10 parts of dry powder
being used for 100 parts of pulp.
The stuff was taken from the beater
and _ well washed, and subsequently a
small quantity of loading was gradually
added and the whole agair beaten for
half-an-hour. At this stage of the oper-
ation the rosin size was introduced and
the decomposition of the soda resinate
completed with the calculated quantity
ofalum. The amount of size used cor-
responded to4% on thedry pulp present,
the total time occupied in preparation
of the pulp for running on the machine
being two hours,
Fibres.
PREPARATION OF PAPER.
No great difficulty was experienced in
running the pulp; it retained, however,
a considerable quantity of water after
passing the suction-boxes, and in conse-
quence it was found necessary to keep
the press roll down hard. On a large
machine this precaution would not be
necessary, aS more suction-boxes are
available and complete control is
assured.
The paper was passed over nine eylin-
ders at a pressure of about 8 lbs. to the
square inch, then through one calendar
and finally reeled off. In asimilar man-
ner a second sample was prepared, using
a mixture of half pulp obtained from
the lalang grass and half cotton beaten
together. The paper obtained from this
blend could prove very useful as a high-
class wrapping paper, it being stronger
and possessing a comparatively high
resistance to folding as will be seen in
the following table of physical tests
done on the finished specimens of papers.
The paper made from ‘‘all-grass” pulp
would with judicious treatment for
improvement of colour be very suitable
for printing purposes.
The following table of figures was
obtained and compiled from tests and
analyses made on the air-dried finished
papers :—

PAPER FROM RICE STRAW.
Some time back inquiries were made
by persons interested in the rice growing
industry of this colony as to whether
the rice straw could not be utilized for
the manufacture of paperin the same
way asthe straw of other cereals, viz.,
230
[MARCH, 1909,
rye, wheat, oats and barley is employed
in countries where these are grown.
The following note from the ‘‘ Louisiana
Planter and Sugar Manufacturer,” Vol.
XL., No. 25, provides an answer to this
question, and shows that by the estab-
lishment of a pulp mill, paper pulp might
be produced locally for shipment to
paper mills to be there manufactured
into paper.
‘Rice farmers have long been in
search for some better use for the straw
than feeding it to stock for which it is
worth very little in the way of nourish-
ment. Recent advices from Beaumont,
Texas, state that Mr. W. D. Wing, a pro-
minent capitalist of Bangor, Maine, be-
came interested in the proposition of
making paper pulp from rice straw, and
to ascertain the elemental qualities of
the straw in this respect he sent some of
the straw to a chemist for pulp mill in
Boston, and had some sample paper
made from the straw. During his recent
visit Mr. Wing exhibited these samples.
Notwithstanding they were made
entirely by hand in a laboratory, the
samples proved to be excellent quality
of paper, capable of retaining ink and
suitable for many purposes for which
paper is used.
Mr. Wing owns a large amount of
stock ina pulp mill in Maine, and is
therefore interested in this matter from
another standpoint than to merely make
use of the rice straw. His experiments
thus far have proved conclusively that
rice straw will make an excellent pulp
for making paper, and it is his idea that
a pulp mill should be built in this terri-
tory, and perhaps several mills in
different sections of the rice belt for the
purpose of utilising this straw. He does
not go into the question of building
paper mills here, for the reason that
paper mills are very expensive, and
there may be many questions involved
in the operation of a paper mill which
are not involvedin a pulp mill. At any
rate, Mr. Wing for the present is inter-
ested in thepulp proposition, and his plan
roughly outlined is to establish these
mills, making the pulp from the rice
straw, and ship to the paper mills in the
New England States.
From estimates so far made Mr. Wing
believes that the farmer can net $2 per
ton for the straw on the farm. This
does not include hauling, palin and
shipping, but means that the rice farmer
will receive $2 for each ton of rice straw
produced.
Mr, Wing has arranged to ship a large
quantity of straw to his mill and
demonstrate satisfactorily what sort of
paper can be made frcmthe straw. Mr.
Wing is not speculating lightly in this
8 Vee
\
Marcu, 1909. ]
matter, but is thoroughly interested,
and if his expectation as to the merit in
the straw prove out, he will lose no time
in building his pulp mill somewhere in
the belt and will ship the pulp to the
mill in the north. In addition to the
value of the straw for paper making,
Mr. Wing finds that there is a large
quantity of rice leftin the straw, and
from this he believes very many articles
of trade, such as alcohol and feed-stuffs
can be n.ade. In fact, Mr. Wing believes
that rice straw can be utilized almost as
much as cottun seed, which not so many
vears ago were thrown away, as many
farmers now living can remember, As
there are about 60,000 acres of rice
planted in Jefferson County each season,
it will be seen that there is produced
about 120,000 tons of rice straw, which, at
$2 per ton, will yield $240,040, which
has heretofore and would otherwise
be thrown away.’”-—-“ Abbeville Meri-
dional.”—Journal of the Board of Agri-
culture, British Guinea, Vol. LI., No. 2,

CARAVONICA COTTON.
In Monte Cristo, in the most easterly
part of Cuba, 1,500 feet above sea-level,
was last autumn planted about fifteen
acres with Caravonica silk, and about
fifty acres with Caravonica wool-cotton.
Although the pianting could not be done
till the first days of December, as the
seeds ordered from Australasia did not
come before that time, the result is most
satisfactory for both varieties, The
trees have borne and are stiJl bearing
very richly. Samples of the cotton
have been sent to several experts in
America and KEKurope, and from. all
quarters the cotton has been praised for
strength, gloss, and length of staple.
By this enterprise it seems to be proved
that of all kinds of cotton, known
up to date, the Caravonica is the best
one for planting in Cuba, as it pos-
sesses a considerable power to resist
drought, storm and insect pests,
We have planted our trees at the dis-
tance of 7 by 7 feet, but according to our
experience we will recommend planting
8 by 8 feet, as even at this time--in the
middle of September—most trees have
grown toa height of 11 by 12 feet, some
of them are still higher. We shall have to
prune them rather severely for giving
them more sunlight and facilitate the
picking.
After all, the enterprise seems to bea
very profitable business. new area is
cleared, and when planting the new
acreage—which planting is to take place
in September--we shall have the great

This is a very interesting result. Cuba
is cooler than Jamaica, and at 1,500

THE FIBRE INDUSTRY.
By LEONARD AcutTt, J.P., Tongaat.
This industry is not attracting the
attention in Natal which it deserves,
and I do not think the area of land
devoted to aloe-planting is on the in-
crease. It is true that extension to some
extent is being carried on on the South
Coast, but, on the other hand, some
large plantations both on the South
Coast and in Zululand have been
abandoned.
Since my first visit to Mauritius, [
have naturally taken an interest in fibre,
and it is with much disappointment that
I have seen so little doing. I pen these
notes in the hope that they will result
in more being done to increase our
acreage of aloe in the near future.
ITam_not wishing to alter anything
which I said last year in my ‘“‘ Report on
the Fibre Industry of Mauritius,”* but I
merely wish to emphasize a few points.
which, though I mentioned them in that
report, appear to me to be worthy of
special attention.
In that report (page 1208) I said
“The main danger we have here
threatening any aloe plantations is that
of fire. The cultivation of Creole aloe
need only be of the roughest possible
description, but a rough cultivation in
this country means a quantity of grass
and debris which becomes dangerously
inflammable in the winter. In Mauritius
this does not occur, the grass and debris
is not, beyond the small patches, in-
flammable at any time of the year.
Therefore (in Natal) either cultivation
would have to be done to keep down the
grass, or we should have to be careful to
prevent outside fires coming in, and
keep all roads and paths in the plant-
ations themselves free of inflammable
material.”
Now, the first of the above two alter-
natives is, at the best, costly, and the
other is dangerous and means a great
risk, which is not good enough business to
attract capital, and it is more than
probable that losses by fire have con-
tributed largely to the failures of some

Fibres.
fibre companies or syndicates in our
Colony, and the greatest care will have
to be exercised in the selection of land
and locality for fibre culture, and the
most favourable circumstances secured
for cultivation and protection from fire.
I would not be taken in any way as
wishing to discourage the making of
plantations. Let us by all means proceed
along the lines of regular and systematic
planting and cultivation of aloes for
fibre-making, and let us be most careful
in selection of land, There is a great
future before the enterprise, but in
watching the progress and prospects of
the industry in Natal I am inclined to
attach more importance than I did last
year toa point which I touched on in
my report in the following words :—
‘1 do not doubt that there are many
districts in the upper part of the country
in which aloes would do well, Many
parts of the ‘Thorns’ certainly would
suit, and there are thousands of acres
which are fit for no other crop, by reason
of stones and poor rainfall.”
Now, these thorn lands more nearly
approach the conditions under which
we find aloes growing in Mauritius in
that the ground is rich and the climate
dry. Moreover, in some districts in
Natal I have in my mind’s eye, the
stones are so thick that there is never
sufficient growth of grass to make such
a fire as would injure the aloe plants,
but the hills are covered with a growth
ot native aloes, brambles, etc., against
which the Furcrea would hold its own,
and if afew thousand “ bulbils” of this
aloe were planted by everybody owning
a thorn farm, or even if the bulbils were
dropped about, the country would ina
few years be as much covered with fibre
aloe as the Island of Mauritius is to-day,
and a revenue would be obtained at any
time when other work was slack. The
cost of cutting the leaves and bringing
them out of stoney places would be
great, but against that would have to be
set the fact that they had cost nothing
to grow and the collection of the leaves
would probably be a class of work which
would suit the kraal Kafirs, men, boys,
women and girls. Planting, or broad-
casting, the ‘“‘bulbils” would be necessary
atfirst, but once the plants were old
enough to throw up the “poles” with
their crop of bulbils the aloe would
spread with great rapidity, as the bulbils
would be carried by the winds, and
would hold their own against any
native plants.
I have mentioned the idea to several
«thorn ” farmers, and I hear that Messrs.
Evans, Worthington & Walters at their
farm ‘‘N’Kashin” are taking the matte1
upand getting up bulbils from the coast,
202
a ae |
-{Marca, 1909,
and I feel sure that they will have cause
to be thankful that they started the
work. What a field there is in the
growth of wild aloes in this manner!
and without taking up land on which
something else can be grown.
When one contemplates the poten-
tialities of fibre culture in this way, one
wonders that the idea does not seize upon
the mind of the people, but to dip in
Jordan is, of course, too absurdly simple.
Hundreds of thousands of acres of
practically desert country in the valleys
of the Tugela, Umvoti, Bushman’s, and
Blue Krantz Rivers might be utilised,
and Zululand’ could spare as many acres
more and not miss them.
I find in my report the following
paragraph :—
“T think this would be a crop which
the native might be encouraged to grow.
Young plants might be scattered broad-~
cast in kloofs and sheltered spots in
locations; and the aloe might take
charge of such places as it has done to
such an extent in Mauritius, and prove
a source of income in afew years’ time,
and make productive alarge area of land
on which nothing else can be produced.”
I cannot imagine anything better that
could be done for our natives than
covering large tracts of location lands ~
with aloe; in course of time a large
tonnage of leaves would be available,
and men would not be wanting to put
up machinery and pay a fixed price per
100 lbs. for the leaves, and thus give
employment to the swarming population.
The * bulbils” are generally procurable
for afew shillings per thousand on rail
at coast stations.
I trust that these few notes will induce
everybody with suitable land to plant if
only a sackful of plants, which can be
done at any time of the year when
plants are procurable. Another way in
which to cover one’s land quickly would
be to get some well grown aloe plants
from the coast ; these would flower in a
year or two and give enough plants to
cover a large area of ground.
If Mauritius, a small island, only 34
miles by 22 miles, containing only 456,320
acres, can on its waste land produce
£100,000 worth of fibre, asit has done,
although the value of the output for the
last four years was only £45,000 a year,
what could Natal produce on its 16,000,000
acres, exclusive of Zululand ?
A great industry is ready to our hand
and one not requiring a large outlay.

is so obviously within ou reach.—Natal

SUGAR CANE CULTIVATION.
PRACTICAL INFORMATION FOR
BEGINNERS.
We have received a considerable num-
ber of requests during the last few
months, more particularly from persons
who have taken up some of the new
sugar lands on the Zululand coast, for
information with regard to sugar-cane
growing, and, in accordance with these
requests, we have pleasure in publishing
some ofthe most useful of the infor-
mation which we have immediately
avaliable. Inthe February and March,
1905, issues of the Journal there were two
instalments of an interesting article by
Messrs. A. N. Pearson and Alex. Pardy,
on ‘‘The Sugar Industry of Natal,” and
in the course of that article some
practical information was given with
regard to the preparation of the soil,
manuring, planting, weeding and trash-
ing, harvesting, ete. Those issues of the
Journal are, however, now out of print,
and we accordingly republish such of
the information given as will be of most
practical value to beginners and others.
In early issues of the Journal further
articles on sugar-cane cultivation will
appear.
VARIETIES OF CANE.
Besides the Green Natal, supposed to
be indigenous, many imported varieties
of cane have been introduced. At one
time a variety known as China cane was
extensively grown, but it suddenly
succumbed to a species of smut, Ustilago
sacchari, and had to be discarded. The
other varieties tried are principally
Lousier, Fotiogo, Bois-rouge, Imperial,
Tamarand and Belle-ougete, said to be
from Mauritius; Ribbon, Bourbon Yellow
and Bourbon Purple, probably from
Bourbon ; also White Queen (one of. the
best in good seasons), Port Mackay, Gold
Dust (white and red), and Rose Bamboo,
None cf these are now generally
cultivated; they have almost every-
where been supplanted by a variety the
correct name of whichis unknown, but
which is here called Uba, a name, it is
said, formed of the only letters remain-
ing legible on a damaged label attached
to the variety on its first arrival in the
country.’ Mr. Medley Wood thinks it
was introduced by Governor Sir Charles
Mitchell, who, on returning from a visit
to India in 1884-5, brought two Wardian
cases containing cane plants, only three
of which were alive. These were pro-
pagated by Mr, Wood, the resulting
30
plants being given to Mr. Anthony
Wilkinson. It is generally admitted,
however, that this cane was introduced
in quantity by Mr. De Pass of the
Reunion Estate. From a milling point
of view, this cane is undesirable; it is
thin, tough, wiry and fibrous, and the
juice, it is said, needs special care in the
treatment ; mill managers say that from
10 to 80 per cent. more mill power is
required for this cane than for any other
variety. But the planters like it, since
it endures the uncertainty of the Natal
climate better than any other variety yet
tried; it is hardy, bears frost and
drought, stools prolifically, recovers
readily from locust attacks, is subject to
no fungus pests, and but little damaged
by white ants and the borer. It is
successfully grown on the highlands of
the interior as forage for cattle.
Within the last few’ years several
varieties have. been introduced from the
West Indies, British Guinea, Mauritius,
Queensland and Honolulu, the Depart-
ment of Agriculture having co-operated
with the planters for their importation.
The Inanda Association have taken a
leading part in this movement, and
several of the canes have been propagated
for distribution on their behalf by Mr,
H. W. James,.of Verulam. Some of those
from the West Indies were sampled by
the Department of Agriculture and
analysed.
Hitherto it has not been the custom to
analyse Natal canes, the chemist, in fact,
being. but little recognised by the in-
dustry, and therefore no exact com-
parisons of the juice of the different
varieties as grown in Natal can be made.
The following few statements of analysis
are, however, available :—

no inferiority in the juice; in fact, the

by analysis, would not be readily sur-
passed anywhere.

analyses generally show that, so far as
quality is concerned, the soils and
climate of Nataladmit of cane being
grown here as well as elsewhere.
SOILS.
The soils of the planting districts vary
considerably, there being light grey
sands, red sands, light loams, chocolate
loams, sandy clays of all degrees of tex-
ture, grey alluvials and black alluvials.
Many of these soils may be on the one
farm, and even in one cane field. The
prevailing soil is a red or chocolate
ferruginous sandy loam, light in texture
and easy to work whenonce broken up.
This class of soil is often very fertile
when first cleared of bush, and has been
known to give yields in good seasons of
four and five tons of sugar crystals per
acre from the plant canes. At one time
the cane was grown exclusively in_ the
alluvial flats, some of which have been
in continuous cultivation for 40 years,
and still yield well. But many are of
poorer quality, and as crops grown in
them are subject to flood and frost, it
has been found advantageous to plant
on the hills, even on the steeper slopes
where only hand labour can be applied.
According to Mr. Wm. Campbell,
‘“tambootie grass” land is excellent for
cane.
PREPARATION OF THE GROUND.
In newly-cleared bush land the canes
may be planted without ploughing. The
bush having been cut, the timber stacked
and the scrub burnt, holes may be
grubbed out with hoe and axe, and the
cane planted straight away. Grass land,
however, requires to be broken up,
allowed to lie for a time, and then cross
ploughed and harrowed. For planting
old cane lands the ratoons are ploughed
out—with the mould board plough, and
recently with the disc plough—and the
land is then cross ploughed and harrowed.
MANURES.
Very little manure is used other than
mill refuse, but in the reighbourhood of
Durban stuff is carted out from the
Corporation stables, and in afew cases
small quantities of artificials and bone
dust are applied. Kxperiments now
being conducted by the Department of
Agriculture, both on the Coast Experi-
ment Farm and on private farms, suggest
that many of these lands may be mate-
rially benefited by the judicious applica-
tion of phosphatic manures.
PLANTING.
_ The cane is planted in rows five or six
feet apart, or even nearer in poor land,
and further apart in very rich land.
The land is either drilled out with the
drill plough working 9 or 10 in. deep, or
it is holed out in lines by hand hoes, holes
being made 1 ft. wide, 8 or 10 in. deep,
and 15 to 2 ft. long, a space of from 6 to
18 in. being left between each. Some-
times whole canes are used for planting,
these being laid two together in the
drills; or the canes are cut into lengths of
five eyes to each: many, however, prefer
only the tops which have been cut off
when the canes are harvested for the
mill. These are laid, two, three or four
together, in the holes or drills, at dis-
tances of 1 to2 ft. apart. The cuttings
or sets having been planted are loosely
covered with about an inch of soil. As
the young shoots grow up, the covering
of soil is increased until the drills or
holes are filled. The shoots appear in ~
from 10 to 20 days. according to the
-weather and the vitality of the sets.
The general time for planting is August
to September, but it may be done as late
as December and January— Natal Agri-
cultural Journal, Vol. XI., No. 12,

THE ‘“PULQUE MAGUEY”
OF MEXICO.
Under the title ‘The Century Plant
and some other Plants of the Dry
Country,” Professor William Trelease,
ot the Missouri Botanic Gardens, con-
tributed a highly interesting paper to
the ‘“‘Popular Science Monthly” of March,
1907, dealing with the various agaves
found in Mexico and their characteristics
and uses. This paper includes a lengthy
account of Agave atrovirens, or the
“‘pulque maguey,” from which the na-
tional alcoholic drink of Mexico is pro-
duced. The details given below as to
the methods followed in the manufac-
ture of pulque, and the extent of the
trade in this product, are extracted from
Dr, Trelease’s article :—
South of the city of Mexico, centreing
about the little town of Apam, the
species of agave is almost exclusively the

dark-green giant A. atrovirens, though,
as with extensively cultivated plants
elsewhere, itis grown in numerous hor-
ticultural varieties which look much alike
to the botanist but are distinguished by
the planter. Over thirty such forms are
Said to be planted in the plaius of Apam.
As one passes to the colder regions of
the north or descends from the table-
land into the hot country, still other and
different looking species of the same type
replace A. atrovirens, which, however,
far outnumbers and surpasses them all
initsaggregateimportance. These plant-
ations of A. atrovirens are the basis of
the pulque industry of Mexico—at once
a large item in its agricultural wealth
and one of the greatest curses of its
labouring population.
The present traffic in pulque is large.
, Something over 5,000,000 barrels of it are
used in the Mexican republic every year,
of which quantity about half is consumed
in the capital city, and much of the re-
mainder in Puebla and the other large
' cities of the central plateau. Cheap as
it is (for it sells for from 1 to 3 cents of
Mexican money for a large glass), its
aggregate value amounts. to several
million dollars per year. Special trains
are run into the city of Mexico every
morning for its delivery, as is done with
_ the milk supply of American cities, In
the Apam district the plantations are
chiefly found on the large haciendas or
estates.
The “ pulque maguey” is a large plant,
and its rosette of thick leaves, though
appearing to lie next the ground, is really
spaced along a stout trunk as large as a
small barrel. The whole, charged with
sap, weighs several tons. If left to itself,
as it is in gardens on the Riviera, where
it is called A. salmuiana, like the century
plant Agave americana, it produces a
gigantic scape, topped with a candela-
brum of flowers, when somewhere in the
neighbourhood of fifteen years old. This
is never permitted on the large plant-
ations, for the plant possesses its maxi-
mum value when it has reached vege-
tative maturity and the scape is about to
develop. At the critical moment, known
from the appearance of the central bud,
this is cut out, andashallow cavity is
made in the crown of the trunk, which
is covered by a stone, pieces of maguey
leaves, or other protection. Into the
cavity so formed the sap exudes.
It is removed two or three times a day,
the surface being scraped and the cavity
slightly enlarged each time, until at
last nothing but a thin shell of the trunk
remains, the leaves meantime having
given up their content of fluid and dried
to their hard framework—as happens
naturally during the flowering period of
235 Hdible Products.
all the larger agaves, when the reserve
of sap is drawn into the rapidly growing
scape and flowers,
For a period of three months or more a
good plant yields a gallon or two of sap
daily, and its total value may be not far
from 10 dollars on an average, from
which it will be seen that a large maguey
plantation represents a considerable item
in the assests of a landed proprietor of
the plains of Apam.
The fluid which collects in the hollow-
edtrunk of a cut maguey plant, and is
gathered in the manner described, is
called ‘“‘agua miel,” or honey-water, be-
cause of its sweetness; 9 or 10 per cent.
of its weight is sugar, and this furnishes
the basis for the alcoholic fermentation
which is the chief factor in its con-
version into pulque. The ‘‘agua miel”
of the Apam district is thin, clear,
and colourless, and possesses a rather
pleasant taste.
The fermentation practices in pulque
making are still mostly primitive. I
have hada Mexican gentleman tell me
that, although when the agua miel was
gathered and fermented with due clean-
liness he considered it a delicious drink,
he would not think of touching pulque
as offered, for instance, at the railway
station at Apam. The vats used in the
fermentation are of ox-hide stretched on
frames, and they are usually 3 or 4 ft,
wide and nearly asdeep. Fermentation
is begun by the introduction of a starter
or ‘‘mother of pulque,” obtained by
perliminary fermentation, and is car-
ried on either without, or at most with
little, artificial control of temperature,
aud under conditions of positive or nega-
tive cleanlinesss which differ with the
various haciendas,
When marketed, the pulque is a white,
decidedly viscous fluid containing about
8 per cent, of alcohol ; fermentation has
not been solely alcoholic, however, and
its flavour is in part due to changes
wrought by bacteria of several kinds
which are introduced with the starter in
company with the yeast. Continuation
of the action of these collateral ferments
causes the beverage to spoil ina day or
two under ordinary conditions.
Where the maguey, though capable of
cultivation, yields a lesser or inferior
product, agua mielis often more appreci-
ated in its unfermented state. As hawk-
ed around the streets of Monterey, for
instance, in porous earthenware recep-
tacles, it is a cool, yellowish fluid, that is
very refreshing on a hot day, and the
limpid, yellowish, cidery, foamy product
of its fermentation in the north is fre-
quently more to the taste of the foreigner
Fdible Products. 236
than the white, viscous, odoriferous
pulque of the Apam district—which alone
pleases the adept.
Considerable medicinal virtue has been
claimed for pulque, and some efforts
have been made to specially prepare,
bottle, and pasteurise it for medicinal or
even table use; but, except in the region
of its production, where it is the com-
mon beverage, the bulk of it is used as an
intoxicant, pure and simple. From it is
also produced a rather small quantity of
distilled liquor—‘‘ mezcal de pulque.”
Mezcal is a term applied comprehen-
sively to the liquor obtained by distil-
lation from the fermented juices of
ayaves. Four or five million gallons of
it a year are produced, and its value may
amount to some 2,000,000 dollars. The
centre for the manufactue of this be-
verage is to the west of Gudalajara, and
the town of Tequila, situated there, has
given its name to the higher grade of
liquor, which is clear, smoky, rather
smooth, and with a characteristic essen-
tial flavour; it usually contains 40 or
50 per cent. of alcohol, and, like pulque,
possesses certain medicinal properties.
Mezcal issoldcheaply. Itis to be found
everywhere, and contributes largely to
the demoralisation of the native labour-
ers, who often drink it to excess.
To supply the distilleries at Tequila, a
considerable acreage is planted to mezcal
agaves. Those chiefly used for the pur-
pose belong to a well-marked, narrow-
leaved species, which a few years ago
received the appropriate and distinctive
name A. tequilana.—Queensland A gricul-
tural Journal, Jan. 1909, Vol. XXIL., Pt. 1.
ARROWROOT-GROWING IN
QUEENSLAND.
The cultivation of arrowroot in this
State dates back to 1864, It was then
grown at Oxley Creek by Major A. J.
Boyd, who manufactured the commercial
article by the primitive process of
grating the bulbs and purifying the
starch by straining it several times
through linen stretched over tubs. The
product was then readily sold at Is. per
lb. Later on Mr. Boyd sold the bulbs to
Mr. Grimes, who also grew arrowroot at
Oxley and on the Brisbane River, where
he erected the first arrowroot mill
installed in the State. The bulbs were
sold at £2 10s. per ton; and on the then
virgin scrub soils between Oxley Creek
and Rocklea, or Rocky Water Holesas
the place was then called, the return was
enormous. Mr. Grimes grew both the
Marauta and the Canna edulis, but the
former, owing to the small production
of bulbs, was found not to be profitable.
‘
[Marca, 1909.
At the present day all the arrowroot
manufactured in Queensland is produced
in the Albert, Pimpama, and Nerang
districts. At Pimpama the Messrs.
Lahey had extensive plantations and a
well-equipped manufactory. Ornieau,
where a considerable quantity of arrow-
root is grown, was taken up under the
old ‘Sugar and Coffee Regulations,” by
Major Boyd, who erected asugar mill
and grew cane for several years. He
named his plantation ‘‘ Ormeau,” hence
the name of the railway station on the
South Coast line. A very interesting
account of the arrowroot industry, by
H L.—presumably Mr. Leahy—
appeared in the ‘ Brisbane Courier” of
17th October last, and we reproduce it as
showing the rise and progress of the
industry since its initiation :—
GROWERS AND PRICES.
At present the growers are all situated
about Yatala, Pimpama, Ormeau, and
Nerang, and the principal ones are
Messrs. J. Latimer and Sons, Doherty
Bros., R. Doherty, Mayes, W. Murtha,
Mills, J. Bull, and Mrs. Clarke. The
total area under cultivation is about 200
acres, and Messrs. Doherty Bros. and R.
Doherty are the largest growers, having
between them about 100 acres, while
Messrs. Latimer Bros., at Nerang, have
35 acres. The other growers cultivate
10 to 15 acres each of this product. The
yield ofthe marketable product ranges
from 15 to 30 ewt. per acre, and the total
production is about 690,000 lb., or just
the same as was estimated by Mr.
Samuel Grimes, in an article written by
him on arrowroot cultivation in 1888.
_The price to the grower varies con-
siderably. Two years agoit brought
about £10 a ton, but this year the
demand has increased, and fully £20a
ton has been obtained. The demand has
been largely stimulated by the spread of
the knowledge that arrowroot is quite
equal to starch for most kinds of
laundry work, while even at present
prices itis only half the cost. As_ its
value as starch becomes more widely
known, there is little doubt that a
market will be developed fora largely
increased supply. Taking the figures
for last year, we find that 1,284,815 lb. of
starch, valued at £17,375, was imported
into Queensland, mostly from Victoria,
and much of thiscould no doubt be
replaced by the cheaper and equally
effective arrowroot for all classes of
laundry work, except cold starching—
that is, in the case of such articles as
shirt fronts or collars. Although its
use asa starch is by no means new,
the knowledge of it has in the past been
limited and it is only recently that it
MARCH, 1909.1
has come into popular vogue. for years
past arrowroot has_ been utilised chiefly
for culinary purposes, such as the manu-
facture of superior quality biscuits,
light cakes, and easily digested foods
for invalids.
MARANTA AND CANNA.
The Queensland arrowroot is really
the starch product of a bulb of the
Canna tribe of plants—namely, Canna
edulis. Thisis mentioned particularly
because it differs from Bermuda arrow-
root, and cannot be sold in Great Britain
as arrowroot without some qualifying
term attached, such as ‘‘Queensland
arrowroot” or ‘* Australian arrowroot.”
How this has come about is rather
interesting. When the Drugs and Hood
Act was passed by the Imperial Parlia-
ment, it was specified that arrowroot is
the product of the plant Maranta
arundinacec. That is what Bermuda
and Mauritius arrowroots are made
from; and manufactured arrrowroot
from the Canna edulis was then practi-
eally unknown in Great Britain. How
little actual difference there is between
the two is indicated by the following
analysis, taking the best Bermuda
arrowroot (Maranta arundinacec) at 2s.
6d. per lb., and the Queensland arrowroot
(Canna edulis) at 2d. or 3d. per lb, :—
Bermuda Queensland

Starch es 82°24. 81°52
Ash *124: 142:
Proteids 052 078
Fibre 4:09 to 1:20 “20
The result is, therefore, chemically
about the same, particularly in regard
to starch, which is the chief constituent.
There is a little more moisturein the
Canna, and more fibre in the Maranta.
Under the microscope the Canna arrow-
root shows a more silky texture, and the
grains are slightly coarser.
The Maranta arundinacee
equally well in Queensland with the
Canna edulis, and arrowroot-growers
have at various times cultivated it. It
has been known as white arrowroot
(from the colour of the bulbs), while the
present article is called purple arrow-
root. The reason that Maranta has
never become popular here is that it
yields only half the quantity of arrow-
root given by the Canna, and the
growers could get no more for the
product; and also because the excess of
fibre in the Maranta made the matter of
treatment more difficult.
METHODS OF CULTIVATION.
A visit to some of the arrowroot farms
has just been made to ascertain how the

industry is progressing, and how itis
being conducted. There is a similarity
among them all. The rich alluvial
pockets along the banks of creeks are
the growing grounds. A manufacturing
plant, comprising boiler, engine, pump-
ing, pulping, and straining machinery
is required, which costs about £500.
Then there has to be a drying ground,
with the requisite frames, and a shed
for storage and packing purposes.
The bulbs of the Canna are sown in
prepared ground from September to
December, when the weather is showery,
the rows being 6 ft. apart and 4 ft.
between the plants, The usual cultiva-
tion follows to keep the ground clear of
weeds until the plants get tuo big. A
field of Canna presents a pretty sight,
the broad leaves of dark-green giving a
fine impression of richness, and some-
times also scarlet flowers are to be seen
on the plants. From six to eight
months brings the crop to maturity, and
a little frost is then beneficial by shrivel-
ling up the tops and concentrating the
starch in the bulbs, The tops are eut
off by means of a cane knife or bill hook,
and the bulbs—something like potatoes,
but larger—are then dug as required
for milling.
PROCESS OF MANUFACTURE,
The bulbs are carted to the milland
shovelled into a root-washer—a trough
10 ft. or 12 ft. long, through which water
is continuously flowing, and in which a
splindle revolves and works the bulbs
up to the end of the trough, There an
elevator receives them and carries them
up to themill. There they are grated in
a grinder, or perforated wooden drum,
revolving at great speed, and the pulp
passed through to a sieve of perforated
metal, clean water all the time falling on
the pulp. A beater forces the farina and
water through the sieve, while the fibre is
discharged on toa dump. The farina
from the sieve goes into a revolving
copper drum, which has.also perforated
sides, and this takes away some more
of the impurities, while the farina goes
down into a long trough, through which
a stream of water is constantly running.
The arrowroot settles at the bottom of
the trough, and after some hours of
washing is dug out and put into tubs,
or other troughs, and more clean water
with it. _ That is repeated three times,
the farina during the last having to
pass through asieve of a fine muslin.
After that the arrowroot is dug out,
placed on calico sheets, and put out
on frames to dry. The whole process,
from the digging of the bulbs to the
drying of the prepared arrowroot,
occupies about twenty-four hours.
Edible Products.
It will easily be seen that it is of
little use trying to manufacture arrow-
root unless there is a plentiful supply
of good clean water. Mr. J, Latimer,
who had eight acres under arrowroot
at Yatala this year, was working his
mill two or three days a week, and pro-
ducing about half a ton of arrowroot
aday. Todo this, he estimated that
24,000 gallons of water were used in
eight hours.
The refuse, fibre, and pulp are carted
back to the fields for use as manure.
After drying, the arrowroot is ready
for bagging, and it is put in sacks lined
with calico ready for market. Most of
the arrowroot is brought to Brisbane
by steamers on account of the cheaper
freights. By railway from Stapylton to
South Brisbane (24 miles) the freight is
8s. per ton, and 2s. 6d. more has to be
paid for cartage to business places in
the city—a total of 10s. 6d. per ton if by
rail. By steamer from Yatala_ the
freight is 5s. per ton and Is. 6d. a ton
cartage from the wharf to the stores—
total, 6s. 6d. By train the cost from
Nerang is 12s., andby steamer 8s.;so that
the advantage of water carriage will
easily be recognised in the case of pro-
ducts which leave only a small margin
of profit.
Mr. T. Doherty, one of the principal
growers, remarked that arrowroot gave
about the same return as corn or pota-
toes, but it wasasurer crop. It would
stand flooding that would kill potatoes,
and dry weather would not affect it so
adversely as it would corn.
At the Melbourne Exhibition,
Murtha received the gold medal for
arrowroot, and J. Latimer the silver
medal; and at Karl’s Court Exhibition
(London), in 1889, Messrs. J. Latimer and
Sons received asilvermedal and diploma
for their exhibit of arrowroot.
EARLY HISTORY oF ARROWROOT.
The name of Mr. Samuel Grimes has
long been connected with arrowroot
manufacture, and he assisted it along
very materially in years past. At the
present time, Mr. J. Latimer is prob-
ably the grower who has been longest
in the business. He related how in 1868
he went to Messrs R. and G. Board’s
plantation, Malungmavel, to _ erect
some machinery for the sugar-making,
and also to put up an arrowroot manu-
facturing plant of a primitive type.
Messrs. Board had ten acres under
arrowroot, and they then got £40 per
ton for it. At that time Mr. Grimes
was also growing some. In those days
the whole of the product went to Mel-
bourne. As sugar was then paying
very well, Messrs. Board relinquished

arrowroot growing, but Messrs. Grimes
and Lahey continued with it, and
soon afterwards some small growers
began to raise the bulb. Since then it
has continued to be a small farmer’s
crop, largely on account of labour con-
ditions making it unremunerative to
pay much outside the grower’s family.
The 200 acres grown this year will
probably produce 250 tons of market-
able arrowroot, worth approximately
£5,000. There are areas of suitable
land with good water available in the
district to widely extend the industry
should the demand justify it, and
no doubt the day will come when much
of the starch used in Australia is manu-
factured in the same district, from
arrowroot, potatoes, maize, and other
products which flourish so well there.—

TROPICAL FRUITS IN COVENT
GARDEN.
According to a leading fruit salesman
in Covent Garden, ‘‘the demand for
rare tropical fruits is increasing.” Not
many years ago the Banana, for instance,
was a rare fruit in England. To-day the
fruits are within the reach of all classes,
being retailed in every greengrocer’s
shop, as well as in the costermonger’s
barrow. Moreover. Bananas are now
imported not only in the fresh, but also
in the preserved state, as well as in the
form of flour. The imports of this
fruitin the fresh state have in a few
years increased by millions of bunches;
at certain seasons special express trains
are provided for the speedy and safe
conveyance to London of West Indian
Bananas arriving at Bristol. A similar
story could be told of Pineapples, which
are now becoming a popular fruit in
England being imported from the
Canary Islands, Straits Settlements,
West Indies and Natal. The culture of
Pineapples in English hot-houses is no
longer necessary, although it affords an
interesting pursuit to those who can
afford it as a luxury. ,
The principal hindrance to the in-
creased importation of tropical fruits
lies in the fact that they decay so readily
after reaching acertain stage of ripeness.
This difficulty is, however, being over-
come to some extent by means ot effective
cold storage on board ship, and by rapid
sea transit. It is to these circumstances
that we chiefly owe such recent intro-
duction from tropical climes as the
Mango(Mangifera Indica), Avocado-pear
(Persea gratissima), Grape-fruit, Cheri-
moyer (called Custard Apple in Covent
Marce, 1909.)
Garden), and Passion fruit (Passiflora).
So far, the demand for these ‘fancy
fruits,” as they are called in the trade,
is limited, and the prices charged for
them are high. As the fruits, however,
become better known and the means of
transport more perfect, it is reasonable
to suppose that they will become popu-
lar, and with a greater demand they
could be sold at lower prices. Itis often
said that the chief recommendation of
most tropical fruits lies in their novelty,
Although this may be admitted in some
cases, there are striking exceptions. It
is true that the taste for certain tropical
fruits has to be acquired, but in the
case of the Tomato, an acquired taste
has been followed by the immense popu-
larity of this fruit. It has been said by
travellers that the three most delicious
fruits in the world are the Pineapple,
Cherimoyer, and Mangosteen (Garcinia
Mangostana). The Mangosteen is as yet
practically unknown in Kurope, but its
good qualities may be judged from the
opinion of Dr. Abel who said that “of
eastern fruits the celebrated Mangosteen
is first in beauty and flavour.” Another
authority declared that ‘‘the flavour of
the Mangosteen partakes of the com-
bined taste of the Pineapple and Peach,
and other equally good but inexpres-
sible qualities.” A peculiarity of this
fruitis that a large number may be

stand why these are always charged for

Covent Garden, the great horticul-
tural market of England, affords a
special opportunity of forming an ac-
quaintance with tropical fruits which are
seldom seen elsewhere in this country.
Rare tropical nuts and fruits may also
be seen and tasted at Shearn’s Fruit-
arian Restaurant in Tottenham Court
Road, where numerous dainty dishes
are made entirely of fruits.
The following sorts have recently
been noted in Covent Garden, and it
may be of interest to give a few of the
particulars concerning these as well as
descriptive notes from my own expe-
rience in the tropics :—
Manco (Mangifera indica),—This ts a
medium-sized or large tree; the fruit
varies from the size of a plum to that
of alarge goose’s egg; very juicy and
often of a delicious flavour; it is very
popular in the Eastern tropics for
desert and for making chutneys. The
fruits seen in Covent Garden are usually
brought from the Canary Islands, and
they are small, They are sold wholesale
at from 4s. 6d. to 6s. per dozen, good
specimens being retailed occasionally at
2s. to 3s. each.

AVOCADO-PEAR (Persea gratissima).—
A small evergreen tree, having fruits
similar to large green pears, sometimes
streaked with red. It isa salad fruit
rather than dessert; the pulp is of the
consistency of firm butter, and is scooped
out with aspoon, being flavoured with
vinegar, pepper, and salt. This fruit
has recently become popular in America.
It is regularly imported to London from
the Canary Islands, and finds ready

GRAPE-FRUIT (Citrus decumana var).
—A globular fruit resembling a large
orange, to which it is allied. It is im-
ported in cases of 50 to 100 or more
fruits, according to their size, and the
fruits are retailed at 6d.to 10d. each.
This fruit comes chiefly from Florida,
where it is very popular. American
residents in London are the principal
buyers. ‘‘ Grape-fruit” is an American
name, the fruit being a variety of the
Pomelo or Shaddock.
POMEGRANATE (Pudica granatwin).—A
shrub or smalltree, with showy scarlet
flowers. The fruits are large and
globular, about 3 inches or more in dia-
meter, sometimes ofa bright red or
orange-yellow in colour. The interior
consists of numerous, closely-packed,
large seeds, which are coated with an
acid, juicy, and astringent pulp. Pome-
granates are imported from South
Europe andithe Mediterranean, occasion-
ally retailed in London at about 6d. to
10d, each or {cheaper.
PERSIMMON (Diospyros Kaki).—A small
bushy tree of the Ebony family, The
fruit is the form of a moderately-sized
apple, bright orange-yellow in colour,
with ashiny rind. The pulp, yellowish
in colour, is ofja peculiar astringent
flavour, for which a taste has to be
acquired before it canbe enjoyed. The
fruit has an attractive appearance, and
it travele well. Persimnions are sent to
Covent Garden from- South Europe,
neatly packed in tissue paper and
shavings, in boxes containing about two
dozen fruitsin each. The fruit sells at
about 8d. to 10d. ‘each.
CHERIMOYER OR CUSTARD APPLE
(Anona Cherimolia).—A large heart-
shaped, dull-green fruit, the rind ‘of
which has the appearance of being
formed of scales. The interior contains
white granular sweet pulp, somewhat
resembling custard. Weekly consign-
ments arrive in Covent Garden from
Madeira during the winter months. The
fruits are retailed at about ls. or more
each, being sometimes sold in West End
Edible Products. 240
shops at double or treble this price.
Cherimoyers do not travel well, and a
large proportion of every consignment
arrives in London in an unsaleable con-
dition.
PASSION-FRUIT (Passifloria edulis).—
The fruit of a pretty climber, of the size
of a large Plum, purple when ripe; the
interior consists of sweet acid pulp in-
termixed with the seed; this, beaten
up with a pinch of bicarbonate of soda,
forms a delicious drink. When ripe, the
vind soon shrivels, giving the fruit an
unfavourable appearance; hence it is
not suited to the Hnglish market.
Trial shipments have been made from
Australia which transport well, but the
shrivelled appearance of the rind is
usually against its sale. In Covent Gar-
den the name “ Passion-fruit” is given
-to another species of Passiflora, which
seems to be the Sweet Cup.
SwEET Cur oR WATER LEMON OF
JAMAICA (Passifloria laurifolia),—The
fruit of this is of the size of a duck’s egg,
the rind being smooth and of a_ pale
amber colour. It is imported regularly
from Madeira, where it is known by the
name ‘‘Maracugia.” The fruits are re-
tailed in London at 6d. to 8d. each. Both
this and the preceding species are some-
times known in Covent Garden by the
name ‘Granadilla,” a term which is
more correctly applied to Passiflora
quandrangularis.
MONSTERA DELICIOSA.—A very hand-
some creeper, with huge leathery, curi-
ously perforated leaves. The fruit is
like a long, green cone, from 8 to 15
inches Icng; it is pleasantly fragrant
when ripe, and partakes of the flavour
of Pineapple ; but the small, black hairs
attached to the edible portion cause an
uncomfortable sensation in the throat.
The fruits arrive in Covent Garden from
the Canary Islands, and occasionally
from Jamaica, and are soldat Is. 6d.
to 2s. 6d. each,
GUAVA (Psidiuin Guava).—A small
tree. The fruit variesin size accord-
ing to variety, but usually it is oval
and about the size of a medium Pear.
It is renowned for making jelly, but
is not popular for dessert. Yet the
fruit has avrived in London from Ma-
deira in increasing quantities during
the last few years; itis said to sell at
2s. 6d. to 3s. 6d. a dozen.
Brazit Nut (Bertholletia excelsa).—
A tall, handsome tree of Brazil. The
fruits are globular in shape and dark
brown, 4 to 6inches in diameter, with
a thick, woody husk; this contains the
hard-shelled seed, which are the Brazil
Nuts of commerce. They are commonly
retailed at 6d. to 8d. a pound, according
toquality. These are used at some res-
tame instead of suet for making pud-
ings.
SouarRi Nut or Butter Not (Caryocar
nuciferun).—A lofty, handsome tree,
with large opposite leaves, native of
tropical’ South America. It produces
large, dark-brown fruits of the size’ of
a child’s head, and similar to the Brazil-
nut fruit. It contains about four large,
kidney-shaped seeds; these have a red-
dish, woody shell, which can only be
broken by an axe or similar implement.
The seeds are the Butter Nuts of shops;
each contains’ a large, white kernel,
which has a very pleasant, nutty flavour.
The nuts are sold in England at about
3d. or 4d. each.
CasHnw Nut (Anacardium occiden-
tale.\—The fruit of a moderate-sized
spreading tree. It consists of two dis-
tinct parts--a much-enlarged. succulent,
green receptacle, at the end of which is
the hard, brown, kidney-shaped fruit.
The latter contains the Nut, which when
roasted is very palatable. These Nuts.
though scarcely known in = Covent
Garden, are imported from India and
the West Indies by afew dealers, who
find no difficulty in disposing of good
samples at 6d. to 8d.a lb. The Nuts
will keep in good condition for several
years it kept dry. Asample ten years
old was exhibited at the recent Colonial
' Fruit,Show at the R. H. S. Hall.
GROUND Nut oR MonKEY Not (Ara-
chis hypogea).—A small, leguminous
annual, which has the peculiar habit of
burying its young pods underground,
where they develop and ripen; these
are forked up when ready for harvest-
ing, cleaned, sorted and exported in
their small, grey, papery shell. They
keep good for a long period, and are
generally seen in small lots for sale in
greengrocers and fruiterers’ shops, the
retail price being about 38d. to 4d. a lb.
Licni or Lircut (Nepheliwn Litchi).—
A celebrated Chinese fruit borne on a
medium-sized tree. The Lichi is usually
of the form of a small Plum, with a thin,
brittle shell of a reddish colour, covered
with wart-like protuberances. It is
filled with a sweet, jelly-like, opaque:
pulp, and is held in great esteem for
dessert and preserves in China. Lichies
are Cou ane in London at ls. to Is. 6d.

Loquat (Photinia Japonica).—A small
Japanese tree. The fruit resembles a
small Apple or Medlar, and is of a sub-
acid flavour, It is sometimes imported
from South Europe.

In addition to the foregoing fruits,
there are those which have become
standard commodities, such as Oranges,
Dates, Figs, &e. Of equatorial or strictly
tropical fruits, however, there yet
remain unrepresented in Covent Garden
@ number which are of excellent quality,
and which could not fail to become
popular in Europe if they could only
be imported in good condition. The
celebrated Durian fruit, for instance, is
itself ‘‘ worth a journey to the East to
enjoy the pleasure of eating it,” in the
estimation of so high an authority as
Dr. Russell Wallace. Notwithstanding
its very offensive odour, the Malays
attribute marvellous properties to this
fruit, and when it is in season they
camp out in families so as to enjoy it. to
the full. The following fruits are all of
excellent quality, and worth the atten-
tion of epicures and dealers in tropical
fruits.
Dorian (Durio zibethinus).—A gigan-
tic, quick-growing, handsome tree, thriv-
ing only in moist and hotdistricts. The
large oblong fruits, which are covered
with formidable spikes, are borne mostly
on the stouter branches, each weighing,
when ripe, several pounds. The edible
portion is the peculiar, fat-like, creamy
substance in which the seeds are em-
bedded. In spite of its odour, Europeans
and others soon acquire a taste for it,
often preferring it to all other fruits.
Locally, the fruits are sold at the equiva-
lent of 1@d. to Is 6d. each. This fruit
has probably never been grown in
Europe; indeed it may be questioned
whether it has been seen there in an
edible condition.
MANGOSTEEN (Garcinia mangostana).—
A medium-sized, slow-growing tree, with
large, handsome leaves. The pretty,
smooth-skinned fruits are of the size of
Apples, perfectly round, and purple
when ripe. Surrounding the seed isa
snowy-white substance, which has a
delicious flavour and melts in the mouth.
The fruits aresold at about ls. to Is. 4d.

on the subject.
Being. deeply anxious for a radical
reform in the whole question of so-called
Edible Producis
‘indentured labour” in Portuguese
African territory, we were most disap-
pointed at the results of the meeting,
results which were entirely due to lack
of judgment on the part of the Chair-
man, who seemed unable to realise that
the converted audience infront of him,
anxious to get home to their dinner or
catch a train, wasas nought compared
to the opposition who went away, we
take it, well satisfied with the results of
the meeting. Kar better that the meet-
ing had never been held than to refuse—
politely, but none the less firmly—under
the plea of want of time to allow an
amendment to be discussed by the
opposition, whose arguments are prob-
ably so weak as to rather tend to bene-
fit us by being advanced, but which can
cause us much trouble by being sup-
pressed. As one opponent stated, no
practical man wants to waste time talk-
ing at the end of a meeting, as the Chair-
man proposed, when the resolution had
already been passed, and it was too late.
People who cannot be inconvenienced by
missing their trains should not pretend
to interfere in these complicated inter-
national labour questions, If they
imagine such matters can be settled by
two hours’ talking on one side of the
question only, they are seriously mis-
taken. As a result of this mistaken
policy of the Chairman, backed up, it is
true, by the majority of the meeting,
unsavoury truths about the state of the
indentured labour in our Colony of
Nels were brought prominently for-
ward.
We can only hope that some indirect
good may come from attention called at
the meeting to the Natal scandal, a
matter that might probably not have
been dragged out so aggressively as it
was, in speeches more eloquent, telling,
and far less tedious than were some of
those devoted to the real object of the
meeting.
We feel sure that every one present
had read the articles and letters pub-
lished on the subject, and attended with
their minds pretty well made up one
way or other, the same as ourselves.
We, therefore, were surprised that
nearly two hours were devoted to
converting thealready converted, whilst
We were most anxious to hear what the
Opposition had to say. We did not
want to be told two or three times over
what wealready knew. We went hoping
to learn some points from our opponents
as to why there is any need to buy San
Thome cacao at all until the state of
slavery is eradicated to the uttermost
end, when our own British Gold Coast

this year, and our total Colonial output
amounts at least to 100,000,000 lb. during
an average year’s crop. Against this
the total consumption in the United
Kingdom for 1907 was only 44,500,000 lb.
(=19,842 tons) raw cacao. Another
question that we hoped to extract infor-
mation upon was, why San Thome
insists on using labour that at present
costs, according to Mr. Nevinson, from
£35 to £40 per head—a labour unwilling
and home sick, and therefore very in-
different whilst alive, and which appa-
rently takes the first opportunity that
presents itself to die? It cannot al-
together be the climate. Can it be that
the treatment is not so rosy in reality
throughout the Island as a whole as it is
reported to be, in one or two cases, on
paper? Whatever the reason is, it must
bea very strong one. What it is we
went to the meeting to find out, but
were unable todo so. So we lost much
time that we could ill-afford, but worse
still, we consider the cause got two nasty
knocks that will take it some time to get
over. If only the conveners of this
meeting had left Mr. William Cadbury
and Mr. Joseph Burtt to fight the battle
alone, this would not have happened.
Everybody at the meeting agreed that
these two are strong fighters with right
and might (in the shape of the trade
boycott) on their side, and this being so
what better champions could the cause
wish for? Why call public meetings,
and run the risk of making our oppo-
nents’ weapons still more formidable
than they are at present.— Tropical Life,

THE FERMENTATION OF CORFEHE.
(By Oscar LoEw, Physiologist.)
The so-called fermentation of coffee
has thus far not been investigated, and
has been defined sometimes as an
“aleoholic fermentation necessary to
remove the saccharine matter.”* “Such
saccharine matter, however, should be
easily removable by simply washing
with water. Upon close examination
the writer concluded that the aim of
the “fermentation” is the removal ofa
slimy stratum firmly adhering to the
parchment envelope of the seeds. The
removal of this is necessary because the
drying of the seed envelope would other-
wise be very much retarded, and because
a bad flavour may finally be imparted to
the seeds by the partial decay of the
slimy stratum during the drying process,
* Cf. Watt. Dictionary of the Economic Products
of India. Calcutta, 1899, vol. 2, p. 476.
(Marcu, 1909.
The process will be explained by examin-
ine ne anatomical structure of the
ruit.
Just below the skin of the fruit and
extending between the enveloped seeds
is a fibrous tissue containing sweet juice.
This pulp, together with the skin, is
easily separated by mechanical means
from the seeds. which are enveloped in a
hard parchment. Adhering to this parch-
ment is astratum of very slimy cells, the
slime layer.
The preparation of coffee for market
requires the following manipulations :—
(1) Pulping to secure removal of the
skin with the adhering tissue.
(2) Fermentation to separate the slimy
layer from the parchment envelope,
(8) Washing away the loosened slime.
(4) Drying the envelope around the
seeds, preparing for the necessary brittle-
ness for the next operation.
(5) Hulling or milling, consisting in
the removal of the parchment envelope,
with subsequent subjection toa fan to
blow away particles of parchment
envelope and silver skin.
The entire fruit is often called ‘‘cherry”
from the similarity of form and colour.
The expression ‘‘ pulped coffee” signifies
seeds in the parchment envelope with
slimy layer. ‘‘Coffee in parchment”
means the product after pulping, fer-
menting, and drying. The ‘ bean”
means the seeds deprived of parchment
and silver skin.
Fruits of red or yellow colour should be
picked for pulping, as only such furnish
seeds of the desired bluish-green colour.
Green unripened fruit containing a hard
pulp and little or no sugar should be
excluded, but such fruit cannot he
entirely avoided since some unripened
seeds will drop off in gathering the
ripened ones.
The fruits are well moistened with
water when passing through the pulper,
which easily separates the skin and
fibrous layer. Attached to the pulper is
a conical sieve (separator) placed ina
horizontal position, which retains the
fruits which have accidentally escaped
pulping, and they are carried back to
the pulper.”
*It has been proposed to dry the pulp and
bring it into commerce as a cheap substitute for
coffee. When pressed well to remove the caffein
and mixed then with molasses it might serve asa
food for hogs. Greshoff holds that the best appli-
cation is as a manure and gives the following
composition in the air-dry state: Caffein, 1:1;
carbohydrates, 23°3; albumin, 7‘6 ; cellulose, 16°) ;
water, 14:9; fat, 3°3; ash, 69. i ee
;
.
‘
ial
Marcu, 1909.]
In order to understand the ferment-
ation process, it must be remembered
that on the surface of all sweet fruits
are a great many yeast cells and bacteria.
When by the pulping the sweet juice is
forced out and spread all over the
separated skin, and over the pulped
coffee, it is not surprising that these
organisms develop rapidly. The sweet
juice not only contains sugar but
also some nitrogenous and _ mineral
matters required for the development of
organisms.
An examination of the skin witha
high magnifying power several hours
after pulping shows numerous cells of
Saccharomyces, which in form resemble
chiefly Saccharomyces ellipsoideus and
sometimes also S. apiculatus.
Numerous bacteria are also present.
Alcoholic fermentation can soon be de-
tected by the vinous odour, and the fact
that the fermentation produces heat ex-
plains why the temperature of such a
heap of pulp rises considerably after a
time. A heap of nearly 30 centimeters
in height showed after sixteen hours a
temperature of 41°C. atan air temper-
ature of 26°C. Later, acetic acid isformed
and the red colour of the skin changed to
a brownish one.
When the pulped coffee, on the other
hand, is examined, a few yeast cells and
bacteria are noticed on the slimy stratum
after one hour, while after sixteen hours
an immense increase has taken place, and
not oaly is considerable alcohol formed
by the yeast cells but also acetic acid by
certain bacteria. Mycoderma and the
mycelium of fungi are occasionally seen.
Litmus is reddened intensely and the
odour of acetic acid readily discernible.
At the same time another volatile pro-
duct is formed in small quantity, which
modifies somewhat the acid odour.
The alcoholic fermentation of the sugar
adhering to the slimy stratum, as well
as the further oxidation of the aleohol to
acetic acid, and finally the respiration
process carried on with considerable in-
tensity by all these organisms, cause a
rise of temperature, depending upon the
depth of the stratum and thetemperature
of the surrounding air. The heaps of
pulped coffee are generally 1 to2 feet high,
In such heaps the temperature was found
after fifteen to sixteen hours to range
from 34° to 42° C. at an air temperature of
25° to 29°C.
The alcoholic and acetic fermentations
proceeding in the heaps of pulped coffee
are, however. not the most essential
phenomena ; the most important point is
that the slimy stratum is separated from
32

Edible Products.
the parchment envelope. It is by no
means dissolved, but merely loses its firm
adhesion and is left loosely spread upon
the parchment coffee so thatit can easily
be washed away by a current of water
and the parchment coffee dried.
Neither the acetic acid nor the enzyme
already present in the slime causes the
separation of the slime layer, as tests
have shown.
Freshly pulped coffee was kept in
dilute acetic acid (about 1 per cent,) at 35°
to 40° C., and another portion in some
water containing a few drops of ether to’
prevent bacterial growth. In both cases
the slimy layer was found still firmly at-
tached to the parchment after twenty
hours. This leaves no other inference
but that a peculiar enzyme dissolving the
adhesive substance (a carbohydrate ?) be-
tween the parchment and the slimy
stratum was furnished by the bacterial
growth, or, what is less probable, by the
yeast cells.
The ‘‘fermentation” should not take
longer in Porto Rico than fifteen tu
twenty hours, while in some sections
of Central America, as Guatemala, it
must be carried on for two days.
Undue prolongation of the ferment-
ation must be avoided, as otherwise a
brown colouration of the parchment and
of the seeds is produced and the seeds
further acquire a disagreeable odour—
two circumstances which render the pro-
duct unfit for the market.
After the fermentation and washing
the parchment of the coffee is readily
dried, either on cement floors exposed
to sun and air, or better in rotating
eylinders through which warmair passes.
At a certain degree of dryness the parch-
ment becomes brittle and breaks easily
in the milling process, which thus re-
moves the parchment envelope and silver
skin from the seeds. In fact. the milling
must be done while the parchment is
still warm.
This milling isin many cases done in
London, and not in the country where
the coffee is produced. Better preser-
vation of shape and colour of the bean
has been observed, when the latter is
protected for atime by the parchment
envelope. The cost of transportatior is
in this case a little higher, but it does
not come into consideration, as from $2
to $3 more has been realized per hundred-
weight for eoffee thus treated than for
that cured in Central America.
In reviewing the so-called ferment-
ation of coffee, the conclusion is inevit-
able that alcoholic and acetic ferment-

ations are not of direct benefit, but
only indirectly, inasmuch as heat is
thereby produced which supports the
action of a body (enzyme) furnished by
the bacteria, which dissolves the adhesive
substance between parchment envelope
and slimy layer.—Philippine Agricul-
tural Review, Vol. I., No. 9, September,

MANIOC OR CASSAVA.
By Epwin B. CoPpELAND.
(Concluded from page 24.)
_ The best time at which to harvest
the roots for starch manufacture ought
to be very carefully determined locally
wherever the manufacture of starch
is an industry. In the Straits Settle-
ments the Chinese are said to wait until
the roots are eighteen months old, while
the European planters harvest their crop
in about ten months. In determining
the most popular age, various factors
must be considered—the weight of roots,
their starch contents, and the rental of
the land, or its productivity if replanted,
being the most important. The weight
and the content of starch depend upon
the variety grown, the climate and
season, and the cultivation. The de-
pendence upon variety and season is
well shown in the following table repre-
senting the yield of five native Jamaica
varieties. The 1907 crop had an excep-
tionally wet season,

There were five other varieties in the

eighteen months old was over five tons
per acre. As between twelve and
eighteen months, the general result is
that tor the sake of greater yield it is
decidedly better to leave the plants a
year and a half. Conditions in the
Phillippines are the same. While the
percentage of starch, a scant ten in the
roots of 5-month-old plants, reaches
its maximum at about ten months, the
most rapid growth of the roots is then
only well under way. The percentage
of starch begins to decrease, at least
sometimes, before the plants are twelve
months old, but the total amount con-
tinues toincrease rapidly, and the slight-
ly increased woodiness does not seriously
‘interfere with its extraction.
When manioc is raised for food, the
roots are dug like potatoes for use as
wanted. When it is grown on a large
scale, the plants are sometimes pulled
by hand from very light soil, but the
work is done much more easily by the
use of a lifter. Thesimplest lifter is a
straight wooden stick, 2 or 3 meters
long, strong enough so that it will not
break, which is used as a lever. The
fulcrum end rests on the ground, and
is provided on the underside with an
old spade blade or some other flat kody .
to prevent its sinking in. Near the ful-
crum end is fastened a hook or other
grappling device. By lifting the long
arm of the lever and shaking the plant
is pulled out of the ground reasonably
free from adhering soil. If some roots
break off they are dug individually.
When the field is in sufficiently good cul-
tivation to permit ploughing, a furrow
is run alongside of each row, making
the roots pull up more onellg and with
less breaking.
The yield of manioc has been the
subject of day dreams. Semler, not too
positively, cites a New Caledonia plan-
tation whose yield in two years ranged
from 25 to 250 metric tons of roots per
hectare. Reports in German Hast Africa
sent to the Experiment Station at
Amani range from 2'5 to 225tons. Such
reports as these larger ones must be
duc to mistake or misunderstanding, or
_to computing the yield per hectare
from that of a few exceptional plants.
Single plants indubitably have produced
twenty-five kilograms of roots, and
10,000 such plants on a hectare would
yield 250 tons. But such yields do not
occur. The yield of some notably good
Jamaica varieties has already _ been
given. Twenty-five Colombian varieties,
grown in Jamaica in 1907 produced 3'1 to
13°3 English tons per acre. From Florida
there have been reports of 30 or 40 tons
Marcu, 1909. |
per acre, and the average near the Lake
Mary factory, where the figures should
be reliable, has been given as 9 and 10
tons ; but the average cropin the United
States is not believed to be more than
5 tons. In Pondicherry 5 metric tons is
the maximum crop expected from a
hectare of well-manured plants irrigated
five or six times a month during the dry
season. In Ceylon and Java the yield is
expected to be above 25 tons per hectare.
A test crop ten months old at Hue was
14:44tons per hectare. There are no
data as to the actual yield of any con-
siderable acres in the Philippines, but
from the unanimous opinion of growers
and from our own observations and
weighings of apparently representative
plants, itis our opinion that 25 tons per
hectare is a very low estimate of the
yield fairly to be expected from a crop
a year o1 upward old.
Many analyses showing the starch
content of manioc have been published,
but it is not worth while to copy them
here. Data onthe best Jamaica varie-
ties have already been given. The
matter of business interestis not the
absolute starch content of the roots, but
the amount which can be obtained by
practical manufacturing methods. This
of course depends on how much isin the
roots, but to a greater extent still upon
the method used in its extraction, and
the thoroughness with which it is worth
while to extract must be settled locally
according to the value of the starch and
the cost of producing the roots. For
this reason the same methods are by no
means to be recommended for all parts
of the world. The highest starch con-
tent Ihave seen published is 36°5 per
cent. ina Colombian variety grown in
Jamaica in 1903 and called ‘‘Governor
Hemming”; four years later the same
valiety contained only 30°17 per cent.
By commercially feasible treatment we
obtained here more than 31 per cent, of
air-dry starch, in one test.
STARCH MANUFACTURE.
The first step in starch manufacture
is always and everywhere the same, the
roots are washed clean. If any dirt
finds its way into the mill, it will stay
with the starch through the whole
process of manufacture, and be init at
the end. A very little dirt destroys the
perfect whiteness of the starch, and only
perfectly white starch can be soldat a
good price. The washing can be done
by hand or in a mechanical washer.
Mechanical washing of most roots and
in most places is much the cheaper, but
the great and irregular size, of manioc
roots offers some difficulty. When the
251
Edible Products,
roots have been thoroughly washed, it
is customary to peel them removing the
bark and cortex which contain no starch
and atthe same time to get rid of any
last particles of dirt. If the roots are
kept moist until decay begins the cortex
will slip off readily in the hands, but
this course is not to be recommended.
If the roots are perfectly clean the
removal of the bark and cortex is un-
necessary, for they contain nothing
which discolours or mixes with the
starch. :
The starch in the roots is contained in
the cells of the pith. The starch grains
are very minute, decidedly smaller than
those of potato starch, and the cells
containing them are also smaller. For
this reason and because the roots are
more woody than the tubers of potato,
it is more difficult.to extract the starch
completely. The walls must clearly be
broken to let the starch escape; the
starch in any unbroken cell is lost with
the fibrous part of the roots. The walls
are broken by decay or by scraping,
rasping, or crushing the roots.
The practice of letting the roots decay
has been in use among the poor Chinese
of the Malay States since about 1891
in making a low grade of tapioca,
but not in the manufacture of saleable
starch, A Dutch writer, de Kruijff
(Teysmania, 1906, No. 8), has recently
stated that by letting the walls decay it
is possible to secure the starch very
completely and of as good quality as is
obtained by other processes. Anyone
adopting this method will wisely try
it at first on a very small scale,
The old Chinese method in the Straits
Settlements, when that district first
took a prominent place in the manu-
facture of starch and tapioca, was to
wash the roots, peel them, wash them
again, grind or crush them between
rollers, strain out the fibrous part of the
pulp with asieve which permitted the
starch to pass through with the water,
let thestarch settle, draw off the water,
and wash until clean and dry. This was
all done by hand. In the factories of
Europeans steam power is in use and the
roots are pulped by scraping.
Elaborate machinery for starch man
facture has naturally been developed
special adaptation to corn and _ potatoes.
The first attempts at manioc starch
mills on the same scale were made in
Florida about a decade ago. The Lake
Mary factory. put in potato-starch
machinery, and with it was unable to
get more than 20 per cent. of the starch
from roots containing fully 27 per cent.
They have since made improvements—
Hdible Products.
circumstances and the will of the planter
which at least, for the most part, should
be used in potato-starch manufacture as
well—by which, with cheaper plant and
at a lower running cost, they get nearly
or quite 25 per cent. The new process is
the work of Archbold, who published a
brief description of it in the Journal of
the Society of Chemical Industry (1903,
p. 63-66), The washed roots are scraped
and milled. The pulp is then driven
upward by a stream of water against a
wire-gauze diaphragm, through which
the starch and water pass. Instead of
having the starch settle in still tanks,
the milky mixture of starch and water
is piped to near the bottom of a tank
which has the form of a large inverted
cone, in which the mixture flows up-
ward. Asthe cone widens upward the
rate of flow decreases until it becomes
so slow thatthe starch settles against
it; only the dirty water flows off at the
top, and the starch is drawn off below.
To insure the quality of starch, there
is one condition more important than
all others—an abundance of clean pure
water. The pulp must be thoroughly
washed to separate the starch from the
waste, and then the starch needs from
two to sometimes as many as eight
washings. If there is any evident im-
purity in the water. the starch may be
relied upon to take it up. It is of course
expected that the starch will be free
from all particles of cellulose or wood ;
this is easily managed by the use of a
sound fine sieve, whether of cloth or wire.
The completeness with which the
starch can be extracted depends on how
completely all the celisare broken, In
the fotato-starch factories and in
Florida, the comminuation of the roots
is accomplished by a rotating cylinder
set with blades with saw-like edges. A
cheaper mill can be made by filling a
sheet of iron or tin with holes by
driving a nail into it, driving it
always in the same direction. The
sheet is then fastened around a cylinder.
I quote from Bulletin 106, Bureau of
Chemistry, United States Department
of Agriculture, page 28 :—‘‘ A two-horse-
power gas engine was used for grinding,
the mill consisting of a revolving drum
covered with a sheet of roofing tin punc-
tured to make a grating surface. Over
this a hopper was arranged, the whole
resting on a suitable frame. This mill
cost, when complete, with shaft, boxings,
and pulley, $10, and would grind. one
ton of tubers in one and a half hours.”
The quality of the work of such a mill
depends onthe fineness of the projec-
tions and the speed of the rotation.
cylinder with fine teeth will not
work as fast as one with coarse
252
[MaRcu, 1909.
teeth; but it will not use much more
power in milling a given weight of roots,
and for the sake of greater capacity it
has only to be made longer. With such
a cylinder whose projections are more
than one millimeter high, not more than
24 per cent. out of 381 is likely to be ex-
tracted. With a cylinder whose projec-
tions are less than 0°5 millimeter high
it is as easy to get 3 or 4 per cent. more.
In the Philippines the roots can be
produced at so low a cost that the use of
expensive machinery for the extraction
of the last possible percentage of starch
would be foolish. The money that would
be spentin the purchase and operation
of such machinery will give a much larger
return in starch if it is spent in producing
morerocts. The process of manufacture,
as it can most profitably be carried out
here, reduces itself to this :—
1. Cleaning the roots perfectly.
2. Milling them on the rough cylinder
just described.
3. SCREENING THE PULP.—This is sim-
ply and thoroughly done by running it
through a trough with sieve bottom of
cloth or wire. To make it screen well and
quickly, the trough should be shaken and
fine jets of water should play upon it.
4, SETTLING.—Concrete tanks will,
without doubt, prove most* economical.
For fast work in washing they should
be shallow.
5. WaASHING.—After the water is run
off, preferably by means of cocks in the
sides of the tanks, the starch must be
washed with clean water and allowed to
settle, and this must be repeated until itis
perfectly white. To keep the starch from
making a hard sediment and not being
washed except on the top, each tank
should have a stirring paddleor set of
paddles which will best be worked by
hand. Care must be taken that no dirt
can fall or blow into the tanks.
6. DryiIna.—How this is done will
depend upon local conditions, but wil
usually prove unsafe to rely upon the
sun. If adrying house is used, it must
be absolutely free from smoke and dust.
CoOsT OF PRODUCTION.
It would not be without interest, if
it were possible, to make a detailed
statement in support of theassertion that
manioec production in the Philippines
is remarkably cheap. But as soon as
such statements become really detailed,
they cease to have more than a very
local value, and fit only the case of the
individual whose experiments they re-
present. The cost of management and
the items chargeable as interest, deterior-
ation, and rent depend so entirely upon
Marcu, 1909.)
that a general statement of them is
valueless. Government land suitable for
manioc culture is available in most parts
of these Islands, and can persumably
be leased for 50 centavos per hectare,
per annum, or bought at10 pesos per

CLEAN. WEEDING ON TEA AND
RUBBER ESTATES.
————-
SOME JAVA INSTRUCTIONS.
We publish on this page a most interesting
document of instructions to Managers on certain
tea and rubber estates in Java, which reaches us
through the hands of a prominent Ceylon planter,
who, in turn, had it sent to him from London.
We are not permitted to publish the name
attached ; our correspondent had no authority
to do this. He tells us he quite agrees with all
the Java authority says as to the ruin of estates
by clean weeding ; he is old enough, he adds, to
remember planters who said of coffee that short
crops came in with clean weeding. Mr. Kelway
‘Bamber (as far as our informant understands him)
condemns clean weeding in the fullest.and most
comprehensive manner ; and although, to a cer-
tain extent, it must be allowed on tea estates to
work the tea properly, it is the worst of folly to
indulge in it in rubber estates. This Ceylon
planter saw quite recently a gang of between 300
and 400 coolies in lines, armed with mamoties,
scraping a steep hill sido of a new clearing.
The loss of soil resulting from such opera-
tions is greater than all the manure that could
be applied would ever compensate for, He is
trying partial weeding himself ; and where it is
properly and reasonably done, he has no hesi-
tation at all in saying the growth of rubber is
greatly superior to clean-weeded fields, As cer-
tain eminent planters—he remarks—make clean
weeding a kind of fetish, he has no wish to start
a discussion which might drift into personalities;
but the opinions we now publish are important,
and we have pleasure in giving them full promi-
nence and expressing our readiness to publishing
anything on the other side, that of the clean-
weeders,

TO JAVA MANAGERS AND ASSISTANTS,
Gentlemen,—I forward for your perusal en-
closed extracts from Reports of Mr Kelway
Bamber, the well-known Ceylon Expert in Soils
and General Tropical Cultivation made on
and Estates belonging to the
Java Rubber—————OCo. this month, as I
feel that his remarks express in a few words so
exactly the advantages of asystem which I have
urged upon all those working under me for
many years with excellent results where they
have been followed, whilst where the opposite
has been the case the system of keeping un.
dulating land or hilly ground clean by ordinary
‘neored’ work with the ‘Parang,’ and similar
tools has resulted with just the opposite effects,
I maintain, and have always maintained, that
the scraping of the soils clear :—
(a) Means loss of the best soil within a given
amount of years varying in accordance with the
depth of the good soil, heaviness of the rainfal)
and the frequency with which this treatment
is done.
(b) Encourages grass weeds such as ‘evreh’,
djukoet pait, etc., to the detriment of the better
and more succulent class of weeds,
(c) Is the most expensive form of upkeep
there is, aS cutting all the tops of the Kureh
plants just about level with the ground has the
same effect on itas pruning has on a Tea bush,
e.g. that the growth of the weed is strengthened,
whilst far more tops come up than there were
before the treatment.
If only of those who are in charge of Estates
would get firmly into their heads that theappear-
ance of an Estate at any given moment—that is,
whether it is looking beautifully clean or rather
dirty—is aemall matter compared with the
ENORMOUS IMPORTANUE OF PRESERVING THE SOIL
of same which after all isone’s Capital Asset, loss
of which must naturally mean deterioration af the
282
property, diminution of Crops, and depreciation
of that Kstate. The first and the first and fore-
most point every Manager should keep before him
is the retaining of the best part of the soil, for a
maximum period, from the time the land is
cleared, even if doing so forfeits the compliments
ofa V.A. or visitors’ congratulations, upon the
cleanliness of the Hstate—which may give at the
moment much satisfaction to him, compared
with criticisius to the opposite offect.
J know of Estates in the close vicinity of
where I have lived most of my Java career
where the Tea crops are reduced to a minimum,
almost entirely because the best part of the
soil as long ago been washed down to the
Ravines through the fault of former Managers,
who thought of nothing except pleasing their
V. A. on the ground of having the Estate beauti-
fully clean. he result of thisis that prolits are wil
and the shares standing at a hopelessly low price,
there being practically no soil left to grow the
crops which are required to make such profits,
If gentlemen will only give themselves the
trouble of making a good experiment of the two
systems ona fairly targe scate, they will see, Jam
sure, the difference and results—within a year
—for themselves. ThesystemI advocate is dig-
ging or forking out all ‘‘Hureh” ‘‘Casso” and
injurious grasses, and leaving the harmless or
rather beneficial weeds such as ‘‘Sintrongs’’,
““Djukoet Mingoe”, to grow up fairly plentiful
but not to such an extent as to impede in any
way the cultivation in question. When these
weeds begin to get out of hand, cut them down,
but at a couple of inches from the ground, so that
THEIR ROOTS REMAIN
AND PREVENT DISPLACEMENT OF SOIL
when you get the heavy rains, But the
plan of taking out systematically and wherever
they show themselves the Eureh and grass
weeds by means of ‘‘garpee djodjo” (forking
out grass weed wherever they appear, as opposed
to forking a garden right through) a system
which should be at a cheaper cost per Bouw
every time that coolies employed for this work
go round the Estate until the cost is reduced to
a trifle, must be systematically, and at regular
intervals, followed.
In this way you are constantly decreasing
your injurious weeds, and encouraging harmless
and beneficial weeds, which in themselves keep the
first-named out of the gardens.
Once a year or more if necessary and if funds
are available the whole of these
BENEFICIAL WEEDS SHOULD BE DUG RIGHT IN
THE EARTH, BEING SIMPLY TURNED OVER
in big clods. After this treatment you will
see that the injurious grasses are slill further
diminished, and the character of the weeds which
come up still further improved, until you get
a system which combines the advantages of
preserving soil, greenmanuring and thorough culti-
vation of soil, which—it is impossible for any one
who has given much attention to the results of
the different systems to doubt—is entirely to the
benefit both of the soil itself, and of the growth
and health of the product under cultivation,
{ will be extremely obliged if all gentlemen
to whom this letter is addressed, will

AND SYSTEMATIC TRIAL
of above ; whilst, if they wish it, they might
try the results of the other system of keeping
the gardens clean by ordinary weeding (ngored)
which is still the most prevalent one, on most
Kastern Estates in the Preanger., And I will be
extremely obliged, if they will keep an exact
record of the frequency with which the dif-
ferent kinds of treatments to the grounds
are given giving cost of same each time
and general results at the end of the year,
both as regards the appearance of the soil,
and growth and general healthiness of the trees
and bushes, being cultivated. Such informa-
tions orconclusions I am pleased to hold at the
disposal cfany of the gentlemen working on
Kstates [ am connected with, and also to hear
their opinions upon what L have written above.
in my opinion the question of the best form of
upkeep in the long run for our Java soils, on
steep or even undulating land, is far and away the
most important one which the would-be suc-
cessful planter of the future has to decide upon.
One has only to go through old hilly gardens
on Estates in the Preanger, where the Coffee and
Kina gardens were for years and yearskept clean
by the ordinary ngored system, and where only
with the greatest assistance and heavy cultiva-
tion, can even a strong product like the tea bush
be got to give a fair production, and then to go
into a bit of unopened forest, joining same
gardens, and with exactly the same lie of land
and originally the same soil, to realise what a
cruel destruction of property and loss of Share-
holders’ money has been effected by this,
IN MY OPINION, MOST DAMNABLE OF SYSTEMS
by which such estates have been kept beautifully
clean in the past to the satisfaction of visiting
agents but at a cost of the value of the Share-
holders asset. The same results can be seen on
very many of the steeper Tea Estates in Mas-
keliya, Dikoyaand other steep districts of Ceylon.
Hoping those to whom this is addressed will
give this matter their close and earnest atten-
tion.—I am, Gentlemen, yours faithfully, &c.
MESSRS. NicMEEKIN & CO.’S
ANNUAL TEA REPORT.
Messrs. McMeekin & Co.’s annual report on
the tea trade is usually the last to reach us
from London ; but itinvariably more than makes
up for the lateness of its appearance by the
comprehensiveness of its scope and the novelty
of its contents. Points of very immediate
interest to the tea trade are carefully investi-
gated and presented by Messrs. McMeekin,
which as arule are ignored by the majority of
tea firms in their annual reports. Following
this will be found the full text of Messrs.
McMeekin’s deliverance on the tea trade of 1908,
which we are sure, all our readers will consider
well worth reproduction in the 7.A. The report
deals with the position of the industry in all pro-
ducing countriesaud it will be noticed that Messrs
McMeekin’s remarks on Java tea bear out what
we stated in alluding to the official statistics of
tea production in Java we published last month.
Java teas, it is pointed out, have made more
and Magazine uf the Ceylon Agricultural Society.
progress within the year than those of any other
growth. The trade in London, itis true, has
made very little progress ; but the teas are laid
down so cheaply at the outports that they now
form a considerable proportion of the trading
in certain centres, thus seriously restricting the
possibilities of business in other growths. Deal-
ing with the ‘‘ Purity of Tea,” the report subse-
quently states that ‘‘ the only growth showing
a general improvement is that of Java.” The
prevalence of ‘‘ stalks” in Indian and Ceylon
‘eas has, we are informed, caused much com-
plaint from country and foreign buyers. Java
Teas being, so far, much freer from anything of
the kind, have frequently received a preference
in consequence. This isa very clear and definite
indication of one direction in which British pro-
ducers are being beaten by the Dutch Colony.
The fault complained of can be remedied
and all planters both in Ceylon and India
ought to make ita point to see that’ stalky”
tea isnot in future placed on the market.
With regard to future prospects Messrs.
McMeekin regard as the gravest danger tothe
industry a large yield from India during 1909,
In addition to the report we reproduce else-
where, Messrs McMeekin publish a table showing
tea statistics for six calendar years and a chart
with a statement showing the alterations in the
relative proportions of different growths of Tea
consumed during 22 years ended 31st December,
1908, the variations in the London average prices
for Indian teas, and the changes in rate of Duty.
TEA IN 1908.
(Messrs, McMeehin & Co.’s Review.)
The reports upon the heavy lines of trade of all
kinds during the year are generally unsatisfac-
tory, and Tea has, to a certain extent, shared in
the bad results. The financial convulsion which
shook New York in November, 1907, and dis-
turbed the money markets of the world, had
prolonged after-effects upon nearly every im-
portant description of business, and the fact
that Tea was not more unfavourably influenced
is strong testimony to the sound and general
position of the trade.
PRODUCERS.
A remarkable change came over the character
of the demand during the year, and the common-
est grades, which for a long time had been kept
at a high level of price as compared with those
considered to be worth intrinsically much more
money, were in lessened demand. Prices of the
former consequently fell, slowly but surely,
throughout the first eleven months of the year.
Coincident with the neglect of the common
grades there came an improved demand for
better qualities and a widening range of prices,
The averages of prices for both Indian and
Ceylon Teas showed some decline over the high
level of the previous year, but itis probable
that the year’s working was more generally satis-
factory to the whole body of producers. The
phenomenal profits made by Bheel states from
enormous out-turns of low grade stuff will not be
s0 conspicuous as they wore, but, on the other
hand, more encouragement will be given to those
288
producing Teas of good quality. The turning
fromthe demand for mere lowness of price to a
requirement for quality is a highly satisfactory
feature that should receive every encouragement.
The estimated value of the debentures and
shares of 170 Tea producing companies repre-
sentative of India and Ceylon was at Ist
November, 1908, £20,000,000 as against
£21,600,000 twelve months earlier, Having in
view that an average fall of approximately %
of a penny per pound was recorded on the total
yields, itis surprising that the capital difference
was not greater, looking to the reduced dividend-
paying power. The shares, however, are gene-
rally firmly held by permanent investors,
DistRIBUTORS.
Following a succession of difficult years, that
just gone has been one of the worst on record
for those who try to make a living out of mer-
chant business in tea, The large wholesale
dealers, although working on lower values and
a lower Bank rate, have again had to face serious
losses from depreciation in stock values, the
long continued decline in the lower grades
rendering profitable business impossible, The
smaller country dealers and the retailers have
been faced with the competition of the multiple-
shop concerns and it has frequently been of an
exceedingly unfair character. Gross misrepre-
sentation in the way of lavish advertising as to
quality and value is very hard to deal with, but
here and there independent traders have made a
good stand for the old-fashioned honest methods
of describing goods. The failures among retail
grocers have for the year been unusually
numerous, and the wholesale trade has suffered
accordingly. Even the multiple-shop companies,
although several of them have made numerous
additions to the number of their branches and
in some cases added seriously to their working
costs, have not all been able to maintain their
previous rates of dividend.
CONSUMERS.
The general lack of prosperity throughout the
Kingdom and the large percentage of unemploy-
ment known to exist in many districts had little
obvious eifect upon the consumption of Tea,
The quantity taken actually showed an increase
on the previous year of atout 14 million lb. and
was again the highest cn record. Allowing, how-
ever, for the usual natural increase in the popu-
lation, a small Cecline in the quantity consumed
per person is shown,
In the matter of consumption Tea compares
favourably with most of the large lines of goods
figuring in the Board of Trade returns and appar-
ently itis likely to be one of the last items to
be prejudicially affected by adverse industrial
conditions.
Inpran TEA,
Owing to the continued increase in direct trading with
India, importations into London again showed a decline
on the previous year. ‘fhe offerings in auctions there, were,
however considerably heavier, but the difference is explained
by the reduced extent of selling forced on the producers in
December, 1907, in consequence of ths abnormal financial
position then existing. In the earlier months of the New
Season the demand in Calcutta for several of the large
direct outlets was not so strong as in 1907, and conse.
quently more tea in proportion fo the total yield Weg
284
shipped to London (about 8,600,000 lb. increase on the pre-
vious season’s figures were received there within the old
year). Tbe demand improved towards the close of the year,
doubtless in consequence of the considerably lower range
of prices established in September and October. The
quantities offered in the Calcutta auctions from the com-
mencement of the New Season till the close of the year
were about 2,000,000 Ib, Jess than in 1907.
The total production of the whole of India for 197 was
reported as 248,000,(00 lb., or an increase of 7,0uu,000 lb, over
the very large total of 1906. It is impossible at present to
estimate closely what the figure for 1908 will actually result
iv, but in all probability the increase will be abcut 5,000,000
ib, giving a total of 256,060,000 Jb. The recorded exports
from India in 1907 were 228,000,000 lb., and it is considered
that a serious discrepancy exists in the returns of yield,
as it is thought improbable that the internal consumption
of India would equal 20,000,000 Ib. The principal develop-
ment in production has occurred in Assam, where a more
favourable position as to labour is influencing yields.
It is fortunate for all concerned in the business that the
weather conditions were somewhat adverse, and that,
therefore, the very much larger yield whichat one time
was expected was not harvested.
Cryton TEA,
Although further Teais now to a moderate
extent being planted in Ceylon, it may safely be
assumed that the planting during say four or
tive years back was mostly done inrubber. As
rouch of the rubber was actually planted among
the existing Tea bushes (a system not calculated
to conduce to the rapid and successful growth of
either product) the development of the rubber
trees was bound gradually to tell upon the Tea
bushes and ultimately to render their continued
culture an impossibility, There is little doubt
that the influence of rubber on Tea yields is now
beginning to be felt, and that it will soon show
itself more definitely, while an increased yield
from new Tea planting is still somewhat remote.
It may be assumed that the satisfactory prices
ruling for Ceylon Teas led to as free plucking as
possible; but, notwithstanding that, the total
crop for 1908 showed a decline on the 1907 figures
of about 2,000,000 lb. As other countries took,
in the aggregate, about as much asin the pre-
vious year, the deficiency in yield necessarily
came off the shipments sent to Great Britain. The
shortcoming made room for part of the excess
from India and materially helped to steady aud
enhance the London market for Ceylon growths.
The Home Trade consumption of Ceylon Tea
was a record for quantity within the year, viz..
92,960,000 lb, but in 1900 the igure approached
closely to that, being 92,470,000 lb. The share
of the total was, however, in the latter year 37
per cent, while in 19(8 it was only 333 per cent.
{ft had, however, in the interim been down to
30% per cent. Thereturns to Ceylon producers
during the year have apparently been scarcely
s0 favourable, onthe average, as those made
upon Indian growths. The ratios of prices to
those of 1907 (taking Colombo and London mar-
kets together, as compared with Calcutta and
London markets) were less favourable; there
was areduced instead of an enhanced total crop
and the high cost of rice was more severely felt
than in India.
Java TEA,
These teas have made more progress within the year than
those of any other growth. ‘The total quantity exported
from Java within the 12 months ended 30th June, 1908, was
32,792,000 1b against 24,950,000 1b in’ the corresponding
previous 1: months. They have gained also in the way of
improved quality and in increased consumption in all the
larger outlets, viz. Holland, Great Britain and Ireland,
Russia, Australia aud Hersia. The trade in those through
London has made but little progress on the average of re-
cent years, but they are so cheaply laid down at the out-
ports baat fuey Bow fm a Gensiderable proportion of the
The Supplement to the Tropical griculturist
trading incertain centres, thus seriously restricting thid
possibilities of businessin other growths. It will be seen
trom the statistics that the British home consumption
showed an increase ot nearly 50 per cent. in five years, ‘The
reports of marvellously cheap labour, unusually rich soil,
heavy yields and consequent low costs of production have
attracted attention to the desirablity of the island as a tield
for investment in tea growing, and names hitherto identi-
tied with tea production in British dependencies only are
now becoming associated with Java production. This may
be in individual self-defence, but any large development in
that island cannot fail to affect prejudicially India and
Ceylon, and may lead to a recurrence of the outcry for
protection for a British industry, formerly so frequently
raised against China tea.
CHINA TEA.
Notwithstanding the advertising and the Jarge amount
of press publicity it has received, China ‘ea has fallen
back somewhat in British Home Trade use within the
year. ‘The considerable increase, relatively speaking,
in the imports has only led to a piling up of unsale-
able stocks of such a low character that while com-
plying with the Government standard of chemical purity,
they would not be admitted to the United States of
America or Canada, where a more detinite restriction
is placed upon what may be sent into consumption.
Those importations include a considerable increase in green
teas, a class that is almost wholly taken for export. They
probably came to London because of temporary derange-
ments at other points, and, judging from the relatively
high re-exports of China tea, a considerable proportion of
the increased arrivals in that class has passed out of the
stock, leaving an accumulation consisting chiefly of China
siftings that can only be worked off very slowly in small
percentages of the cheaper blends retailed in the home
trade. Although the business of importing China teas to
London has now been,reduced to a very small compass, its
volume during the year was sufficient to cause serious em-
barrassment to some of those engaged in the business.
Owing to high costs and bad realisations the results were
disastrous, and it is reported that considerable losses were
made upon teas sent direct from China to the other markets
that take larger quantities.
Those responsible for the modern efforts to boom good
China tea would probably carry with them the respect and
goodwill of the producers of other growths, and of the dis-
tributive dealers also, were they less disingennous in
use made ofabnormal statistics. It can do no goodia the
long run to give publicity to misleading figures,
JAPAN AND Formosa TRA.
Vhe latest official statistics issued by the Department
of Finance in Tokyo show that the yield of lea in Japan
during 1906 from 122,500 acres was 58,260,(001b being a
decline since 1897 of 2),000 acres and 12,000,000 1b. The value
of the exported quantity was stated to be £1,036 000, he
yield in Formosa during 1906 was 15,168,000 lb., ur a decline
of 9,060,000 1b, since 1878, The United States of America
took a very large proportion of all the quantities exported
from both places,
ForREIGN TRADE.
The re-exports from the United Kingdom
have again shown a decided falling off, and are
back to about the level current prior to 1906,
With the exception of a trifling increase in Sep-
tember, the decline was continuous during the
first 10 months of the year, but in November and
December there were gains amounting to nearly
2,900,100 lb., doubtless arising from the lower
scale of prices ruling in London. With the excep-
tion of Canada, Indian Tea lost ground in allthe
principal outlets. Ceylon, while again losing
heavily to Russia and in the general export
trade, made headway in business with the United
States of America, Canada and European coun-
tries other than Russia. The loss of trade in
Tea between London and Russia is directly
attributable to the policy of retaliation pursued
by the latter because of the exclusion of Rus-
sian Sugars from the English market by the
Brussels Convention. Although the barrier has
now been removed, the trade does not appear
to be returning, except in a casual manper,
and Magazine of the Ceylon Agricultural Society.
Calcutta and Colombo taken together have
not, any more than London, gained during the
year in their tracing with the rest of the world,
as compared with 1907. Statistics areas yet in-
complete, but it appears as if Russia would take
about 2 million pounds less; Australasia is
taking about 4 million pounds less ; Canada
and the United States of America together take
an increase of 2% million pounds, while there
is a general increase in places not specially
named of about 25 million pounds,
SuHips’ Srores,
The quantity of Tea absorbed for the use of
passengers and ships’ crews has increased in
proportion to the Jarge development of tonnage
afloat in merchant and Government vessels,
but it is unfortunate that so little attempt is
yet made to supply tea better in quality and in
methods of infusion for the useof those who ‘‘go
down to the sea in ships.”
Pcuriry or TEA,
There was a considerable increase in the
number of tea samples analysed by authority
of the Commissioners of Customs during the
last completed Customs’ year, which doubtless
arose from the free importation of China tea of
at least questionable purity. Only 33 packages
were condemned as unfit for food, while 2,070
were refused admission for Home Consumption.
The percentage is very small relative ‘to the
whole importation and probably a large portion
of the rejected teas consisted of packages
damaged in transit.
The general character of all tea arriving from
abroad does not tend to improve, and it would
appear that the same amount of care as for-
metly is not exercised in the preparation. The
only growth showing a general improvement
is that of Java. The prevalence of ** stalks”
in Indian and Ceylon teas has caused much
complaint from country and foreign buyers, and
Java teas being, so far, much freer trom anything
of the kind, have frequently received a pre-
ference in consequence,
Tue Tra Dury.
Fortunately for the trade, there was about
a minimum of disturbance of regular trading
conditions arising from anticipation of Budget
possibilities, and it is to be hoped that 1909
will be allowed to pass in an equally placid
way. Unfortunately, attempts are being made
by professional scaremongers to work up an
agitation about a possible increase of auty, but
they are unlikely to attract serious attention.
PRosPEcts,
The New Year started with a stock on hand in
all the bonded warehouses of the United King-
dom of 128,393,000 lb., against 124,712,000 Ib. at
the end of 1907. The difference may be taken as
roughly representing the dead-weight of almost
unsaleable China sorts now lying in London. Uf
the stock, however, probably somewhere about
5,000,000 Ib. more than at the same time last
year are held by the buyers and not by the im-
orters. The moderate prices ruling in November

and itis known that some prominent coucerns.
gan now stay out of the market for months,
285
They are unlikely to pay the recently made ad-
vance on lower grade teas until their cheaper
stotks are exhausted. Much of the buying in
December was not for immediate requirements
but merely to guard against the risk of another
seriousadvance in tea for price. A rise actually
resulted, but, as it did not come from an actual
demand for immediate consumption, it will be
difficult to maintain. Should the sellers of tea
attempt to regulate the weekly offerings, it will
be necessary to take into account the surplus
over the quantity at the same time in last year,
which has passed into the stocks of dealers and
blenders.
Although 1909 is starting at a more moderate
level of price and with better general financial
conditions, there are some factors in the future
that may be viewed with concern. China tea
can be dismissed as a negligible quantity ; Java
may show further development ; Ceylon looks
like being stationary or even retrograde in
yield, but India is still very far from having
reached a maximum possible, without making
any allowance for newareas coming into bearing,
Given generally favourable weather conditions,
with the full labour forces now on the majority
of estates everywhere, there is the possibility
ofa large increase in production at any time,
With the home consumption practically stan-
ding still and the foreign trade taken all round
not progressive,a large yield would be disastrous.
There is hope that the lower prices may stimu-
late consumrz tion and that possibly the foreign
trade of 1909 may expand, because it would ap-
pear asif part of the large export business done
in 1907 was because of an over-estimation of
requirements, leading to a corresponding reduc-
tion in requirements during 1908.—McM&rxkin

JAPANESE CAMPHOR.
In its December issue the “Toyo Yakuho” of
Yokohama refers to the Japanese camphor-
agency recently acquired by the Mitsui Com-
pany. Owing to the fact that Japanese camphor
had to face the powerful competition of the
cheaper Chinese and synthetic camphor, the
company, it states, resolved to obtain absolute
control of the business, and to place the staple
on the foreign market in the same way as ordi-
nary merchandise, without being subject to
Government control. Last August the European
market heavily declined, and the Formosan
monopoly authorities were filled with dismay,
The Mitsui Company, quick to seize the oppor-
tunity, lost no time in persuading the authori-
ties that the present system of working the
monopoly was very inconvenient, as it impeded
the taking of prompt action to meet circumstan-
ces. By the present arrangement the Minister
of Finance agrees to relegate to the Formosan
Government the right to dictate the price of
camphor abroad, the Formosan Government in
turn being authorised to place the matter in the
hands of the London and New York agents of
the monopoly. These ofticials are thus enabled
to lower or raise the price according to their
own judgment, and they are now transactin
business on these lines in London and New
York.—Chemist and Druggist, Jan, 16, ;

SEYCHELLES CINNAMON OIL
INDUSTRY.
The possibility of the profitable establish-
ment of an essential oil industry in the Sey-
chelles Islands has long been under experimen-
tal consideration, and about two years ago the
idea was first put into operation on a commercial
scale, when a modern factory, provided with a
boiler and a still of 4,000 litres capacity, was
erected. In 1906 work was started by the dis-
tillation of citronella and lemon grass; but owing
to the late fall in price of the oils obtained from
these twce grasses, 16 was decided in 1907 to make
cinnamon oil the chief product of the factory for
the present. The cinnamon grown in the Sey-
chelles is the same variety as that cultivated in
Ceylon. Oilis yielded by the roots, the bark,
and the leaves of this plant, but from the bark
is the most valuable of the three products. The
trees are cut down periodically, and the bark
from which the oil is distilled is obtained from
the young shoots arising from the stumps.
These shoots are available for the purpose in
about two years. It is not only the young shoots,
however, from which the bark is obtained
yielding the cinnamon oil. This is contained
in the same proportion by the bark from older
trees, and tall trees about 1 ft. in diameter are
said to yield as much as 100lb. of dry bark when
cut down. the average tree, however, coes not
give more than about 20lb. of dry bark. This
contains from 9 to 94 per cent of cinnamon oil.
Samples of oil produced in the Seychelles by
water distillation about two years ago were
forwarded to Europe and valued at about £2 63
er litre (2 litre being approximately 1 pint.)
t is anticipated, however, that with the im-
provements in the product brought about as the
result of the establishment of the new factory,
a higher price will be obtained in future and
the industry placed upon a sure footing.—

FRENCH SYNTHETIC CAMPHOR.
An Extraordinary Flotation !
ARTIFICIAL CAMPHOR,—It is reported from France that
a new company, known as the Société le Camphre, of 65,
Boulevard de Strasbourg, Paris, is to acquire various patents
for the production of synthetic camphor, including those of
MM. Dubose and Behal. A factory has been secured at
Bonniéres, and work isto be ‘‘ commenced in the course of
afew months.” The old story is circulated that the plan
will be capable of producing three to six tons of artificial
camphor per day !|—C. & D., Aug. 31, 1907. :
Since the above paragraph was. written,
facts have transpired which show that the
Société le Camphre has fallen upon evil times,
the company having practically exhausted its
capital of 7,100,000f. (284,0C0/.), while the pro-
duction has been relatively unimportant. This
much we gather from lengthy reports on the
condition of the company which have been pub-
lished in the French financial Press. Although
the company was formed in February 1907, no
rofit-and-loss account has been issued, but a
statement of accounts to June 30, 1908, shows
that a sum of 4,169,732f. has been expended on
the purchase of patents, and that a further
2,300,9C0f, has been laid out in land, buildings,
etc. On June 30, 1908, there was 521,070f. at
the disposal of the company, while the Nabilities

were 270,497f., leaving a balance of 250,573f.,
which was insuflicient to meet working-expenses,
so that a fresh issue of capital is necessary. It
appears that ‘Loe Camphre’ was an afiiliated
undertaking of the Société!’ Oyonnithe, which
had been able to secure the patents for the manu-
facture of synthetic camphor, and they in turn
formed or caused to be formed another company
to which they sold the patents. Subsequently
the shares were ‘boomed,’ and the interest of the
public was excited to such an extent that many
shares were disposed of by the promoters at
more than 100 per cent premium. It is not known
what proportion of these gains accrued to
‘?Oyonnithe,’ but on December 31, 1907, this
company did not possess a single share of the
affiliated company, showing that'the confidence
inspired in the new company was not very great.
Time has proved the wisdom of ‘ l’Oyonnithe,’
as the 100f. shares of ‘Le Camphre’ are now
worth 36f. only. The meeting of shareholders
on December 31 was stormy, considering that
many of them had purchased shares at double
the par value. The present board of directors
were only able to hold on to their office by the
votes of absent shareholders. Aggrieved share-
holders pointed out that the company had been
stating that the daily production of synthetic
camphor was 200 kilos., whereas it appears the
company has only produced 2,500 kilos. since
its formation. Professor Behal declares he has
not received a penny for the sale of his patents,
though he was also promised a bonus of 25c.
per kilo. on the manufacture.—Chemist & Drug-
gist, Jan. 16.

great prospects. Germany already consumes

ments offered here have been up to the present
still unimportant. London offers, however, al-
ways lower than Ceylon itself. The import of

mended. From Borneo arrived shipments of fair

PRODUCTION OF HERVA MATE
IN’ BRAZIL.
‘* PARAGUAYAN TEA.”
H.M. Legation in Brazil has forwarded the
following memorandum on the production of
herva maté in Brazil. It appears that this
article took the third place in Brazilian exports
in 1906, and fifth place in 1907, the value of
the export each year being nearly 2,000,002. :—
‘‘*Tlex Paraguayersis’ or Paraguayan tea,
known also as ‘ Missionaries’ tea’ and ‘ Jesuits’
tea,’ is to be found wild in immense quantities
in the Brazilian States of Rio Grande do Sul,
Santa Catharina, Paranda, Matto Grosso, Sio
Faulo, Goyaz and Minas Geraes; but more
particularly in Parana. It was first discovered
by the early missionaries, who found it in use
among thenatives of Paraguay, to which country
it is also indigenous, It is met with generally
in the form ofa tree ransing from 9 to 18 feet
in height, there being three varieties of the
species known, viz., the ‘latifolia’ with broad
leaves, the ‘longifolia’ with long leaves, aud the
‘aneustifolia’ with small leaves, tho last of
these being the most appreciated.
METHOD oF HARVESTING.
It is gathered between the months of April
and September, the leaves being considered
more mature for the purpose in June and
August, and the trees are allowed from four to
five years to recover from the effects of a very
rough harvest. The branches are broken off
and the leaves are withered over a smokeless
bonfire, to prevent them from turuing black, and
they are further submitted to a primitive pro-
cess of ‘curing’ later.
MAKING THE Brew.
“The original method of consuming maté,
and the manner still in vogue in South American
countries, is to pour hot water on the top. of
the leaves and sip through a tube—the same
leaves serving for innumerable brews if they
are not allowed to cool. Itis found, however,
to give a very good result when prepared like
other teas, and, in comparison with the latter,
is said to be much more digestible and less
harmful to the nerves. It is further stated
by writers on the subject to be a stimulant and
tonic, its qualities in these respects having been
very marked indeed during the Paraguayan
war, at which time soldiers wers found to be
able to endure the greatest hardships and go
for days without food if provided with mate,
“The French Consular Agent in Curityba, some
time back, tried to bring herva maté before the
notice of his Government. for tiv use of the
French colonial army, he being persuaded that
it would prove a preventative against abuse of
alcohol and tropical diseases. To support his
arguments he stated that a German military-
medical council had recommended its substitu-
tion for ordinary tea generally among the
German troops. This may account for the fact
that maté is beginning to find its way now into
Germany, and even more go into Italy, though
the imports into both these countries at present
4
are very insignificant. [t is also becoming
known in france and Portugal, whilst the
amount sent to England has so far scarcely
attained the proportions of a sample.
Tue NAaTuRAL SuPPLY
of the Southern Brazilian forests is reputed to
be inexhaustible, and presumably could at any
time be largely increased by planting and culti-
vation if there were greater demands for it. In
the meantime the exports are considerable to
Argentina, Uruguay and Chile, with occasional
shipments to Paraguay also, though none what-
ever is exported to any of the other countries
in South America.
‘‘Maté of course is considerably cheaper in this
part of the world than are eastern teas, and
those by whom the taste for it has already been
acquired are loud in declaring it to be whole-
some and refreshing and to be possessed of
innumerable medicinal virtues. The maté
which is shipped from Rio de Janeiro and the
other important ports of Brazilis usually ‘in
transit,’ the natural ports for direct shipments
being the little-known places, such as Paranagua,
Antouina, Sao Francisco, Porto Murtinho and
Porto Alegre. The increase in the export from
Porto Alegre in the last few years has been very
remarkable. Inthe year 1902 only 11 tons were
shipped, while in 1906 the shipments had in-
creased to 11,000 tons, an advance which, while
enormous, has at the same time been gradual
and has since been maintained,

SHAPING YOUNG PARA RUBBER

Mr Walter Towgood writes as follows :—It is
still an open question whether it is advisable to
interfere with nature by forcing young rubber
trees to throw out branches. Almost all culti-
vated trees are pruned and shaped according to
the requirements of the agriculturist and in
some cases a tree’s natural habit is entirely
altered, as for instance, in tea and coffee, The
former of these is, however grown for its leaf
and the latter for its fruit, but in Para rubber
we have to deal with the products of the bark
and therefore the shaping of the stems.
Hitherto attempts have been made to force
rubber trees to branch by thumbnail pruning or
topping, but this has not been attended with
success, as the upward growth of the tree being
stopped, the place of the main stem is taken
not by true branches, but by suckers which are
very liable to split off and in dcing so the stem
itself is also frequently split, thereby seriously
damaging the tree. Moreover, the tree once
having been headed back, the tapping height of
288
the stem is fixed forall time. T have recantly
found that rubber trees can be forced to throw
out true branches without interfering with
their upward growth. It is then only necessary
to prune off superfluous branches in order to
shape the tree in any desired form; to accomplish
this all that is necessary is to cut off all the
leaves, leaving the stalks attached to the stem,
these will dry and fall off ina few days and
the treo will throw out branches from each node.
Para rubber being a deciduous tree, this re-
moval of the leaves is, after all, merely a fore-
stalment of nature and should therefore be done
at the season when the older trees shed their
leaves. It is also best to choose the time when
the topmost shoot has matured and before a
fresh shoot has commenced to grow. Great care
must be taken not to injure the bud and thereby
interfere with the upward growth of the tree.
The above method should only be tried on a
very smal! scale to begin with, until it has been
proved a success.— Malay Mail, Jan. 25.
RUBBER IN BOLIVIA.
The following extracts from a Broker’s Cir-
cular, (December 30th) give some interesting
information in reference to rubber yield, &c.,
in Bolivia :-—
“Tae GALVEZ Rupper Estates, Ltp.”
This Company was registered in 1907, whena
prospectus was issued for private subscription
only. Capital £150,000 of which £135,000 has
been issued in £1 shares all fully paid. The
largest. shareholders are Sir George Newnes,
Bart., M.P., his family and friends, The Chair-
man of the Company is Mr. Frank Newnes,
M.P., and the Harmsworth family also of news-
paper fame are also interested. We extract the
following from the prospectus :—
‘¢ This Company has been formed in order to
acquire the Galvez Rubber Estates, a well-
known fine Para rubber-producing property in
Bolivia, and consisting of the properties here-
after mentioned. It is estimated to extend
over an area of nearly million acres, and is
situated in the province of Canpolican, district
of La Paz, near the Beni River, Bolivia.
“Mr Pharaoh, who is well known in America
as an expert in Rubber Forests, and who has
worked a portion of the concessions, has certi-
fied toat least 300,000 trees (Hevea brasiliensis),
Taking a minimum yield of only 4 lb. per tree,
this would give areturn of 1,200,000 lb. rubber
per annum. Mr Pharaoh states that 6 lb. per
tree is a conservative estimate. 150,000 trees
opened up and ready for tapping should pro-
duce 600,000 Ib. of rubber, which at say 5s. the
present price, would realise £150,000 per annum
gross. ‘The business has been a going con-
cern for the rast six years. The recent
owner, Senor Mariano Galvez, of Arequipa,
Peru, through lack of capital, has for some
years past confined himself to the development
The Supplement to the Tropical Agriculturist
of only a small part of the estate, which he
states has yielded rubber yearly valued at from
£20,000 to £30,000 gross. The output for 1905, em-
ploying only 100 pickers, amounted to 79,000 Ib.
and for a few months in 1906, employing 200
men, 66,000 1b. Inthe year 1902, Mr Pharaoh
worked the property during a period of eight
months. He had only 200 pickers, and they
collected 120,000 lb of rubber from only a small
portion of the property, and which atthe pre-
sent price of rubber would sell for £30,000,
‘ Kstimating the all-round sale price of rub-
ber at 5s per |b and the cost of production at
2s per lb, the total yield of 300,000 trees at 4 lb,
per tree would equal 1,200,000 1b and would pro-
duce a profit of about £180,000 per annum.
‘Taking asa basis the production available
from only 15°,000 trees, this would give the
fullowing results :~
600,000 1b. rubber at 5s. perlb £150,000
600,000 re at cost of

Leaving an estimated nett pro-
fit per annum of £90,000
‘‘ Last year, subsequent to the formation of
the Company, as you will remember, there was
a financial panic in the United States of America,
which are the largest buyers in the world of
rubber. As the result of this the enormous
factories there were closed, and the price of
rubber fell from over 8s to 3s perlb. With
a resumption in the United States of the
demand, the price has gradually risen until
now it 1s again over 5s, with every prospect of
a continuance of at least this price. The es-
timate given ot production naturally does not
apply to the first year, during which the busi-
ness had to be thoroughly organised. Ship-
ments of rubber up to date have been 300,00,
lb. and further 600,000 Ib. has been collected
and will be gradually shipped.”
This Company probably owns the largest quan-
tity of indigenous rubber trees of any English
Company. We wish distinctly to emphasise
the fact that the total production of rubber per
annum is about 70,000 tons. Of this quantity
only a little over 2,000 tons is produced from
plantation rubber trees in the East, The entire
balance is obtained from indigenous rubber
trees. We further wish particularly to empha-
siseo the fact that the production of rubber per
tree from planted trees in the East is only about
1 lb, as against 4 1b. from the indigenous trecs
in South America.
An interim dividend of 3 per cent was paid in
July. It is expected the first report and balance
sheet will shortly be issued, aad that the divi-
dend will amount to at least 10 per cent. This,
it is expected, will be more than doubled next
year, and continue to largely increase from year
to year ; in fact, from the official figures already
given it appears the Company should have no
difficulty in paying 80 per cent dividend next
year. [Shares are offering at par.]

BURYING /S BURNING OF TEA
PRUNINGS.
THeir Errect as Manure In Cryton.
Before the Neboda Tea Co. of Ceylon on
Feb. 13th., Mr. Joseph Fraser made a most im-
portant statement on the question of burying
vs burning of tea prunings, which is given
below. ith prunings buried (with basic
slag, &c.) one division showed as large a yield
as 1,179 lb. per acre. Another estate visi-
ted by Mr. Fraser is quoted in support of
“burying ”: on this there was a definite experi-
went. Before treatment the yield per acre on
one field was 300 lb. and after four years 920 lb,
—while on an artificially manured field ad-
joining it had increased to 690 lb. only. Simi-
larly upcountry, burying prunings with bulk artifi-
cial manure and albizzia leaves and twigs brought
the yields up to an average of nearly 1,100 |b,
with a maximum of 1,481 1b. per acre! The
figures as to cost we commend to the attention
of planters. As to whether Mr. John Hughes
‘‘oof mixed” in his references to manuring and
burying, we may leave him to deal with more
elaborately than we could; but Mr. Fraser,
it should be pointed out, gives the most valu-
able analytical figures, for the chemical and
cultural results achieved, and emphasizes the
cumulative effects of burying, with a proviso
against its employment in root pest centres,
stiff soil or bleak situations. Practical and
scientific planters will be grateful for the full
statement he presented at the Neboda meeting.
MR. FRASERS’ STATEMENT.
At the Annual Meeting of shareholders of the
Neboda Tea Co. of Ceylon. Ltd. The CHAIRMAN
(Mr. Joseph Fraser)—in moving the adoption of
the report—said :—The results of the year’s
working may be considered highly satisfactory.
The average tea yield was 803 1b. per acre in-
cluding 27 acres of Tea and Rubber. Allow-
ing for manuring items, and loss on rice, the
nett cost was a shade under 19 cents per lb.
and the profit exclusive of loss on rice, which
I trust is more or less a temporary item, R89°69
per acre or say £6 sterling. Narthupana divi-
sion that has had the
PRUNING SYSTEMATICALLY BURIED,
with the Basic Slag and Sulphate of potash,
plus artificial manure, gave from the whole 227
acres an average yield of 960 1b, per acre,
the best yield being 1,179 Ib. A thoroughly
cultivated field on the Neboda division 33 acres
gave 987 lb. per acre, but 110 acres that were
cultivated only occasionally, the labour not
being available, owing to rubber extensions,
gave an average of 687 lb. per acre, while two
fields of 57 acres, never manured or cultivated,
only yielded 309 lb. per acre. They were,
however, pruned within the year, but the aver-
age for two years was under 400 lb. and that
too from fine indigenous tea. Tho results
therefore of burying prunings, plus manuring,
in this instance, seem fully justified,
37
289
A DEFINITE EXPERIMENT
in two adjoining fields, on an estate I visit,
further confirms this. They have the same
aspect, lay of land, and soil, and were yield-
ing an average in the pruned, and unpruned
years, before they were manured, or cultivated,
of under 300 lb. per acre, per annum. One
field had the prunings buried with Basic
Slag and Sulphate of potash and six months
afterwards was manured with artificial. The
other field was manured with a similar mix-
ture of artificial only, at a corresponding
period from pruning, and in both instances,
this has been repeated four times or for eight
years, the fields being pruned every two years.
The first two years the advantage of burying
prunings was small, and showed a loss, if
charged with the Basic Slag and Sulphate of
potash, the second covered cost, and the third
showed a profit, that is compared to the field
treated with artificial manure only. The fourth,
however, was highly satisfactory. The average
yield from the field manured with artificial for
the two years,
ending 31st December, 1908 was 690 lb. per acre
and from the buried prunings
and manured field ... 920

As regards the size of the bushes, the class
of pruning wood,their healthy, vigorous look and
freedom from pests, the advantage all along was
clearly in favour of the buried prunings and
manured field. On another group at from 2,600
feet to 4,600 feet above sea level the following
results have been secured by burying prunings
with bulk and Albizzia leaves and twigs and artifi-
cial, in three fields aggregating 94 acres, 1,064,
1,057 and 1,165 lb. per acre per annum for the
past three years, the highest yield in any one
year being 1,481 lb, per acre—results are not
generally so apparent, particularly in poor old
coffee land soils, with miserably stunted bushes,
but the indirect advantages in developing heal-
thy ones with good pruning wood can seldom be
questioned. The actual cost of burying prunings,
in cooly labour, is from say R4 per acre for
small bushes up to R10 to R12 per acre even
for very large ones, but in that case the bushes
run from 30 to 36 months from prunings. Allow-
ing the yield to vary from 400 lb. to 1,200 Ib.
per acre per annum, the cost would work out for
a 2-yearly pruning at 4 cent per lb. and less
when the 3-yearly system is adopted. Mr John
Alughes evidently got sadly mixed in regard to
this, and appears to have included, all the
manuring items under burying prunings.
The following figures are interesting in this
connection ;—=

oped bushes per acre per

The above would indicate that the burying of
prunings is clearly cumulative in its effects and
may saiely be carried out except in cold bleak
situations and in stiff soil, or where Rosellinia
or other allied root pests are distinctly trouble-
some. The total cultivated area is 1,121 acres or
R303 per acre on the paid up capital of the Com-
pany say £20 4s Od sterling—the 694 acres of
Rubber including the cost of land stands us on
31st December 1908 in R221°51 per acre with 120
acres now in bearing. The Rubber crop for
1908 was 8,683 lb. and realised R3‘06 per Ib.
nett which may be considered satistactory
as prices were poor in the early part of this
season. The estimate for 1909 is 20,000 lb.
The cost of upkeep of the Rubber clearings is
now very small, weeding varying from 30 cents
per acre per month to Rl per acre that being
the highest rate we are now paying. Mr.
Callander is to be congratulated on his thorough
work in this respect, he being fully alive to
the necessity of removing all weeds before
they seed, the only method whereby cheap and
efficient work can be secured, Real clean
weeding, means as a rule, labour well under
control, with the iull advantage that it can be
efficiently adjusted, to requirements without
waste. A contract for a Rubber Factory has
been given out, coolies are ample for require-
ments and all the coast advances are quite safe.
They stand in at R22°20 per head. With these
remarks I beg to move the adoption of the report.

THE GOVERNMENT MYCOLOGIST ADVO-
CATES BURNING OF PRUNINGS.
The question at issue is whether the burning
or burying of tea prunings is the most econo-
mical and safe method of disposing of them.
Mr. Joseph Fraser has given particulars of
a system of cultivation employed upon a
certain estate, which included the burying of
-prunings. The estate in question showed excel-
lent results from the commencement of this treat-
ment. Mr. T. Petch, the Government Mycologist
—an advocate of the burning of prunings —favours
us withthe following letter criticising Mr. Fraser’s
conclusions. Mr. Petch is not prepared to
The Supplement to the Tropical Agriculturist
admit that the results, quoted by Mr. Fraser,
are due to the systematic burying of prunings.
There is nothing to show, he argues, that
the improved yield is not due to the other com-
ponent parts of the scheme of cultivation ; or to
justify the belief that the results would not have
been the same, had the prunings not been buried.
Mr. Petch reasons ably and ingeniously froma
scientific standpoint ; but we hardly think his
arguments will convince the practical planter, who
is seeking for the best method of economically
disposing of his prunings and at the same time
getting the maximum yield from his tea. It is
demonstrated by Mr. Fraser that a system of
cultivation which includes as an essential part
the burying of prunings results in substantially
increased crops. It1s, to use an Americanism,
‘Cup to” the critics of this system to demon-
strate that equally good or better results,
can be secured by the same system minus the
burying of prunings. As matters stand, if Mr.
Fraser, as is asserted, supplies no data to shew
that the burying of prunings contributes largely
to these results, Mr. Petch equally fails to
prove that it does not. The ordinary ‘“‘ man
in the tea,” not possessed of the same deep
scientific knowledge as Mr Petch and Mr Fraser,
will be content with the knowledge that here
isa successful system of cultivation of which
burying prunings is said to be an essential part ;
he will be content to follow the system and
secure increased crops until it is demonstrated
—if it can be—that the same results can be
secured without burying the prunings. Mr
Joseph Fraser is a busy man, who has fre-
quently declared time will not permit him to
carry on newspaper controversies ; but there are
one or two points in Mr Petch’s criticism, on
which a brief statement in reply would be
welcomed and might not necessarily require to
be followed by others.
Mir. T. Petch’s Criticism of Mr. Joseph Fraser’s
‘*Neboda” Statement.
Feb. 18th.
Sir,-The figures quoted for Mahawale(see page
188 of last month’s issue of T.A.and Mag. of C.
A.S.)and other estate must be very satisfactory re-
ading for the shareholders, but they give no infor-
mation whatever on the pointatissue. And I may
forestall those who think that this may be
answered by stating that the financial side—and
not the theoretical side—is of more importance
to the employer, by pointing outthat there is
nothing to indicate that the same results would
not have been obtained if the prunings had been
omitted,
Consider the case of Mahawale: (1) Prunings
are buried and (2) the land thereby cultivated
to some extent, (3) Manure has been applied,
(4) Albizzia leaves have been buried, (5) Rubber
has been planted through the tea, And the crop
since this was begun in 1904 has been 482 ; 552;
578; 746, and 807 |b. per acre perannum. But
why select No. 1, and deduce that the burial
of prunings is beneficial? Should I not be
equally justified in assuming from the data that
interplanting with rubber is beneficial? There
are five factors, and it is impossible to separate
them, Itis magnificent, but it is not experiment,
and Magazine uf the Ceylon Agricultural Society:
Why not go back to 1902 when the yield, as
far as I can discover, was 182 lb. per acre? How
did it become 420 lb, in 1903, without manure,
or prunings, or albizzias? The increases for the
years given are 14°5, 4'7, 29, and 82 per cent. It
would be interesting to know the reason of these
periodic differences in the annual increase: is
it pure chance that the greater coincide with
the two great increases in the total Ceylon crop
since 1904? It may be pointed out, by the way,
that a difference of 8 per cent. in a field experi-
ment is regarded as inconclusive. Some fields
yielded 700 lb. per acre in 1904: have they
shared in the general increase, and do they
now yield 1,150 lb. per acre? How isit that
Mahawale shows in one year again of 14 per
cent., when ‘‘from the burying of prunings,
quick returns are not to be looked for, or ex-
pected,” and another estate, more liberally
treated, does not show a profit for four years ?
But when was Mahawale opened ? I do not
find it in the Directory for 1896-7, And were the
650 acres of tea all planted at the same time ?
Apart from the fact that itis not an experiment
in burying tea prunings, it would appear that
all the cards are not on the table in this case.
Take now the ‘‘definite experiment” on two
adjoining fields. The average crop for the two
was under 300 lb. peracre. It is unfortunate
that the yields are not given separately, because
if one gave 330 lb. and the other 270 lb., the bot-
tom is knocked clean out of the experiment. But
this does not affect the value of the experiment
from the point of view of the present discussion,
*‘A” had cultivation, buried prunings, basic slag,
sulphate of potash, and artificial manure. B had
artificial manure only ; aud the two fields were
not treated at the same time, This last may be a
minor detail: Still, it is best to avoid all pos-
sible errors in making a ‘‘ definite experiment.”
After eight years’ treatment, A shows an ad-
vantage of 33 percent. per annum over B. It
is no doubt a successful experiment in manuring
tea ; but if it was designed to show the benefit
derived from burying prunings, it was most
hopelessly misconceived. It only shows that the
treatment accorded lo A gives a better yield than
the treatment accorded to B. Butdothe culti-
vation, and the basic slag, and the sulphate of
potash count for nothing ? How much of the
gain is due to each ? To make a difference in four
factors (or five, if the time is taken into account),
and then to quote the result as a proof of the ad-
vantage of one of them, is utterly unjustifiable,
and it supports the previous contention that
what passes for experiment in tropical agri-
culture is often the most feeble imitation. Ex-
amples of such ‘‘experiments” can be quoted
by the dozen, and none of them proves any-
thing ‘‘definite.” Zo obtain any evidence on the
subject of burying prunings, B should have re-
ceived exactly the same treatment as A, minus
the prunings, at the same time, even to the ex-
tent of digging holes and filling them up again,
and there should have been a control plot.
I have been referred to theories and figures
sent some years ago to the Experiment Station
Committee. The figures there are nearly those
published in Saturday’s issue, viz., that the
prunings from @ highly-manured, well-plucked,
291
medium-pruned estate, with large well deve-
loped bushes, remove 101 |b. of nitrogen per
annum, etc. Presumably this is 202 lb. per
pruning. The figures are indisputable. I do not
mean that they are correct, but that they are
not open to discussion. We might just as well
be told the total of an obliterated column of
figures, and asked to discuss its accuracy. If
the justification of the burial of prunings
is to be based on their manurial value, the
figures must be supported by details which give
them some semblance of probability,
Some idea of the accuracy of the figures
cited above may be gathered from the fol-
lowing sentence, which is quoted from the
manuscript referred to: ‘‘It does not appear
financially sound to throw or waste tea pru-
ei containing 4 to 4% per cent. of nitrogen
in their dry substance, to be replaced by orga-
nic matter containing 2‘) to 4 percent. at most,
even though secured from the nitrogen of the
air by the aid of nodule bacteria.” It certainly
does not : but whoever claims that tea prunings
contain 4 per cent. of nitrogen in their dry
substance? We are told that the leaves (dry)
contain 44 per cent. Surely itis obvious that
the great mass of the pruningsconsists of wood
which has only a small nitrogen content. In
the absence of details we are left to guess
where the fallacies lie; but the two most pro-
bable are: (1) the nitrogen content of the leaves
is applied to the whole of the prunings, and (2)
there is a confusion of ‘twet weight” with ‘‘dry
weight.” Percentages, to be of any use, must
be calculated on the dry weight, ‘.¢., after
drying at 100° Cent. until constant.
The figures for Hevea give a typical example.
The leaves (dry) contain 3°44 per cent. of nitro-
gon; the twigs, °62 per cent. ; and the wood, °59
per cent. What are the corresponding figures
for tea?—and will the nitrogen content of the
whole of the prunings exceed 1°5 per cent? To
estimate this we must know the dry weights of
the leaves and green twigs, red wood, and old
wood removed per acre, and the nitrogen con-
tent of each. As far as regards loss of weight,
on drying, old tea leaves lose over 60 per cent.,
green shoots with full-grown leaves lose over 70
per cent., red wood loses 69 per cent, and old
loses over 50 per cent.
202 Ib. of nitrogen are said to be removed in
the prunings of oneacre. If we take the nitro-
gen percentage as 4, this requires 5,050 lb. of
ry prunings: and putting the average loss of
weight indrying at 60 per cent., this means 12,500
Ib. of prunings in their natural condition. But
this percentage of nitrogen is most probably
three times too great, and, therefore, the pru-
nings required will be about 37,500 lb per acre.
To illustrate our lack of facts,— can any planter
say, to half-a-ton, what weight of prunings is
removed per acre on his estate ?
I hope the above will give some idea of the
figures and experiments required to solve this
question. At present those who advocate the
burial of prunings because of their manurial
value, give no valid basis whatever for their
belief. We do not know how much nitrogen
or what weight of dry material is removed
292
per acre. And when the first of these points
has been settled, there still remains the ques-
tion raised in my article on Tea Root Diseases,
viz., how much of this nitrogen ever becomes
available for the plant ?

MR. JOSEPH FRASER IN REPLY TO
MR. T. PETCH.
We are obliged to Mr. Joseph Fraser for the
following letter he favours us with replying
to some of the criticisms made on _ his
Neboda statement by Mr. ‘ Petch, the
Government Mycologist, With regard to the
two fields on Neboda which yielded under
300 lb. per acre before the definite ex-
periment was made, Mr. Petch regretted that
the yields were not given separately because,
he said, if one had given 330 and the other
270 lb. the bottom was knocked clean out of
the experiment. The fields, Mr. Fraser points
out, were giving within 10 lb. of each other.
Mr. Petch questioned the statement—‘ tea
prunings containing 4 to 44 per cent. of nitro-
gen in their dry substance.” He pointed out
that prunings consisted mainly of wood which,
he said had only ‘‘a small nitrogen content ”
and he assumed that a wrong result had been
arrived at by applying the nitrogen content
of the leaves to the whole prunings and by
some confusion of ‘“ wet weight ” with.* dry.”
There were, it will be seen from Mr. Fraser’s
reply, no such errors. The percentage of nit-
rogen was calculated on the whole dry weight
of the material, Mr. Fraser quotes a very
striking instance from Mahawale. A field which
was almost abandoned, being the poorest on
the estate, after being cultivated and prunings
systematically buried, gave an average of 1,001
lb. for the last two years! Mr. Fraser gives
in anutshell the reasons for his firm belief in the
burying of prunings and he concludes, what
we venture to think will be regarded by those
interested in the subject as a most valuable
contribution to the controversy, by throwing
down the gauntlet to those who differ from
him, Recognising the shrewdness of the
average Ceylon planter, Mr. Fraser declares that
the planting community ‘‘will be only to pleased
to adopt other methods, when they have been
proved to be cheaper and more efficient in
developing healthy well-nourished bushes, with
fine pruning wood, plus a good field.” Will any
planting champion of Burning Prunings ac-
cepted the challenge ?
Mr. Fraser’s REPLY.
Kandy, Feb. 20th.
S1t,—With reference to Mr Petch’s remarks
on my Neboda statement, I seem to have not
made myself cleat as regards the yields of the
fields I used as anillustration. They gave before
the experiment was started under 8001b. per acre
per annum each, and within 10 |b. of each other.
Regarding the analysis of the prunings they
were calculated out on the dry weight of the
material, and separate analyses were made of
the leaves, and woody matter. [ supplied the
figures as regards the weight of green matter,
The Supplement to the Tropical Agriculiurist
based onaseries of weighings of the average

Colombo Commercial Co.’s Analysts supplied the
remaining data.
Referring to Mahawale, I may mention that
what was originally the poorest field on the
estate and, at one time, was all but abandoned,
gave an average for the last two years of 1,001 lb.
per acre per annum; and this I largely attribute
to the burying of prunings, as in this instance,
it was consistently carried out, whereas,in fields
not so systematically treated and that were
much better to start with,the yield had consider-
ably fallen behind:
My reason for believing in the burying of
prunings is that I find when decay is more or
less complete, the tea roots freely develop in this
matrix and feed on its substances ; that the ana-
lyses of these areas are richerin nitrogen than
the surrounding ones. We also get rid of « great
many topical pests, and that over large areas
the danger from root disease is small. I feel
sure, however, that the planting community
generally will be only too pleased to adopt
other methods, when they have been proved to
be cheaper and more efficient in developing
healthy, well-nourished bushes, with fine pru-
ning wood, plus a good yield.—Yours faithfully,
JOSEPH FRASER.
ANOTHER CEYLON V.A.’S OPINION.
A very weighty letter appears hereafter from
Mr.Wm. Forsythe, strongly supporting the manu-
ring policy recommended by Mr. Joseph Fraser
which includes the burying of prunings.
We attach considerable importance to Mr.
Forsythe’s evidence. He is acknowledged a
first-class practical planter, and is one of
Ceylon’s best-known V. A.’s, whose judgment
invariably commaads respect among his fellow-
planters. He has had long experience of the
burying of prunings and the support which he
gives to Mr. Fraser’s system is based entirely on
his own practical experience of its advantages.
Few tea planters, if any, know Low Country
conditions better than our correspondent.
Mr.M L Wilkins, one of the younger school of
prominent and successful scientific planters,
also indirectly supports the burying of pru-
nings. Mr. Wilkins wants to know if Mr. Petch’s
letters are private or official. We should say
ofticial ; Mr. Petch is merely defending the posi-
tion he took up in his able paper which ap-
peared in the 7ropical Agricuiturist. Mr, Petch
is arguing from the point of view of the Myco-
logist, and in a matter of this kind it is per-
haps fairer to regard his opinions as the result
of strong convictions, rather than prejudice—
as hinted by our correspondent. Further, this
is not by any means the first time that
Doctors have disagreed, and the planters
ought to carefully study for themselves what
treatment should best suit their case. We think,
too, that even during the present discussion it
has been indisputably demonstrated that situa-
tions are conceivable where the burying of pru-
nings would not be recommended even by Mr.
Fraser as bejng attended by the possible risky
and Magazine of the Ceylon Agricultural Society.
Raed out by Mr Petch. In the lowcountry,
owever, where decay is more rapid, we think
the balance of opinion is beyond all doubt
in favour of the beneficial results of burying
prunings. We should very much like it, on the
principle of Aud) Alteram Partem, if any
planter, should such exist, who has been less
fortunate in his experience of burying prunings
than those planters whose views have already
appeared, would come forward now and state
their views.
THE BURIAL OF PRUNINGS.—I.
Feb. 25th.
Srr,—It occurs to me to enquire whether Mr.
Petch’s letters on this subject are private or
official ? [f the former, I suppose, like the rest
of us, he is entitled to his likes and dislikes ;
but if his communications are official, do you
not think that they would have much more
weight and authority if there was less flavour
of prejudice, and a greater disposition to deal
with both sides of the question ?
We have heard all about the possible dis-
advantages, minimum of nitrogen in prunings,
etc., etc., but will Mr. Petch dace that there
are any possible advantages in the burying of
prunings? What about: (1) Humus or organic
matter, (2) Potash, (3) Eradication of pests,
(4) Improvement of the mechanical condition
of the soil, etc ?
We have been told about: (1) in connection
with green manures by Mr. Petch’s colleagues,
and re (3) I think Mr. Green advocated burying
in one of his recent circulars on shot-hole-borer?
If our experts are going to contradict each
other, what are we to believe? Many of our
leading practical and successful planters seem to
be of the opinion that, amongst other advantages
the burial of prunings with slag, etc., improves
both the bush and the quality of its produce.
If there is anything in this opinion, and if Mr.
Petch’s views influence us against it, it stands
to reason that such views are hardly in the best
interests of the industry as a whole.—I am, Sir,
M. L. WILKINS.
II.
Ireby, Norwood, Feb. 25th.
Sir,—I have read with the deepest interest
Mr. Petch’s letter with reference to the burying
of tea prunings and Mr. Fraser’s in reply. I
have carried out this so-called Fraser system for
many years upon low-country tea estates and
with the greatest possible benefit to the bushes
which, in every case, have improved in stamina,
and yield in a way I could never have believed.
The properties, which I have had the good for-
tune to control and work for many years, speak
for themselves. I remember them when they
were run down and I[ know them as they are now.
A continuity of artificial manuring and nothing
- else eventually proved ineffective in keeping up
the bushes and the yield ; and I was driven to
work in organic matter into the land, with the
results so clearly described by Mr. Fraser. I
_ geally cannot say what would have happened—
293
1, If I had simply cut holes for burying
prunings, and filled them in again—minus the
prunings.
If I had buried prunings only without
slag or potash.
3. If 1 had applied slag and potash to the
land without cutting holes or burying prunings.
But I do know that if I had done nething at
all, but applied artificial manure, I could not
have maintained in the low-country the vigour
of the bushes and the yield, and I say this
because I tried and [ failed many yearsago. This
is not a scientific letter, but is written to give
my practical working experience of cultivating
low-ccuntry tea for, I should say, 10 to 15 years.
7)
“se
I venture, however, to re-echo Mr. Fraser’s
pious hope; and to state that if anybody will
come along and show me how I can achieve the
same or better results in a cheaper and more
effective manner, I will throw Mr. Fraser and
all his works to the winds! Until that day
comes, I am satisfied to continue working upon
the lines which years of experience have proved
to me are, so far as our present knowledge goes,
indisputably the best.—Yours faithfully,
W. FORSYTHE.
III,
Feb, 20th,
Dear Sir,—e Mr. Petch on the Burying
of Prunings :—*t At present those who advocate
the burial of prunings, because of the manu-
rial value, give no valid basis whatever for their
belief.” I venture to refer to pages 108 and 109
in Carpenter’s Vegetable Physiology, edited by
Edwin Lankester. From page 108 I take the
following :—‘‘ Nothing more, says a vine-grower
on the banks of the Rhine, is necessary for the
raanure of a vineyard than the branches which
are cut from the vines themselves (printed in
italics),
The other day I heard on excellent authority
that the late Mr. Wall frequently used your
correspondence column to advocate that the
vineyard system of burying prunings was a
type of cultivation eminently suited for the
Ceylon tea field.—I am, Sir, &c.,
A. G. C,
LV.
Lindula, Feb, 26th,
Deak Six,—I would appear to be in good
company as to burying of prunings with Messrs,
Hughes and Petch. That correspondent, who
writes to the press re vines and this style of
cultivation, has forgotten the fesult, “ Phyl-
loxera.” Holes have to be cut tocarry tea
prunings and they become rain catchers and
hence the beneficial results. Up here I can
prove itto the hilt by ocular demonstration,
where nothing but holing has been resorted to
and all prunings left on the surface. I have no
doubt white-ants in the lowcountry eat them up
at once. In these districts we have no such
insects. Yours, &.,
E, R. WIGGIN,
294
[Mr E R Wiggin isa valiamt opponent of the
burying of prunings; but somehow he never
seems to carry us much further towards definite
information on the subject. No one will dispute
that the mere cutting of holes—involving the
aération of the soil—is attended by a certain
amount of benefit ; but if our correspondent
means to suggest that the improved yields in
the fields mentioned by Mr Joseph Fraser is
simply due to the cutting of “rain catchers”!—
we would be inclined to leave the suggestion
to be laughed out of court by all practical
planters. Mr Wiggin renounces all claim to be
taken seriously when he tries to account for
the rapid decay of the prunings in the low
country by stating that they are eaten up by
white ants !—Ep., C.0.]
THE BURIAL OF TEA PRUNINGS.
Three further letters on this important contro-
versy appear hereafter. Mr E R Wiggin quotes
the authority of Dr. Mann to support the case
against burying ; but it is a qualified opinion.
Dr. Mann recommends the burning of prun-
ings it blights or pests are prevalent in the
estate. We may state his opinion :—
“To leave prunings lying about in a garden
with these blights on them is suicidal, and to
bury them is dangerous. Ifthe garden is, how-
ever, free from Bight, there does not seem any
absolute reason against burying the light
prunings—and these only—provided the follow-
ing conditions are adhered to :—
**(1) They must be buried deep. At least 6 in.
of soil should be left on top of them, so that
they will not be turned up by the hoe.
‘*(2) They should be buried immediately on
pruning, or as soon after as possible. In
Ceylon, trenches are dug to receive the prunings
before the bushes are touched at all, and the
prunings are put into them practically at once.
Once dried up, much of the manurial value has
gone or is rendered less valuable.
‘*(3) They should be buried with something
which will destroy any latent germs or spores ot
fungi which are upon them, The best materials
for this are lime and basic slag, which not only
cause the blight spores to be destroyed but
also the prunings to rot more quickly.”
But what says Mr Claud Bald in his
‘Indian Tea: its Culture and Manufacture ” ?
He believes in burying prunings, ‘‘ which are
of great value as a manure, especially if buried
deeply and in a green state.”” He says :—
*‘Valuable manurial properties have been
destroyed by burning the prunings, while, as
compared with other gardens where the
prunings have not been burnt, there has been
no apparent result in the direction of sub-
duing the pests. Theoretically the ashes are
distributed to form manure for the whole
ground ; in most instances, however, this is
mere theory, as the ashes of an acre of prunings
are usually distributed over put a few square
ards of land.”
With regard to Mr Wiggin’s experience we note
uoted in a pamphlet entitled “ The Fertilisation
of Tea” by George A Cowie, M.A.,B.Sc. which
reached us some days ago, theopinionof Mr W B
jackson, for many years manager of the Haute-
ville Group of Estates, He commenced burying
The Supplement to the Tropical Agriculturist
prunings in 1894 and the estate has continued
doing so since, burying alternately with lime and
basic slag. ‘‘ I know of no bad results,” says Mr
Jackson, ‘‘from this practice ; but of many good
results ; and we are now as much in favour of
this plan as ever we were.” This opinion must,
of course, have been given some time ago; but it
is important as showing that even upcountry,
with the exercise of judgment, prunings may be
advantageously buried. Mr James M B Duncan
writes an interesting and fair letter on the ques-
tion. He approaches the subject in the same
spirit as ourselves, viz., with an open mind and an
anxiety to learn allthere is to be known pro and
con. Lastly we have an important letter from Mr
Petch himself, . Mr Petch quotes figures to sup-
port his contention that the amount of nitrogen
In prunings is less than 4 to 4% per cent. as
stated by Mr Joseph Fraser. We can find no
independent authority on this point at present
but Mr Bald refers to prunings ‘‘as a manure
of great value.” Mr Petch points out that he
has at present 109 estates on the root disease
list. It would be interesting to know how many
of these owe or attribute the disease to the
burying of prunings. Mr Petch also repudiates
the suggestion of prejudice. He is dealing with
the matter from the standpoint of the Mycolo-
gist and puts evidence forward that gives some
ground at any rate for his expressed fears. As
the evidence in the case stands at present,
however, we are inclined to think the practi-
cal tea planter will be more attracted to the
burying of prunings by the glamour of its good
results than repelled by the terrors of possible’
root diseases.
Ts
Lindula, March 2nd.
Sir,—I omitted to give the late Dr. Watt,
the expert of the Indian Government for tea.
He absolutely condemns the burying of prunings.
Let those laugh that win. I am content to rest
on my experience and results. The estate, I am
today writing from, has been systematically
rain-holed without that other cultivation and
the crop for 1908 was 578 lb. per acre in a ring
fence of made tea, : no mean result in a short
season.— Yours, &c.,
E. R. WIGGIN.

Doragalla Group, Pussellawa, March 1st.
Dear Sir,—This subject having considerably
interested me for some years past—to the
extent of my making various little practical
experiments on my own beside doing a good deal
of burying prunings in the regular way during
the past nine years--I have read the recent letters
by Mr Petch and others with very much interest.
The pith of Mr Petch’s letter appears to me to
be contained in this quotation from it: ‘‘There
is nothing to indicate that the same results
would not have been obtained if the prunings
had been omitted.” I have this morning re-
turned from the examination of holes in a field
where prunings were buried with basic slag and
sulphate of potash a year ago last December.
The holesin all cases show arich-looking dark
mould, full of rootlets, etc., while the woody
portions of the prunings have rotted away,
and Magazine of the Ceylon Agricultural Society.
This appearance is precisely similar to that pre-
sented by other holes dug up by me upon former
occasions. [ want to state Mr Petch’s conditions
fairly as well as I understand them, viz :—If
I had cut the same holes, mixed with the earth
taken out the same quantity, say, about 5 oz.
of basic slag and sulphate of potash and
refilled into the holes again, omitting
the prunings—will anyone contend for
one moment that these holes would now
present the same dark-coloured rich manurial-
looking appearance, full of rootlets ?—in which
the rootlets of vegetation seem simply to luxu-
riate, fourteen months after this small
quantity of, say, 1} oz. of basic slag and _ sul-
phate of potash per tea tree was applied, had
the prunings been omitted? And as_ to
how the field is doing: In appearance
it is grandly healthy. It has just given 106
pounds of made tea per acre for this last short
month of February. But here I will be fair and
hasten to state that the field was manured
last October in alternate lines, viz., those in
which the prunings had not been buried and
the fine yield is no doubt largely due tv the
manure put in. The field has given to date
5201b. for 8 months with the best months to run,
our year ending 30th June, by which time I
expect it will have given 800 to 900 Ib. tea.
The elevation of these estates would run from
about 3,500 up to near 5,000 and this particular
field would be, I should say, about 4,000 feot.
The field has heen worked up from an average
yield of 4301b. for seasons 1898-9, 1899-1900.
Although giving these additional particulars in
order tobe quite fair, let us narrow the issue
down to—as Mr Petch pithily puts it—as to
whether ‘‘the same results would not have
been obtained if the prunings had been omitted.”
My belief, or, say, my expectation, is that the
rich fertile appearance of the dug-up holes, full
of rootlets, would not be now apparent had only,
say, 5 oz of basic slag and sulphate of
potash per hole to every four trees been
applied 14 months ago, all other conditions
being equal excepting onlu the omission of
the prunings. Of course, it is admitted that
burying prunings would nof suit every soil and
all conditions without exception. Commenting
on manuring vineyards with vine branches
another correspondent suggests the result
“Phylloxera,” but as you practically say in
yourcomment he does not definitely connect
the effect he gives with the cause he assigns.
We know how very non-moral nature is: how
human cannibals have been found physically and
generally fitter than neighbouring non-canribals,
and how much cannibalism there is throughout
nature; so that the objections to burying pru-
nings must be looked for vutside that idea, I
rayself can supply one great objection if labour
is short, viz., that the work is expensive in cooly
labour and this objection appeals very forcibly
to the man who has to get everything done and
wants to apply his labour elsewhere. In the
meantime my own attitude of mind is an open
one anxious to learn all I can upon the subject
of cultivation in its various branches. Thanking
Messrs, Petch, Fraser and others for their letters
on the subject, —Iam, dear Sir, yours faithfully,
JAS, M, B. DUNCAN,

III.
Mr. Petch Explains His Position.
March Ist.
Six,—Mr, Cochran's figures support my state-
ment that tea prunings do not contain 4 per
cent of nitrogen. He analysed the prunings of
10 bushes, from Madulkele estate, They were
divided into two lots,—leaves, seeds and twigs
weighing (dry) 56°67 ounces, and twigs and
branches weighing (dry) 46°257 ounces. The
first gave 2°794 per cent.,and the second 1°26 per
cent. of nitrogen. The total dry weight was
102°927 ounces, containing 2-1 per cent. of
nitrogen. Taking 3,110 bushes to the acre (Mr.
Cochran’s estimate) the prunings remove 42 lb.
of nitrogen per acre, or, on a two-yearly pru-
ning, 21 lb. per annum. The total dry weight of
the prunings is 2,000 Ib, per acre, or, assuming
as before that they lose 60 per cent. on drying,
5,000 lb. of green prunings peracre. If the
pruning is heavier, more wood is removed, and
the percentage of nitrogen is diminished.
There is a misconception current with regard
to the relation of tea roots to the holesin which
prunings are buried. The direction andamount
of growth of roots is governed chiefly by the
water supply, and the roots “seek” the pru-
ning holes because the soil there is moister. The
material for the formation of these roots comes
from the bush.
May I trespass further on your space to re-
state my position? As the burying of prunings
of any cultivation, among the trees or bushes
from which they are taken, is a most extraordi-
nary proceeding from a mycological standpoint,
I raised the question in an article on Tea Root
Diseases in 19V6._ 't must have been discussed
without ‘‘ prejudice,” because it has since been
quoted in favour of both burying and burning!
I was told that the whole question had been
worked out long ago, and all details were known.
But I could not get at them, at least at anything
definite. Recently [ have had occasion to in-
vestigate a new tea root disease, as far as time
permitted, and I took advantage of the first op-
portunity to re-open the subject. This time
we have been put in possession of the facts
relied on by the ‘‘other side”; and I have
ventured to criticise them, I think I have
shown that the amount of nitrogen in the
prunings is not the 4 percent. claimed, and
that the experiments are not such as would
carry conviction at, say, Rothamstead, or
Woburn, or Wisley. ;
Of course, the whole question is a matter
of balancing losses and gains: and te me the
gains appear to have been over-estimated. But
Il have no prejudice in the matter, beyond
a prejudice against unnecessary, 7. ¢., avoid-
able, diseases. Root diseases of tea were first
brought to notice in 1901, and I have now
109 tea estates on the root disease list. That
is, 109 estates have sent in specimens for re-
port. Others have been seen when on tour,
and many estates do not bring their diseases
to Peradeniya.
The advantages of burying prunings are :—
(1) A gain in humus,
(2) A certain amount of cultivation,
(3) A gain in manures,
296
I consider that too much has been made of
the third point ; that most of the advantage is
due to the second; and that this can be obtained
by less dangerous methods. Destruction of
pests by burying seems to me very doubtful,
unless they are caterpillars and get squashed.
Certainly no fungus is killed by burying it.
As regards the disadvantages, the following
points are beyond doubt :—
1. The conversion of prunings into humus is
brought about by the action of fungi. These
fungi are for the most part saprophytic, ¢.¢. they
Jive on dead substances.
2. Asaprophyte can be converted into a para-
site on the living tea bush if itis habituated to
tea prunings,
3. Allour tez root disease fungi are initially
saprophytes, Even the tea leaf fungus, Gray
Blight, lives far more vigorously as asaprophy te
than as a parasite.
4. Our newest tea root disease is caused bya
fungus which liveson pruninys, either buried
or on the surface: likethe others, itis an edu-
cated saprophyte.
As practical results are preferred, I quote the
following from a recent letter about the newest
tea root disease:—
‘‘Tam sending you some dead tea stumps
and roots. For the past nine years each
field, where possible, has had its prunings
buried atthe time of pruning, which would be
every second year. One hole to every four trees
every othertime. Anapplication of Basic slag
and Potash is added to each hole. The following
year the fieldis treated with artificial manure.
In the particular field from which these
roots are taken, there is a very considerable
number of deaths,”

‘*COMPRESSED’’ INDIAN TEA
IN INDIA.
Ata Meeting of the Indian Tea Association
held last month—
The CHarrMaNn—said that he had to invite
the Committee to consider the recommenda-
tion of the Executive Committee that a
bonus of nine pies per lb. be offered ona mil-
lion pounds of compressed tea to be sold in
India. It would have been seen from the pro-
ceedings of the meetings of the Executive
Committee that this was a proposal which
had originated in London. The attempt to
manufacture compressed tea had been tried, he
believed, tin India, but without any particular
success. At home, however, it was under-
stood that machinery which would press
tea properly had been invented ; and he was
informed that certain firms were prepared
to interest themselves in the project and to
giveit a trial. Although the Executive Committee
did not expect any very great results from work
in India, they recognised that there was a great
potential market in the country, and they
were willing therefore to make further efforts.
Mr. H. C. Brac—then proposed and Mr. W D
Cowan seconded :—
‘* Phat a bonus of nine pies per Pound be offered
on a million pounds of compressed tea to be sold
in India during the year ending 31st March, 1910.”
The resolution was carried unanimously.

VISIT OF A LONDON TEA MAN.
INTERVIEW WITH MR. A. MANN OF
MESSRS. JAMES FINLAY & CO.
INTERESTING INFORMATION ON INDIAN TKA.
Mr. A Mann, the Visiting Agent of Messrs.
Finlay. Muir & Co., who, during the last few
months, has been all over the North India tea’
gardens of the firm, and, latterly, the South
India properties prior to spending ‘a month
on the Ceylon estates, arrived in Ceylon recently
and, in a conversation with a Ceylon Observer
representative gave some interesting informa-
tion relating to Indian tea,
Prospects OF THE INDIAN TEA Crop,
Mr. Mann was first asked what were the
prospects of the coming season’s Indian tea crop,
to which he replied: ‘‘ Not very good. Just
now North Indiais suffering from a severe
drought which had not broken when I left.
We had only some two inches rainfall from the
end of October up to the middle of February,
and that fell in decimals—so that really it was
not much use. Dibrugarh, though, has had a
good rainfall, and they should start fairly well.”
Is the area cultivated likely to extend ?
No, it is not likely to extend much.
Labour is the difficulty and itis getting more
acute every year. ‘here is such a demand for
it in mines, factories, railways, and that sort of
thing.
WEEDING.
What are your views on the advantages or |
otherwise of Indian methods of cultivation
as compared with those of Ceylon?
Well, of course, we stick to our ideas. Wee-
ding would never do with us, ours is such a stiff
soil that it has to be turned over. Wedon’t do
weeding atall. We goin for one very deep hoe
in the cold weather and five to six light hoeings
throughout the year. We have no plucking from
the end of November till the middle of March,
the bushes rest then, and we prune every year.
The climate and soil are, of course, quite dif-
ferent. The soi] here 1s very open and friable,
ours is not, ours is stiff. Weeding
SEEMS TO SUIT CEYLON
but it would simply ruin the North India gar-
dens, I should think. The system pursued in
both places is the correct one for the climate
and soil.
THE BURYING OF PRUNINGS.
Do you believe in the burying of prunings ?
Most decidedly. I am very strong on that
point, and [ would go so far as to bury all dis-
eased prunings even, unless there were a fungoid
growth, They contain the nutriment ot what we
want to put back in the soil and I consider it is
THE Brest MANURE
of any we can get. North Indian planters are
very strong on burying prunings.
Do you hold the same opinion with regard
to Ceylon gardens ?
I do not see why these remarks should not
apply to Ceylon. As far as I have seen, both
here and in South India I should think the
burying of prunings would be most advanta-
geous to the plant,
and Magazine of the Ceylon Agricultural Society,
Then,of course,you do not believe in burning ?
1! would only burn fungoid growth, thread
blight and that sort of thing, The fungus
rows on underneath the soil when it is covered.
With regard to other prunings ! ehould be very
strong on burying them, |
Tua BRICKS,
How do you view the proposed campaign to
promote tea drinkmg among the: natives of
India by the sale of tea bricks ?
Itis away, of course, of getting rid of the
poorer qualities of tea; but what we want to do
is to get atthe agricultural people, so that Lhe,
will buy it. Not only the people im the towns
but the people in the agricultural districts,
How do you recommend doing that ?
Messrs. Andrew Yule & Co. carried outa
scheme somo years,ago of solling pice packets
to the natives, but it seems to have come to
nothing. The only way to do it is to have
AGENTS TO PUSH IT
and get the housewives in agricultural districts
to get a liking forit. It would be a difficult
thing to get it introduced all over, it would
take time. The bricks are made of a poor
quality of tea because the noorer class would
not pay the price for a good tea. The better
class natives can always buy the ordinary tea.
Altogether, I supposo, itis notagreat success?
Well, it has not been a success so far.
Do you think it will be ?
* There is an idea of compressed tea now which
may have a better result. The bricks will probably
be abcut five pounds in weight, in factthey are
already made so for Afghanistan. It takes a
LONG TIME
to get rid of them, however, and the system has
not made much headway.
If they don’t make much headway in Afghan-
istan, [ suppose they won't make much headway
anywhere else ?
Jam afraid not—no. Of course there are so
many people downin the agricultural districts of
Bengaland round there that if it were onceintro-
duced there would be a big demand for it, once
they take a liking for tea,
Do you think they are likely to get a liking
for it ?
Oh, I think they will. Itis just a matter of time.
It may be successful then and it may not?
I think if they have the funds to keep it long
enough before the public it may ; but, as I said
before, it is not reaching the town people so
much, asthe people in the country, the ryots,
that should be aimed at.
There is then a prospect of a demand being
created if you can keep long enough at it ?
I think so, yes.
How are the bricks made?
They are simply pressed by being hammered
into amould, by hand, with an iron mallet.
It is asimple operation, then ?
Oh, yes, it’s simple enough. Of course ifit were
to turn out a success, machinery would have to
bo introduced to do it on a bigger scale, becruse
it takes a long time by hand,
Could they be improved ?
They could be improved by machinery.

RUBBER IN COCHIN.
Leasu or Forest Lawns,
With reference to the advertisement in this
issue from the Diwan of Cochin, the following
is an oxtracth from the Order of the Cochin
Govornment regarding the leaso of forest lands
for the extension of rubber cultivation. The
Order opens with a review of the previous action
taken by the Durbar with regard to, leasing
forest lands for planting of rubber and coflee,
and then goes on to say :—
It will be observed from the above review of
the previous correspondence on the subject,
that leases of forest lands for coffee or rubber
cultivation have hitherto been granted more or
less as au experimental measure and that no
definite policy has been laid down to regulate
the grant of such leases. Whereas in some cases
applications have been refused, in others they
were granted, and no consistent policy has
hitherto been followed in disposing of the several
applications that wore received from time to
time. Before formulating a definite policy on
the subject, it was necessary however to watch
the progress of rubber cultivation started by the
planters in the Palapilly, Puthucad and Vellani-
kara Estates and also to ascertain whether the
forest lands of the State are well adapted for
the successtul cultivation of rubber. Mr. Cecil
Hall, one of the most experienced planters of
the State, was deputed to inspect forest lands
in the Sholayar valley, and he made a report as
to the
EXCELLENT FACILITIES FOR RUBBER CULTIVATION
in these parts. The Forest Working Plan Officer,
Mr Govinda Menon, also reported that timber
extraction would be prohibitive in this locality.
In regard to the experiments already made,
careful enquiries have now been made and it is
reported thatthe results achieved so far have
been eminently satisfactory and rubber is grow-
ing remarkably well in all the three estates. In
a pamphlet issued by the planters of Southern
India on rubber cultivation in Travancore and
Cochin, reference has been made to Covhin
rubber in the following terms :—
** Rubber was first planted on any scale in 1905, when Mr
KE Nicoll obtained a grant of forest land at Palapilly,
behind the Government Teak Plantation. This was a well
situated block, at the foot of the hills, with the Chemoni
river running through the centre. Some forty acres were
opened in 1905, and later on, in the same year, Mr G
Windle, on behalf of a Syndicate, took up an adjoining
block of forest now called Puthucad, In 1906 there were
some 300 acres opened on each place, and in 1907 the
balance of the land was opened, Puthucad being in all
’ some 65) acres and Palapilly nearly 500, the two places
making a fine sheet of over 1,100 acres of rubber. The
conditions here are very favourable, the elevation being
almost sea level, rainfall about 150 inches, and surrounding
hills sheltering the basin from wind. As a result growth
has been remarkably fine and, according to those who
have seen both, it may challenge comparison- with fine
Straits growth. The plantations are some eight miles by
cart road from the Puthucad station on the Cochin Railway
and about 20 miles from the Coast. In 1906 also a grant of
Government. forest, six miles from Trichur Railway sta-
tion and lying on the main road from Trichur to Palghaut,
was obtained by Messrs. i G Windle and R E Campbell
Gompertz, who’ opened 400 acres and subsequently
disposed of the block to the Cochin Rubber Company,
Ltd., of Colombo, in whose name the Government
title was issued. This consists of{1,000 acres in all, cf
which 400 acres were opened in 1906, 200 in 1907, and 2U0 in
1908, 200 being forest. Mlevation and rainfall are much the
same as at Puthucad and Palapilly, and growth has been
excellent, There are, therefore, at present some 1,900 acrag
298 The Supplement to the Tropical Agriculturist
of Para opened in Cochin. Many other applications for
land have been made, but were refused by the Durbar
(Cochin Government) onthe ground that it had to be seen
whether rubber would be successful. There seems no rcom
to doubt this now, ard itis to be hoped that further land
may be available tothe public for tea as well as rubber.
The forest slopes, which are now being tapped by the
tramway might reasonably be surveyed with the view of
opening suitable parts; there are probably 50 to 1,00,000
acres which would grow one or other of the above products
without unduly interfering with forest resources,”
The last observation is fully borne out by the
inspection report of Mr Cecil Hall who inspected
the lowelying hills and the valleys adjacent to
the tramway and the rivers. His preliminary
report contains the following remarks :—
“T found a very large area of forest land eminently
suitable for the cultivation and growth of Para rubber
(Hevea Brasiliensis) as well as for tea and also a good
deal of land about 2,000 feet elevation which would grow
tine coffee and tea, but which is situated at too high an
elevation for rubber cultivation. I found most excellent
and suitable land for rubber both sides of the forest
tramway from Parambikulam to where the tramway enters
the low country and throughout the entire length, on both
sides of the Sholayar river throughout its entire length
and also on the both sides of the Parambikulam river
from Orukombankutty whether this river leaves the tram-
way and to where the river empties itself into the low
country below the Adirapilly water-falls. Branching off
from the tramway and the two rivers, there are several
large valleys very sheltered and ideal spots from a planter’s
point of view.”
Having regard to the enquiries made from
time to time and the successful experiments on
rubber cultivation in the State, His Highness’
Government have now resolved to grant further
leases of forest lands for the cultivation of rub-
ber. The enquiries as to forest requirements
show that lands to the extent of 5,500 acres in
the valleys of Chemmoniand Muppilli rivers in
the Palapilly forests, almost adjacent to the
Palapilly and Puthucad estates where rubber
has thrived so well, can well be opened out for
rubber without prejudice to the forests. His
Highness’ Government are, therefore, prepared
now to
RECEIVE APPLICATIONS FOR THIS EXTENT OF
5,500 ACRES
as wellas for any extent of the land reported
upon by Mr Cecil Hall in
SHOLAYAR VALLEY UP TO 10,000 ACRES,
for rubber cultivation on the following terms :—
a. The areasavailable for assignment will be demarcated
into 500-acre blocks, Any person may apply for several con-
tiguous blocks.
b. The upset price will be R25 per acre or R12,500 per
block and include the value of the forest growth, sub-
ject toclause(l) infra. The lease will be sold to the highest
idder at an auction to be held at Trichurin the oftice of
the Conservator of Forests on the 14th June, 1909.
c. The sale will be conducted by the Conservator of
Forests and subject toconfirmation by the Dewan, The
successful bidder shall, at'the time of sale, pay down 25 per
cent of the purchase money and the balance thereof shall
be paid in full within 30 days after the communication to
him of the conformation of sale by the Dewan, failing
which he shall forfeit his deposit money and be held respon-
sible for any loss the Sirkar may sustain by resellng the
lands either by public auction or private contract.
d. The Bewan reserves to himself the right to confirm
or cancel any sale without assigning any reason.
e. Bona fide application from planters and from the
natives of the State who wish to investin rubber and
pioneers of rubber plantation in the State will be given
preferelce. ~
j. Thelands will bocharged with a minimum assess-
ment of eight annas per acre for the first eight years of the
lease and thereafter with an assessment of R2 per acre.
The rate will be subject to enhancement in the open com-
petition. This assessment shall be payable by lessees
whether the rubber trees shall have begun to yield or not.
g. All payments to be made by the lessees shall be
recoverable as arrears of public revenue under provisions
of the Cochin Revenue Recovery Regulation.
h. Inthe event of the lessees raising any catch-crops,
which, in the opinion of the Conservator of Forests, may
be likely to render the lands so cultivated permanently
unfit for the growth of valuable timber trees, the lessees
shall be liable to pay a fine of R5 per every acre so cuiti-
vated, and the crops so grown shall, at the option of the
Conservator, be destroyed.
i. Thelessees shall not be entitled to any minerals or
allowed to quarry laterite, ground granite, etc., free of
seigniorage, except for the bona side estate buildings.
_j. No fire otherthan may be for ordinary use (in dwel-
lings or factories upon the premises) shall be set to within
the area hereby assigned unless a clear week’s notice
thereof shall have been given to the Conservator and his
consent shall have been obtained.
h, All existing rights of way shall be kept open.
t. The timber rights may, if necessary, be sold separately
or with the land. His Highness’ Government reserve to
themselves to sell both together or separately to the best
advantage. :
m. Asthe measurement of the land previous its being
cleared may be more or less incorrect, the land to be again
measured after it has been cleared, and the permanent
rent to be assessed onthe area thus correctly ascertained.
n. The land to be enjoyed by the lessee as long as the
rent is regularly paid ; but in the event of the rent falling
in arrears for more than one year, his improvements
thereon as well as any other available property to be sold
to make good the same.
o. Should the lessee relinquish the land befvere it has
been cleared and planted, he shall pay to the Sirear the
full rent of R2 from the day on which the land was given
to him to the day on which he notifies to the Sirecar that he
has relinquished it.
_p. His Highness’ Government reserve to themselves the
right of constructing any roads, channels, or public build-
‘ings required forthe public convenience and for making

MR. FRITZ ZORN ON THE RUBBER
INDUSTRY IN 1908.
The namo of Mr. Fritz Zorn of the well-known
Stock Exchange Firm of Messrs. Zorn & Leigh-
Hunt is not unknown in Ceylon and we ven-
ture to think few will disagree with us when
we pronounce him one of the most careful
students and penetrating critics of the rubber
industry in England today. My, Fritz Zorn
is perhaps best known through his handy and
useful manual of rubber planting Companies,
comprising particulars of the leading Com-
panies engaged in the cultivation of rubber
(either alone or in conjuction with other crops)
in tho Straits Settlements, Coylon, Borneo,
Java, Sumatra, Southern India, &c., &&. The
third edition of this book revised and brought
up-to-date reaches us by this mail. It contains
many new features including a review of the
year 1908 in relation to rubber planting ; a table
of fluctuations in the price of rubber for
the last three years ; and highest and lowest
prices of the leading Rubber Companies’
shares during 1907 and 1908. Another fresh
feature, which will be found useful, is tho
inclusion with regard to a number of pro-
ducing Companies of ‘‘ unofficial estimates ”
of the crops for future years. ‘The first of
these uew features we find pregnant with
shrewd comments and interesting deductions
from the experience of the past year, upon
which is. founded a eareful prediction ol
the outlook for the future. The review is
in our opinion quite one of the most useful
of the 1908 rubber year which we have yet seen.
The soundness of the authority and the interest
of his subject warrants us referring to it
at some length. Mr Zorn starts with a
reference ‘to the slump of 1907-1908, and—after
commenting on the profound ignorance of the
facts which led to the depression being attri-
buted to the overproduction of plantation
rubber in the Middle Kast—remarks that the
Wild Rubber industry must continue to domi-
nate the situation for a considerable time to
come; and as cultivated rubber can be produced
at avery much cheaper rate than the Brazilian
product, the fear of over-production must fora
good while be a mere bogey, so far as plantation
enterprises are concerned. The recovery in the
value of the raw material, which has taken place
contemporaneously with the passing away of the
depressed conditions in the United States,
which had been the true cause of the fall,
he regards as affording ample proof of this.
The figures regarding supply and demand_ in
1908 are carefully dealt with and a good deal
of space is then devoted to the ‘‘ Share
Market.” It is considered noteworthy by Mr
Zorn that the recent improventent in the share
market has been nothing like proportionate to
the recovery inthe price of the raw material
and, having regard to the increased profits
which will accrue from the rise in rubber to
companies that have reached the producing
stage, he considers that at the existing quota-
tions rnbber shares offer considerable scope to
the investor. In spite of all difficulties, how-
ever, Mr Zorn declares the market has shown
a broadening tendency during the year and the
- per lb. as the cost of production for 1908.
209
circle of investors putting their capital into
the planting industry is steadily growing. He
eres the Exhibition at the Olympia credit tor
eing an important factor in bringing about this
result. Dealing with the crises through which
rubber passed in 1908 Mr, Zurn summarises
its effects as follows:—
First: The non-expert Rubber Investor got
frightened by the slump and threw away his
shares at rubbish prices.
_ Second: The ‘ plungers” both here and
in the East who (with plenty of expert know-
ledge of the industry, but no proper sense
of caution) had involved themselves in une
wieldy commitments, both in regard to planting
and share operations, for the most part had
to ‘*go under.”
Third : New planting has_beon brought
down to much more reasonable limits, as
there has necessarily been a general curtail-
ment of extensions,
Fourth : The management of the estates
has been carefully overhauled and drastic
economies effected, thus reducing the coat of
production,
_ Fifth : ‘f Wild cat” promotions of worth-
less new Companies has been rendered practi-
cally impossible,
There is an interesting paragraph on the cost
of production of plantation rubber. This iz
put by Mr. Zorn at present at about 1s 6d per
lb. Personally we shail be very much surprised
if im Ceylon, at any rate, before many yoars
the cost of production will not have decreased
by half this sum.’ As estates gain experience in
dealing with larger quantities and greater num-
bers of trees, the tendency will be in the
direction of reduced cost. Who would believe,
when tea in Ceylon was as young an in-
dustry as rubber is at present, that the cost
of production would ever be reduced to the
existing level? Already the costof rubber sold
locally from Vogan estate has averaged 104d
The
review concludes with a reassuring pronounce-
ment on ‘The Outlook”; under this head Mr.
Zorn remarks that the annual reports which have
Bepesred during the past twelve months have
afforded a striking illustration of the advantages
of low capitalisation when bad times have to be
faced ; he adds that it cannot be denied that
a moderate basis of capitalisation isone of the
merits of most of the leading Rubber Planting
Companies. Alluding to the Brazilian ‘‘valorisa-
tion scheme” he pointsout that the main im-
portance of the suggestion, asfaras the Eastern
Planter is concerned, lies in the effect upon
price and remarks that the scheme is at the same
time a significant indication of the way in which
Brazilis waking up to the potentialities of
Eastern Rubber planting. It is hardly to be
expected (and for the sake of expanding demand
it is not to be desired) that rubber should main-
tain its present high quotation, but Mr Zorn
thinks that the fall, when it does come, will not
be aserious one. He concludes as follows :—
The underlying strength of the present posi-
tion lies in the fact that, taking the World over,
consumption of Rubber is more than equal to
production, Consequently, the whole position
500
of the industry is remarkably healthy, and in-
dications point tothe price remaining for several
years to come at a level which will secure ex-
ceedingly handsome returns to well-managed
Plantation enterprises while in the more distant
future there can be little doubt but that culti-
vated Rubber will gradually displace the wild
product as a mere case of ‘survival of the
fittest.” Whatever may lie ahead of wild Rubber-
producing concerns, therefore, the outlook for
Plantation Companies appears distinctly bright.
Altogether the manual is a most conveniert one
for reference and should be on the office table
of every one interested in the industry.
THE MINIMUM COST OF RUBBER
PRODUCTION
in Ceylon at the present time—next to that of
the Ceylon Tea Estates Co. (94d.), must surely be
that attained on Vogan and Iddagodde estates
in Kalutara, of the famous Company known by
the former name. We are told that the cost of
tapping only was 38-94 cents per lb., while the
whole cost of production of the year’s crop of
23,246 Ib. (5,746lb above estimate) averaged 62
cents or just under 103d per lb. This included
cost of tapping knives, upkeep, supervision, We.
Even this will probably show an appreciable re-
duction in 1909, for the new system of tapping
is to be entered upon and the crop—estimated
at 60,000 lb. or more than double that of 1908
—it is anticipated may be very much larger.
For the present it is cautiously stated that the
contract sale of biscuit and sheet at R3-10 will
give a profit of R250 per 1b., making cost of pro-
duction 60 cents only. We shall not be surprised
if it is brought down to 55 cents or even below.
THE PRUNING CF RUBBER.
The question of pruning is still an unsettled
one, and the’ majority of planters regard top-
ping with disfayour, At any rate thumbnail
runing is preferable to cutting ofa top two or
tires inches long. In the latter case a leader
never grows up; two or three branches come out’
of the same level and at a wide angle. Ina year
‘or two when their leaf spread is larger ono or
more of these branches breaks off leavivg a
‘gaping wound in the stem, and which offers an
entrance to wound-fungi. I think it is not wise
to assert that pruning should or should not bo
followed. Much depends on the situation, the
soil, and the rapidity of growth of the trees.
Certain trees branch naturally at a suitable
height ; others grow up to 15 feet and higher
without branching and these might certainly be
helped by judicious pruning. It is generally
recognised now that all branches should be cut
off when quite young up toa height of at least
10 feet, as tapping will ultimately be done to
this height at least; a good clean step is wanted,
.and branches or big scars left where old strong
branches had been cut off will only interfere with
“high ‘tapping. Formerly when two _ branches
grew off near the ground both were allowed to
develop on the view that double the tapping
area would be available. Planters with old trees
find this isa mistake. Neither grows as thick
as either would have done if alone. The foli-
age of each is one side only and such trees being
lop-sided are very liable to suffer from wind.
The Supplement to the Tropical Agricultiunist
“WARTS” AND ‘* PwWwAg.?
The growths, commonly called ‘ warts ” or
“peas,” are to be found on nearly all trees. Tap-
ping does not appear to induce them as they are
found on untapped trees of three years and
older, U believe they are dormant buds. They
should be taken out when quite young ; this is
easily done by atap from a hammer or witha
strong knife. The wound soon heals over com-
pletely. The practice of many planters having
their old trees examined systematically at perio-
dical intervals for these excrescences is worthy
of wider application. The rough outgrowths,
often several square inches or even square feet
in area, which usually begin at the bottom on
trees where tho early tapping has been bad,
seem to be a disease not due to any parasitic
organism but to some derangement in the inter-
nal economy af the tree induced perhaps by:
severe tapping.—W J GaLLacueEr in the Séraits
Agricultural Bulletin for March.
SCARCITY OF TAPPERS IN THE F.M.S.
We hear that, although there is no lack of raw
or unskilled agricultural labour just at the pre-
sent moment, many estates which are now
coming into bearing areunable to give their full
possible output of rubber because of the scarcity
of competent tappers. This seems to be due toa
disinclination on the part of managers to train
‘‘tree” coolies to tap, as it has been found that
when they have become more or less skillful in ©
the use of the knife they frequently leave their
original employment and sell their services fora
higher wage elsewhere. However, if this scar-
city of tappers causes fewer young trees to be
tapped and so givesthem longer to mature, we
are quite convinced that it will make for the
benefit of the local rubber industry in the long
run.—Penang Gazette, Feb. 24. j
THE CHIEF RUBBER PEST IN THE
MALAY STATES.
&
We direct attention to the following article
we reproduce from the Straits Agricultural
Bulletin, dealing with the Termes Gestroi,
the rubber equivalent of the shot-hole borer
in tea. It will be seen that the notes in ques-
‘tion refer to flat alluvial land of which there is
comparatively little under rubber here,compared
with the abundance of it in the Malay States.
Whether on this account or for other reasous,
the pest is not so bad in Ceylon ; but it has been
found, especially in new clearings. It is well
that the drastic treatment of it should be under-
stood and the notes elsewhere ought to be per-
used by all planters, especially those in charge
of new clearings or newly planted property. it
will be seen that thorough drainage is one of the
best methods of keeping the pest in check, the
termites seldcm crossing a sub-soil drain except
by a log or wooden bridge, Allsuch. stray wood
should therefore be carefully watched in addi-
tion to other measures being taken, J,
and Magazine of the Ceylon Agricultural Society. 301
“ THRM ES GESTROL.”
In the whole of the past history of tropical
agriculture in tea, coffee, cocoa, cinchona and
spices, there have been four causes for dis-
appointment and an awakening from the golden
dreams with which various enterprises were
originally commenced :—
1. Substitutes. 2. Synthetic production at
alow cost. 3. Over-production. 4. Pests
and Blights.
The first three are beyond the control of
the individual ; and if any reliance is to be
placed on expert opinion, the rubber planter
in the East has nothing to fear from them
in his comparatively new vonture, but the
fourth, z.c., Pests and Blights, comes well within
his scope and it is his duty to leave nothing
to' chance and do everything within his power
to assure the success of the enterprise.
So far we have one blight and one pest which
may be considored as serious, i.¢., Homes senci-
tostus and Termes gestroi,
Fomes semitostus is a blight which, if taken
in hand at once and treated according to the
advice of the Government mycologist, Mr. W
J Gallagher, will, Iam sure, be easily overcome
as we have successfully dealt with the same
class of blight in tea, coffee, etc., by dramage
and application of lime.
. Termes gestroi, however, is
A VERY SERLOUS PEST
and it was in recognition of this fact
that, in my various endeavours to extermi-
nate it, | collected a large number of queen
termites ; these I showed to Messrs. Carru-
thers and Pratt, who were much _ interested,
as the queens evidently belonged to two or
more species and it was quite possiblo the
Queen gestroi, which had hitherto never been
found, was amongst the collection. This re-
sulted in the investigation by Mr. Pratt and
I have been fortunate in being in possession
of the valuable discoveries made by him, for
a considerable time before they were published.
Previous to Mr, Pratt’s discoveries with re-
gard to the habits of 7. gestroi Twas much
afraid that the pest would prove to be a heavy
handicap to the Malay Peninsula in its com-
petition with other rubber-producing coun-
tries in the future and a serious though un-
seen and therelore unrecognised loss, in the
present. [ am now quite satisfied, however,
that it can be altogether eradicated, In-my
endeavours to exterminate tho pest as expe-
ditiousiy and as cheaply as possible [I have
arrived at some conclusions and methods which
may be of use to my brother planters. The
following notes refer to flat alluvial land:—..,
Metuops or ExTERMINATION.
On OLp Rupper TrEES.—It has to be deter-
mined whether 7’. gestroi establish their termi-
taria in the rubber trees tnemselves and on
this point I have no data. If it should prove
to be the case, fortunate is he who discovers
an insecticide, or other means, by which the
Queen cells may be reached, at a low cost and
without destroying the tree, and thereby obtain
the reward now being offered.’ On the other
hand, our success in exterminating the pest
depends upon the skill with which tho runs
aro traced up to their base. If all timber is
collected and destroyed, I feel convinced that
if the attack does not entirely cease it will
be very much diminished.
On Youne Russer Hsrates,—I have found
it cheapest and best to make a systematic search
field by field and line by line for all timber
which 1s known to be favoured by 7. Gestroi, cut
them open with an axe or cross-cut saw and if
they contain the slightest trace of the enemy,
destroy them by burning.
The danger of scorching the surrounding plants
may be entirely done away with, oratleast greatly
minimised, by burning in a trench keeping the
fire covered with green stuff, and shielding the
surrounding trees with sheets of corrugated iron,
These should not lean against the rubber troes
but be supported by sticks a short distance from
them ; even if two or three rubber trees are de-
stroyed by fire in this way, the damage done is
more than compensated for, by the fact that one
T gestrot termitarium is
CAPABLE OF DESTROYING A SCORE Ok
MORE OF TREES
toa distance of two or three hundred feot.
Where there is a sale for timber or charcoal,
sound Meranti trees may be sawn up with ad-
vantage and Kumpas can be converted into first
class charcoal.
A close watch should always be kept on land
that has been cleared of timber, and if a tree is
seen to be attacked, every endeavour should be
made to discover the source of infection, which
will invariably be found to be a buried root or
stump, from which the termites make their way
in search of food by means of tunnels. These
may be found at a depth of 6” te 3’ below the
surface of the ground. In flat land, I have never
found them below the sub-soil water level, which
of course is regulated by the efficiency of the
drainage system.
Theso tunnels are, as a rule(as Mr. Pratt says),
sufficiently large to admit the imtroduction of
an ordinary microscope slide though some-
times smaller, they are perfectly smooth and
are lined, with. a red substance, probably tho
excreta.of the termites which takes its colour
from the timber on which they have been feeding.
This colouring greatly facilitates the following
up of the tunnels ; but it is by no means an
easy matter until the coolies become practised
at it and see for themselves that they are doing
real good and not merely following out some
mad scheme of their masters, When the direc-
tion of a tunnel is lost, it is very diflicult to
pick it up again. I have found the surest
means, of not losing it, is to use a piece ot
thin flexible wire or strip of cane as a probe.
Pass it into the tunnel as far as it will g0,
remove the tcp soil carefully with a chunkol,
then break open the run to the end of the
probe. Pass the probe in again and proceed
as before until the termitarium is reached.
To find the tunnel or to pick it up again should
it be lost, Ihave found it a good plan to cut
a trench round the tree attacked or the spot
where the run was lost. This trench should be to
302 The Supplement to the Tropical Agriculturist
the depth of the wator level, say two feet, and
should be examined the next day when it will
often be found that the termites have made their
way across by means of a mud casing, thus
determining the direction of attack.
It isa tedious matter at the best to follow up
these tunnels and it is on this account that I
have found it
EXPEDIENT TO EXAMINE ALL TIMBER
which L know to be likely to contain termitaria
before resorting to this means thereby saving
much time and expense.
At first I gave rewards for the Queens and have
collected in this way upwards of seventy un-
doubted specimens, but liind that by this method
the coolies waste much of their time in break-
ing up every smaller piece of the termitaria in
order to find the Queen colls,
When a log or root containing the termitarium
has been discovered and destroyed and the
sround around it dug up it may safely be con-
cluded that the Queen has perished with therest
of the individuals, Usually itisonly necessary
to trace up the runs in the case of anest occurring
in a buried stump or root,
The first field I systematically cleared of all
timber five months ago has since shown no sign
of the pest. This field was planted with Ram-
bong about six years ago, it was allowed to lapse
into bluker and was interplanted with para in
1906, The only remaining timber was Kumpas
of which there was a considerable quantity. Tho
attack on both Para and Rambong trees was
particularly virulent in this block but has now
entirely ceased.
‘As Mr Pratt very truly says, owing to the cryp-
tic habits of termites itis very difficult to de-
termine when a tree is attacked until it falls
down; but during the wet season in October,
November, December and January the termites
frequently make their appearance above ground
and this fact I think should be taken advantage
of, by marking in some way all the trees on which
the termites make their appearance, for even if
they cannot be attended to at once, one would at
Yeast know where to look for them in the future.
T am afraid that some planters are lulled into
a sense of security by the fact that none of their
young trees have been attacked; it would be well
worth their while to make asearch for 7. ges-
troi in the timber lying in clearings andif found,
take steps to eradicate the pest, for although
trees may not. be attacked now, or perhaps for
a year or two to come, they will be attacked
sooner or later if 7. gestroiis present.
J have not found a single tree attacked so far
in my forest clearings, but I know that 7. ges-
troi is present. On the other hand in reclaimed
land, owing to the decay of most of the
timber, 7’. gestroc has wandered forth in search
of fresh fields and pastures new it has made
its presence evident by attacking young rubber
trees.
On Fourore Orearines.—In these again the
importance of discovering the forest trees most
favoured by 7’. gestroi is evident. I cannot
speak from practical experience, but the obvious
course to p ursue would be tocut down all trees
known to harbour 7. gestroi and allow them to
dry for as long a period as possible, prior to
the felling of the land. Many of these
trees would be then destroyed in the burn
and those which remained could be burnt out by
piling over them the surrounding timber, This
would of course enhance the cost of clearing
perhaps by $10 or even $20 per acre, a small con-
sideration in comparison to the damage that
may be effected by T. gestroi.
Further advantages of more thorough clearing
would be less likelihood of vacancies caused by
Fomes semitostus anda saving in the cost of
weeding, in fact of every other work carried on
in the clearing together with easier and
consequently more efficient supervision.......
DRAINS AS AFrscTiING TeRMES GEstroI.—I have
not in asingle instance found the runs of ter-
mites crossing a sub-soil drain, excepting by
means of a fallen log or wooden bridge. It fol-
lows, therefore, that the more frequent the
drains, the more circumscribed wili be the attack
of the termites, provided that iron or concrete
bridges are used instead of wooden ones and
that all timber lying across drains be removed.
The mound termites, 7. Walayanus, and T.
carbonarius seem to prefer the edge of adrain
for the construction of their termitaria but ges-
troi apparently considers the suitability of timber
only and not that of soil in choosing its home.
When nearing adrain the 7. gestrov runs are
usually found at a greater depth than elsewhere.
This is no doubt due to the facility with which
the termites are able to penetrate the soil which
has become freer owing to good drainage. ... .
INSECTICIDrS vor THE HRADICATION or TERMUES
GESTROT,
To anyone who has followed up a 7. gestroi
tunnel, ramifying as it does sometimes for hun-
dreds of feet, or has seen the interior of a termi-
tarium with its myriads of individuals, the utter
futility of attempting to eradicate the pest by
means Of insecticides must be apparent, but
insecticides will be found useful in killing the
comparatively few individuals which continue
their attack for some time after their termi-
tarium is destroyed. I see that the custom of
applying lime to the tree attacked still continues
on some estates. This is utterly useless as a
preventative, or even as a means of keeping the
termites in check; but it is useful as a means of
marking the trees attacked.
CroraLARIA AND GREEN MANORES AS AFFECTING
T. GuEstTRot.
Crotalaria is undoubtedly of great advantage
asagreen manure, but it has yet to be proved
if itis 2a means of cheapening the cost of weed-
ing. Thereare two objections to it which can
however be overcome.
Firstly, the difficulty which is experienced in
eradicating 7’. gestroi and Fomes semitostus, will
be enormously increased by the fact that all
timber is hidden by growth rendering it neces-
sary to closely inspect each rubber tree and to
search about amongst the crotalaria for timber
containing 7. gestroi. This can be overcome
by first eradicating the pest and then planting
green manure. Secondly when the green mauure
is eventually killed out by shade, the rubber
tree will experience a shock from their custo
mary supply of nitrogen bring cut off. This can

be obviated by interplanting with leguminous
trees, such as Albezzia moluccana. These trees
together with others of the leguminosa have
been
GROWN WITH GREAT BENEFIT TO TEA AND
COFFEE IN CEYLON
and elsewhere for at least twenty-five years—
such growths as Crotalaria mimosa, etc., being
utterly unsuited to this class of cultivation.
In conclusion there are no grounds for the
alarmist view of the 7. gestrot pest, though it
is imperative that it should be taken in hand at
once and dealt with very thoroughly, andalthough
the initial cost may be heavy, it will be more than
justified by the subsequent saving in expen-
diture, on keeping the pest in check, to say
nothing of the saving in loss of trees.

ROOT DISEASE OF RUBBER.
I have received a number of communications
about the ‘'Fomes” or white fungus root-
disease of para rubber. The disease appears
to be more widespread than I thought when I
wrote in the last November number. A com-
mon mistake is cutting the trenches too broad
—this demands extra and unnecessary labour,
and the excessive quantity of earth talon cut
covers the inner area round the diseased tree
so much that the turning-over does not go deep
enough, Where circumstances do not allow of
the outer trenches being made, the adjacent row
of trees should be examined from time to time.
Crotalaria striata is also attacked by a root
fungus, but up to the present I have not been
able to infect healthy Para rubber from diseased
Crotalaria, Planters who have sown Crotalaria
should watch their plants carefully and should
immediately notify the Department of
Agriculture if any die or even look unhealthy.
Itis extremely important to know tho extent
of this Crotalaria disease and if Para is immuno
to it. The symptoms of diseased Crotalaria are
much the same as those described for root
disease in Para but of course not so easily
noticed.—W. J. GALLAGHER.

THE GOLOMSO PRODUCE MARKET.
DesiccatED Coconut—Cacao—anpb Frpre.
The recent drought, combined with the de-
structive cyclone not long ago, led to a shorter
output of coconuts, with theresult that desic-
cated coconut went up in prico by leaps and
bounds, Local exporters did not anticipate
that an easier tone would prevail for some time
to come; but, contrary to these expectations,
we learn that the ‘‘fine” grade now has a
market value of 15% cents per lb. No causeis
attributed for this decline; but it is conjectured
that the financial or trade position of America
is largely responsible for the unexpected change.
During the past year the shipments of de-
siccated coconut to Australia had materially
declined—from 1,236,767 1b. in 1907 to 951,626 1b.
in 1908. Whether this is—or is not—owing to
the establishment of a costly desiccating factory,
the only one in Australia, or perhaps outside
Ceylon, it would be interesting tu know. This
factory is at Paramatta where as ‘Messrs.
Megeitts, Ltd.,” Messrs. Thompson, Fraser, Ram-
say, Proprietary Ltd., who are the principal
shareholders, are carrying on a flourishing busi-
ness. Thecozonuts, which are principally ime
ported from the Solomon Islands, Fiji, are said
to possess a thicker kernel than the Ceylon
nuts, but their productive capability of the
desiccated material falls far short of the local
nuts. For instance a ton of desiccated coco-
nut would require nearly 6 tons of Fiji nuts,
whereas the same quantity can be produced
by about 43 tons of Ceylon nuts. It is only
lately that, through the instrumentality of the
firm above-named, a reduction was obtained
from the Shipping Conference of the rate of
freight ; but unless the market for the local
nuts declines, it is thought in some quarters
that it will some day be itnpossible tor the
Ceylon to compete against the Fiji product,
This year to date, however, the exports to

The late season's cocoa crops have been very
unsatisfactory, for the supplles have been un-
usually short, and the beans are much smaller
than the average size. Climate conditions are
no doubt answerable to a great extent for
these results; but at the same time an impetus
is thereby given to producing centres in other
parts of the world. The latest cabled advices
from London intimate that the market there
for the local product has advanced.
The absence of rain has contributed in a laree
measure to an abnormally big output of mattress
fibre during the present season. Millers have
therefore, had the opportunity of drying their stuff
304 The Supplement to the Tropical Agriculturist
with the result that there is a proportionately
larger quantity available locally. Despite the
advanced market in regard to copra and coco-
nuts, fibre has maintained a practically pheno-
menal local market value. The latest trans-
actions have been at R1'60 per cwt. in bundles
delivered at wharf; but should the weather
change in any marked degree, millers will be
placed ata disadvantage inasmuch as they will
not have the same facilities for drying. The
failure of the N.-H. monsoon may, perhaps, be
counterbalanced by the advent of an earlier
South-West. In this latter event, the transport
of fibre from the mills outside Colombo to the
Metropolis will be greatly hampered and
there is every probability of the market showing
a decided advance in the near future. For the
present Millers hesitate in making forward

HOW VANILLA IS GROWN
iN HAWAII.
Process OF PoLLENATING THE BLOSSOMS AND
CurING THE BEANS—PROFITABLE BUSINESS,
The growing of the Vanilla bean of commerce
has attained considerable importance in Hawaii,
where a number of successful small plantations
have been producing for a number of years.
Jared G Smith, late director of the United
States Agricultural Experiment Station in
Honolulu, gives the following interesting des-
cription of the growing of vanilla in his book,
“Agriculture in Hawaii’ :—
‘‘The vanilla bean is the cured and fermented
fruit of a climbing orchid. The finished pods
are very dark brown or black, glossy, somewhat
wrinkled on the surface, from five to eight inches
long and about as thick as a lead pencil. The
vanilla extract of commerce is simply an alco-
holic extract.
“The vanilla plant is grown either on a trellis
or is planted at the base of a tree so that it can
clamber up the trunk. Any soil is suitable,
provided the drainageis good. It grows well
ip regions or abundant rainfall onthe Kona
(south or southwest) side of the islands. A mean
temperature of 65 to 75 deg. gives good results.
“The plants are propagated from cuttings,
which are simply lengths of the vine itself,
from two to six feet long. The length of the
cutting has some relation to flower produc-
tion, the longer ones yielding flowers in a
shorter period. The leaves are cut from the
lower end of the cutting and the stripped
portion of the stalk is buried horizontally under
two or three inches of soil and rotting leaves.
The upper end of the cutting is fastened to the
trunk of the supporting tree to which it soon
becomes tightly attached by its aérial roots.
“The vanilla plant begins to flower during its
second or third year and continues flower pro-
duction until seven or eight years old. Culti-
vation consists in keeping down the weeds and
underbrush in the plantation.
“The vanilla plant only bears pods when the
flowers are hand pollenated. This is a delicate
operation not difficult) to learn. Any one who
attempts if becomes quickly proficient so that
a good many flowers can be pollenated in the
course ofa day, The pod matures in from six
to eight months, becoming hard, thick and
greenish-yellow. They are gathered before ripe.
“The curing process is a somewhat compli-
cated one. After gathering, the green pods are
spread out aud exposed to the air for 24 hours,
being roughly assorted into grades according to
size. After being graded, the pods are sweated
between the folds of woollen blankets exposed.
to the heat of direct sunshine. During the per-
iod of fermentation the pods turn dark brown,,
become soft and leathery and sweat freely.
The pods are manipulated for several days
until the proper degree of colour and aroma
have developed. After the fermentation they
are dried in the sun for a few hours and fin-
atly in cloth covered trays in the shade with
gentle heat. When fully dried, that is when the
pods no longer lose weight, but are still moist
and pliable to the touch, they are packed tightly
in tin boxes and are again manipulated in bulk
for one or two months. When completely cured,
the pods are sorted to size and colour, tied in
bundles and these packages packed in. tin-lined
boxes. which are soldered when full.
‘¢The yield per acre in Hawali'has been esti-
mated at about 13,000 pods, producing about
120 pounds of finished vanilla beans fully cured
and ready for tho market.
‘“‘The industry is a very profitable one for
persons having sufficient means who will give
this industry their personal supervision. The
price of the vanilla bean depends as much upon
the outward appearance of the finished product
as upon its actual quality as indicated by aroma
and flavour. Care is therefore necessary at every
stage in the growth and fermentation of the crop.
‘* Five acres of vanilla in bearing should yield
from $400 to {500 worth of beans per acre per
annum after the third year. There are vanilla
plantations in the Kona district on the-island of
Hawaii and in the Kona district of Oahu near
Honolulu, Much land is still available which is
entirely suitable for the cultivation of this crop,”

RUBBER IN MALAYA IN 19908.
ACREAGE AND PROSPECTS.,
Go,090 Acres Opened Last Year.
Mr. Carruthers, in conversation with a con-
temporary, said that according to the returns he
has obtained, there were, on December 81st last,
37,000,009 rubber trees growing in the Malaya
Peninsula, including the new territory, Kelantan,
with upwards of 2,000 acres already in rubber.
60,000 acres were opened in 1908—40,000 were in
the Federated Malay States—tho total being
rather more than in 1907.
INCREASE IN YIELD,
The yield per tree for 1908 worked out at one
ounce more than in 1907, viz: 1 lb. 14 oz. per
tree. The average increase of girth per annum,
Mr, Carruthers put (at a guess) ab rather Jess
than four inches, because rubber growing in
lalang came along very slowly. He was gladito
and Magazine uf the Ceylon Agricultural Society.
Say green manuring was now being widely and
successfully adopted, though in one or two
instances strange orders had come out from
home to cut out passion flower, &c., though suc-
cessfully established.
It is interesting to state that, before leaving
Kuala Lumpur, Mr Carruthers applied for 180
acres of lalang in Perak Stateto make practical
tests as an estate proprietor of the methods he
advocates. The terms are the usual ones for
lalang land—one cent per acre per annum for the
first seven years and one dollar per acre per
annum afterwards. The place will be locked
after by Mr Carruthers’ cousin, who is on an
estate about 14 mileaway. Mr Carruthers in-
tends to give one spraying of arsenite of soda
and then turn off and immediately plant three
varieties of useful cover to complete the killing
out of lalang, viz., passion flower ; abrus preca-
torius (distinguished by its well-known red
seed with black top); and a new vigna which Mr
Carruthers came across just before leaving and
which appeared to promise well.
Mr Carruthersconsiders the rubber industry
to be of a permanent character, and, although
after lalang the rubber is usually a little slower
in growth for the first few years, he did not
mind whether it took eight years instead of six
in coming to the remunerative stage, consid-
ering the small cost of the planting.
COCONUT PLANTING IN FIJI.
Referring to his review (Fujz Times, Nov. 25th,
1908) of cur Coconut Planters’ Manual, Mr. R
L Holmes of Bua, Fiji, writes under date,
December 14th ;—
-“T have been a coconut planter for nearly 40
years and have often used strong language when
referring to the shameful neglect of the autho-
rities and settlers on Vitilevu comprising fully
half of Fiji. And from end to end of that great
island the coconut trees suffer from what you
will name ‘the so-called leaf disease,’ that
never kills trees, and requires only culti-
vation and suitable localities—in fact, common-
sense to make them flourish. I hope what I
have now set forth may do some good, and
thanks to you largely if it does.”
From the review we quote :—
One of the chief copra buyers in the group assured me that
he learned from Home letters, that Fiji copra ranks the
lowest ot any others in the English market, which means
that the oil therefrom is very inferior. It is not hard to see
the reason why, viz., the large quantity of bad copra sold by
the natives, and accepted by upcountry buyers and mer-
chants. Bought and sold at avery low price, itis thrown
onto the heap of better class, mixed with it, and all
shipped together to Kurope. Grossly unfair to planters
who supply a first class article, as it lowers the value of the
whole. Can the Government not stepin? Appoint an In-
spector, and throw the rubbish into the sea, Natives would
soon change matters by selling only good copra. I see
continually, copra offered for sale by natives, abomi-
nable rubbish exposed alternately to rain and sunshine,
until it becomes rotten. Ifthey do not put sand into it
like the Sinhalese, they often pour sea water on it in bulk,
which increases the weight without mildewing the copra.
It is a duty Government owe planters to see to this at once.
Again, if it pays better to make and sell oil here, why not
direct and assist coconut planters in this respect ? We see
in the above, that in Ceylon there are over 2,000 oil mills,
big and little ; in Fiji, not one!
A big mill in Suva or Levuka would raise the price of copra
immensely, and the honest planter would get a fair price
for his produce.

“Again we want very badly, small hand machines for
pulping and hulling coffee, For many years I have pre-
pared coffee from a small plot of about 100 trees. Lately,
with the help of a dozen Fijians, mostly children, I collected
a big sack full, slowly pulped it, as formerly described,
washed and dried it, and turned out avery good sample,
1 got Ist prize for some Liberian coffee at the recent Show
in Suva; but it does not pay, and about half the crop I
left on the trees torot. These are a few of the many things
in which Government could assist us planters. Some day
perhaps the Planters’ Association and the Agricultural
Board may wake up and attend to something besides bana-
nas, the culture of which is confined to the neighbourhood
of Suva, Rewa, Navua and Nadi.”
COCONUTS IN CEYLON.
The following is from the first annual report
of the Lowcountry Products Association of
Ceylon :—
Kstimated acreage in the lowcountry within
the scope of this Association :—

Total .- 837,000 R381,7C0,000
Your Committee venture to state that the
total capitalised aggregate value of the products
mentioned above (apart from the value of area
under paddy) is greater than the capital value
of area under tea, rubber, cocoa, which can
claim a total planted area of 660,000 acres,
In comparing the relative value of the coco-
nut industry or products of the coconut palm a
very materid4l fact requires special comment,
viz., the very large proportion of the products
which is utilised in the Colony itself for edible
purposes and in the form of oil for cooking and
lighting in plumbago mines and poonac for cattle.
The amount utilised in this manner may easily
be represented as the yield of not less than one-
third the area under cultivation in an average
year and the value of this is not shownand can-
not be in the export trade ofthe island. Apart
from value itis important to realise the benefit
which this industry confers on the dietary of the
population. It is a well-known fact and one that
has been insisted upon year after year by the
Registrar-General in his reports on vital sta-
tistics of the Island that the death-rate of the
Negombo and Chilaw districts is the lowest in
the Island, in spite of malaria. The liberal use
of the coconut as part of the food of the people
in those districts, and the steady high wage
which they command through the industry, are
undoubtedly responsible for the happy result
indicated in the vital statistics.
CULTIVATION OF THE Coconut PALM.
It is regrettable that the rainfall during the
year was adverse to the coconut planters in more
ways than one. The prolonged drought affected
the trees to a great extent. In the Puttalam and
northern section of Katugampola Hatpattu a
few hundred trees on estate plantations were
killed. In and around Chilaw several hundred
trees were seriously affected. The absence of
rain rendered manuring either inexpedient or
impossible which will result in a further shor-
tage of crops. The prolonged drought and the
failure of both monsoons affected new clearing
work and young plantations very adversely.
306
In addition to this the outbreak of malaria
during the last two months of the year rendered
nearly 90 per cent. of the estate labourers unfit
for work weeks together, in the Kurunegala,
Chilaw. and Negombo districts.
In the more progressive districts it is a grati-
fying feature that the application of artificial
manure and the systematic cultivation of land
is being carried on more and more as the ad-
vantages resulting become manifest. During the
jast two years experiments with the growing of
crotalaria having proved useful a very large ex-
gent of land is now under this for green manure.
MR. J. B. CARRUTHERS.
IMPRESSIONS OF CHANGES IN CEYLON.
In an interview an Observer representa-
tive had with Mr. J. B. CArrutuers, Director
of Agriculture in the Malay States, who is now
gomg home to represent the Malay States at the
Darwin Centenary at Cambridge, and later will
proceed to Trinidad, to be Assistant Director
of Agriculture, the first question asked had
reference to the changes which had_ struck
Carruthers in Ceylon since his !ast visit.
iy, CARRUTHERS—Said that when he was last
hero they were only just beginning to think
that rubber was a future possibility. Now it was
ait absolutely ascertained certainty. The rub-
ber industry was on quite a different footing
and it was only now a question of:solving the
problem of the most profitable ways of cultiva-
ting it. That had affected tea and the whole
thing seemed rather more prosperous, ‘The tea
industry was itself more prosperous and every-
thing seemed more prosperous in the planting
line. He had not really seen very much of
Ceylon. He went up. to the Gangaroowa Ex-
periment Station. That was beginning to
add to knowledge and it was getting into
shape, and becoming a useful sort of Tex Book
for Tropical Agriculture.
THe NorktHway SYSTEM.
The patent thing of Northway’s interested
him, Without having paid his 200 dollars
he seems to have found out the main principles
of the thing and it seemed to him very hkely
to be, not revolutionary, buta very sound ad-
dition to their experimental knowledge on the
question of the extraction of rubber.
What changes did you notice at Peradeniya,
Mr Carruthers ?
I donotreally know. The changes are for
the better. The building done is a great im-
provement, Their housing is a great advance.
They were cribbed, and cabined, and confined
in httle laboratories and now they have fine
places to work in. The Gangaroowa laboratory
has been built since [ was there. The gardens
seem to be just as beautiful as ever or rather
more so. Alltraces of the Rubber exhibition
seem to have beenswept away. (Laughing.) It
is about three yearsand nine months since I
was here last. I passed through in May.
Were you present at the Experiment Stations
Committee meeting ?
The Supplement to the Tropical Agriculturist
No. I just waited to meet all the members all
of whom were friends of mine but I didn’t stay
to the discussion. I heard of everything they
were going to talk about. Thegreen manuring
question was one of the chief matters. Some
of the plots are most interesting, nearly every
plant that can be conceived to be useful is to be
seen there. Then they have been working at
tlfése extraction questions, oils from grass,
citronella oils and other oils, the most profit-
able grass and all that sort of thing. The most
interesting thing about the station is that it
was about 7 or 8 years ago 90 per cent. diseased
with cocoa canker and if it had been in ordi-
nary hands it would have been abandoned, but
there is now about 2 per cent. of canker and the
place is giving handsome and profitable crops.
It can always be quoted as a fine instance of what
scientific tackling of a disease will do. It has
justified its existence if only for that and it has
added to knowledge in many other directions.
In answer to a final enquiry Mr Carruthers
said that the total acreage under rubber now
inthe Malay States was 240,000acres. 60,000 were
planted last year as against some 55,000 the year
before. There were 37,000,000 trees in the Penin-
sula, There were 112.000 acres of coconuts.
COCGNUTS IN B. E. AFRICA.
The value of the coconut plantations on the
coast, says areport from British East Africa,
has depreciated, owing to the damage caused by
beetles and to the custom which prevails among ~
the natives of tapping the flowers, from which
they obtain “tembo,” a native intoxicating
beverage which is largely consumed. The Gov-
ernment entomologist is investigating the life
history of the beetle with a view to devising
means for its extermination. There has latterly
been a distinct movement to revive the coconut
industry on the coast, wherein past years it
proved a large source of income to the Arabs
before they lost the services of a number of their
slaves.—Trade Journat.

age” isour old friend arrack. It only shows

THE COCONUT OIL MILL IN
KUALA SELANGOR.
The one and only sight at Kuala Selangor is
the Oil Mill on the opposite side of the river.
Visitors embark in a sampan from a shelving
stone jetty, if it can be socalled, which might
be vastly improved. At low water the embark-
ing ina sampan is an acrobatic feet. The Oil
Mill is well worth a visit. The first process is
to convert the nut into copra by means of
dryers, the copra is then passed through various
machines which grind it toa small powder.
This powder is then placed in fold over canvas
covers—about half a kerosine oil tin going to
one cover—and then placed in the hydraulic
press. This press takes quite a number of these
canvas bundles in its different compartments,
and Magazine of the Ceylon Agricultural Society.
The oil is then squeezed out into a bank below
from which itis sucked up to pass through a

The place is full of all scrts of machinery and
another huge boiler has just been erected to
enable the company to keep the Mill going
without the otherwise necessary stops for boiler
cleaning. Coir making machinery has recently
been erected, so that every part of the coconut
can be used except the milk, Now that the
company has its own steamer there is no diffi—
culty in getting a full supply of nuts. The com-

SANDY SOILS AND THEIR
IMPROVEMENT.
—_——_—
The improvement of sandy soils is a subject
of wide interest, and any mgans that would tend
towards effecting such improvement will be wel-
comed as much in this island as elsewhere, since
there are large areas of land that are charac-
terised by soils composed chiefly of silica, Acom-
mon objection to most soils.is the disproportion-
ate preponderance of one ingredient over the rest,
whether sand, clay orhumus, The moans of im-
proving soils must, of necessity, differ, inasmuch
as the preponderating ingredient invests a soil
with properties that have to be specially reck-
oned with. Thus the treatment of a heavy clay
will materially differ from that ofa loose sand and
of both from that of a soil made up almost en-
tirely of organic matter. The New Jersey Ex-
periment Station recently published an account
of experiments made to improve sandy soils,
and a consideration of the results should be pro-
titable to all who have similar problems to face,
A fact that has to be recognised at the
outset is that sandy svils are, from their
very nature, unable to furnish as much plant
food or moisture to growing crops as those of
a clayey nature : further, that the coarseness of
sandy soils prevents them from retaining either
food or water when given to them, All who
have had anything to do with sandy soils will
readily admit that manures are easily washed
downwards into the sub-soi] by rains, while dry
weather soon robs them of moisture.
for successful cultivation, such soil needs a
tolerably well-distributed rainfall, a fairly com-
pact sub-soil, and a water-table near enough to
the surface for cultivated plants to draw upon
the moisture below. In very coarse soils of
this nature, capillary power is so limited that
they are unable to replenish from below the
loss of moisture by evaporation. Again, the
openness of light sandy soils, by admitting air
freely, accelerates the chemical and bacterio-
logical changes going on within them, so that
plant food is made more quickly available;
pometimes, indeed, too quickly—so that organic
Indeed,
307
matter in the soil becomes exhausted sooner
than is desirable, Well-aérated soils, there-
fore, favour bacterial activity, but the loss of
water from them interferes with the action of
soil organisms.
To improve sandy soils, tharefore, it is ne-
cessary to reduce their too open texture :—
(1) by methods of tillage, such as cultivating
and rolling ;
(2) by application of fine-grained materials
or substances readily pulverised, such as clay
or loam ;
(3) by the addition of large quantities of
humus-forming material, such as green crops or
‘* long ” manure,
A sufficiency of humus prevents too ready
access of air and increases the moisture-holding
capacity of a soil. Although sandy soils are
naturally poor in plant food, this does not pre-
vent the possibility of their improvement. Phos-
phoric acid and potash can be supplied at a
comparatively small cost, and nitrogen pro-
vided by means of green manures or animal
manures. The last-mentioned are not indispen-
sable and often too expensive ;in some cases
they are the means of introducing weeds or
fungus diseases. Green manuring is particularly
effective on account of the relatively groater
need for nitrogen and humus in light soils, and
the facility with which green crops are converted
into available plant food. The selection of these
will depend pvreatly on local conditions, the
number to select from being fortunately large.
A mistake that is common is to expect
green crops to flourish even though there
is an entire absence of phosphoric acid,
potash and lime in the soil. That is not rea-
sonable, and where these ingredients are de-
ficient, the deficiency must be made good. If
this is done, and thereis a fair rainfall, the
prospects of utilising green manuresin the way
suggested, are good. With the supplying of
humus to a sandy soil, and the increase of its
water-holding capacity, a uniform bacterial
development and a more uniform supply of
available plant food will be assured ; indeed, the .
growth of bacteria is directly encouraged in the
presence of organic matter and moisture,
The nitrogen-fixing bacteria of lezuminous
plants find very favourable conditions in sandy
soils, and that for the following reasons :—
(a) The small proportion of available nitro-
gen in them.
(6) The free circulation of air which favours
the formation of nodules,
(c) The frequent renewal of air which enables
the bacteria to supply themselves with the ele-
ments of the atmosphere.
It has been found that in compact soils,
nodules on roots are limited and found near the
surface, whereas in sandy soils they are well
distributed and occur at greater depths,
There is an impression abroal that a leguini-
nous crop which succeeds in one place is bound
to succeed in . another, which is not so, auda
crop new to a given locality may entirely fail to
develop nodules because the proper organisiag
308
are not present inthe soil. The bacteria-pro-
ducing nodules in different crops (say, soy bean
and cow pea) are not identical, and each legu--
minous plant may be said to haveits own
organism. The importation of earth from a field
where a nitrogen-ygatherer flourishes generally
suflices to start the formation of nodules on the
roots.
Lime, while not required to any extent by
sandy soils, pats te the formation of humus,
which helps to fix phosphoric acid and potash,
Lime, therefore, though necessary,. should be
only sparingly given—so that it may not unduly
encourage the development of soil bacteria
which hasten decomposition of organic matter.
Ground unburnt lime is to be preferred to burnt
and slaked lime. A dressing of half-a-ton of
round oyster shells will generally be found suf-
ficient ona sandy soil. Lime, asis well-known,
is appreciated by most leguminous crops.
In the New Jersey experiment the land (a
distinctly sandy soil), while under preparation,
was given 1,000 lb. lime, 320 lb. acid phosphate,
100 lb. ground bone, 160 1b. muriate of potash,
150 lb. of dried blood per acre. The returns
showed a gradual and marked increase, and it
is considered reasonable to assume that by sys-
tematic cropping and fertilising, uncultivated
and unproductive lands may be profitably uti-
lised, particularly for the production of fodder
crops with which dairy-farming might be profit-
ably associated.
It would, indeed, appear that sandy soils have
a great future before them and that some day
they are destined to be the scene of intelligent
and remunerative cultivation.

Aden, Jan. 23.—I have just had an interview
with Mr. Stewart J. McCall, on the deck of the
steamer ‘‘ Kronprinz,”’ as he was about to leave
Aden yesterday, en route for Nyassaland, where
he takes over the duties of Director of Agricul-
.ture. There are few men who have had such a
varied experience in cotton-growing as Mr.
McCall, and his name will be well remembered
by many officials of the Federal Department in
Washington and also in the cotton-growing
States of America, through which he passed on
a professional tour last summer. Prior to his
arrival at Aden, Mr. McCall had passed three
months in Ceylon, anverliaane the prospects
for cotton-growing in that island, and at the re-
quest of the Government wrote up an extensive
report on the subject, which is to be published.
Harty EXPERIMENTS.
He informed me that attempts to grow cotton
in Ceylon in small quantities had been made for
many years; but they had not been wholly suc-
cessiul, owing to the fact that the most tavour-
able seasons for planting had not been observed,
and other essentials with regard to local con-
ditions had been omitted. He considered the
prospects for cotton-growing in Ceylon decidedly
good, but it was necessary to plant in the dry
season with adequate and regulated irrigation,
The Supplement to the Tropical Agriculturist
He said the most favourable land was situated
in the northern provinces, where nearly four
million acres were available and suitable for this
purpose, under irrigation. At present, prac-
tically nothing is being done with the land in
question, so that the suggested schemes, if
carried into effect, would not in any way inter-
fere with the present products of Ceylon. ‘
“What are the prospects of a commercial
success being attained?” I inquired.
‘¢ These are in every way excellent,” Mr Mce-
Call replied, ‘‘as transport is cheap to and from
Colombo, beside which a good Government
railway penetrates the suggested provinces.
Naturally, considerable care would initially
have to be taken as regards the variety of cotton
introduced, and I consider that which has proved
the greatest sucess in Egypt is most suitable,
samples of which sent to Manchester as far back
as 1905 were valued at ninepence a pound, being
well up tothe average of Egyptian cotton for
that year. Experiments have been conducted
throughout the three intervening years, and
there is now a considerable quantity of cotton-
seed of this particular type available, partly
acclimatised, at the Government experimental
station in Ceylon.”
MARGIN OF PROFIT.
‘“* The matter is under the consideration of the
British Cotton Growers’ Association at Man-
chester, besides attracting the attention of local
planters. Tho cost of production should net
average more than sixpence a pound, so that the -
margin of profit is a good one.”
The fact that Mr McCall previously held the
appointment of Lecturer on Agriculture at the
Agricultural College in Cairo, Egpyt, places him
in aposition to speak authoritatively on Egyp-
tian cotton.—New York Herald, Feb. 7.

HOW TO GET RID OF ‘“‘ILLUK”’
GRASS ?
Batticaloa, March Ist.
Drar Siz,—In your paper recently { notice
a correspendent writing about the destruction
of illuk grass on Mr. Nicholas’s estates. Would
you be so kind as to get the information from
Mr. Nicholas or your correspondent how to get
rid of the illuk, as we have a great quantity
here aud would like to know how it is destroyed ?
—Yours faithfully,
JUHN COTTON.
Mr. G. T. Nicaouas’s METHODS.
Golua Pokuna, Katunayaka, March 10th.
Dear Sir,—Absence from home has delayed
my responding to the call made on me, in your
issue of the 4th instant, in reference to Mr. John
Cotton’s letter, asking for information as to how
to get rid of Illuk grass.
Just three years ago (5th March, 1906), the
Hon. Mr. J. Ferguson, c.M.G., read a paper, at
the meeting of the Board of Agriculture, on
‘‘Tiluk or Lalang Grass: a tropical weed pest,
with measures for combating it,’’ supplemen-
ting his paper with one by myself ‘‘Ona Simple
and Inexpensive Method of Suppressing and
Exterminating Illuk over large areas in Coconut
Plantations.” These, with other connected papers,
were published in full in the May 1906 number
The Supplement to the Tropical A griculturist .
ofthe “Tropical Agriculturist” and I refer Mr.
Cotton tothe magazine for full details of my
methods and results.
The idea of growing certain plants to keep
down Illuk Grass appears to have ‘‘ caught on”
for we now read of /'assiflora fetida being used
in the Malay States for suppressing the pest.
But, in my opinion, this plant is less suitable
than the Madu vel (Sinh.) which is of a more
robust habit of growth; if the latter be grown
along with the shrub known to the Sinhalese
as Pupulu, the Illuk issoon got under,
The tendrils of the Madu vine attach them-
selves to the blades of [lluk and draw them
down, whilethe thick close growth of the Pupula
shrub completely shades the ground and helps
to choke out tho weed grass.
I shall be glad to give Mr. Cotton any further
information on this subject and also to send him
seeds of the above-mentioned plants, 1f he will
communicate direct with me,
Treatment with ‘‘ Arsenite of Soda” is said
to have proved very successful in experiments
made in Selangor, but [ have never tried it as [
have been quite satisfied with the efficacy of my
, own method which is devoid of any element of
danger. ‘‘Arsenite of Soda” being very poisonous,
care must be taken that no cattle eat the treated
grass.
The method of preparation and application
of the solution is as follows :—‘‘2°88 lb. of
washing soda are dissolved in 3 gallons of water
and boiled; then 2 lb of white arsenic are
slowly stirred in, the liquid being kept boiling
till all the arsenic is dissolved. It is then
diluted to 20 gallons as a stock solution,”
‘Two pints of this are diluted with five gallons
of water and this is sprayed on the grass, or it
can be put on by means ofa cloth, one end of
which dips in a trough on wheels containing the
solution, the other trailing on the grass and kept
open by means of an iron rod.”
‘‘The grass can be first burned off. When
new shoots are 8” to 9” long the wet cloth is
drawn over them which kills the shoots in 48
hours. This is repeated each time new shoots
appear, the object being to exhaust the roots of
all starchy matters and so kill the plants en-
tirely.’’— Yours faithfully,
GERALD T. NICHOLAS.

CLosE PLANTING oF RuspBER.—With regard to
distance in planting it is of interest tu record
that on Caledonia Kstate 378 lb. of dry rubber
per acre was obtained in one year from seven
year old trees, planted 10 feet by 10 feet.-W J

RUBBER GROWING IN THE SEYCHELLEs.—A
correspondent in Seychelles informs us that
Para rubber is thriving exceedingly well in that
part of the world, but that Funtumia, Castilloa
and Ficus are by no means proving successful.
It appears that Funtumia and Castilloa in Sey-
chelles suffer very much from parasites, especi-
ally scale insects. —India-Rubber Journal, Jan,25.

ANTHURIUM VEITCHII.
This is one of the finest and rarest of Anthuriums.
{It bears large ovate-oblong leaves, which when young
have a striking, glossy metallic appearance. A distin-
guishing characteristic of the plant is the curiously
waved surfaces of the leaves, which is imparted by
the sunk and arched veins. The plant is «a native
of Colombia, where it was first discovered in 1877. Being
of slow growth, and difficult to propagate, it is rarely
seen in living collections.

A revised list of the Plots on the Experiment
‘Station, Peradeniya, by R. H. Lock: Circulars
and Agricultural Journal of the Royal Botanic
Gardens, Ceylon, Vol. IV., No. 18.
The writer of this note does not pro-
pose to criticise his own publication.
The appearance of this circular, which
consists almost exclusively of a compila-
tion from the work of others, is merely
taken as the text for a few remarks on
the history and position, functions and
work of this agricultural institution.
The writer, however, feels justified in
remarking that he has had rather special
opportunities of becoming acquainted
with his subject, having had facilities
for closely examining the whole estate
during the two first years of its occupa-
tion by the Ceylon Government; whilst
during the past year he has had the
advantage of revisiting it after a con-
siderable interval and noting the marked
improvements and extensions of work
which have been carried out.
The historic estate of Gangaruwa, first
opened in coffee by Sir Edward Barnes,
and more recently cultivated in cacao,
coconuts and other products, was taken
over by the Government of Ceylon on
May Ist, 1902, in order to be developed
as an experimental plantation for the
suited to describe the position and func-
tions of this institution. To this ques-
tion of a name we venture to direct
Special attention, because it is one upon
which there exists some misapprehension
and the station is often miscalled, both
in the press and in conversation.
At the outset practically the whole
attention of the small staff had to be
devoted to a single large experiment,
which occupied the greater part of the
cultivated area for some years, and can
be said to have only recently been com-
pleted. In 1902, the Cacao canker, then
rampant in many parts of Ceylon, had
thoroughly established itself on Ganga-
ruwa estate, so that practically all the
cacao trees over 150 acres were affected
by this scourge, and the crop had sunk
toa figure which represented a dead loss
to the estate.
Vigorous measures were immediately
undertaken, an account of which is to
be found in the Reports of the Controller
of the Experiment Station and of the
Government Mycologist for 1902 and
the years immediately following. As
the direct result of these measures the
cacao canker may now be said to be
under complete control, whilst the con-
dition and cropping power of the plots
under experiment may be said to be as
314
good as they could possibly be—if the
nature of the varieties and the way
they were originally planted are taken
into consideration. It may safely be
asserted that this first large experiment
has turned out an unqualified success,
and that the instruction afforded by it
has not been without value to the cacao
industry of Ceylon.
We may next allude to the important
series of experiments relating to the
manuring of old cacao, and representing
the first thorough investigation of the
effect of the repeated application of
various fertilisers to a permanent crop
in the tropics. It is too early, as yet,
to dogmatize upon the 1esult of these
experiments, but from their very nature
it is impossible that they should ulti-
mately tail to yield information of
first-rate value. The celebrated experi-
ments at Rothamsted have now been
in existence for over sixty years, and
although they deal with the manuring of
an annual crop, some of the original
trials are still being continued. There
is, no doubt, that such experiments
must be continued over a considerable
series of years before the conclusions
drawn from them can be_ regarded
as beyond the reach of criticism.
It is therefore useless to be impatient of
results, and worse than useless to jump
to hasty conclusions from the result of
afew years’ work; but itis anticipated
that in another five years or so we shall]
begin to know something about the
manuring of old cacao. Meanwhile, a
long series of minor experiments have
been carried out, and these alone would
be sufficient amply to justify the exis-
tence of the Experiment Station during
the first few years of its being. EHxperi-
ments have been made, or are being made,
upon the following products among
others—attended in every case with
information of value to those interested
in them—Cacao, Tea, Rubber (including
Hevea, Castilloa, Funtumia, Ceara and
the new varieties of Manic¢obar), Coco-
nuts, Paddy, Arecanuts, Citronella and
Lemon grasses, Tobacco, Maize and
various leguminous plants, as wellas a
number of others of lesser interest.
Criticisms have reached us at various
times because some of our experiments
have turned out to be failures. To criti-
cise an experiment and say it ought
uever to have been attempted because it
has not turned outa success, shows not
only a want of appreciation of the essen-
tial natuce of an experiment, but also
a misapprehension of the chief aim
and object of an Experiment Station.
We conceive it to be one of the chief
functions of those responsible for the
working of such a station to make
[ApRin, 1909,
mistakes in order that others may avoid -
them. Itis their business to try forms
of cultivation so speculative that people
of moderate capital are not justified in
attempting them for themselves. Such
forms of cultivation will often turn out
to be impracticable, but even if one out
of many proves to be a success, the infor-
mation gained will make up for many
failures by its value to the community
at large. An allied, but more serious,
mistake into which visitors have some-
times fallen is to suppose that because
some particular crop is being tried upon
the Experiment Station, it is thereby
guaranteed asa paying form of culti-
vation, A reference to our preceding
remarks will show the reason why this is
not by any means the case. Reports on
all such crops are published in due
course, and it is by these that we expect
the public to be guided. On the other
hand, visitors who have eyes to see, and
who are able to refrain from jumping to
conclusious upon a cursory examination
of incomplete experiments, will find a
great deal to interest them on the
Experiment Station—whatever their own
particular line of agriculture may be—
and all such visitors are very welcome.

CAMPHOR OIL.
Camphor Oil and Camphor : Schimmel’®
semi-annual report, November, 1908,
shows that owing to the weak market
stocks have largely increased in Japan
and prices are likely to go still lower.
The price of refined camphor has drop-
ped in Japan to 1s. 53d. per Ib., with
the alleged object of killing the com-
petition of synthetic camphor which has
partially succeeded, as it is said that the
principal makers in Germany have for
the present ceased manufacturing. If
true there is no reason for a further
decline in the price cf camphor.
The chief countries using camphor are
British India and the Straits Settle-
ments, where the consumption is chiefly
due to the use of camphor in the manu-
facture of fumigating candles for ritual-
istic purposes and of medicinal prepar-
ations; Hurope and America, where it
is mainly employed in the manufacture
of celluloid, ;
The Japanese Government intends
monopolising the trade in camphor seed
and may stop exportation of seed al-

together, seedsmen having already been
cautioned against selling large quantities
of camphor seed abroad,
The decline in pricesis said to be main-
ly due to the increased production of
Natural Camphor in China, and of Syn-
thetic Camphor in Germany, also of
‘“*Monol” and other substitutes. In the
South of China camphor trees are abun-
dant almost everywhere and the ex-
port is rapidly increasing. The Chinese
Camphor is not as pure as the Japanese,
owing to cruder methods of distillation.
In Formosa the camphor production
was limited to the Western, Northern
and Southern parts of the Island, the
regions inhabited by the Aborigines
having scarcely been touched.
Recently a Government expert dis-
eovered a forest rich in camphor to the
South of Arisan, and a favourable deve-
lopment of the Formosan Camphor in-
dustry is anticipated from this fact.
The Japanese have commenced the
cultivation of camphor in the Korean
Island, Quelpart, and intend introducing
there either the Borneo Camphor tree, or
the rapidly-growing composite Blumea
balsamifera.
Successful experiments in the culti-
vation of camphor have recently been
made in parts of Upper Burma, close to
the China Province of Yunnan. ‘The
Government of Assam have also made
successful cultivation experiments in
the plant of Watijain.
Numerous enquiries have now been
made to this Department for the best
methods of distillation of camphor from
the leaves, and it is evident that the
areas planted in India, Malay States, &c.,
are now coming into bearing.
A paper by Giglioli, “Le Camfora
Italiana, Rome, 1998,” has now appeared
in print, and is said tosupply detailed in-
formation on the production and the price
fluctuation of Synthetic Camphor; the
presence, production and commercial con-
ditions of the Natural product; botan-
ical, geographical and_ climatological
notes on the camphor tree; production
and purification of camphor and the state
of the trade and prices of camphor cil.
He recommends the cultivation in every
part of Italy except the interior, and the
cooler northern provinces ; and drought
and inclement winds must be avoided.
The average camphor content in fresh
leaves grown in Italy is given as from
1:2 to 1°38 per cent. and about 0'5 per cent.
of oil. The average yield obtained by
distilling by the Japanese method is 1
per cent. of pure camphor.

Journal d’Agriculture tropicale 8 (1908)

129 is sceptical about the cultivation of
camphor and distilling the leaves, and
does not think itcan compete with cam-
phor from the natural forests of old trees
or with the synthetic camphor now being
put on the market—a new factory for
which is being established in Finland
to develop a new process of Komppa.
Cinnamon Oil, Ceylon.—The chemical
properties are given of Ceylon Cinnamon
oil as bright yellow, feeble acid re-
action : dois 1024 to 1040 aa, slightly to
the Jeft. Soluble in every proportion of
.90 per cent. alcohol: test for nitric acid ;
Aldehyde content 65 to 75 per cent.
(determined with Sodium bisulphate).
Lemon Grass Oil.--The price of this
oil fell from 9d. per oz. in 1905-06 to
2d. in 1908, owing to large imports
from West Indies accumulating in Lon-
don; but these are now to a great
extent cleared and such large supplies
are not liable to be repeated so quickly
in future.
The oil content of the individual parts
of Andropogon citratus have been
investigated by A. W. K. de Jong, who
found that the leaves contained most of
the oil, the largest quantity being in the
latest formed leaf, decreasing as the
leaf ages.
The citrate content of the oil becomes
slightly higher as the age of the leaf
increases, viz., from 77 to 79 per cent.
in the youngest to 83 per cent. in the
oldest leaves. The sheathsalso contain
oilbut less than the leaves themselves.
The thick bulbous roots also contain
from 0°5 to 0°35 per cent. of oil according
to the age and their distillation is sug-
gested, but the quality and citrate con-
tent is not given.
De Jong concludes that the plants
should be cut when four or five leaves
only have formed.
In Cochin-China distillation experi-
ments have been made which show that
the grass contains much more oil in the
dry than rainy season, and that the tip of
the leaf to one-third of its length js more
aromatic than the remaining two-thirds.
Dried leaves, losing 70 per cent. of
moisture, yielded 8 to 8°5 per cent. of
oil, whilst fresh leaves yielded in the
rainy season 2 per cent, and in the dry
5°b per cent.

THE KLEMENTS OF PHILIPPINE
AGRICULTURE.
By E. B. CoPpELAND.*
This is one of the first serious attempts
to write an elementary text-book of
Agriculture for use in tropical schools,
and consequently requires serious con-
sideration.
The author recommends that the work
be used in connection with a_ school
garden, in which every boy should have
a plot about 15 feet by 9, if necessary,
rather than make the plots smaller; he
would put two boys to each, as with
small plots the importance of space is
not properly understood, The student
should map his plot carefully ; this, of
course, is incidentally useful as a lesson
in geography. His plants must be most
carefully laid out in regular rows at
exact intervals. Each student should
keep a note-book in which the map is
entered, and every detail about the
growth and treatment of the plants, and
these should be frequently overhauled
by the teacher.
After a general introductiou the book
goes on to deal with the parts of plants,
with the soil, with plants and their need

of light, water, &c. Though somewhat
too condensed, this part should be easily
enough understood by a boy of say 15,
and to younger children than this we
would not teach agriculture.
After this follow chavters on the
actual crops, maize, coffee, abaca, &c.
It is difficult to criticise an elementary
pioneer work like this; but, in general
our impression isthat, while a good work
so far as it goes, itis too much con-
densed, and will require great ampli-
fication, with detailed practical demon-
stration, by a good teacher; and itis in
the provision of such teachers that the
difficulty lies in tropical agriculture.

A STORY OF GROWTH.
At the beginning of a new year in the
life of The India Rubber World it
always has seemed to us appropriate to
engage somewhat in retrospect. The
recounting of accomplished progress
in any industry is of interest not only
in itself, but as indicating lines of
possible future development. The nine-
te en years which have elapsed since the
initial issue of this journal have been
fruitful in invention and progress in
many ways, and in to other industry,
perhaps, more than in rubbder and the
allied interests. We feel certain that
the last word has not been said in the
development of rubber interests, and
look ‘forward to chronicling every year
much more news of importance in this
trade.
To eliminate from the rubber trade
to-day all that has been developed in
it within the past nineteen years would
leave some very wide gaps—nearly
everything in the way of vehicle tyres,
the greater part of the insulated wire
manufacture, air-break hose, hose for
pneumatic tool work, the rubber-cored
golf-ball, and an immense number and
variety of minor articles of rubber,
together with the new processes and
apparatus which have been perfected
for their production.
The rubber world, so to speak, has
been greatly broadened in those nine-
teen years. The opening up of forest
rubber areas in Africa and in the upper
Amazon regions has alone proved of
vast importance tothe industry, while
the iatroduction of rubber culture has
still further increased the world’s
supply of raw material. Scarcely less
important has been the great improve-
ment in reclaiming rubber and the
increase in the volume of this product.
The growth in the extent of the output
of the rubber factory has involved not
only a large increase in consumption at
home, but the sale of important quanti-
ties in countries not consumers of rub-
ber before.
We cannot better sum up the stitu-
ation, perhaps, than by referring to the
International Rubber and Allied Trades
Exhibition, just closed in London, as
an epitome of progress in rubber; to
have omitted from its catalogue all that
represented development during the
past two decades would have left little
more than a skeleton. We regard this
exhibition as epoch-making, and by
comparing few rubber exhibitions with
it will best be measured the growth of
the trade.
It is of interest to note that seldom
has rubber been utilized to an impor-
tant extent for the purpose without con-
tinuing to be so utilized. Hence every
new application means a permanent
addition to the catalogue of the uses of
rubber. To-day the possibility appears
to exist of a great coming demand for
rubber in aerial navigation—a demand
which within the coming nineteen years
may prove as important as the present
demand for rubber in the tyre trade.
We donot doubt that the most im-
portant development in the next decade
will relate to the production of crude
rubber—in new fields and from new
plants, as well asin the improved pre-
paration of rubber in the field now ex-
ploited. It isnot unlikely that within
this period the culture of what now are
regarded as minor rubber plants will
become extensive in the temperate
zone.—The India Rubber World, Vol.
XXXIX., No.1, October, 1908.
THE RUBBER EXHIBITION : SOME
NOTABLE EXHIBITS AND MR.
BAMBER’S PROCESSES.
By Huspert L. TERRY.
The main features of this Inter-
national Rubber Exhibition have been
dealt with by the Editor, and the obser-
vations I am about to make refer
entirely to the raw_rubber exhibits
of Ceylon and British Malaya, which
occupy two of the most prominent
stands in the Hall. Stand is perhaps too
plebean a term to use in connection with
the ornate pavilion of Ceylon and the
attractive native dwelling of Malaya,
but its significance will not be misunder-
stood. These two exhibits, along with
the Dutch colonial exhibits, may, I
think, be selected from the bulk of the
show as of special, interest, embodying
as they do the results up to date of the
rubber planting industry—one of,the
uewest departures in economic botany.
In no way do I wish to belittle the
interest attaching to exhibits of raw
rubber from the forest—such as the
splendid show made by the State of
Amazonas. Native rubber, however, is
not exactly a novelty, and as the object
of the exhibition was declared by the
President in his opening speech to be
primarily educational, it is important to
Gums, Resins,
lay stress of the greatest novelties in so
far as they have an important bearing
upon the rubber interest generally.
Both the Ceylon and the British
Malaya stands contained samples of
plantation rubber from the most import-
ant of the numerous companies located
in their respective districts, and it would
probably prove more monotonous than
instructive to refer to each of these
separately, especially as the rubber in
its various forms of sheet, block, crepe,
worm, etc., is much the same as produced
by each company. Botanical exhibits
were numerous, and also photographs of
general scenery and processes connected
with the industry. Samples of such
catch crops as indigo and tapioca were
also to be seen, and mention should not
be omitted of the model estate rubber
factory at the Ceylon stand fitted up
according to Mr. Kelway Bamber’s ideas
of how the work of preparing | raw
rubber for the HKuropean market should
be carried out. It is, of course, noto-
rious that the procedure on different
estates varies considerably, which is not
surprising, seeing the novelty of the
whole busiuvess, and no doubt for some
time to come we shall witness great
divergencies of opinion,
There is no doubt, however, that
the planters will best serve their own
interests if they endeavour to produce
rubber of always the same quality, even
of the same tint. This latter point may
not really be of any importance, but it
carries weight with the less enlightened
manufacturer. The great complaint in
manufacturing circles up to now has
been about the want of uniformity in
bulk lots of plantation rubber, and
this is of course due to the different
procedure adopted on the various
estates, and also to the variable pro-
cedure of any particular estate. In this
respect, therefore, I consider that the
detailed proposals made by Mr. Kelway
Bamber for the coagulation and pre-
paration of the rubber on exact and
uniform lines form one of the most
important topics brought to the notice
of visitors to the exhibition. The varia-
tion in the colour of the plantation Para
from Ceylon and Malaya as shown in the
numerous specimens on the stands is
very striking, practically all shade from
pure white through yellows and browns
to black being represented. If Mr,
Bamber’s process is generally adopted in
the future, it will mean thata uniform
product which is practically white will
be produced, and that rubber manufac-
turers will be able to order lots amount-
ing to several tons with full confidence
that the quality will be the same
throughout. It would take up too much
318
, [Apriz, 1909,
space to give Mr. Bamber’s proposals in
anything like detail, but a summary of
the main points may be attempted.
It is important to make a daily testing
of the latex from each field in order
to determine when the proportion of
rubber has fallen to the minimum paying
quantity.
Whatever method of tapping is
employed, the trees should be marked
in such a way that the bark will be
removed systematically and no irregular
patches left which cannot be tapped.
The best angle is 45°, and this should be
maintained by keeping the cuts perfectly
parallel from start to finish, and not
gradually making them more vertical
towards the lower end.
The knife must be kept perfectly sharp
so as tocut and not tear the bark, and
immediately after making the cut the
channel should be moistened with a very
dilute ammonia or formalin solution
applied by means of a piece of cloth on
a stick; this encourages the flow, delay-
ing the coagulation, and the proportion
of scrap rubber is reduced.
Mr. Bamber advised the use of glass
or stoneware cups in preference to sheet
iron, as they are more readily cleaned.
They are also to be washed before use in
a dilute formalin solution made by
mixing one part of the ordinary 40 per
cent. solution of commerce with 40 parts
of water. All the latex collected in the
cups is to be strained through fine wire
gauze into enamelled or wooden buckets,
and on arrival at the factotyis again
strained into large vats and sampled for
its yield of rubber. With regard to the
determination of the amount of web
rubber per gallon, it may be remarked
that unless the exact procedure is de-
tailed, very variable results will be
obtained by different operators, a very
similar case being the approximate de-
termination of gluten in flour. With
regard to coagulation Mr. Bamber does
not seem to favour mechanical methods
except where the amount of latex to be
treated is only small. His proposals are
a high temperature and the use of well
diluted acetic acid.
Itis inthe coagulation that his most
important suggestions arise. He has
found that if the latex has steam passed
into ituntil the temperature arises to
180° F., and is maintained at this heat
for three hours, certain organic sub-
stances of a proteid nature are destroyed,
and the rubber subsequently precipitat-
ed by acetic acid is quite white and
maintains this colour after shipment.
It is mentioned that a solution of wood
creosote in spirit can be added during
coagulation if desired. Presumably the
Fo
Apri, 1909,]
doctors are not agreed as to the utility
or otherwise of this addition of creosote.
Samples of perfectly white rubber pre-
pared by this oxydase-destroying process
wereto be seen on both the Ceylon and
Malaya stands, and it will be interesting
to hear what the trade has to say about
them. Mr. Bamber’s main contention is
that uniformity in bulk will be secured,
and, further, that the colourless rubber
will be found of special use in the manu-
facture of certain goods—such as teats,
for example—the white colour not being
affected by the vulcanization.
With regard to the subsequent wash-
ing and rolling processes it is advised
after the first rolling to again immerse
the rubber sheetin water at 180° F. to
ensure complete destruction of the
oxydase and the complete removal of all
soluble matters on which bacteria and
fungi grow. After this the rubber is
allowed to contract naturally in cold
water out of contact with the air.
Mr. Bamber is against the too rapid
drying of the rubber, and remarks that
the 10to 15 per cent. of moisture in
Brazilian Para is probably an advantage
to it. Hedoes not seem to be enamoured
of the vacuum drying process, and thinks
that the vacuum process if used at all
should only come after the natural
drying in order to get the rubber quite
dry for packing. The best method in
his opinion is the use of perfectly dry
air which can be obtained easily and
economically by a plant of which a
working model was shown at the Ceylon
stand. It involves the use of a refri-
gerating plant and a system of pipes
which strike one as decidedly ingenious,
and for the purpose to be achieved to be

THE NEW MANIHOTS.
By Dr. C, E. WATERHOUSE.
During the last two years and es-
pecially this year great interest has been
aroused in some new species of Manihot
rubber trees which from all accounts are
far superior to Manihot glaziovii, and
which should be of special interest to the
rubber growers of Hawaii, from the fact
that the Manihot glaziovii or Ceara rub-
ber tree grows and yields so well in
Hawaii. Some of the reasons why, if
these species do as well as the Ceara, it
will be well worth the while of the rubber
growers of Hawaii to pay particular
attention to these species in future plant-
ings will be forthcoming later in this
paper,
319 Saps and EFxudations,
The export of rubber from the State of
Bahia has increased more than ten fold
within six years, having risen from
100 tons in 1900 of very inferior rubber
to over 1,100 tons in 1906 of a very
superior grade of rubber. This led to
an investigation of the sources of this
new supply and the discovery that, in-
stead of the low grade of Mangebeira as
formerly gathered, the suvply came
mainly from the three new and very
valuable varieties :—
1. Manihot dichotoma or Jequie Mani-
coba ;
2, Manihot heptaphylla or Sao Francis-
co Manicgoba ;
8. Manihot piauhyensis or Piauhy
Manicoba.
These varieties were so named by Dr.
Ule, so well known as an authority on
the classification of different srecies of
rubber trees, and who visited the State
of Bahia and neighbouring States in 1906
to look into the sources of this supply.
Until six years ago Manihot glaziovii
was considered the only rubber-yielding
species of its genus (though there were 82
species recorded which will soon be 100
when all those discovered are described).
It was only in the early part of 1906
that even the Kew Gardens, the birth-
place, so to speak, of the rubber industry
of the far East and always on the
lookout for new species of rubber, was
aware of the existence of rubber-
yielding trees closely related to the
comonly cultivated Manihot glaziovit.
All these species, from all accounts, not
only yield considerably more latex than
the Ceara, but what is of very much more
importance to Hawaii is, the amount
which one man can collect is much
greater (in other words the cost of
collection is considerably less). This isa
most important item here owing to the
high price paid for labour, in fact the
point upon which the whole success of
the rubber industry in Hawaii hinges.
A notable fact in this connection, one
which will appeal to any one who has
had any experience in tapping the Ceara
is thatin these new varieties, in shedding
the bark, longitudinal slits are formed
and the membranous bark peels off in
more or less verticle rows. This allows
its removal much more easily and there-
fore cheaply, than is the case with the
Ceara.
These varieties of Manihot, like the
Manihot glaziovui or Ceara, have a very
dry habitat, However, just as we find
here in Hawaii that the Ceara does
better in wet localities, so with these
varieties the same may be true, That
the Ceara does better here where it is
Gums, Resins,
wet I think there is no doubt. I have
myself ina little experiment station of
my own tried watering some plants and
leaving others in the same soil unwater-
ed, and the watered plants far out-
stripped those unwatered, and seemed
to have as much more latex, though
the trees are still too young to draw
conclusions from as to yield.
In regard to these three varieties:
(1) Manihot Dichotoma.
The seeds of this variety are much
larger than those of the Ceara. Germin-
ation takes place in two to three weeks
if unfiled, the shell being much softer
than in the case of the Ceara. The
soil upon which this tree flourishes
is variously described as red clay and
red loam. The bark of this tree is
thinner and more delicate than that of
the Ceara,
(2) and (8) Manihot Heptaphylla
and Manihot Piauhyensis.
The seeds of these two varieties can
hardly be distinguished from each
other; they are only a little larger than
Ceara seeds. They do not germinate
nearly as well as in the case of the
Manihot dichotoma. These two varie-
ties in the region around Bahia thrive
in a sandy soil, growing largely on
sandstone mountains. Both varieties
do not grow as tall and are smaller
than the Manihot dichotoma and in-
clined to branch low. They are not
affected by the wind so much as Ceara,
probably on account’ of being smaller
and more low lying. This also affects
the methods of tapping as explained
later. The foliage is cnaracteristically
green and fresh-looking.
Methods of Planting.—There are a
number of plantations around Bahia,
some of which are now three or four
years old. They are planted for the
most part 1,000 trees to the acre. This
close planting has been atopted because
the trees are planted in a dry locality,
and itis claimed that if not planted so
closely, or say 200 to the acre, the
ground would be baked so hard and dry
that the trees would dwindle and die.
Also the trees are considerably smaller
than other varieties, and consequently
need less room.
Methods of Tapping.—In the case of
the Manihot dichotoma the bark of the
trunk is tapped and an instrument curv-
ed at the tipis used. The herring bone
or a single cut isused, Cups are used to
receive the latex. The latex coagulates
quickly on exposure to air but appar-
ently not too quickly to prevent its
flowing down into the cup’s well. Water
is sometimes used in thecups to prevent
too rapid coagulation.

[APRIL, 1909,
In the case of the Manihot piauhyensis
and Manihot heptaphylla, the shorter
trunk and somewhat thinner bark than
the Manihot dichotoma are not suitable
for cutting, and by this method yield
little latex. pe Shipping mid to gd viole

THE NEW SYSTEM OF TAPPING
RUBBER.
EARLY YIELDS VERSUS QUALITY.
Dovusts AND FEARS,
The new system of tapping rubber is attain-
ing very considerable popularity. It is the
chief topic of discussion in rubber growing
circles, It promises to shorten the wait of
the planter; and impatient shareholders are
already feverishly. revising their prospects
in the light of its advent. ‘‘Our estimate
for the year is so and 80; but, wilh the adop-
tion of the new system of tapping, we expect
that this will be greatly inereased” has
become as essential (and as stereotyped) a part
of a Rubber Company Chairman’s annual
speech as the time-honoured and hoary formula,
‘‘The report has been in your hands for the
usual time and with your permission we will
take itasread!” It is natural enough that any
method of dealing with rubber trees, which will
render them productive two years earlier than
was anticipated when they were planted, should
absorb attention to the exclusion of all else and
wecan probably accept as true the current Hort
report that already some 120 Ceylon estates
have subscribed to the new method. The
pre-eminent advantages claimed by the new
system are:—Simplicity; Reduction in cost
of production; Little or no damage to the
trees; Reduction in labour force required;
and Quicker and increased returns. The last
of these is undoubtedly the one that has
proved the most attractive to producers and
shareholders; and now that they are becoming
accustomed to its dazzling glamour, which for
the time obscured all other issues, they are
beginning to realise that there are two sides to
the shield. Doubts and fears are forcibly ob_
truding themselves on the halcyon outlook. Two
points in particular are being much discussed ;
49
crease
and in our opinion these must be satisfactorily
answered and proved to the hilt by experience be-
fore the new tapping method can he pronounced
an unqualified success or hailed as a genuine
benefaction to the plantation rubber industry.
It may be safely assumed, so attractive are the
claims of the new system, that the great majority
of planters possessing rubber at all approaching
a tappable age will take it up, for—according to
Messrs. Lee, Hedges & Co.’s original circular, re-
produced in T.A, for December, 1908—‘‘By adop-
ting this system it is possible to secure from
young Trees (38-year-old and upwards) which
cannot under present conditions be profitably
tapped—a remunerative yield at a low cost not
possible by any other known method,” What
must be the inevitable result of this? In avery
short time a large quantity of inferior rubber
will be thrown upon the market, prices must
drop and the fair name of the Ceylon pro-
duct is bound to suffer in the eyes of the
buyer. The inferiority of rubber yielded by
young trees is a matter beyond cavil. ‘ In-
in age,” says Wright in, his ‘ Para
Rubber,” the standard work on the plantation
industry, ‘‘is certainly to be associated with an
improvement in the physical properties and
quality of the rubber, whether one considers
plantations of different ages or parts of the same
tree.” Again observers have shown that “ rub-
ber from young trees is adhesive and lacks the
required elasticity and strength.” StanleyArden
has shown that in parts of Malayathe rubber
from trees 32 to 4 years old is decidedly inferior,
The India Rubber Journal is quoted by Mr.
Wright as having described samples of Para
rubber from four-year-old trees ‘‘as being soft,
and would not stand much working on the
machine, while the value put upon them was
only equal to that fur ‘Congo ball or a similar
quality of African.’’’ And finally we may
quote the opinion of Mr. Wright on the sub-
ject, applied directly {to Ceylon :—‘ When
oneconsiders that the growth of the Para
386
rubber tree in Ceylon is such that a cir-
curmference of 20 inches cannot be attained
much before the fourth, fifth or sixth year,
it is obvious that, under ordinary methods of
cultivation, all ideas of extracting rubber from
trees under these ages should not be encouraged.”
It is therefore abundantly clear in our opinion
that early yields and correspondingly quick
profits may be obtained at a far greater cost
than the R500 necessary to be put in posses-
sion of the secrets of the new system.
As to the effect of the system upon the tree
itself, we are precluded from discussing this
freely because it would be unfair to the inventor
of the method to publicly state the manner in
which latex is extracted under his system. It
is, however, generally known that the bark of
the tree is conserved and left practically intact.
{ft is upon this point which doubt exists.
Rubber is extracted at present by removing
the bark of the tree: the existing doubt, as
put to us, is ‘‘ whether, after a period of tap-
ping, the latex cells will re-fill and continue
to yield rubber.” The point may be better
understood when we remind our readers that
“the bark, or—as it is better termed—the
cortex, is formed from within outwards ; new
cells are continually being formed which push
the older ones outwards. All these cells, at
some time or other, are liable to undergo decom-
position and to assist in the production of
well-defined tubes which become filled with
latex.” Will this action continue when the
tree has been tapped some time under the
new system? ‘Two years is the time esti-
mated to elapse before this can satisfactorily
be proved by experience. Personally we do not
regard this as a grave menace to the industry
although it is a point upon which we should like
to have the opinion of a competent scientitic
authority. It would appear, however, from an
opinion expressed by Mr. Herbert Wright in a
lecture at Kegalle, (assuming the point above
alluded to is satisfactorily settled) that the new
system is well-calculated to effectively prevent
the danger of vital injuries to the tree being
effected during tapping by the old method. Mr.
Wright said :—
It isnotin the extraction of latex that the
harm is done, so much as in the removal of the
bark containing that substance. The bark or
cortical tissue, which is removed in tapping
operations, contains organised systems of ele-
ments which are of vital importance to the plant
and on their health and continuity depends the
perfect distribution, mainly from above down-
wards, of the food materials elaborated in the
leaves. As a store house and conducting channel
the cortex is of vital importance to the plant, and
if it is removed too quickly, the life of the tree
may be endangered. ‘The rapid stripping of the
bark is an unnatural process, analagous, perhaps,
to the treatment meted out to cinchona trees—
though they did not flourish long—but not com-
parable with the natural peeling away of dry
bark. During ordinary tapping operations the
cortical cells are excised while they are in a
living condition, and are entirely removed at a
time when they centain reserve food intended
for the use of the plant; it also differs fromthe
The Supplement to the Tropical A gricullurist
natural peeling of the bark, in so far as the
average operator exposes the inner and more
delicate and vital components of the cortex and
cambium to atmospheric influences. Such treat-
ment does affect the vigour of the trees, and if
cortical stripping is effected much more fre-
quently than once in three or four years, I
anticipate trouble in the future.
It is well in this connection, and in connection
with the letter which appears elsewhere, of Mr.
H. A. Wickham (the veteran introducer of Ama-
zon rubber into Kew, whence it came to Ceylon
and the East) to remember that the latici-
ferous system of the rubber trees has no vital
association with other parts of the tree, andis
not like thecirculatory system of human beings;
itis almost useless during the life of the tree
and persists when the tree is apparently dead.
The latter of the two points dealt with above
is, however, one upon which our scientific
advisers are best able to sit in judgment. If
they pronounce the system one which can
be safely practised, it is certainly going to bea
splendid thing for the industry, if utilised only
on matured trees; because in other respects
it urdoubtedly does all that it claims. The
first pointcomes within the comprehension of all
interested in the rubber industry. By sending
rubber from immature trees to market we may
secure quick returns fora time; but the rub-
ber is bound to be less resilieht and strong
than that of our competitors taken from older
trees. It wiil snap when stretched, and the
inevitable tendency will be to throw the Ceylon
plantation industry into disrepute with the
buyers. This is a serious consideration and
one that should be carefully weighed before
the new system is applied to thousands of
young trees, the rubber from which is not really
fit to be placed on the market.
OPINIONS OF PLANTERS,
1
March 19th,
Dear Siz,—In your interesting article on the
new system of tapping rubber you lay too much
stress, | think, on Mr Herbert Wright’s ideas,
now getting rather out of date, I had the plea-
sure ot having as my fellow passenger on my
voyage out in the ‘‘Omrah ” last November, the
Chairman of the Lanadron Rubber Estates.
This Company spares no expense in having
scientific experts on their Johore property, who
are intouch with their consulting Chemists in
London, Messrs Clayton, Beade & Stephens, and
so far as these experiments had gone to Autumn
of 1908, the summary arrived at was thus:—
‘The quality of the Rubber is not affected
by the age of the tree that yields the latex.”
The effect of such tapping on the future life
history of the young tree cannot yet be deter-
mined, but the summary deals effectually with
your fear that such tapping on young trees will
affect the quality of the Rubber itself.—Yours
truly,
W, D. G,
and Magazine of the Ceylon Agricullwral Society.
[Is our esteemed correspondent ‘‘ W,D.G.” also
among those who yearn after the flesh pots of
Egypt as represented by immature rubber and
early dividends? It would appear so from
the tenour of this letter. We cannot for a
moment accept either of the assertions he makes.
We certainly do not think that Mr Herbert
Wright’s ideas are ‘‘getting rather out of date.”
Who, may we ask, has offered us any more
advanced ideas to supersede those of the
enterprising ex-Controller of the Experiment
Station or added materially to our stock of
knowledge on the genus Hevea Brasiliensis
since Mr Wright published his magnum
opus? In what respect, will ‘‘W. D. G.” tell
us, have his ideas become obsolete ? As to
the statement made to our correspondent by
the Chairman of the Lanadron Rubber Estates
Co., we cannot accept it against the almost
unanimous opinion of all who have any claim to
be regarded as rubber experts. It may be true
that “The quality of the rubber is not affected
by age of the tree that yields the latex ’—when
the treescompared are ail over, say, ten years of
age. This is no new discovery. It was men-
tioned in the Lectures at the London Rubber
Exhibition, and Mr John Parkin, m.A., declared
‘* Personally I should be rather surprised to
find any marked difference in the quality of
the rubber drawn from ten year old trees as
compared with that from 20 year old trees, all
other conditions being equal.” Does the
Lanadron Chairman or ‘‘W.D.G.”, however,
seriously ask us to believe that rubber froma
three-year-old tree is equal in quality to rubber
from a 20-year old one? The suggestion is
absurd and opposed by all authoritative opinion,
Mr C K Smithett pointed out at the first
rubber exhibition in Ceylon that the best plan-
tation rubber—with greatest tensile strength—
was obtained from the oldest trees. By way of
warning he observed ‘‘Bad reputations are dif-
ficult to be got rid of ; so do not let. your rubber
acquire a reputation of being weaker than fine,
hard cure Para.’?’ In the 1908 Rubber Exhibi-
tion in London Mr Philip Schidrowitz in the
course of his paper ‘tthe Relation of the Manu-
facturer to the Consumer” declared: ‘‘ Although
the advantages of plantation are both numerous
and important, there is no use blinking the fact
that much of the plantation rubber now being
produced is in one respect decidedly — inferior
to the high class wild product, namely in
regard to ‘nerve’ or strength or resiliency.’’
And he added subsequently : ‘‘ There is one
point on which every manufacturer with whom
I have discussed this question (at the Rub-
ber Exhibition and elsewhere) is agreed,
and that is that the plantation product
varies very widely in regard to strength.” On
the same occasion Mr John Parkin, M.A. stated:
‘‘Though plantation rubber has frequently.
obtained a higher price per lb. than the best
Para, yet I believe it to be a fact that the lat-
ter, if as pure and free from moisture, would
command a better figurein the market, as it
ogsesses tougher qualities. Fine Para, then,
fe somewhat superior properties to the first
grade piantation rubber hitherto supplied.”
Our position, therefore, is this: authorities
agree that the one point 1 which our rubber is
387
inferior to the wild product is in nerve and
strength. We have been told so all along and
the defect has been attributed to our trees
being so young. If we are to successfully come
pete with our “wild” competitor in comman-
ding the attention of the manufacturer we must
do our best to overcome the reproach of weak-
ness in our product. The new system of tapping
does not help us to do this. On the contrary, it
accentuates the defect and is bound to make it
more prominent than ever it was to manu-
facturers. Plantation rubber is still more or
less in the experimental stags as far as the
manufacturers are concerned ; if itis tried and
found wanting now, there may be difficulty in
finding a market for the product when the
plantation industry approaches more closely its
maximum output. In the above remarks we are
thinking of the industry as a whole; and are
quite well aware that there are not a few estates
in Ceylon which produce rubber from well
matured trees quite equal to the best wild rub-
ber in strength and vastly superior to it in
purity.—A. M. & J. F.]
II.
Kelani Valley, March 20th.
Srr,—I am glad to see you giving a word of
warning as to the quality of rubber which will
be harvested if early tapping of rubber trees
becomes general all over the Island—for it isa
fact which every practical rubber planter knows
that rubber harvested from trees under 6 years
old no matter what their girth, is less resilient
and is full of resin.
This fact—though it must be known theore-
tically by the Upcountry rubber Visiting Agents
and Directors of Lowcountry concerns (for I
presume they read up authorities on the pro-
duct which they report on or speak about,
though they have no practical hnowledge of it)
—is severely let alone and never whispered
about, like Coast advances and other awkward
planting subjects—which would interfere with
share rises and dividends ; and so orders are
given to the wretched Superintendent to tap,
tap everything you can, and stop talking about
quality and prices which are inthe lap of the
Gods and inthe ignorance of so called rubber
experts at Home and in Colombo.
Re the new tapping system which you hint at
and evidently know, though you rightly say it
would not be fair to the Inventor to mention,—
Is it a fact that increased returns per acre per
annum will be obtained ? I doubt it, but am un-
able to give my arguments against such a result,
for the same reasonas yourself; I will simply
state what every practical Planter knows, that
an increased yield for atime can be got from
any of the old systems,
The new system is undoubtedly cheaper and
a great saving of labour and that alone is worth
paying for to learn; but there I think its
advantages end, and it is sickening to read day
after day of one Director after another getting
up at meetings and talking of doubling and
trebling the crop for the current year by the new
system, a system which has not yet beon tried
& your.

Ceylon rubber has a fair fame at present—
perhaps not as unstained as a few years ago
when only old trees were being tapped ; but it
isa certainty that if wetap 3 and4 year old
trees as Messrs. Lee, Hedges & Co. advise in
glowing terms can be done remuneratively, that
in a fewshort months the price of Ceylon rubber
will be so far below hard Para that it will only
be seen by those buyers who are trying to imitate
the Germans in turning out cheap goods with
cheap and nasty materials.—yours faithfully,

Dear Sir, —If ‘W. D. G.” thinks Mr. Herbert
Wright’s ideas are now getting rather out of
date, I should be glad to know whose idea is
the much-talked-of new tapping system. I
think it is Mr. Wright’s, as could be seen from
the following. Mr. Wright, when questioned by
your reporter, said :—‘‘ Theoretically speaking
the milk from the tree 1s of no use as food to the
plant and tf it can be extracted in good quantities
fromthe tree without cutting away the bark tissues,
say by apricking method, it would perhaps be
better for the tree.’ When further questioned,
‘‘Are all these trees scraped before tapping ?,”
he replied : ‘‘yes, but only to ensure that the
latex shall be free trom bark impurities.” Vide
Tropical Agriculturist Vol. XXV page 317.—
Yours faithfully,
T. Es.
{We welcome these expressions of opinion from
rubber planters. With regard to the point
raised by ‘‘W.B.D.” as to whether the new
system will increase yields, we are iin a
position to say he is not. singular in his
doubts on this point. But, aehough the
new system may not increase the yield from
individual trees, it will largely increase the
yield from the whole estate by rendering
possible the tapping of immature trees. It
is this probably the Directors have in mind
when they ‘‘talk of doubling and trebling the crop
for the current year”; it is somewhat alarming
to find the unanimity with which they seem to
have made up their minds to get quantity at
whatever ultimate cost. Our correspondent
“T.L.8.” points out that, far from being out of
date, Mr. Herbert Wright’s ideas led directly
to the invention of the new system of tapping.

PARA (HEVEA) INDIAN RUBBER
CULTIVATION.
Royal Colonial Institute, Northumberland
Avenue, London, W.C., Feb. 8th, 1909.
Dear Str,—Remembering the interest which
you have always displayed in the subject of the
cultivation of the Hevea Indian rubber, will
you permit my sending you again a note of
warning—against certain dangers—for you to
make use of, should you see occasion. The
occasion already (as I think) presents itself,
seeing the too common acceptance by Eastern
estates of methods unsuited to this tree:
The Supplement to the Tropical A griculturist
one, the plantation and cultivation of which is
of most promise and of growing magnitude.
One point to be considered is the ill-effect of, or
from, shock or over-strain, whereby the general
vitality of the trees may become impaired; and
the incidental and cumulative effect of such
treatment, likely to render or lay open, through
a lowered vitality, tothe inroads of morbid or
fungoid growths. In equatorial jungle-land and
soils, germs which are capable of inducing
disease are, of course, generally and naturally
present ; but in the case of tree or plant nor-
mally healthy, they remain innocuous by reason
of natural resisting power. If, however, the
vitality of the subject be lowered, either directly
and locally by physical injury, or indirectly
through a general lowering of vitality in the
body, this resisting power becomes impaired; and
so much, until the vital energy be restored.
- When vitality is impaired, spores, of morbid
growth, are enabled to enter, find lodgment,
settle and multiply in the weakened tissues—if
not overcome,
As in our own conditions of life, we all
breathe and take in the same germ-conveying
air and foods, yet without material hurt or
damage unless, and when, they are enabled to
obtain lodgment in the system through cause,
2.e., accidental injury, overstrain or other where-
by natural vitality is lowered below normal.
So in the community conditions of plant-life
in plantation and estate. Thus, as I have always
held from the beginning of this industry, me-
thods entailing removal of bark-tissue, the all
too close planting and spacing, unsuitable culti-
vation (methods now too common on many
HKastern estates), constitute a danger, as being
unsuited and unsuitable toa forest tree of the
nature and habit of the Hevea; and it would
be hardly matter for surprise should sign of
root-failure, and its consequences, supervene
and show itself in such case.—] am, yours
faithfully, H. A. WICKHAM
RUBBER IN EAST AFRICA.
INTERESTING INFORMATION.
We quote as follows from a business letter
of enquiry :—
Blantyre, Feb. 12.—You will be interested to
know that Ceara Rubber is being widely planted
here and this Company, the Blantyre and East
Africa Ltd., will have
NEARLY 1,500 ACRES UNDER CULTIVATION
jin this product by the end of March.
Some of this acreage is now 44 years old and
the trees range in age down to those planted
out in the current season. Ceara does well
here. We are anxious to learn the best system
of tapping ; the system spoken of by Messrs.
Lee, Hedges & Co. (as shown in your journal)
might suit Ceylon with its moist climate but
might not suit this country which has a wet
season for say five months and a long dry sea-
son of seven months. Will the system apply
equally well to a country which has a continen-
tal climate? Briefly our conditions are as
follows :—
*
and Magazine of the Ceylon Agricultural Society.
Rains commence November and end March-
April. Light showers in May gradually getting
colder, and dryer. June cold, sometimes misty
but on the wholedry. Atmosphere gets drier
and hotter till November when the shade tem-
perature occasionally reaches 95. Rains break
again in November. Rubber is leafless as a
rule from September to November. Rubber as
tapped runs in wet months, but only older
trees run in the dry months and that not
so freely. If outer bark is removed and inner
bark pricked, in dry season, rubber quickly
coagulates. I may say that the rubber is ex-
cellent and our only difficulty is the tapping,
2.€., what method will give the best results with
least danger to the tree.
Tapping with patent knives by making grooves
seems to us not so suitable. The outer bark would
require to be removed and in the dry season, as
has been found in India, this is apt to harm the
tree—as towards the end of the dry season the
tree is leafless, the atmosphere is dry, and the
inner bark gets dried up; the sun plays on it,
and it is apt to be a severe tax on the tree.
Moreover it is difficult to get the rubber to run
freely except in the rains.
Would the new system suit the dry northern
districts of Ceylon, where Dr Willis is at present
experimenting with Ceara? We have four-and-
a-half year old trees running from 14 inches to
20 inches in girth at three feet from the ground.
[We have forwarded the letter quoted from
to Messrs. Lee, Hedges & Co., for reply to the
special point raised; but will be obliged for
any recent information from rubber growers
who have tapped Ceara.—A. M. & J. F.]
RETURN OF MIX. C. 0. MACADAM.
His Opinions oN RuBBER MATTERS.
Mr C O Macadam, who recently returned
to Ceylon is not so sure—says our contem-
porary—that 1912 is the best year for the
next Rubber Exhibition, and thinks that the
claims of 1911 may with advantage be consi-
dered. Heis of the opinion that the recent
Exhibition suffered by being held in September.
So many people who would otherwise have at-
tended were away shooting or on holiday. A
good month, he thinks, would be May,
THE MANUFACTURED ARTICLE,
Mr Macadaw thinks that for a thorough test
of rubber-manufactured articles they should be
made and kept for a year or eighteen months.
He holds that it would be an important advan-
tage if Ceylon could have experiments put
through to the finished article from rubber
harvested from different aged trees, and not only
that but from different ages of renewal of bark.
Such experimental work would formerly have
fallen to Mr Herbert Wright to carry out, but
Mr Macadam did not think there was any one
specially doing that work now. Mr Macadam
holds that plantation rubber should always be
estate or Company marked, if possible; that
there should be care in sorting true to grade;
and packing in clean packages, and the preven-
ting of smail chips of wood and dust becoming
attached to the rubber,
389
Tus New Tarrinc System,
Mr Macadam preferred not to say anything
about the new tapping system until he
knew more about it. With regard, however,
to the point that there was a danger to the
industry in tapping too young trees, he said:
‘““[ have always been against tapping im-
mature trees, and the question has not been
decided at what age the tree is mature;
it can only be settled by sending a semple to
a manufacturer to be converted into rubber.
Even then it cannot be decided till the rubber
has been allowed to remain for about eighteen
months. The fact that you cannot tell what
therubber will prove, looking at it immediately
after manufacture, makes the danger greater.”
THE RUBBER INDUSTRY IN JAVA.
Mr, TAcsor’s IMPRESSIONS OF HIS RECENT VISIT.
Mr, G A Talbot, on bis return from a visit to
the Straits and Java, gave a Ceylon Observer
representative a good deal of interesting informa-
tion with regard to planting matters in Java.
He was first asked if he could give his impres-
sions of Java rubber cultivation methods as
compared with those practised in Ceylon.
‘‘Well,” he said, ‘‘it is difficult to give an
opinion about Java rubber generally, because
the soils and climates differ very much. Java is
avery big country, and inthe West you havea
red ferruginous soil, more or less _ stiff, whereas
in the East you have a brown volcanic
loam. Not only do the soils differ but the
labourers and people that work them, and as
regards the Java methods they differ very much
indeed. You will find hardly any two estates
working the same. Perhaps the characteristic
of Java planting is that they have
TWO PRODUCTS GROWING
at the same time. With Hevea they grow Coffee
Robusta, which is a very hardy coffee that has
no leaf disease and bears as much as nine to ten
hundredweights an acre inthe third year, It
grows well with Hovea asit likes shade and
damp.
How are they off for labour in Java?
It varies. In West Java it is very cheap,
where they employ the Sundunese. In East
Java it is not so plentiful, but there are plenty of
labourers because in Java there is a
POPULATION OF 33,000,000 JAVANESE
and the natives are willing to work, in fact
they are obliged to work. There .is such a
large population and they have to work for
their food.
Is labour fairly cheap ?— Yes,
sevenpence a day for men.
Nor Mucu Tarpina.
Have you found much tapping done yet ?—
No. If saw very little.
THREE Days By Rat,
In answer to questions about the acreage
and outturn for 1908, Mr Talbot said:—‘‘I cannot
tell at all. 1t takes you three days’ travelling by
rail all the time to go from one end of Java to
the other, so you can imagine what itis, and
as they grow dadap with their rubber you
cannot see very far; in fact, you see hardly
any rubber,”
It is about
390
THe CLEAN WEEDING QUESTION.
Do they go in for clean weeding ?—The younger
plantations are clean weeded. The old Java
system was to let the soft weeds grow and then
to cut them off with a sort of sickle. It is found
that clean weeding is the best. It is much cheaper
aud better forthe growth of the product.
GREEN MANURING.
Do they go in for much green manuring ?—
No, they do not do any in Java, the soil is so
rich. The dadaps are merely for shade. 1t is
used very much because in growing coffee they
have had to have shade and they go on with it
because it prevents wash and assists to keep
down the weeds,
RUBBER EXTENSIONS; THE Pric# or LAnp.
1s there much extension being done in rubber?
—Obh yes, a good deal of extension is being
done in rubber.
What is the present average price of suitable
land obtainable ?—It is difficult to answer that,
because it is very difficult to get landthere. You
have to get a lease from the Goverment; and if
you apply for land,itis very possible they will
say it is required for the natives, The methods
are different from those in Ceylon. The Govern-
ment very often will not allow youto take up land
at all, but there is land which has been leased
before and the price of that is from 40 to 50
gilders a bouw, £2 to £3 an acre, that is, to buy
the right of the lease for 99 years. You still have
to pay the rent. It is apremium asit were. A
gilder is 20 pence, twelve to a sovereign.
THe Cost oF BRINGING INTO BEARING.
At what cost peracre is rubber being brought
into bearing inJava?—I know an estate that has
brought in at £16 an acre; but I can’t answer
for anything else.
Tue Kinp or LAND ON WHICH If IS PLANTED.
On what kind of land is it mostly planted ?—
Mostly in Hast Java on very good soil with
gentle slopes at the bottom of the mountains.
It is a very mountainous country, some of
the volcanoes being 10 or 11 thousand feet
high. It is gently undulating. The valleys
are kept for the natives for paddy. Paddy
cultivation ig extending very much and they
lease to the Kuropeans the lower slopes of the
voleanoes. Very often you have chosen what
you think is a good piece of land and they
say: ‘* Oh! we must keep that and sell it
to the natives.”
RussER IN THE MALAY STATES.
Mr. Talbot also mentioned that rubber was
doing very well in the Malay States. They
had the Fomes fungus on the roots about two
years old; butif it were tackled, it could be
kept in check. It spread from one to the other,
but whenatree died, you dug a trench round
to stop it. There was nothing to be afraid of.
They knew nothing about the new tapping sys-
tem inthe Straits. As far ashe had heard it
answered very well. Of course they had had
no experience yet of what ettect it would have
upon the treo. As far as they knew it was all
right.
The Supplement to the Tropical Agriculturist
Tra MATTERS,
What are the chief points in which tea culti-
vation in Java differs from that in Ceylon ?—I
didn’t see any tea, so [ can’t altogether tell
you; but the chief difference is that the
labourers come from the villages, and so you
have not got the same skilled labour force you
have in Ceylon. In Ceylon there is a labour
force which remains on estates. In Java
they change, so that you have not got the
same trained force. There is, however, no doubt
about the labour because the Javanese would
sooner work in Java than go abroad.
Nor SucuH Goop Tza.
_ In what respects are tea planting methods in
Java superior or inferior to those in Ceylon ?
—They don’t produce as good tea in Java be-
cause of the labour, and because it grows so
quickly and so rankly, owing to the fertility of
the soil and the climate.
THE CEYLON RUBBER INDUSTRY.
We are surprised to find in the official Journal
of the Jamaica Agricultural Society the follow-
ing grossly inaccurate and mischievously mislead-
ing report on the Ceylon Rubber Industry:—
Rubber.—Ceylon planters are finding that
they have fully two years longer to wait than
they anticipated for the tapping of the rubber
trees. Rubber planted in tea land has not come
on nearly so well as it promised. Rubber in
the Malay estates in general is two years earlier
than in Ceylon, the soil and climate seeming to
suit it better. The mistake that many men
made was expecting rubber to grow on any soil,
and so simply planting it broadcast. Many are
finding out their mistakes now, and in many
cases they are abandoning their fields and going
back to their tea. The latest reports say that 25
per cent of the rubber planted in Ceylon will
never yield latex at all. There is a_ brilliant
future for well selected plantations with the
product at anything over 2/9 per lb., as well-
managed concerns are turning out good stuff
from 1/ to 1/6.—Correspondent.—Journ:l of the
Jamaica Agricultural Society for January.
Jt is as well that this journal and its correspon-
dent should know:—(1) That plantation rubber in
Ceylon is coming into bearing,if anything sooner
than was expected during the early days of the
industry,and that under the new tapping system
rubber trees will yield latex at a much earlier
age than under the old system ; (2) that the
abandoning of fields of rubber is entirely a myth,
and (3) the statement that 25 per cent. of the
rubber planted in Ceylon will never yield
latex at all is a gross exaggeration for which
there is no foundation whatever. As a matter
of fact the Jamaica journal’s correspondent
betrays a profound ignorance of the whole
situation. So far rubber has more than come up
to expectations in Ceylon, and the fact that
estates are already producing it for well under a
shilling per |b and selling their whole crop ahead
for the current year at from 4/ to 5/ per lb is
evidence which justifies the belief that the
future is brighter than the past year at any rate.

TEA PLANTING IN JAVA.
We direct attention to the letter which Mr.
Hugh Tomlinson writes us on this subject, offer-
ing an alternative method of cultivation to that
advocated in the ‘' Instructions to Saperinten-
dents” published by us last month. Mr.
Tomlinson refers to our ‘‘very hearty endorse-
ment” of these methods; but we merely quoted the
opinion ofthe planter who favoured us with the
“instructions” and invited criticisms upon them,
We are well aware that the system of cultivation
which suits one estate may be quite unsuited to
another estate on which different conditions
obtain. Onthe whole clean weeding has answered
exceedingly well in Ceylon, although in Assam,
where it is not practised, the industry does not
by any means suffer. Mr. Tomlinson asks our
opinion on the two points he raises in his letter.
Itis a matter for the practical planter, however,
and we trust some of our planting readers will
favour us with their views on these matters.
MR, TOMLINSON’S LETTER.
Bandoeng, Java, 4th March.
Srr,—I have read with interest ‘‘ Some Valu-
able Planting Instructions” in your March
number. Your very hearty endorsement might
lead one to believe that this was the only satis-
factory system of cultivation.
May I suggest an alternative one for tea,
whereby the good soil isalso preserved ? (Your
anonymous instructor can only be referring to
preservation of soilas none of the grasses he
mentions would improve it, Their names are
Hydrocotyle Asiatica excellent for preventing
wash when planted in the rows where there are
no waterholes, Impatiens Latifolia, Senecio
Javanicus and Richardsonia Scabra.)
Clean weeding with a four inch hand fork,
whereby the good tilth sostrongly recommended
by Dr. Willis in the October T. A. is obtained,
and the use of waterholes, prevalent throughout
W.Java. The waterholes are placed horizon-
tally, from 1—13’ deep, about 6” broad, of
varying lengths and separated by 6” of solid
ground. My sketch may show the system ;—

At each pruning the waterholes are moved
down a row, when the old ones can be used
for burying the prunings in. Surely as little
soil is lost by this method as in a dirty garden ?
The Manager of Pangledjar has told me that
he has made exhaustive tests of clean and dirty
gardens and has proved both by crop and chem-
ical analysis that clean weeding is the best for
his estate. That his opinion ought to carry
weight is proved by his figures. He has 479
bouws of tea of which 67 were planted in 1908.
Of the remaining 412 bouws 64 are old coffee
gardens replanted with tea only 1, 2&3 years
old, which naturally give an inferior production,
yet the crop for 1908 was 850,855 Ibs or an
average over 412 bouws (721 acres) of 1180 lbs
peracre, Pangledjar is 230U’ a. s, 1. and is a by
no means flat estate. The oldest tea is 8 years.
Nett price costing 54d, f.o.b 12d,
I should very much like your opinion on this
and my next point, as I should have thought it
quite wrong for anyone to dogmatise, as your
anonymous instructor has done, about one
method for several estates.
Most Managers here dig a newclearing as
deep as they can afford—say anything up to 24.’
{ find however that. a few who are obtaining
wonderful results dig as little as 3’—4.” The
latter argue that the young seedling requires
the good soil on the surface, and that as the
roots grow deeper the humus is gradually worked
in deeper too, whereas by digging deep origi-
nally the seed is planted in more or less un-
sweetened ground and the growth is conse-
quently retarded. Do youconsider these reasons
outweigh the advantages of deep digging ?
Malabar, pace Mr Bingley, is not our only
wonderful tea estate, yousee; I am only waiting
for one or two annual reports to shew there are
others too. Apologising for the length of this
letter, lam, Sir, yours faithfully,
HUGH TOMLINSON.
SHOT-HOLE BORER AND PREDA-
CEOUS ENEMIES.
Kandy, March 16th, 1909.
Dear Sir,—I beg to forward herewith.....
copy of letter received from Mr. E, E. Green for
the favour of publication.—Yours faithfully,
ALEX. WARDROP,
Secretary, P. A. of Ceylon.
(Enclosure.)
Mote Hall, Bearsted, Kent, 23rd Dec., 1908.
The Secretary, Planters’ Association of Ceylon.
(Ln continuation of my letter of 8th December.)
DEAR Sir,—The result of my enquiries as to
the habits of Clerus formicarius corroborates my
belief that the introduction of the insect to
Ceylon would be unaccompanied by any danger.
The species of this genus are known to be purely
insectivorous and are parasitic upon various
small boring beetles. The Clerus itself is con-
siderably larger than the insects upon which it
preys. But it lays its eggs in the tunnels of the
borers and its larvee enter the galleries and
devour the original occupants. In Hurope, the
insect is found -principally in fir trees, which
fact leads one of my correspondents to doubt
whether it would accommodate itself to the
different conditions of the tea-bush, But an-
other entomologist, who is familiar with the
species inits native haunts, assures me that it
occurs also in many other trees and he sees no
reason why it should not be able to exist on any
tree that would supply suitable provender in the
way of boring beetles and their larvze,
392
Under these circumstances, the experiment
appears to me to be wortha trial. [ anticipate
that the cost will be quite nominal and, should
the experiment fail, no harm can come of it. If
the insect finds its environment unsuitable, it
will merely fail to establish itself and die out.
I find that Clerus formicarius occurs throughout
Great Britain, and that it can be taken abun-
dantly in parts of Scotland. A journey to
Germany would therefore be quite unnecessary.
The habits of the insect should render it easily
transportable by post, as it could be packed in
decayed wood in which it would most probably
travel quitecomfortably.
My entomological friend has very kindly
offered to arrange for the collection of a con-
siderable number of the insects. and will send
them on to me in the course of the summer.
It appears that the Clerus is ‘in season’ about
midsummer, I have felt myself safe in guaran-
teeing that the cost of coliection and transport
(a matter, probably, ofa few shillings only, or
at most of two or three pounds) will be defrayed
by the Planters’ Association. I shall be obliged
if you will endorse this small liability.—I have
the honour to be, your obedient servant,

GENERAL REVIEW OF JAVA TEAS
IN 19038.
[FRom tHE Export BoureEaAu.]
Bandoeng, February, 1909.—The past year of
1908 has seen a great advance in the Java tea
industry and results must have been satisfactory
to all connected with the trade in this country.
Total exports have shown
A 25 PER CENT. INCREASE
on the previous year and have now reached
a total of 33,254,124 Half Kilos or 36,579,536
English pounds, against 26,624,002 H K or
29,286,402 English pounds in 1907 ; and against
15,214,234 H K or 16,736,157 English pounds
in 1901; which means that production has
more than doubled in the last 8 years. The
results of the new clearings and planting of
the last few years are seen in tbe figures of
1908; and it is certain that each coming year
must show a further and regular increase in
our exports, because planting has for the past
few years been general (to a large orsmall extent)
on nearly all estates and in many cases these
extensions have been to quite large extents.
SEVERAL NEW COMPANIES
have been started during the past year and it
seems probable that we shall see a 50 millions
export for Java teas within the next seven or
eight years or so. It may be here mentioned
that the
IMPORTS OF TEA SEED FROM BRITISH INDIA
during 1907 and 1908 are spoken of as having
been invery much larger quantity than in any
previous years. The deliveries of local Java
seed are also of very considerable quantity and
the many estates that are producing good
seed have no difficulty in selling their entire
The Supplement to the Tropical Agriculturist
crops. Holland has in 1908 received 184 million
half kilos against 144 in 1907; England nearly
114 millions against 84; Russia (including ship-
ments through North China ports) 3 millions
against 24; while on the other hand both
Australia and ‘‘ other ports’ show a decrease in
the quantity received, namely 300,000 half kilos
against 660,000 for Australia and 180,000 H.K.
against 851,000 for ‘‘other ports.” The total
increase in exports from lst January to 31st
December, 1908 to all ports is 6,630,122 half kilos
or 7,293,134 English pounds.
PRICES
during 1908 taken generally have been good for
the class of tea which Java produces; which
amongst the world’s supplies are, with a few
exceptions, classed as ‘low, and medium grade ”
teas. The prices for such teas have not .of
course kept up to the extraordinary high level
of the latter part of 1907, but on the other
hand they have never fallen to that very low
basis which is sometimes seen for the inferior
sorts of teas. In Amsterdam the year started
with extremely high rates for low and medium
sorts, but from February there was a steady
and big decline in prices right through the year,
until the January basis for ordinary PS. Pekoe
and BP’s fell from 40, 41 and 41 cents down
to 28, 30 and 32 cents respectively in November
and December. with an average rate of 33, 34
and 354 cents for the 15 sales of the year. For
ordinary Dust, Broken Tea and Pekoe Fannings
the decline was from 38 and 40 cents to 23 and 25
cents, with an average rate for the year of 29
for Dust and 32 for PF’s and small leaf Broken
Teas. Teas of very good medium quality of
the Gn. Malang, Gn. Tjempaka, anjairan,
Pagilaran and Pasir Nangka type in January
stood at 45 cents for PS. Pekoe and also BOP
grades, but selling irregularly and generally
lower, these prices fell by July to 35, 39 and
41 respectively, with however the good average
price forthe 15 sales of 39, 421 and 434 cents
for PS, P and BOP. Well made OP’s of
medium and finer sorts were always in good de-
mand and the prices ranged between 50 and 58
cents for the finer teas; and between 38 and 44
for those of medium grade, andaveraged 524 and
40 cents respectively. The best BOP’s, with
which Amsterdam is not wellsupplied (all the
best teas going to London) did not fetch good
rates until right at the end of the year. Prices
varied between 43 and 63 cents but only once
was there a price of over 50 cents and the average
Amsterdam rate for the 15 sales was but 48 cents
with a highest rate in nearly all sales of 43 to 47
only. Witpunt Pekoes also saw a big decline in
prices with an 80 cents rate in December against
101 cents in January, for teas of the Soekasarie

the market ran much on the same lines as that of
Amsterdam, except that medium, good mediuin
and finer BP’s and BQP’s were generally on a
higher level on the Anglish market. Finest
BOP’s of theGoalpara type sold well throughout
the year, the price only once falling below 104
pence, while the average for the 16 sales that
have been quoted was 11 pence. Good BOP’s with
good tip and strong colory liquors of good me-
dium quality of the Perbawatie, Tjiwangie and
and Magazine of the Ceylon Agricultural Society.
Djati Nangor type started on a rather low basis
at 8 to 84; but they sold better as the year pro-
ceeded, until prices of 94 to 105 were reached in
August and maintained till the end of the year.
Gedeh teas did not, till late in the year, show
their usual fine quality and the price of his
BOP didnot touch 10 pence until August; but
with improved quality, the prices advanced until
the Goalpara level of 11 pence was reached and
kept to until the ond of the year. Good liquoring
medium grade teas without tip, of the Malabar
BP type, which are particularly suitable for
London and for which there is always a great
demand, sold well throughout the year, with a
lowest price of 7 pence for a few sales and a
highest price of 8} and with an average rate for
the 12 months of 734 pence, against 74 in 1907.
For ordinary and low grade teas, we find that
prices in January were standing on _ the
unusually high basis of 74 and 7? for Dust,
BT, BP. PS and Pekoes; but these prices
by February had already fallen to 64 63 and 7
pence, and by September/October the quotation
had further declined to 3? for Dusts, 5 for PS,
54 for Pekoe and 5 for BP’s. The lowest
quotations for clean ordinary teas during the
year were as follows:—Dusts 33; BT’s 44; PS
5 pence ; Pekoes 54 and BP 54; but the average
rate for the whole year for all these teas is
much-above these prices and stands at 54; 5%;
6 ; 62 and 6) respectively.
It will be seen, therefore, that 1908 has for
Java been
A RECORD YEAR
as regards the quantity of tea produced and that
for the class of tea that we produce, the prices
have throughout the year been on a satisfactory
and certainly a good paying basis for estates of
all elevations and of all qualities, The outlook
for the present year is good. With average
weather conditions we must see a further in-
crease in our exports, as itis only a few of the
very oldest estates that have reached their full
production ; while on the other hand there are
probably but few who have not young gardens
still coming forward. It must also be noted
that the teas grown by the native population
and sold as green unmanufactured leaf to Ku-
ropeans is now a very big item and is still
increasing. As regards prices it is impossible to
make any forecast, but it is satisfactory to
already see a considerable recovery from the
lowest point of the market in October/Novem-
ber last for low grade and ordinary sorts.
Below will be found statistics of Java exports
during the past 8 years, and also a table of
Amsterdam and London selling prices in 1908
and 1907. [We quote only the former for 1907-8.

THE CULTIVATION OF PASS!IFLORA
FCETIDA AND MIKANIA SCANDENS:
TO KEEP DOWN OTHER WEEDS,
By M. Ketway Bamper.
The former plant, which grows luxuriantly in
the dry and wet zones of Ceylon and the rich allu-
vial soils of the Federated Malay States, was re-
commended to be grown on estates badly infested
with lalang, in order to choke out the grass and
other jungle growths, and provide a dense cover-
ing of organic matter over the whole surface. of
the soil, Its use was first suggested in the Fede-
rated Malay States about a year ago, when it
was noticed how the plant was completely over-
ranning the abandoned Malay campongs, and
choking out every form of weed in them, inclua-
ing the much-dreaded lalang.
The cost of digging out the latter to com-
pletely eradicate it was proving prohibitive,
oftenas much as $65 or R118, per acre; and
many estates could not afford this enormous un-
remunerative outlay. Ordinary weeding also was
proving in many cases very expensive, aud a
heavy drain on the reserve capital for bringing
the planted areas into bearing ; and it became
necessary to findsome means of reducing ex-
penditure without injuring or delaying the
growth of the rubber. From the climbing
habit of the plant it spreads more rapidly over
strong growing lalang or small jungle than over
a bare soil, as its tendrils run over the tops of
plants, gradually smothering and_ bearing
them down asthe weight of leafy matter in-
creases. [tis therefore unnecessary to cut the
grass before planting the Passiflora {better
known as Passion Flower.—Eb., C,0.]
(n all estates it is customary to keep the rows
of rubber jor 3 ft on either side free from weeds,
and to utilise the plant it is best planted up
the borders of the clean rows, and induced to
grow outwards over the intervening weeds.
For lalang, a Selangor planter suggests a
method adopted by a native tribe of tying large
double-handsful of the growing grass together
with a few blades of the grass itself. This com-
pletely prevents growth, and the rain in the
tied bundle soon rots the growing points. By
planting cuttings or seed of the Pussiflora
between the bundles, the whole field will be
over-run in a few weeks or months and the
lalang entirely destroyed,
When the growth has attained its maximum,
and before the plants die down, the whole mass
of material, usually 12 in. to 18 in. deep, can be
rolled up like a huge carpet, leaving the surface
soil in a perfect loamy condition, and quite
clean and free from weeds. Such material
is best mulched in large rings round each
rubber tree, so that there is no continuous
line of dry material running through the field,
though the chance of damage from fire of such
materialis very remote.
Unlike Crotalaria, this plant is not legumi-
nous, and consequently does not increase the
total nitrogen in the soil. But from its dense low
habit of growth, which entirely covers the soil,
304
keeping it constantly moist, and the large
amount of organic matter resulting from the fall
and decay of the leaves, &c., the beneficial effect
is very marked. This is especially so on soils
poor in organic matteras are many of our Ceylon
soils, and for products, such as Para Rubber,
which require a humid atmosphere and an
ample supply of moisture inthe soil.
The composition of the plant is shown by the
following analysis of the various parts made by
the Acting Chemist, the whole plant when sun-
dried losing on an average 70 per cent. of mois-
ture : --

The proportion of nitrogen is very similar to
that in some of the leguminous plants, but in
this case ithas been entirely derived from the
soil, The chief ash constituents absorbed are
lime potash, and magnesia, with a smallamount
of phosphoric and sulphuric acids.
The plant appears to have the power of readily
decomposing silicates. All the nitrogen and
mineral matter is, of course, returned to the soil
on the decay of the plant, and left in a readily
available condition for the other product.
An average growth of the plant 10 in. deep
yields about 26,100 lb. of fresh green material
per acre, or, allowing 70 per cent of moisture
lost on air drying, equals 7,830 lb. of air dried
material. This amount of matter would contain
the following quantities of the chief consti-
tuents per acre :—
169 lb. nitrogen
the latter containing—
500 Ib. ash
155°6 Ib. lime 32°8 lb. sulphuric acid
64°5 lb. magnesia 21°6 lb. chlorine
85°0 lb. potash 21'5 lb. soluble silicates
29'3 lb. phosphoric acid
Another plant of somewhat similar growth,
which during the last few years has spread
enormously in Ceylon, is the Mikania scandens,
belongling to the natural order Composite.
It can be seen covering the scrub jungle and
trees along the Colombo line from Peradeniya,
and has spread down the Mahaweli-ganga to
Trincomalee. Under suitable conditions of soil
and climate, it should be as useful as Passiflora
fetida in smothering other more harmful
weeds, especially coarse grasses. The following
analysis shows its chemical composition :—

Mikania scandens thus differs considerably
from the Passiflora fetida in containing only
about one-fourth of the lime, and two and a
halftimes as much potash. It would, therefore,
while growing tend to compete more with the
rubber, which also requires much potash, but
this would be returned to the soil as the plant
decayed. In rubber it should not be planted
within 4 feet of the stems, and care should be
taken that it spreads over the intervening space,
and not beallowed toclimb the trees themselves.
The weight of green material per acre is vari-
able, but is very similar to that of Passiflora
fetida, and would represent the following
amounts of plant food removed from the soil per
acre, but returned again on the decay of the
plants :—
88°93 lb. nitrogen
286'10 Ib. ash
containing—
23°46 lb. line
20°14 lb, magnesia
132'36 lb. potash
14°32 lb, soda
13'10 lb. phosphorie acid
But, besides the actual weight of material that
can be. obtained for weighing at any one time,
there is continuous fall of leaf from the trailing
stems, as the lower ones are smothered by the
new growth. This increases steadily with the
age of plant, so that after a year’s growth the
above figures could be at least doubled, and the
humus gained would amount to 8,000 to 10,000 1b.
per acre.
The plant dies down after flowering and seed-
ing, when the land should be cleaned and another
crop grown if desirable. Although it is sug-
gested to grow these crops to increase the humus
and water-holding capacity of the soil, and at
the same time to smother other weeds, and pro-
tect the soil from sun and rain, they are not in-
variably applicable, since, wnless they are known
to grow faster than other weeds in the district,
they will be useless for the prevention of the
growth of stronger grasses, and may themselves
be smothered out.

GERMANS PRODUCE AN EDIBLE
FAT FROM GOPRA.,
Washington, Feb. 12, 1909.—[The success of a
number of German manufacturers in producing
edible fats from copra, the meat of the coconut,
has aroused much interest in the United States
and has brought to the Bureau of Manufactures
a number of requests for dotailed information on
the subject. ice-Consul Joseph H. Leute,
of Mannheim, by instructions received from the
bureau, has forwarded a report which our
correspondent is enabled to present below :—]
Perhaps not the least of the renowned excel-
lence of German cooking is due to the use of good
baking and frying fats. Retined lard, so com-
mon in the United States, is little used here,
oeine disdained by the well-to-do. The poorer
eople use cheap varieties of it, which the
utchers and sausage manufacturers usually
make, The better classes use beef fat, goose
grease and butter, some families (and these not
of the wealthy class either) going so far as to use
butter for everything. However, butter and
other animal fats have been soaring in price,
along with other articles of food, and so manu-
factured fats have been coming on the market.
The German law is fairly strict in the matter of
foodstufis and their quality, so that really poor
fats cannot be sold. One Mannheim firm has
brought out “ palmin,” a cooking and baking fat
of purity and excellence. Its sale has enormously
increased and an export trade is developing.
Palmin is a hard, snow-white vegetablo fat of
practically 100 per cent. purity. While the
process of its manufacture was originally secret,
so many factories manufacturing similiar lines
have recently sprung up in Germany that it can
no longer be so considered. Palmin is made
from ‘‘copra,” which is simply the dried and
smoked meat of coconuts. Heretofore the bulk
of the copra used has come from Ceylon. The
Mannheim firm is now contemplating erecting a
factory where it will prepare the meat itself,
which will mean, among other things, even more
scrupulous cleanliness than before. This copra
_is treated with high-pressure steam to remove
all oils, water, etc. After the removal of the
impurities and water the fat secured is 100 per
cent. pure and only slight treatment is then
needed to make the finished product.
GROWTH OF THE BUSINESS,
The Mannheim factory started with an output
of about 2,000 pounds a day, or 700,000 pounds
a year, and a working force of 50 men. The
output now is between 20,000,000 and 25,000,000
pounds a year, and the working force has grown
to about 80 men and 140 girls at Mannheim and
40 men at a branch factory at Williamsburg.
The product has found such favour that the
factory can scarcely keep up with the demand,
The main office will soon be removed to Ham-
burg and will have a force of 100 men. The new
factory to be erected there will be used mainly
for manufacturing copra.
The following local prices for cooking fats
will make apparent the reasons for the growth
of the factory and of the sale of its peeduates

Palmin is neatly packed in oiled paper in 3, 1,
5 and 10-pound blocks, and owing to its hardness
and snow-white colour, makes an appetising fat,
being also of great fat purity, while none of the
other fats contain less than 7 to 10 per cent of
water, Having such success with Palmin, the
Company has put onthe market a substitute
for butter called ‘“‘palmona.” Contrary to the
methods used for introducing palmin, which was
pushed with real American advertising vim,
palmona has not been advertised at all. It has,
however enjoyed such immediate popularity that
THE ENTIRE OUTPUT OF THE FACTORY IS USUALLY
SOLD FAR IN ADVANCE,
Owing to its lack of water and oils, palmin is
very hard and cannot bespread. Palmona being
manufactured from the pure palmin, the latter
had to be worked until enough water was taken
up to make it pliable. As a matter of fact,
palmin will not take up water at all, and the
little spheres of fat remain absolutely unequal-
ised and can be seen on examining palmona
closely. They likewise do not take up the colour
of the egg yolks, etc., which are added to impart
a resemblance to butter. Palmona sells for 224
cents a pound, while table butter costs 35 cents.
The factory guarantees its freshness for a period
of three weeks, for which purpose it has pur-
chased specially built refrigerator cars; the
plan is also to establish branch factories,
first in distant parts of the home market
and then in foreign countries. The ordinary
refrigerator cars of the state railways were
found inefficient, one reason being that
they have sliding doors which do not shut
tightly. ‘Therefore specially constructed cars
with folding doors, etc., were built by 2 German
car-building firm for shipping palmin. The cars
were not bought outright, but leased or rented
to the palmin company at about $2,000 a year,
the constructing company carrying all risks and
insurance. At the end of five years the car be-
comes the property of the palmin company. At
present they have some twelve cars running and
eight more being built. The state railways
charge only the freight rates on loaded cars, re-
turning empty cars free of charge. The cars
naturally also have a considerable value as
advertisement,
While the greater part of the company’s pro-
duct is sold in Germany, it has a growing
foreign trade, the largest part of which is with
South Africa. Most of the latter business is
handled through London, because of the local
feeling, which will eventually lead to the estab-
lishment of a branch house in England and
thus further increase the demand. As other
markets are created, this will also be the pro-
cedure in countries with a high protective tariff,

‘‘ILLUK GRASS.’’
Colombo, March 12th.
Dean Sin,—With respect to the question
asked in one of your previous issues as to the
best and cheapest way to getrid of ‘‘illuk”
grass, I should advise your enquirer to try the
following plan which I have always found cheap
and effective :——‘‘ Provide your weeders with
sharp-edged weeding currandies and let them
chip the ‘illuk’ grass down level with the
ground and repeat this again and again as
soon as, say, 3 inches of growth makes its ap-
pearance.” In thres months or so, the roots
will all die off under ground. I have tried
forking the roots out and many other remedies,
but the chipping back process is the cheapest
and surest way to eradicate this most trouble-
some grass.—Yours faithfully, ch
Golua Pokuna, Katunayaka, March 24th.
Dear Sir,—The Acting Director, Royal Bota-
nic Gardens, Peradeniya, to whom specimens of
Maduvel, or Kirimadu, and Pupula were sent,
at his request, for identification, kindly informs
me that the botanical names of these plants are
Lpomea cymosa and Vernonia Zeylanica respec-
tively.—Yours faithfully,

THE ALGAROBA TREE IN
HAWAIL.
A Prigst’s INVALUABLE GIFT.
Honolulu, Hawaii, Jan. 5,—Almost every
visitor to Honolulu has probably had his atten-
tion called to a gnarled and twisted old tree,
with top broken cor cut away some twenty feet
above the ground, which stands partly upon the
sidewalk and partly within the grounds of the
Roman Catholic Cathedral on Fort street, a few
blocks from the waterfront. A square wooden
sign nailed to the ronal trunk, just below the
mass of straggling, decrepit branches which
cast a poor shade over the dusty street, bears
the following inscription in gold letters :—
First ALGAROBA TREE
of the HAWAIIAN ISLANDS
Imported and Planted in 1837
By FATHER BACHELOT.
Founder of the R. C. MISSION.
Father Bachelot, the pioneer French priest
who established the Catholic mission in Hono-
lulu in 1827, probably had but little idea of the
service which he was rendering the Hawaiian
Islands when on his return from a trip to Cali-
fornia ten years later he brought with him the
little algaroba seedling and planted it in the
corner of the mission grounds, then in the out-
skirts of the village of Honolulu. But from that
one tree have all the islands of the group become
heavily forested with one of the most valuable
ofall the trees at present in the territory, It
has clothed in verdure thousands of acres
which from lack of water were utterly barren.
The Algaroba (Prosonis juliflora) is a native of
the arid South-western section of the United
States, where it is generally known as Mesquite,
although differing from the mesquite of Texas
and New Mexico. In Hawaii it seems to have
The Supplement to the Tropical Agriculturist
found even more congenial conditions than in
its native habitat, and the trees often attain a
height of fifty or sixty feet, and a girth of six
feet or more. Beside the value of the hard dur-
able wood for building purposes, fence posts and
fuel, it hasa much greater valueasa feed for
stock, and it is torthis purpose that it is most
valued in Hawaii. Cattle and horses eat the
foliage readily, as well as the sweet seed pods,
and thousands of head of cattle have no other
feed the year round. The large honey industry of
the islands has been made possible largely from
the splendid pasturage the bees fina in the alga-
roba blossoms.—-At the present time the econo-
mic value of the algaroba is attracting much at-
tention. Lt is predicted that within a short time
the very abundant seed pods of the tree willsup-
ply a considerable part of the horse and cattle
feed which is now imported in the form of barley,
corn, oats, etc. These pods contain by weight
almost fifty per cent of sugar, which causes it to
be greedily eaten by stock, while the seeds are
rich in protein, having about the same food
value as flax seed. Heretofore but a small part of
these seeds has been available for food, owing to
the hard covering which resists digestion unless
itis broken. The pods could not be ground owing
to their mucilaginous character which caused the
gumming up of ordinary milling machinery, A
Honoluluinventor has just devised avery simple
machine which has proven admirably adapted
for the work, however, and it is probable that it
will soon come into very general use. Dr E V
Wilcox, director of the U.S. Agricultural Experi-
ment Station, estimates that land in algaroba
should produce not less than $100 per acre in
feed, basing the price of the product at about
half of the cost of imported forage.
Experiments in making alcohol from the
algaroba pods, show that it will yield about 500
pounds of alcohol per ton ; while the tood value
of the seeds is not affected by the distilling pro-
cess.— WiLL J Cooper.—Hawaii Promotion Com-

BRITISH GUIANA RUBBER OUTPUT,
Reports from British Guiana show that the out-
put of balata for the year was 973,269 1b., as against
634,242 lb. last year. The rubber produced
was also greater, 6,873 lb. having been gathered
as against 2,563 lb. The price of balata was
fairly maintained, while that of rubber fell;
the value of the latter is, however, again going
up. The palo colorado or cucuracho tree of
Mexico, claimed asa new source of rubber supply,
is stated to possess a sap which yields over
33 1-3 per cent of pure caoutchouc, It grows
abundantly in the Pacific slopes of Sierra Madre
Mountains, at an elevation of from 2,500 ft. to
4,000 ft. above sea level, The tree reaches an
average height of 24 ft., and is from 8 in. to 14
in. in diameter. The tree is tapped in the same
manner as the true rubber tree, and when
tapped gives a thick white sap, which becomes
semi-solid when exposed to the air. When
tapped the larger trees produce over 2 lb. per
day, but after one or two days’ run the cut has
to be closed with clay, so as to allow the tree
to regain its vitality.—H, & C. Moil, Feb, 12,

BITINGA RUBBER.
FROM “ RAPHIONACME UTILIS.”
Considerable interest has been aroused re-
cently by the discovery in Portuguese West
Africa of a plant, bearing various native names,
such as ‘‘ bitinga,” ‘‘ ecanda”’ and *‘ marianga,”
the tuberous roots of which contain a rubber-
yielding latex. Several specimens of therubber
and of the roots of the plant from which it is
obtained have been received at the Imperial
Institute from the Mozambique Company. The
samples of rubber consisted of three roughly
cylindrical pieces, which differed considerably
in quality owing tc the inclusion of varying
amounts of impurities. The cleanest specimen,
_which, however,contained an appreciable ainount
of impurity, consisted of pale yellowish- brown
rubber exhibiting good elasticity and tenacity.
The other two pieces were darker in colour ; one
of them contained a considerable quantity of
vegetable impurity, whilst the other wasimpreg-
nated with fine sand. In both cases, however,
the physical properties of the rubber were fairly
good. The light-coloured rubber was chosen for
analysis as more likely to represent a well-pre-
pared product; this gave the following results:—

These results indicate that the rubber would
be of good quality, so far as chemical composition
is concerned, if it were not for the presence of
the large amount of insoluble impurity which
considerably reduces the precontage of true
caoutchouc. The amount of resin is somewhat
high, but the percentage of proteid is exception-
ally low. A portion of this sample was valued by
commercial expertsat Is, to 1s.3d. per |b., but they
stated that the rubber, if clean, should be worth
3s. per lb., or more, as compared with fine hard
Para rubber at 4s. 1Ud. per 1b, on the same date.
Roots.
A number of the tuberous roots of the plant
were also received and submitted to examination.
The tubers are turnip-rhaped, and vary up to
5°5 inches in diameter and 4 inches in height.
They are covered with a dark brown scaly bark.
Many of the roots had decomposed more or less
during transit, but a number were still sound,
and yielded latex quite freely on incision.
Two samples of the fresher roots with un-
broken bark were selected for analysis; specimen
A was a single large tuber weighing about 6
ounces, whilst B consisted of two smaller
tubers which together were approximately equal
in weight to A, Tho results of the examination
were as follows :—

Rubber (on dry roots) 11°6 3

The yield of rubber from the tubers as received
is therefore very low (1°0 to 1°5 per cent) owing
to the large amount of water which they contain,
and as these tubers must have dried consider-
ably during transit, the freshly-collected roots
will probably furnish much less than the
figures recorded above, Tho acreage yield
of rubber from the dry material is however
fairly high, viz. 10°5 per cent.
IDENTIFICATION Or THE Biringa PLANr,
Specimens of the ‘‘ Bitinga’’ roots were for-
warded .to Kew by the Mozambique Company
with a view to the identification of the plant, and
flowering specimens were obtained in March of
thisyear. The plant proves to be a new species
of Raphionacme of the natural order Asclepia-
daceze and has been named Laphionacme utilis
Brown and Stapf....[t is probable that the Bi-
tinga plant thus identified is identical with the
‘* Heanda” or ‘‘ Marianga ” plant discovered by
Professor Geraldes, during a journey to the
Upper Zambesi, in 1904-05, According to this
author the Ecanda or Marianga plantoccurs in
the sandy treeless plains (anharas) of Bailunde
and Bihé and on the sandy steppes between the
rivers Quanza and “Zambesi, at an altitude of
4,000 to 5,000 feet. The natives in these
districts prepare rubber from the roots by
cutting them into slices, which are then spread
on the ground and exposed to the sun, whereby
the exuded latex is coagulated. The rubber thus
formed is rolled into small cylindrical pieces,
about 5 inches long and 2 inchin diameter. The
rubber so prepared is stated to be of good ap-
pearance, but it usually contains considerable
quantities of earthy impurity; thus, one sample
examined contained only 45'8 rer cent. of true
rubber, and 51°4 per cent of impurities.
Professor Geraldes found that the most prac-
ticable method of obtaining rubber from the
fresh roots was to cut them into pieces and sub-
ject the latter to pressure. In this way the
latex, much diluted with the sap of the roots,
was obtained. The yield of liquid on expression
amounted to about 77 per cent, of the weight of
fresh roots used. From this liquid, the rubber
can be prepared either by heating it or by ex-
posing it to the air. The maximum yield of rub-
ber obtained by Professor Geraldes in his
experiments was a little less than 0°5 per cent.
from the fresh roots, which is less than half the
amount found in the tubers received at the Im-
perial Institute.
It isimpossible, until further particulars are
available, to express any opinion regarding the
probable value of the Bitinga plant as acom-
mercial source of rubber, Definite information
is required as to (1) tho rate of growth of the
plant; (2) the age at which the tubers can best
be utilised for the preparation of rubber; (3)
the weight of fresh roots which can be obtained
per acre ; (4) the average yield of rubber; and (5)
the best method of obtaining the rubber from
the roots. It is understood that the Mozambique
Company is vonducting experiments in East
Africa in order to determine these points, and
to ascertain whether the plant is likely to repay
cultivation.—Imperial Institute Bulletin No, 4 of

RICE PRODUCTION IN KOREA.
Consul-General Thomas Sammons, of Soul,
describesthe progress and extent of the culti-
vation of rice in Korea and the importance and
value of the industry to that country and to
Japan :—American rice-cleaning machinery is
being extensively introduced in Korea and _ in-
variably gives the best possible satisfaction.
The machines are so constructed that broken or
worn-out parts can be replaced without difti-
culty. In construction these machines are
simple and the natives readily learn to operate
them. The English type of rice-cleaning machi-
nery is not utilised, although anumber of Japa-
nese machines are being sold in the Korean mar-
ket. An idea of the extent of the rice industry
of Korea may be had from estimates of the
annual vield as based partially on the total pro-
duction in Japan. Japan’s yield 1s placed at
approximately 14,800,000,000 lbs., and on a basis
of 1 koku of 320 Ibs,, or five bushels to each per-
son, this aggregate would supply more than
46,000,000 people. Assuming that Korea has
approximately 10,000,000 population, its annual
rice crop would amount to 3,200,000,000 Ibs., 64
per cent. having been exported in 1907. Korean
rice culture is carried on almost wholly by hand
and itis not probable that the hand methods
will ever make way for the American seeder,
self-binding harvester or steam thrasher, The
Korean farms are all small and the present
native product is higher in yield to the acreage
than is the American rice. The cheap labour of
Korea also permits of methods which the labour
condition in America would render prohibitive.

FIBRE CONGRESS AT SOURABAYA
iN 1910.
According to a notice issued at Sourabaya
(Java) on 25th February, with a view to pro-
moting the cultivation of fibre-producing plants,
the ‘’Nederlandsch-Indisch Landbouw Syndi-
caat” has decided to hold, at Sourabaya, Java,
Netherlands East-india, in October, 1919, a
Congress, combined with an Exhibition of
fibre producing plants, of the fibres pro-
duced therefrom and of the machinery used
in the preparation of same. During the Con-
gress, the cultivation and preparation of the
raw fibre, both mechanically and manually, will
be discussed. The extraction, preparation for
market and packing of the fibre will, as far as
possible, be demonstrated. Various prizes
(medals, diplomas and money) will be offered
for machinery working fora suflicient time du-
ring the covgress, awarded by a Committee of
impartial experts. The expenses will be de-
frayed by the Syndicate, enabled to do so by a
liberal grant from the Netherlands Indian
Government and _ substantial contributions.
With the Director of Agriculture a Committee
has been formed to prepare and carry out the
scheme; gentlemen in Holland have been re-
quested to form a Sub-Committee there. Special
attention will be given to the following, viz :—
The Supplement to the Tropical Agriculturist
1. AGAVE FIBRE,—the cultivation of which is spreadin
so Jatgely and which is specially adapted for dry tropica’
countries.
_2. MANILA HEmpP,—also a fibrous plant fit for eultiva-
tion ona large scale and which produces a profitable crop
in the moister districts of tropical countries,
3, JUTE AND JUTE SUBSTITUTES.—Of importance in all
tropical countries, seeing that a large part of the packing
material necessary for other produce is made therefrom.
_A detailed programme will shortly be pub-
lished. The preliminary notice is signed b
A. Paets Tot Gansoyen, President of the syndi-
cate and D. J. R. Putman Cramer, Secretary,
GERMANY’S WAR ON MOSQUITOES.
The German colonies in East Africa and else-
where have their mosquito problems to solve. This
has led the Colonia) Officein Berlin to take up the
matter with the Director of the Fisheries Station
at Biebrich, Germany. Mr. Bartmann,as Director
has been experimenting in the way of securing
some solution of the mosquito problem during
the last fourteen years. He now states that tho
most reliable method of mosquito extermination
in stagnant waters is by growing therein various
kinds of the semi-tropical plant called arzolla.
His numerous and ever successful experiments
haveled the Colonial Office to ask him for fur-
ther experimentation at the Institute for Tropical
Hygiene at Hamburg, where Director Bartmann
will have the use of the state botanic institute
for propagating the arzolla plants. Germany has,
however, a malarial station at Wilhelmhaven and
hundreds of cases have occurred there, the terri-
tory being full of stagnant waters and swamps
infested with mosquitoes. The proximity of the
sea and the unusually cool temperature of the
summer of 1907 had an unfavourable influence
upon the growth of the arzolla plant. 1t, how-
ever, covered the experimental waters in a short
time with a layer of vegetation over two inches
thick, which suffocated all of the mosquito larvee
below and _ prevented the living insects from de-
positing their eggs inthe water. A final report
will soon be made in regard to the experiments.
It is stated that strictly scientific and practical
proof have been made in the laboratories, A
covering of vegetation over the surface of waters
so close as to prevent the mosquito larve from
reaching the air and to prevent the mosquitves
from laying their eggs on the water, would seem
to us Impossible, and yet the data comes from
Consular Reports from Germany which seem to
demonstrate not only the possibility of the fact
but its actual realisation in given instances.
RHODESIAN RUBBER.

sale of 27 bags (just over 12 cwt of rubber) re-
cently received from North-Hastern Rhodesia,
The rubber realised from 4s 24d to 4s 23d iv

brokers remark thatthe market can take con-
siderable quantities of rubber of such a good
quality, which will be highly encouraging news
to Rhodesian planters.—India Rubber Journal,

RUBBER CULTIVATION IN
MALABAR.
We have just received a copy of a very intor-
esting report on the rubber trees to be found
growing at Nilambur and Calicut, in South
Malabar, which was written by Mr KL Proud-
lock when he was Curator ot the Government
Botanic Gardensand Parks on the Nilgiris, and
printed last year. It describes the investiga-
tions in connection with rubber trees in Malabar
carried out by Mr Proudlock in January, 1903.
Whenit was written is not stated, but it has
evidently been inexistence some years as it is
referred to in Mr Proudlock’s Annual Report for
1906-07 ; it was printed at the Government Press
in 1908, and it has only just been issued to the
public. 1t comprises the only real effort on
the part of the Government to collect into one
volume information regarding the 1ubber trees
introduced at various times into Southern India
from foreign countries during the last 30 years.
It seems certain from the documentary evi-
dence now available that the idea of introducing
American rubber trees into India originated
with Sir Clements Markham, forin a book en-
titled ‘‘ Peruvian Bark,” which he published in
1880, he wrote :—
“ In 1870 I came to the conclusion that it was necessary
to do for the India rubber or caoutchouc-yielding trees what
had already been done with such happy results for cin-
chona trees,”
Mr Proudlock briefly describes the introduc-
tion of Para rubber (Hevea Brasiliensis) into
India, Ceylon and Burma through the agency of
the Royal Botanic Gardens, Kew, which inter-
esting story has already been told in our columns,
It is not necessary here, therefore, to do more
than state that of the Malabar trees on which
Mr Proudlock specially reported 28 were re-
ceived from the Royal Botanic Gardens, Pera-
deniya, and planted out at Nilambur in June,
1879, and three more were received from Mr T
J Ferguson, of Calicut and planted out there in
1886. Further experiments were conducted with
Para, Ceara, and Castilloa rubber trees at
Plantation House, Calicut, and at Punur by
Mr T J Ferguson on behalf of the Govern-
ment, through whese agency he was sup-
plied with seeds and plants of these species
from April, 1883, to September, 1885. The
trees at Nilambur were left to the tender
mercies of the Forest Department officials, under
whose charge they made excellent growth for
the first few years. Then arose, apparently, a
generation which knew not the possibilities of
rubber trees, which were allowed to be over-
shadowed by teak, mahogany and other trees
dearer by far to the heart of the Forest official.
Mr. Proudlock quotes the views expressed by
two of these oflicials which demonstrate the
great mistake made by the Government in trust-
ing important experiments of this nature to
gentlemen who took no particular interest in
them. One of these, Mr. P M Lushington, in his
report dated the 2nd March, 1895, describes the
TAPPING OPERATIONS CONDUCTED IN 1886-87
AND AGAIN IN 1895,
as a result of which 100 trees yielded 10 1b. of
rubber ; and as this was not worth much more
than a similar number of rupees, he said that the
experiment must be considered to have failed
399
froma financial point of view. In any case, he
added, these trees were much out of place ina
teak plantation, and a proposition had been
made to cut them,out and plant the area with
teak. Fortunately, this was not done though
most of the rubber trees, introduced by the Gov-
ernment at great cost 16 years before, were
gradually allowed to succumb. The experimental
cultivation of rubber plants through private
agency had been ordered to be discontinued ten
ears before, and the adverse opinions referred
to obtained such wide publicity, that up to
within the last few years the majority of the
planters of this Presidency were deterred from
taking up what, Mr Prondlock says, “is now
proved beyond all doubt to be a highly remu-
nerative cultivation.”
As aresult of his tours in 1903 and subse—
quently, Mr Proudlock obtained a very favou-
rable impression of the exceeding suitability of
the belt of coastal country which lies between
the seaand the foot of the Western Ghauts,
both as regards climate and soil, for rubber-cul-
tivation on an extensive scale. This conclusion
it must be borne in mind, was arrived at durin
the first few years’ experiments that were car-
ried out with these trees, both by Government
officials and private persons qualified toform an
opinion on the subject ; and that it is widely
held today is evident from the thousands of
acres that are being cultivated with rubber
today wherever land can be obtained from the
Malabar to Southern Travancore, Mr Proudlock
also found the trees he tapped to yield latex
freely and of excellent quality. He obtained
1 LB. 5 028, FROM ONE PARA TREE AT NILAMBUR
IN JANUARY, 1903,
and nothing, he says, could be more satisfactory
than the yield from this particular tree, which
completely disproves the repeated inferences
contained in the Forest Department Reports
that the trees at Nilambur would not yield
sufficient rubber to pay. As a matter of fact,
had these trees yielded poorly, it would no$ have
been surprising, for, owing to having been
allowed to growunder too much shade, and too
close together, they were ‘‘rather spindly and
had poor crowns.” Besides, as Mr Proudlock
explains, proper methods of tapping were not
employed, as they were neither known nor
understood at that time; nor was the tapping
carried out regularly in a systematic manner by
a trained staff under proper supervision, as it
must be if rubber cultivation is to be made
to pay.
We may confidently affirm with Mr Proudlock
that no further arguments appear to be neces-
sary to prove that the mature Para trees at
Nilambur are capable of yielding rubber quite
as good, both in quantity and in quality, as
trees of the same species will yield in any part
of the Hastern Hemisphere; and that the
Nilambur country, as shown in the photographs,
a number of which are published with the Re-
port, contains some of the finest sites in Southern
India for rubber cultivation, especially for
Para rubber, The failure of the various Forest
officials concerned to gauge the true value of
the latter must be excused on the score that the
400
acclimatisation of rubber trees and such ex-
otics does not come properly within the scope
of their work. As Mr Cherry, Conservator of
forests, Southern Circle, wrote to the Govern-
ment in this connection in 1898 :—
“Tt is very difficult to get subordinates to take conti-
nuous action in these matters, and District Forest Officers
have had their hands so full of work (especially settiement
and survey of Reserves), that such experiments are apt
to be lost sight of.”
This admission points to the advisability of
appointing a special officer, as recommended by
Mr Proudlock, to «teal solely with the direction
of the cultivation of exotics throughout the
Presidency. The result of the present policy is
well exemplified by the present position of
rubber-planting, in which, despite the fact that
the Government of India were the first to appre-
ciate its possibilities, the planters of Southern
India are now far behind those of Ceylon, the
Straits Settlements and the Federated Malay
States. The Government of Madras have now
published Mr Proudlock’s illuminating Report,
anclitis to be hoped it will obtain an extensive
sale or circulation for it corrects a number of
erroneous impressions for the dissemination of
which the Government are entirely to blame,

MANURING TEA, CLEAN WEEDING, &c.
A recent enquiry of Mr. Hughes as to his
‘* Basic Super-phosphate ” has produced some
interesting information, dated March 8th. A lec-
ture noticed in an Inverness paper, he says, is one
of a series by the representative of the Basic
slag people who apparently consider its useful-
ness, as a manure on soils deficient in lime, has
not been yet fully realised. Unfortunately, Mr.
Cox does not recognise that in the selection of
slag, the composition of the soil ought to be
considered—the consequence being that it is
occasionally applied to soils quite unsuitable, to
the great loss of the farmer, who is naturally
disgusted and says that slag js no good for his
land, and thereby influences his neighbours
againstitsuse. I refer to this point more fully in
the enclosed reprint from Farm and Home :—
The new manure is intended to occupy an inter-
mediate position between acid superphosphate
and alkaline slag, and to be applied for inter-
mediate descriptions of soil. 1tis not intended to
supersede the use of superphosphate upon good
arable land containing plenty of lime, nor is it
intended to take the place of well-ground slag
upon sour grass land, damp, heavy clay or rich
vegetable soils; but it is specially intended for
soils deficient in lime, such as light clay, gravel,
granite and sandy soils, the united acreage of
which represent such a large proportion of the
cultivated area of the United Kingdom.
For the reasons given in the article I am quite
sure that if used in equal quantities in Ceylon
soils Basic superphosphate (which consists of su-
perphosphate neutralised by quick-lime) would
prove far superior to the ordinary Basic slag,
which consists ofa hard fused rock, however finely
it may be ground. isee in regard to slag in
Ceylon one authority only recommends 1 cwt.
The Supplement to the Tropical Agriculturist
per acre for burying with the prunings: a quan-
tity totally inadequate to neutralise the acidity
attending the decay of green leaves buried in a
damp, stiff soil, Lam not surprised that fresh
lime. in a much larger quantity should have re-
placed the use of slag, which only contains ¥ to
3 per cent of free lime. As regards clean wee-
ding I should think that on steep faces it is by
no means desirable ; indeed, I should prefer to
leave such steep faces unplanted; but, being
planted, I should have gently sloping drains cut
at frequent intervals along the face filled or
partially filled with prunings for intercepting
the wash—the decomposed leaves being cleared
out from time to time and made into a com-
post, with lime and soil, for future application
in large holes between the trees and covered
over. On fairly flat land, clean weeding for tea
and partial weeding for rubber would, I think,
be desirable, I am interested to notice how Mr.
Bamber insists upon forking the surface as a
beneficial operation. You remember how 1
pointed out this in 1878: also recommended
ground coral being used in preference to caustic
lime, because I said that Ceylon soils wanted
lime, but being deficient also in organic matter,
the neutral coral lime would be more suitable
than the strongly caustic lime which would be
calculated to burn up the organic matter. Iam
surprised any one should recommend the caustic
lime as a general means of supplying lime to the
soil, though, if used with prunings, the caustic
lime would naturally be the more suitable.

A FrencoH Manvuat.—RvuBBER-MANURING :
CLosE PLANTING: DISTANCE BETWEEN THE TREES.
We have received from Messrs. Williams
and Norgate, for Mons. Augustin Chal-
lamel, the Paris publisher, a copy of the
latest work on rubber cultivation in Malaya by
Mons. ©. Mathieu, who has apparently had
lengthy and good planting experience in the
East. The book is well printed in large type on
good paper, and is in double parallel columns,
English and French. The Manual, we learn
from the preface, was first written in English,
the French text having been written afterwards,
with various additions and amplifications. The
author deals with his subject very fully and in
an interesting manner. He gives some advice
in his opening chapters to the young planter
coming out fresh to the East, and then plunges
into his subject, dealing with the selection of
land for a plantation and the laying of it out in
plantation and nurseries, with notes on the
selection of sites for bungalows, lines, hospital,
&c. Inchapter V the Manager’s bungalow is
discussed, with plans and details for construc-
ting the same and estimates of probable cost,
The numerous diagrams make this an informing
and useful chapter. Mons. Mathieu is insistent
on good surroundings and sanitary conditions
for the Superintendent and his employees, and
gives numerous hints on how to secure such
conditions. We quote the following ;—
and Magazine of the Ceylon Agricultural Society.
“Rrom the one of happy go-lucky amateurishness percei-
vable in some of the Rubber Companies of recent birth, it
would seem asif the management of an estate is, intheir
eyes, a matter of small concern, The little seed, which is
pat in the ground, is evident}, expected to do, by itself,
all the work of growing into fine tat trees, bulging with
milk, Wecan now understand how it is that estates of
1,000 acres to 1,500 acres of land, in great part tappable, of
land on which £150 to £189 of capital had been raised per
acre, areleftin the hands of an underpaid manager with
one assistant. To such, all that is here written is pure
fudge. ‘The past history of these countries is unfortunately
full of the dismal failures of such ill-conceivea ventures.
But there are also earnest workers, and they are many, who
do not trust to the sole aid of Providence and who know full
well, that huge undertakings such as we hear of, are not
to be brought to the paying stage by haphazard manage-
ment and that a good equipment is the first necessity
of success.”
The author then takes us very fully into the
subject of the Asiatic agricultural labourer, more
particularly the Chinese, Javanese and Tamil
classes. A chapter on lalang yrass concludes
the first part of the book.
In the second part he deals with the Hevea
tree itself, and its cultivation, The opening up of
the estate and ali the attendant operations of
roading and draining, etc., different kinds of
soils, nurseries, planting out, &c., carry one
through six interesting and informing chapters.
Then we get to ‘“‘ Field Work,” and the impor.
tant subject of distance in planting. On this
subject, still one under discussion in the last,
we make the following interesting extract :—
CLOSE PLANTING.—Close planting was generally adopted
on the older estates and most of the acreage under rubber
is planted at distances of 12 feet to 15 feet. Now, there are
very good reasons of economy for not giving a tree on an
estate more room than it absolutely requires for its normal
development: Having ascertained by experience, and by its
habits of growth, that the liberian coffee-tree, for instance,
can be brought to its full fruit-bearing capacity, on the
space enclosed in a circumference of 12 feet diameter, which
allows 290 trees to the acre, it would serve no purpose to
give it 13 feet, which allows only 239 trees as that would
mean a larger surface to keep clean, an extension of the
road and drainage system of the estate etc.; if would mean,
in fine, increased working expenses for smaller crops. There-
fore the trees should be allowed no more space than is ne-
cessary for them to give their fullcrop. But, under pretext
of economy, tosqueeze the trees in a space that will not
allow them t» attain their normal size, and thereby to re-
duce their future rubber-yielding capacity appears to me
ever more wasteful than the other way, besides involving
undue risks of disease to the plant. Practically, The limit
to the rubber-yielding capacity of the Hevea is reached
when there is no more bark left toincise on the nether 6
feet of trunk which is the easiest accessible part of the
tree, and that which yields the most latex (barring the roots).
Therefore, anything that tends to reduce the attainment of
girth, and thereby of bark, is unsound, and that is what
close planting at 10, 12, 15 feet comes to,
ONE REASON GIVEN FOR CLOSE-PLANTING
was thatit prevents branchiness, which it undoubtedly
does, and that the tree having already a marked tendency
to branchiness, this should be checked and thus, a higher
range secured for the future tapping of the tree. This was
anticipating the practice of high tapping, at present in
vogue on some estates. But I cannot look upon high tapping,
with its concomitants of ladders, unsteadiness in the work
of incision, lessened yield of latex, as anything but
a ‘“‘pis-aller.” It should not be an aim; an as
for the a4 to prevent branching, I may be allowed
torepeat whatI wrote some years back :—
“‘Considering that the first branching does not as a
rule begin before a height of 8 to 10 feet of the trunk ; con-
sidering, also, that it is an easy matter with the pruning
knife, to check any tendency to too early branching I
do not see the force of the objection to its branching, at a
height above the milk-yielding region, while I see a very
considerable advantage in securing as large a stem as
possible, affording a broader surface.”
In the light of experience gained since, these words re-
main true, and close-planting with a view to checking
branching, and obtaining a long tapping surface will soon
be considered as a heresy and a costly one. In fact, the
notion is already so far belated that the very reverse is now
ak
401
advocated by some writers who recommend topping the trees
to induce forking. Yet, close-planting is still practised on
some estates with the idea, when overcrowding takes
place, of thinning out, i.e. of felling a proportion, say one
out of two trees, after cropping them of al] the rubber they
can give.”
M. Mathieu has some interesting remarks to
make under this heading which we venture to
quote :—
In 1903 I wrote :—‘‘ Judging from the Hevea seen in these
parts, I would say that 15 to 18 feet interspace between
each tree would meet its requirements. This would give (15
by 15) 196 trees to the acre ina poorer soil and (18 by 18)
130 in a richer soil. In very rich soilssuch as are found in
parts of Sumatra and Borneo, I would probably adopt very
much wider planting, viz: 25 by 25 feet.” In the presence
however, of the ability of the tree to stand much heavier
tapping than was then thought prudent for the safety of the
tree, 1 must admitI now think those distances too small
for the reason that the heavier the tapping, the greater
the surface of the bark must be in order to be able to
apportion the incising, in such a way that the bark shall
have time to renew itself, between one tapping and the
next. Open planting undoubtedly favours increase of girth
and for that reason I recommend wider distances between
the trees. Of course, if we push mattersto extremes and
hold to the hardand fast rule that a tree should have all
the space its branch and root system can cover, we should
probably have to allow each tree 30 to 40 feet or more, since
the oldest trees we know of,30 years old already cover more
than that surface of spread,
The author advocates for Malaya 20 feet
between the trees. We know that manuring is
being done in various estates in Ceylon for the
three objects which M, Mathieu puts forward :
(1) Making up for soil exhaustion; (2) Giving
to the soil the constitutents it lacks; (3) Has-
tening growth by promoting increased activity
in the organs of nutrition, roots and leaves,
and thereby quickening the formation of wood.
Of burnt earth as a readily acquired manure
the author speaks highly, and ne thus describes
how it should be prepared :—
A gang of, say, 10 men should be put to this work for
one month during the period of driest weather. They col-
lect, withthe rake, allthe dead wood or fallen branches
and dried leaves or twigs, cut the rank grass and small
shrubs growing about and put all up, in heaps 4 feet high ;
then, with the changkol, they pare the top soil all round,
and collect it in their earth baskets; it is spread on the
heaps ; 3C basketfuls will suffice to cover one heap com-
pletely on allsides, The heaps then present the aspect of
earthen cones. Asmall opening is made below and fire is
applied to the dried leaves inside ; when the fire is well
on, which is seen by the smoke issuing from the sides of
the cone, the opening is completely closed, anda slow com-
bustion goes on inside during 2 or 3 days, after which the
heaps can be opened tocool, and the burnt earth applied
when wanted.
We do not know that the somewhat drastic
operation of root pruning Hevea trees has been
recommended by other authorities on rubber
cultivation, Butit is well worth referring to
what the author under review says on this point.
He remarks—and doubtless some of our readers
will be willing to give their opinions in these
columns on M, Mathieu’s statements :—
Cutting the roots of Hevea will sound as a heresy to
many, and so itis, as long as the roots, finding adequate
sustenance in the soil, are able to discharge their func-
tions of supplying the tree with the materials that go to
building it up. So long as these conditions last, the roots
keep on throwing out young feeders in every direction
ahead of them and, through them, drawing greedily the
food stored for them. When, however, the roots have
reached the limit of their hunting ground, their spread-
ing must cease; then, they coil up and form into tangled
masses through every inch of the ground until, space
lacking, they cease throwing out young feeders; their
texture hardens, becomes leathery and, from that time
their activity slackens, and growth also. At that time,
I have found that a partial and light cutting of roots,
at the extremity of their feeding ground, revives them
to a wonderful extent. The opening of the ground causes
moisture to penetrate deeper into the earth and the roots
strike, at an angle, lower down the soil into new layers;
402
and in place of the leathery, inert roots, thousands of
thread.like radicles are formed, which push their way
through the new space, and healthy growth is resumed. I
have applied this to Coffee trees, and I have gone the
length of putting the plow through acres and acres
of coconuts with the best results, and I see no reason
why the same effect should not be obtained with Hevea,
seeing the thickness of its root system and its tendency
to intermatting when confined from want of space. The
most efficient way to carry out pruning is to make a
trench, one foot deep, right through between the rows
of trees and 10 feet distant from the trunks, merely
turning the sod up to the side; this is best done with a
plow; and then, with a light cultivator 2 parallel trenches
one foot away on each side of the first but only 4 inches
deep so as not to injure the main roots. The work can
be done with the changkol, but the plow is much more
expeditious aud less costly, as it can easily do 4 to 5
acres in one day. Root-pruning is no innovation, and it
is practised almost universally on the large orange groves
of South California. In passing, I may also mention
another advantage of root-pruning, i. e., by turning over
the earth it exposes to the air and kills grubs and
fungoid growths, beside breaking up the galleries and nests
of termites,
The author then deals with the latex and
methods of tapping, coagulating, curing, &c.,
but want of space forbids us quoting any fur-
ther or extracting from a lot of interesting
matter in these chapters. The packing and
weighing of rubber are referred to, and the
charges on rubber exported are quoted from
the Ceylon Observer of March 12th, 1906, show-
ing the actual costs of shipping and selling
rubber in the London market ; but we under-
stand that owing to changes these must now
be slightly modified. The book concludes with
estimates of expenditure and returns of 3,000
acres of virgin land in the Malay Peninsula
planted in Para rubber, divided in three estates
of 1,000 acres each, the trees planted in quin-
cunx 20 feet by 17 feet 4 inches = 120 to the
acre ; these estimates go tothe 12th year; from
which period, the author says, the annual ex-
penditure will average $650,000, and the net
profit available for dividend will average a like
sum.
M. Mathieu has produced a most_interesting
and able book on the cultivation of Para Rubber
in Malaya, one which can be studied with ad-
vantage by all planters in the East, and the
photographs and diagrams in it add to the value
of a comprehensive study of the subject.

CEYLON BANANAS AT LEICESTER.
A fruiterer told me a month ago that the first
consignment of bananas from Colombo had just
reached Leicester. I bought some. They were
very good fruit.—Cor.
CrYLON BANANAS IN ENGLAND.
Mr,
March 25th,
Dear S1x,—The Ceylon bananas in England,
mentioned in your columns—I am inclined
to doubt that they were shipped as a busi-
ness transaction, and rather imagine they
were a surplus stock of fruits carried for use
during the voyage by some passenger boat.
More probably, however, the fruiterer was
trading on the fair name and fame of this
renowned island !
It is unlikely that any profitable trade in
bananas could be carried on between Ceylon
The Supplement to the Tropical Agriculturist
and England, in view of the peculiar facilities
available to the West Indies, and particularly
the Canaries.
Mr. Macmillan, Curator of the R B Gardens,
who has recently been making notes of the
tropical fruit at Covent Gardens, should be able
to tellus something interesting.—Yours truly,
Cc. D.

Peradeniya, April 7th.
Dear Si1r,—With reference to ‘‘C,D.”’’s letter
I can only support suggestion with regard to the
origin of the ‘‘Ceylon Bananas” at Leicester.
Commercially, of course, no bananas are imported
into Covent Garden (the fruit emporium of
England) from East of Suez, the English markets
being supplied by the Canary Islands and,
lately, by Jamaica.
On a recent visit to a fruitarian (which is
distinct from vegetarian) restaurant in London,
I tasted ‘‘ dried bananas,” which are made up in
the form of dried figs; they are peeled, halved,
and pressed in smal! wooden boxes, which hold
perhaps a dozen each. la this condition they
keep in good order for a comparatively long
time, which can by no means be said of the
usual shop bananas,
It is interesting to note the variety of uses to
which bananas are now adapted, such as
‘‘ banana flour ” (for bread), ‘‘ banana oats” (for
porridge), ‘‘ banana custard powder,” ‘‘ banana
cocoa,” ‘* banana cake,” ‘t blanc mange,” ‘‘ jelly
powders,” and ‘‘ banana health salts.” A Com-
pany has been formed in London recently under
the name of ‘‘ Banana Fruit Foods Company,”
which has for its object the preparation of such
substances as those named.—Yours faithfully,
H. F. MACMILLAN,
[We are much obliged to Mr H F Mac-
millan for his informing letter. We trust
experiments in dried bananas will be made
here, under Peradeniya or Agricultural Society
auspices, and’shipments sent home; the great
thing will be to. select the right kinds and see
they are properly desiccated, and packed. Even
then the ‘‘ Banana Fruit Foods Company,”
dealing in West Indian and Canaries bananas,
will probably have the pull.—A. M. & J. F.]

Dear §1r,—Mr Macmillan’s letter with re-
ference to bananas in London ought to settle
the question of the possibility of exportin
Ceylon fruit to England. The geographica
position of this Colony places it at a great
disadvantage when compared with the
Western tropics. Some time ago. banana
figs (Mafuta brand) reached Ceylon, but I
have not heard of the article—an excellent
preparation—lately. There is no reason why
this form of preserving our plantains should
not be carried on locally. Of. the other
banana preparations mentioned by Mr. Mac-
millan, Messrs. Miller & Co, of Colombo. kept
this in stock for some time; but, I believe,
gave up doing so as there was no demand
for them,—Yours faithfully,

TAPPING OF YOUNG AND OLD
RUBBER.
Kandy; March 27th.
Dear S1x,—I send you extract from a letter
dated 25th, received trom Mr J Anderson of
Bandarapola, which goes to support the conten-
tion of Mesers, Clayton, Beade & Stephens in
their summary arrived at in their last Report
to the Lanadron Rubber Estates :—‘'The qua-
lity of Rubber is not affected by the age ot the
tree that yields the latex.”
Mr Anderson gces further and states that
young Cearas don't go and die like old ones
when they are tapped.—Yours faithfully,
Ww. D.G.
(Extract referred. tv).
‘¢In supporting what you were writing about
in the Observer the other day 7¢ Rubber taken
from young trees, I enclose for your perusal
and return Report on and _ selling Contract
for a small case of Ceara Rubber I sent home
in December. This Rubber was taken from
trees, self-sown seedlings, only two to three
years.old, and at the sale it was said only two
or three marks got jd. higher. The proof of the
pudding is in the eating of it! I might also add
that young Cearas don’t go and die like old ones
when they are tapped.”

[‘“W, D. G,” returns to the charge fortified
with an expression of opinion by a_ planter,
whose views like his own carry weight. But if, as
Mr, Anderson says, the proof of the pudding is the
eating of it, how is it that the London brokers
— Messrs, Lewis & Peat particularly—year after
year advise the Ceylon planters to keep their
rubber from young trees separate from that
taken from mature trees? They have evidently
tested young rubber and found it wanting.
All that Mr. Anderson says may be perfectly
correct ; but the fact that manufacturers paid a
high price for immature rubber is not likely to
soften their resentment if they find subsequently
that it does not contain the nerve and resi-
liency necessary for the goods to which it is de-
voted. We should very much like to see definite
experiments carried out and the opinion of
manufacturers—whose taste in the matter it is
we have to consider—secured on the point.
Could not half-a-dozen of the well-known Ceylon
rubber estates prepare samples from trees 6 to 10
years old and. upward and from 3 to 4 years old
trees and submit them to some recognised autho-
rity to be tested ? his would satisfactorily
settle—once and for all—a very important point, ]
403
THE NEW TAPPING SYSTEM.
A REPLY TO CRITICISMS.
The chief indictment which has been levelled
against this system is, of-course, that it encou-
rages the tapping of immature trees, and that,
in consequence, during the next few yearsa
large quantity of inferior rubber will besent into
the market from Ceylon with, possibly, disas-
trous results to the reputation of the plantation
article. While it is pointed out that no one is
bound to use the system for this purpose, and
that the question of the age at which their
trees shall be tapped remains a matter
for the proprietors, at the same time the
claim made in the first circular issued,
namely, that the system will enable trees to
be profitably tapped at three years old, is ad-
hered to. It is one that is made on the grounds
both thata remunerative return can be obtained
from tapping three-year old trees, and that the
rubber is not inferior. Owing to the fact that
the latex is obtained, not by wound response,
as was the case under the old method, but by a
steady natural draining of the tree, it is asserted
that the product of the three-year old tree is
equal in quality to that of the five-year old tree
under the old system. This is shown by the fact,
borne out by repeated experiment, that a quan-
tity of latex taken out of the tree by the new
system yields a considerably larger percentage
of dry rubber than the same quantity of latex
drawn by means of paring in the old fashion.
The same quantity of latex is yielded by
both systems, but it is found that the
latex obtained by the new system yields
a greater amount of rubber. This, it is
pointed out, supports the contention that the
new system, bya natural process of draining,
ebtains the real latex in the cells, whereas by
wound response the tree was forced into yiel-
ding a liquid that contained very often mini:
mum amount of rubber. Moreover, by the old
process, portions of the tree were left entirely
untapped, whereas it can be easily demonstrated
that allthe latex is attracted by natural filtra-
tion to one spot and the tree thoroughly drained
by the Northway system. Sheets of rubber
obtained from three-year-old trees by the new
system have been compared with those made
from the latex of five-year old trees extracted
by paring, and, as faras they can be_ tested by
all available methods, there is no difference in
the quality. The colour of the three-year old
rubber is good and there is no sign of resin, In
the same way it is claimed that the latex of five:
year old trees is equal to that obtained by the
old process from 7-year-old trees, etc., the new
system, so to speak, adding 2 years to the age
of tho tree.
The next point is the injury done to the trees.
One important point that has been forgotten by
some of the critics is that it has not been claimed
for the system that it increases the yield of the
tree. What has been asserted is that it yields
the same amount of rubber in half the time and
at half the cost. This result, as has been already
pointed out, is achieved because the natural
method of draining the laticiferous cells has
been discovered, For instance, 58 mature
404
trees in 24 days by the new process gave 55
lb. of dry rubber, whereas under the old
system it took many more days—say about
55—to secure that quantity of rubber. The
fact that the bark is not stripped is, of course,
claimed as perhaps the greatest advantage of the
new process. The exact use of the latex in the
tree has never been, discovered, and not only Mr
Herbert Wright in his book but other experts
have asserted that the mere extraction of this
fluid, apart from the removal of bark, has not
been proved by exhaustive experiments to have
the least injurious effect on the health or vigour
ofthe tree. There have been plenty of warn-
ings, however, against too drastic or frequent
stripping of bark. Under the new system not
only are the resources of the tree which would
be expended in bark-renewal conserved, but
the cambium is protected by the bark re-
maining. In short it is claimed that the old
system was entirely wrong, and that by it
the minimum amount of rubber is obtained
by doing almost the maximum amount of
injury to the tree. It can be demonstrated
that large portions of the surface were not
drained at all, while other parts were probably
over-drained. The new system, with the mini-
mum amount of damage, extracts the maximum
amount of latex in the shortest time. The
visible difference in the character of the latex
(as is testified to by all who have seen thesystem)
is remarkable as compared with the old methods.
Experience has amply proved that, under the
old system, as you proceeded, the latex became
gradually weaker ; under the new method, having
obtained, say, t1b. of rubber per tree from five
year old trees, you leave the tree alone for two
months, though it has been found that in a short
time the tree is again full of latex.
Kandy, April 7th.
Dear Sik,—Tapping “virum que cano.” Who
is to be modern Virgil to immortalise the com-
ing war between Northway and his pricking pro-
cess of securing latex, backed by the mighty P.A.
errata aus Petch, the Peradeniya Mycologist?
he last circular issued by the Royal Botanic
Gardens, and fathered by Mr; T. Petch, sums
up his warnings as follows :—‘*The question of
burrs on the renewed bark deserves serious
attention ; indeed, it might justly be said that
this is more important than any disease at
present known in Hevea cultivation, because it
raises the question: whether in many cases it
will be possible to tap twice on the same area”
and ‘‘ the point should be considered most care-
fully before new systems of tapping based on the
use of the pricker are adopted, and it must be
remembered that two years atleast must elapse
before the effects of any system can be seen.”
This isa matter that affects the tree, not the
quality of the latex.—Yours truly, D
Il.
°
Neboda, April 7th.
Sir,—I am very glad to see so many places
taking up the new tapping system; but I do
hope that there will be no attempt to putin
large acreages till the system has been proved.
500 trees under the system for six weeks will
either set the superintendent swearing or re-
The Supplement to the Tropical Agriculturist
joicing. It must not be taken for granted that,
because acertain method is successful on one
estate, it will be equally successful on some other
estate, unless conditions are the same. I hope
I may be wrong, but I do not believe it is suit-
able to the general run of estates which are not
manured and more or less steep. You have to
be mighty careful with a tree which has only
the common soil to live on; but with the
manured tree, what can’t you do with it?
Some of the statements in your article some
days ago nearly take one’s breath away ; but
all I ask is that the system be properly tested
before a largenumber of treesare set aside for it;
and the more estates which try it, the more con-
clusive will be the decision one way or the other.
Pricking 1 have always had the greatest res-
pect for, because it would seem to be such a bark-
saver, and therefore, a saving on the energies of
the tree as compared with paring. I have, how-
ever, never been able to obtain the same satis-
factory results with the former as with the latter,
and am now inclined to somewhat, if not wholly,
discount this theory.
What appears to happen is that the tissue
round the wound made by the pricker decays,
and in healing is worked right out through the
bark. Some fow days after pricking these little
scabs can be prised out with a penknife. Then,
of course, the pricker having touched the cam-
bium, a small growth takes place which covers
the whole of the area of the wound where the
pricker actually found contact with thecambium.
Judging from the green or active appearance of
the tissues between the wounds, there would
appear to be considerable more claim on the
energies of the tree than would first appear.
I should say that my remarks do not in any
way apply tothe Malay States, where the con-
ditions prevailing I have only heard of. I have
no actual knowledge of them.—Yours, &c.,
G. H GOLLEDGE.
[The new system of tapping has so much to
commend it that most planters will be pre-
pared to take the risks of possibly injuring
their trees rather than waiting to see the
harmlessness of the system demonstrated by
time. Whether the new system of tapping,
based on the use of the pricker, will eventually
prove disastrous to the rubber tree or not,
remains to be proved; but should it unfortu
nately turn out to be injurious, the revelation
will bea bitter one to many. ‘‘W.D.G.” in a
letter elsewhere emphasises a warning uttered
by Mr. Petch on the point. Mr. G H Golledge
in his letter advocates caution in adopting the
new system until it is proved to be thoroughly
safe on the tree. And from his considerable a
rience his counsel will carry weight.-A.M.&J.F’.]
METHODS OF TAPPING HEVEA
BRASILIENSIS.
Peradeniya, April 9th.
Srz,—Since Circular No. 18 was passed for
publication, a pamphlet on Methods of Tap-
ping Hevea Brasiliensis by Dr. H Fitting has
come to hand. Lenclose a translation of that
part of it which relates to the use of the pricker.
and Magazine of the Oeylon Agricultural Society.
It will be observed that Dr. Fitting discusses
the question from quite a different standpoint
from that ot the circular. Dr. Fitting is one of
the foremost physiological botanists of the day.
To obviate confusion it may be noted that
‘* secondary cortex” is the cortex tapped by
the planter ; primary cortex only exists tem-
rorarily on green stems.
T, PETCH.
(Extract referred to),
‘‘And finally the important question, whether
the pricker should be used or not, must be
discussed. This instrument has no doubt cer-
tain advantages. In the first place, the cut with
the knife need not be made so deep into the
inner cortex, and, therefore, less cortex is cut
away: secondly, it isnot necessary to remove
strips of cortex so frequently, and therefore,
the tapping period can be prolonged, But the
planter must not delude himself into believing
that the pricker does not cut through all the
food channels in the cortex down to the cam-
bium, just asa deeper cut with the knife would
and thatthe worker with this instrument does
not all too easily destroy the cambium. ;
‘“ But the question whether the pricker is a
suitable instrument must be decided by the
influence it has upon the renewal of the cortex.
If no difference results between the use of the
pricker and a deeper cut with a knife. then
the pricker can be used without hesitation.
Since researches on this point have hitherto,
most strangely, not been instituted, {£ have
used, in the case of trees which were tapped
on the herring-bone system, the knife only, and
the combination of knife and pricker, on the
alternate tapping surfaces (i.e. the uppermost
tapping surface was tapped with the knife only,
the second with the knife and pricker, the third
with the knife only, etc., apparently it was
‘ half-herring-bone.’ Itwill be noted that this
method avoids any possible differences due to
the individuality of different trees.—T.P.)
‘1 have thoroughly examined microscopically
the cortex which was renewed in four to five
months. Where the pricker was not used, the
cortex, which does not differ from normal
secondary cortex, contained many latex vessels.
But the sections which were made through the
cortex on which the pricker had been used showed
quite a different structure. Wherever the teeth
had penetrated to the neighbourhood of the
cambium, the latter had constructed new cortex
with numerous groups of ‘stonecells’, but
without or almost without any latex vessels.
Where, on the other hand, the teoth of the
pricker had not penetrated through the inner
cortex, the latter contained latex vessels vither
irregularly arranged, or arranged in rows as in
normal secondary cortex. The whole surface of
the renewed cortex was uneven : everywhere
between the cuts of the pricker the cortical
tissue was swollen outwards. Thus it appears
that the cortex is renewed much more uniformly
on areas tapped with the knife alone than on
areas tapped with knife and pricker alternately.
The cortex in the former case must also be much
sooner re-tappable than in the latter. Further
observations, and comparison, under the micros-
cope, of sections of the renewed bark after a
longer interval than I could give, would deter-
405
mine without much difficulty how much longer
the ripening of the cortex takes after using the
pricker than after using the knife only, and
whether the greater quantity of latex which can
be obtained with the pricker compensates for
the longer resting period required. From these
considerations I believe that a note of warning
‘against the use of the pricker must be sounded.
The more so as I have often seen in plantations
that the teeth of the pricker were forced into
the wood. The pricker is obviously an instru-
ment which is out of place in rational estate
management. Rather should the cut be made
deeper, and imore cortex and bark removed in
tapping.”
FOR CUTS ON CACAO TREES.
Resin O1n as A Dressing.
Resin oil has lately been tried as an antiseptic
dressing for cuts and wounds on cacao trees at
Grenada, and is reported on very favourably by
estate owners and managers, and by the Agricul-
tural Superintendent of the island. Coal tar was
formerly the chief dressing used for wounds
caused by pruning or as the result of an acci-
dent, but it is stated that resin oil is superior
for the purpose. The Agricultural Superinten-
dent of Grenada (Mr R D Anstead, B.A.) re-
porting on the matter, mentions that the oil can
be applied easily and in a cleanly manner, and
it is noticed that the bark of the tree does not
shrink away at the edges of the wounds as much
as when tar is used; further, the new bark starts
into growth more quickly than when tar is the
antiseptic dressing applied. On cacao estates in
Grenada it isthe custom for a boy to follow close
behind the pruners, and to dress all the wounds
made on the trees. It has been found that the
best means of applying these dressings is by the
use of a paint brush, and in most cases brushes
of two or three different sizes are carried, so that
all the holes and crevices may be readily reached.
In this way the dressing is neatly and quickly
placed on the wound and there is less likelihood
of any being smeared on the surrounding bark.
This was a point to be borne in mind when tar
was the material in use, since it frequently
burned and damaged the bark; but no harmful
effects have been observed from the use of resin
oil. The only objection which has so far been
raised against the oil is that it is not easy to
recognise, without careful examination, which
wounds have been dressed, and which have not
yet received an application. This difficulty has
been got over, however, by mixing 1 part of tar
to 4 parts of oil. This mixture naturally pos-
sesses the advantages of the oil dressing, and,
owing tothe presence of the tar, wounds which
have been treated can be recognised at a glance,
Mr Anstead states that resin oil, or the mixture
of oil and tar mentioned, is rapidly coming into
use on the large estates at Grenada in place of
coal tar, and has also been adopted at the Botanic
Station, Experiment Station, and on the Ex-
periment Plots. At Grenada the oil is purchased
in cases containing 81-3 gallons at £1 5s. per
case, Itis stated that, when properly applied,
1 gallon of oil will go as far as 2 gallons of tar,
so that the former material is cheaper inthe
end,—W.I, Agricultural News, Feb, 20,

MADRAS EXPERIMENTAL PLANTING.
The annual general meeting of the Madras
Agri-horticultural Society was held this morning
at 7-30. From the Annual Report, we extract :—
PROGKESS AND CONDITION OF THE GARDEN.—
The plantation of Agave rigida var, Sisalana
is doing exceedingly well.
oled during the year and produced about 55,000
palbils, which were supplied to Mr Kirwan, in
accordance with the agreement entered into with
him. Suckers of this
AGAVE
were also supplied to him, At thetime of writing
70 more plants are poling and it is hoped that
they will produce about 160,000 bulbils. Twenty
seven plants attacked by-a fungus, specimens of
which were forwarded to the [Imperial Myco-
logist, Pusa, last year, have been removed. The
evtire plant was dug out, and pits six feet square
and two feet deep were dug, all the roots being
removed, as also the earth in which the roots
were growing. Extensive experiments with
Corton,
or any other field crops, cannot be made on ac-
count of the difficulty in watering, the water in
the wells being brackish. A few plants cf the
Rivers Sea Island cotton tree variety, have, how-
ever, been grown in the Nursery. Enquiries have
been made for this variety, and an order for 1 cwt.
of seed was forwarded to Sir Daniel Morris,
High Commissioner of Agriculture, West Indies.
Under the orders of Government all the cot-
ton seeds ordered from the West Indies have
to be fumigated before removal from the
Customs House. A large consignment of
CAMPHOR
seeds was again imported from Japan, but they
did not turn out well. What was distributed to
planters is reported to have failed to germinate.
The 4,000 camphor plants raised from a previous
supply have all been sold.
PARA KUBBER
seeds were also imported from Ceylon this year
and distributed. A small quantity was sown in
the gardens, but the percentage of germination
was not as good as in previous years. Only one
plant of Funtumia Elastica out of several raised
from seed is now alive, but itis feared that it
will not last through another long hot season.
The seeds were received from the Director,
Botanic Gardens, Old Calabar. New varieties of
MANICOBA RUBBER
seeds were kindly sent by the Director of the
Royal Botanic Gardens, Kew, in October last,
viz., 1,000 seeds of Manihot dichotoma ‘‘Jequie.”
1,000 seeds of Manihot piouhyensis ‘‘ Ramanso,”
These species are found growing in the States
of Bahia and Piauby and, according to the Kew
Bulletin, they can be tapped in tne third and
fourth year respectively. The seeds and plants
uf these species appear to travel well, the plants
sent by the Kew authorities to Calcutta, Ceylon,
Singapore, Java and other places having
reached their destinations in good condition.
The seed sent to this Society also arrived in
good order although they did not germinate
quite as satisfactory as was expected.
Plants of M. dichotomaand M, piauhyensis rai-
sed have been distributed, only a few that germi-
nated late being now available,-4, Mail. March 27.

(Eatracts from the Report upon the Botanical
and Agricultural Department, 1907.)
Intropuction.—During the year under review
the Department was enlarged by the establish-
ment of an Agricultural Station at Asuantsi in
the Central Province, This station has been
badly needed for some time and should doa
great deal to stimulate and supply the ever
increasing demand for Cacao and Rubber plants
in that province.
Starr, APPOINTMENTS, ETC.—Mr WS D Tud-
hope was appointed Director of Agriculture on
7th September. He left for Ceylon on the same
date to study the different economic plants of
that country with a view of introducing the
Ceylon methods into the Gold Coast pices
taking up his appointment in the Colony.......
ApurI Boranic GakpDENs.—The number of
plants distributed -during the year was the
largest on record but the distribution of seeds
was below that of last year. The total distri_-
bution was as follows :—

TRAVELLING.—A considerable amount of travel-
ling was donein the year. Mr Evans travelled
for nearly six months through the different cacao
producing districts in the Colony, giving advice
in planting, pruning, and the preparation of the
product for market. Several of the native staff
travelled through Ashantiand did valuable work
in the cacao and rubber-producing districts
RUBBER.
Funtomia Etastica (OrruntuM RuBBER).—
Several of this rubber tree growing in the Gar-
dens were tapped during the year, but we were
again unsuccessful in extracting rubber in pay-
ing quantities. Mr Evans carried out some ex-
periments on trees found growing in the forests
of Eastern Akim and extracted 54 oz, of. dry
rubber per tree in one tapping. He averaged the
age of the trees tapped at about 12 years. It
appears that the conditions and soil are against
the successful growing of this rubber tree at
Aburi, Samples of this rubber prepared by the
Bauhinia reticulata process mentioned in last
year’s report, also two other samples, one pre-
pared by a patent coagulating salt and the other
coagulated naturally were submitted to the
Director of the Imperial Institute who reported
on them as follows :—......
and Magazine of the Ceylon, Agricultural Society.
“RUNTUMIA RUBBER,—The four samples of Funtumia
rubber submitted are all of good quality and it will be sean
from the valuations obiained that consignments of similar
character would realise satisfactory prices. The two speci-
mens coagulated by means of an infusion of the leaves of
“ Bauhinia reticulata ” were not quite equal in appearance
to the other two samples and the price quoted tor them is
consequently a littlelower. They arg, however, superior in
chemical cowposition as they contain a much lower per-
centage of proteid and the amounts of resin are only very
slightly higher, The diminution in the amount of proteid
is probably due to the fact that when coagulation is brought
about by the use of an infusion of Bauhinia leaves the rub-
ber separates from a much larger volume of liquid thanin
the vthe cases with the result that the bulk of the proteid
remains in solution.”
‘Experiments conducted at the Imperial Institute
with the Bauhinia leaves which accompanied the rubber
specimens. show that a hot infusion of the leaves rapidly
and completely coagulates the latex of Funtumia elastica.
The infusion is acid and contains tannin, of which 8 per
cent is present in the dry leaves. It seems probable that
the tannin is the active coagulating agent as it has been
found that solutions of gallo-tannic acid and Of astringent
materials such as the pods of Acacia arabica exert a similar
action. In places where Bauhinia leaves are not readily
available it will therefore be possible to use some. other
astringent product for the same purpose.
‘This method of preparing Funtumia rubber appears to
promise very satisfactory results as it entirely obviates the
necessity of applying heat directly to the latex. The
experiments in the Gold Coast should therefore be con-
tinued with a view to the general adoption of the process.”
The trees of this rubber producing plant have
grown remarkably well this year. A further
sample of rubber prepared from these trees
was submitted to the Director of the Linperial
Institute who reported on it as follows:—......
COMMERCIAL VALUE.—“Probably from 2s to 3s 6d per lb.
in London but value uncertain.
REMARKS.—“ This sample of Ficus Vogelii rubber is of
rather better quality than two previous specimens from the
Gold Coast which have been examined at the Imperial Insti-
tute, (see reports dated 1st February and 28th August, 1906.)
The percentage of resin is lower and that of caoutchouc
correspondingly higher.
“The rubber furnished by this tree is of inferior quality
on account of the large percentage of resin which is usually
present. If, however, it can be prepared in commercial
quantities in the Gold Coast it would be well to forward a
trial consignment of about 561b. of the rubber for technical
trial, as was suggested in the report on rubbers from the
Gold Coast dated the 28th August, 1906.”—(S¢d) WyNDHAM
R-DUNSTAN. Dec. 17th, 1907.” [It had 60 per cent of Caout-
chouc.—ED. C.0.}
LANDOLPHIA OWARIENSIS (WHITE RUBBER
Vi1Nu).--Specimens of leaves and fruit of this
plant were collected in the Northern Territories
by a native assistant of the Department and he
reported it to be a root rubber and species of
Clitandra. The specimens collected by him
were sent to Kew and the authorities there de-
scribed it as Landolphia owariensis. It appears
that this plant forms a sort of underground stem
or rhizome in the open country. Samples of
rubber obtained at the same time were sub-
mitted to the Director of the Imperial Institute
who reported on them as follows :--......
COMMERCIAL VALUE.—‘‘The ‘biscuits’ were valued by
brokers at 3s to 3s 3d per lb. in this country, with fine hard
Para from Sonth America quoted at 3s S$d per lb. on the
same date. i :
REMARKS.—" This rubber is of good quality and deserves
further attention, It would be an advantage both in
preparing and packing the rubber for export if the biscuits
were made larger and thicker, say from } to 3-8 inch thick.
Consignments of similar quality would always be readily
saleable. Steps should be taken to procure complete
botanical specimens of the plant yielding this rubber for
determination.”
{This had 86°3 per cent. of caoutchouc.—Ep., C.0.]
ManrHor PrEcosA,—These trees have made
satisfactory progress during the year, some of
the largest are now 14 feet in height with a
girth of 7 inches at 3 feet from the ground.

Hevea BrasiLiensis (Para RuBBeR), — The
trees in this plot that were planted during 1901
fruited during the year, The seeds, were sown
and 100 per cent germinated,
THEOBROMA Cacao var, ForasteRo.— These
trees have fruited well during the year and over
10,000 pods were sent out to planters in different
parts of the Colony for planting purposes.
THEOBROMA PentTacona.—The plants of this
species that were planted out last year are
growing well and over 100 plants were again
successfully grafted on to the stocks of Theo-
broma cacao var. Forastero and are growing
satisfactorily.
THEOBROMA Cacao var. OcuMARE.—This
variety is growing remarkably well and experi-
ments are being carried out to see how this
variety behaves when grafted on the forastero
type. In last year’s report mention was made
that 8 tons 14 cwt. of cacao prepared by nine
farmers shipped to England through the Gov-
ernment with a view of ascertaining what a
better prepared cacao would really fetch.
- Below is a report by Mr Crowther, Secretary
for Native Affairs, which was published in the
Government Gazette, in June, 1907 :—
Representations as to the trade conditions of the cacao
industry having been made to the Government by several
of the more intelligent native planters, His Excellency the
Governor in September, 1906, gave instructions for an
experimental shipment to be made. The chief causes
of complaint were that the local merchant purchased
the raw product at a fixed price irrespective of the quality
or condition of the bean, and that the price paid to the
farmer was such as toallow an unduly high proportion of
profit to pass into the pockets of the local merchant.
2, Correspondence passed between the Government and
the Director of Imperial Institute, and, as a result a con-
signment was made in the manner, and with the results
described below. The cacao grown and prepared by native
farmers was brought to the Botanic Station at Aburi, ard
finally dried under the supervision of the Acting Director
of Agriculture. It was conveyed to the coast by means of
head loads and motor-lorries. The total quantity brought
in was 8 tons 14 cwt. and this was shipped in two consign-
manta to a firm of brokers in Liverpool who placed it on the
market, : $
3. Between the time when the experimental sale was
suggested and the date of its completion, however, trade
had undergone a radical change. There had been a marked
increase in the demand for West African cocoa and also in
the supply; the price paid for the raw product in the
English markets had risen from 40 per cent. to 50 per ce nt
and there was a rise of corresponding proportions, due to
the competition of buyers who refused to join the local
“ eombine” of merchants, in the sum paid to the local
farmer. These circumstances, gratifying as they are, hada
tendency to render less prominent that feature of the ex-
periment that it was most desired should be’ brought into
light; namely, the superior quality that may be obtained
by the employment of greater care in the preparation of
the bean; for it was quantity rather than guatity that the
abnormal demand sought. But, nevertheless, the result
can be regarded only with satisfaction,
4. The cacao which was exported in two shipments was
placed on the market on two. different dates. The first con-
signment sold in one lot on the 22nd January, realised 68/-
per cwt. The second consignment was sold in six lots on
February the 8th, of these, two lots realised 65/-, one 67/-,
one 68/-, one 69-, and one 70/- per cwt. Taking into consi-
deration the actual quantities of these sales the average
price for the second shipment was 67/- per cwt., and for
the whole consignment 67/8 per cwt., a sum which repre-
sents 2/8 above the quoted current price.
5.. When such charges as freight, transport, commission,
&c,, are deducted the amount due to the grower is 56/3
per cwt., which, as the current price paid by the local
merchant at the time of this trial shipment was 50/-, is
equivalent to an increase of 12} per cent. That is to say,
the local merchant has a sum equal to 12} per cent. of the
pea he pays for the raw product—out of which must come
is office expenses, risk and-profit.. — j J
408
6. Accepting the amount realised on the home market
at 67/6 per cwt the proportion of this sum which goes to the
grower atthe local market is equal to 74 per cent ; the cost
of transport from the local market to the port of shipment,
freight, commission, and other charges is equal to 16} per
cent ; and the proportion due to the local merchant is equal
to 9} per cent. The figure of the percentage falling to the
producer appears higher than it is in reality, as the cost of
transport from the farm to the local market is such that
every average day’s journey of 20 miles reduces it by a sum
equal to + percent of the sale value of the raw product on
the English market. :
7. The experiment proves that a well prepared cacao will
realise a higher price than one of an indifferent grade, and
it has disclosed figures representative of the normal propor-
uions of the profit falling to the hands of the various sec-
sions of those engaged in the trade.—(Signed) FRANCIS
CROWTHER, Acting Secretary for Native Affairs.
HOW TO OBTAIN PALE RUBBER.
There being a difference in price of over
30 cents per lb. between pale and darker biscuits
and crepe, ‘‘Onlooker,” in our contemporary,
describes a practical application of the principle
of destroying enzyme with slight modifications:—
‘When coagulating the many vessels containing
the latex were stood in another large vessel con-
taining hot water of about 160° Fahrenhoit, and
kept at that temperature. The coagulation took
place much quicker than that coagulated in the
ordinary way. The rubber when manufactured
was of avery uniform pale colour. Result over
30 cents per lb. greater average price than the
other estate that coagulated cold.
“ Assuming that by this method one’s rubber
sells for only 3d per lb. more, is it not worth
. doing 2? The only extra cost, apparently, is the
value of the water and firewood and a thermo-
meter, and the labour in boiling the water. On
an out-turn of 50,000 lb. rubber it means a
difference in profit of R9,000, which is worth
looking for. On the ‘hot water’ estate all
collecting cups, carrying pails, and coagulating
pans were daily washed in this hot water, and
were always kept perfectly clean; not so on
the others.”
PRECOCITY IN RUBBER TREE.
(fo the Editor, ‘Straits Bulletin.’’)
Dear Mr Ridley,—With reference to your
article in the August number of the Bulletin
on ‘*Precocity of Rubber Trees” it may in-
terest you to learn that on 23rd Dec., 1908, we
successfully raised seedlings from seed obtained
from a Para tree planted as a stump in June,
1906: the fruit set in 28 months, and the re-
sultant seedlings sprouted 30 months from date
of planting out the stump. Over fifty trees
flowered within 28 months of planting out the
stumps and four of these set fruit within 30
months. In all cases stumps were not more
than 12 months old when planted out.—Yours
faithfully,
Frank E. Lease.
Note on above.—Mr Lease’s trees, though very
precocious, are not much more so than the ones
mentioned in the paper referred to, as their age
works out to40 months from seed, i.e., 3 years
and 4 months. The objection to precocity is
not based on any supposed weakness of the off-
spring of the trees, about which, as Sir William
Thiselton-Dyer says, we have no evidence ; but
upon its action on the tree itself, i.e., whether or
no such trees are short-lived. Inthe case of
The Supplement to the Tropical Agriculturist
Nutmegs fruiting in three years, instead of the
normal seven, it is strongly believed, and there
is some evidence for it, that such trees die out
more quickly than the normal ones, There is
no advantage to be gained by the rubber planter
in his trees fruiting early, but there is a great
advantage in their being large and stout trees
early. In the early fruiting trees I have seen
and mentioned the stems were very well deve-
loped and as big as they would have been ordi-
narily at the usual time for fruiting four-and-
a-half to five years. The original Singapore
trees fruited in the fifth year, but the bulk of
the trees descended from them were raised. from
seed when the trees were much older.—Straits
Agricultural Bulletin for April.
COCONUT BEETLES IN THE STRAITS.
In his annual report on the Singapore Bota-
nic Gardens for 1908 Mr H N Ridley writes of
Singapore:—
The red beetle seems to have got quite scarce
among the estates and most of the harm is now
done by the black one. These, however, seem
quite to have disappeared from the vast
accumulations of sawdust at the sawmills in
Rochore, where they formerly bred in myriads
and gave some trouble as it was impossible to
destroy the immense amount of sawdust, in
which they bred. Much of this ground has now
been built over, and the beetles seem to have
entirely disappeared; another kind of beetle was
found in some trees with the black beetle; a
large species of Elater. Only afew were found
and these had apparently entered the burrows
of the Oryctes to feed and are probably harm—
less,—S. F'. Press, April 6.

RUBBER TAPPING METHODS.
Physiologische Grundlagen zur Bewer-
tung der Zapfmethoden bei Kautschuk-
baumen. (Physiological principles by
which to reckon the relative value of
rubber-tapping methods) by Dr. Hans
Fitting. (Beihette zum Tropenpflanzer,
Feb., 1909).
Professor Fitting visited the tropical
gardens of Buitenzorg in 1907 under the
system of subsidies provided by the Ger-
man Goverament. He there devoted
himself toa scientific study of the physio-
logy of rubber bark in its relation to the
various methods of tapping in vogue,
with the result that he has arrived at
conclusions of so much interest to rubber
planters, that we do not think any
apology is needed for giving a brief
account of them, Professor Fitting’s in-
vestigations draw attention to the fact
that the bark of the rubber tree, in
addition to being the seat of the forma.
tion and storage of latex, also provides
the channels through which food sub-
stances manufactured by the leaves find
their way to the roots and base of the
tree. Not only are these food supplies
necessary for the growth of the roots
and consequently for the general wel-
fare and health of thetree, but they also
provide the material from which the
actual rubber is formed in the latex
tubes. It is therefore of the highest
importance to preserve the integrity of
the channels through which the down-
ward food current passes. Any trans-
verse cut through the bark and penetrat-
ing to the cambium will stop the down-
ward current of food-bearing sap for as
much of the circumference of the tree
as the cut occupies, and it is well known
that if a tree is completely and effec-
tively ringed it must ultimately die,
because in this case the food supply of
the roots is cut off altogether. The slop-
ing cut made in all the ordinary methods
of tapping, although it does not 1each
the cambium, also materially checks this
downward current, especially if it is
combined with the use of the pricker;
and the wider the area of bark operated
upon becomes, the greater is the obstruc-
tion caused in the vitalizing current.
It is highly probable that the ill-effects
of over-tapping are quite as much due
to checking of the downward food sup-
ply as they are to the actual removal of
latex. Professor Fitting therefore joins
issue with Mr. Herbert Wright with
regard to the well-known dictum of the
latter—‘‘ The best method of tapping is
that which extracts the maximum
amount of latex from the tree with
removal of the minimum quantity of
cortical tissue, and without damaging
the thin layer of cambial cells.” He
maintains, on the contrary, that the
best results will be obtained in the long
run by those methods which leave the
widest possible area of free bark un-
blocked in a vertical direction, ana
therefore advocates such a system as the
410
herring bone or half-herring bone, in
which only a quarter of the tree’s cir-
ecumference is tapped at a time. Inci-
dentally we may point out that Professor
Fitting’s observations explain the pheno-
menon observed by Mr. Chas. Northway
in the application of his basal V system.
After paring one V at the base of the
tree for some time, a second V_ was
started a foot above the old one, and
it was found that the yield from this
second V was now little less than that
from the first, although if two Vs are
started simultaneously, one a foot above
the other, the initial yield from the
upper V is very much smaller than that
from the lower. This must be due to
the fact that the downward stream of
food-laden sap is checked by the first
basal V, and the concentrated tood
supply is then used by the cells above
in the production of a larger amount of
rubber than would otherwise have been
formed.
New systems of rubber tapping are in
the air, and we strongly recommend
Professor Fitting’s observations to the
serious consideration of the authors of
these new systems.

COTTON CULTIVATION: ITS EX-
TENSION IN CEYLON.
Report by Mr. J. Stewart J, McCall,
Director of Argiculture, Nyasaland. Cir-
culars and Agricultural Journal of the
Royal Botanic Gardens, Ceylon, Vol. IV.,
No. 19, March, 1909.
The world’s demand for cotton in-
creases steadily; the supply does not at
present show signs of responding to
the demand by a proportionate increase.
Egypt and America, the two great
sources of better class cottons, are, it
appears, already producing almost up
to their full capacity for this kind of
crop. Now, if ever, is the time to extend
the cultivation of cotton into new
territories, and to improve the yield
and value of the’ fibre in regions where
it is already grown.
Extensions are already being rapidly
made in Africa. The West African crop
for 1907, we learn, was promising, but
the East African crop, on the other
hand, was injured by disease. Nyassa-
land has now the advantage of having
a cotton expert as its Director of Agri-
culture in the person of the writer of
the report under review. It seems un-
likely, however, that the extension of
cotton cultivation in Tropical Africa
[May, 190 9
will either meet the demand or materi-
ally reduce the price of this commodity
for some time to come.
Under these circumstances Mr. Mce-
Call’s report appears ata very opportune
moment. And the view which he takes
of the prospects of cotton as a staple
crop for the drier regions of Ceylon is,
we are glad to observe, on the whole,
distinctly favourable. The account given
of the poineer work already carried out
at the Experiment Station at Mahailup-
palama isan appreciative one, and the
writer believes that when certain sug-
gested modifications have been made
in the methods adopted, this experi-
mental cultivation will rapidly be
brought toa highly satisfactory condi-
tion of efficiency.
The report isan eminently practical
one; and the writer gives a detailed
account of the exact methods which in
his opinion should be adopted for the
eultivation of cotton under the condi-
tions obtaining in the North-Central
Province of Ceylon. For details re-
ference must be made to the report it-
self, which was reprinted in full in the
last number of this Journal.
One point upon which Mr. McCall
lays stress may here be emphasised.
The introduction of a new annual crop
into any country is invariably followed
by certain changes in habit and quality,
which ought to be carefully watched in
order that beneficial variations may
be encouraged and harmful ones elimin-
ated. Inthe case of cotton, especially,
itis well known that, in order to keep
up the quality of the crop, careful me-
thods of selection must be applied. This
necessary selection of seed-bearers is
a task which can be undertaken to some
extent by the ordinary cultivator under
expert supervision. On the other hand
we are faced with a strictly scientific
problem in the desirability of breeding a
special cotton of the highest possible
quality suited to the conditions of
Ceylon cultivation.
Mr. McCall very properly calls atten-
tion to the Imperial aspects of cotton
cultivation. He considers that more
than a fifth of the population of Great
Britain is more or less directly connect-
ed with cotton in trade. There are
therefore reasons, apart from those of
gain, which make the growing of cotton
desirable ina British Colony; reasons
at least strong enough we trust to make
the intending cultivator favour this
particular cultivation in perference to
one of smaller imperial importance so
long as the latter has not been shown
to be the more paying proposition of
the two.

THE NEW RUBBERS.
[Paper read before the Board of Agri-
culture on April 7, 1909.]
A good deal of information has
appeared during the past year in the
“Tropical Agriculturist ” and elsewhere
concerning certain novel varieties of
Manihot, the genus to which Ceara
Rubber belongs. The reports so far
received as to the growth and yield of
these rubber trees in their native country
are so remarkably promising that little
or no apology seems required for an
attempt to put briefly before you a
summary of what is known at present
about these new and _ interesting
species.
The first piece of information with
regard to these species to be received at
Peradeniya came in the form of a
circular from Messrs. Vilmorin, Andrieux
& Co., the great firm of seedsmen in
Paris, dated February 15, 1907. In this
circular a price was quoted for a large-
seeded species of Manihot—name un-
known—which was stated to be superior
in many respects tothe Manihot glaziovw
or Ceara Rubber. An order for 1,000
seeds of this species was at once des-
atched by Dr. Willis, but owing to the
failure ot Messrs. Vilmorin’s supplies the
order was not executed until last year.
The seeds were received in August, 1908,
and 500 were sown on the Experiment
Station, Peradeniya, on the 12th of the
month. 280 of these seeds germinated
and developed into strong seedlings.
They were planted out 12 by 12 feet
apart in December, and, in spite of bad
weather for planting, they are all doing
remarkably well owing to special precau-
tions taken at the advice of Mr. Kelway
Bamber.
At Kew, according to arecent bulletin,
the first account of the new rubber
plants was received in March, 1906, when
Mr. J. A. Davy, a Brazilian planter,
called at the Royal Gardens and left
seeds of the Jequié Manihot or Mani-
sobar, the plant to which the name
anihot dichotoma has subsequently
been given. A large consignment of the
same seeds was sent to Kew in October,
1906, by Mr. J. P. Rowe of Bahia, and
from these plants were raised for distri-
bution and sent out from Kew in
Wardian eases on May 23, 1907,
Acase containing 100 of these plants
reached Ceylon in excellent condition.
They were at first put out in a nursery
and were finally planted out on October
8, 1907, on level grouud 20 by 20 feet
apart. Some of these plants have made
excellent growth. The twelve largest
averaged 3 inches in girth, 3 feet from
the ground in May, 1908, and 6 to 7 inches
in November, 1908. Some months ago
these trees began to produce seeds, of
which a small number has been dis-
tributed. It is, of course, too early as
yet to begin any experiments in tapping
the trees, bnt the drop of latex obtained
on pricking the stem appears to be
decidedly rich in rubber.
A further large supply of Manicobar
seeds was received from Kew in Octoher,
1908. These included, inaddition to the
Jequié Manicobar, Manihot dichotoma,
already mentioned, a second kind, the
Rémanso Manicobar or Maninot piau-
hyensis, which is said to be superior to
the former in many respects. 2,000
seeds of each species were sown at
Peradeniya on November 2, 1908, whilst
others have been planted at Maha
Iluppalama, Henaratgoda, and _ else-
where. Out of 200 seeds of the Dichotoma
sown at Henaratgoda, practically all
germinated, so that there is every pro-
mise that the Departmeut will soon be
in possession of a good supply of plants.
At Peradeniya the ge:mination was not
so good, and only a very few plants of
the Rémanso variety have appeared.
The three species of Manicobar which
have been botanically described—
Manihot dichotoma, M. piauhyensis, and
a third M. heptaphylla, seed of which
we have not yet succeeded in obtaining
in Ceylon—occur wild in the Provinces
of Bahia and Piauhy in Brazil in latitudes
ranging from 8 to 15 degrees South.
So far much the fullest account of
these plants in their native country is
that given by Dr. Ulein the ‘‘ Tropenp-
flanzer’’ for December, 1907, a transla-
tion of which appeared in the ‘ Tropical
Agriculturist” for Mareh, 1908. From
this account it appears that these species
grow naturally in a much drier and more
mountainous country than the Para
Rubber (Hevea brasiliensis).
“Here Manihot dichotoma grows in
the true Catinga forest, and is especially
abundant on the mountain spurs. The
mote park-like regions where individual
trees stand scattered is avoided by
M,. dichotoma, which prefers a rather
more thickly wooded country. It de-
Gums, Resins,
velops best ona ved loamy soil, and is
less frequently to be found ona sandy
substratum. Within a few miles of
Porto Alegre onthe Rio das Contas, a
central station for the production of
rubber from this species of Manihot, I
have seen the mountain spurs so thickly
covered with this tree that it made up
almost half the total forest.” (Ule.)
For an account of the methods em-
ployed in tapping these trees ina wild
state, and of the yield so obtainable,
reference may be made tothe above-
mentioned translation of Dr. Ule’s
paper, We are now more directly con-
cerned with the value of Manicobar
rubber as a cultivated product when
planted on estates. Dr. Ule gives it as
his opinion that the wild thickets of
Manihot dichotoima will very soon cease
to have any value as a source of rubber.
The export of rubber from the State of
Bahia is said to have increased more
than ten-fold between the years 1900 and
1906, that is to say, from 100 tons to over
1,100 tons, but very little of this was
from plantations. Recently, however,
large areas in this district appear to
have been planted up with these Mani-
cobars, and from the accounts given by
Ule and others the success of these
undertakings seems to be assured.”
It appears from the “ Agricultural
News” of October 17, 1908, that this
export fell off somewhat in 1907. This
result is probably to be ascribed to
general trade depression and not to any
failure in the estate product. It is also
possible that the collection of wild
rubber may fall off more rapidly than
can be made up for by the increase in
estate produce.
The recognized distance for planting
in Brazil would appear to be at the rate
of 1,000 trees per acre, that is to say, 6
or 7 feet apart, and Dr. Ule speaks of
yields of a ton of rubber per acre from
such plantations. The ‘‘ Kew Bulletin”
quotes Mr. Rowe, a resident of the
country, to the following effect :—‘‘ Our
plantations are mostly formed of young
seedlings taken from the forest, which
contain vast numbers. They are trans-
planted 1,000 to the acre, and they do
not appear to be too crowded. ‘The
transplantation causes no apparent set
back, and the close planting has a good
effect in keeping down the scrub and
undergrowth. At three years old culti-
vated trees have yielded 7 ounces of
rubber on the average.” As _ regards
price, Mr. O’Sullivan Beare, H. B. M.
Consul at Bahia, reported in 1907 thata
planter established in the Jequié District
prepared a considerable quantity of
rubber obtained From Manicobar trees
412 [May, 1909.
growing wild in the neighbourhood and
despatched it to New York. The con-
signment was classified in the New York
Market as being equal to the best Para
Rubber, and fetched 5s. a pound.
The following advantages are claimed
by Messrs. Vilmorin for the new rubbers
as compared with ordinary Ceara.
The latex is not so thick ; it coagulates
less rapidly, and is therefore easier to
deal with; it yields a rubber of much
higher quality.
Secondly, it contains a much larger
proportion of pure dry rubber.
Lastly, the yield is greater. Whereas
the raw rubbers of Ceara and Piauhy
give only 60 to 67 per cent. of pure
caoutchouec, the proportion obtained
from Manihot dichotoma varies from
70 to 92 per cent. These figures do not,
of course, refer to plantation rubbers,
Itis possible that some of the state-
ments which we have quoted in the
above notes may b3 of a more or less
Utopian character. Still the opinion of
Dr. Ule and of Messrs. Vilmorin is largely
confirmed by the independent authorities
quoted in the‘‘Kew Bulletin,” and it
seems clear that the new rubbers are
worthy of an extensive trial in the drier
districts of Ceylon. The choice of one or
the other of the three species which
have been described will probably de-
pend for the present upon the supply of
seed. Of Manihot heptaphylla, which
Dr. Ule seems to regard as somewhat
the best of the three, no seed is at present
available. Of the two remaining species,
M. dichotoma is said to be the better for
planting on a heavy clay soil and
M. piauhyensis for light sandy soils. On
the other hand, it must be pointed out
that M. dichotoma is growing well at
Paredeniya on land which cannot
possibly be called a heavy clay.
Manihot dichotoma germinates most
easily of the three, and it appears to be
quite unnecessary to file the seeds of this
species before planting. Dr. Ule also
states that the rubber from this
species fetches a higher price than that
from either of the others. On the other
hand, he states that the yield from the
two remaining species is decidedly
greater. Jn the most recent article
seen (by a Bahian planter in the
“Journal d’Agriculture Tropicale”), M.
dichotoma is regarded as decidedly the
best of the three species. On the whole,
the conclusion seems to be that any one
of the three is very well worth a trial.
Except possibly on land like that under
the tanks of the North-Central Province,
which is readily capable of machine

cultivation, close planting at 8 by 8 feet,
or even less, is to be recommended.
reservation may also be made in the case
of the first few acres of land planted,
where it may be worth while to give the
trees plenty of room in order to encour-
age the production of seed at an early
age. But if our own experience of trees
flowering at one year old is repeated,
there should be nolack of seed ina
few years’ time. Having trees at
Peradeniya with more than a year’s
start of the rest of Ceylon, itis perhaps
legitimate for us to entertain the hope
that suitable methods of tapping the
trees and of preparing the rubber may
be worked out there by the time the
crop begins to be at all widely estab-
lished.
REPORT OF THE DIRECTOR
OF AGRICULTURE FOR
THK F,M.S. FOR 1907.
THE YIELDS oF Dry RUBBER PER TREE.
The average amount of dry rubber
over the whole Peninsula is 1 lb.12 oz.
per tapped tree, exactly the same
figure as was recorded for last year.
This is most encouraging, as the number
of trees which are being tapped for
the first time far exceeds those already
tapped, especially in Selangore, where
the average isl lb. 7. oz. per tapped
tree.
Experiments are being carried on in
various parts of the Peninsula: Perak,
Selangore and Negri Sembilan, in
regard to yields of comparatively old
trees which have not previously been
tapped. Jn Krian thase experiments
have been carried out for nearly four
months, only half the tappabie area
of the trees being used and space being
left so that more than three years will
elapse, with continuous tapping every
other day, before the healed surface
will be again reached. The figures
for one year will be published in next
year’s report, but as far as they have
gone the yields average more than 2 lbs.
per mensem per tree. The trees are
planted widely apart round the edges
at graveyard and are about 17 years
old.
There is as yet not sufficient evi-
dence as to what yields may fairly be
expected over large areas of trees from
10 to 20 years old, but all the data which
we have at present points to the fact
that estimates or prophecies of pro-
bable yields at these ages will be amply
confirmed,

MARKET PRICES AND THEIR EFFECTS.
Various circumstances during 1907
led to adecreasein the extraordinary
rapidity with which land was acquired,
cleared and planted in rubber. In some
cases, lack of the necessary superinten-
dence and labour for opening land stop-
ped work, in others a gradual increase
of the cost of bringing an estate into
bearing, and the fact that this increase
had led to the cost of opening and plant-
ing in some estates being greater than
had been estimated hindered plans for
future clearings.
The steady drop in the price of rubber.
especially during the last half of the
year, had the effect of making capitalist
abate the feverish anxiety to get as
many acres planted up as quickly as
possible and to some extent regardless
of cost.
These circumstances did not reduce
the investor’s confidence in the profit-
earning possibilities of plantation rubber
as the share prices of Malayan Compa-
nies showed, but the visions of Eldorado
assumed more natural tints and led to
a careful consideration of the most eco-
* Those figures are approximate,
Gums, Resins,
nomic and improved methods in the
cultivation of rubber.
The industry is still yielding excep-
tionally handsome profits, and such
questions should be considered and ex-
perimented without delay. Recent
history has shown us that in the case
of other tropical agricultural indus-
tries the desire to practise the most
approved methods of — cultivation,
and the cheapest way in which to
carry them out, came only with a drop in
profits. Cultivated rubber in Malaya
pays a handsome profit on money in-
vested, but that seems to be no reason
for not being constantly on the look-
out to find in various directions methods
of saving in cost of production and
improved cultivation.
To carry ona rubber estate or any
other agricultural enterprise for a num-
ber of years, paying large profits, but
without any alteration in the manage-
ment of the estate, the details of culti-
vation or the preparation of the _pro-
duct for the market, must be considered
as curious and discreditable, since it
shows that experience and knowledge
has in no way helped to improve
methods or economic working.
The rubber market was in common
with all other trade affected to a large
extent by the financial trouble in Ame-
rica. Itis the custom of manufacturers
to keep in stock sufficient unvulcanised
pure rubber for six months’ operations,
it is therefore possible for them_ to
continue to work for some time with-
out purchasing new stocks. The stock
in England and in Germany was conse-
quently increased and the price very
greatly affected. At the beginning of
the year plantation rubber was sold at
5s. 9d., which quickly dropped to 5s.,
recovering in July, but after that time
dropping, quickly and steadly, till in
November, the lowest price then record-
ed for best plantation rubber before,
viz., 3s.4d,, was reached, being a drop
of 100 per cent. from the price of 15
months previously. That this drop in
prices was to a very large extent due
to a financial and not to ordinary
‘supply and demand” causes is admit-
ted by those who have largest ex-
perience of the fluctuations of market
prices. The price will recover and pro-
bably vacillate about 4s. It is satis-
factory to remember that even the
lowest price yet reached for plantation
rubber is more than 100 per cent. above
the cost of production.
OVER-PRODUCTION AND SYNTHETIC
RUBBER.
The fear of over-production which
bulked very large a year or more ago
has, owing to moreaccurate knowledge
414
[May, 1909.
of the world’s demand for rubber and
the amount produced, to some extent
subsided.
The drop in prices, while having the
effect of reducing the amount of rubber
planted, may also to a great extent
reduce the output from Brazil, where
the margin of profit is much less than
in cultivated rubber.
This also should lead not only to a
consideration of cheapening of methods
of production, but to the possibilities
of increasing the demand for rubber.
No product lends itself more to mea-
sures for improving and widening the
market. The almost endless possibilities
to the economic uses of rubber, and the
small proportion of the purchasing
population of the world which at present
knows and uses rubber, both demon-
strate the fact that measures taken to
provide new outlets for rubber are much
more hopeful than in the case of food
or textile products like coffee or copra,
which have a comparatively limited
number of uses.
It is not to the interests of cultivated
rubber that the output of the Brazilian
product should decrease very rapidly.
There is not yet sufficient cultivated
rubber or wild rubber from other sources
to supply the increasing demand.
Those who look forward to a future
with immense areas of cultivated rubber
in suitable climates, of which the
Malaya Peninsula can claim to be the
best, believe that cultivated rubber will
in time satisfy all manufacturers in
regard to its physical qualities and
will be produced in sufficient quantity
to meet the world’s requirements.
It is not easy to foresee the future
demands for rubber, but a substance
which has made itself so indispensable
to all civilised races must be required in
increasing quantities, and the fear of
over-production may he cancelled, by
the quite as likely possibility of the
supply not meeting the demand and the
consequent resort to other substances
as substitutes for rubber.
The question of what are termed
‘‘rubber substitutes” has been much
discussed, and various scares of im-
portant discoveries have made the flesh
of those interested in rubber creep.
That various substances can be used
instead for rubber for various purposes
is acknowledged, just as cotton can be
used for silk, or paper for cotton, but
that is a different question to the pro-
duction of a substitute for rubber which
will possess the physical properties of
rubber to which all its commercial
value is due. In this direction the year
May, 1909.] 41
1907 had nothing to show, and December,
1907, was no nearer than December, 1906,
to the practical solution of the problem
which would produce a great rival to
plantation rubber. Chemists and those
best able to judge of the possibilities of
the discovery of a substance having all
the physical properties of India rubber
made from crude materials of so cheap
a nature as to be able to undersell the
natural article, cannot foresee success,
and all so-called pertect substitutes for
rubber brought before the public have
failed to survive investigation.
IMPROVEMENT IN PLANTING METHODS.
One satisfactory effect of the drop in
prices has been a serious tendency to
consider whether the present methods
of opening and keeping up an estate
could not be modified so as to save
expense.
In every industry profits very large
in relation to the cost of production
have a tendency to produce a perhaps
too liberal treatment of expenditure,
and in rubber this is the case, compared
with the practice in the tea and coffee
industries in Ceylon and Southern India.
Rapid planting of healthy vigorous
trees was the object aimed at, even if
this was achieved at a larger cost per
acre than slow and less expensive
methods might have incurred.
HEALTH oF RUBBER TREES.
The health of rubber trees has re-
mained good during the year. No new
disease has to be chronicled, and the
diseases which were already known
have shown no special activity. Both
the root fungus (fames semitostus) and
the rubber termite (Termite gestroi) have
done a large amount of damage.
The Government Entomologist carried
on 2 most successful investigation into
the life-history of the rubber termite,
discovering many details of its methods
of attack, a knowledge of which’ will
enable the planter to carry on a much
more successful campaign in the future.
It is much to be hoped, considering the
immense monetary loss caused by this
ubiquitous pest, that these investiga-
tions will soon be continued and com-
leted. The interim report which he
les published shows among other in-
teresting facts that the planters’
methods of only dealing with the white
ants when he finds them on a rubber
tree are not the most strategical mea-
sures of attack. The rubber termite is
found in large quantities in decaying
stumps, and it is in these places that
they can be destroyed in large numbers,
whereas there are ants differing very
slightly in appearance which are found
5 Saps and Hauudations.
on rubber trees which do no damage to
the living rubber tree.
The nests and their characteristic con-
necting tunnels are clearly described by
Mr. Pratt, and the planter is thus
enabled with more definite knowledge
to carry on the war against this most
insidious and ever-present menace to
healthy rubber.
In addition to this valuable piece of
work, the Government Entomologist
investigated and reported on an attack
by a longicorn beetle on rubber, a sting-
ing caterpillar (T'hosea sp.) on coconuts,
and made anexamination of some paddy
insects which he was unable to follow
up so as_ to gain definite knowledge
as to the life histories and methods of
attack of these pests.
The Government Mycologist has visited
various estates and given advice as to
the prevention and cure of various
diseases of cultivated plants.
RUBBER MACHINERY.
The number of estates which have
srees of sufficient growth for tapping is
as yet not very many, but each year
more become productive, and the
question of the best and most economical
machinery for preparing rubber for the
market and for cleaning ‘‘ scrap,”
“bark” and ‘‘ earth” rubber is one of
the most important in the profitable
working of an estate.
Dr. Kuhleman, Chemieal Adviser to
one of the largest rubber manufactories
in Germany, paid a visit recently to this
country to acquaint himself with the
methods of the planter in his prepar-
ation of rubber. He was impressed by
the care which isuniversally taken to
ensure the purity and cleanliness of the
rubber sent home.
In asking his advice upon the plant
used by the planter, Dr. Kuhleman
informed me that one point which he
noted was that the washers and rollers
in use on estates were so short in length.
This was thecase in the beginning of
the manufactories ~ in Germany.
Machinee with narrow rollers were at
first putup, and then when these could
not deal with the amount of rubber
required more were added, but it was
soon found more economical to have
one roller of 10 feet length than five of
2 feet. It will be well that planters
should, in making arrangements for
their rollers and washers, look ahead to
the time when they are producing much
larger quantities of rubber than at
present. The machines at present in
use are, for dealing with a large
quantity of rubber, mere toys, and will
either have to be multiplied or larger
machines put in.
Gums, Resins,
The longer roller has an advantage
over the short ones at present in use
that the risk of oil from the bearing
reaching the rubber as it passes through
the rollers is decreased. Rubber prepar-
ed in a number of small-length machines
will be in more danger of being dis-
coloured at places than that prepared
in fewer and longer rollers.
The length of rollers in rubber-wash-
ing machines used in factories in Kurope
is often 12 feet, whereas, as a rule, on
estates in the Federated Malaya
States two or more rollers of not more
than a foot in length are often used.
PREPARATION OF RUBBER FOR THE
MARKET.
Block rubber, the advantages of which
for packing, transport and preparation
are undoubted, has not commended itself
generally to the planter. Until large
quantities of any of the forms of rub-
ber produced in Malaya, viz., block,
crepe, and sheet, are put on the market,
it will not be possible to settle the
much-vexed question as to the advan-
tages of each. A sale at a high price of
a shipment of any of these forms at once
produces the impression that that
special form is more attractive to
buyers and will command better prices,
but it should be remembered that the
quality of the rubber as well as the
shapein which it is sent is a factor,
and the most important factor, in deter-
mining its market value. In whatever
form it is sentitis of the most vital im-
portancethat planters should continue to
aim atthe purest and cleanest rubber.
The manufacturers have begun to realise
the advantages of the freedom from
impurities which Kastern plantation rub-
ber possesses, and this good opinion
is too valuable to be endangered by
using less care in preparation.
RUBBER SEED FOR OIL MANUFACTURING
PURPOSES.
Rubber seed, both with the husk on
and decorticated, has been sent to the
Imperial Institute and to various com-
mercial firms dealing in such products
in Europe and Australia in order to
introduce this article to them with a
view to a future market.
The oil from the seed is a drying oil
not unlike linseed oil in appearance and
smell, and probably will prove as good,
as, if not better than, the latter oilin
manufacture of paints and varnishes,
Manufacturers or dealers wishing to
have samples of the seeds either de-
corticated or in the shell should com-
municate with this department. A profit
per acre—after paying all expenses of
picking, husking, packing and shipping—
of at least $5 to $8 may be earned on
estates with trees in full fruit bearing.
416
[MAY, 1909.
While the demand tor considerable
quantities of seed for planting purposes
continues, this method of disposing of
seed is very much more profitable than
the sale for oil, but with an immense
number of trees producing fruit the
supply for planting purposes will soon
greatly exceed the demand and an
additional market is needed. If the
seed are left on the ground they
germinate freely, and money must be
spent in weeding out the young plants.
The question in regard to the best
methods of preparation and packing of
the seed in exporting it for oil purposes
continues to engage the attention of the
Department of Agriculture, and a
further report will be issued.

EXPERIMENTS IN TAPPING CEARA
RUBBER TREES.
Address by Dr. Wilcox at the Ha-
waiian Rubber Growers’ Association,
Second Annual Meeting.
The rubber experiments which are
being carried on by the U. S. Experi-
ment Station and Territorial Board of
Agriculture and Forestry have been
under way long enough to indicate cer-
tain results which are of practical im-
portance to rubber growers. Thus far
more than 200 trees, most of them less
than three years old, have been tapped.
These trees averaged from twelve to
thirteen inches in circumference and
were located chiefly on the grounds of
the Koclau Rubber Company, on Maui.
In tapping young trees it was not ex-
pected that profitable returns of rubber
would be obtained; but the plan in-
volved the practical point of determin-
ing the rapidity with which trees could
be tapped, and satisfactory methods of
handling labour to the best advantage.
In the first series of eighty trees, which
were tapped by means of one verticle
cut each day, it required thirty-six
hours and forty minutes of labour to
tap the trees, collect the latex, and
secure 1$ pounds of dry rubber. In
the second series of experiments on 160
trees, which were tapped with two
verticle cuts instead of one, it required
only forty hours of labour to tap the
trees, collect the latex and obtain five
pounds of first-class rubber and about
a pound of scrap rubber. In this ex-
periment in which two verticle cuts
were used daily, profitable returns
were obtained.
1t was found that an ordinary labourer
could tap rubber trees, by means of
two long verticle cuts, at the rate of
about fifty trees an hour and could collect
latex at the rate of one hundred trees
[May, 1909. 41
an hour. Theavailable labour on plant-
ations appear to be reasonably effective
in doing this work, and the amount of
training required in order to make the
cuts effectively and quickly is not
excessive.
It requires less time to tap older trees
than the young trees, upon which our
work is done, and there is also less
danger of injuring the trees. Wehave
found that a good flow of latex can
be obtained from tapping done from
daylight until 8a.m. or even later.
From the experiments which we have
thus tar conducted it appears that one
man can tap about fifty trees per hour,
while another man can _ collect the
latex from the trees which would be
tapped in the same time by two men.
Since it appears from results which
we have obtained from tapping mature
Ceara rubber trees, that about one-
third ounce of dry rubber may be
expected as a daily yield, it is evident
Saps and Heudations.
that three men should be able to ob-
tain rubber from mature trees at the
rate of about one pound per hour. The
data upon which this conclusion is
based have been carefully considered
and the estimate is probably not above
what may be expected. At any rate,
the results obtained in our experiments
indicate clearly that the Ceara rubber
tree in Hawaii will not only grow and
thrive, but will yield profitable returns.
Farther experiments will be carried
on in the microscopic examination of
sections of the Ceara rubber tree to
get a basis for determining the best
method of tapping. Several other
species of rubber trees will also betapped,
and an elaborate series of fertilizer
experiments with rubber is planned,
We hope to be able to devise a method
of fertilizing rubber trees so as to secure
an increased flow of latex during the
tapping periods.—Hawaitian Forester
and Agriculturist, Vol, V., No. 12,

OILS AND FATS.
A PLEA FOR SUNFLOWER
CULTIVATION,
By W. F. SuTHERST, PH.D., F.I.C.,
Marist Bros.’ College, Uitenhage.
The cultivation of sunflowers does not
pay in countries where land is dear and
consequently growth restricted, but
here in South Africa, where millions of
acres of land are still lying idle, there is
no doubt that it would pay. The intro-
duction of a new crop would also mean
fresh employment for the surplus
country population, as without moder-
ate export of agricultural produce, over-
production of maize, oats, etc,, is soon
reached... Not only the cultivation itself
needs Jabour, but the atter-treatment
for the production of oil would also
utilise some of our unemployed. Most
of our agricultural produce when grown
requires no further treatment, Very
little care is necessary in sowing the
seeds, mere scattering them over the
pewly-ploughed ground being all that is
required, the depth, as fixed by the
plough, never being too great in this

four months the crop is ready for
harvesting, For opening up new ground
with the least trouble and quickest
returns its cultivation is ideal for the
Colony, as with the cash obtained one
can open up more ground.
The seeds contain about 50 per cent.
of oil, 2.e., without husk, and it would
save enormously if the seeds were first
decorticated, as the husks contain
practically no oil, and, making up about
40 per cent. of the whole, a great saving
in carriage is effected, as well asin the
further treatment of oil extraction.
The residual oil-eake is most nutritious
for all kinds of stock, especially dairy
cows and fattening stock. Little is
heard of it at present, as it is manufac-
tured in such small quantities, but once
started there is no limit to its uses. So
tar very small quantities of oil-cake are
used in South Africa, as it hasall to be
imported, and the cost is prohibitive,
except for owners of high-class stock.

If the seeds cannot be pressed on the

the beet sugar factories, where the

not nearly so nutritious. By far the
best plan would be for farmers to co-
operate and set up an oil crushing mill

We see here a low percentage of phos-
phoric acid and lime, in which our soils
are also deficient, and the growth of a
crop succeeds best and most economi-
cally when itcan be arranged that it
takes out of the soil ite mineral matter
in proportion as itis present, a better
crop could not be found for the country.
This is, however, a_ state of scientific
farming that is not likely to be reached
for some time to come.
Theaverage yield of seeds is about
4 tons per morgen, which means about
2} tons of decorticated seed, and with,
say, about 40 percent. of oil extracted,
gives nearly one ton or over 200 gallons
of oil per morgen.
We see here room for a fairly large
profit if an economically-worked factory
is setup, or even if exported the seeds
should pay their way.
We often hear that the sunflower robs
the soil and leaves it in a poor condition,
but if all the crop is returned to the soil
again, except the oil, which contains no
mineral matter, as would be the case
under the above conditions, no loss

THE AFRICAN OIL PALM AND
ITS PRODUCTS.
The well-known Oil Palm of West
Africa (Hleis guineensis) has a wide
geographical range, for it flourishes from
the Gulf of Guinea to the South of
Fernando Po, as well as in the islands of
Zanzibar and Pemba, and along the
shores of the Central African lakes. Of
all the vegetable products of the countries
on the West Coast, the Hl@is guwineensis
is undoubtedly the most important to
the native. The fruit supplies him with
a favourite article of food and forms the
chief article of commerce; with the leaf-
418
[May, 1909.
stalk he builds his house and barn, and
thatches them with leaves, and from
the stem he extracts a pleasant and
(sometimes) intoxicating drink,
During 1907, the total value of the
palm oil and kernels exported from
Southern Nigeria alone was £2,972,252.
{n the same year the oil and kernels
shipped from the Gold Coast were
valued at nearly £221,290, this being an
increase of over £15,000 on the exports of
the preceding year. Supplies of palm
oil have also lately been exported from
the Philippine Islands.
In all the abovementioned countries
from which the produce is shipped, the
oil palm is indigenous and _ occurs
naturally over enormons areas. Little
expense is incurred in looking after the
trees, and the oil must be regarded as
more or lessa natural forest product.
No authentic information has been
placed on record in regard to any syste-
matic planting and cultivation of the
oil palm which may have been made in
Southern Nigeria or elsewhere, or to the
average returns that may be expected
from such plantings.
lt seems reasonable to expect, how-
ever, that if plantations of the palm
were established in many _ tropical
colonies, the production of the oil would
prove a valuable industry. It would be
amatter for experiment to determine
whether the cultivation would be as
remunerative inany given district as
rubber or cacao planting. Some thirty
or forty years ago an estate owner in
British North Borneo, who had consider-
able faith in the profitable possibilities
of oil palm cultivation, planted a fairly
large area. The trees grew well, but by
the time they were nearing the pro-
ductive age, the ownership of the estate
changed hands, and the new proprietor
cut down the young palms in order to
make room for some other product,
The Aftican Oil Palm has been accli-
matised in Jamaica and some of the
other West Indian Islands, where groups
of the trees are frequently to be met
with. Little or no use, however, is
apparently made of the nuts, and, so far
asis known, no attempt has ever been
made to cultivate the palm in regular
plantations.
The oil palm reaches a height of 30
or more feet. Inthe course of a report
on the oil industry of the Gold Coast
which appeared in the Kew Bulletin for
1889 (p. 190) it is stated that the tree
grows best ina moist soil, flourishing in
warm damp valleys. It begins to bear
in its fourth or fifth year, the produce
increasing until its fifteenth, and con-
tinues to bear for atleast sixty years,

Oils and Fats:
A tree produces, on the average, fromt) be obta ined from Mount Banajao of
four to seven bunches of fruit every
year.
The fruits havea fleshy fibrous outer
layer from which the palm _ oil of
commerce is prepared, This layer covers
a hard-shelled nut from the kernel of
which a white oil known as ‘palm nut
oil’ is produced.
A very full and illustrated account of
the methods in use at Lagos for extract-
ing palm oil appeared in the Kew
Bulletin, 1892, (p. 200), From this it
appears that the fruits are boiled in
earthenware pots until they form an
oiky mass. This is transferred to a
wooden trough where it is lett over
night to cool. In the morning the mass
is covered with cold water, and the
natives pound the oil out of the nuts with
their bare feet. The oil gradually rises
to the surface, from which it is skimmed,
and passed through a sieve to remove
the coarser impurities. It is then poured
into a pot and clarified by further
boiling. This palm oil is chiefly used in
the manufacture of soap and candles.
The kernels of the nuts from which
the white oil is prepared, are frequently
exported whole to Europe, after the
shell has been removed by the natives.
The ‘kernel oil’ is expressed by hydrau-
lic presses, and has a number of uses,
one of which is inthe manufacture of
margarine or artificial butter. The
resulting cake is used as a cattle food,
According to the Kew Bulletin a single
tree may yield from 1to8 gallons of oil
per annum, depending on the character
of the soil and the rainfall. The price of
palm oi] on the London market is from
£14 to £15 per ton.
If fuller and reliable data could be
obtained from Southern Nigeria on such
points as suitable distance in planting,
the time and money required to bring a
plantation of oil palms into full bearing,
the average yield of nuts per tree, and
of oil per acre, together with the net
profit that might be expected per acre
Over a given period, these details would
be of the utmost value to enterprising
planters in other tropical colonies who
may be thinking of taking up the cultiva-
tion.— Agricultural News, Vol. VIL., No.

COCONUTS IN LAGUNA AND
TAYABAS PROVINCES.
By A. F. Byars,
Agricultural Inspector, Bureau of
Agriculture.
In the rich Provinces of Laguna and
Tayabas the coconut industry can be
seen In every stage and from every
aspect. The beautiful panoramic view
the vast coconut regions as a whole,
extending from the mountain to the
lake in one direction and to the sea
in another, is most inipressive.
San Pablo, the largest and richest in
agricultural products of all the towns
in Laguna Province and the centre of
the coconut industry, is a town of
about 25,000 inhabitants. It lies along
the main road leading from Los Bajfios
and Bay on the lake to Tiaong and
Lucena in Tayabas, also on the main
road from Santa Cruz to Magdalena,
Lilio, and Nagearlan, and onthe other
side through Alminos on into Batangas,
As arule these roads are very good and
facilitate trade. The ownership of the
coconut groves, from which the town
derives most of its wealth, is distri-
buted among a comparatively large
number of its inhabitants, so that while
none of the people are very rich, none
are very poor.
In this town a large part of the coco-
nut crop is made into copra, which is
sacked and sold in that form. Any day
hundreds of pack horses loaded with
copra may be seen coming from all
directions into the town, where it is
usually sold to dealers, who in turn
load it on carabao carts (eight to ten
sacks to a cart) and send it to Bay,
where it is transferred to boats for
Manila.
Coconuts are not harvested at stated
seasons, but are gathered from each
tree every two to four months, The
nuts are detached by means of a hooked
knife attached to a very long slender
bamboo pole, or by aman who climbs
the tree and cuts the fruit stalks with
a sharp knife. The nuts are collected
in piles and are sometimes husked before
being removed from the groves. They
are carried to the small factories by
means of carts or sleds, or by pack
horses in the hill country. Often they
are floated down rivers and small
streams in the form of rafts, but this is
rather a dangerous means of transport-
ation, as was shown by a late baguio
in Laguna which broke up numbers of
rafts in Pagsanjan River, it being
estimated by some that from 100,000 to
200,000 nuts were scattered over Laguna
de Bay.
MANUFACTURE OF COPRA.
The process of making copra in this
section is very simple. It consists in
husking and halving the nuts and drying,
after which the meat is removed from
the shells. They are husked by means
of a pointed iron instrument, usually a
plowpoint fixed on a three-legged stand.
After it is hulled, a quick blow with
a dull bolo halves the nut. For drying

the copra, a small shelter is built over
a rectangular hole from 1 to 2 meters
wide, 1 meter deep, and as long as
the shed, across which small poles are
laid parallel, leaving a small space
between each two. On these poles are
piled the halved nuts, which are dried
in about two days by the heat and
smoke from the fire in the hole. Empty
shells are used as fuel.
The dried meat, or copra, is then easily
removed from the shells by means of a
thin, chisel-shaped, curved knife pro-
jecting in front of a seat. After a little
further drying the copra is ready for
sacking and putting on the market.
These small copra factories can be found
scattered all aboutin the coconut groves
of Laguna and Tayabas.
MANUFACTURE OF OIL.
During the past two months most of
the coconut crop of Laguna has been
marketed in the form of oil, especially
in the hill country. Of course the small
native factories are crude and a large per
cent. of the oil is left in the cake, but
at the prices now being paid oil brings
better returns than copra.
Where the oil is extracted in the
grove there is no necessity for drying
the meat; it is simply grated from the
halves by a native machine with small
rotary knives. This grated meat is
put in open shallow iron pots and cooked.
The resulting white mash is dipped in-
to sacks and placedin a vertical press
made of two large thick boards anda
large wooden screw. The mash is often
cooked twice and pressed several times,
being milled or crushed beneath a
weighted swinging roller before pressing.
The white, milky mixture of oil, water,
ete., which drips from the sacks is re-
turned to the cooking pan and boiled
until all the oil separates and rises to
the top, when it is dipped off into five-
gallon petroleum tins, and is’ then
ready for market,
MANUFACTURE OF ALCOHOLIC
BEVERAGES.
While copra and oil are the chief pro-
ducts of the coconut industry, a consider-
able number of the groves of Laguna
and Tayabas are devoted to the making
of tuba and alcoholic beverages. Dis-
tilleries can be found in the valleys or
on the hillsides where water may be
had to run through the commencing
tanks by gravity. The Government has
an internal-revenue employee stationed
at each of these ‘‘alumbikis” as they
are called, to collect revenue and see
that they are run according to law.
Tuba is collected from the trees
through the flower stalk. The many
small branches are bound together, their
420%
tips cut off with asharp knife, and the
end of the bunch inserted in a section
of bamboo tube, which catches the
juice. Early each morning a_ tuba
gatherer climbs the tree, empties the
tubes into a larger vessel, and cuts a
little more off the ends of the flower
stalks. Two strong bamboo poles bridge
the distance between the tops of the
trees, and the tuba gatherer passes from
one tree to another, walking on one pole
and holding to the other. When the
receptacle becomes full of tuba he lowers
it to the ground witha rope, and after
it is emptied he pulls it up again. After
the tuba is collected it is carried in
three-or four-gallon vessels to the dis-
tillery on pack horses or by carriers.
Bup-Rot.
The purpose of the writer’s visit to
Laguna and l'ayabas was the inspection
ot these provinces with a view to eradi-
cating the bacterial disease known as
‘‘bud-rot of the ecoconut.’* The name
bud-rot comes from its habit of attack-
ing those portions of the tree which
are in the tender or bud stage. The
flowers are most liable to attack during
the bursting of the flower sheath. Other
tender portions of the apex are subject
to attack at any period, but more parti-
cularly during the rainy season. The
presence of the disease is indicated by
the young leaves turning yellow and
also by the dropping of the fruit. The
decaying bud gives off a very offensive
odour, by which the disease may be
readily recognized.
METHODS OF TREATMENT.
After the disease has made sufficient
progress to destroy or partially destroy
the ‘‘cabbage” there is no hope of saving
the tree. If the disease can be detected
in any early stage of development, it
can be checked by the use of fungicides,
such as sulphate of copper, but the only
practical means of combating it in
these Islands is to cut the tree down
and destroy it by fire as soon as the
presence of the disease is detected.
Owing to the fact that the disease
spreads readily by the aid of the wind,
insects, etc., it is well to destroy all
portions of the tree by burning, if
possible.
PREVALENCE OF THE DISEASE AND
OUTLUOK
The disease is found to be most
prevalent around the base of Mount
Banajao in the municipalities of Neg-
carlan, Lilio, and San Pablo. More than
2,000 trees have been destroyed in one
of the barrios of Nagecarlan. It is
claimed by some of the inhabitants that
the disease bas existed in this town fox
May,’ 1909. }
the last ten years. It is probable that
the moist atmosphere, due to the proxi-
mity of the mountain, has contributed
largely to its presence in this vicinity.
A few cases have also been found in
the towns of Pagsanjan, Santa Cruz,
and Pilar. The damage done in these
towns, however, has been small.
While all the trees showing symptoms
of disease at the time of inspection were
destroyed, itis quite probable that others
have been infected by means of wind or
insects carrying the bacteria and will
develop the disease later. Presidents
of muncipalities, lieutenants of barrios
(some in the most remote and out-of-the-
way places), and the owners of the
groves have been instructed as to the
nature and manner of exterminating
this disease, and all should co-operate
to keep it out, If reasonable measures
are taken to suppress it, the disease
will not prove serious.
Insect ENEMIES.
The insect enmey which has up to the
present time caused more loss to coco-
nut owners in Laguna and Tayabas
than all the other destructive agents
combined is the ‘“‘uang,” or rhinoceros
beetle (Orycytes rhinocerus). This insect
attacks the most vital part of the tree,
the bud, boring through and feeding on
the young tender “cabbage.” The coco-
nut being endogenous, the destruction
of this part means death to the tree.
Thousands of trees are killed by this
insect, but as yet no really practicable
method has been discovered for destroy-
ing it.
Various methods are used with greater
or less success. The beetles may be
extracted from their holes by means
of a hooked wire. Pouring 5 to 10 cubic
centimetres of carbon bisulphide into
the holes and filling the opening with
mud will kill them. Sharp-cornered
sand sprinkled between the base of the
Jeaves and the bud will makeit very
disagreeable for them to enter at this
point. No thoroughly practical remedy
has been found for the beetles when
oncein the tree, but their ravages can
be largely reduced by cleaning the
groves of all dead trees, undergrowth,
and rubbish.
SoME FIGURES ON THE COCONUT
INDUSTRY,
No doubt any information as to the cost
of production will be of great value to
the prospective investor in coconuts.

to make one picul of first-class copra.
A labourer can cut down from 1,000 to
2,000 nuts a day, according to the
height of the tree and the amount of
underbrush in the grove. He can husk
2,000 or raspthe meat from about 1,000

Cost of transportation of cargo (four
tins, or 20 gallons) of oil on apack

Cost of transportation of one cargo
(2 sacks, 3,000 pounds) of copra_a dis-
mone of 10 miles (San Pablo to Bay) is
1.50.
Owners of coconut groves make
several kinds of contracts with their
overseers for taking care of their groves
and gathering and marketing the crop.
A common one requires the overseer
to do all the work of gathering, manu-
facturing, and marketing, standing all
expenditures, and gives him half of the
gross proceeds. Another calls for the
owner to pay for the pulling down of
the nuts and the transportation of the
finished produzts to market, the over-
seer to do the rest and receive one-
third of the gross proceeds.
In manufacturing oil, when the factory
is not the property of the owner of the
grove, the overseer usually pays for
the use of it 25 centavos and one-half the
oil cake per cargo of oil made.
The relative net pzrofitto be derived
from the production of oil and copra
varies with the market prices of these
two products. Sometimes oil, and at
othe: times copra, is the more _ profit-
able of the two. Most natives prefer
making oil so as to have the cake to
feed their hogs.

or otherwise, the question arises, ‘‘ Does

FIBRES.
NEW FIBRES FOR PAPER.
By WILLIAM [tairr,
The scarcity of paper-making material,
which keen observers have seen approach-
ing for many years, is now an accepted
fact. The positicn can perhaps be best
indicated by quoting the remarks of
Lord Northcliffe, the Chairman of the
great Harmsworth group of publishing
enterprises, ata recent meeting of his
shareholders.
‘“‘Itis no secret that the whole world
that lives by paper and print is clouded
by the imminent approach of a rise in
the price of paper. Ihave just seena
list of newspapers in the United States
that have been obliged to double their
price, and another list of those that
instead of doubling their price, have
reduced their size. This rise in price of
our raw material, we know to be chiefly
owing to the depletion of the world’s
supply of the spruce tree from which
this class of paper is made. This
augmentation in the price of paper is
caused by the scarcity of a material that
takes at least thirty years to grow, and
isa much more serious form of famine
than that where an article is concerned
which can be grown in a year or two.”
The ‘world that lives by paper and
print’ is therefore once again face to
face with a recurrence of what has ever
been its chief difficulty,—the sufficiency
and permanence of an adequate supply
of raw material. The last crisis of the
kind was about 1875 when the rapidly-
growing requirements outran the supply
of Esparto, which for twenty years
previously had been the staple material
for print and newspaper. Woodpulp
arrived just in time to save the situa-
tion. It introduced asupply so plentiful
and so cheap that it seemed as if at last
an inexhaustible source had been tapped,
and but few foresaw the inevitable
result of cheapness plus the rapidly
growing demand of education and
culture, upon an article which, as Lord
Northcliffe remarks, takes at least
thirty years to produce. Woodpulp
brought the cost of ordinary newspaper
down from 5 pence per. pound in 1870 to
a penny farthing in 1900. At the same
time an enormous increase in the reading
public was taking place. The combined
result is that whereas in 1870 the World’s
Annual product of paper was about two
million tons, it is now eight millions,
and is growing at the rate of 25% every
ten years. Of this eight millions, six
and a half is produced from wood. Such
an enormous advance on the modest
requirements of forty years ago has
had simply disastrous effects on the
forests of Northern Hurope and America,
Whole countries. whole states, have
gone galloping down the insatiable maw
of the cheap press, until we have now
arrived at this state of affairs:—In the
U.S. A. exhaustion so complete that
the mills there are now importing
supplies of wood from Canada, at a cost
of 50% to 70% in advance of values pre-
vailing when they had forests of their
own to draw from. In Canada there is
still plenty of wood in the back blocks,
which Canada means to keep, having
taken warning in time from the fate of
her neighbour, and she has embarked on
a restrictive policy which aims at reserv-
ing her forests for future timber supply
rather than for present paper supply.
In Northern Europe, deforestation so
huge, that forests are now at great
distances trom mills and ports, with
consequent scarcity and increase of cost,
and (as a bye-product of this destruction)
agreat falling off in the waterpower
with which they manufacture the pulp.
For the present, the net result is a
stoppage of expansion, a scarcity of
supply and a rise in price. For the
future, it means a condition of positive
famine, with a tremendous curtailment
of publishing enterprise, unless a new
source of raw material speedily makes
itself manifest. Nothing further can be
hoped from wood. It has reached its
limit, and the nations of the world will
rise up in wrath against any attempt to
further rob them of one of their most
yaluable reserves of capital wealth,
May, 1909,]
Much disappointment has been caused
in the past by 1 too literal acceptation
of the statement that paper can be made
from any vegetable fibre. So it can, but
money can’t. To make both, several
important facts must be ever before
the fibre prospector. Paper is cheap,
must be cheap to fulfilits purpose. Any
serious increase in cost can only check
its utility and curtail ‘its production.
To secure the necessary cheapness, it
ean only be madefrom waste -from that
which has no value for any other pur-
pose whatsoever. Waste may be either
artificial, as with rags, or natural. My
definition of natural waste suitable for
paper-making is as follows: The fibre or
plant from which it is to be extracted,
must bea free gift of nature, growing
and reproducing itself naturally and
without cultivation, must not be of any
value to the spinner, ropemaker or even
(to any competitive extent at least) to
the feeder of cattle; and its removal
from place of growth must not imply an
attack upon any form of permanent
capital wealth. In the early days of
woodpulp, the wood from which it was
made no doubt fulfilled some of these
requirements. Itis because it did not
answer to them all that it has failed to
prove a permanent source of supply.
I have spent some years in investiga-
tion and experiment on this subject, and
have no hesitation in declaring that
South-HKastern Asia, including India and
Ceylon, isin a better position to deal
with this question than any other part
of the world, inasmuch as in these
regions is to be found a great store of
the wild fibrous grasses which best fill
the above requirements, together with
the cheap labour required to collect
them. Bamboo alone is capable of
supplying tens of millions of tons
annually without injury to its perma-
nence or reproduction. By what is
known as the acid process it yields an
excellent pulp for news or cheap’ book
paper, and at a cost considerably below
that of wood. Almost at our doors, in
Japan, there isa market for 20,000 tons
of it annually which is now supplied
from Europe ata great cost for freight.
My own investigations indicate that in
average bamboo jungle, a well regulated
system of cropping will yield 5 tons per
acre annually, or 2} tons of pulp werth
£7 to £8 per ton f.o.b.; and an area of
eight square miles would suffice to keep
a mill making 10,000 tons per annum
supplied in perpetuum.
Besides bamboo, there are several
species of annual grasses suitable, of
which the bharbar or sabai (Ischoemum
augustifolium) of Central India may be
taken as a representative, These are
423
Fibres,
capable of being treated by the alkaline
method, which involves considerably
less capital outlay than the acid process,
aad may be worked profitably on a much
smaller scale. The pulp produced is
equal to that of Ksparto and suitable for
high-class printing and writing papers,
and is worth about £9 to £10 per ton f.o.b.
Of course there are other factors
necessary to suecess, such as manutac-
turing facilities, percentage yield of
fibre, and other technical and scientifie
details which need not be dealt with in
an article intended to indicate the broad
lines, only, ofa possible new industry. I
shall be glad to enter into these points
with any correspondents desirous of
fuller information. Enough has perhaps
been said toecall the attention of State
authorities and land-owners to the
opportunity now offering itself to make
profitable use of the fibrous plants now
rotting away or being burnt in annual
fires on their waste lands and forests.

NOTES ON THE PRESENT POSI-
TION OF COTTON CULTIVATION
IN THE UNITED STATES.
A short account of the cultivation of
cottonin the United States, based ona
report made by the Inspector of Agri-
culture for British West Africa, was
given in a previous number of this
Bulletin (1905, 3. 334). The following
notes have been written by Mr. J. 8. J.
McCall, fomerly of the Agricultural Col-
lege at Cairo, who has recently visited
the cotton-growing States of America.
The cottons cultivated in the United
States include Sea Island, Upland, and
Egyptian varieties. These three classes
of cotton present distinet peculiarities
and special requirements, and are there-
fore dealt with in separate sections.
A.—SEHA ISLAND COTTON.
This crop forms less than one per cent.
of the total American cotton crop, but
Mibres.
is of great importance owing to its high
quality. It is grown to the greatest
dezree of perfection on James and Edisto
Islands, which lie to the west and south-
west of Charleston in the State of South
Carolina. The largest part of this crop
is grown on the coast line of South Caro-
lina, the interior of Georgia and North
Central Florida. The coast counties of
Georgia and Florida produce but little
cotton owing to the inferior character
of the soil and the absence of necessary
labour,
Crop Requirements.—Sea Island cot-
ton is more sensitive to soil and climate
than any other cotton. It is a maritime
plant, excelling in quality when grown
on light sand and gravel alluvia, not too
rich in humus, with free drainage, a
humid atmosphere, and in close proxi-
mity to the sea.
On the plantations of Messrs. Rivers,
Seabrook and Hinson, which are con-
sidered to be the three best plantations
on James Island, the cotton is grown
without a distinet rotation. Most of the
island plantations are divided into three
parts, seventy-five per cent. being de-
voted to cotton and twenty-five per cent.
to truck farming, 1.e. the cultivation of
vegetables, fodders, ete. The cotton
area is divided into two equal parts,
which grow cotton in alternate years.
During the fallow year a few farmers
grow leguminous plants, such as cow-
peas or velvet beans, but cereals are
never grown on the cotton land. Most
of the farmers prefer to leave the land
without a crop unploughed, allowing
weeds to grow among the old cotton
stalks, and using the field as a mule
paddock. Several farmers when asked
why they did not plough the land and
prevent the growth of weeds, replied
that ‘‘the sun hurts the ground when
exposed, and therefore we prefer a
covering of vegetation in summer to
bare fallow.” This is contrary to expe-
rience in Egypt, where the best crops are
obtained after a summer bare fallow.
Much of the island-grown cotton never
enters the market, but is sold privately
to lace manufacturers (mostly French),
at very high figures, Is. 8d. to 2s. 11d.
per pound frequently being paid for
choice crops.
In planting Sea Island cotton, 5 feet
is generally left between the rows and
22 inches between the plants. Planting
commences in March; harvesting begins
in the latter part of August and cop-
tinues till December.
The island-grown cotton is much
superior to the mainland crop. The
interiority of the latter is due to hybri-
424
MAY 1909.]
disation with Upland cotton, which is
grown in close proximity to it, and
also to the lack of humidity in the
atmosphere.
The mainland cultivators of Sea Island
cotton say that their Sea Island crop
is superior to their Upland crop when
the season is warm and rainy, and vice
versa when there is drought. The
mainland-grown crop is shorter and less
lustrous than the island cotton; the
best results are always obtained by
growing it from island-grown = seed.
During the present year the island
cultivators have formed a union to pre-
vent the sale of their seed, as they say
the increasing production of mainland
Sea Island cotton is affecting their
prices. The Department of Agriculture
at Washington have been 1efused seed,
which they much regret, as they have
no type of this cotton which does not
degenerate on the mainland. This is a
very narrow policy, and will probably
benefit Egyptian cotton growers more
than American growers, as the lower
grades of Sea Island, such as that grown
on the mainland, can be replaced by the
higher grades of Kgyptian varieties.
Possible Eautension of Sea Island Culti-
vation.—It is considered by many that
there is very little possibility of extend-
ing the Sea Island cotton industry in
America, the principal reascns being
that the cost of labour is very high, and
that the crop gives but small returns
when planted under other than the best
conditions. It is more profitable to
grow ordinary Upland in most districts,
as itis far more certain to yield a crop,
especially in seasons of drought.
Selection and Manuring.—The island
cultivators are firm believers in select-
ing and manuring their cotton, although
they object to a mixed rotation. Hach
of the island plantations visited had its
breeding and selecting plot, and there
is little doubt that the high quality of
Sea Island cotton is to a large extent
the result of prolonged selection in com-
bination with the admirable natural
climatic and soil conditions of the
islands. The planters are a superior
class of men, and exercise great care in
growing and harvesting their cotton.
They commence manuring the land,
when farmyard manure is available. as
early as November, by applying twenty
loads per acre on the surface between
the old ridges. Asa general rule, plough-
ing commences at the beginning of
February, when 1,000 to 1,200 lb. of
cotton-seed are applied between the old
ridges, if no farmyard manure was
available for application in November.
This seed is coven:d by splitting the

old ridges with the plough; most of it
decays, but any which germinates is
destroyed in subsequent ploughings. In
this practice the island cultivators con-
firm Egyptian experience, as they find
large late applications of slow-acting
organic nitrogenous manures interfere
with germination and retard ripening.
It is generally considered that all blooms
which appear after the first week of
September never mature, as they are
checked by cold or frost.
The first ploughing is deep (12 inches
when possible) and subsequent plough-
ings shallow. The first deep ploughing
encourages deep rooting, making the
plants more drought-resisting. The shal-
low ploughings give fine surface “ tilth,”
which is so necessary for germination
and rapid early growth.
When the soil is ready for ridging a
dressing is given, either in the drill or
on the flat, consisting of 600 lb. of
Peruvian guano and 50 lb. of potassium
sulphate per acre, and after germination
50 lb. of nitrate of soda are applied.
By this treatment, combined with
judicious selection, Captain Rivers of
James Island raises the finest Sea Island
cotton. The 1906-1907 crop of 419 lb. of
lint per acre was sold privately toa
French firm at 2s. 6d. per lb., or a gross
return of over fifty pounds sterling per
acre.
Marketing and Shipping.—Railway
Rates.—The island-grown crop is market-
ed in bags 73 feet long by 23 feet in
diameter, containing approximately 350
lb, of lint. The cotton is never com-
pressed in balesas this is considered
detrimental to the fibre. The crop is
practically all sold in Charleston, and
forms 385 per cent. of the cotton marketed
at that port, selling at from Is. 3d, to 2s.
6d. per Ib.
The mainland Sea Islaud, which is by
far the larger crop, is principally
marketed and shipped from Savannah,
the largest port on the Atlantic seaboard
of the cotton-belt. This cotton, like
Upland cotton, is sent trom the farms
to the cotton factors in uncompressed
bales of between 400 and 500 lb. The
factors take samples (from 2 to 5 Ib.)
from each bale, and expose them in their
sample rooms for sale, the price being
fixed by the grade and the cotton-
exchange fluctuations. The charge for
factoring varies from 4s. 2d. to 6s. 3d.
per bale, irrespective of class, species, or
value of cotton. This charge covers
insurance for the first fortnight the bale
is in the factor’s hands, but, if held over,
an extra charge of 2s. ld. is made for
storage.

B.—UPLAND COTTON,
I. Short-stapled.
Upland cotton is the principal cotton
of commerce, and is very extensively
cultivated in every State of the
American cotton belt.
The principal Upland Cotton States
are—South Carolina, Georgia and Ala-
bama, on the east side of the Mississippi ;
and the eastern half of the immense
State of Texas on the west side of the
Mississippi. It is considered that
Georgia and Alabama grow the best
short-stapled Upland, one of the best
varieties in this country being ‘‘ Cook’s
improved.” The soil of Georgia and
Alabama is red and rich in iron, much of
it being light and specially suitable for
fruit-growing, which is an important
industry in those two States. This soil
responds to liberal manuring, but large
areas are producing under 100 lb, of lint
per acre, owing to continued cotton-
planting without fallowiug, manuring,
or growing leguminous crop. This is
especially noticeable on negro farms,
where the farming is ofa very poor
class. Under normal conditions Upland
cotton never attains the height of Sea
Island or Kgyptian, and on some of these
impoverished soils the plants do not
exceed 18 inches, although remarkably
well fruited considering the poverty of
the soil. In Alabama and Georgia sur-
face mulching is firmly believed in, and
in dry weather the fields are treated
Mibres.
with the mule cultivator once a week
when possible, the general practice being
the drier the weather the more frequent
the mulching. In some parts of Georgia
and Alabama there is no rain for sixty to
eighty days in the months of June, July
and August, and the Upland cotton is
kept alive by repeated mulching.
During the tour through the States of
Georgia and Alabama few crops were
seen which would yield 400 lb. of lint
per acre, and many crops which would
give under 125 lb. This is a great con-
trast to the Delta of Egypt, where 500
lb. of lint or five cantars of seed cotton
is considered an average crop. Texas
cotton is inferior to Georgia and Ala-
bama cotton, and especially that pro-
duced in South-West Texas, which is
distinetly inferior to North and Central
Texas cotton.
It is interesting to notice the supe-
riority of the Upland cotton produced on
the east of the Mississippi to that grown
on the west. This is specially remark-
able, as Gossypium hirsulwm (the Up-
land cotton plant) is indigenous to
Mexico, and not to the east of the
Mississippi. The cause of the marked
inferiority of South Texas cotton is
generally attributed to the high tem-
perature; the same effect is seen in the
provinces of Upper Egypt, where Delta
cotton degenerates, producing harsher
and more brittle fibre.
Texas requires a storm-proof, early-
maturing cotton. There is much wind
at the time of harvest, and unless the
variety is storm-proof, much of the crop
is lost by falling from the open bolls.
Earliness is also necessary, as all late
eotton in Texas is destroyed by the
cotton boll-weevil. The best variety is
“Triumph,” which is a short-stapled
Upland cotton of good quality, gives
large yields, and is early-maturing and
storm-proof. At onetime, ‘‘ King ” cotton
was extensively grown in Texas, but this
variety has been largely superseded by
‘ Triumph,” which is superior in quality,
and yields a much higher percentage
of lint to seed. ‘‘King” cotton is useful
when circumstances prevent early plant-
ing, as it matures rapidly ; but it should
not be grown under ordinary conditions,
as the quality of its fibre is low and the
percentage of lint frequently under
thirty.
Markets, Transport, Labour, ete.—The
chiet ports for marketing Upland cotton
are Galveston and New Orleans. When
in New Orleans, several days were spent
at the “Cotton Exchange,” where, in
conversation with many prominent
factors and cultivators of this crop, it
was surprising to find that a very small
426
(May, 1909.
amount of attention is paid in classifica-
tion to quality of fibre, the grade being
fixed entirely ona basis of colour and
freedom from broken leaves or dirt.
Much of the late-harvested cotton is
greatly damaged by frost-strain, which
gives the fibre a characteristic rust
colour, thereby reducing its value by at
least 50 per cent.
The cultivators in the United States
consider the second picking superior to
the first, as the first picking always
contains a larger percentage of sand and
soil, the result of rain ‘‘spluttering”
the lower bolls. In Egypt, and where
cotton is grown under irrigation, the
first picking is always considered the
best, as the cotton does not suffer this
damage.
The system of handling Upland cotton
in America is disgraceful ; the bale-cover-
ings are of the cheapest material and
quite inadequate to protect the fibre or
hold it together. The amount of loss in
transit from the farm tothe spinner
must in many cases exceed 3 per cent. of
the original weight of the bale. The
compress sheds, docks, and railway sheds
are simply littered with cotton, and it
is stated that many of the cotton factors
pay their office expenses from the
samples they draw and the cotton
collected from the floors of their com-
press sheds and docks. The farmers are
largely responsible for this loss, as they
refuse to pay for better bale-covering.
The same thing would probably exist in
Egypt if the fellahin baled their own
cotton instead of selling it unginned to
the ginning firms, who supply bags for
the seed-cotton and bale the product
with a good cover after it has been
ginned. The advantage of this system
of handling the crop lies principally in
the cotton bale not being opened until it
reaches the spinner, whereas, in America,
bales are cut open, sampled and com-
pressed, passing through many hands
before reaching their final destination.
The scarcity of labour is the most
serious question connected with cotton
cultivation in the United States, and in
the last twelve years the cost has
increased by 50 percent, Itis extremely
difficult in many districts to obtain
adult male black labour ata dollar per
day asa minimum.
During late years railway work has
commanded much of the labour of the
country, and the ordinary farmer is
unable to pay from 6s. 38d. to 8s. 4d. per
day with board and lodging, which is
the common rate on railway construc-
tion work. Many of the farmers are
hoping that matters will be adjusted
when this class of work is completed,
but there is much work in lumbering
May, 1909.]
and also in towns which will employ all
available labour for many years to
come. When the men are getting such
high wages the women and_ children
refuse to work on the land. This crip-
plies the cotton industry, making farm-
ers unable to harvest their crops before
the frost comes, which injures much of
the fibre by discolouring it. There is
no suitable machinery for picking cotton,
and success in cotton cultivation in
any country is to a large extent de-
pendent on the efficiency and cost of
hand labour.
Picking costs 38s. lid. per 100 Ib. of
seed-cotton on an average or approxi-
mately £2 6s. per bale of 500 lb. of fibre
(1,450 to 1,500 1b. of seed-cotton yield 500
lb. of fibre),
There are considerable expenses con-
nected with handling cotton from the
time of harvest until it is sold. The
following calculation will show approxi-
mately the cost of picking, transport-
ing and marketing a 500-lb. bale of
cotton grown 200 miles from any of the
large ports, such as Savannah, New
Orleans or Galveston.

If the value of the bale is considered
as £10 8s. 4d. (5d. per lb.), the above
shows that the handling of the crop
costs the American farmer 335 per cent.
of the gross value of his cotton, the cost
of picking alone representing fully 22
per cent. of its gross value.
It is impossible to make the same
complete calculation for cotton grown
in Egypt, as the Egyptain farmer sells
his crop at the farm as seed-cotton to
the ginner, who bears the cost of
transport and ginning. The following
calculation will show the percentage
cost of labour to gross value in the
operation of picking.
Picking 1,50C lb, seed-cotton at 13
millimes per lb, =2850 mill.- £2 6s. 103d,
Thus the actual cost of picking is the
same asin the United States, but it is
wellto remember that an average picker
in America gathers 100 ]b. of seed-cotton
daily, whereas in Kgypt 60 Ib. is an
average. The difference isexplained by
the larger size of Upland cotton bolls,
which are more easily picked than
Kgyptian, Americans endorse this

Fibres:
statement, as experimental plots of
Kgyptian cotton cost the Agricultural
Department 2s. 1d. per 100 lb. more to
pick, and even then the pickers com-
plained about the difficulty of pulling
the fibre from the bolls.
The average value of Egyptian cotton
is 83d. per lb., and supposing, for the
sake of comparison, it was made into 500
Ib. bales, these would have a gross value
£17 14s, 2d.; therefore the picking re-
presents 13 per cent. of the gross value,
instead of 22 per cent. as is the case
with American Upland.
There isa more marked difference in
many of the other operations on the
farm, as the American negro receives
from 4s. 2d. to 8s. 4d. daily, and the
Egyptian fellah only from 10d. to Is. 5d.
The Egyptian fellah is the superior
worker, being more persevering and
industrious.
Cotton Seed.—At the present time
cotton seed is in great demand, and
finds a ready market at the ginneries,
which are principally worked by oil-
millers. Many of the farmers exchange
their cotton seed for cotton meal, as
the meal is more readily available as a
manure. The usual exchange in the
South is 2,000 lb. (American ton) of seed
for 1,200 lb. of meal; others sell the
seed at an average of £3 2s. 6d. per
American ton. Cattle are scarce in the
cotton belt on the east of the Mississippi,
but are plentiful in Texas and the west,
where large areas are still devoted to
cattle-ranching, The cotton farmer
never thinks of fattening cattle, but
many of the oil and ginning firms are
fully alive to the profit in cattle-fatten-
ing, and it is a common sight in the
west tosee the mills surrounded with
yards where cattle are fattened ex-
clusively on a mixture of cotton meal
and hulls. Hulls are sometimes pur:
chased as horse-food at £1 Os, 10d. per
ton.
The cotton belt would yield a much
larger cotton crop if there was more
mixed farming to supply organic man:
ure to the land. The exclusive use of
artificial manures cannot result in the
same fine physical soil conditions as is
produced by the application of organie
manures.
II, Long-stapled.
It is only within the last few years
that long-stapled Upland cottons have
becn cultivated. The crop is almost
exclusively grown in the valley of the
Mississippi, on the rich river bottom
lands. The Mississippi valley is the
richest part of the cotton belt, and
large yields are obtained without
Fibres.
manuring and with but little cultiva-
tion. Long-stapled cotton is more deli-
cate than ordinary Upland, and gives
much smaller crops, although the fibre
is distinctly superior in length, being
over 1 inch.
Small quantities of long-stapled Up-
land are grown in South Carolina and
Georgia, but the area is decreasing in
those States; in fact, throughout the
cotton belt the tendency is to give up
the cultivation of long-stapled Upland,
and even in the Mississippi valley it is
estimated that the area at present de-
voted to these varieties is only about
one-fifth of that of the last year. The
cause of this decrease of long-stapled
Upland cultivation principally lies in
the fact that the supply has exceeded
the demand for this staple, and the
present premium of 2 cents per Ib. is
not sufficient to compensate for the
smaller crop produced by these varieties
when compared with ordinary Upland.
Two years ago the premium was as
high as 7 cents, and it is considered
that when the premium is under 4 cents
a pound it does not pay to cultivate
this class of cotton.
There is little prospect of the produc-
tion of long-stapled cottons increasing
in the United States, as they are late
in maturing, and this is becoming the
most important factor in American
cotton cultivation, since all late cotton
in affected areas is destroyed by the
* eotton boll-weevil.” It is the general
opinion of American cotton experts that
all varieties of long-stapled Upland
cottons are allied to, or derived from,
«* Allen’s Long Staple,” two of the best
varieties being ‘“ Griffin” and ‘‘ Queen.”
In the United States all long-stapled
Upland cottons are spoken of as ‘‘ Floro-
dora cottons.”
C.—EGYPTIAN COTTONS.
During the past two years an average
of fifty-four million pounds of this staple
has been imported yearly from Kgypt,
and in 1907 the value of these imports
exceeded all previous records, and
amounted to over £3,300,000. The aver-
age price in the Boston markets was
about lld. per lb., or double the price
of ordinary Upland.
In view of the considerable value of
this import, the Department of Agri-
culture has been endeavouring to pro-
duce Egyptian cotton in the United
States to supply their home market,
The standard Egyptian varieties have
been experimented with, but the experi-
ments have been a total failure through-
out the main cotton belt extending from
Carolina to Texas. The chief cause of
failure is that there is insufficient heat
428
[MAy, 1909.
to mature the plants before frost sets
in. Experiments have met with more
success in the south-west, and especially
in the Colorado River region of Arizona,
where the deep alluvial soils, irrigation
and a longer and warmer summer ap-
proach more closely to the ideal condi-
tions of the Egyptian Delta,
In 1902 all experiments in the main
cotton belt were abandoned, and experi-
ments at Yuma in Arizona and Calixico
in California were commenced, Yuma
being the chief centre of experiment,
During the first three years these ex-
periments were practically a failure,
but after five years of acclimatisation
and selection great improvement was
effected, and now the Department hope
to grow Egyptian cotton for their own
use, although they will never produce it
in large quantities. The fibre produced
in Arizona is considered to be wanting
in colour, lustre and evenness of staple,
but is of good length and strength. ‘The
Department have had great diffizulty
in keeping it from crossing with Upland
cotton, and they therefore discourage
the growth of the latterin the neigh-
bourhood of the experiments. It is un-
likely that American-grown Egyptian
cotton will ever compete with Egyptian
proper, as the loss of lustre and colour
reduces its value for mercerising, a
process to which Egyptian cotton is
specially adapted. The American ex-
periments are interesting, as they clearly
demonstrate the value of acclimatis-
ation, and show that poor results ob-
tained in early trials with a new variety
do not necessarily indicate that this
valiety is hopelessly unsuitable for
introduction.
SOME DISEASES AND PgstTs.
Cotton suffers much more from diseases
and insects in the United States than
in Egypt, The diseases on the east of the
Mississippi differ to a remarkable degree
from those on the west, and two good
examples are those of the “Wilt Kun-
gus” of the east and the ‘Root Rot
Fungus” of the west.
_ Wilt Fungus (Neocosmospora vasin-
fecta).—This fungus enters the roots
from the soil, working its way into the
vascular system of the plant, and ulti-
mately killing if by preventing the
ascent of the sap. The fungus seems to
be able to exist as a saprophyte, as
there are cases on record where seven
years’ rest failed to free the land from
*' wilt.” Fungicides have no practical
effect, and the only method of control
is to grow resistant varieties which
have been produced by selecting healthy
plants from an infected area. Disease
MAy, 1909,]
resistant selection has been successfully
accomplished in the Sea Islands, where
‘“‘wilt” disease threatened to extinguish
the industry. The experiments were
conducted on the plantation of Mr.
Rivers, James Island, by the Depart-
ment of Agriculture, Washington. At
the time of the visit to this plantation,
less than one per cent of the plants were
affected with ‘‘ wilt” disease, although
many of the surrounding plantations
had over 25 per cent. of the crop
destroyed by it.
Root Rot Fungus (Ozonium omni-
vorum).—This disease is indigenous to
Texas, and there is little hope of its
extermination, as no cotton is able to
resist it. The root rot attacks lucerne
as well as cotton, and frequently destroys
25 per cent. of the cropeven when grown
for the first time on virgin soil. The
disease generally manifests itself when
the crop has reached the period of matu-
ration, and is characterised by rapid
decay of the root and that part of the
stem which is covered by soil. It is
easily distinguished from the “ wilt” as
the stem above the ground is never dis-
coloured, the disease never spreading
into the vascular tissue of the stem, as
in the case of the wilt disease of the
eastern section of the cotton belt. Crops
growing on clay and heavy alluvia
always suffer most, the disease being
favoured to a large extent by anzerobic
conditions. Deep winter cultivation and
soil aération are the most effective
remedies, and have been known to re-
duce the disease from 95 per cent. of the
total crop to 5 per cent. It is estimated
that 7 per cent. of the cotton grown in
Texas is destroyed by this disease.
Anthracnose (Colletotrichum gossy-
pii).—This is a disease found throughout
all the cotton fields of America, affecting
the bolls and rotting them when they
are practically mature. The severity of
the disease varies according to season,
being most active when there is much
rain and littlesunshine. The lower bolls
always suffer most, and a close-planted
crop, beset with weeds, is more liable to
injury than a wide-planted crop. The
disease causes most damage in the rich
river-bottom lands of Texas and Missis-
sippi, but is less injurious on the red
clays of Georgia and Alabama. The
principal remedies are rotation, drainage
and wide planting,
Cotton Boll-weevil (Anthonomus gran-
dis)—The cotton boll-weevil is the
greatest pest of the cotton belt. It was
first noticed in the State ot Texas in the
year 1894, and since then has travelled
northward and eastward at the rate
of fifty miles a year. In 1906, when it

reached the west bank of the Mississippi,
it was thought that the river would
prevent its onward march, but now in
1908 it is forty miles over the river on
the east side, and strongly established
in the State of Mississippi. It is caleu-
lated that seven years hence it will be
in every State of the cotton belt from
Texas to the Atlantic.
Should the boll-weevil reach the Sea
Island cotton, it will do more harm than
it does to Upland cotton, as it is much
more severe on the more delicate varie-
ties. It is even probable that the weevil
may exterminate the Sea Island cotton
industry, and that most of the island
farmers will turn their attention to the
cultivation of early vegetables for the
New York market. At the present time
‘‘wilt fungus” has caused many of them
to grow asparagus instead of cotton, and
market gardening on the islands is a
growing industry.
One large landowner in Texas, who
lets his land to negro tenants and takes
part of the crop for rent, informed me
that in 1904 three thousand bales were
produced on his estate, whereas, in 1907,
after the weevil reached the district,
three hundred bales was the total out-
put. The cotton boll-weevil has done
much to stimulate the Southern farmer
and lead him to improve his methods of
cultivation. It is probable that this will
result in the introduction of mixed
farming and rotations, and prevent con-
tinuous cotton-growing, which has ex-
hausted much of the best soil. It is of
the greatest importance that every
possible precaution should be taken to
prevent the introduction of the boll-
weevil into Africa.--Bulletin of the
Imperial Institute, Vol. VI., No. 4, 1908.
SISAL HEMP IN THE BAHAMAS,
From the Annual Report of the Curator
of the Botanical Gardens in the Baha-
mas (Mr. W. M. Cunningham, formerly
of Hope Gardens), we take the follow-
ing :—
“The export of sisal fibre for the
year shows a total value of £40,140,
The average selling price of machine
and hand-cleaned sisal fibre during the
financial year was 38d. per lb, The
most important industry is the raising
of sisal fibre, used for making binder-
twine, ropes, bags, matting, brushes,
&e. Its profit can be judged from the
prosperity of the Out Islands. Un-
affected by heat, drought, storm or in-
sects, the sisal crop is certain, and the
price is staple. The Bahamas fibre is

said to be of superior strength. Its
annual yield is variously estimated at
from £3 to £10 per acre.
“The estimated area under sisal culti-
vation is considerably over 25,000 acres.
The output exceeds that of previous
years, and the acreage is increasing,
especially in the Out Islands.
“The enormous trade already existing
in sisal, and the increasing demand with
which the production has not yet been
able to keep pace, the expansion of the
Canadian wheat-growing industry, for
which millions of pounds of binder-twine
are needed annually, and of late the
decrease in the output of Manila fibre,
all pond to encourage the planting of
sisal.
‘“‘Other countries are coming to the
front with this sisal fibreindustry, which
makes it more and more important that
no efforts should be spared to bring our
product up to the mark in quality. The
Hawaiian Islands, Porto Rico, Mexico,
and other countries are setting to work
with a will to develop a fibre industry ;
vast quantities of fibre are produced
and are coming forward for the Ameri-
can market.”
A good many years agoa plantation
of sisal hemp was established here by
Colonel Ward at Moneymusk, but it
was given up, owing to the difficulty
then of finding effective machinery
for dealing with the plant. At the
430
{[May, 1909.
present time, however, there are several
machines in the market that are said
to be thoroughly effective.
A small plantation has been again set
outin Vere, and, judging from the con-
fidence in this industry in other parts of
the world, we should think it will be
very successful, There is talk of another
small venture in Trelawny. There are
good stretches of land in Jamaica quite
suitable for growing sisal. This variety
of agave, as well as others, and also
Sanseviera, grow wild in the driest parts,
and are common. The most suitable
soils are light, dry, well-drained, on a
limestone foundation, and these are
common here, and once the plant is
extabbyshed, no dry weather can kill it
out.
This cultivation has made Yucatan,
the poorest endowed part of Mexico by
Nature, perhaps the richest in actual
wealth. The export of fibre from
Yucatan is about 600,000 bales, of a value
of £3,500,000. The importations into
the United States in 1905 amounted to
§,265,819 lb., at anaverage ol £35 per ton.
The price per ton, which was £15. Os. 3d.
in 1904, has steadily increased every year
until now it ranges from £35 to £37 10s.
per ton. On dry lands plantations of
sisal hemp could be easily and cheaply
established, and crops of cotton taken
off between the rows when the sisal
plants were small.—Journal of the
Jamaica Agricultural Society.
EDIBLE PRODUCTS.
THA MANUFACTURE IN
DARJEELING.
THE PROBLEM OF QUALITY.
The old adage that tea is made on
the garden and spoilt in the factory is
often quoted in connection with Dar-
jeeling manufacture, but in some cases
it might be more correct_ to apply the
saw of the silk purse and the sow’s ear.
Analysing the results of the elaborate
experiments conducted of recent years
with the object of discovering the causes
of quality in tea, itis now generally re-
cognised that, as far as Darjeeling is con-
cerned at all events, we areas far from the
true explanation as ever, :for we are con-
fronted with sucha mass of contradictory
evidence that the planter may well plead
confusion rather than enlightenment.
Much theoretical advice has been forth-
coming, but the practical methods recom-
mended for the improvement of quality
have not met with approval from the
majority of those planters in Darjeeling
who have given them atrial. In fact these
methods are in many cases so diametri-
cally opposed to those practised on
estates yielding teas of the highest class,
that there is grave reason for the belief,
often expressed, that quality cannot be
controlled.
The supply of Darjeeling teas being
such asmall one, comparatively speak-
ing, there is usually a consistent demand,
and they can generally be relied upon to
fetch a remunerative price. To the
outsider who, pussessed of no practical
knowledge, peruses the weekly market
reports, it would doubtless appear that

prices being constantly realised for
representative invoices. This, needless
to remark, is far from the truth. The
comparative prices of Darjeeling and

often a very wide one, but it must be
remembered that the outturn per acre
in the hills is often only 2$ to 3 maunds
per acre, whereas in the plains, the
average garden, in even moderate order,
Wwul usually yield at least double that
amount. The expenditure of an estate
is based upon its area, and it therefore
becomes obvious that the cost of the
crop varies directly according to the
yield per acre. Thus while teas from
Sylhet and the Dooars are often laid
down in Caleutta at anything from
as. 2-6 to as. + per pound, there is hardly
a garden in Darjeeling capable of placing
its crop on the Caleutta market at less
than as 6-9 per pound, and on many
estates the cost is even higher. The
difference in outturn between hills and
plains estates may be directly attributed
to climatic influences.
There is no getting away from the
fact that the colder climate of the hills
is antagonistic to luxuriant growth on
the part of the tea bush. This is
evidenced by the slower growth and
smaller leaf obtained. Further, liberties
which may be taken with impunity in
the plains quickly produce a deleterious
effect in the hills, and a falling off in
crop is often noticeable after even one
season of severe treatment. The Dar-
jeeling planter therefore finds himself
compelled to consider details to a much
greater extent than his neighbour in
the plains, whose work is much more of
general supervision and less of individual
bush treatment.
AN ASTONISHING FACT.
It would perhaps astonish the unini-
tiated to learn that the highest quality
is obtained in Darjeeling from leaf
which is actually in an unhealthy
condition, that is to say leaf which is
suffering from greenfly blight. This
blight generally makes its appearance
in June, when the best teas are
turned out, and it is not uncommon
to hear a planter bewailing the fact
that he has not been visited by
this friend to quality during the current
season. Atthe same time, for reasons
unknown, there are gardens in the hills
which appear to be unable to yield a tea
of more than medium quality, greenfly
or no greenfly, and this is where all in-
vestigations into the causes of quality
have hopelessly failed. In these cases,
soil conditions and the jat of bush are
often identical with those of adjoining
gardens of the first rank, and yet these
431
Hdible Products,
‘““sow’s ears” obstinately refuse to be
transformed into “ purses” of even the
most moderate deseription. Their mana-
agers are therefore confronted with the
necessity of keeping their bushes in the
highest possible state of health, in order
to obtain as great a yield as possible.
Inacasual trip through the District
one would imagine that the pioneers of
the Tea Industry in Darjeeling took
almost special pains to build their
factories in the worst possible position.
It is not too much to say that had
suitable sites been chosen, there is not a
single gardenin the hills which might
not have had the benefit of water-power,
to the saving of its fuel and the reduc-
tion of its expenditure. Asa matter of
fact, however, gardens where machinery
is water driven are in the minority, and
the natural result is the present-day
ery of shortage of fuel with all its atten-
dant evils. Where water is available,
the turbine has in many cases superseded
the older-fashioned water-wheel as being
less cumbersome and more effective.
The wear and tear on bearings is, how-
ever, very severe Owing to the action of
the extraordinarily fine grit present in
hill water, and the life of a turbine cannot
in all probability be considered to be so
long as that of the water-wheel, which,
if made of iron, is practically everlasting.
Of late years, electricity has been
employed on some gardens close to the
Darjeeling Municipal generating station
with the best possible results. The
installation is by no means excessively
expensive, and the power, while not
actually cheaper than fuel, is natur-
ally of immense profit to the estates so
fortunate as to have obtained it, allow-
ing as it does such a very great saving
of forest supplies.
Quality being always the aim in Dar-
jeeling, a great deal naturally depends
upon proper factory supervision, for,
given good leaf and adequate machinery,
a very slight falling in any of the pro-
cesses of manufacture may veritably
make or mar. This supervision is in
mary cases complicated by the fact that
bungalows are builtso far away from
factories, but the Darjeellng planter is
lueky in the services of the Nepali, who
in many cases may be relied upon to
obtain the best results solay for his own
satisfaction.
SUPERVISION AND CLEANLINESS.
Absolute cleanliness throughout the
factory is of course the first essential,
and this is fully recognised in the hills,
no expense or trouble being spared to
ensure the impossibility of any taint
being imparted to the tea from the time

when it enters the factory to the time
when itis despatched from the local sta-
tion to its final destination in Calcutta or
London. Wither, fermentation and
firing all play important parts, but the
best conditions appear to vary according
to elevation, and it is therefore im-
possible to lay down any hard and fast
rules.
THE “SOLE UNIVERSAL NEED.”
The sole universal need is a good even
wither, which is absolutely necessary in
order to obtain the best results. This,
however, is not a matter of such ease as
it might at first sight appear. In the
earlier months of the season, the atmo-
sphere being as a rule fairly dry, readily
absorbs the surplus moisture in the leaf.
and a satistactory wither is purely a
matter of proper spreading on the
factory racks. In the rains, on the
other hand,it is at times quite impos-
sible to obtain the proper amount of
evaporation, and planters are perforce
compelled to accept conditions which are
prejudicial to quality. These coupled
with the ranker and more sappy growth
then obtaining at most_ elevations,
usually cause a loss of flavour, also
affecting the colour of the fermented
leaf.
The Scientifie Department of the
Indian Tea Association were recently
busy with the subject of rolling, but in
spite of their report, the best Darjeeling
teas appear to be almost universally
rolled for one and a half hours, a redue-
tion in the time devoted to this oper-
ation having usually yielded disappoint-
ing results. Itis now generally accept-
ed as a fact that a relatively cool
fermentation suits low elevations; a
warm fermentation is proper for higher
levels.
The aim of the manufacturer is to
obtain an even, bright coppery colour,
but owing to almost daily variations
of leaf and climate, this is rarely
achieved to perfection. From time to
time we are confronted with some
mechanical means claiming to surmount
all difficulties in this direction, but so
far nothing effective has been produced,
and it is doubtful whether, for the hills
at all events, any mechanical aid can be
evoked to deal with such wide variations
as those above mentioned.
Firing is a delicate process, and the
many types of dryers on the market
each has its own adherents. Where a
full plant is available, the Updraft
Sirocco appears to be the most popular
dryer in the hills, especially when fitted
witha multi-tubular stcve. The eco-
nomy in fuel shown by these dryers is of
the first importance nowadays, and the
[MAyY, 1909.
fact that every tray can be separately
examined naturally appeals to the
seeker after quality, especially when he
is so fortunate as to havea thoroughly
experienced staff. Where large crops
are turned out, it is common to see the
leaf put through an automatic machine
and dried to twelve annas, to be finished
off on hand dryers or over chulas. Many
planters firmly adhere to the practice
of finishing in the old fashioned manner
over charcoal, and itis noticeable that
most of the estates that dry in this
manner produce teas of merit. It is
claimed, and it would appear with some
justice, that teas thus treated keep
longer and are of a more mature flavour
than those solely machine dried.
To be of stand-out-quality, Darjeeling
invoices should show a maximum of
strength and flavour in their liquors,
which should also be brisk and pungent.
The infused leaf should be of a bright
even, coppery colour, and the liquors,
when cold, should show ‘“ creaming”
power. The appearance of the dry leaf
is a more or less secondary consideration,
except that the most particular care has
to be exercised to keep the various
grads absoluteiy even. Fannings and
Dusts should be absolutely free of grit
of any kind, and it is to be feared that
sufficient attention is not always given
to this point.
AN IMPORTANT POINT.
With the strong demand for Darjeel-
ings at present obtaining in Caleutta, it
is of importance that planters should be
brought as much as possible into direct
touch with buyers, and it would probably
prove of immense benefit to the industry
if buyers made a point of visiting the
district annually at the beginning of
the season to invite the attention of
planters to the class of manufacture
most suited to the markets they re-
present. It is of the utmost importance
to all concerned to bear in mind that
the greater part of the Darjeeling crop
is nowadays taken for Russia, and that
po efforts should be spared to maintain
and extend the hold that has been
obtained there after so many years of
depression.—Indian Agriculturist, Vol.
XXXIII., No. 11, November 2, 1908.
PADDY.
Copy of an article on “ Paddy” extracted
jrom the “ Handbook of Agriculture
jor Burma: — f
Paddy is the most important and
most valuable of our grain crops, and
occupies in Burmaa much larger area
than all other crops together. The main
varieties of paddy are(1) Kyaukkyi (bya
May, 1909,]}
or abart and lonbyu). (2) _Kyaukkyin
(red and white), (8) Mayin (red and
white), (4) (lawthut, (5) yahaing, (6)
akare, (7) shangale, (8) lonbu, and (9)
ngaya.
Clay soils which may be easily flooded
are best adapted to paddy: practically,
however, nearly every kind of land will
produce fair crops of paddy if in good
condition, unless when the climate is
really unfavourable for the purpose.
Hanthawadd, Thongwa, Pyapon, Am-
herst, Thaton, Pegu and the delta
Districts in Lower Burma and Kyaukse
in Upper Burma are the best districts
for paddy. Comparatively little paddy
is grown in some districts of Upper
Burma.
The time of sowing is very much a
matter of local experience and is more
or less regulated by the weather and
the fitness of the ground. In _ the
Kyaukse district of Upper Burma the
Kyaukkyi crop is usually sown in
Nayon or Wazo (about June), the Ky-
aukkyin in Tabaung or Tagu (about
March), and the Mayinin Thadingyut
or Tazaungmon (about October).
Inthe Amherst and Thaton Districts
of Lower Burma paddy is usually sown
iu Nayon, except yahaing. The quan-
tity of seed to he sown to the acre
varies greatly. That quantity is best
which yields the largest crop, and the
solution otf that point rests on the
experience of the individual cultivator.
The answer depends ou many consider-
ations: the quality and condition of the
land, the climate, the goodness of the
seed, and the mode of sowing. One
basket of seed per acre may suffice where
the conditions are all favourable, as is
the case in the localities of Bilugyun
and Zaya in the Amherst District of
Lower Burma; and even 24 baskets of
seed may not be too much per acre, under
the circumstances, as is the case in some
parts of the Kyaukse district of Upper
Burma. Whatever be the quantity, it
is desirable that the ground be fairly
occupied by plants when the growth
commences. More seed willbe required
when the broadcasting method is adopt-
ed, and less seed when the seedlings are
to be transplanted from a nursery.
To economize the quantity of seed
required, cultivators are advised to sow
the seed in lines at regular intervals,
say, at2 or 3inch intervals, and set the
seed with a measure just big enough
to sufficiently set seeds on each line.
An ordinary cultivator who is used to
the prevailing method of scattering seed
in broadcast may perhaps imagine that
this method of sowing in lines would
not pay so well, for the reason that the
55

Edible Products.
entire surface of the land selected for
the seed-bed would not be covered by
plants; but then it should be remem-
bered that all seeds do not germinate
when broadcasted. The principles of
scientific theory show that the method
suggested would give a better result,
for the simple reason that the seed is
equally distributed, and thus, after
germination, each plant has a sufficient
space of ground for expansion and can
draw nourishment from the soil with
greater tacility, with the result that it
becomes a good plant for transplanting.
In the best districts of the country
a quarter of the entire holding is re-
served for sowing seed at the rate of 1
to 2} baskets per acre of the holding.
The cost of sowing seed may be roughly
caleulated at from Rs. 5 to Rs. 6-4-0 per
acre in Upper Burma,and Rs. 3 to Rs.
3-8-0 per acre in Lower Burma, includ-
ing the market value of the seed at the
time of sowing and the cost of plough-
ing.
When seeds are sown in the districts
of Upper Burma where rainfallis scanty
and where lands are usually irrigated
the cultivator should take care that he
maintains adepth of 3inches of water
in his seed-bed, drawing out the stale
water and irrigating with fresh water
oncein 10 or 15 days if the water is
allowed to remain too long in the seed-
bed, the rise of temperature will cause
the young plants to perish ; but in Lower
Burma since sowing takes place at the
proper time of the rainy season this
precaution is not always necessary.
The quality of the seed should be
another consideration in sowing; for
choice grain, if achange has been got
from a different soil, will produce plenty
of plants with less seed than in other
circumstanees. Every cultivator should
prefer bright, sound, plump, and well
cleaned seed; and certain varieties have
hereditary qualities which it is well to
respect. A great deal more than the
usual care should be taken in the selec-
tion of proper seed. Cultivators should
always select the ripest and best seeds
of the best ears of the best plants at
hand, and cultivate them with extreme
attention to every circumstance that can
improve their productiveness. Practi-
cally speaking there is no ‘pedigree’
paddy in Burma, but a ‘pedigree’ wheat
is well-known in England. In order to
establish a ‘pedigree’ paddy cultivators
should endeavour to follow the afore-
said hints which are based on the various
experiments made by the leading scienti-
fic men of Great Britain. Itis a well-
known fact that the byat variety of
Kyaukkyi paddy from the neighbour-
hood of Shwelekwin in the Myittha
Edible Products.
township of the Kyaukse district and
the Billugyun and Zaya Townships of
the Amherst district is superior to the
grain of any other localities. Ripest
and best seeds, of the best ears, of the
best plants, if possible of the localities
known to yield good grain should be
selected for sowing and should be sown
with extreme attention to every circum-
stance that can improve their pro-
ductiveness and thus establish the un-
known ‘ pedigree’ variety.
In connection with this subject the
cultivator might advantageously note
that short straw sorts are desirable for
highly cultivated lands, and early ripen-
ing sorts for late growing localities,
while hardy sorts are suitable for
hazardous climates.
After the seeds have been set with
due precaution regarding water in the
nursery, the land intended for trans-
planting should be properly levelled so
that the irrigated or rain water may
nourish the plants equally. The seed-
lings are generally ready for trans-
planting in about forty-five days after
the seeds have been set; but the time
for transplanting should be known from
the stenck of the mud; unless the mud
in the nursery shows signs of decompo-
sition and gives out a stench, the
seedlings should not be transplanted.
It should be remembered, however, that
the seedlings of Kyaukkyin paddy must
be transplanted within forty-five days,
for if they are not transplanted and
allowed to remain in the nursery after
the torty-fifth day they will not give
a good return.
The seedlings should be transplanted
in lines at 6 or 8 inch intervals, and at
the same distance from each other, so
that each plant may have a sufficient
space of ground to grow upon. If prefer-
able, seedlings may be transplanted in
triangles at the distance of 6 or 8 inches
from each. This is preferable in dry
localities, where irrigation is the only
source of water-supply, as it will be
found easier for withdrawing the stale
water. Whether the seedlings are trans-
planted in squares or triangles, it must
be remembered that the best returns
are only attainable when there is prac-
tical approach to giving every plant a
clear space of ground to grow upon.
When each plant is in its own square or
triangle it has room to expand and draw
nourishment from the soil and the air
with greater facility.
The usual time for transplanting in
Upper Burma for Kyaukkyi isin Wazo
or Wagaung (about July), for Kyaukkyin
in Kason or Nayon (about May), and
for Mayin in Pyatho or Tabodwe (about
January).
434
[MAY 1909,
The climate of Lower Burma being
generally damp after the seeds are set
so much precaution is not necessary, and
the only hint required is to always trans-
plant when the mud begins to give
forth a stench on or about the forty-
fifth day after the setting of seed.
The costof transplanting may be rough-
ly calculated at Rs. 4-8-0 or Rs. 5 per acre,
assuming that four men at 8 annas each
are required to take out the seedlings
from the nursery and eight women at 6
annas each to set the plants.
After the seedlings have been trans-
planted care must be taken to maintain
a depth of at least 2 inches of water in
the first month and 6inches from the
second month until the grains show
signs of hardness, butit is not necesary
to change the water as was the case
while the plants are in the nursery. As
soon as the grains show signs of hardness
every particle of water should be with-
drawn and the crop left alone until ready
for reaping. In Lower Burma the rains
generally cease when paddy grains come
to maturity, so that there is no occasion
for drawing out water asin the ease of
the irrigated districts of Upper Burma.
In Upper Burma the Kyaukkyi crop
is reaped in Pyatho (about December),
Kyaukkyin in Wagaung (about August),
and Mayin in Taga (about April). In
Lower Burma the shangale crop is reaped
in Tazaungmon or Nadaw (about Novem-
ber), if seeds are set in Nayon (about
June), and Kyaukkyi in Pyatho (about
January). The cost of reaping and
threshing the grain may be roughly eal-
culated at Rs. 4-8-0 or Rs. 5 pe. acre,
assuming that four men at 10 annas per
head per diem are required tuo reap and
tie into 240 sheaves, three carts to
convey the sheaves to the homestead
or threshing-ground at 4 annas each,
two bullocks at a ccst of one rupee to
tread out the heap of sheaves, and
one man at 8 annas for winnowing.
In Upper Burma the yield of Kyauk-
kyi crop trom an acre of first-class
land is about 50 baskets, from second-
class land 35 baskets, and from third-
class land about 25 baskets. The yield
of Kyaukkyin from an acre of first-
class land is about 60 baskets, and
second-class 40 baskets, and from third-
class about 380 baskets. The yield of
Mayin from an acre of first-class land
is about 50 baskets, from second-class
land 380 baskets, and from _ third-class
land about 25 baskets. In Lower Burma
an acre of first-class land yields from
40 to 60 baskets, an acre of second-class
land about 30.to 35 baskets, and an acre
of third-class land from 15 to 25 baskets,
May, 1909.]
In former days cultivators scarcely
manured their lands for paddy cultiva-
tion, and, although they do now, the
quantity is scarcely sufficient. The
manure should either be applied as
soon as a previous crop has been reaped
or kept in composts, and applied when
ploughing in quantities of from 175 to
200 baskets per acre of farm-yard
manure. The field should be ploughed
deeply in the manner laid down in the
chapter regarding operations.
If the ground has been throughly
manured and properly tilled no insects
are likely toinjure the plants ; insects
only attack plants when the plants are
not healthy owing to bad cultivation
or to the exhaustion of some particular
plant-fcod in the soil.
There are three kinds of insects
known to injure the paddy crop
from the first stage after seedlings are
transplanted until the whole crop
has been damaged, and no cultivators
appear to have done anything towards
their prevention :—
(1) Palanbyu (a variety of saw-fly) is
the size of half a grain of rice,
blackish in colour. with two wings
on each side, four legs, and a small
horn. They generally come trom
elsewhere just after the seedlings
are transplanted and suck away
the leaves until the leaves become
white and die away.
(2) Nga-myaung-yang (also a variety
of saw-fly) is dark in colour, as
big as a grain of rice, with 12 legs,
They generally form from the
plant just when the plants begin
to grow well, and just at the time
the particular plant-food required
is exhausted.
Sitpo (a variety of grub) is the
size of an ordinary louse, and is
white in colour. They also form
from the roots in the same way as
nga-myaungdaung. When crops
are damaged by any or all of
them the cultivator is reeommend-
ed to dust with lime while the
corn is still young and the insect
spread on it. Soot would prob-
ably do good, it being a fertilizer
as well as disagreeable to the
insects.

RIPENING OF TROPICAL FRUITS.
Some interesting investigations by
Mr. H. C. Prinsen Geerligs, dealing with
the chemical changes that take place
during the ripening of some tropical
fruits of Java, are reported upon in a
435
Edible Products.
paper lately published in the J/nterna-
tional Sugar Journal. The fruits dealt
with included the banana, mango, tama-
rind, and sapodilla.
Bunches of bananas, as is well known,
are generally cut from the tree inan im-
mature state, and when the fruitis hard,
tasteless, and unfit for food. After a few
days the edible matter becomes tender,
sweet, and well-flavoured, but againa few
days later the fruit is unpalatable, owing
to over-ripeness and decay. Some of the
changes that go on in these stages were
investigated by Mr. Geerligs.
A notable feature was the loss of
weight that takes place during ripening.
Twenty green bananas, kept in a cool
place, were found to have lost an
average weight of 8 grammes each at the
end of seven days. In another case, ten
green bananas of a smaller variety,
weighing originally 5025 grammes, lost
15°5 grammes in four days, and by suit-
able means it was shown that of this
loss, 2'°3 grammes were given off as car-
bon dioxide.
From a bunch of bananas, cut in the
immature state, a single fruit was ana-
lysed daily for a week, so that the
changes in progress might be observed.
At the end of the week the remaining
bananas were in a stage of over-ripeness,
The most prominent feature of the
ripening process in the case of the
banana was the rapid transformation of
starch into sucrose or cane-sugar. At
the first analysis of the unripe fruit, the
percentage of starch in the banana pulp
was 30°98, and of sucrose 0°86 per cent.
Two days later, thectarch had decreased
to 24°98 per cent., while the sucrose
present was 4°43 per cent. On the fifth
day from the first analysis, the banana
(almost ripe) contained 13°89 per cent. of
starch, and 10°5 of sucrose, while on the
following day there were present in the
fully ripe truit only 9°59 per cent. of
starch, but 18°68 per cent. of sucrose.
The percentages of glucose and fructose
also increase during ripeving, and in
the fully ripe fruit. In the over-ripe
bananas, the proportion of sucrose
shows a falling off (10°36 per cent.), which
is explained by the fact that inversion
of the sucrose into glucose and fructose
takes place. The latter two products
also undergo further breaking up, which
probably accounts in part for the large
amount of carbon dioxide formed in
after-ripening.
Mangoes also are usually picked when
unripe. At that time they are hard, acid,
and flavourless, but the after-ripening
process renders them tender and full:
flavoured in a few days,
Edible Products.
The chief features of the ripening pro-
cess with the mango are changes in the
proportions of starch, sucrose, and citric
acid, together with a loss in weight.
Five mangoes, which originally weighed
1,139°3 grammes, lost 18 grammes in
weight, when kept for three days in a
cool place. Of this loss, 4°558 grammes
consisted of carbon dioxide. As in the
ease of the bananas, a mango fruit from
a parcel having practically the same
initial maturity was daily analysed. As
a result, it was observed that the pro-
portion of starch present declined from
$°53 in the unripe mangoes to nil in the
ripe fruit, while on the other hand,
during the same period, the sucrose
increased from 2°57 to 12°27 per cent.
Later on the sucrose becomes hydrolysed
and split up into glucose and fructose.
Citric acid, whichis the only acid found
present in the mango, diminished from
1°31 per cent. in the unripe stage, to 0°10
in the ripe fruit. The acid is not neutral-
ized in any way during the ripening
process, but is destroyed as the result
of the respiratory process, and given
off chiefly as carbon dioxide.
Tamarinds were also dealt with, and
the composition of the pulp of these
fruits, in several stages of riperess, ex-
tending over a period of more than two
months, is given by Mr. Geerligs.
Starch was present in green tamarinds
to the extent of 3°33 per cent., but five
weeks later all the starch had been
transformed—not into sucrose—but into
a mixture of glucose and fructose.
During the ripening process, the pro-
portion of these two sugars present
increased from 0'40 and 0°33 per cent.
to 20° and 11°6 per cent. respectively.
The acid of the tamarind is tartaric acid;
of this, the total proportion present in
the green fruit is 4°85 per cent., and in
the ripe fruit, 16-4 percent. In ripening,
too, a large amount of water is evapor-
ated, causing the fruit to shrink con-
siderably within the pod. A good deal
of acid is consumed by respiration after
the tamarind has reached the stage of
ripeness.
Another tropical fruit, the ripening of
which was investigated, is the sapodilla.
Sapodillas are plucked tree ripe, in
which state they are green and hard,
and contain gutta-percha and tannin
dissolved in the sap, which render the
fruit unfit for eating. After keeping for
a short while, however, the gutta-percha
and tannin become insoluble, and the
fruit becomes full-flavoured and _pala-
table. In the ripe sapodilla, the coagul-
ated gutta-percha may be seen as a
series of white threads, while the tannin
is deposited as insoluble matter in
certain cells.
436
[May, 1909.
These changes constitute the whole
phenomena of 1ipening in the case of the
sapodilla. There is no transformation
of starch into sugar, since no starch
whatever exists in the fruit at any stage
of the ripening process. Further, the
amount of sugar present before and
after full ripening is the same.
It may be added that from the result
of experiments described in detail, Mr.
Geerligs comes to the conclusion that,
in the case of the banana and the mango,
the rapid transformation of starch into
sugar is one of the vital processes of
these fruits, and not a consequence of
the action of some enzyme or soluble
ferment.— Agricultural News, Vol. VIII.,
No. 176, January 23, 1909.
PLANTING SUGAR CANE IN CUBA.
The Cuban-American, published at
La Gloria, Cuba, in the interest of the
Cuban Land and Steamship Company, is
urging the new settlers in the country
to plant some sugar cane, and states that
since their last bi-weekly issue they had
reports of 85 acres additional being so
planted. It would seem that the dis-
position of the promoters and backers
of the town of La Gloria, which is
located on the north side of Cuba, is
to utilise cane as a prominent crop,
beginning inasmall way until the set-
tlers have become familar with the
business. lt is said incidentally that
because sugar is a good thing for the
colony, the Cuban-American is disposed
to push it along. Itadvises the planting
of some cane, even if it be but a single
acre, and says that it will cost about
$60 to clear and plant an acre in cane,
and that it will not need replanting for
at least five years, and out of these
five years’ work avery material profit
is expected, as well as a considerably
increased area in sugar cane. As soon
as the sugar cane is two to three feet
high, itis expected to shade itself and
keep down the weeds and to need practi-
cally no labour, excepting during har-
vest, all of which may sound a little
novel to Louisiana readers. It is ex-
pected that with the development of
cane culture in that vicinity a competent
sugar factory will be erected, and that
La Gloria will become a conspicuous
sugar centre.—Louisiana Planter and

large amount of information as to the
composition, value, and digestibility of
these fruits.
As is pointed out in the article referred
to, the term ‘nut’ isnot a definite one—
botanically speaking—but is applied
indiscriminately to a varietyof certain
fruits; or parts of fruits, and implies
a more or less hard, woody covering,
surrounding a meat or kernel. The
fact that nuts form a _ concentrated
class of food-stuffs, owing to their
general richness in fats and proteins—
the two most valuable of nutritive
constituents—is very evident from a con-
sideration of the tabulated results
of analaysis of a large number of differ-
ent kinds of nuts, given in the article.
Oil or fat is very commonly a prominent
constituent of nuts. The hickory nut
(Carya sp.) contains 67°4 per cent. of
oil, the Brazil nut (Bertholletia excelsa)
65 per cent., the candle-nut (A leurites
tribola), 61°7 per cent., the butter-nut
(Caryocar nuciferum), 61°2 per cent., the
walnut (Juglans regia), 60°7 per cent.,
the coconut 56°2, the almond 54-4, and
the ground-nut (Arachis hypogea) 438°5
per cent.
Several of the above, as well as
others, are also rich in protein or albu-
minous matter—that constituent of
foods which goes to form muscles or red
meatin the animal body. In the ground-
nut the proportion of protein reaches
29'8 per cent., while in the case of the
butter-nut the protein comprises 27'9
per cent, Other nuts rich in albuminoid
matter are the pistachio, 22°6 per cent.:
the Paradise nut of South America
(which resembles the Brazil nut in
appearance and _ flavour), about 22°2
per cent., the almond and the candle-
nut. each 21'4 per cent.; the walnut,
182 per cent., and the Brazil nut,
17-4 per cent. The proportion of
albuminod matter in the coconut com-
prises only 6°6 per cent.
Only a few of the commonly used
nuts contain a large proportion of
carbohydrate matter. Among these
the dry chestnut, with 73°0 per cent.,
ranks highest.
When it is considered that the propor-
tion of protein in an average beef steak
comprises 19°8 per cent., and of fat 136
per cent., that in Cheddar cheese the
protein percentage may be taken as 27°7
and the fat percentage as 36°8, and that
boiled eggs contain 12°4 per cent. of
albuminoid matter, and 10°7 per cent. of
fat, it will be seen that the food value of
nuts, as deduced from their percentage
composition of nutritive matter is,
generally speaking, a high one. This
food value is somewhat depreciated on

account of the fact that the nutritive
constituents, more especially the protein
matter, are not so easily digested as the
corresponding constituents of meat, but
the opinion is expressed by the writer of
the article that this inferior digestibility
is, toa large extent, due to imperfect
mastication of the nuts.
The flavour of nuts is to a large extent
due to the oils present, though in some
kinds there are also certain specific
flavouring bodies. The nut oils readily
become rancid, and the disagreeable
flavour of spoiled nuts is due to this
property.
The almond possesses a hydrocyanic
acid flavour, which is characteristic of
the kernels of peach stones, plum
stones, ete., and this might be expected
when it is remembered that the almond
is the dried kernel of an inedilble fruit,
which somewhat resembles the peach
in appearance, and is closely related
to it botanically. Most almonds are
mild-flavoured, though in the so-called
bitter almonds the glucoside which
yields the cyanic acid is more abundant.

CITRUS INDUSTRY FOR INDIA.
In the middle of last year the Italian
Government imposed an export tax on
citrate of lime and concentrated lemon
juice. This tax, which does not seem to
have proved a popular one, is variable
and may reach a maximum of 25 per
cent. Its immediate effect has been to
increase the price of the products
named, thus opening the door for out-
side competition. The exports of con-
centrated lemon juice from Italy to the
United Kingdom are substantial and
were valued at £28,926 in 1906 and
£23,225 in 1907, The trade in citrate is
more important, and it isestimated that
one-third of the total crop of lemons is
now used in the manufacture of that
product. In 1907, 23,000 pipes of citrate
were produced, each pipe containing
672 lbs., and as 100,000 lemons are neces-
sary to manufacture a pipe, it follows
that about 6,900,000,000 lemons were
grown in Sicily during the year under
notice. That will give some idea of the
extent of the trade, which, moreover,
seems to be a profitable one, as we see it
stated on good authority that while a
hectare (2°47 acres) of land yields an
annual] return of Rs, 23-6, the same area
in a first-class lemon grove ina good
season may produce fruit to the value of
Rs. 1,500. But what with the export tax
and the destruction caused by the earth-
quake, this trade will probably be

thrown back for years. When, for in-
stance, the earthquake occurred the
rice per Sicilian pound (12 ounces) of
emon oil, of which there isa very large
yieldin Sicily and an active demand in
ractically all countries, was about 3s.,
a heavy speculation quickly forced
it up to 7s. 6d., at which figure a fair
trade was done; later on the price rose
to 10s., and lots were eagerly bought
even at that high price, which, further-
more, led to wholesale adulteration. At
the present moment the spot price is
about 5s., but it, as well as the price of
other citrus products, may probably rise
again as the result of the cablegram
received this week stating that the ruin
of Messina has been completed.
As India is the original home of the
lime, the question arises whether the
time has not come when this country
might with advantage take its share in
the citrus trade, in which there is
always a good deal doing, and in which,
owing to climatic conditions, it is not
open toevery country to compete. The
cultivation of limes in Indla, says Sir
George Watt, if organised on a com-
mercial scale, would necessarily involve
full advantage being taken of each and
every profitable outlet, such as the pre-
servation of the fruit (fresh and candied),
production of lime juice, and the manu-
facture of perfumes and oils such as oil
of lemon, bergamot, neroli, etc. He adds
that the lemon tree begins to yield
when five years old, when 15 to 20 years
it gives 1,000 lemons, and when full-grown
may afford from 3,000 to 5,000. The
yield of such fruit per acre varies greatly,
but it is believed that careful cultiva-
tion will produce from 150 to 200 barrels
aunually, each barrel containing from
1,400 to 1,600 lemons according to the
size of the fruit. The citrus industry is
a simple one and is well adapted _ to the
kind ot labour obtainable in India. To
obtain lemon oil, the peel is soaked in
water for an hour or two and _ is then
pressed by hand overa sponge in order
to separate the oil. If, however, the
peel is to be candied, only half of the
oil is thus expressed ; otherwise as much
as can be squeezed out is taken and the
waste peel used as cattle fodder. The
yield of oil varies according to the
conditions of moisture. In_ localities
where the annual rainfall is from 60 to
100 inches, the citric acid content of the
juice of the fruit is high and the yield of
438
[May, 1909.
oil is low; but where the rainfall is
high—say from 1380 to 200 inches—the
citric acid content is low and the yield
of oil high. In practice, however, the
amount of oil obtained from the peels of
1,000 1ipe lemons varies from 0°7 to 1‘51b.
To prepare lime juice the puJp is pressed
between rollers and the juice so obtained
is known in the trade as “single” juice.
This juice is then boiled down till its
specific gravity equals 60 degrees on the
citrometer. Itthen forms a dark brown
rather syrupy liquid, having a specific
gravity of 1:24, and is known com-
mercially as ‘‘ concentrated ” lemon juice.
The manufacture of citric acid from
concentrated Jemon juice is also a fairly
simple matter. Whiting is mixed with
water and heated by steam in a wooden
vat provided with a revolving agitator,
The concentrated juice is then slowly
pumped in, care being taken that the
whiting is finally in small excess. The
precipitated citrate is washed with hot
water, treated with sulphuric acid, and
is finally granulated by evaporating
the moisture. This acid is chiefly used
by calico printers, butitis also largely
employed in the preparation of effervesc-
ing drinks and also in medicine.
There is reason to believe that limes
and lemons can be cultivated practically
in every district in India, and that a
large trade could be organised, parti-
cularly so if special arrangements were
made on board steamers for carrying
the ripe fruit in crates or ventilated
barrels, as it would be greatly injured if
shipped in the hold with mixed cargo.
But the manufacture of oil, concentrated
lime juice and citrate is independent of
such special arrangements and may be
commended as a suitable industry for
India asthe necessary plant—consisting
ofa hand mill, mill-house, two boilers,
boiling house, vats and still—may be
acquired at a _ total cost of about
Rs. 4,600. Itis recommended that the
factory should beso arranged that the
crushing house is on higher ground than
the boiling house, in order that the juice
may run by gravitation from the well to
the storage vats, from the vats to the
still, from the still to the copper boilers,
where it is concentrated, thence to
wooden or copper coolers and finally
into casks for shipment.—/ndian Trade

TIMBERS.
CONSERVATION.
During the past year public opinion
all over the United States has been
arvoused as never before to a realization
of the necessity for more careful methods
in the use of the sources of the material
wealth of the Nation—the great natural
resources, forests, waters, minerals and
lands.
First came the announcement that the
President was to call together the
Governors of all the States for a Con-
ference. Then for six months followed
what amounted toa campaign of edu-
eution. Newspapers and magazines vied
with one another in articles on Ccuser-
vation, and helped to work up an interest
that reached the point of action at the
Conference of the Governors held at the
White House in Washington in May,
The Conference of the Governors was
a gathering that will be remembered as
one of the noteworthy events in Ameri-
can history. It marks the beginning of
a new era in the economic development
of the Union, for only by the wise use of
its natural resources can the Nation
continue tu enjoy material prosperity.
Following . the re-appointment by
President Roosevelt of Water Ways
Commission, and its enlargement into
the National Conservation Commission,
there have been appointed by many of
the Governors, State Conservation Com-
missions to investigate the resources of
individual States and to co-operate with
the National Commission in devising
plans whereby the natural resources of
the Nation asa whole and of each State
and Territory may be properly developed
and wisely used.
In Hawaii continued economic pros-
perity depends in an unusually inti-
mate way on the right use of natural
resources. For this reason it was
especially appropriate that Governor
Frear should appoint, as he didin July
last, the Territorial Conservation Com-
mission of Hawaii. In personnel the
Commission is representative of the
interests involved. The Chairman is Mr.
Ralph S. Hosmer, the Territorial
Forester. Mr. W. O. Smith is the Secre-
tary of the Hawaiian Sugar Planters’
Association, made up of the plantations
that are now the largest users of water
in the Territory. Mr. Alonza Gartley is
Manager of the Hawaiian Electric Com-
pany, a corporation that takes a keen
nterest in harnessing water to do work
in another way. Mr. W. F, Dillingham,
Treasurer of the Oahu Railway and Land
Company, represents transportation in-
terests, and M. Jared G. Smith, late
Director of the Hawaiian Experiment
Station, and now Manager of the Kona
Tobacco Company, has long been re-
garded as the special exponent of
diversified industries. The three first-
named accompanied Governor Frear to
the Conference of the Governors in
Washington in May as his “advisers.”
The Territory Conservation Com-
mission of Hawaii made its preliminary
report to Governor Frear just prior
to his departure for Washington in
November. It is appropriate that the
report should be given in full in the
forester. Therefore, it needs no excuse
that a good part of this issue is devoted
to the report and to itsappendices. The
present report is preliminary. It is
expected that further facts and figures
will be submitted to the Governor early
in 1909, before the coming session of the
Territorial Legislature.
To this end the Commission is continu-
ing to collect data on various points
bearing on the recommendations made.
These, with the report, will be made
public in due course.—Hawaitian For-
esterand Agriculturist, Vol. V., No. 12,

NOTK ON THE POWELL WOOD
PROCESS FOR PRESERVING
TIMBER.
By R. S. Troup.
GENERAL.
This process, as is now well known,
consists in impregnating wood with an
antiseptic saccharine substance in order
to render it immune from rot and the
attacks of white-ants and other insects.
At the same time it is claimed that the
wood is hardened and completely sea-
soned, and warping and splitting are pre-
vented. Many woods are unchanged in
appearance by the treament, but some,
notably salat (Boswellia serrata), are
rendered more handsome in grain. In
India at the present time the beauti-
fying of wood, however, is of minor im-
portance, the chief desideratum being to
obtain a thoroughly satisfactory and
cheap method of rendering so-called “in«
ferior” woods proof against rot and
Timbers.
insects, so that the outturn of sleepers
and building timber may be increased.
EXPERIMENTS RECORDED.
2, It is unnecessary to enumerate the
various authenticated tests which have
been carried out with powellised wood
in the tropics. These are to be found in
hand-books issued by the Company and
obtainable trom their Agents, Messrs.
Killick, Nixon & Co., Bombay.
The writer has at present some powel-
lished deal under observation. It has
been down ina spot infested with white-
ants since 4th March, 1907, and has up to
date (17th December, 1908) not been
touched,
A piece of untreated deal was nailed
to the powellised piece when first put
down, and was totally destroyed by
white-ants in a few weeks. Another
untreated piece was recently placed
with the powellised piece and is being
rapidly destroyed.
Similar tests in other parts of India
confirm these results. A large number
of powellised and untreated pieces of
different Indian woods are now being
laid down, but it will be some time
before any results can be arrived at.
S eepers of various kinds of woods are
allso being tested on the railway in
Burma. Messrs. Mackenzie & Co., Bom-
bay, in 1906 carried out tests on powel-
lised woods to ascertain if it looses its
antiseptic properties if exposed to the
weather. Planks of poon and mango
were subjected for four nights and days
to steam forced on them by an exhaust
pipe, then a stream of water was direct-
ed on them for four days, and then the
wood was subjected to alternate rain
and sunshine in the monsoon, and was
finally cut up and placed in white-ants’
nests in three different places, along
with untreated wood of the same spe-
cies. The untreated pieces were quickly
440
[MAY, 1909,
destroyed, while the powellised pieces
remained vntouched.
It has, of course, not been proved that
the process will stand the test of time
in India, and that sleepers will remain
immune from destruction for many
years. The tests which have been carried
out, however, show that powellised
wood effectively resists white-ants for
the periods to which the tests have ex-
tended hitherto.
POWELLISING PLANT.
3. Powellising plant on an experi-
mental scale has been working at Bom-
bay for some time past. An installation,
capable of treating 150 tons of wood
per week, is approaching completion
at Bombay, and will be capable of
undertaking the impregnation of wood
ona larger scale.
The value of the process has been
recognised in Australia, where the
Western Australian Government has
recently erected large works. Other
extensive works have been completed,
or are approaching completion, in Syd-
ney, New Zealand and Tasmania. Ame-
rica and Germany have also arranged
to erect works, and other countries are
negotiating.
TERMS FOR ERECTING POWELLISING
INSTALLATIONS, AND Cost THEREOF.
4. So far as the results of tests show,
there would appear to be great scope
for extending powellising installations
throughout India and-Burma. This the
Powell Wood Process Co., Ltd., are
anxious to do if they get reasonable
support from Gevernment and from the
various railways.
The terms and cost of erecting and
working such installations will be sup-
plied in strict confidence to bona fide
enquirers personally or officially known
to the writer.—Indian Forester, Vol

MISCELLANEOUS PRODUCTS.
VEGETABLE IVORY,
By H. A. ALFrorD NICHOLLS, C.M.G.,
M.D., F.L.S.;
President of the Dominica Agricultural
and Commercial Society.
The plant which bears the seeds known
as vegetable ivory is named botanically
Phytelephas macrocarpa, and it has been
placed in an order, of which it is the
chief representative, called the Phytele-
phantine. It differs from the palms
only in its flowers, which have an indefi-
nite number of stamens, but some botan-
ists—considering the characteristic in-
sufficient to constitute a natural order—
have made the Phytelephantinze a divi-
sion of the Palme.
The tree is indigenous to Panama,
Columbia, and New Granada, and it has
received several colloquial names, the
chief of which is the vegetable ivory
palm. In those Spanish-American coun-
tries in which it mostly abounds, the
natives call it Marfil Vejetal,
The tree has a thick, rough, creeping
trunk, from the under surface of which
roots are given off. The leaves, which
erown the stem, closely resemble in
their size, shape, and disposition, those
of the coconut palm. The male and fe-
male flowers are borne on different trees,
acd the trunk of a male plant is always
taller and more erect than that of a
female.
The inflorescence of the male plant is
a simple, fleshy, cylindrical spadix,
about four feet long, with four or five
spathes, and crowded with flowers, while
that of the female plant, which also
forms a simple but much shorter spadix,
bears from six to seven flowers, pure
white in colour.
The flowers exhale a powerful perfume,
and this is moce especially the case with
the large white female flowers, which
are, however, few in number. The ripe
fruit consists of three portions, an ex-
ternal one which is dark, rough, hard,
and woody ; a middle one that occurs as
an oily pulp of a yellow colour and
sweet taste; and an inner portion—the
seed—which is the vegetable ivory of
commerce, The oily pulp is collected at
the right season_and sold under the
name of Pipa de Jagua in New Granada,
while the seeds are exported for use,
as their name implies, as a substitute
56
for ivory. The fruits grow from the
stem just above the bases of the leaves,
and they occur in aggregations of six or
seven. The natives of Columbia call
this collection of fruits Jagua, or Cabeza
de Negro, on account, no doubt, of their
resemblance in size and shape to a
negro’s head. Each fruit contains from
6 to 9 seeds, so that in one collection or
bunch of fruits there may be as many as
sixty seeds, or ivory nuts, as they are
commonly called. The seeds have a
rough crust, of a dark-brown or slate
colour, enclosing the white albumen
which at one end surrounds the small
embryo. The albumen, or the so-called
ivory, is of a dull opalescent colour, but
it becomes whiter and more opaque by
exposure to the light and air. It is
softer and less brittle than ivory, and
it is therefore much used as a substitute
for the more costly tusk of the elephant.
By chemical analysis the albumen of
the seed has been found to consist of a
combination of cellulose, gum, caseine,
ou and albumen, with some residual
ash.
The tree was first seen by the Spanish
botanists Ruiz and Pavon in the groves
of the hotter parts of the Peruvian
Andes, and it was described by them
under the name Phytelephas macrocarpa.
The following extracts from the memo-
randa of these botanists is of interest :—
‘The Indians cover their cottages with
the leaves of this most beautiful palm.
The fruit at first contains a clear
insipid fluid, by which travellers allay
their thirst, afterwards this same
liquor becomes milky and sweet, and
it changes its taste by degrees as it
acquires solidity, till at last it is almost
as hard asivory. The liquor contained
in the young fruits becomes acid if they
are cut from the tree and kept some
time. From the kernels the Indians
fashion the knobs of walking-sticks, the
reels of spindles, and little toys, which
are whiter than ivory, and so hard, if
they are not put under water—and if
they are, they become white and hard
again when dried. Bears devour the
young fruit with avidity.’
The tree, as far as I know, is not culti-
vated to any extent, the seeds being
gathered by the natives from plants in
the wild state. Large quantities of
vegetable ivory are obtained from the
banks of the river Magdelena, and are
exported from Panama to the home
markets,
Miscellaneous Products. 442 3
When a vegetable product is gathered
from plants not under cultivation, the
supply, from a variety of causes, must
of necessity be fluctuating, and, more-
over, the sources of supply are in
constant danger of being exhausted, as
was the case when cinchona bark was
alone obtained from the forests of the
Andes. There can be no question,
therefore, of the advisability of tropical
agriculturists turning their attention to
the cultivation of the vegetable ivory
plant, as they have already done in the
case of other economical trees. The
constant increase in consumption of the
article points to the success of such an
undertaking.
In Jamaica, in Trinidad, and in Domi-
nica, the plant would thrive along the
banks of the rivers and streams which
als r
tahoe yeh
run through many of the estates
thus a profitable crop might be obtained
from land which is now principally
occupied by scrub or a jungle of reeds.
Trees grown at St. Aroment, Dominica
were grown from seed sent from
Panama. The seeds germinated readily
and the plants were hardy, and they
have grown at the edge of a small
stream—which sometimes runs dry—
without any care or cultivation. In
suitable situations, therefore, they can
look after themselves, so that, beyond
the original small expenditure in raising
the plants and setting them out, nothing
else is required, and, in these circum-
stances, a plantation of ivory-nut palms
should be a very profitable property.—

HORTICULTURE.
WATER AND WATERING.
By J. J. Wiis, Harpenden.
Water is the medium by which the
soluble matters of the soil are conveyed
through the roots into the interior of
plants.
An important fact in the relation of
vegetation to moisture is seen in the
effect exerted by the humidity of
the atmosphere upon its temperature.
Without more or less vapour in the
atmosphere, the radiation would cool
the surface of the earth so rapidly as
to destroy thelife of all tender plants.
The principal part of the rays of the
sun pass through the air, even when
it is saturated with moisture, without
appreciably heating it; but the heat
radiated from the earth and every ob-
ject upon it is intercepted and absorbed
by the humidity in the air; the atmos-
pheric warmth is, therefore, clearly
related not only to the heat of the sun’s
rays but also to the moisture of the air.
Like the covering of a cold frame, the
moist air admits the light rays by day
and prevents the exit of the heat to
which they give rise at night. Hence
the clearest, driest nights are the coldest.
Also the driest regions, like the desert
of Sahara, have the coldest nights, and
the cold of high elevations is due to
the same course.
Professor Tyndall says:—‘‘The_ re-
moval, for a single summer night, of the
acqeous vapour from the atmosphere
that covers England would be attended
by the destruction of every plant which
a_ freezing temperature would kill.”
Humidity and temperature are, there-
fore, intimately connected.
Although the heat of the sun causes
evaporation from plants, its amount is
governed by the humidity of the air
and the velocity of the wind.
If the gardener could regulate the
moisture of the atmosphere surrounding
his crops, maintaining the precise condi-
tions for keeping up the proper evapor-
ation by applying water artificially and
only in circumscribed limits to their
roots, he could be assured of success.
While he may do so inhis green-house,
there are no means of regulating the
heat and moisture of the open air and
also of the soil. Itis for these reasons
that watering outdoor crops in very
hot weather is more often productive
of harm than of benefit.
When the earth is naturally mois-
tened by rain, the whole air is satur-
ated with moisture, preventing both a
too rapid transpiration from the leaves
and an undue evaporation from, and
consequent chilling of, the soil. If
watering is done at all, it should be in
cloudy weather ; but it is most frequent-
ly injudiciously practised in dry, hot
weather, and so circumscribed in extent
that it can have little or no effect upon ~
the atmosphere. The roots are tempo-
rarily excited, and the dry, hot air robs —
the plants of the moisture through the
leaves as rapidly as it can be supplied
by the roots. ee
(May, 1909,
— w=" =
As soon as the temporary supply is
exhausted, the plant not only returns to
its former state of suffering, but is left
more susceptible to injury than before.
If the watering is repeated, the emission
of rootlets near the surface is encour-
aged, and these grow merely to perish
again unless the water is continued.
Another injury may occur, as already
indicated, through the decrease of tem-
apa ture caused by the rapid evapor-
ation.
In very hot weather, during periods
of drought, vegetation is greatly sus-
tained by the moisture which is return-
ed to the earth in the form of dews;
and, in order that these may be most
beneficial, the soil should be deeply
stirred and continue in a mellow con-
dition upon the surface. When the soil
is puddled and compacted around a plant
by local watering, the amount of dew
will be less owing to the decrease in the
number of points of radiation presented
by the compact ball of soil; besides,
the diminished quantity is evaporated
from the impenetrable crust without
being able to reach the roots. If
watered, the earth should, therefore,
be stirred subsequently, or the watered
purine be covered with fresh, locse
soil.
443 Horticulture,
If practised at all, the watering should
in hot weather be applied to the roots
and to the foliage. Evening is the proper
time of day, unless in the exceptional
case of watering cold frames when frost
is apprehended. Itis then advisable to
water in the morning. The water
should not be much colder than the
surrounding atmosphere.
_ When there are facilities for moisten-
ing the whole mass of soil by irriga-
tion, that should not be neglected, for
its great benefits are undoubted. But
even then, unless the surface be so
densely covered with the growing crop
as to prevent it from being baked by
the sun, it would be best to allow the
moisture to reach the roots through
percolation from open channels _ or
drain pipes near enough to each other
ang kept full than to cover the soil with
water.
A crop supplied with a sufficiency
of soluble manure will suffer less
during drought than one inadequately
fertilized, and the latter will require an
abundance of water.
Mulching the soil prevents a too rapid
evaporation, and is therefore to be re-
commended with or without watering.—

Since my return to Ceylon, I have
received numerous enquiries on the
above subject, accompanied by applica-
tions for supplies of this possible enemy

I left England too early in the year to
enable me to bring out any of the insects,

have, however, made arrangements
for the collection and despatch of living
specimens as soon as_ they become
sufficiently common, I do not_ expect
me first consignment before June or
uly.
To prevent possible disappointment, I
wish to take this opportunity of making
it quite clear that the proposed in-
troduction is purely of an experimental
nature. When the insects first arrive,
it may be advisable to keep them under
observation, in captivity, for a_ time,
before any distribution can be made.
‘I would warn. expectant recipients not
to be too sanguine of beneficial results.
In the first place, the insect is a native
of temperate climates, and it is by no-
means certain that it will adapt itself to
a life in the tropics. Secondly, it is
more particularly associated with pine
trees, though it has been known to
occur in oaks and some other species of
trees. Moreover, its usual food consists
of the larve of boring beetles that breed
in dead and decaying wood. These con-
ditions are all very different to those
it will find on our tea plantations,
Under the most favourable conditions no
marked results can be expected for a
considerable time. Hven supposing that
the introduced insect is able to obtain a
footing in Ceylon, the increase at first
would be slow. There are many other

factors governing the relations between
a predaceous insect and its prey that are
not yet fully understood.
The opinion of several leading entomo-
logists to whom I applied were distinctly
contradictory. Some of them considered
that the Clerus was of an adaptable
nature and would probably be content
in this country, so long as the food
supply was abundant. Others were as
confident that the experiment was
foredoomed to failure. They all con-
curred in assuring me that the insect
was purely insectivorous, and that—
failing its natural food—it would die
out. Under these circumstances, and
seeing that the introduction would be
practically costless, I considered the
experiment to be worth a trial.
I gather, from correspondence con-
ducted by the Acting Hntomologist
during my absence, that this particular
insect (Clerus formicarius) was selected
for experiment on the strength of
reports made by Mr. Hopkins of the
U.S. Department of Agriculture. It
should be understood, however, that
Mr. Hopkins was endeavouring to find
a natural enemy of a pine-wood borer
living in America under conditions
practically similar to those found in
Northern Europe (the home of Clerus
formizarius). I append a summary of
these reports :—
1. Ata meeting of the Entomological
Society of Washington, held October
6th, 1892, ‘‘Mr. Hopkins gave an account
of a recent visit to Europe for the pur-
pose of studying certain Scolytide@ in-
jurious to pine trees. He had brought
back with him a large number of speci-
mens of the European Clerus fornvicarius
alive for the purpose of introducing
them into pine forests in West Virginia
infested by Dendroctonus frontalis.”
2. In an article on “Damage to
Forests by the destructive Pine Bark-
beetle,” (‘Insect Life,’ Vol. V., p. 188),
Mr, Hopkins remarks that :—“‘By corre-
spondeuce with Mr. Hichoff, Oberforster,
Strasburg, Germany, I learned that a
certain -beetle, Clerus formicarius, L.,
was a great destroyer of Scolytids in
the forests there, and from my know-
ledge of the habits of the nearly related
species, Thanasimus dubius, Fab., I felt
that it would be a most desirable species
to introduce into our forests to feed
upon the ‘ Destructive Pine-Bark Beetle,
and possibly check its ravages. There-
fore, the experiment of introducing this
beneficial Kuropean species into our
State for this purpose was recommended
to our Station officials and to owners of
the threatened Spruce and White Pine
444
‘[May, 1909.
forests. The proposed experiment was
at once approved, and the Station, aided
by liberal contributions from four of the
principal lumber companies, sent me to
Europe in quest of such insects as, in
my judgment would, when introduced
into our forests, accomplish the desired
end. I, therefore, proceeded at once
to Germany, and after visiting some
of the principal Pine and Spruce forests
of Alsace-Lorraine and Saxony, in Ger-
many ; Schyz, Lucerne and the Oberland
Bernese Alps in Switzerland, I started
back to America with over one thousand
live specimens of Clerus formicarius,
which was found to be especially des-
tructive to various bark beetles in all
of the forests visited. After my return
here, I found that the European species
wouid readily attack and devour the
Destructive Pine-bark Beetle, as well as
other bark beetles nearly related to it.
From what I have observed and learned
of this European bark-beetle destroyer, I
am confident that under proper manage-
ment it will check the ravages of the
destructive pine-bark beetle, and that
this enemy of Scolytids will, in time,
prove a valued protector of the pine and
spruce forests of this country.”
3. In another article by the same
author, (‘Insect Life,’ Vol. VI., p. 126),
is noted the reason for the selection of
this particular insect :—‘“‘ Out of quite a
number of enemies of Scolytids observ-
ed and considered, only one, Clerus
formicarius, was selected, primarily on-
account of its being regarded as the
greatest destroyer of Huropean bark
beetles; secondly, on account of the
general opinion of entomologists and
forest officials whom I consulted, and my
own convictions from a personal study
of its habits, that it would not be inju-
rious.”, . . ‘‘ Theimported Clerid does not
confine itself to one or two species of
bark beetles in one kind of trees, but
the adults, it would seem, will attack
and devour the adults of any species
of bark and timber beetles found in
the United States, and their larvz will
feed on the egg, larvee, pups, and
young beetles of any species infesting
the bark of pine and spruce trees.”
It appears that, within a few months
of the liberation of these insects, there
was a most remarkable diminution in
the damage to pine forests in America,
Many people, not unnatuarally, jumped
to the conclusion that this disappearance
of the pest was due to the activity of
the imported Clerus. But this was one |
of those coincidences that so often
lead to mistaken deductions. Referring
to this particular incident, the late Prof.
Riley remarks (‘Insect Life,’ Vol. VL,
_ ‘
ie
. 140) —Throughout Virginia and
West Virginia, where the spruce pines
have for some years suffered so severely
from the destructive work of Dendroc-
tonus frontalis, not a_ single living
specimen of the beetle has been found
during the present year. The clearest
explanation of this sudden change is
that the species was practically killed
out by the exceptionally severe cold of
last winter, since such was the case
with several other insects. Now, follow-
ing so closely on the introduction by
Mr. Hopkins of Clerus formicarius, how
easy it would have been to attribute
the sudden decrease to the work of the
introduced Clerus had not the decrease
been so general and extensive as abso-
lutely to preclude any such possibility.”
Such coincidences emphasise the care
that is necessary in the scrutiny of
apparently successful results.
I have been unable to find any later
references to this experiment. Nor do
I know whether it was finally crowned
with success or not.
Clerus formicarius is itself a beetle
of predatory habits. In its adult stage
it preys upon other beetles smaller and
weaker than itself. Itshould be noted
that it is (compared with the minute
size of the ‘ shot-hole borer’) a compara-
tively large insect, and is consequently
unable to penetrate the galleries of the
borer. It laysits eggsin the entrance
of the tunnels and its larve follow up
and devour those of the borers.
The family Cleride is already re-
presented in Ceylon, but none of our
' local species appear to have concerned
themselves with the destruction of
Xyleborus fornicatus, It is probable
that, being themselves indigenous to
the country, they have accustomed
themselves to prey upon other indi-
genousinsects. It is most probable that
the ‘shot-hole borer’ of our tea is an
accidental introduction of compara-
tively recent date.
MISCELLANEA: CHIEFLY
PATHOLOGICAL,
In view of the statement that Loran-
thus is attacking acacia trees in up-
country districts, it is of interest to note
that, in a study of the life-history of an
Australian species, Loranthus exocarpi,
the host plants in the neighbourhood of
Myrniong, Victoria, comprised Acacia
decurrens, Acacia dealbata, Acacia mela-
noxylon, three other acacias, Cherry,
Plum, two species of Casuarina, and
445
Plant Sanitation,
five other plants. Evidently Acacia is
particularly liable to be attacked by
this parasite, though the _ relative
frequency of the trees named in the
district is not stated. There are
twenty-five species of Loranthaceew in
Ceylon, six of which are restricted to
the moist low-country, three to the dry
region, and seven to the montane zone ;
the remainder are more generally, but
capriciously, distributed. Six are said
to be very rare, three rare, and four
rather rare. A list of the host plants
of the Loranthacee of Ceylon has
never been compiled; Trimen mentions
Rhododendron, coffee, Satvadora, Sym-
plocos, Hurya as hosts of various
species. The compilation of such a list
would provide interesting work for a
local botanist, and might subsequently
lead to valuable information with regard
to the conditions which render some
trees particularly lable to be attacked
by these parasites, while others in the
same neighbourhood are immune. Cacao
is attacked at Peradeniya, and a good
example may be seen near the well out-
side the station; mango trees especially
suffer; and the branches of the clove
are killed back by it. Camphor is
attacked at Hakgala. It may be noted
that specimens should be collected in
flower and fruit, with examples of the
host plant in the same state, if possible,
in order to ensure accurate determina-
ions.
In a recent case of tea root disease,
Rosellinia spread from the tea to the
dadaps and killed them out. This need
not be taken as a sign that dadaps
should not be planted, for Hosellinia
does not originate either on tea or
dadaps, according to our present in-
formation. Indeed, it is only what
might be expected, since the true
Rosellinia radiciperda, Mass., which was
discovered in New Zealand on fruit trees,
killed out grass and any other plants
which happened to come in its way.
In the same way, the chief Ceylon
Rosellinia—which is Rosellinia bothrina,
Berk., and Broome, not Rosellinia radici-
perda, which has not been found in
Ceylon—spreads from tea to Panazx,
and kills the latter with astonishing
rapidity ; but it leaves untouched any
cacao or Hevea which happen to stand
in its path. Such selective parasitism
is not uncommon, though it is not such
a universal rule as a study of the
Uredinece (i.e., Henvileia) would lead us
to expect. Homes semitostus attacks
Jak and Hevea—both, it may be noted,
laticiferous trees, though it is improbable
that that is the controlling factor—but

though these are growing in the midst
of dead jak roots covered with the
fungus.
Ustulina zonata, Lev., the common
tea root fungus of the low-country and
up to an elevation of 3,000 feet, has been
found to originate on Albizzia stumps
and tospread from them to the tea.
It was already known that Grevillea
stumps furnished it with a jumping-off
ground in practically all instances of its
occurrence, but now Albizzia stumps, in
accordance with expectation, must be
added. This is a spore-borne disease,
and when I was developing Ustulina on
teastumps in pots under bell glasses on
the laboratory verandah, I had great
difficulty in preventing its growth on
other dead tea stumps or coconut tissue,
also under bell glasses. In contradistiuc-
tion to many of our disease fungi, the
spores apparently germinate readily,
and this fact should enable us to obtain
further information about this parasite
rather more easily than is usually the
case, when time permits, On estates
the spores are blown about and lodge
on the cut surfaces of the Grevillea
stumps; there they develop and grow
downwards, destroying thestump and
passing from the Grevillea roots to any
tea roots which may be in contact with
them. Meanwhile the fructification is
formed on the Grevillea stump in black
encrusting plates, and the spores which
exude from the spore-chambers are
ready to carry the disease elsewhere. It
isnot often that the fructification is
formed on the tea bush, because the
bush dies and is uprooted before the
mycelium has ascended in the stem to
the ground level. Ustulina zonata was
first found on coconut, but probably
only saprophytic. It causes root disease
in the Pumelo, and in an unnamed tree
in the Peradeniya Gardens. Many
European mycologists consider that it is
identical with Ustulina vulgaris, which
is common in Europe but not parasitic ;
but in its typical form it seems suffi-
ciently distinct.
In connection with the above, one
wonders who is going to he the first to
introduce the Trewhella screw jak for
uprooting trees. When some of the
felled grevilleas do not exceed six inches
in diameter, it would be quite as easy to
uproot them with this instrument as to
fell them and leave the stump as a
starting point for Ustulina, Of course
446
it isa question whether the outlay and
the possible extra cost of working for
each Grevillea exceed the value of (on
the average) six tea bushes and the cost
of liming and trenching. There is, too,
always the possibility that the Grevillea
stump will be rotted by other, harmless,
fungi, and possibly the sporting tenden-
cies of the Ceylon planter influence him
in accepting what is practically an even
chance. I notice that the makers of this
instrument have gone so far as to put an
illustrated advertisement in the ‘‘ Indian
Planters’ Chronicle”; possibly Ceylon’s
turn will come some day.
The catch phrase, ‘‘the bark is the
mother of rubber,” is again being pressed
into service. This is somewhat unfor-
tunate, since it leads to the same train
of erroneous ideas which gained curreucy
some years ago, and causes supporters
of various tapping systems to imagine
advantages which are certainly non-
existent. It would be more correct,
though open to scientific objections, to
say that the cambium is the mother of
rubber, just as it is of wood and bark,
Some time ago, Betel plants were
imported from India by the Agricultural
Society. Some of these, plantedin the
Stock Garden, soon became diseased, and
were forwarded to Peradeniya for
examination. As they were rooted
cuttings, carefully packed, and in the
early stages of disease, it was possible to
form a more accurate opinion of the
cause than is the case from the bundle
of half-rotten stems which is usually
sent. The leaves were covered with
blackish-brown, o1 almost black, angular
spots, with a broad yellow margin and -
an outer greenish yellow zone. Some of
these. spots were three centimetres in
diameter. The upper surface of the
spots was dry, but the lower surface was
viscid, being covered with a gummy
substance containing innumerable bac-
teria, A cross section through the leaf
revealed the same bacteria within the -
tissues, but no fungus hyphae. It is
most probable, therefore, that the
disease of the Betel which attacks the
leaves and stem is due to bacteria,
though of course there may be more
than one such disease. Pressure of
other work has prevented any further
investigation; the subject is (unfortun-
ately!) not forgotten, but remains
in that ever-expanding limbo entitled
‘‘agenda,”

MISCELLANEOUS PESTS.
“THE RAT PROBLEM.”
Tuese are, no doubt, many people, both
in the scientific and commercial worlds,
who are at present quite unaware that
rats are in any way connected with a
problem. Mr. Boelter, however, is con-
vineed about the matter, and in the
book now before us has taken up the
case for prosecution of the rat in such
a way that all those who read this
book will be bound to pass a verdict
very derogatory to the rat, in spite of
what may be said by those who argue
that every animal has his useful part
to play.
The first chapter is devoted to the
natural history of rats. The brown rat,
which has nearly replaced the old black
rat, was probably introduced into
England in 17382, and now it is quite safe
to say that we have over 40,000,000 in
our islands. A diagram illustrates ina
very clear way how the brown rat has
gradually established itself in most parts
of the world. Man has been the means
by which they have emigrated, and in
this direction it may be remarked that
civilisation has done a great deal to
upset the balance of Nature and to
establish many plagues and diseases.
The illustrations are old and familiar,
end it is probable that photos would
have been better nowadays. Consider-
ing the way in which vernacular names
may mislead people who are not acquaint-
ed with the habits of our wild animals, we
should have liked to have seen a little
more written about the water-rat. This
animal does not belong to genus ‘‘ Mus”
(true rats), but to genus ‘ Arvicola”
(voles), and itis to behoped that the
commercial loss caused by the ravages
of the brown rat will not be heaped on
to the back of the water-vole.
The second chapter is devoted to the
loss caused by rats, andthe leyendary
Pied Piper of Hamelin is mentioned. A
circular has been issued by the Incor-
porated Society for the Destruction of
Vermin, and the replies given to various
questions by farmers, poultry farmers,
gamekeepers, drapers, grocers, hotel
proprietors, warehousemen and_horse-
owners ai'e most convincing. The above
Society, with Sir James Crichton Browne
as its president, hope to bing into
operation a rat law similar to that
formed by Zuschlag and his society in
Denmark. The annual loss caused by
rats is estimated at £15.000,000, and
besides that they are the means of
spreading trichinosis and the plague.
The fourth chapter is devoted to the
means of the extermination of rats.
The part played by the owl, weasel and
kestrel as natural enemies of the rat are
described. Itis, of course, a great pity
that these useful animals are so_perse-
cuted for things which they very rarely
do. A very interesting biological law is
brought out in this chapter by the
story of an old ship’s mate who used to
catch a dozen or so rats on his ship and
then kill all the dozen and give them to
the bucks to eat. These were then
released. By this means he used to
keep his rats at a minimum, and the
process had to be repeated in about six
months, For the welfare of most
mammals it is necessary that the temale
population should be in excess of the
male, If, however, the conditions are
reversed, then -breeding females and
their litters are upset, and if this process
were continued long enough the species
may be exterminated, This has been
applied to some districts in Australia
with regard to rabbits and found to be
a great success.
The various mechanical means of
catching rats is considered, and the Old
Royal Rat Catchers’ works are quoted.
Under man’s care the cat has given up
the chance of being bitten for a more
homely saucer of milk. Phosphorus,
strychnine, arsenic, sulphate of calcium,
and one or two other bases of the
common rat poisons are reviewed ina
most satisfactory manner,
Of the bacterial preparations it is
interesting to note that the bacillus
discovered by Newmann in the urine of
a two-year-old child appears to be the
most efficacious. Itis the active prin-
cipal in Ratin. Danysz’ preparation
and the Liverpool virus are not spoken
of so favourably. It has to be re-
membered, however, that Xylander,
whose works are very reliable, consi-
dered microbic rat poisons at present
(1908) as being far from safe and reliable.
Chapter V. contains a few of the more
important conclusions arrived atin the
first four chapters, and the chief rea-
sons given to account for the prevalence
of the rat are as follows: (a) Its physical
and mental faculties, (b) its great fecun-
dity, (c) the increase of human popu.
lation, (d) the killing of the rats’ natura]
enemies, and (¢) the total absence of
co-operation in the methods chosen by

man to exterminate therat. Itisthis cultural Societies would do well to de-
latter reason that will be the most im-
portant factor to be overcome when the
time comes to commence a campaign
against the rat. The last chapter con-
tains the Bill already referred to, the
whcle expenditure of which would fall
on the Local Authority.
The book is well written and mistakes
are few. All those interested in the
subject should read it, and our Agri-
vote a little time to the subject. The
rat should certainly be exterminated,
but we fear conservative Englishmen
will not move very quickly in the
matter.

OSTEOPOROSIS.
THe MINERAL CONSTITUENTS OF Foops.
By HERBERT INGLE, B.SC.,
F.R.S.S.A., F,C.S.,
Late Chief Chemist, Transvaal Depart-
ment of Agriculture.
F.1.C.,
The importance of a ‘ well-balanced ”
ration in feeding animals has long been
recognised, and most intelligent stock-
keepers pay some attention to the
albuminoid ratio of the foods they use.
That the requirements of animals
with respect to the proportions of albu-
minoids or ‘‘ flesh-formers” tofats and
carbohydrates or “‘ heat-formers” in their
diet vary with circumstances is also
realised by many, and proper attention
is paid to this in framing rations for
various animals kept under different
conditions. But beyond the _ general
and vague belief that the food should
contain a sufficient amount of “ash
constituents ” or ‘‘ bone-formers,”’ little
consideration has been given to the diet
of animals with respect to its mineral
constituents.
The author has recently been investi-
gating from a chemical aspect a disease
of the bones of horses, donkeys, and
mules, which is particularly prevalent
in South Africa, and from a consider-
ation of the results obtained has been
led to atheory which, he ventures to
think, may account for the prevalence
of the disease in that country, ard
may indicate means for its prevention,
or at least amelioration, and at the
same time furnish points worthy of
consideration by all interested in the
feeding of animals.
The disease in question, Osteoporosis,
is characterised by an extraordinary
weakening of the bones, and is the
cause of considerable losses among
stable-fed horses and mules,
In 1905, the writer examined the
bones of a considerable number of horses,
mules and donkeys. The bones were
merely numbered, and he was_ not
informed which were from diseased and
which from healthy animals. When
the analyses were finished he found it
possible to accurately divide the bones,
from their chemical composition, into
those from healthy and those from
diseased animals.
Those from diseased animals were
much richer in organic matter and
poorer in ash than those from healthy
animals. The most conspicuous differ-
ence was shown by taking the ratio
of nitrogen (which is a measure of the
nitrogenous substance—ossein—present)
to ash in the bones, as the influence of
the very variable fat present was thus
eliminated.
The value of this ratio was found to
vary in the case of diseased animals
from 1: 9'8 to 1: 11'7, the mean value
being 1: 10°8; with the healthy animals
the ratio varied from 1: 13°5 to 1:
15°6, the means being 1: 14°37.
In the bones of healthy animals the
mean amounts of lime and phosphorus
pentoxide were 32°28 % and 21:41 %
respectively, while with the diseased
bones the figures were 28°50 and 19:06 %.
In tabulating the results and consider-
ing the possible causes which might
tend to produce such a condition of the
bones, the author was led to the con-
clusion that the peculiar diet of work-
ing animals in the country—a ration
composed wholly of cereals, either oat-
hay or oat-hay and “ mealies” (7.e., maize
or Indian corn)—might possibly account
for the frequency of the disease in
South Africa.
Some veterinary surgeons ascribe the
prevalence of the disense to deficiencies
of the food-stuffs ii iime and phos-
phoric acid, while others are persuaded
been ter? eee Ct ahd ee tae
May, 1909.|
that the disease is caused by a_ specific
micro-organism and is of an epidemic
character, though no organism has been
found, nor can the disease be trans-
mitted by inoculation or administration
of diseased bone.
Now the proper ratio of phosphorus
pentoxide to lime in the food of
animals in order to favour bone forma-
tion and renewal, has not been directly
determined, but may be deduced from
one or two considerations. Thus, the
milk of animals may be assumed to
contain these ingredients in proper pro-
portion for the needs of young animals.
Cows’ milk contains on the average
about 0°17 per cent. of phosphorus pen-
toxide and 0°15 per cent. of lime, ze.,
in the ratio of 100 phosphorus pentoxide
to 89 of lime. In the bones of animals
the two substances are present in the
ratio of about 100 of phosphorus pen-
toxide to 150 of lime.
According to Rothamstead experi-
ments, the amounts of the two substances
present in 1,000 lbs. of the whole bodies
of animals are as follows :—
Phosphorus
pentoxide. Lime. Ratio.
Fat calf so 1d330 16°46 100 108
Half fat ox ... 18°39 21'11 100 116
Fat lamb _... 11°26 12°81 100 114
Store sheep... 11°88 13°21 100 112
Store pig... 10°06 10-79 100 107
Fat pig 6°54 . 6°36 100 95
Remembering that some of the phos-
phoric acid of the ash is present in the
food in the form of organic matter and
is utilised in the animal in the formation
of tissue other than bone (e.g., brain) and
to a greater extent than lime, it may
probably be assumed that the food of
an animal should contain about equal
parts of phosphorus pentoxide and lime
in its ash.
In the two substances which form the
staple diet of horses and mules in
S. Africa—oat-hay and mealies, lime and
phosphorus pentoxide are present in the
ash in the following proportions :—
Phosphorus
pentoxide. Lime.
Oat-hay . 100 77
Mealies (maize grain) 100 4.
These are calculated from the ash
analyses of Wolff. In South African
grown oat-hay, I find that both the
lime and phosphorus pentoxide present
are smaller than in the average of
Kuropean samples, and that on the
average the ratio is 100: 51.
_ From the figures given by Warington
for the lime and phosphorus pentoxide
57
449
Live Stock.
in the whole of the oat-erop, the ratio is
100: 60.
It is evident from the above figures
that the usual South African diet for
working animals does not supply lime
and phosphorus pentoxide in the propor-
tions which we have adduced reasons
for believing are best adapted for the
nutrition of bone. On the contrary a
ration consisting of oat-hay and mealies
provides a large excess of phosphorus
pentoxide over lime,
As to the injurious effect of the pro-
longed use of such a diet upon horses
and mules, we have no records of direct
experiments having been made, but in
1891, Weiske experimented with rabbits
on these lines,
Adult rabbits, from the same litter,
were divided into four lots and fed
for three months upon:
1. Hay.
2, Mixture of hay and oats.
3. Oats alone.
4. Oats to which sodium dihydrogen
phosphate was added (so as to increase
artificially the ratio of phosphoric acid
to lime in the food). y
It was noticed that the urine of rabbits
of lots 1 and 2 was alkaline, while that
of lots 8and 4 was strongly acid. At
the end of the period the rabbits were
killed, weighed, and their skeletons
cleaned and weighed.
The results were as follows, the
weights being grammes,
Lots 1, 25 By 4,
Weight of bodies . 2,430 3,420 2,030 1,810
Weight of skeletons ... 87°66 115'80 69°28 63.76
The bones of lots 1 and 2 were heavier,
stronger and richer in ash than those of
lots 3 and 4. Those of lot 4 were very
thin and breakable and contained a
smaller poroportion of lime and phos-
phorie acid than the others.
In a later paper (1894), Weiske records
experiments in which the effects upon
the bones of animals feeding upon oats
alone were successfully neutralised by
pee oalibion of carbonate of lime to the
iet.
Another point of importance may be
here pointed out—the erroneous idea that
bran, which is almost universally re-
garded as being particularly rich in
*‘ bone-forming material,” 7.e. ash, is use-
ful in adding bone formation. From
the point of view now under consider-
ation, bran would be a particularly bad
food, as the ratio of lime to phosphorus
pentoxide is extremely low—the actual
proportions present being approximate-
ly 0:3 per cent. of lime to 3°3 per cent,
Live Stock.
‘of phosphorus pentoxide, or in the ratio
of 9: 100. This is confirmed by the
occurrence of a bone disease, known as
“bran. rachitis,” ‘‘bran disease” or
‘“‘miller’s horse rickets” which is observed
in animals fed largely on a bran diet.
It is thus evident that, whether osteo-
porosis be due to a specific organism
or not, a condition of the bones of ani-
mals similar to that which results from
the disease may be induced by the

There can be little doubt that animals
may be gradually accustomed to live
upon adiet thatis at first unsuited to
their requirements, and I have every
reason to believe that the South African
bred horse is less liable to succumb to
osteoporosis, or to suffer from deficien-
cies in the composition of the ash of his
food, than are imported animals.
Interesting accounts of outbreaks of
osteoporosis among imported. horses,
donkeys. and mules in 1898 and in 1904
at the Military camps of Wynberg and
Middleburg in Cape Colony are given
by Capt. Lane, who particularly noticed
the improvement effected in the diseased
animals by a change in diet from oat-
hay, mealies and bran to one containing
lucerne, green forage and bone meal.
These cases afford strong confirmation
of the success of the treatment which
the theory here adduced would indicate
as beneficial, though the treatment was
adopted rather with the object of
increasing the amount of both’ phos-
phorie acid and lime in the food, than
of increasing the ratio of the latter to
the former (which indeed was, in my
opinion, the cause of its success).
It will be seen from the above con-
siderations that the writer is of opinion
that it is not the poverty of South
African grown produce in lime and
phosphoric acid (as compared with
European grown food-stuffs of the same
kind) which is to be blamed for the
prevalance of bone troubles among
animals there, but rather the practice
of feeding such animals exclusively
upon a cereal diet. :
Probably in Europe, if horses and
mules were fed entirely upon oat-hay,
diseases would result, though
there is some evidence that in certain
districts in Africa, both the soil and
the crops grown on it are poorer in
lime than the corresponding crops
grown elsewhere. Our analysis of.
Transvaal soils indicate that they are,
May, 1909.]
as compared with English soils, very
poor in phosphoric acid, nitrogen and
lime, but usually rich in potash.
Now to plants, phosphoric acid is
apparently more important than lime,
at least so far asseed formation is con-
cerned, and the yield of seed is often
jimited by the amount of phosphoric
acid available.
In many parts of South Africa it
has been the practice to attempt to
compensate for the assumed deficiency
in lime and phosphates of the usual
food-stuffs given to. animals, by the
administration of bone meal, and
‘*sterilised bone meal” is largely used
for the purpose. Such a practice un-
doubtedly tends to mitigate the evil
alluded to, for we may take it that
bone meal contains lime and phosphoric
acid in approximately the correct pro-
portion for bone nutrition.
But to adda material containing the
two substances in correct ratio, to a
food which otherwise is far too rich
in phosphoric acid, though it improves
the final ratio in the mixture,-is not so
satisfactory a method as the substi-
tution for a portion of the oat-hay
of a food-stuff relatively rich in lime,
e.g.,a leguminous fodder-crop like lucerne
or cow-peas. Moreover, the mere ex-
tended use of leguminous foods would
improve the rations of animals in other
ways, notably by narrowing the albu-
minoid ratio.
In conclusion, I would urge the im-
portance of giving due consideration,
in framing rations for animals, to the
amount and composition of the ash of
the foods, for the supply of materials
for the pruper development of bone,
and of the mineral constituents neces-
sary for vital processes are of as much
importance to the well-being of the
animals as that of proteids, carbo-
hydrates and fats in appropriate quan-
tities. Where a considerable variety of
food-stuffs is employed, e.g., in Hngland,
the probability of much injury being
done by ignoring this aspect of the
question is not nearly so great as when
two or three constituents only enter
into the ration, but even in such cases
a proper recognition of the points I
have raised in this paper would pro-
bably often be useful.
The writer is fully convinced that if
due regard were paid to those points
and a more varied diet were supplied
to horses and mules in South Africa,
there would be a marked improvement
in the health and well-being of the
draught animals, and that in time

horses of greater weight of bone would
piobably be reared.
Possibly the same arguments may
apply to cattle, but asarule the ox is
allowed to graze and thus obtain greater
variety of diet, so that its needs in
this connection are probably not so
great as with stall-fed animals.—Jour-

IN-BREEDING,.
In-breeding is recommended by many
writers, and especially for show pur-
poses. The theory has been advanced
that the wild birds in-breed, and yet
they are healthy. In many instances
this is right, but it must be remembered
these birds only lay in the spring and
summer, according to their nature.
Poultry people keep their birds to lay
eggs during the autumn and winter
months, which is quite a different
matter. If we domesticate our fowls for
our convenience, then we must breed and
treat them accordingly. If we are going
to breed for show, then it is wise to doa
little in-breeding, but not tothe extent
that is reeommended ; if so, their consti-
tutions are undermined.
We have experimented with in-breed-
ing in every variety, and some stand it
much better than others. Take, for
instance, a man who in-breeds his
poultry for show purposes. Say, he
breeds seventy fowls; he picks out just
the strongest of the young ones, not
more than fifteen or twenty, to breed
from in his own yard, and more often
not half that number. >
It is a frequent thing to hear breeders
say of pure birds, talking of others’
stock, and we hear the remark especially -
at shows, ‘“‘ Yes, that exhibitor has some
real good birds; but he in-breeds too
much.” The answer to that is usually,
‘*How do you know that?” The reply
is, ‘‘ We once bought a stock bird or birds
from him, and they soon died, as they
had no stamina.”
There are hundreds who do the same,
We once knew a poultry-keeper who
bought all his stock birds from people
who win at most of our shows—that is,
the small birds, which are usually called
the ‘‘culls.” These were all bought
cheap, and what was the result? Out of
very nearly 500 pullets, upwards of 100
wasted away, and the others did not
average sixty eggs each during the year,
The poultry-keeper came to grief, and
the money was lost.
Live Stock. 452 [May, 190%
If eggs or good table birds are show who do not get eggs in winter, and
required—that is, good strong table
birds—the stock must not be iu-bred; if
so, the birds do not fulfil their mission,
Those who write articles Gn in-breeding
do a great deal more harm to the utility
poultry-breeders, as they write that
they can in-breed and yet do well. In
one way it pleases them, because they
need not yet buy fresh male birds, but it
is misleading to those who do not know
any better.
We will take our readers back to the
farmers of twenty years ago, when the
whole village would not have fresh
blood for years. The system was for
farmers’ wives to exchange male birds
about every two or three years with
each other.
What.was the result? In many cases
they did not breed achicken until the
end of spring, and not many of them
before the middle of summer. The
simple reason was they could nut get a
hen to sit before that time.
We can well remember the time when
farmers did not have a single egg for
three or four months during the autumn
and winter. (1) Because they in-bred.
(2) They bred from mongrel cocks. (8)
They made no selection of their stock,
partly because they fed them on the
very poorest of grain, such that the’
millers would not grind for their pigs.
Fortunately, these last few years
farmers have treated their fowls dif-
ferently. What brought them to do so?
Bad times, and the purchase of fresh
blood; they gave the birds better food,
and what has been the outcome of it all ?
They have made better prices for their
poultry and eggs, and find there is
nothing pays better on the farm than
poultry.
Geneial in-breeding with ordinary
stock kept for utilitarian purposes is a
step backwards, and it means loss and
disappointment.
It must be remembered there are
poultry-fanciers who keep birds for
in many cases they keepa number of
mixed birds of all kinds to lay eggs for
their own consumption. But when
people keep prize birds of the up-to-date
utility breeds, they lay eggs all the
autumn and winter.
This is one reason why the Oprington
varieties have spread so marvellously
fast as show birds.
We always recommend our readers to
take up the newer breeds because of
fresh blood having been used, and the
introduction of this always means added
inactivity to the egg organs. :
When they complain that new varie-
ties are rot good layers, itis the fault
of those who have handled them.
There is no specific way to make hens
lay. Many things will tend to increase
the number of eggs laid. Volumes have
been written upon the subject, and each
writer lays special stress upon his or her
remedy. We cannot go into detail, but
will give a list of the help recommended,
and our readers can try the ones they
think most applicable to their own
case :—
1, Certain birds lay more eggs than
others.
2. Young hens lay better than older
ones.

laying capacity more highly deve-
loped than others.

BEE KEEPING.
BEES DO NOT INJURE SOUND
FRUIT.
AN INTERESTING EXHIBIT AT A FAIR,
CONSISTING OF RIPE FRUIT IN A
GLASS HIVE CONTAINING BEEs.
By JOEL GILFILLAN.
At the Grangers’ Fair, held this year
in Wilmington, Del., I had charge again
of the Bee Department. Besides the ex-
hibit of honey (comb and extracted) and
wax, I had a series of observatory hives
exhibiting the various conditions and
workings of the bees from the time a
swarm was first hived until the harvest
of honey was taken off. These were
similar to the ones of thé preceding year,
the illustrations of which were published
in the November Ist issue, 1907. There
was one hive of a different character,
which created something of a sensation.
This one is shown by the accompanying
engraving. lt was a three-story glass
hive, the upper story containing ripe
fruit, a bunch of grapes, a pear, and a
each. At the time the picture was taken
it was a little cold, and the bees were
clustering on the combs; but nearly all
- make honey from fruit.”
the time during the four days of the
Fair the bees were freely moving about
among and over the fruit. There was
acard on the hive, upon which was
written, ‘‘Bees do not injure sound
fruit.” On the second day of the Fair
one of the grapes on the bunch burst
open, and the bees set to work and soon
cleaned it up, and that empty grape
skin hung there among the sound grapes
during the remaining days of the Fair,
speaking louder than any voice. Men
would stop before this exhibit and
ponder a long time and then turn away
with the remark, ‘‘ Well, that settles the
question.” Sometimes a tew would rush
past without taking time to read the
card, and say as they passed, ‘‘ There,
that shows how the bees get honey from
fruit.’ One very wise felllow, who was
leading a company around, and who
was quick to read the cards on the
hives, and who tried to.be very wise,
began describing this one before he
reached it, saying, ‘‘Now here we have
a clear demonstration of how the bees
By this time
he had read the card, and he merely
said, ‘‘Oh!” and concluded it was time
to pass on to other departments of the

SCIENTIFIC AGRICULTURE.
INOCULATION OF LEGUMINOUS
CROPS.
In view of the fact that the cultivation
of leguminous crops under suitable con-
ditious offers a means of enriching the
soil with nitrogen, and that this power
of assimilating atmospheric nitrogen is
due to the presence and action of nodule-
forming bacteria on the roots of these
plants, it would seem, at first sight, a
comparatively easy matter to ensure
the presence of the bacteria, and the
consequent production of crops of
greater value, by inoculating the soil
with the organisms in question. A con-
siderable amount of experimental work
on this subject has been carried out in
the United States, in Germany, Canada,
and—quite recently—in England, but
the results attained, speaking generally,
have not, so far, been by any means of
so promising a nature as was at one time
anticipated. Some trials, it may be men-
tioned, too, have lately beer made at
Antigua and Grenada, under the direc-
tion of this Department, and it is hoped
shortly to publish a note on the results
“Cultures of bacteria for inoculation,
purposes have at different times been
prepared and sent out in a number of
different forms, one of the latest being
that known as‘ Nitro-Bacterine,’ devised
by Professor Bottomley of King’s College,
London. Experiments with this mate-
rial were carried out by the Royal
Horticultural Society at the Wisley
Gardens, England, during the summer
of 1908, the soil of these Gardens being
of the kind where inocwation might be
expected to have a good effect. An ex-
haustive report on this experimental
work is contributed by Mr. F, J. Chit-
tenden, F.L.S., to the Journal of the
Society for November last (Volume
XXXIV, Part I), from which it appears
that from no point of view did inocula-
tion prove to have a beneficial effect.”
_ The following summary of the results
is given at the end of Mr. Chittenden’s
report :—
Scientific Agriculture.
‘A trial of the effect of inoculation of
peas with ‘Nitro-Bacterine’ was con-
ducted at Wisley in 1908.
The soil of the Wisley Gardens is one
more likely to respond to such inocula-
tion than the majority of garden soils.
The experimental area was divided
into twenty-four equal plots, twelve
being on well-worked soil, and twelve
on soil that had been fallowed in 1907.
Each pair of plots on the cultivated
ground received different soil treatment,
and the corresponding pairs on the fal-
lowed land received the same treatment.
One of each pair of plots had seed
which had been inoculated sown upon it ;
the other, seed which had not been
inoculated. One row of each of four
varieties was sown upon each plot, the
same varieties being used throughout.
It is shown that the Wisley soil is
lacking in none of the chemical elements
necessary for the successful growth and
development of nodule-forming bacteria,
Seven out of the twelve plots on which
inoculated seed was sown, gave smaller
crops than the corresponding uninocu-
lated crops, and one gave an equal crop,
There was, under no soil treatment, a
consistent increase in the crop due to
inoculation.
The total weight of the crop from the
whole of the plots receiving inoculated
seed was 450 lb., while the total from the
plots in which uninoculated seed was
sown, was 515 lb. The uninoculated seed
therefore gave, in the aggregate, a
crop per cent. heavier than the inocu-
ated.
The crop from the inoculated seed was
not better inany way than that from
the uninoculated, nor did it reach matu-
tity earlier.
There was a remarkable difference in
the yield from the well-cultivated land
and the fallowed land, greatly in favour
of the former.
It is concluded that the inoculation of
leguminous crops with ‘ Nitro-Bacterine’
in ordinary garden soils is not likely to
prove beneficial.’"—Agricultural News

THE CONSERVATION OF SOIL
MOISTURE AND ECONOMY IN
THE USE OF IRRIGATION
WATER. —
By KE. W. HiLGARD AND R. H.
LOUGHRIDGE.
The exceptionally dry season of 1897-8,
coupled with the early cessation of rains
in the spring of 1897, have brought
about in California a more extended
failure of cereals and pasturage, and
shallow-rooted crops generally, than in
any year since the State became a
prominently agricultural one, the season
of 1876-7 being the nearest to carry
with it a similar deficiency in crop
production. It has been the effort of
the Experiment Station to utilize the
present unusual season for the study
of the limits of endurance of drought
on the part of the several crop plants,
and with it to determine the minimum
of water that will suffice for their satis-
factory growth in the several soils.
While far from completed, this work
(involving many hundreds of. determin-
ations of moisture in soils) has already
yielded some results which render it
desirable that they should be placed
before the farmers and discussed at
once, in order to provide against a
recurrence of avoidable injury in the
future.
Amount of water required by Crops.—
lt is notvery generally understood how
large amount of water is required for
the production even of fair crops; for
the maximum of possible product is
rarely obtained on the large scale,
because it is not often that all conditions
are at their best atany onetime and
locality. But from numerous observ-
ations, made both in Kurope and in the
Eastern United States, it has been
found that from 300 to over 500 tons
of water are on the average required
to produce one ton of dry vegetable
matter. In Wisconsin, King found
that a two-ton crop of oat-hay re-
quired over one thousand tons of
water per acre, equal to about nine
inches of rainfall. The average rate
tor field crops at large is given by
European observers at 3825 times the
weighs of dry matter produced, being
at the rate of about three inches of
rainfall actually evaporated through
the plant, :
These data should enable us to
estimate the adequacy of the moisture
contained in the soil at the beginning
of the dry season to mature the crop,
provided «we make due allowance for
Hie 7.

any growth already made at the time,
and provided also that the estimates
as to the water-requirements derived
from the experience of the countries
of summer rains (the humid regions)
hold good for the arid region also.
Wicther or not this can be assumed,
is among the points our experiments
are designed to determine. The sur-
prisingly successful growth and bearing
especially of deciduous trees, without
irrigation, despite a drought of five or
six months in the ‘‘ Franciscan climate,”*
has led to an impression that a_ less
amount of water may suffice under
arid conditions. For in the Kast, as
many weeks of drought and _ intense
heat would frequently suffice to destroy
the crop.
Probable causes of this endurance of
drought.—Doubtless the main cause of
this remarkable endurance is to be
found in the much deeper rooting of all
plants in arid climates; whereby not
only a much larger bulk of moist soil is
at their command, but the roots are
withdrawn from the injurious effects
of hot, dry surface and air.
This deeper range of the roots is not
the result of foresight on the part of the
plant. It could not occur on KEKastern
soils, because of the intervention, in
the great majority of cases, of difficultly
penetrable subsoils; from which, more-
over, plants could draw _ but little
nourishment on account of their ‘ raw-
ness.” Inthe arid region, as a rule,
subsoils in the Hastern sense do not
exist; the soil mass is practically the
same for several feet, and in the _ pre-
valent soils is very readily penetrable to
great depths. This, summanily speak-
ing, isdue tothe slight formation of
clay, and the rarity of heavy rains in
the arid region. And this easy pene-
trability of the soils implies, moreover,
that being well aerated, thedepths of
the soil are not ‘‘ raw,” asinthe Hast ;
and therefore that the ‘‘subsoil ” such
as itis, may fearlessly be turned up as
deeply as the farmer is willing to go
with the plough, without danger of injur-
ing the next season’s crop, in all lands
that are well drained; as, by reason
of their depth and perviousness, is the
ease with most California soils.
The accompanying plate illustrates
from Nature the deep penetration of a
peach root developing in a normally

Powell to the climate of middle and southern Cali-
fornia, which is characterized by the concentra-
tion of rains within a winter which is mild enough

deep, well erated ‘bench” soil, in a
manner quite impossible to the same
root when growing in land underlaid,
as are most Hastern ones, by a subsoil
which either is too dense or too wet to
be penetrated and utilized by the tree.
A glance at the figures suffices to
show that, while a root system like
plate 1, a typical Eastern tree root will
stand in absolute need of frequent
rains or irrigation to sustain its vitality,
such a one as plate 2 may brave pro-
longed drought with impunity, being
independent of surface conditions, and
able to perform all its functions out of
reach of stress from lack of moisture.*
It is equally clear that it is to the
farmer's interest to favour, to the
utmost, this deep penetration of the
roots, both in the preparation and tillage
of the ground, and in the use of irri-
gation water. For if the latter is used
too frequently or too abundantly, the
salutary habit of deep rooting will be
abandoned by the plant, and it will,
as in the Kast, be dependent upon fre-
quent rain or irrigation ; and also, owing
to the small bulk of soil upon which
it can draw for its nourishment, upon
frequent and abundant fertilization.
Kastern immigrants as well as a large
proportion of California farmers do not
realize the privilege they possess of
having a triple and quadruple acreage
of arable soil under their feet, over and
above the area for which their deeds call ;
and they tenaciously continue to adhere
to precautions and practices which,
however salutary and necessary in the
region of summer rains, do not apply
to this climate. The shallow ploughing
so persistently practised results in the ~
formation of a ‘plowsole” that plays
the part of the Eastern subsoil in pre-
venting root penetration ; limiting their
range for moisture and plant food and
thus naturally causing crops to succumb
to a slight stress of season which ought
to have passed without injury, had the
natural conditions been taken into
proper consideration.
Roots follow moisture. -Very striking
examples of deep routing as the result
of vertical moisture penetration can be
observed in some of our native trees,
which, while naturally at home on moist
ground, are nevertheless sometimes
found forming luxurient clumps on the
slopes and even summits of our coast
ranges and foothills. If we examine
the ground where this occurs in the
case of California laurel, we will gener-

ally find that the soil in which they
grow is underlaid by slate or shale
standing on edge, into the crevices of
which the roots penetrate, wedging them
open; while themselves flattening out,
and thus penetrating to moisture at
considerable depths. The same may be
observed in the case of the erect ‘‘bed-
rock” or foothill slates of the Sierra,
on which native as well as fruit trees
flourish in very shallow soils, some-
times reaching. permanent moisture at
the depth of ten or more feet below
the surface. It can readily be observed
during rains that there is comparatively
little run-off from the surface of these
lancs underlaid by vertical shales.
On the same principle, the grape
vines which bear some of the choicest
raisins of Malaga on the arid coastward
slopes, are made to supply themselves
with moisture, without irrigation, by
opening around them large, funnel-
shaped pits, which remain open in winter
so as tocatch the rain, causing It to
penetrate downward along the tap-root
of the vine, inclay shale quite similar
to that of the California Coast ranges,
and like this latter, almost vertically
on edge. Yet on these same slopes

searcely any natural vegetation
finds a foothold. 3 Fas
Similarly the ‘‘ryots” of parts of India
water their crops by applying to each
plant immediately around the stem such
scanty measure of the precious fluid as
they, have taken from wells, often of
considerable depths, which form their
only source of water-supply. Perhaps
in imitation of these, an industrious
farmer has practised a similar system
on the high benches of Kern River, and
has successfully grown excellent fruit
{or years, on land that originally would
grow nothing but cactus. Sub-irri-
gation from pipes has been applied in
a similar manner.
_The principle flowing from the aboveis
simply that the most economical mode
of using irrigation water is to put it
“where it will do the most good,” close
to the stem of the plant or trunk of
the tree, and let it soak downward so as
to form a moist path for the roots to
fellow to the greatest possible depth.
It is this deep penetration to natural
moisture, as a matter of fact, which
enables the small quantities supplied to
produce such marked effects.

NOTES AND QUERIKS.
N.C. P.—The plant you refer to is
Typha augustifalia, a reed or rush some-
times (butincorrectly) called the bull-
rush, and also known variously as cat-
tail flag, reed mace, and elephant grass.
The Sinhalese name is Hambu-pan. The
leaves have some value for making hats,
mats, &ec., and the fluffy material found
in thespadix was at one timea good
dealused for stuffing. The plant has
been favourably reported onas a fibre
for paper-making. It isfound growing
in abandoned paddy fields, e.g., in the
neighbourhood of Anuradhapura.
Miscellaneous, 458
Kapoxk.—A leaflet on the subject is
just about to be issued. In it you will
find all the information you want. Do
not confuse this with the ordinary spin-
ning cottons which are all species of
Gossypium, some of which are, owing to
their size, called ‘“* Tree Cottons.” Kapok
is botanically Hriodendron anfrac-
tuosum, and has long been grown as a
fence plant. The name Kapok is said to
bea Malay word, probably introduced
by the Dutch.
A. O.—Tinospora cordifolia is the
Sinhalese Rasa-kinda (Tamil Seenthil).
Yes, itis used to someextent in Euro-
pean practice, and applications have
been received by me for the leaves for pre-
paring the drug. In native medicine it
is much used in cases of diabetes.
B. P.—The word ‘' pea” is very loosely
used. The true peais Pisum sativum;
but we have ‘‘chick-pea” (Cicer
arietinum) another name for common or
Bengal gram, ‘‘pigeon pea” (Cajanus
indicus) better known as dhall, and so
on. The term ‘‘bean” is even more
incorrectly employed, as in cocoa bean,
coffee bean, &c.
B.—The king orange is not often’ seen
in our local markets, and the pity is
that it is not more cultivated to the
exclusion of inferior kinds. It has been
introduced into the United States where
it is very highly thought of. The
Americans are getting the best things of
the Hast in Agriculture and Horticulture
through their ‘‘ explorers.”
BREEDER.—You are confusing rinder-
pest and foot-and-mouth disease. It is
better to avoid the term ‘“ cattle-plague ”
which is too general. Comparatively
speaking, foot-and-mouth disease is a
mild disease compared to rinderpest,
which practically does not admit of
treatment once an animal is affected,
and must be dealt with by preventive
measures, chief among which is the
process of serum-inoculation.
S. C.—With reference to your enquiry
whether there are any wax-excreting
palms in Ceylon, and_ whether the
Carnauba wax palm of Brazil and that
of Colombia could be grown here, Dr.
Willis, Director, Royal Botanic Gardens,
Peradeniya, reports :—‘‘ There are none
in Ceylon. The Brazil species inhabit
the mountains, and have never so far
succeeded in Ceylon.”
Mrs. H.—The numberof hens you ought
to allow for each cock-bird to ensure
fertilizing of eggs is, according to the

Government Veterinary Surgeon, six,

Minoreas. Healso states that a cock-
erel may be used for two years,
W. D. C.—In reply to your enquir
whether rubber plants should be fOpned
at a certain period, and if so at what age,
what height, and what season, the
Government Agricultural Chemist kindly
furnishes the following reply :—“It is
better not to top the trees at allas the
heavy heads induced are liable to be
broken off by any severe wind.”
ness, Messrs. Walker, Sons & Co. report
that they have two ploughs that they
think might suit, Howard’s Cingalese
Plough (Rs. 22°50) and Massey’s pipe
plough (Rs. 17°50). These are intended
for furrows 6’ to 8” deep, but with some
adjustment might-suit the purpose.
S. R. B.—The hairy beans you send
are Mucuna pruriens. The seeds need
very careful cooking. It is necessary to
first boil them two or three times, throw-
ing away the water after each boiling,
If this is not done they are apt to act as
an irritant poison.
W. D.—In reply to your enquiry
whether it is true that several varieties
of Durians are found in the Malay
Peninsula, some of which are superior
to the locally-grown variety, the Curator
of the Royal Botanie Gardens, states
that the Durian trees at Peradeniya are
very variable in their fruits, varying in
size, shape, flavour and quality of pulp.
Two trees in the Gardens yield distinctly
better fruits than the others, but even
these are distinct from each other. The
trees also vary in productiveness, some
being almost barren, while others are
extra prolific. Selection and high eculti-
vation are carried on to some extent in
the Straits, Burma, &c., so that it is
quite possible they have better varieties
than those in Ceylon.
P. M. C.—The following, as I under-
stand, are the questions raised by you :—
(1) Is there any relation between the
time taken by paddy to come to maturity
and the return it gives? (2) Are there
any statistics giving average yield of
paddies of different ages? (8) Isthere
any relation between ‘“‘ age” and qual-
ity ? I would reply to these as follows:
(1) There is, as a rule, adefinite relation
between length of growth and yield, e.g.,
a5 or 6 months’ variety yields more than
a60 day or3 month paddy. (2) There
are no statistics available, but, accord-

ing to Mr. W. A. de Silva, some such
proportion as the following may be laid
down :—
Given that a 5 mos. paddy will give a yield of 100 /
thena 2 ,, 40 np af ay 60';,
anda 3.4, 0 ag ‘i e, OLA
But sometimes a4 month paddy will
be found to give as much as a dor
6 months’ variety. In fact, 4, 5, and 6
month paddies should be classed _ to-
gether, while those of lesser age must
be put down as ‘“‘ bala wi,” which gives a
comparatively low yield, though most
useful when cultivation has to be
undertaken late in the season, (8) 1 do
not think any relation has been noticed
between ‘“‘ age” and quality.
K. B. B.—With reference to your
enquiry about the prospects of lemon
grass cultivation in the Central Pro-
vince, the Government Agricultural
Chemist states that although the grass
grows successfully, the present prices
are too low for profitable cultivation.
The cost of a small plant, for say from
50 to 75 acres would be about £250.
W. E. M.—A trial of nitro-bacterine
was made in May last year at the Govern-
ment Stock Garden. The culture for
groundnuts (Arachis hypogoa) was mix-
ed with water according to the directions
given, and, in one case the seeds were
immersed inthe liquid before plant-
ing; in another, the seeds were first
planted and subsequently watered with
the fluid ;in a third, the seeds (unino-
culated) were watered with plain water.
Except fora slightly higher percentage
of germination in the case of the first
plot (which is hardly to be attributed
to the culture), there was no striking
difference between the inoculated and
uninoculated plots, a result which
leads to the conclusion that the action
of nitro-bacterine in the case of garden
soils at least is inappreciable.
V. M. M.—‘ Vaporite ” is recommended
to be forked into the soil to rid it from
gall worms and other ground pests.

MINUTES OF THE 45TH MEETING.
The 45th Meeting of the Board of Agri-
culture was held at the Council Chamber
on Wednesday, the 7th April, 1909.
His Excellency the Governor presided.
There were also present :—Sir Solomon

BUSINESS.
1. Minutes of the previous meeting
held February 4th, 1909, were read and
confirmed,
2. Progress Report No. 44 was
adopted. Mr. Lock advised that only
one good variety of maize seed (eg.,
Hickory King) be distributed at a time,
in view of the tendency to c1oss-fertili-
zation in maize.
3, Statement of Expenditure to the
end of March was tabled.
. Mr. Lock’s paper entitlec
New Rubbers” was taken as read.
5. Mr. W. A. de Silva read a sum-
mary of his paper entitled ‘‘ Suggestions
for a local Scheme of Agricultural
Edueation.” The Director of the Royal
Botanic Gardens and the Director of
Public Instruction, in the course of
their remarks, thought the curriculum
was rather tooambitious. Mr. Harward
had acourse of agricultural lectures for
teachers in contemplation, and was also
endeavouring to arrange for the train-
ing of an agricultural instructor for the
Government Training College. H. HE.
the Governor, in thanking the writers
of the two papers submitted to the
meeting, thought that Agriculture
should be the basis of a village school
curriculum. His Excellency had him-
self drafted a comprehensive paper on
the subject of agricultural education
which he proposed to submit to a special
“The
‘committee for their advice regarding
the technical details.
Mr. Lock exhibited specimens of
Maize in illustration of a fundamental
point in plant breeding.
6. Mr. Green read a memorandum on
sericulture prepared by the Secretary,
and also exhibited samples of silk yarn
made in Paris from locally grown
cocoons.
7. Before the close of the meeting
Ht. E. the Governor said that he desired
to express his thanks to the gentlemen
who had acceded to his request for
suggestions as to the best means of
administrating loans to cultivators, and
expressed his intention of drafting, at
an early date,a scheme for local agri-
cultural banks.

Movements of Officials —The Secretary
toured in the Kandy District, Pasdun
Korale East, and Kurunegala District.
Mr. S. Rothwell, at present studying
tropical agriculture at Peraderiya, ac-
companied the Secretary on some of his
visits of inspection.
Agricultural Instuctors.—There are
now five Agricultural Instructors en-
gaged in inspection and demonstration
work, at present distributed as follows:—
Mr. N. Wickremaratne in the Bentota-
Walallawiti korale, Mr. L. A, D. Silva
in the Hambantota-Matara Districts,
Mr. S. RB. Breckenridge in the Batticaloa
District, Mr. S. Chelliah in the Jaffna
peninsula, and Mr. W. Molegoda in the
Nuwara Eliya District.
Branch Societies.—Three new Branch
Societies have been organized at Ham-
bantota, Bentota and Agalawatta (Pas-
dun korale).
The Hambantota Branch (designated
the Magam Pattu Agricultural Society)
absorbs the Tissamaharama Cultivators’
Association. It hasin view the estab-
lishing of an experimentai garden, for
which Mudaliyar C. F. S. Jayawickrema
has offered an area of land on. his Rana-
keliya estate. Agricultural Instructor
Silva, who has inspected the land, while
agreeing that the sites are suitable for
the purpose, is of opinion that their dis-
tance from a frequented centre is a
drawback.
The Bentota Branch was inaugurated
at a meeting held at Bentota in the
first week in March, when Agricultural
Instructor Wickremaratne was present ;
office-bearers will be elected at a later
meeting, when rules and a programme
of work will also be framed. Nine
Vidane Arachchies undertook toconduct
experiments in transplanting paddy.
An inaugural meeting was held at
Agalawatta on March [4 to establish a
Branch Society for Pasdun Korale East.
The meeting was attended by the Secre-
tary, and there was a large gathering,
over which Mudaliyar Samarasinha pre-
460

sided. Office-bearers were appointed,
and a resolution was passed that three
experimental gardens hbe_ started at
Bellana, Agalawatta, and Warakagoda.
The Mudaliyar’s proposals with regard
to the work of the Society were met
with general favour.
The Dumbara Society, which is among
the most active of the branches, held
its annual general meeting on February
6, when the Hon. Mr. J. P. Lewis, Govern-
ment Agent, Central Prcevince, presided.
An interesting annual report was sub-
mitted by the Secretary, Mr. Rasanaya-
gam, Mudaliyar, dealing chiefly with
the work of the Co-operative Credit
Bank. The report is reproduced in the
Society’s Magazine for February.

Imperial International Exhibition,
Nagpur.—As previously reported, the
Society sent a representative exhibit of
local commercial products to this Exhi-
bition. The Secretary of the Exhibition
Committee, writing after the close of the
Exhibition, states: ‘‘I think the exhibits
as a whole attracted attention. Of indi-
vidual exhibits, J am not at this moment
efficient to speak, chiefly because I was
absent the greater part of the time.
There were to my knowledge, however,
inquiries with regard to cardamoms and
cacao. I will see that a report is sent.”
Eaperimentat Gardens.—In addition
to the gardens at Tissa and Pasdum
Korale East already referred to, it is
also proposed to establish gardens at
Jaffna, Anuradhapura, and Batticaloa,
under the supervision of the Agricul-
tural Instructors stationed in the North
ernand Eastern Provinces, :
\
eee
; May, 1909.)
The Bandaragama and Balangoda Gar-
dens continue to make satisfactory
progress.
Horetuduwa Garden.—In August last
another stage was reached in the arrange-
ments for opening this garden. The
drawing up of the deeds for the trans-
fer of land for the purpose was entrusted
to the donor’s Notary, and there was
a prospect of the garden being taken in
hand in September and got ready for
planting during the north-east monsoon.
The unexpected death of the donor in
the interval has now caused further
delay, and will have to wait action by
the executor of the estate. It should be
mentioned that the late Sri Chandra-
sekera, Mudaliyar, donated a sum of
Rs. 2,500 for the upkeep of the garden,
so that by his death the Society loses
one of its most liberal supporters.
School Gardens.—School gardens are
increasing in number, At the end of
last year their total number was 180.
Some of the gardens in the outlying
districts are doing excellent work, as
the following log entry, made by Mr. F.
Lewis of the Land Settlement Depart-
ment, goes to show. Angunakolapilessa
school referred to is situated in a remote
part of the. Magam pattu: -‘‘I visited
the Angunakolapilessa school this morn-
ing at 7-30, just as some of the boys were
arriving. 1 was particularly struck
with the school garden, which, consider-
ing the climatic conditions that prevail
here, shows that the schoolmaster has
paid great attention to it, and with
excellent results. I noticed among other
products chillies, ash and red pumpkins,
tomatoes, sweet potatoes, Indian corn
and cotton, The crops produced were
very large, and, seeing that the water
required for the plants is brought from
a tank or well about one-eighth of a mile
distant, it is all the more astonishing
that so excellent a result is to be seen.
Altogether the garden is a fine object-
lesson, not only fer children but for
adults, as showing what can be done
here. The figures of crops given by the
schoolmaster show that the yield is
highly profitable, and I trust that the
Agricultural Department will take the
matter up, as showing the possibilities
in this wild and little-populated country,
The school garden affords a proof that
with water anda little care and atten-
tion the common garden produce of the
country can be made very profitable. I
find that some of the children, to whom
I put a few questions of a practical
character, were able to answer with
promptness and correctly. This and
the foregoing remarks about the garden
will serve to show that the schoolmaster
has done his work well, and deserves
461
Mascellaneous:
considerable ecredit considering the
materials he has to work upon.’
Public Pasture Grounds.—The question
ot providing communal pasture land is
being taken up in Uva, Gampola, and
the Wellaboda pattu. The Government
Veterinary Surgeon recommends that
there should be 100 acres of pasture for
every herd of 100 head of cattle.
The Secretary during his visit to South
India in December last found that much
value was placed upon a pasture. grass
new to Ceylon, identified by Mr. J. F.
Jowitt as Cenchrus biflorus, and is now
makioag arrangements to introduce it
into the Island in connection with the
pasture experiments referred to.
Paddy.—At the request of the Depart-
ment oi Agriculture, Beira, twelve select-
ed varieties of low-land and up-land
paddy were forwarded to Portuguese
Kast Africa for experimental purposes.
The thanks of the Society are due to
Messrs. A. P. Goonatileka and J. H. Mee-
deniya, R,M., for furnishing the paddies.
Highteen varieties of Ceylon paddy
were also forwardsd to the Department
of Agriculture, Central Provinces, Nag-
pur. These were secured with the kind
help of Mr. Sam W. Perera of H. M.
Customs.
An experiment in transplanting paddy
was carried out last season under the
direction of Mr, Wirasinha, the Mudali-
yar of Rayigam korale, His report is ex-
pected immediately, but Mr, Wickrema-
ratne, Agricultural Instructor, who
visited the district just before the cut-
ting of the corn, reported that the
superiority of the transplanted crop
was striking, the average number of
shoots froma plant being above twelve
and the ears proportinately large,
An experiment was also conducted at
Bombuwala in Kalutara totamune in
a field belonging to the Vidane, It was
carried out under many disadvantages
owing to having been begun too late in
the season, which did not allow of the
plants remaining sufficiently long in
the nursery or of sufficient time being
given for the action of the manure
applied. Details of the experiment will
be duly published together with those of
the Rayigam korale experiment,
The Mudaliyar of Pasdun Korale East
reports that transplanting will be under-
taken in the six Vidane Arachchies’
divisions of the ko.ale during the next
yala; similar experiments will be con-
ducted in the Bentota-Walallawiti
korale by the Vidane Arachchies of
Urugasmanhandiya, Kosgoda, Elpitiya,
Pitigala, Horangalla, Weihena, Opata,
Constable Arachchi of Urugaha, and
Police Officer of Amugoda.

The Teacher, boys’ vernacular schooh
Kankaniyamulla, reports that he sowed
two measures of paddy in a nursery on
August 20 and planted out the seedlings
25 days after. The crop was gathered
on February 5 and realized 98 measures,
or 49-fold, in spite ot its having suffered
somewhat from the attacks of rats and
birds. The school boys assisted in the
experiment.
Drought-resistant Paddy from Burma.
—This paddy was distributed among
the following centres :—Anuradhapura,
Chilaw, Delft, Hambantota, Jaffna, Ka-
tana, Katunayaka, Kegalla, Kurunegala,
Mannar, Mullaittivu, Nattandiya, Trin-
comalee, Vavuniya, Wanni hatpattu,
and Puttalam.
A report of the failure of the last
paddy crop comes from the Marawila
district, with a request for assistance
with seed paddy. The matter is receiv-
ing attention.
A useful pamphlet on paddy eultiva-
tion and manuring has been issued by
Messrs. Freudenberg & Co., and can be
had free on application. The contents
are instructive, and copies received from
the publishers have been distributed
among Branch Societies.
Seeds and Plants.—Through the cour-
tesy of the Director of Agriculture, Beira,
four varieties of cotton (Champion Clus-
ter, Southern Hope, Bate’s Big Boll,
and Allen’s Long Staple) and six of
maize (Golden King, Hickory King,
Chester County Mammoth, Champion
White Pearl, Karly Star Leaming, and
Iowa Silver Mine) were received during
May, and distributed,
Soy Bean.—This bean was imported
twice previously, but did not prove a
success. At the request of a member,
seeds of eight varieties were obtained
through the courtesy of the United
States Department of Agriculture, and
are being triedin the Kurunegala Dis-
trict. They are named Mammoth,
Haberlandt, Tokio, Guelph, Itosan,
Brownie, Flat King, and Nuttal.
Dhaincha Seed (Sesbania aculeata).—
Arrangements are being made, if pos-
sible, to get a fairly large supply of seed
of this green-manure plant.
The Algaroba Tree (Prosopis juli-
flora).—At the suggestion of a member,
seeds of this useful tree have been in-
dented for from Hawaii. A specimen
about six years old may be seen growing
in the Government Stock Garden.
Alphonso Mango Grafts indented for
from India, and the usual stock of vege-
table seeds from England, for south-
west monsoon planting, are expected to
arrive early next month.
[May, 1909.
Kekuna Nuts.—A report is awaited
from the continent on samples of this
oil-nut (Aleuwntes triloba), submitted
in connection with inquiries received.
Some seven oreight years ago an order
for this oil came from Russia, and was
executed with the help of the Superin-
tendent of School Gardens. So far as
could have been ascertained, it was
wanted in connection with the paint
trade.
Yams.—What is generally known as
the Jaffna yam or King yam—a variety
of Dioscorea alata, purple when boiled—
is considered a delicacy by many, and
a gcod deal sought after. It is gener-
ally procured from the Northern Pro-
vince, as very little is raised in other
parts of the Island. To test the market
value of the yam a member grew some
100 vines and got a crop of over a_ 1,000
pounds, but, strange to say, he was un-
able to get a better sale for the produce
than for that of commoner varieties
more popular with the natives (such as
hinguratla).
A consignment of selected Ceylon
yams was despatched to Manila at the
request of the Director of Agriculture.
The Yampee or Kush-Kush yam of
the West Indies (Dioscorea trifida) has
proved too delicate for the compara-
tively damp climate of the Western Pro-
vince. The vines grown at the Govern-
ment Stock Garden have all died out
in spite of attention given.
Implements and Machines.—A trial was
recently made at the Government Stock —
Garden by Messrs. Brown & Co. of
a Hornsby mower for bullock-power,
recommended for cutting down weeds
in coconut plantations. In the absence
of woody-stemmed weeds it did its
work satisfactorily.
Messrs. Walker, Sons & Co. have on
view a varied assortment of Hnglish
and Indian implements, which are worth
inspection by those whoare in search
of suitable ploughs, &e.
White Ant Exterminator.—The Govy-
ernment Entomologist reports:—‘‘ White
auts are easily exterminated by the
machine imported for that purpose and
now sold by Messrs. Gordon Frazer
& Co., Colombo, for Rs. 75 each. They
have proved very successful, and the
extermination is complete.”
Oil Mills.—There is a prospcet of
Messrs. Walker, Sons’& Co. exhibiting
and demonstrating the working of a
Donaldson’s patent oil mill (referred to
in last Progress Report) at the next
Agri-Horticultural Exhibition at Galle,
to be opened on June 16. Members
will thus have an opportunity of judg-

ing of the merits of these up-to-date
appliances and compare them with the
crude chekku-mills of the country.
Any one desirous of trying the
Duchemin Fibre Machine can do so by
application to the Superintendent of
School Gardens.
A simple hand loom may be seen at
work at the Government Stock Garden,
where two of these weaving machines
are under trial, It isinteresting to learn
that the weaving ofcloth is now being
carried on in the Welikada jail. A loom
introduced by alate vistor to Siam will
probably be shown at work at the
Kandy Show next August.
Sericulture.—A consignment of Jive
Eri cocoons is expected shortly from
Assam. Applications for eggs should
be made to the Superintendent, School
Gardens.
The following report has been received
from a Swiss firm in the silk trade ona
sample submitted :—‘‘We very much
regret not to be able to give you a
satisfactory answer as regards the com-
mercial value of Eri-pierced cocoons. To
do this we ought to make a trial ofa
certain importance, but till now we
never heard of large quantities we can
rely on, which should amount to 200,000
pounds a year atleast. If one day you
should be able to give us exact informa-
tion on this score, we should decide upon
the matter.”
A Paris firm, to whom samples were
forwarded some time ago, writing on
February 20, reports that the trial of the
cocoons will be finished in a few days
when a full report will be sent. Ina
previous letter the same firm reported :—
‘““We duly received your favour of
October 13 last, and since we have seen
in our mill the parcel of 50 lb. of Eri
cocoons you have sentus. The reason
we did not write to you earlier was that
our Manager, Mr. Villy, wanted to see
those cocoons with Mr. Strohl before
working them. We have chosen all the
brown cocoons left in the white ones so
as to enable usto make dyeing trials,
and to see how we can use this quality.
We are dressing and _ spinning’ the
cocoons now, and shall be able to give
you further reports in a short time.
You may be assured that we give all
our attention to this question, and that
we hope that it will later on bring some
interesting business, We think that
since Mr. Strohl’s visit you have been
able to study the question of making an
important practical trial of Hri cocoon
culture, and would be glad to hear what
the cost of sucha trial could be. If the
trials of spinning we are making now
give a good result, we shall do what we

can to facilitate you a large trial of
practical culture. We think that such
a trial will be absolutely necessary to
show the cost of price of those Eri
cocoons, and to allow on one side the
producer and on the other side ourselves
to see what the interest of this business
ce ould be for each other,”
A small experiment in the extraction
of Eri silk fibre and spinning it into
yarn is about to be tried at the Govern-
ment Stock Gardens.
Cotton.—The local agents of the Brit-
ish Cotton Growing Association, in
reply to aninquiry from a cultivator,
report as follows :—‘‘ There is a combine
of Moormen who buy both cotton and
kapok in 2nd Cross Street, Colombo,
besides most of the Kuropean firms buy
both products, and we ourselves should
be happy to compete. The best results
are obtained by the planter if he allows
us to gin, bale, and ship the cotton for
him, as by doing so he would reap the
advantages of a rising market, while
merchants have to take into consider-
ation a possible sudden drop in the
market and have to keep their quota-
tions accordingly low. Our charges for
ginning, baling, and putting on board
f.o. b. are 7 cents per pound of clean
cotton, and for kapok the charges are 4
cents per pound hand-cleaned and 6 cents
machine cleaned.”
Manure.—A series of experiments in
the manuring of vegetables is being con-
ducted at Jaffna by the Agricultural
Instructor of the Northern Province.
The Superintendent of School Gardens
has recommended the following mixture
for oranges :—

Ground nut Cake aes cet 24
Bone Phosphate 6 Act 5
Sulphate of Ammonia... ae $
Sulphate of Potash ... ae 1
Salt and Citronella Ash for Coconut.—
The Government Agricultural Chemist
reports as follows on samples submitted
to him by a member:—‘‘I consider
sample of salt submitted suitable for
young coconut trees at the rate of one
pound per tree forked in round the tree
about three feet from the trunk.
Similarly applied the ash of citronella
grass would be suitable at the rate of
5 pounds per tree.”
Mosquito Exterminator.—A few pack-
ets of a preparation under the above
name were received from a mem-
ber, and have been distributed in
malarious districts for trial and report.
The preparation is said to be made of
local vegetable products (chiefiy Mar-
gosa leaves) and not to contain any

del:terious ingredients. It consists of
a powder for fumigation.
Tobacco.—Samples of tcbacco forward-
ed by the Dumbara Society were sub-
mitted to the London tobacco leaf
expert referred to in the last Progress
Report. Writing on February 19 he
says:—‘‘I have carefully examined and
inspected these growths, and I have
also got two or three of the largest
manufacturers to try a little of the
same. Itis certainly the best attempt
I have seen with tobacco outside
Kentucky, and I feel sure that if it
is properly put up there will be a
future before it, but the samples are far
too moist, and should be dried down
to contain about 12 per cent. moisture
and might fetch 5d. to bd. per
feel sure that a large trade can be
done withit. Of course, I mention the
above prices with reference to the
present market price at Kentucky, and,
asI have previously stated, British
manufacturers are very conservative,
and itis very difficult to get an outside
growth like this on the market, unless
you give them an advantage in price. I
shall be pleased to know what quantity
you can offer. It certainly burns well,
and has a distinctive flavour; but the
latter fact may be derogatory rather
than otherwise. The samples sent con-
tain about 20 per cent. moisture, which
should, as before stated, be reduced to
about 12 per cent. The thick part of the
stalk should be butted and the sand
well shaken out. If labour is cheap, it
might be advisable to have the tobacco
stripped before importing. lt would
sell more readily, and a better price
might be got. The two lowest grades,
Iam afraid, would be useless for the
English trade, and I do not think it
would pay to import them.”
Disease in Nutmeg Trees.—Mr. Fre-
derick Lewis of the Land Settlement
Department reported last year that he
had observed a disease in nutmeg trees,
which attacks old trees, commencing
from the top branches, causing a change
of colour in foliage from adark green toa
pale sickly yellow, till finally the leaves
fall off, exposing dead twigs and
branches.
The Government Mycologist, after
inspecting the affected trees, reported :—
“They are evidently suffering from a
root disease, which gradually kills the
roots and causes the branches to wither
back from the tips owing to stoppage of
the water supply. I was informed that
the tree died outright within six months
of first showing symptoms of disease.
November should have been the best
time for colecting
fungus, but it had been too dry, and
specimens of the_
[MAY, 1909.
nothing but mycelium was observed ; it
would require continuous observation
during the wet weather to find the
fructification, which is most probably a
Polyporus. In most cases white ants
had eaten away the base of the tree
and spoilt all chance of obtaining the
fructification. Under the _ circum-
stances, itis difficult to know what to
advise. The caretaker gathers the crop,
but has presumably no other interest in
the matter. The dead trees should be
burnt and their roots dug out as far as
possible, but as the living trees are of -
very little economic value no one will
be eager to spend anything. The jak
trees here are also attacked by a root
disease, and the dead trees should be-
similarly dealt with, Apparently most
of these trees are growing in pure
cabook, which was excavated when the
reservoir was made. They can scarcely
be expected to flourish in such ‘soil,’
and if it is wished to maintain the
surroundings as a garden, shrubs should
be planted in holes filled with good soil.”
Orchella Weed (Rocella montagnie).—
At the instance of the Imperial Institute,
London, inquiries were instituted as
to the probable cause of the falling
off in the trade in this dye stuff—
a lichen found chiefly in the north
of the Island growing on coconut
and jungle trees. The export at one
time was as much as 1,157 ecwt., and
the price £36a ton. Now the price quoted
is Rs. 180 c.i-f., and the falling off in the
trade is generally attributed to this
reduction in price.
Cattle Disease.-—The year began badly
for cattle owners owing to the pre-
valence of rinderpest, which has caused
great loss, chiefly in the Province of
Uva, and is still causing the Veterinary
Department much anxiety. The constant
menace which daily importations of
cattle from India have been to the
health of our local stock has now been
practically removed by the opening of a
Central Cattle Mart and Segregation
Campin Colombo. The establishment is
presumably the first of its kind in the
East, and is well equipped and under
good management.
Publications.—An Agricultural Calen-
dar in Sinhalese is in type, and will be
issued early.
Leaflets on the Rice Bug or Paddy Fly
(No. XL.) and Nitrogen-gathering Crops
(No. XLII.) have been printed and dis-
tributed. Leaflet No. XLII. on “The
Silk Cotton Tree” is in the hands of the
printer.

{Paper read before the Board of Agri-
culture on April 7 by Mr. W. A. de Silva.]
Any scheme for agricultural education
in Ceylon should be based on elementary
lines, and a systematic attempt made to
give the village children a suitable
training to enable them to make the
best use of their surroundings.
The school gardens now in operation
have been devised to partially meet this
want, and the work in such gardens
should be madea regular part of the
general workin a primary school and
not relegated to off hours.
Five hours are now usually devoted in
a village school to the teaching of letters,
This can well be reduced, and the time
thus saved devoted to practical teaching.
In the first instance, provision should
be made to give the teachers in village
schools some instruction in the subject
to enable them tointerest their pupils
in agricultural work. This can he done
in two ways—
(a) By short holiday courses of
lectures to teachers,
(6) By training the teachers for a
short period at an agricultural school.
The annual lectures on sanitation
given to teachers in grant-in-aid schools
have proved to be of very great use to
them. Similar courses of lectures and
demonstrations in agriculture can be
arranged at a very little cost.
The classes can be held in August and
December during school holidays, and
should be open toall vernacular certi-
ficated teachers employed in Govern-
ment or grant-in-aid schools, the number
attending a course of lectures and
demonstrations being limited to about
fifty at a time. |
Those selected to attend the classes
should be paid a commuted sum of
Rs. 20 to meet their travelling and living
expenses during the time they are
engaged in attending the classes.
Such teachers who pass an examina-
tion after the classes should get a certi-
ficate, and should be entitled to an
annual bonus when they show satis-
factory results at the examination of
children in their respective schools.
The following may form the basis of a
provisional syllabus for the teachers’
course of lectures and demonstrations in
agriculture : —
First day.—TwHe Sow: What it is.

Agricultural Schools.—The training of
teachers and others directly interested
in agriculture for a Short period of at
least one year should be organized on
some definite lines.
With this view aschool of agriculture,
where teaching will be imparted in the
vernacular, should be established some-
what on the lines of those now in
operation in Ireland, where the students
should be in residence during the period
of thei: course of study. This school
should be located, as fac as possible, at
some convenient centre, such as the
Henaratgoda Gardens. The establish-
ment should be placed in charge of a
Principal, who should be a _ trained
teacher and who can be assisted by a
staff possessing special knowledge of the
subject of teaching.
The importance of appointing trained
teachers for guiding establishments of
this nature is now fully recognized, and
the Indian Department of Agriculture
has appointed them with successful
results.
All teaching should be carried on in
the vernacular or, where necessary,
through interpretation.
Students admitted to the school should
be between the ages of 14 and 21, and
should have at least passed the Fifth
Standard in a Government or grant-in-
aid school, or should be able to pass an
entrance examination of a _ similar
standard.
These students may be of three
classes—
(a) Those who have been nominated
by Government Agents as fit persons to
be appointed as village headmen.
(b) Those who have passed the Govern-
ment teachers’ examinations and who
desire to obtaina training in practical
agriculture.
(c) Those joining on their own account
and paying for the training received.
There should be two sessions of teach-
ing during the year, and not more than
thirty students should be admitted each
term. Thus the institution will have
sixty students at a time,
[May, 1909,
Selected candidates should be housed
at the place where they are to receive
their training, and should be under the
discipline of a tutor. The course of
instruction should be mainly practical
with as little use of books as possible.
In addition to the Principal, who
should be a trained teacher from a
recognized institution, the services of a
Field Instructor might be secured from
India, and the lectures and ordinary
practical work arranged in sucha way
as to enable the students to receive their
instructions in special subjects from the
scientific staff now in the service of
Government.
Provision should also be made for
obtaining the services of an assistant,
who has obtained an Anglo-vernacular
teacher’s certificate from the Govern-
ment Training College, and who should
assist the Principal, and among other
things undertake the work of interpret-
ing the lectures.
The syllabus of studies should include
instruction in agriculture, with outdoor
classes in dairying, horticulture, bee-
keeping, veterinary hygiene, pests, and
diseases of plants, and the elements of
chemistry and botany. Instruction in
woodwork and ironwork, as far as it
relates to farmers’ work, and the use of
tools and implements, should also be
included in the curriculum.
A school on the above lines will be
able to train a number of teachers in the
general principles and practice of agri-
culture, to enable them to introduce the
teaching of agriculture in village schools.
It will also be the means of securing a
class of village headmen, whose training
will enable them to take an intelligent
interest in village agriculture, and
generally promote the welfare of the
villager.
The next question that should be
considered is the provision of teachers
for the agricultural training school and
for the schools of agriculture which may
eventually be opened in different centres
of the Island. For these posts a class of
men with a sound knowledge of agri-
cultural science and_ practice will be
required. They should possess a good
knowledge of the vernaculars, and
should also have a training as teachers
if they are to do useful work.
In order to obtain men with these
qualifications, a number of scholarships
should be offered annually to the
students of the Anglo-vernacular class
of the Government Training College,
Colombo, to enable them, after they
obtain their certificates at the Training
College, to proceed to an Agricultural
PWT tae |
‘May, 1909,]
College in India to receive an advanced
training in the science and practice of
agriculture. The Agricultural College
at Coimbatore or Pusa (preferably the
former) will suit the requirements of
Ceylon students. The course of studies
at these institutions extends for a period
of three years.
The higher scientific staff of agricul-
tural experts also requires organizing
in the light of experience gained in India.
It has now been settled that local ex-
perience is invaluable for useful work
by the expert officers, and this local
experience is supplied by attaching a
qualified assistant, who is a native of
the country, to each member of the
scientific staff. At the Agricultural Col-
leges ard Experimental Harms teaching
is done through these assistants, whose
work is supervised and directed by the
experts recruited in Kurope. These
assistants are not mere subordinates,
but are colleagues whose education and
emoluments bring them in very close
contact with the experts, and who are
able to act for them in their respective
capacities during the absence of the
experts. Thisis a matter that requires
very careful attention in the organiza-
tion of a successful scheme for the im-
provement of the agricultural interests
of the country. It may be possible to
draw these assistants from the students
of our Colleges, and it seems reason-
able to divert one of the two Uni-
versity Scholarships given annually to
students in Ceylon tor this purpose,
requiring the winner of the scholarship
in science and mathematics to arrange
his course of studies in a European or
American University in order to qualify
himself to take one of these posts.
To summarize. (1) The system of
teaching in village schools require modi-
fication with a view to the introduction
of training in village industries along
with that of letters,
(2) As apreliminary step, a holiday
course of lectures to teachers in verna-
cular schools should be organized on the
lines of lectures on sanitation now given
annually to teachers.
(8) Those seeking posts as village
headmen should get an elementary train-
ing in agricultural industries as resident
pupils in an elementary vernacular agri-
cultural school established for the
purpose.
(4) A number of village teachers
should also be encouraged to take their
training at such a school,
_(5) An elementary agricultural school
for resident pupils with a one year’s
course, where teaching is imparted in
the vernacular, should be established on
467
Miscellaneous.
similar lines to schools now established
in Ireland and other places.
(6) The school should bein charge of
a trained teacher, assisted by special
teachers, and the lectures on _ special
subjects given by the agricultural ex-
perts now in the employ of the Govern-
ment.
(7) Eventually, village agricultural
schools should be established at suitable
centres.
(8) Teachers for such village agricul-
tural schools should be obtained by
offering annual scholarships to a num-
ber of students passing out of the Anglo-
Vernacular class of the Government
Training College, Colombo, to enable
them to go through a complete course
of training at one of the Agricultural
Colleges in India.
(9) That the staff of scientific experts
in agriculture should be strengthened
by the appointment of well qualified
assistants from among the people of the
country to act as colleagues of the
scientific experts.
(10) That one out of the two Univer-
sity Scholarships now awarded by the
Government of Ceylon’ should’ be
diverted to the training of scientific ex-
perts at European or American Univer-
sities on lines similar to those adopted
by the Indian Government in awarding
Technical Scholarships for training
Indians in Kurope and America.

DR. FRANCIS WATTS, C.M.G., AND
HIS WORK IN THK LEEWARD
ISLANDS.
The departure of Dr. Francis Watts,
c.M.G., from Antigua, in order to take
up the work of Imperial Commissioner
of Agriculture for the West Indies, has
been the occasion of a number of reso-
lutions of a complimentary nature from
Agricultural bodies in the Leeward
Islands. :
At a meeting of the Antigua Agricul-
tural and Commercial Society, held on
January 15 last, it was resolved by the
members present, ‘That this Society
tenders to Dr. Watts its heartiest con-
gratulations on his well-deserved pro-
motion to the important and responsi-
ble post of Imperial Commissioner, The
resolution went on to express the regret
of the Society at the departure of Dr.
Watts from the colony in which he
had worked for the past twenty years
with great benefit to the community at
large, as well as its satisfaction that in
his new position the Commissioner would

mon with other West Indian Islands, the
benefit of his experience and advice in
agricultural matters.

NITRO-BACTERINE AND GREEN
MANURING.
LEGUME BACTERIA.
By S. F. EpwWARDs AND B. BaRLow,
Bulletin No. 169 of the ¢ Ontario Depart-
ment of Agriculture.
A somewhat heated controversy has
recently been raging in the pages of
gardening and scientific papers at home
as to the precise value of vertain cultures ~
intended to encourage the growth of
the nitrogen-absorbing nodules upon the
roots of leguminous plants. As most of
those interested in agriculture are now
well aware, the majority of plants of
the pea and bean family, which includes
such well known local representatives
as Crotalaria, Albizzia and Dadap, pos-
sesses the singular power of absorbing
and fixing the free nitrogen of the air and
making use of it as food. This power
depends upon the presence, within cer-
tain lumps or nodules borne upon the
roots of the plants, of particular forms
of minute bacteria, which are gifted
with the exceptional faculty of accumu-
lating nitrogen. Within the last few
years it has been found possible to iso-
_ late these bacteria from the leguminous
plants which constitute their natural
habitat, and to induce them to grow and
multiply in artificial surroundings and
upon artificial food.
So far the matter was one of purely
scientific interest. The question next
arose whether these artificial cultures
might not be made use of to encourage
the growth of the nodules upon the
roots of leguminous vegetables and
other useful plants belonging to the
same family. Although a series of
attempts had already been made to pre-
pare useful artificial cultures of these
bacteria, the problem was still in a purely
experimental stage when journalistic
eyes chanced to fall uponit, with the
Yesult that the cultures were imme-
diately spread abroad, with much
flourish of advertisement, under the
name of nitro-bacterine.
As regards the value of nitro-bacterine
in horticulture and agriculture, opinions
are stillmuch divided. Careful compara-
tive experiments have been carried out
by several competent workers with a
view to determining the relative growth
and yield of leguminous crops treated
with nitro-bacterine and of similar crops
untreated. The results have been some-
what contradictory. The truth seems
to be that in some cases the soil
in which the seeds were sown was
already well provided with the neces-
sary bacteria, and that when this was
the case the addition of further supplies
made little or no difference to the growth
of the plants. On the other hand, in
soils which were poor in the particular
bacteria required, inoculation of the
seeds with cultures of the bacteria

appears to have been attended with good
results.
We have recently received a bulletin
from the Ontatio Department of Agri-
culture in which successful experiments
of this kind are described. Special cul-
tures prepared by the bacteriologists
of the department are now being dis-
tributed to the Canadian farmers.
The directions for use sent out with
the cultures are sufficiently instructive
to be worthy of quotation. They are
as follows :—

advisable to treat the clover separately,
mixing just before sowing.

We have at present no data for decid-
ing whether similar cultures would
prove of benefit in Ceylon, It is just
possible that by their aid particular
species of leguminous plants might
be induced to make good growth in
districts where they do not flourish at
present.
One of the greatest difficulties in
establishing herbaceous leguminous
plants in old and worn-out tea estates is
occasioned—at least in part—by the
absence of the necessary bacteria in
what is practically subsoil, now that
the original soil has been largely washed
away. If suitable cultures can be made
and applied at a reasonable cost, so as
practically to insure success at the first
planting of the leguminous species, a
great saving of money and time will be
effected in carrying out one of. the most
important measures available for the
improvement of a worn-out estate.
Whatever may be the value of nitro-
bacterine and other
tions in promoting the growth of legum-
inous plants, there can be no question
as to the value of the leguminous plants
themselves when returned to the soil in
the form of green manure. Inthe case
of tea cultivation the value of green
manuring has been amply demonstrated —
on the Peradeniya Experiment Station
and elsewhere. It is not possible to
name any particular plant as being the
best for this purpose—in different locali-
ties different varieties flourish best, and
Dadaps, Albizzias and Acacia decurrens
“are all good in districts suited to their
growth. On the whole we are inclined
to recommend most strongly the her-
baceous species, for instance, Crotalaria,
or even still smaller forms such as
Desmodium. Such plants not only
provide organic material which may be
returned to the soil, but they also
effectually prevent the washing away of
the valuable surface soil during the
period of their growth. It is very
possible that creeping leguminous plants —
may be found of value in rubber clear-
ings, since they may be expected to
combine the functions of accumulating
nitrogen with that of preventing the.
growth of weeds, but upon this point we
have as yet very little data available.
Numerous
leguminous plants are being collected
from all parts of Ceylon, as well as from
similar prepara-
varieties of herbaceous—
[Junp, 1909.
Bee

India, the Federated Malay States and
elsewhere. These are being cultivated
upon the Peradeniya Experiment Station
with the object of obtaining seed for
distribution and trial at different eleva-
tions and on different soils. Specimens
of the roots and nodules of each pro-
mising variety are to be sent to the
Nitrobacterine Co. for the preparation
of a special culture for each.
The habits of the various leguminous
plants which may be expected to prove
usefulin this way differ considerably.
They vary from the upright bushy
forms with more or less woody creeping
507
stems to the low creeping species which
entirely cover the soil and only attain
a height of a few inches. Some again
are of no value as food for cattle, whilst
others are grazed upon with relish. It
is possible that within a few years the
grazing of cattle upon rubber estates
may prove the best means of keeping
this crop in a vigorous and- healthy
condition. Nitrobacterine may prove
careful in establishing such leguminous
herbage, and it is hoped that experi-
ments in this direction may be under-
taken.

THE YIELD OF WILD AND
PLANTED ‘‘PARA” RUBBER.
(From the India Kubber World, Vol. 39,
No, 4, January, 1909.)
“Whatis the yield of arubber tree?
Simple as the question may appear—
and it is asked incessantly—giving aun
intelligent answer to it is by no means
simple. One must consider what
varieties of rubber are involved, where
the tree grows, whether “wild” or
‘“‘ cultivated,” and, if the latter, the con-
ditions under which planted. A remark
may be recalled here from a report by a
former British Consul at Para writing of
native Heveas in the Amazon _ region:
- ‘two trees growing close together and
under apparently precisely similar con-
ditions will often vary very much as
regards their yield.”
There is no question that rubber trees
do yield, else what would become of the
rubber market? On one day during the
past month the Customs authorities at
New York reported the arrival of rubber
of an invoice value exceeding $2,000,000.
The Custom Houseat Para dealt last
year with 80,638,800 pounds, and some
ears the figures have been larger.
Besides. the Amazon region doesn’t sup-
ply ail the rubber used. We hear over
and over again that the Brazilian rubber
is derived from trees scattered in dense
forests, and that thenative tappers gain
a very small amount of latex from each
day’s tapping. But the Para shipments
argue either a tremendous number of
wild rubber trees or a very considerable
average annual yield per tree.
Since it must be ad.aitted that trees
do yield rubber, the question remains,
how much? This subject, as relating to
forest rubber, has been treated at some
length in former numbers of The India
Rubber World, including quotations
from Mr. Vice-Consul Temple, who once
reported having had access to the books
of some operators in the Brazilian field,
indicating an average yield of 2:2 to 3:3
pounds yearly per tree. He was of the
opinion, however, that very many trees
were being worked with no larger aver-
age yield than 1l‘l pounds. His report,
however, had to do only with the state
of Para, where the rubber flelds have’
been worked longer and more thoroughly
than inthe river regions. It does not
seem to have occurred to the Amazon
rubber trade to consider the yield of
individual rubber trees so long as total
results are satisfactory. But chance
details which have come to hand from
time to time point to the probability of
a yield of 4 to 10 pounds yearly per tree,
varying -with the degree to which
estradas have been ‘‘ worked out.”
With the coming of cultivated rubber
on plantations owned by capitalists and
with shares listed on stock exchanges,
the question of yields becomes of parti-
cular interest in connection with the
analysis of company reports. If one
tree will afford a given quantity of
rubber, will 1,000 give a thousand fold ?
In considering any of the figures which
follow—all relating to the yield of plant-
ation Para (Hevea)in the Far Hast—it
must be remembered that such yields
may be influenced—
By the character of the soil. altitude,
or climatic conditions,
By the coarseness or width of the
planting,
By the frequency of tapping,
By the method of tapping,
By the care with which the latex is
handled,
Gums, Resins,
Trees with short trunks of large girth
may be more productive than taller ones
of less girth. The commencement of
tapping is determined by the size of the
trees rather than their age, and all trees
do not grow at the same rate, It may
be pointed out that even in the
most detailed rubber plantation reports
up-to-date statements of yield, as
a rule, include in one total the pro-
duce of mature trees tapped through-
out the year and that of trees just
come “into bearing,” which may have
been tapped once or twice only.
It would be desirable to have, from
each of several well-managed _plant-
ations, a record of the yield of a definite
number of rubber trees, of uniform size
and age, tapped the same number of
times in a year, by the same system,
and with the same method of treating
the latex. It is not wholly satisfying to
have included in one total a large tree
yielding five pounds or more, and a
smaller tree from which half pound or
less has been obtained. In default of
such figures the following details have
been culled from the sources most avail-
able.
In the latest edition of his ‘‘ Heve®
Brasiliensis” Mr. Herbert Wright ha%
compiled a lot of data on the yields re-
ported from rubber estates, though
without any effort to establish any rules
as to yields as related to the age of the
trees tapped. From one of his tables we
have taken twenty-three items, referring
to as many properties, on which, in 1905,
166,740 trees yielded 215,933 pounds of
rubber, or 1:235 pounds per tree. The
average per tree on one estate was as
low as ‘32 pound, the largest reported
for anyone was 5'5 pounds per tree. A
list of sixteen of those properties shows an
average yield per tree of 1°35] pounds.
Six estates showed averages per tree of
2 pounds, 2°2, 3'2, 3°25, 3°5, and 55 res-
pectively.
From another table in Mr, Wright's
book a list has been compiled of eight
estates, on which 79,631 trees, in 1906,
yielded 220,200 pounds of rubber—an
average of 252 pounds. The average per
tree on various estates was 2:03 pounds,
2:37, 2°46, 2:75, 2°79, 2:88, 3, and 7°1 pounds
respectively.
A particularly interesting item appears
in the report of the Anglo-Malay Rub-
ber Co., Limited, for the calendar vear
1907, On their Terentang estate 28,048
Hevea trees, aged 7-8 years, are stated
to have yielded 105,655 pounds of dry
rubber, or an average of 3-76 pounds per
tree. On their Ayer Angat estate, how-
ever, 14,540 older trees (9-10 years) yielded
only 42,970 pounds, or an average of
508
{JunB, 1909.
2°95 pounds. On the other hand, 5,440
trees on their Batang Bali estate mostly
only 6-7 years, thougha few were 9-10,
gave 18,112 pounds, or an average of 3°82.
The total tapping for 1907, on these
and another estate, covered 68,236 trees,
yielding 224,778 pounds, or 3°29 average.
An attempt has been made by the
writer to analyse the ages of the Hevea
trees tapped during three years by the
Bukit Rajah Rubber Co., Limited.
Taking account of the approximate ages
of their trees, so far as can be gathered
from the company’s various reports,
and their definite statements of the
number of trees tapped and their yield,
these results appear :
Year ending March 31, 1906.—Trees
tapped 34,457, yield 33,203 pounds,
average age of trees at end of period, 6:28
years, average yield per tree, ‘97 pound.
Year ending March 381, 1997.—Trees
tapped, 88,341, yield 118,982 pounds,
average age of trees, 5°94 years, average
yield 1°345 pounds. .
Year ending March 81, 1908.—Trees
tapped, 89,295, yield 163,521 pounds,
average age of trees, 7'27 years, average
yield, 1°83 pounds.
Some very definite information is
given in the report of the Highlands
and Lowlands Para Rubber Co., Limited,
tor 19U6. It is stated that on one block
of 16 acres 807 Hevea trees, 9 years old,
planted 30x25 feet, were tapped during
three periods of the year mentioned,
With these results: 2,5C0 pounds at the
first, 1,469 at the second, and 1,778 at
the third, or a total of 5,742 pounds—
an average of 7:01 pounds per tree for
the year,
During the business year 1906-7 the
Federated Malay States Rubber Co.,
Limited, collected 32,175 pounds of rub-
ber from 12,385 trees, wide planting—
averaging 2°60 pounds.
It may be added that the total pro-
duction of plantation rubber in the
Federated Malay States for 1906 was
861,738 pounds, from 441,482 trees, . of
varying ages, or an average of 1°95
pounds per tree.
From all the preceding data it would
appear safe to estimate not less than 2
pounds annually from trees, say 8 years
old, with reason to expect an increased
yield withgreater age. But much larger
yields, in exceptional cases, have been
authenticated. EHleven-year-old trees
on Culloden estate, especially tapped,
gave 14 pounds of rubber from 8 months’
tapping, and trees of unknown age (pro-
bably 20 to 25 years), from 10 to 29
pounds each in one year.

throughout the Islands. Quarantines
were instituted and a general effort was
made to interest the local officials and
communities in preventing the spread
of animal diseases. The work was more
or less unsettled atthe beginning as the
lines of procedure had to be worked out
in the provinces. Some changes were
necessary from time to time during the
first three years. This formative period
of the work has long since passed, and
it is now thoroughly organised with
definite plans which are certain to give
results if persistently followed.
The first thing done was to inspect
imported cattle to determine whether
or not they had infective diseases on
arrival. The records show clearly that
agreat many of them did bring such
diseases, especially from China.
The next step was to inspect those
cattle being shipped from ports of entry,
especially Manila, to the provinces, and
determine whether or not they left these
ports in a healthy condition. It was
found that many of them carried the
diseases to the provinces.
It was also found that where diseases
prevailed in the provinces they were
spread extensively by local cattle
trading.
The result of all these studies and
observations was to define the different
lines of action which are known to be
necessary in the suppression of the
diseases. The first of these was to estab-
lish a rigid inspection and-limit the
movements of cattle by means of quaran-
tine. The first effort in this direction
was the enforcement of the veterinary
section of the Sanitary Code of the City
of Manila, which became _ effective,
January 1, 1907. This law was held in
suspension for some months, but in due
course of time the quarantine of
imported cattle exposed to infective
diseases was undertaken. This led to
immediate and strong opposition by
certain local cattle dealers. They even
questioned the integrity of the Govern-
ment officials who had charge of enforc-
ing the quarantine. All of this agita-
tion led to a full discussion of the
subject, which finally resulted in the
passage of Act No. 1760 of the Philippine
Commission on October 12, 1907. This
in effect extended the quarantine to
infected and exposed_animals through-
out the Islands.
Strong protests against all quaran-
tines were constantly made on the
round that liberal importation of cattle
or draft purposes was necessary to
replace those which had died from
diseases in the provinces. It wasshown
in the May Review that 90 per cent. of
the cattle imported into the Islands
70
553
Live Stock,
come to Manila, that70 per cent. of these
are slaughtered in this city, and 80 per
cent. of the remainder shipped to the
provinces, are subsequently slaughtered
in the towns near Manila. So this
argument lost much of its foree. If it
were not tor prejudice, seven pounds of
meat out of every ten produced here by
imported cattle, could as well be bought
from cold storage.
After considerable agitation, General
Order No, 9 was issued April 30, 1908,
Its main feature was to exclude cattle
from the infected places throughout
the Orient. This order met with strong
opposition from the cattle dealers, and
its enforcement was suspended on
technical grounds.
_General Order No. 10 was issued and
provided a system of automatic limita-
tion of shipments from infected places.
It gave dealers time toship cattle which
they claimed to have on hand and per-
mitted three successive infected ship-
ments to be landed, However, certain
unscrupulous dealers began deliberately
importing infected animals from differ-
ent Chinese ports, changing when three
shipments had been made from each.
This was followed by the issuance of
General Order No. 12 which put all ports
on the same basis in so far as landing
of infective shipments is concerned.
Under these provisions when an infect-
ed shipment of cattle arrives in Manila,
the animals can be landed for immediate
slaughter only.
This order is the most important step
. yet taken by the Government in prevent-
ing the constant reinfection of different
parts of these Islands with rinderpest
and_ foot-and-mouth disease. It marks
a distinct epoch in the history of the
veterinary work which all thinking men
who understand this problem will
readily appreciate.
The order in itself is not complete, in
that it does not provide details for the
cleaning and distinfection of ships,
corrals, and other places from which
the infection of these diseases is liable
to spread. Anattempt has been made
to remedy this by the codification of
all general orders from No, 10 and
including the rules and regulations for
disinfecting. This constitutes General
Order No, 13, published in this number
of the Review,
There are three more logical steps
which the Government should, and no
doubt will, take in due course of time.
The first of these is to provide a means
of handling infected shipments of cara-
baos and selected breeding cattle which
are intended for slaughter. This would
be simple if there was an Island in Manila
Live Stock. 554
Bay on which they could be_ landed.
The questionis now under consideration,
and efforts will be made to settle it as
soon as possible.
The second is to exclude entirely all
shipments containing infected animals.
This action is not absolutely essential
now, as cattle can be landed under cer-
tain restrictions and immediately slaugh-
tered without spreading diseases, but
the exclusion of infected shipments
would deter importers from buying
cattle at infected ports, and place a
premium on importations free from the
diseases which we have been fighting
so many years. A shipment from an
infected port, found to be free from
disease on arrival and permitted to land
is much more dangerous in spreading
disease than the infected shipment land-
ed for immediate slaughter only. The
one is alive and in contact with native
cattle, to which disease will spread if
it develops, while the other is dead and
beyond the possibility of spreading
disease.
The next will be the complete exclu-
sion of allanimals from ports or places
known to be infected. While this step
is not justified at the present time,
it will ultimately prove an absolute
necessity. It can be done just as soon
as it becomes ceitain that an abun-
dant supply of cattle and carabao, to
meet al) our demands. can be had from
ports which are known to be free from
diseases, and from which infected ship-
ments will never come. The only sate
course is to make sure that the animals
of these Islands will have no chance to
become infected, and the only certain
way of guaranteeing them against
the further invasion of infective animal
diseases is to completely exclude all
animals from all ports and countries in
which infective diseases exist or are
liable to prevail.
CORNS ON HORSES’ FEET.
(From the Agricultural News, Vol.
VIII., No. 179, March 6, 1909.)
A corn on the foot of a horse or a
mule necessarily results in a certain
degree of temporary lameness. If the
proper method of treatment is adopted,
however, the trouble can usually be got
rid of in a comparatively short time,
but it is important to remember that
unskillful or ignorant treatment may
readily increase the trouble so as to
result in more serious lameness. The
following sensible note on this subject
is extracted from Hunting’s ‘Art of
Horse-shoeing ’ :—
A corn, be it remembered, is not a
tumour or a growth; it is merely a bruise
of the sensitive foot under the horn of
the sole. It showsitself by staining the
horn red, just asa bruise of the human
body shows a staining of the skin above
it. To ‘eut out acorn’ with the idea of
removing it issimply an ignorant pro-
ceeding.
If a corn be slight, all that is necessary
is to take off the pressure of the shoe,
and this is assisted by removing a thin
slice or two of horn at the part. When
the injury is very great, matter may be
formed under the horn, and, of course,
must be let out by removal of the horn
over it. Provided there is no reason to
believe that matter has formed, a corn—
1.@., the bruised and discoloured horn—
should not be dug out in the ruthless
manner so commonly adopted. Cutting
away all the horn of the sole at the
heels leaves the wall without any sup-
port. When the shoe rests upon the
wall itis unable to sustian the weight
without yielding, and thus an additional
cause of irritation. and soreness is manu-
factured, The excessive paring of corns
is the chief reason of the difficulty of
getting permanently rid of them.
The simplest device for taking all ©
pressure of a cornis tocut off an inch
and a half of the inner heel of the shoe.
With the three-quarter shoe a horse will
soon go sound, and his foot will then
resume its healthy state. The saying
‘once acorn, always a corn’ is not true;
but it is true that a bruised heel is
tender and liable to bruise again, from
very slight unevenness of pressure, for
at least three months. All that is neces-
sary is care in fitting, and abstention
from removal of too much horn at the
part. Of course, when the degree of
lameness is such as to suggest that
matter is formed, the horn must be cut
away so as to afford an exit forit; but
the majority of corns are detected long
before the stage of suppuration has re-
sulted from a bruise.
DAIRY FARMING: WILL IT PAY
IN CEYLON?
By GEo. SCHRADER.
(From the Ceylon Independent, 14th
January, 1909.)
By dairy farming I donot mean the
manufacturing of butter and cheese,
but the supplying of pure rich milk to
large towns at a reasonable price.
Everybody living in towns knows how
[JUNE, 1909.
JUNE, 1909,]
almost impossible it is to get.a supply of
pure rich milk ata reasonable price -
owing to these difficulties the great pro-
ortion of the people, who would prefer
Fr esh milk, have to be satisfied with the
preserved tinned stuff. Is it possible to
supply the pure article so that the
suppliers and the supplied will both be
satisfied ? I maintain that it is possible
to supply pure rich milk at 15 cents per
bottle, at the same time yielding hand-
some profits and quick returns without
any great risk. The business man will
say—‘‘ This is all very fine! but I want
more tangible proof than this before I
embark my capital.” Quite right! the
object of this article is to prove this by
facts and figures. I may say that Iam
not convicting a theoretical story, but I
am applying my knowledge and per-
sonal experience gained elsewhere to
what canbe feasibly done in Ceylon,
A branch of the work of a large mixed
farm I was managing in Australia was
the supplying of milk to a town five
miles away ; the portion of the country
the farm was situated was not physi-
eally suitable for dairying as the average
rainfall was 14 inches per year, so that
every bit of the food of the cows had to
be grown under irrigation, which meant
the great expense of pumping water by
means of expensive machinery, ete. ; but
still handsome profits were the result. Jt
is a well-known fact among the farming
world that thereisno branch of agri-
culture that brings in better, safer and
quicker returns than dairy farming, 7.e.,
the supplying of fresh milk to towns.
Every other branch of farming is guided
by the market, the prices of grain
and fruit, rise and fall &e. ; while the
cultivation of even our coconut palm,
tea and rubber, etc., means the outlay
of alarge amount of capital and the
waiting for a good number of years for
the first returns, whereas with dairying
the price isa fixed price, and from the
day the milk supply starts, the income
starts. In Ceylon we have not the
adverse circumstances I had to contend
with, as most parts of the country havea
splendid raintall averaging from 60 to 90
inches—the best spots are available for
the pioneers to pick and choose; the
market is unlimitted, so there is no neces-
sity to go to the less favoured parts of
the Island. Suppose, for example, a com-
pany was started to supply Colombo with
pure rich milk at a reasonable price.
What eapital will it require? What
would be the working expenses ? What
would be the returns? What risk is
there, and how should the farm be
worked? I do notthink there is any
necessity of labouring the subject of a
market, as everybody knows that there

isat present an unlimited market for
pure rich milk at a fair price, 12.e., cents

This means 274 per cent. on the capital

In examining these figures it will be
found that I have provided liberally for
every contingency, but even supposing
the cows or theclearing of the land, etce.,
cost more than estimated, there is still
left Rs, 7,168 out of the capital to meet
any excess. The balance remaining
will be tor working expenses—there is
no necessity of any large reserve for
working expenses, as it isonly for the
first month money from the capital
willbe required for that purpose—the
monthly expenses will be Rs. 641°20,
while the monthly income will be
Rs. 1,620 for a month of thirty days. The
handsome interest of 274 per cent. on
the capital will no doubt be viewed with
some suspicion, as too good to believe and
impossible—examine and analyse the
figures how you like and as you like, and
you will come to the conclusion that it is
feasible. It must be remembered that I
have only taken the milk of thirty cows
while forty cows form the herd. I have
done so although in the actual working
more than thirty cows will be milked
daily for the 365 days of the year ; stillit
must be remembered that cows require
two months’ rest before they calve for
the second milking, and also to allow
for any deaths and for any cows
that donot come up to the standard
of two gallons of milk per day; also for
the milk required to feed the young
calves for the first three months of their
life. Some might say that it is impos-
sible to get two gallons of milk per day
from a cow. I say from personal ex-
perience and knowledge that it is pos-
sible, it can be got, and it must be got,
and that every cow that does not come
up to that standard must be got rid of,
and the sooner the better.
(JUNE, 1909.
There is another very valuable source of
income that must not be forgotten. You
will notice that I have valued twenty-
five calves at Rs. 20 each, that is not
to say that they must be Sold for that
sum, and that the very ‘ow average
of twenty-five that I have put down for
safe calculation is to be the actual re-
sults of the farm. In three years’ time
there will bea splendid lot of young bulls
and cows for sale, after reserving for
the requirements of the farm, Sup-
pose at the end of the first:three years
we sold twenty-five head at Rs. 200, that
would be Rs. 5,000,so0 that the yearly
profits after the first three years will
always be increased by the sale of sur-
plus cattle.
There is another source of profit that
is worthy of attention, that of specialis
ing to supply milk from special cows
for the feeding of infants; for this pur-
pose the milk can be supplied in special
sealed bottles for 20 cents per bottle.
For the successful working of this or
any enterprise no source of profit ever
so small must be thought too much
trouble or not worthy of attention.
The questionjof risk is a very important
- one for the capitalist who embarks his
money. The land-will not depreciate in
value but will rather increase with the
improvements, etc. The imported cows ©
(as they must be imported from Austra-
lia) will stand the climate, especially if
they are secured from’ semi-tropical
regions ; we know that the Australian
horses and the dairy cattle now in the
Island are doing well. There is an
unlimited market in Colombo for pure
milk, especially at the price of 15 cents
per bottle. The food can be easily grown
if the manager understands his work.
Cattle diseases—there should be no
risk from any infectious diseases if the
farm is scientifically managed, as danger
from this source is generally due to bad,
careless and unskilled management.
How IS THE FARM TO BE WORKED.
The allimportant question—as an accu-
mulation of the best cows, the best land,
the best utensils and implements, ete.,
will not produce the supply of lactic fluid
that will be necessary to make the farm
pay—is the management of the Farm:
it must be properly worked by a capable
man. It must be remembered that dairy
farming isa science that requires deep
study and plenty of experience—on the
choice of the man who isto manage the
farm entirely depends the success or
failure of the undertaking. The people of
Ceylon have not yet reached that point
of understanding that Agriculture and
planting industries require the services
of qualified experienced men to get the
JunR, 1909. } 5
best results. No man will dream of
sending a clerk to take charge and work
an engineering establishment, but at the
same time he won’t think twice of send-
ing the same clerk to manage a dairy
farm, for he will argue—what is there to
be done—its an easy life—only to see
that che cows are milked, and to grow
some grass for them and to see that the
coolies give them food, and to get on to
his lounger and smoke and read novels!
That is all no doubt the clerk is capable
of doing, but let us see what the duties
are of the manager and what sort of an
education and experience is necessary.
“To see that the cows are properly
milked,” the manager must be a properly
trained and able milk man. (I wonder
how many of those that are in charge
of the present existing dairies know how
to milk a cow or have ever tried.) To
give the reason for this I cannot do better
than quote from my notes on lectures on
dairying that I received at the Aus-
tralian Agricultural College I attended.
Milking :—Itis of the greatest impor-
tance that the introduction of bacteria
into the milk should be prevented, and
therefore the utmost cleanliness from
the time the milker starts his work until
the finish is absolutely essential if the
best results are to be obtained. Before
milking the hands should be thoroughly
washed, also the cow’s belly, teats and
udder if they are dirty ;in any case the
dust should be brushed off them betore
milking, orsome of it, with the always
present bacteria, wil) be shaken off into
the milk. The finger nails should be
kept cut, and on no account should the
hands be wetted by first milking into
them—itisa dirty and useless habit.
The cow-yard should be kept clean, it
should not be cleaned just before milk-
ing; or bacteria will find their way into
the milk, to develop init flavours which
may not be at all desirable. Milk should
for this reason be taken from the cow-
yard immediately. The teats diagonally
opposite each other should be milked
together, and not the teats on each side,
as the former method increases the
quantity of milk. The milking should
be fairly fast as this increases the
secretion, whereas slow milking reduces
the quantity. The cow should be well
stripped, as the last striplings are rich
in fat; if any milk is left it is harmful to
the supply. If the teats are sore, they
should be handled with care, and after
milking should be dressed with vaseline,
ete., ete., ete.” A good milkman is able
to milk ten average cows per hour.
And to grow the grass for them? It
is not such an easy matter as the indi-
vidual who employed the clerk as
manager thinks it is, The manager must
Live Stock,
understand the science and practice of
preparing land and sowing the seed to
procure a sufficient supply of grass or
green fodder, or both, to feed forty-eight
head of cows, bulls, and horses and also
anumber of calves; he must know the
number of tons of green fodder neces-
sary, and how many acres will have to
be cultivated to grow that number of
tons. He must know to make the all-
important ersilage, and the number of
tons of ensilage necessary for feeding
the cows during the dry months, and
the number of acres that must be culti-
vated to grow that number of tons of
silage. No guess work will answer, as on
the quality and quantity of the _ best-
food depends the supply of milk. The
manager must understand the science
of feeding cows, as on it to a large
extent depends the success of the under-
taking, He must have some knowledge
of veterinary science, as it would be out
of the question and absurd to eall in a
veterinary surgeon except in the case of
any serious disorders. In fact, the
manager must bea qualified and expe-
rienced agriculturist and dairy farmer,
if the dairy farm is to be a success.
THe LAND.—The eighty acres of land
that I estimated for must be procured out
of Colombo but within a reasonable dis-
tance of the city, t.e., within five to
eight miles—the land must be carefully
chosen as for situation, soil, and a plen-
tiful and good supply of water. The
entire eighty acres must be cleared, the
stumps extracted, and fenced with a
plain wire fence, passing the wires
through holes bored in the posts, one
barbed wire being nailed right on the
top of the posts to prevent any jumping,
it must be again sub-divided into four
paddocks by means of more wire fencing,
so that each paddock will be 20 acres in
extent.
TATA SERICULTURE
BANGALORE,
FARM AT
By J. MOLLISON, M.R.A.C,,
Inspector General of Agriculture in India
—_—_— __
(From _ the Agricultural Journal of
India, Vol. IV., Pt. I., January, 1909.)
The late Mr. J. N. Tata established at
Bangalore a small Sericulture Farm
about 1898. It was started to help native
rearers to control such diseases as affect
silk-worms in India, and generally to
give technical instruction in growing
suitable kinds of mulberries, in rearing
Live Stock.
silk-worms, in reeling silk and preparing
it for market. The little farm has
answered these purposes admirably.
Mr. Tata was familiar with Japanese
methods. He considered them well suit-
ed to India. He got for the supervision
of his farm one Japanese Expert of the
artisan class and another who knew
sufficient English to act as interpreter.
The fittings and reeling machinery for
this small factory were mostly imported
trom Japan. They are simple, durable,
inexpensive and efficient. They were
put up by the Japanese Artisan Expert
elped by an Indian mistri and coolies.
The Japanese Expert and his wife trained
native girls of 10 to 14 years of age
to do the reeling. I have repeatedly
seen these girls at this work. The work
was excellently done.
I compare in the accompanying tabu-
lated statement this work as done bya
fieldman of my office after three months’
training at Bangalore, and the work
done by the most expert reeler in the
factory—a young girl.

The motive power for reeling and re-
reeling by 12 operators was done easily
by a woman slowly working a wooden
lever, and this power could have easily
done much more work. The 12 girls
could, ina day, reel and re-reel about
2 lbs. silk, which was worthat the time
of my last visit 17s. 6d. per pound in
England. The value of the refuse silk
was a considerable additional item of
income, but was not estimated.
The work of mulberry cultivation,
rearing silk-worms, improving varieties
of silk-worms by cross-breeding, detect-
ing diseases by means of the microscope,
preserving cocoons for seed and for
558 ate [Junn, 1909. _
hanking, pressing and packiug the silk
for market, was thoroughly done. Ap-
prentices were taken in free for instruc-
tion. A three months’ course was re-
quired for this purpose.
Bush mulberries only were grown.
The rainfall, average temperature and
soil at Bangalore and generally through-
out the Mysore plateau, appear to be
well suited for the cultivation of bush
mulberries. Those grown were three
grafted Japanese varieties, one Italian
variety and four others, probably
Indian. The Japanese varieties cannot
be propagated from cuttings; the others
can, Plants of the Japanese varieties
and cuttings of the other varieties can,
I understand, be supplied to those in-
terested in sericulture.
The soil of the garden isa good deep
dark red loam. Cuttings are first put in
a nursery, and when they have rooted,
are planted out 5 to 6 feet apart in
each direction. In order to maintain a
succession of young leaves throughout
the year, the various plots are pruned
in regular succession and irrigation
given when required. Crude sewage
and night-soil are used as manure with
excellent results.
Young leaves are required for the .
larvee when newly hatched. If there is
a fullsupply of these and of more mature
leaves when the worms are larger, six
or seven broods are reared in 12 months,
Disease prevails extensively in Mysore.
The following results were obtained
from seed cocvons obtained locally :—
(1) 615 moths laid eggs.
(2) 114 of these moths were diseased as
determined by miscroscopical ex-
amination; therefore the eggs
were destroyed.
(8) The larvee from 501 batches of eggs
hatched out.
(4) These silk-worms ate 38,566 lbs. of
green leaves. ,
(5) The leaves were obtained from 2°41 |
acres of bush mulberry in full
vigour of growth.
(6) 270 lbs, of cocoons were obtained.
At Bangalore, bush mulberry plan
tations get worn out even with care
ful pruning and cultivation in a few
years. Young plantations to replace old
should, therefoie, be formed from time
to time. Rotaticn is desirable, A ten-
acre area should prckably have 5 acres

other crops. The whole should yield
leaves sufficient for 6 or 7 broods in a
year, each as large as that referred to
above or larger.
‘Mr. Tata’s Expert recomiuends that
the rearing house should be separate
and at a distance from the buildings re-
quired for storing cocoons and reeling
with the object of avoiding the risk of
communicating diseases. The rearing
building should be constructed so that
light and ventilation are fully secured ;
a thatched roof and a verandah being
desirable to keep the day and night
temperatures fairly equable.
Expensive construction is unnecessary.
A mud floor does very well. There should
be a plinth and, exclusive of verandah,
a building 20ft. by 16 ft. is sufficient.
The height to eaves should bel0 ft. The
north verandah should be about 10 ft.
wide and enclosed to form a room, If
well lighted, the moths, as soon as they
have laid their eggs, should be examined
for disease under the microscope in this
room, which should have no direct con-
nection with the rearing house. The
healthy eggs only should be kept.
In the rearing house there should be
three wooden stands each 5 feet high,
3 feet wide, each with three shelves, the
lowest shelf should be 18 inches from the
floor, These stands should be so placed
that there is easy access to each. They
are required to support the trays in
which the silk-worms are fed. A brood
from 600 batches of eggs can be ac-
commodated in one tray when first
hatched out, but requires about 150 trays
when fully grown.

rearing house is :—

The reeling factory should be 90 ft, by

tion the basins and reels should be
ranged longitudinally ; on the other side,
the silk should be tested and re-reeled

be worked in the boiler house and also
one blacksmith and carpentry work
done.
The whole building should be con-
structed on a plinth with brick walls,
10 ft. high to eaves, with tiled roof.
The reeling room should have a paved
floor and arrangements for drainage, :
Mud floors are suitable for the other
rooms.
The office will require ordinary furnish-
ings with a vermin proof cupboard for
storing seed cocoons. The furnishings
are estimated to cost Rs. 50. The store
for cocoons should have a large central

INDIAN WILD-FOWL.
Tu INDIAN DucKS AND THEIR ALLIES.
By EK. C. Stuart BAKER.
(Review from Nature, January, 1909.)
The enormous flocks in which many
members of the duck tribe visit the
plains of India during the cold season,
coupled with the relatively large num-
ber of species by which the group is
there represented, affords ample justi-
fication for the issue of this handsome
and superbly illustrated volume. For
the swarms of ducks, geese, swans, and
mergansers naturally attract the atten-
tion of a host of sportsmen, many of
whom are anxious to identify the species
of the birds which go to form their bag,
and ascertain something about their
natural history. « Neither is the book of
less importance to the ornithologist—
either professional or amateur—for Mr.
Stuart Baker has much new matter to
record concerning many of the species
passed under view, while the thirty
coloured plates—reproduced from sket-
ches by Messrs. Cronvold, Lodge, and
Keulemans—have a distinct scientific
value of their own, altogether apart
from their beauty as works of art.
The origin of the book dates from 1896,
when the author was asked to communi-
cate a series of illustrated articles on
Indian ducks to the Journal of the
Bombay Natural History Society which
should incorporate the numerous notes
on the group published in the Indian
scientific journals and sporting papers
since the issue of Hume and Marshall’s
well-known ‘“Game-birds of India.”
These articles were commenced in the
eleventh volume of the aforesaid serial,
and the work now before us is a reprint
of the series with such additions and
emendations as were necessary to bring
them up to date.
560
[Junn, 1909,
Apart from the flamingoes, which are
brigaded with the ducks under the
general title of ‘‘Chenomorphe,” the
author recognises no fewer than forty-
three representatives of the group as
visiting or permanently residing in India.
He is, however, somewhat of a‘‘split-
ter,” and certain of his species, asin the
goose-section, would very probably be
relegated to a lower grade by many
naturalists. We are also ‘inclined to
disagree with his views as to the multi-
plication of generic groups. The divi-
sion of the flamingoes into two genera,
and likewise the splitting of the brent-
geese into Rufibrenta and Branta, are
examples of what appears to us totally
unnecessary complication in this matter.
The author has, however, taken Count
Salvadore’s British Museum catalogue
of the group as his guide, and he has
adhered religiously to the classification
therein adopted. We confess to a feel-
ing that it would have been better to
follow the late Dr. Blanford’s volume
in the ‘Fauna of British India,”
whereby greater simplicity would have
been secured and at the same time
some advance made towards uniformity
in the names of Indian animals. In this
connection we may note the urgent need
of a proper table of contents at the com-
mencement of the volume, the one which .
does duty therefor being too absurd for
words, two out of its half-dozen items
being ‘‘ title-page” and ‘‘ contents,” while
a third is “ Indian Ducks.”
For a book which must be largely
patronized by sportsmen (ifit is to make
a profit), we also venture to think that
too many technical terms, or definitions,
are introduced without any sort of
explanation. What, for instance, will
the sportsman (or, for that matter, the
amateur naturalist) make of the bald
statement that the Chenomorphx are
characterised by having the ‘palate
desmognathous,” or what will he under-
stand by the ‘‘neotropical region”? If
such expressions are used at all, they
ought to be adequately explained, but in
our opinionthey are altogether out of
place in a work of this nature, the pro-
fessional naturalist does not want them,
and the amateur and the sportsman do
not understand them. In the place of
the former a statement to the effect
that the palate in the dry skull is of the
closed or bridged type, and that the
difference between the bridged and the
open or slit type may be realised by
comparing the skull of a duck with that
of a fowl, would have been much more
to the point, while as regards the latter
it would have been infinitely better to
use the ordinary names, South and
Central America, in place of neotropical —
region,

With these exceptions—if it be added
that the author has an extremely old-
fashioned: and obsolete way of spelling
Indian place-names—we have nothing
but commendation for the volume before
us, the species being clearly and care-
fully described, with full and _ well-
written notices of their distribution and
habits. As Mr. Baker observes, the
collection and collation of a vast amount

of seattered information concerning the

information on the subject, and to

should be taken into camp in each

SCIENTIFIC AGRICULTURE.
THE CONSERVATION OF SOIL
MOISTURE AND ECONOMY IN
THE USE OF IRRIGATION
WATER.
By EH. W,. HILGARD AND R. H.
LOUGHBRIDGE.
(From the University of California
Agricultural Hauperiment Station
Bulletin 121.)
(Continued from pp. 456,)
Basin Irrigation.—It will be noticed
that this principle is practically the
same as that of the basin irrigation of
orchards, which was originally largely
practised in California, but has now
been mostly abandoned for furrow irri-
gation. The latter has been almost
universally adopted, partly because it
requires a great deal less hand-labour,
partly under the impression that the
whole of the soil of the orchard is thus
most thoroughly utilized; partly also
because of the injuriovs effect upon
trees produced at times by basin irri-
gation.
The explanation of such injurious
effects is, essentially, that cold irrigation
water depresses too much the temper-
ature of the earth immediately around
the roots, and thus hinders active vege-
tation to an injurious extent, sometimes
so as to bring about the dropping of the
fruit. This, of course, is a very serious
- objection, to obviate which it might be
necessary to reservoir the water so as to
allow it to warm before being applied to
the trees. In furrow irrigation the
amount of soil soaked with the water
is so great that the latter is soon effec-
tually warmed up, besides not coming
in contact too intimately with the main
roots of the tree, along which the water
soaks very readily when applied to the
trunk, thus affecting their temperature
much more directly, Itis for the fruit-
-grower to determine which consider-
ation should prevailin a given case.
71
the water-supply be scant and warm,
the most effectual use that can be made
of it is toapply it immediately around
the trunk of the tree, in a_ circular
trench dug for the purpose. When, on
the contrary, irrigation water is abun-
dant and its temperature low, it. will be
preferable to practise turrow irrigation,
or pessibly even flooding. As to the
more complete use of the soil under the
latter two methods, it must be remem-
bered that while this is the case in a
horizontal direction, yet unless irriga-
tion is practised rather sparingly under
the furrow system, it may easily happen
that the gain made horizontally is more
than offset by a corresponding loss in
the vertical penetration of the root-sys-
tem. This is amply apparent in some of
the irrigated orange groves of Southern
California, where the fine roots of
the trees fill the surface soil as do the
roots of maize in a corn field of the
Mississippi States ; so that the plough can
hardly be run without turning them up
and under. In these same orchards it
will be observed, in digging down, that
at a depth of afew feet the soil is too
water-soaked to permit of the proper
exercise of the root functions, and that
the roots existing there are either in-
active or diseased. ‘That in such cases
abundant irrigation and abundant ferti-
lization alone can maintain an orchard
in bearing condition is a matter of
course; and there can be no question
that a great deal of the constant ery for
the fertilization of orchards in the
irrigated sections is due quite as much
to the shallowness of rooting induced by
over irrigation, as to any really neces-
sary exhaustion of the land. When the
roots are induced to come to and remain
at the surface, within a surface layer
of eighteen to twenty inches, it natur-
ally becomes necessary to feed these
roots abundantly, both with moisture
and with plant food. This has natur-
ally led to an over-estimate of the
requirements of the trees in both
respects. Had deep rooting been en-
couraged at first, instead of over-stimu-
lating the growth by surface fertiliza -

tion and frequent irrigation, some delay
ic bearing would ,have been amply
compensated for by loss of current
outlay for fertilizers, and less liability
to injury from frequently unavoidable
delay, or from inadequacy of irrigation.
Conservation of Soil Moisture. —Along-
side of economy in the use of irrigation
water, the conservation of the moisture
imparted to the soil either by rains or
irrigation ismost important; critically
so where irrigation is unavailable.
Utilization of Winter Rains and
Winter Irrigation.—However strong is
the popular demand for storage of the
winter rainfall and flood waters, too
many do not appreciate the importance
of the storage they can command with-
out the use of reservoirs within their
own soil mass. While there is a well-
grounded objection to subjecting plough-
ed land to the leaching action of the
abundant raius in the humid region, no
such objections hold in the case of
lands lying within the limits of 20 to
25 inches of annual rainfall. Here the
absorption of the winter rains should be
favoured to the utmost, for the run-off
is mostly a dead loss. Fall ploughing
wherever the land is not naturally
adequately absorbent, and is not there-
by rendered liable to washing away, isa
very effectual mode of utilizing the
winter’s moisture to the utmost, so as to
bring about the junction of the season’s
moisture with that of the previous
season, which is generally considered as
being a condition precedent for crop
production in dry years. The same of
course holds true of winter irrigation;
the frequent omission of which in
presence of a plentiful water supply at
that season isa prolific cause of avoid-
able crop failures. Moistening the ground
to a considerable depth by winter irri-
gation is a very effective mode of pro-
moting deep rooting, and will thus stand
in lieu of later irrigations, which being’
more scant, tend to keep the roots near
the surface.
Knowledge of the Subsoil._It caunot
be too strongly insisted upon that in
our arid climate farmers should make
themselves most thoroughly acquainted
with their subsoil down the depth of
at least four, but preferably six or
eight feet, This knowledge, import-
ant enough in the Hast, is doubly
so here, since all root functions are and
must be carried on at much greater
depths. It is hardly excusable that a
business man calling himself a farmer
should omit the most elementary pre-
caution of examining his subsoil before
planting orchard or vineyard, and
should at the end of five years find his
trees a dead loss in consequence of an
562
unsuitable subsoil. Similarly, no irri-
gator should be ignorant of the time
or amount of water it takes to wet
his soil to a certain depth. We have
lately seen a whole community suffering
from the visible decline of thift of its
fruit trees, which occurred despite what
was considered abundant irrigation;
a.e., allowing the water to run for a
given length of time, deemed to be suffi-
cient. Yet on being called in to investi-
gate the causes of the trouble, the
station staff found that the irrigation
water had failed to penetrate during
the allotted time to any beneficial
extent, so that the trees were, in the
main, suffering from lack of wmois-
ture—a fact that could have been
verified by any one of the owners con-
cerned, by simply boring or digging a
hols or two. But no one had thought
of doing so, and all kinds of myste-
rious causes were conjectured to be at
work in the suffering orchards. of oo bal Ae 5 a5,

This year the experiments were carried
out with Wheat and Barley. The final
ploughing and working of the land was
commenced on the 15th July, 1908, and
completed on the 16th July, 1908. The
seed was sown with the Superior Drill,
viz :—
Wheat at the rate of 60 lbs. per acre.

The normal dressing ot 200 lbs, of
complete fertiliser per acre was applied
to the whole area. lLadybirds were
again very troublesome, damaging the
barley: to a great extent, but as the crop
was affected in like degree throughout,
this did not interfere with the experi-
ment, except that the yields throughout
were far below normal :—

Here again the cost of the first plough-
ing was taken at 6s. per acre and the
cost of each additional cultivation at 1s.,
and, as can be seen by the table, a fair
profit was 1eceived for each additional
cultivation.
The cost of ploughing three or four
times, such as was tried with the oat ex-
periment of 1907, was found very costly,
when by working the land with a culti-
vator good results were obtained at one-
sixth the cost, and, of course, the time
saved by using the cultivator instead of
the plough is enormous.

AGRICULTURAL COLLEGE
COIMBATORE.
By C. J. W. SHEPPERSON,
Principal of the Agricultural College,
Coimbatore.
(From the Madras Agricultural
Calendar, 1909.)
This College is situated in the village
of Thelungapalaiyam, about three miles
west of the town of Coimbatore. The
estate consists of 450 acres of land, of
which 50 acres are good single crop wet
lands, of the remainder about 3800 acres
are available for cultivation, the rest
being occupied with buildings and the
compounds attached thereto. The dry
lands are of various kinds, about 126
acres being black cotton soil of, how-
ever, varying qualities. The red lands
likewise vary from sandy to stiff clay
loams. On the red lands there are ten
wells which command most of the area,
but there is a considerable area of unirri-
gable land. It will be seen, therefore,
that the lands are suitable for various
crops and methods of cultivation.
The institution is more or less divided
into two sections, one devoted to the
study of problems in Chemistry and
Biology which arise in connection with
Agriculture, and the other devoted to
giving asound knowledge of the sciences
upon which the Art of Agricultureis
-

based, and of the principles which
should govern any attempts to improve
indigenous methods. Provision is made
for the entry every year of twenty stu-
dents, thus, usually, the students will be
divided into three classes according to
their year.
The main building contains the neces-
sary accommodation for the work of
the Government Botanist and Agricul-
tural Chemist, as well as class-rooms and
laboratories for the instruction of the
studentsin Chemistry, Biology, Physics,
Agricultural Engineering, and _ the
principles of Agriculture together with
a library and reading-room for their use.
The students will undergo instruction
not only theoretical but also prac-
tical in all the subjects of the course
which includes a certain amount of
Veterinary science sufficient for the
treatment of ordinary cattle ailments.
In Agriculture they will take part in all
the ordinary farm operations such as
ploughing, sowing, weeding, ete., and
in their second and third years will
each cultivate a plot of land themselves.
It must be borne in mind, however,
that agricultural practice is very
largely determined by climatic condi-
tions, therefore the practical agricul-
ture followed will be that suited to
Coimbatore, and operations carried
out ina certain way at Coimbatore
may require a considerable modifica-
tion if introduced into another district.
The object of the introduction given in
the college is to enable men who
have profited by it, to so modify their
practices as to suit the conditions
of any region to which they may go; in
short, it should enable them to think
out their own particular difficulties.
The character of the soil again deter-
mines very largely thekinds of imple-
- ment which can be advantageously used,
and during their course at the college
students will have the opportunity of
working, and of seeing worked, various
implements designed to do certain work
either more quickly or more efficiently
than those in use at present, but they
will not be expected to believe. that
because an implement is either a success
or a failure here, it must necessarily
be soon their own lands; they must
be prepared to make the experiments
themselves if they see it is likely to
succeed, and they should be enabled to
suggest and put into practice modifica-
tions which will render the implement
suitable to their own conditions in case
it is a failure.
The college session begins on or about
June 7th and ends on March 3lst. There
are three terms ending respectively on

or about September 30th (Dasara) ;
December 20th (Christmas); and March
3lst. At present no fees are charged,
but students provide their own board
and cook. There are hostels attached
to the college for the accommodation
of students, arranged in blocks of six,
each block having a separate kitchen and
dinning-room, thus, ‘students of differ-
ent castes can be provided for. It will
be found most economical for all the
students of any one caste to join to-
gether and have acook incommon. The
cost of living will, of course, vary with
the different tastes of different students
and with the price of food-grains ; it may,
however, be taken as being about Rs. 10
per month for vegetarians, An Athletic
Club is attached to the college to which
all students must belong. The sub-
scription has been fixed at the lowest
possible, viz., 4 annas per month. A
reading-room has also been started by
the students themselves for the purchase
of papers, etc., to which the subscrip-
tion has been fixed by the members at
4 annas per month.
The question may arise: what is the
use of attending the college, and what
are the prospects of men who have
passed through the course? To these
questions it may be answered (1) as to
prospects. Those who enquire about the
prospects are, generally speaking, those
who have not enough land themselves
to enable them to make a sufficient
living, and for such there are various
Openings as managers of farms under
zaminders and other large proprietors,
and alarge farm like any other business
always pays for good management.
Several enquiries for men capable of
managing such farms have been received
at the college during the past year.
As, however, the college is established
for the benefit of Indian Agriculture,
it is supposed that students will join in
order to obtain knowledge to improve
the yield of their own lands, and not
merely in order to qualify for a post
under Government ora zaminder. This
leads to the answer to the other half of
the question as tothe use of attending.
In every large business, manufacturing
or otherwise, there are usuaily two
classes of men: the workers or labourers
and the foremen or managers. The
first of these classes is required to do
the heavy and more or less mechanical
work ; they arein many cases not requir-
ed to be men of any_great mental capa-
eity. The second class is composed of
men who have brains and know how to
use them for the benefit of the business,
they guide the energies of the workers
in the path which will lead to the best
results, Itisthe latter class that wil

gain most benefit in attending the
Agricultural College, In too many
instances an owner of a small area
contents himself with letting his land to
a cultivator, often of inferior mental
capacity, and with receiving a share of
the produce at harvest; whereas, if he
used his superior brain power in direct-
ing his labourers, he would very pro-
bably obtain a larger return from the
land.
HEREDITY.
By R. H. Lock. &
The children of men are like their
parents ;soare the children of animals
and plants. The time is not so very
remote when this was the sole definition
which could be given to the term here-
dity ;and information as tothe nature
of this mysterious process was neither
sought nor found.
Simple as the above statement may
seem, there is yet a valuable truth
embodied in it. Our ancestors were
endowed with powers of belief which
enabled them to accept as true the
most exaggerated assertions with regard
to unlikeness between parents and their
children. Among other remarkable
manifestations of faith they believed
that an animal might be the offspring
of a plant or vice versa, as in the case of
the celebrated barnacle goose. This
was a tree described and illustrated by a
famous savant of the Renaissance. The
fruits of the tree were barnacles, and
when ripe they opened and from eacha
young bird emerged. The tree grew by
the margin of the sea, greatly to the
convenience of the geese, which fell
immediately into the water and swam
merrily away-
Such a method of generation, if it
were actually to occur, would offer a
notable exception to the ordinary course
of heredity. Every rule has its excep-
tions, however, and it does not become
an honestly inquiring mind to deny the
possibility of even so remarkable an
occurrence as the birth of the barnacle
goose. Still anyone with a competent
knowledge of the comparative structures
of a goose, a tree, anda barnacle would
require, like Huxley, considerable evi-
dence before accepting the statement
thata bird actually came into being
in this way. The actual amount of
evidence which would be required is a
little difficult to estimate. No sane man
would nowadays accept the evidence of
his own eyes in sucha case; nor would
the testimony of twelve good men and
true approach the required standard of
verification.

~
A universal belief, however exag-
gerated, has very often some grain of
truth concealed init, and.we may seek
the kernel of these extraordinary stories
in the fact that the children, whether of
men or of plants, are never exactly like
their parents. In some cases indeed
they are very different, though usually
partaking of the racialor specific type
to which the parent belongs.
The fact that a man has two separate
parents who are not identical effectually
disposes of any possibility of his exactly
resembling both of them. He might
indeed exactly resemble his father, but
itis a matter of common experience
that fathers and sons are always distin-
guishable. Most people on the other
hand show some points of resemblance
to both their parents. A _ child may
have its mother’s eyes, and may take
after its father in the colour or texture
of its hair, whilst its nose may be the
very image of that to be seen in a family
portrait of its great-grandfather. If we
reflect upon the details of any particular
case, -we shall very soon realise how
great a number of separate points go to
make up the complete hereditary endow-
ment of the individual.
When we thus remember the great
number of separate features of resem- -
blance to one parent or the other which
may be exhibited in any particular case,
we seeat once the great inconvenience
of treating individual people as units in
heredity. Butitisonly quite recently
that anyone has ventured to adopt a
different method. The new method
consists in regarding the individual
animal or plantas being builtup of a
number of separate factors, comparable
with the different kinds of stones with ~
which a house may be constructed.
These factors correspond in a general
way with the various features and
characteristics of the creature, and they
are inherited quite independently of
one another. :
The first point, then, which is to be
emphasised in any account of modern
ideas about heredity is that which con-
cerns the existence of unit characters.
It is no mere metaphor when we speak
of the separate attributes of an organism.
But itis quite a recent discovery that
we can in effect take an animal or plant
to pieces and deal separately with the
inheritance of its separate parts.
which are separately inherited so much
as certain definite attributes or charac--
teristics of these. Thus to take an ex-
ample, in the case of the domestic guinea-
pig, @ kind of animal in which heredity
has already been some what fully studied,
the sort of characters which can be

dealt with separately are the colour of
the fur, whether black, brown, or white ;
and the distribution of these colours,
whether uniform or in patches; the
nature of the hair, whether long or
short, and its quality whether smooth
or curly. We have here no less than
five pairs of attributes all characteristic
of a single organ, namely the fur of the
guinea-pig; these attributes being: (1)
the presence or absence of a_ black
pigment ; (2) the presence or absence of
a brown pigment—in the absence of both
these pigments the coat appears white—
(8) the distribution of these pigments,
whether uniform or not; (4) length or
shortness; and (5) curliness or smooth-
ness. Itis found that these attributes
may occur in all possible combinations
with one another—impossible combin-
ations being represented by the associ-
ation of two members of the same pair,
for instance the hair cannot be at the
same time black and white. But we
may have long curly black hair, or short
strait white hair, and many other combi-
nations. More than this, each of these
attributes is inherited perfectly inde-
pendently of all the others. The black-
ness may be derived from one parent, in
which the hair was perhaps short, and
length from the other parent the colour
of whose hair may have been white.
The fact that the phenomena of here-
dity have been found to be amenable to
definite experiment, depends entirely
upon the existence of definite unit charac-
ters such as these. The young guinea-
pig may take after one parent in colour
and after the other in the length of its
hair, whilst it may possibly exhibit a
third character, for instance curliness of
the hair, which was shown by neither of
its parents, but which was perhaps visi-
ble in one or more of its grandparents.
But we are already in a position to
speak much more definitely than this
concerning the precise manner of trans-
mission of unit characters from parents |
to offspring. Since every individual is
complete in itself, each parent must
eontribute to its offspring one complete
set of these factors. Every child, there-
fore, is provided with a doubie set of
factors, half derived from its father and
half from its mother; and every charac-
ter or feature which the child exhibits
depends upon the presence of a pair of
factors, one member of the pair being
paternal, and the other maternal, in
origin.
We might expect from this description
that every characteristic of the off-
spring would be simply the mean of the
corresponding characters of the two
parents, since the contribution of each
parent to that character is equal. But
72

Miscellaneous
this is not by any means always the case.
In some instances indeed the influence of
the two parental factors is about equal,
and asa result the offspring shows an
intermediate character. But in other
cases one factor may beso much stronger
than the other that the character of
one parent is almost exactly reproduced,
whilst that of the other remains entirely
in abeyance. In other cases again,
although one of the factors is stronger
than the other, the weaker factor is still
able to make its influence felt to some
extent.
In illustration we will consider a case
in which one factor is so powerful as to
render the other entirely invisible or
recessive. The case is that of a cross
between a black and a white strain of
mice. A pure black mouse is to be
mated with a pure white one. Into each
of the offspring arising from this mating
there enters something representing
blackness and something representing
whiteness. These representative some-
things we may distinguish as factors—
a black factor and a white one. It is
convenient to use black and white
draughtsmen as models with which to
follow the subsequent moves of these
factors.
Within a pure black strain, each of
the two parents of any individual con-
tributes a black factor to that indivi-
dual, and we may therefore represent
such an individual, in respect of the
character blackness, by two black
draughts. We thus indicate the essen-
tially double nature of all the higher
animals and plants, this double nature
being explained by the fact of their
having arisen from two separate parents.
In like manner, a member of a pure
white strain may be represented by two
white draughts, and the cross between
a pure black and a pure white strain
may be represented by one black and
one white draughtsman placed together.
In the yarticular instance which we
are considering the cross bred individual
appears black—in technical language
black is said to be dominant over white,
and white is said to be recessive. This
fact can be represented by placing tha
black draught on top of the white one;
but we must be careful to remember
that the white draughtis also present all
the time, only it is hidden ucderneath.
In the same way in the black cross-
bred mouse, the character whiteness
exists in a latent condition (better called
recessive), although to all appearances
the creature is pure black.
We now arrive at the crucial point of
the whole story. When the cross-bred
individual forms its reproductive cells,
—
Miscellaneous.
the behaviour of the black and white
factors is the simplest conceivable. We
have to picture the original black and
white-determining particles—whatever
their nature may be—to have multiplied
to such an extent that there is now a
pair—a black and a white—in every
one of the cells which build up the
organism. Each of these cells has been
produced by the division into two equal
parts of a previously existing cell, and
in all ordinary cases the black factor
(for example) divides into two before
the cell divides, and half passes into
each of the new cells formed, But in
the division which leads to the forma-
tion of the reproductive cells the factors
do not split. On the contrary the
black and the white factors separate
from one another. And every repro-
ductive cell which arises contains either
one or the other—a black or a white—
but never both together and never a
blend of the two. Thus if we pay atten-
tion simply to this pair of characters.
black and white, we can represent the
repoductive cells of the cross-bred indi-
vidual by any number of single black
and white draughts—an equal number
of each; for it appears that in both
sexes each of the two factors turns up
in very nearly the same number of repro-
ductive cells.
Now suppose a pair of these cross-bred
individuals to be mated together. The
essential process of such mating con-
sists, of course, in the union of a pair
of reproductive cells, one derived from
either parent. So far as we can tell
these reproductive cells will meet
entirely at random. It is like an
experiment in which one draws a single
draughtsman out of each of two bags,
supposing each bag to contain an equal
number of blacks and whites.
Thus we may draw :—
(1) A black from the first and a black from the second
(2) black op white a
(3) white * black ‘

known Russian Tea Merchant, Mr, Constantine
Popoff, really endeavours to make them do too
much, Mr. Popoff evidently wants to maintain
that the productiveness of his tea pJa:tatien in
the Caucasus has proved greater than v 1.0 pro-
ductiveness of tea plantations in Ceylon. He
takes the number of acres of tea planted and the
total quantity exported yoar by year for the
first 13 years of the existence of the Ceylon
tea industry ; and this he contrasts with the
first thirteen years of the working of his own
estates. Heo makes out that during tho period
Ceylon attained the maximum production of
14 lb. per acre, while on his plantation 146 lb.
per acre was attained. His tigures as regards
Ceylon merely represent the amount of tea ex-
ported and take no stock of the quantity
consumed locally ; but he does not point out
that, in the early years, there was of course no
tea in bearing. On the other hand he has been
able to account for every ounce of tea produced
on his own property. At the present moment
Ceylon is producing 460 1b per acre all round on

RUBBER IN THE PERUVIAN ANDES
AND AMAZON.
MR. J. B. CARRUTHERS EXTRAOTS
INFORMATION FROM A LECTURER,
A most interesting paper on ‘‘ The Resources
of the Peruvian Andes and Amazon,” by Mr.
C. Reginald Knock, F.r.¢s., Civil and Mining
Kagineosr, was read before an ordinary meeting
of the Society of Arts on April 28th. The paper
dealt mostly with the mineral wealth of these
countries, but rubber was frequently mentioned,
and at the close some further interesting infor-
mation was adduced in the course of discussion
by Mr. J. B. Carruthers among others. From
the lecturer's paper we extract the following :
There are gold mines ; untold wealth of silver ;
there is copper and coal and guicksilver in
abundance; and farther on yet there is wealth
of rubber and timber and chocolate and sugar.
cane, great herds of sheep and cattle and alpa.-
cas, and many other matters of satisfaction to
the traveller, the capitalist, and the merchant...
And far beyond tho great Cordilleras we shall
see canoe-loads of ‘tblack gold,” the rubber from
the forests, as the rubber-gatherer shoots down
the rapids of the Amazon affluents towards the
[quitos market. Tho wealth of an empire lies
within and beyond the Andes and upon the
Peruvian Amazon, waiting only the set of
humanity that way to gather it in for huma-
nity’s use.
Leaving the high regions of the Andes wa

Amazon plain. The natural resources of this
vast region might be summed up by saying that
it forms one of the world’s great natural store.

houses for the future. It is traversed by navi-
gable streams and rivers in great part; all
affluents of the Amazon. Of these waters 10,000
miles are navigable at all seasons of the vear for
steamers of varying draught, whilst in the wet
season tho total available navigable waters in
rivers and streams, for steamers, launches, and
canoes, exceeds 20,000 miles, all in Peruvian
territory.
The main product of this wild region at
present is rubber, of which the output is valued
at about 14 millions sterling per annum. In
the Peruvian montana there are very extensive
rubber- bearing forests, both in that part of the
Amazon plain drained by the affluents of the
Madre de Dios river, and, although less known
the region to the north drained by the Maranon
and Huallaga. The principal Peruvian rubber-
bearing trees are the Shiringa or Hevea, and
the Caucho. The Hevea is the superior kind,
and is that which has made Brazil famous as a
rubber producer, The tree requires a rich, deep
soil and abundant moisture, and at times grows
to great size. It lends itself to cultivation,
although not much has been done in Peru yet
in rubber-planting. Large areas of rubber-
bearing land have been taken up in Peru; prin-
cipally by Peruvians but partly by foreign com-
panies; though much land still remains un-
occupied,
Discussion.
Mr H Hamel Smith enquired about the nature
of the labour available, and whether any would
have to be imported, provided it was decided
to cultivate rubber in Peru. It would also be
of interest if informetion was forthcoming as
to whether the cost of the land would be an
important consideration in the question, and
whether the transport of the rubber when it
was grown would be a serious matter. Would
it be possible to bring the produce down to the
Pacific coast instead of, asat present, having to
make the long journey down the Amazon to the
Atlantic seaboard? Unless that were possible, it
wouldrender the profitable cultivation of rub-
ber in Peru quite hopeless compared with the
Federated Malay States and Ceylon, where the
costof transport was comparatively low. He
understood that therubber grown in Peru was
of excellent quality, asit wasin Bolivia, but the
danger and expense of cultivating it was very
great.
Miss Webster thought the value of the paper
would be increased if the author could givesome
particulars of the trees found in the forests.
Were there any timber trees ?
Mr J B Carruthers asked the author for in-
formation respecting the proportion of Para
rubber trees in the natural jungle region he had
described as rubber-producing, and what were
the possibilities of extracting the rubber from
them, apart altogether from the question of
planting rubber.
Mr Enock, in reply, said that labour in the
forest regions was rather scarce, and he believed
some of the rubber companies engaged there
had found that their main difficulty. Peru was
anxious to introduce Japanese labour, a good
deal of which was employed on the coast. The
natural outlet of the rubber region was down

the Amazon, because the rubber forests existed
on the tributaries of that river, It had, never-
theless, been found cheaper by some of the
companies working the rubber lands to bring
the rubber over the Andes and down the rail-
way to Mollendo. As soon as roads, perhaps
motor roads, and short lines of railways were
constructed on the natural outlet down the
Amazon, he thought, there would be an enor-
mous development of trade. The Amazon forests
possessed the peculiarity that they were unlike
the other forests of the world, which. consisted
very largely of one kind of tree. They consisted
of all kinds of trees, in fact, he believed it had
been calculated that in one square mile there
existed thonsands of different kinds of trees, and
this rendered the Amazon forests perhaps of less
value than some of the other forests of the
world. If a particular kind of tree was re-
quired, it was sometimes necessary to hunt
about for it a good deal. There were, however,
great groves of what was termed cedar there,
although it was not a true cedar; but it was a
valuable wood, Valuable hard woods also grew
in the forests. The question of the proportion
of rubber trees to other trees was hard to
answer. The rubber-bearing land was confined
to acertain zone of land upon the margin of the
rivers which were tributary to the Amazon ; but
it was impossible to state the exact proportion
it occupied of the total area.
CULTIVATION OF A SANDY SOIL.
Sandy soils are of various descriptions ran-
ging from those in which sand largely pre-
dominates to othera which are of a sandy
loam, and, in consequence, highly desir-
able for the production of potatoes and many
other crops. The disadvantages of a sandy
soil are that it is deficient in lime, in sub-
stance, and in vegetable matter, while it is
often so porous that it fails to retain moie-
ture during the growing season, when, how-
ever liberal the farmer may be in the provision
of manure, especially of artificials, he fails to
obtain a paying crop. It is extremely ditlicult
to cultivate with profit sandy soils of many
classes, for the simple reason that they are
so subject to suffer in a droughty season. It
is true that much is saved by the easo with
which they are cultivated with the plough
and other implements, while they can be
cleaned at much lower rate than land of a
more substantial character. An owner or at
occupier of a sandy soil, if it isnot toolight
in character and will pay. for extra cultiva-
tion, will be well advised to improve it by the
addition of clay or marl, and especially by
the cultivation of crops which are rich in
nitrogen for the purpose of ploughing in.
In Germany very large areas have been
improved so much: by persistent cultivation
that they have reached a substantial price, al-
though originally purchased at some 12s an acre.
Suppose that a commencement is to be made.
Something should be done in the way of mar-
ling, while potassic and phosphatic manures
may be supplied with some liberality for a
few years in succession in order to feed the
plants which are to be grown for ploughing
and Magazine of the Ceylon Agricultural Society.
in, Tho vetch might be taken as an example,
for by the aid of the mineral manures it would
be in a position to obtain its own nitrogen
from the air, especially if aided by the dril-
ling of some fertile soil with the seed, and
thus, when ploughed beneath, it would not
only provide a quantity of humus and make
the soil more substantial, but provide feed-
ing matter for the succeeding crops. There
is no likelihood of a loss of the potash or the
phosphates owing to heavy raiu, although,
under certain circumstan2es, a loss of nitrogen
might be sustained, A crop of vetches sown
in spring and ploughed beneath might be
followed by a crop of rape or rape and mus-
tard, either ploughed beneath, as in the case
of the vetches, or fed off by sheep receiving
artificial food. And so, from year to year
until a sufficient time has elapsed to induce
the grower to attempt a potato or a corn crop.
This he would do on ascale not too exter—

impossible to use dung, owing to the fact that
crops are not grown with which to produce
it. In course of tims—that time depending

tinue to plough alarge quantity of green forage
beneath the soil from year to year without
obtaining some tangible result. ‘The soil would
gradually accumulate fertilising matter in such
quantities that it would be able to grow good
crops of grain, roots, and potatoes, and, indeed,
ofa variety of other plants, and with these chiefly
consumed upon the farm, manure would be
made, and the larger the quantity the better for
distribution on the land. Thus, by the aid of
the dung of the farm, it would not be essential
to purchase so large a quantity of artificials.
Some years ago an agricultural scientist in
France made a number of experiments on a
somewhat extensive scale, with the object of
ascertaining how a soil should be composed in
order to produce the largest yield of the leading
crops grown by farmers. He found tiatif the
four typical varieties of soil, those chiefly com-
posed of clay, chalk, sand, and peat, were mixed
together in equal volumes, he obtained the best
results, Such a soil was mellow, easily worked,
rich in lime and humus, and capable of retain-
ing moisture in hot weather, while responding
well to artificials. There are, indeed, certain
varieties of plants with which the gardener is
better acquainted which require soils of differ-
ent types, but this fact can easily be verified by
any observant man who examines the weeds
which grow on every class of soil, He will, for
example, find the sandwort, the field madder,
the mugwort, and bent grass upon sandy soil ; on
chalk land he will find the spikenard, the yellow
hawksbeard, and the wooly thistle; and so, in wet
soils, in marshes, on gravels, and clays, different
varieties of plants are found which are seldom
seen in other places ; indeed, the weeds, like the
timber trees, indicate very closely the variety of
soil upon which they grow. The farmer, how-
ever, is compelled to adapt his crops to the soil

he farms, and itis for this reasou that he has
adopted certain methods which enable corn and
other crops to grow with freedom and success,
ff asoilis damp, he drains it; if it is tenacious
like a heavy clay, he endeavours to reduce its
tenacity and make it porous by the addition of
sand, lime, the ploughing in of green crops,
heavy dressings of farmyard manure, and plough-
ing ab particular seasons, when it falls to pieces
and provides a finer tilth. So itis with soil of a
sandy character, which fails to hold suftlicient
nioisture for the use of plants, which is but
slightly fertile, deficient in humus, lime and
such matorials as clay, which are best catculated
to make it more substantial and adapt it to
retain moisture and prevent the loss of nitrogen,
which is so easily carried through it by the rain.

THE TEA SEASON IN JAPAN.
The now tea season is about to setin. The
first shipment of new tea this year, says the
“Mainichi Dempo,” was made by the ‘‘Korea,”
which left Yokohama for San Francisco on April
24th. In anticipation of the rejection of
the proposed tea duty in America the Yokohama
and Shizuoka tea markets are now actively pre-
paring for the opening of tho season. This
year’s tea crop is not particularly different from
that of last year, but the state of the markets at
home and abroad seems to be very promising,
The amount of tea exported from Japan between
May, 1908, and April, 1909, was 32 million
pounds, showing a decrease of about two million
pounds as compared with the previous year, In
consequence stocks of last season tea in America
this year are not so heavy as in ordinary years,
while the remnants of old tea in Yokohama and
Shizuoka, which will be exported in the course
of the present month, do not exceed four million
pounds in quantity. Thus stocks of old tea are
comparatively low both at home and abroad,
Moreover, the conditions in America in respect
to the demand for tea are improved, the finan-
cial crisis of last year having nearly passed away,
On the other hand, the money market in Japan
is easy. The situation is, therefore, advanta-
geous for tea transactions at present. Accord-
ingly, tea merchants in Japan are more encour-
aged than in ordinary years, and itis believed
that the amount of exports will be largor than
last year, The standard price of new tea is ex-
pected to be somewhat lower thau the average
price last year (Y.24 or Y.25), Tho direct ex-
portation of tea from Shizuoka is yearly on the
up grade in volume. The Fuji and Kyodo
Companies at Shizuoka, as well as the local
branch of Messrs Jardine, Matheson & Co.,
have already commenced the necessary pre-
parations. The favourable market conditions
there will be maintained as hitherto in compe-
tition with the Yokohama market. It is ex-
pected that nearly all the representatives, in
charge of tea, of various foreign firms in Yoko-
hama will return to Yokohama by the ‘‘Siberia,”

THE MYGOLOGIST GIVES WARNINGS
ON RUBBER TAPPING,
Anp tHe NorTHWAY SYSTEM.
We direct the attention of our rubber-plan-
ting readers to the warnings given by Mr.
. Petch, the Government Mycologist, on the
question of rubber tapping; and specially should
they note the injunction that on no system
whatever is it permissible to tap over more
than half the circumference of the tree at
the same time, The Northway system directly
contravenes this rule; the tapping, we be-
lieve, 18 carried on right round the stem. We
do not know that this is fatal tu the system, how-
ever, for it is possible that the system could be
modified in this respect if the present method is
found to be injurious to the tree. In this con-
nection a Colombo Estate Agent, answering an
enquiry today, says :—‘* The Northway system
is on its trial. Deviturai trees were doubtless
heavily manured; and poor and unmanured trees
will not give the rush of iatex which can be
shown to visitors by Mc. Northway ; but I have
no doubt damage by his system is being done
(as at first by the old V method) owing to care-
less work, and tapping trees which are too young
with thin bark through which the pricker goes
into wood—also, by the cutting through of thin
bark by hoop-iron channels which in some cases
have been stuck in without regard to their
effect on the bark.”

Sim,—Your readers should be warned that on
no system whatever is it permissible to tap over
more than half the circumference of the tree
at the same time. This is the maximum, where
trees of small girth must be tapped for finan-
cial reasons; the optimum is about one-quarter
circumference.

about 1,2c each. They were packed in dry charcoal in seed

SAN PAULO’S COFFEE SCHEME.
How ‘‘ VALORISATION” I8 PROCEEDING.
Ata meeting of the Committee charged with the
management of the State of San Paulo Govern-
ment coffeo, held today under the chairman-
ship of Baron Bruno Schréder, the following
statement was approved :—
1. With reference to clause 2 of the circular dated
January 5, 1909, the Committee states that no sales of
coffee have been made, that the contemplated sale of
500,000 bags will not be undertaken until the trade is ready
to pay the price stipulated therein, or its equivalent in
any of the markets, and that in no case shall the sales
during the current year exceed 500,000 bags.
2. Vhe Government has lately had under its considera-
tion the advisability of replacing the existing law, limi-
ting the export of coffee, by
A NEW LAW CREATING AN EXTRA DUTY
of 10 per cent on all exports of coffee payable in
kind, such coffee to be destroyed under the control of the
Committee. This law would, in the opinion of the
Government, bring aboutthe same result as the existing
law, but in a more satisfactory manner. The change
would appear to the Government to be most desirable, as
it would obviate the rush to market the crop, which
would undoubtedly take place under the existing law; the
planter would thereby be given time properly to prepare
bis coffes, the exports would then, as in former years, be
spread over the whole 12 months, and the qualtty, of the
coffee reported would bo improved by the destruction of
the lowest grades. Such alteratiou of the law would also
bo desirable in the interests of the coffee trade, of labour,
and of the railway and shipping companies, and would at
the same time assure the stability of the exchange.
The Guvernment has now approached the Committee
officially on the subject, having set forth its reasons. as
above, for desiring an alteration of the law, and the Com:
wittes, after careful conslderation of all interests, is of

RUBBER IN SUMATRA.
PROGRESS ON THE EAST COAST.
The opening of the east coast of Sumatra
(Sumatra Oostkust) goes back to tho ‘sixties
when tobacco was first grown by Kurcpeans.
Why was this parf of Sumatra opened in pre-
ference to any other on that side of the Straits
of Malacca ? Was the soil unique in its com-
position as tobacco requires it to be? Was it
ecause Deli and the neighbouring districts lay
nearer to the busy island of Penang, an old
landmark on the trade route between Europe
and the Malay Archipelago ? As with ali sub-
sequent wonderful developments, the origin of
tobacco cultivation on the east coast is sur-
rounded by legends. Tho tact, however, re-
mains that the attention of Kuropeans was one
day attracted to Sumatra tobacco grown by
natives on the vast coast, and from that date to-
bacco has been and remained the agent of the
whole progress of the east coast, progress un-
paralleled elsewhere in the Kast except in the
F.M.S.
Tho measuro and peculiar significance of that
progress is to be judged from the official statis-
ties (1906)—the only reliable source of informa-
tion. Whereas, for the same extent of territory,
the west coast has an excess of officials over non-
officials (409 officials, 88 traders, 34 contractors,
and 42 planters), the east coast stands in the
opposite relation (134 officials, 146 traders,
307 contractors and 507 planters). The prepon-
derance of officials in the west is to be explained
by the greater density of tho native population,
its better climate, and in Padang, up to quite
recently, the coffee cultivation under Govern-
ment control.
The preponderance of civilians in the east is
due to the development of tobacco cultivation
asa private enterprise. Striking features ap-
pear in the statistics for the east coast, the low
density of the native population, the high per-
centage of imported races, Chinese and Javanese
especially, Klings, -Bengalis, etc. Let us ox-
amine those features before we pass on to what
concerns us here—the work of Europeans, with
epecial reference to rubber and their life gene-
rally.
THe Native PopuLation,
Tobacco is not responsible for the low density
of the native population, as, for instance, rubber
has been in vast districts of the Congo, although
it has accommodated itself rather well to the
situation. For greediness of laud tobacco is un-
equalled. 1t devours larger and larger spaces
until after eight years it can come back—with-
out prejudice—to its growth in the soil it first
occupied, Reservations for natives would neces-
sarily stand in its way, and it was not a misfor-
tune that the country was more or less empty.
Java would have been an awkward place for it
to move about in. Going from Tandjong Balei to
Tandjong Poera, that is, from south to north-
for milesand miles one sees endless strips of land
covered with lalang and blukar where tobacco
has passed and left devastation behind. One
longs to arrive at kampongs, which are like so
583
many oases in that desert. ft must be con-
fessed, en passant, that the sight is less unseemly
than that of the scars and holes that disfiguro
beautiful spots in mining districtsin the F M.S,
THE CHinese IMMIGRANT.
Just as in the F.M.S.—always one’s standard
of comparison when one wants to measure the
progress of other colunies—the country has
been opened and developed by the Chinese
before the advent of the god Rubber;in the
same way Sumatra’s east coast has looked for its
labour to China, I say “has looked for its
labour,” for there has been no initial Chinese
enterprise except in the petty trade of the
towns. ‘The Chinese cannot obtain conce ssions.
The Dutch tobacco companies have protected
themselves against their possible competition.
Kich towkays would have commanded Chinese
Jabour to the exclusion of any other and might
have proved a state within the State. As it is,
the Chinese represent 20 per cent. of the popu-
lation, But their community has no perma-
nency, owing to its special character, being
composed almost entirely of men (88,856 unmar-
ried as against 9,877 married.) The few rich
Chinamen are the captains of an army (the ex-
pression “Capitan China” is not inappropriate)
rathor than the heads of a community.
Their influence over the coolies is great, but
the coolies will remain a huge army which can
be disbanded when its services are no more
wanted. That event we shall not wibtnoss.
Tobacco would have to cease to exist, and, as
we shall see, Dutch people do not believe in its
disappearance. The high percentage of the Chi-
nese population can only be counterbalanced
by an influx of another imported race, and that
the rubber industry can be expected to bring
about—as it is doing in the F.M.S. with Tamils,
LaBour.
Javanese are the imported race on rubber
plantations in Sumatra. The cost per coolie is
80 guilders (1 guilder=70 dollar cents), 30 of
which are recoverable, Though the contract
lasts three years only, the coolies, on an ave-
rage, remain seven or eight years, which brings
the cost of recruiting to about the same as in the
F.M.S. The source of supply is inexhaustible
which ismore than can be ‘said of the Tamil
districts in Southern India. If we add that
climate and soil are as good as inthe F.M.S8
one can look forward to an increase in the
acreage under rubber. That increase will
receive a great impetus once Dutchmen en-
gageinit. Up to the present no Dutch com-
pany has been formed for the purpose of
planting rubber. The Dutch tobacco com.
panies have. more’ than 350,000 acres
wholly unsuitable for tobacco, though in most
parts very good for rubber. They pay a quit
rent of 1 guilder a bouw (1? acre) for land
that cannot be used, and yet they will not part
with a plot of it, even when it would oblige a
rubber company, their neighbour. It would
take away something from their standing and
dignity. The only tobacco companies that have
taken up rubber are English, the Shanghai Su-
matra Tobacco Co., the United Langkat and
Paya Jambu. A fow small tobacco properties
belonging to private individuals or defunct com-
panies have also been turned into rubber estates,
584
Op Correrk Lanp,
The greater part of the coffee land has been
put under rubber, most of the estates under-
going the same transformation asin Malaya; and
all of them were started with Swiss or German
capital. Their rubber is not very old and not
kept up tothe mark, owing to lack of funds.
The soil is not alluvial, as was most of the
soil under coffee in the F. M. 8., but had
it received proper care and attention, it
would show ultimately a better growth and
a heavier yield in rubber, judging from
similar soil under more fortunate circum-
stances. This leads me to consider the position
of estates belonging to companies with more
capital. The work dons is impressive, both on
account of the short time allowed to managers
to put it through, and the large scale on which
it has been done. Very little of the land was
virgin forest ; a great deal of it was lalang, and
much of the remainder was and is under coffce.
The growth is good on lalang or old tobacco land,
and this is what surprises one most, Though
looking for the difference between the product
of either class of soil and virgin forest, one is
almost disappointed not to find it. The only
rational explanation would be perhaps that
lalang or old tobacco land has been dug over a
sufficient number of times to make it as good as
virgin land which has not been turned over at all.
LALANG V, JUNGLE,
The moncy disbursed for getting the soil ready
for planting amounts to very much the same for
lalang and virgin forest, for the following rea-
sons : felling is dear, whereas digging lalang or
blukar is cheap, the latter process being often
resorted to. ‘Thus, taking all these circum-
stances into consideration, we are gradually
led to understand the following assertion of a
Sumatra planter: ‘‘[f I were to open again, |
would rather open on lalang er tobacco land.”
Planters, who are now struggling with fungus
and white ants, will fully appreciate this view,
The hosts of virgin forest are not to be go
easily driven out of their abode unless
every stump and root is taken out and burnt.
Then it is no more clearing the jungle as in the
old days; it is modern cleansing with all its
cortege of machines. The expense of opening
jungle land is therefore increased, but in that
case the earth has necessarily been turned over,
and the returns must prove greater than in the
case of previously cultivated Jand. There is
much of this latter class in Sumatra, and it will
be interesting to see what yields 1t gives. The
experiment was needed.
A Goop ScHooL,
The impression one carries away is that
tobacco is a very good schcol for planting life.
Comparatively young men acquire great exper-
jence in handling large and mixed labour forces,
and older men, in managing the huge resources
placed at their disposal by their powerful com-
panies. English planters, from want of previous
experience, might encounter more difficulties in
dealing with such bulky concerns. The training
has been longer and not so chequered and in-
terrupted as in Ceylon and the ¥.M.S. It is
quite normal to hear of Europeans having only
been home twice in 20 years. The only holidays
The Supplement to the Tropical Agriculturist
are the Ist and 16th of the month—no Sunday
rest. The work is hard and especially exacting
in May, June and July—everybody in the field
at 5-30 a.m., back at ll a.m., and out again at
1 p.m. till 6 p.m.
SPANDARD OF LivING.
Against this, living is on a higher standard
than in Ceylon or the F M §&., judged
from the point of view of food and houses.
It is a real pleasure to go to a far-away
estate and find fresh milk, fresh butter and
new-made bread, instead of tinved or stale
articles. The meat is excellent, owing to the
presence in the country of Kuropean butchers,
who cater for the other Europeans. It isa pro-
fitable business and not below their dignity. By
the way, why should it be infra diy, to trade
in fresh products, and not so to deal wholesale
in tinned ones? There is no objection amongst
Dutch people to keeping a shop or managing a
hotel, and consequently there are good shops
and good hotels.
In Sumatra, as in Java, the houses are very
comfortable, being well furnished and provided
with all the conveniences that may be found in
Europe. The tobacco companies have not be-
grudged the money for the grounds surrounding
managers’ houses, with the result that the latter
are laid out with a certain grandeur. Sumatra
planters are fond of saying that assistants in
the FMS are sometimes put in bungalows
where they would not put their coolies.
The Impression throughout is that Europeans
are there for a longer time than in the FM§,
and it is confirmed by their relations with the
natives and their treatment of the Eurasian
question. One realises that every detail of their
hfe isin accordance with the rest. The travel—
jer in Sumatra, as elsewhere, notes that every
country has stamped its colonies with the mark
of its own nationality.—Malay Mail, May 11.

THE CULTIVATION OF THE
ALMOND TREE.
( Special.)
The common almond tree (Amygdalus com-
munis) is a native of Asia Minor andthe North of
Africa where it has been cultivated from ancient
times. One of the earliest references to it is
found in the Old Testament. The fruit is either
sweet or bitter—a fact which many botanists
have endeavoured to explain by a differenco in
species. The probability is that the original
almond was bitter and from it the sweet almond
was produced by selection, the latter being after-
wards brought to perfection by careful culti-
vation and broken up into a number of varieties.
In the cultivation of the almond in modern
times the
FIRST RANK HAS BEEN CLAIMED BY FRANCE,
from which country the best and the best-
known varieties are, for the most part, obtained.
Some of these varieties, which belong to the class
of the sweet almonds, are known as Amande des
dames, Languedoc, Sultana, Pistache and Douce
a coque dure, and each is characterised by the
size, form, flavour, etc., of its fruit. This
position, however, occupied by France, has
recently been imperilled by the formidable
rivalry of California, which has succeeded in
producing several new valuable varieties such as
Excelsior, Non plusultra, Nonpareil, Il Suprama
and Commercial. The latter deserves special
mention. The tree exhibits a peculiar com-
pressed growth and retains some leaves until
the end of winter. It is very prolific and the
almonds, provided with a thin husk, are
sweet, delicate and very large. In the
trade, however, the
JORDAN ALMONDS ARE PKIZED
the most. These are not, as is commonly sup-
posed, produced on the Jordan, but in the
neighbourhood of Malaga (Spain). No doubt
their good qualities are due to the influences of
soil and climate, for this variety does not meet
with the same favour in other countries. Next
in order of merit come the broad almonds of
Valencia, to which the previous remark is also
applicable. The almonds of Provence are
also renowned, which is indicated by the fact
that in the commercial city of Aix the annual
turn-over in this commodity reaches the value
of £125,000. France’s total exports of almonds
to foreign countries are valued yearly at £800,000,
THE SWEET ALMONDS
contain considerable quantities of a very delicate
fatty oil, also sugar, gum and mucilage. Beside
being very nutritious they possess a pleasant
taste. They are used for the most part in fancy
bakery, in the kitchen, as dessert and in medi-
cine for the purpose of making cooling drinks.
The bitter almonds contain the same substances,
but in addition Amygdalin, from which a pecu-
liar volatile oil is prepared. This oil, when
puritied, is likewise used in the kitchen and
fancy bakery but also in the toilet soap factories
for perfuming purposes. In the impure state
it is sometimes employed in medicine in place
of pure prussic acid,

The almond tree
THRIVES BEST IN THE SUB-TROPICAL ZONE,
where it is indeed a native, for neither a
moist nora cold climate is favourable to its
growth. In the warm revions of the temperate
zone, however, its cultivation is also successful;
only the harvests are always very uncertain on
account of the injury that is often inflicted by
the frost on the early shooting buds. The
sweet almond is even more sensitive to cold
than the bitter one,and consequently its sphere
of cultivation is much more limited. This fact,
combined with the keener demand there is for
it renders the sweet almond dearer in price and
therefore, its cultivation more remunerative.
For this reason the preference should always
be given to the cultivation of the sweet al-
mond; that is, in those places where the cli-
mate and soil are quite suitable. Like the
fig tree, the almond cannot stand the exces-
sive moisture of the tropics and it is only
grown there at the expense ofits fertility. The
CLIMATE AS WELL AS THE SOIL SHOULD BE WARM
AND DRY;
addition, must be free and
possible, rich in lime
—such a soil, in fact, as is required for
the cherry tree in the temperate zone. The
most favourable situation for its cultivation is
on the ridge or slope of a hill, Level land
should only be chosen when there is no
danger of it being flooded. While a large
amount of moisture is injurious, it is also im-
portant that the needs of the almond tree are
completely satisfied in this respect. It has
been found by experience that artificial irri-
gation has a detrimental effect. Although the
tree is not specially sensitive to wind, it should
not be left exposed on all sides. If there is
no protection afforded by elevated ground, a
natural barrier in the form of trees may be
set up to break the force ef the wind. For the
CULTIVATION AND PROPAGATION OF THE FINEST
varieties of the almond tree, grafting is
also essential, and this gives rise to the ques-
tion: What are the most suitable trees to use
for this purpose? The selection of these will
depend, to a great extent, on the soil and cli-
matic conditions. In districts, for example,
where it is desirable that some power of with-
standing the influences of the weather should
be imparted by the process, the plum tree will
be found the most advantageous (Myrobolama
excepted}, and especially’ the fast-growing and
early ripening varieties. The grafting should
be done on a twig not thicker than } inch ;
otherwise the growing over, of the part where
the grafting has taken place, will last too long.
If, on the other hand, the soilin question con-
tains more moisture than is good for the
almond tree, the peach tree, as being partial
to a moist situation, should be chosen asa
base. In the case of avery dry soil, however,
it is recommended to employ the almond tree
itself and preferably the bitter variety, if the
soil and climatic conditions are favourable to its
growth. Where the latter is not available, the
hard-husked sweet variety or even one of the soft-
husked varieties may be taken for the purpose,
In the growing of almond trees for the
purpose of grafting, the seeds should be first
the latter, in
deep and, wherever
586
pressed gently on the sides until the out-
side green husk is no more than evident.
Care must, of course, be taken in the process
that no harm is done to the kernel, The seeds
are then put into a carefully prepared bed at
a distance of 6 inches from one another and
covered with light fine earth toa height of 2
inches. If protection is necessary against vermin
some lime and ashes may be spread over the
seeds. In districts where the wiuter is so severe
that the sowing of the seeds harvested in the
summer or autumn must be postponed until
spring, or where the postponement is deemed
advisable, the seed should be placed in slightly
moist sand and stored in the cellar during the
interval.
When the trees areas thick as a pen-holder
they are grafted 1—2 inches above the ground.
Inthe sub-tropics when the treesare well-treated
THE GRAFTING CAN TAKE PLACE IN AUGUST,
provided that the seed was sown in the spring
or in the previous autumn. The transplanting
will then be carried out in the following spring.
The most suitable distance to be left between
the trees is 5 yards in each direction; it is
only in dwarf culture that the distance can be
reduced to 4 yards.
The harvesting of the almonds is simple and
convenient. It is only necessary to wait until
the green outside fruit husks have sprung open
when the almonds, which have fallen out, may
be picked up from under the trees. This, how-
ever, requires a good deal of time, for the
springing open of the husks does not take place
within a narrow limited period and is besides
only incomplete in the case of many varieties.
It is preferred, therefore, in the larger plant-
ations to pluck the almonds like other fruit
and break open the husks after they are brought
into the granary. Thisis alsoa slow process
if carried out by means of a wooden hammer,
so that the invention of a machine for
doing the work is a ‘‘consummation de-
voutly to be wished” by the almond cultivator.
FERTILISATION,
With regard to this subject there is unfortu-
nately not much available data on which to
base conclusions, but the facts that are known
are presented here for the consideration of the
reader. The amount of plant food contained in
the leaves and branches of the almond tree is
practically immaterial for our purpose, as_it is
for the most partreturned to the soil, What
we must consider is the quantities of the im-
portant constituents that are withdrawn per-
manently from the soil through the medium of
the fruil. According to the analysis of Zedeler,
the almond contains :—
38°20 parts per 1,000 of Nitrogen
13°70, aa 3 99 Potash
», Phosphoric acid
», Lime
£30 aisie he stah se
A tree, therefore, in full bearing, which yields
annually 45 1b of almonds (without husks), will
remove annually from the soil :—
1°68 lbs Nitrogen
0°60 ,, Potash
0:94 ~,, Phosphoric acid
o'19 ,, Lime
The Supplement to the Tropical Agriculturist
Assuming now there aro 40 trees to the acre,
we find that the quantities of the important
fertilising ingredients removed per acre from
the soil by the corresponding crop of almonds—
1,800 tb,—are :—
67°2 Ib. Nitrogen 37°6 lb. Phosphoric acid
24:0in. Potash (Pas Lime
From these figures it is plainly evident that,
if the almond tree is to maintain its prolifity,
the soil must be replenished with the proper
amounts of plant food. How is this to be ac
complished? In the first place, it will be neces-
sary to find an economic method of supplying
Nitrogen, for it would prove too costly to
apply this constituent all in the form of
chemical manures. From the figure given
above there would bo necessary for this purpose
no less a quantity of Nitrate of Soda than 3}
cewts. per acre. It is preferable, therefore, to
have recourse to green manuring and to supple-
ment this with small quantities of Nitrate of
Soda or Sulphate of Ammonia.
On calcareous soils, or soils which are not poor
in lime, Sainfoin should be cultivated every
third, fourth or fifth year and ploughed in at the
time of flowering. This will supply with roots,
stems, etc., at least 180-220 lb. of Nitrogen per
acre, corresponding to 10,000-13,000 Ib. gresn
material. This manuring along with an appli-
cation of 2-24 lb. Nitrate of Soda or Sulphate
of Ammonia per tree will provide sufticient
Nitrogen.
On sandy soils it isadvisable to grow lupines
every second or third year. This crop, buried
in the green condition, will supply 130 Ib.-
Nitrogen per acre or 13,000 lb. of green material.
Inthe case of many sandy soils or sandy-
loams the better plant is Bird’s-foot (Orni-
thopus), which will supply 10,000 lb. of green
material, equivalent to 120 lb. of Nitrogen per
acre, It is recommended to cultivate this crop
every alternate year, In the same way, many
other leguminous crops may be grown for the
purpose of enriching the soil with Nitrogen, but
at the same time it will be found advantageous
to supplement this method by the application
of artificial nitrogenous manures at the rate
indicated above.
Referring again to the figures at the begin-
ning we find that each almond tree requires
yearly 060 1b, Potash or 40 trees (occupying
one acre) 240 lb. To restore this constituent to
the soil, ong of the three following salts should
be applied and at the rate suggested :—
Per Tree Per acre (40 trees)
Sulphate of Potash 14 lb. 60 Ib.
Muriate of Potash nn “4
Kainit 6 lb. 240 lb,
The Sulphate ot Potash should be employed
preferably on the heavy soils deficient in lime,
while the Muriate is to be reserved for those
containing sufficient lime and Kainit for the
sandy soils.
With regard to phosphoric acid we observe
that each tree is responsible foran annual loss
of 0°94 lb. or 40 trees (occupying 1 acre) 37°6 lb.
It will, therefore, be necessary to use the fol-
lowing quantity of one or other of the phos-
phatic manures :—
Per tree.
Superphosphate 5 Ib.
Basic Slag 6 1b.
Per acre (40 trees.)
200 Ib,
240 Ib,
and Magazine of the Ceylon A gricultural Society.
In cases where tho soil is well supplied with
lime it is recommended to use Superphosphate,
and Basic Slag wherever there isa deficiency of
this constituent,
Asa summary of the foregoing remarks, the
following manurial prescriptions, in addition to
greeu-manuring, may be laid down for the
different classes of soils :—
I. Heavy soils deficient in lime.
Per tree.
Basic Slag 6 lb.
Sulphate of Potash _ 13 5,
Sulphate of Ammonia.. Dees,
Ii. Soils containing sufficient lime.
Per tree.
Superphosphate 5 Ib.
Muriate of Potash Ws
Nitrate of Soda 2h yy
III. Sandy Soils.
Per tree,
Basic Slag . 6 lb.
Kainit ie (a
Sulphate of Ammonia... CAPR
These manurial recipes, of course, apply only
to trees which are in full bearing. In the case
of younger trees and trees planted more closely
togethor, the quantities of the different manures
fer application per tree will have to be lessened
and calculated in the same way according to the
yiold per acre,
The above calculations were also made on the
assumption that the soil on which the almond
trees are cultivated is naturally poor. If the
soil be fertile, however, it is clear that tho
quantities of tho manures may be correspon-
dingly reduced. It is impossible here to enter
into details, but it may be stated generally that
the best and surest method of determining the
requirements of the soil is to carry out suitabio
experiments.
While the phosphatic and potash manures
should be applied and ploughed in ix the autumn,
or at the beginning of the winter, the Nitrate
of Soda or Sulphate of Ammonia will be more
advantageously appiied in the spring and in-
corporated with the surface soil.
In soils which contain an abundance of lime,
good effects will be produced by tho use of [ron
Sulphate applied at the rate of 40-70 lb. per acre.
In order to show finally the actual advan-
tages that may be obtained in practice by the
judicious manuring of the almond trees, we
may quote the results of an experiment carried
out in 1907-08 by Mr Emilio Albiach in Ali-
cante, Spain. The trees, which were 20-25 years
old at the time of the experiment, had been
previously manured merely with the ashes of
the husks. Three plots in all were taken and
while one was feft uamanured and another
received Superphosphatoe, 330 lb. per acre, and
Nitrate of Soda and Sulphate of Ammonia each
80 lb, per acre, the other plot got the same
quantities of the iast-mentioned materials and,
in addition, a dressing of Kainit at the rato of
450 Ib, per acre, that is a ‘‘ complete manu-
ring.” The Superphosphate, Sulphate of Arm-
monia and Kainit were applied round the base
of the trees on the 5th December, 1907, and the
Nitrate of Soda in the following spring, one
half in March and the other half in May, The
587
harvest took place on the 28th August, 1908, and
the results may be represented as follows :—

Comment on these results is needless. They
testify clearly enough to the practical im-
portance of restoring to the soil in the culti-
vation of the aimond the three chief ele-
ments of plant food—Nitrogen, Phosphoric Acid
and Potash.

CLEAN-WEEDING RUBBER ESTATES.
May 14th.
Dear Six,—A good deal has been written on
the subject of clean-weeding rubber estates,
Both those iu favour of, and against the system
have much to say in support of their convictions
which deserves serious consideration. But
what the rubber planter wants is the ultimate
analysis of the whole question, Personally, I
find that clean weeding tends to promote
greater growth of the tree, and this is generally
acknowledged. Jf exposure of the soil results
in surface deterioration, it obviously does not
affect the plant injuriously, while the decidu-
ous character of the Para rubber tree would
seem to prevent impoverishment of the soil.
Then again, clean weeding is only necessary
during the first few years of the life of an
estate, 7,.¢. until the branches of the tree afford
over-head shade, If, therefore, the planter
. finds that clean weeding helps the tree to grow
more quickly, returns on his outlay are sooner
realisable, This is a consideration not to be
neglected unless if can be conclusively proved
that clean weeding during the earlier years of
the existence of a plantation affects it injuri-
ously later on,
I have adopted a system of clean weeding
along the lines of the trees, and at right angles
to the slope of the ground, which seems to me
to serve several useful purposes. The root
areas of the trees are kept free from noxious
weeds, and light and air are freely admitted.
The cleared strips form paths which facilitate
inspection of the estate, and the uncleared
strips of scrub between the lines of trees pre-
vent wash and thus eavethe expense of drains,
whilo affording protection to the young rubber
against wind.

RUBBER PLANTING IN THE STRAITS.
AN INTERVIEW WITH MR. E, V. CAREY.
Mr, E. V. Carey, the well-known rubber
planter of the Straits, was spent a fortnight in
Ceylon on his way home, was good enough to
give a Ceylon Observer representative a full ac-
count of the present conditions and future pros-
pects of rubber planting in the parts which he
has just visited. Everything, it seems, was
flourishing extraordinarily in the Straits and
things were going on satisfactorily in every way.
CROTALARIA AND Passion FLOWER.
One question was greatly interesting planters
there, that of growing crotalaria and passion
flower. ‘‘ Personally,” he said, ‘‘I don’t think
there is any one of them to be compared to
clean weeding, simply on the score that on a
clean estate a manager can supervise a very
much larger area of land. Management is none
too easy a question and to have the burden of
attending to these different products, that are
planted to keep weeds down, means an
enormous amount of extra supervision. In
some cases out there you see crotalaria over
a@ man’s head and it is impossible to supervise
a gang of coolies working in stuff standing over
their heads. How about
Mimosa ?
I don’t think there’s a single advocate of
mimosa in the country. It is full of thorns,
which cause coolies’ feet to ulcer badly, and alto-
gether, as far as I can judge, it is quite an
undesirable thing as compared with passion
creeper. There 1s a good deal to be said for
the passion creeper as long as itis the fashion
at whatever cost to try and thoroughly clean
land of weeds, which are probably in themselves
almost harmless, such as small -needle grass,
and the plant known as valacha which Ceylon
planters know very well. From what [
saw, passion creeper on land which is extraordi-
narily expensive to weed, and I am not inclu-
ding lalang in that, ought to be a very useful
thing indeed. It is very easily cultivated on
most lands and very easily exterminated; and
there is no doubt that it kills all the weeds
under it. It forms a tremendous thick blanket
on the ground and the weeds don’t have a
chance with it. They aresimply choked. I have
not sufficient experience to say that it is going
to do an extraordinary amount
To Krrp Latane Down.
1 was told in one place in which the lalang
had been cut out, and probably not properly
eradicated, that the passion creeper had taken
a tremendous hold to start with ; but that after
some timethe lalang began to shoot up through
it. I think that most old planters feel that
clean weeding is the best thing, and next to
that this passion creeper. Crotalaria does not
seem to kill weeds, although it chokes them.
TAPPING.
And how about the tapping yield ?
The tapping yield is all thatcould possibly
be expected, and better. Tapping on most estates
that I saw was very carefully done and all the
The Supplement to the Tropical Agriculturist
men that I spoke to seemed to take a very
keen and intelligent interest in the whole thing,
especially in the way in which the trees were
treated, and they have the uld Ceylon spirit of
thoroughly discussing and thrashing things out.
Tue Nortuway SystEM,
There is a lot of talk about the new Northway
system of tapping, although nobody has any
data to go upon. The general feeling seems to
be that it is impossible to handle the pricker so
carefully that it won’t penetrate the cambium
and wound the wood. Our experience has been
that wherever the wood is wounded, you get a
knotty uneven development of the bark and stem,
instead of a smooth healed surface; and a good
many men appear to fear that people who com-
mit themselves to the new pricking system may
possibly create a condition of things in the
shape ofthe trees which will render any ordinary
methods of tapping by knives practically an
impossibility in the future. I have no per-
sonal experience of any of this suggested
damger in connection with the Northway
system of pricking and I only repeat what
people say and seem to fear, my own expe-
rience being confined to the definite knowledge
of what results from wounds generally but
not particularly in connection with pricking.
It seems to me that we get very satistactory
yields indeed; with a minimum of damage to
the trees, by the ordinary shaving provess, and
I think that the adoption of this new idea is
rather a case of forsaking the substance for
the shadow. I will not allowit on any estate
with which I have anything to do although I
shall, of course, be very glad to benefit by the
experience of others.
Tur YirLD UNDER THE EXISTING SYSTEM.
Can you give me any figures as to yield under
the existing tapping system ?
Well, I can tell you that, on one estate, trees
which are from seven to nine years old are now
considered to be in full tapping order, and
are yielding an
AVERAGE OF SEVEN POUNDS A TREE,
I can also tell you that at my own place I am
getting this year 400 lb an acre from trees plan-
ted 10 by 10 which are 53 to 63 years old. The
feeling out there seems to be that in close
planted rubber the renewal later becomes thin
because it appears to be in direct proportion to
the leaf head that the tree carries, and therefore
it seems likely that in my own particular case,
10 by 10 planting, there will have to be thinning
out in the future.
THE NuMBER OF CooLiES REQUIRED.
How many coolies do you want for an acre?
At the present moment I have a force amoun-
ting to onecooly anacre. I have 187 acres being
tapped and I have a force of under 200 coolies
all told. These coolies, in addition to working
all that, also weed another 275 acres, roughly,
and keep them in order. The whole opened
area is 450 acres and I have at present a force of
something like 200 coolies. That, however, is
insufficient and I am going to double my force,
because I believe that one should always have a
considerable margin of labour, for the reason
and Magazine uf the Ceylon Agricultural Society.
that trees are constantly coming into bearing
and that their produce should be extracted
instead of being left in the tree. The ideal of
tapping seems to be that every quarter all the
trees that have then attained the minimum tap-
ping circumference, whatever it may be, 16 or 18
inches, should be at once handled instead of
being left idle, and that all the trees that have
matured up tothat point should be taken regu-
larly as they come on. I should think that
when all the trees are in bearing, one cooly per
acre would be a perfectly safe maximum for
tapping purposes. I am, with the force men-
tioned above, getting 400lb.an acre, but itis
only in its second year of bearing.
THE Cost of PRODUCTION.
Is the cost of production of rubber being
reduced ?
Well, 1 can’t teli you that exactly. They are
always improving.
Do you think it will ever be put on the market
at 6d or 8d per pound?—I don’t see later on why
it should not be put on at 9d. per pound.
A Surricrent Laspour Force.
Do you think the labour force suflicient in the
Straits P—I do, but the system has, of course,
its apparent drawbacks.
FREEDOM FROM DEBT.
Do you agree with Mr R W Harrison that it
is a bad mistake to Jand the coolies on the
F.M.S. estates free of all debt ?
No. I don’t. [think it is a very good thing
as a general advertisement for the country.
The individual may feol it, perhaps; but as a
general advertisement for the country, 1 don’t
think there could be a better scheme. I| think
myself that speaking generaliy it is a splendid
war cry for all recruiting that the coolies are
landed without any debt. Obviously it must
be. I don’t see how it can be refuted, If
there is animpression broadcast in the villages
that a cooly when he comes over, whatever has
been spent on him. has nothing to repay, it
must have a good effect. The advertisement of
being able to come over free of debt seems to
me of enormous value to the country.
Does not the fact of their being free from
debt give you less hold on them ?
No. I don’t think so. As far as I under
stand it, the attitude of the Gevernment is that
if a cooly has a debt,the only process of recovery
is a civil one. You can’t make a cooly stop
longer than he wishes; and if by bolting he can
evade a debt which is a burden to him, it seems
to me that he is likely to do so. He is less
likely to bolt if he has not got that burden.
On Juara ISLAND,
The Jugra Island property is of course surroun-
ded by water. No spirit of any kind is allowed
on the place and therefore there are no attrac-
tions to coolies to enable them to squander their
money. During this year, up to date, over
R10,000 have been remitted to India from that
place alone, through our manager, who remits
all their savings, at the rate of exchange of the
day, without any cost to the cooly. Planters are
trying to get coolies as hard asever they can and
589
they aresaid to be coming in lots cf 10, 15 and
20 men. On Jugra Island, however, there have
been four shipments of 40, 75, 90, and 125. From
what I could find out there was no parallel in
any other property to anything of the kind. I
attribute that directly to the fact that owing to
our insular position and the fact that our labour
is all raw material from the Coast, the coolies
have not got into touch with the gin shops and
other inducements to spend money and they
remain at home. Their relations and friends see
the money coming over, they think itis a good
country to go to, and they go.
THe Estate Kappt System.
We supply all our stuff from the estate kaddi,
practically everything that the coolies require,
On pay days if they want things they cannot get
from the estate kaddi they are, up to a certain
number, allowed togo to Port Swettenham in
order to get what they want.
Do you think the kaddi system a good one?
Yes, a thoroughly good one. I am the firmest
possible believer in direct financial arrange-
ments between the superintendent and each in-
dividual cooly. I don’t believe in letting the
kangani have any financial power whatever over
the cooly and I believe iv helping the cooly to
avoid chetties, shopkeepors, and all people who
live on his stupidity. That is the secret of pro-
per organisation and control. I don’t say itis
possible in Ueylon, but I believe it is.
THE HEALTH OF THE COOLIES,
How about the health of the coolies ?
The health varies very much in different
places, but speaking generally one does not hear
so much about ill health as before. On ourown
piace, Jugra Island, for instance, the day that I
went into the hospital [ found three in the hos-
pital out of a labour force of something like
1,700. I think that on the whole the conditions
are in favour of labour going over,
SANITATION,
Have you done much in the way of sanitation?
There isa movement on the part of Govern-
ment now to regulate sanitation pretty closely
in connection with this
ANCHYLOSTOMIASIS,
There is no doubt whatever that it isa move-
ment in the right direction because the anaemic
condition of the coolies, which is directly due
to anchylostomiasis, is very pronounced and
very common, especially when they come over
from the coast, but the Government must be
very careful how they get towork. They are
trying to introduce the latrine system but
there are difficulties in the way and they must
proceed cautiously. They must be careful, for
instance, not to run up against caste prejudices.
WHITE ANTs.
Mr. Carey then referred to the trouble caused
by white ants and fungus and said :—
I don’t think the white ants area very serious
thing at all. I believe planters have the con-
trol of them on quite simple lines, entirely in
their own hands, but I don’t think the subject
has been as carefully gone into as it should
have been during the last few years and con-
590
sequently ants have got established on patches
of estates and they take some time to eradicate.
The new pump, by means of which a hole is
bored in the tree and gas forced in, is likely to
doa great deal of good. In one case I heard
of, fumes were forced into a trea and came out
of another 30 or 40 feet away. All the ants
in that area were destroyed. Lhe nests must
be got at and destroyed. There is a system
now of putting on a gang of men to examine the
old logs right through the estate, even when
there are no particular outbreaks of ants
to warrant it, in the hopo that the nests will be
discovered and destroyed before the ants
actually begin to attack the rubber. It 13 a
remedial measure, a very sensible one, and the
expense is not at all heavy.
Funaus.
There are all sorts of different stories about
the fungus; but the general idea seems to be
that if you have an alert Superintendent, he
can isolate attacks by means of drainage. A
trench is cut right round the spot where the
fungus is, the ground is then thoroughly dug up,
all wood carrying any trace of fungus on it 1s
destroyed and the ground is very freely limed
with the result that they seem to be able to
handle it quite easily. 1t does not seem to
attack trees of over three years of age,
Proeress on JuGRa ISLAND.
Finally, Mr. Carey, can you tell me what
progress has been made lately on Jugra Lsland ?
We started work in August, 1996, and by
the end of this year we shall have 4,000 acres
planted, mostly in rubber, although a few
hundred aeres will be in coconuts, We have
not got anything more than 20 months old.
We extended our programme from 2,000 to
4,000 acres and issued £42,000 of convertible
debenture stock to enable us to doso. Over
£100,000 was subscribed about 6 weeks ago and
the prospects are very fine indeed.
VULCGANIZATION TESTS IN PLANTA-
TION RUBBERS.
AT THE SOCIETY OF CHEMICAL INDUSTRY.
Methods of Preparation more important than
ages of trees.
At the meeting of the London section of the
Society of Chemical Industry, held on May 3,
Dr J Lewkowitsch being in the chair, Messrs
Clayton Beadle and H P Stevens described
certain chemical and physical tests made on
samples of rubber from plantation block, crépe
and biscuit from young and old trees, and also
a specimen of fine hard Pararubber. These
experiments were made on the raw rubber, and
on this material vuleanised either with sulphur
only or with sulphur and mineral! mattor. These
experiments, together with viscosity tests on
raw and manufactured rubber, lead to the con-
clusion that the method employed in coagulat-
ing and treating the latex has a greater influence
on variations in the quality of plantation rubber
than any difference in the ages of the trees.

The Supplement to the Tropical Agriculturist
THE WATTLE BARK INDUSTRY
FOR CEYLON.
We direct attention to the letter of MrA J
Kellow which is prompted by a recent paragraph
on the subject of the wattle-bark industry of
Victoria in a commercial paper. We direct local
Government attention to the need for some real
enterprise in leasing, say, 1,000acre blocks of land
on the Uva patanas for an industry like this, If
such facilities were made known, there would pro-
bably be enterprising growers ready to take it
up. 100 percent. at the 8th year—even com-
pared with rubber—is attractive enough; and
this on a basis which is little above 50 per
cent, of the current range of prices in London
and Australia, a level that keeps fairly steady,
Albion, Nuwara Eliya, May 20th.
Dear %in,--The accompanying cutting, re
‘‘Wattle Bark,” contains much Interesting in-
formation :—
THe WartLe Bark INDUSTRY OF VICTORIA:
A Market 1n LonpDon,
The Master Tanners and feather Manufacturess of
Victoria haye not been able to comply with the condition
laid down by the Government that they should guarantee
a fixed price per ton for all wattle bark grown by the
Government during a term of years, in connection with the
Association’s request that the Government should provide
an adequate supply of home grown bark. The Association
has forwarded a letter to the Minister of Forests, stating
that while the members of the Association will always be
willing to pay the highest price of the day for all bark for
sale by the Government, they cannot guarantee any fixed
price, At present tanners are paying fancy prices for bark,
and many members of the Association have been compelled
to reduce their output of leather for export solely on
account of their inability to secure sufficient supplies of
wattle bark. The Association considers that its request
can be justified on sound business lines, as at £5 per ton it
pays the land owner handsomely to grew wattle bark, and
“there is practically, if not absolutely, no possibility of the
price ever again going below £6.” Itis further urged that
if in years to come, a3 a consequence of the planting of large
areas with wattle bark by the Victorian Government, the
supply should exceed the local demand, there will always
be a sure and profitable outlet for any surplus ia London,
where the present quotation for good Australian bark is
£1010s. The Association therefore reiterates its request
that the Government should largely increase the area of
its wattle plantations.
Considering the proved suitability of the upland
patanas for the growth of Acacia decurrens—
the variety producing the ‘‘ Wattle Bark” of
commerce—there is a wide field open for the
enterprise, if the Government could be brought
to see the desirability of encouraging the move-
ment, by either selling, or leasing, a few blocks
of 1,000 acres each, for the sole purpose of Wattle
cultivation, and thus bring more traffic to
that portion of the Railway referred to by Mr.
Ferguson at the last meeting of the Highland
Tea Coinpany, as follows :—
Mr Ferguson—said he would remember it when he went
back to Ceylon. With others he had been pointing
out to the Government the expense of the Haputale
extension of the Railway, which was bringing in little or
no traffic to the Government which had spent hundreds of
thousands on abeut 15 miles of Railway. They had said:
“Tf you cannot sell land, cannot you lease it on condition
that the buyers should plant a certain area with trees for
wind belts; and in that way you would get traffic for
the railway and not at all affect the rainfall or anything
of the kind,” (Hear, hear.) A few trees would even improve
the rainfall. It would keep the rain on the ground better
than patana.
and Magazine of the Ceylon Agricultural Society.
Many estates have already planted up Acacia
decurrens—first for wind belts, or fuel supply,
and latterly as a source of green manure. Occa-
sionally one hears of a consigument of a few
ewts. of bark to London, and because—as might
have been expected—the experiment has proved
a financial failure owing to the small quantity
sent in, the verdict has always been against it
as a possible paying ‘‘ege basket’; but any one
might as well send a few odd Ibs. of—say tea—
and expect to get its full value. What is wantod
is a regular supply in appreciable quantities.
In 1904, I wrote an essay (for the Tropical
Agriculturist) entitled ‘* Wattle Cultivation in
Ceylon,”—obtainable in pamphlet-form at the
Observer office—in which I endeavoured to show
what it might do if taken up ona sufliciently
large scale: with an estimate, based on actual
experience, of the quantity of bark procurablo
per tree; and taking £6 in Colombo as probable
value per ton, showing a profit of over 100 per
cent in the Sth year, whereas present quotation
is £10 10s per ton in London.

LOCUSTS ON LAWNS: A CURE.
May 21st.
Dear Srr,—A species of small locust or grass-
hopper is very destructive to lawns in the
Ceylon low-country. Most people, who take
pride in having a lawn in the garden, find these
pests most troublesome, and on the Colombo
Golf Links, L believe, they prove to be a great
pest. 1 send you this cutting, which I have had
by me for some time, and I feel sure it will be
found worth trial by the Ground-Secretary of
the Colombo Golf Club ; whileit is worth pub-
lication in the Tropical Agriculturist, as of use in
all countries where such locusts are troublesome:
What has come to be knownas the ‘Criddle mixture’ is
giving most satisfactory results in dealing with grasshop-
pers on the ranches of both the United States and Canada.
The mixture is composed of half a barrel of fresh horse
droppings in which is mixed a pound each of salt and
Paris green. If the horse droppings are not fresh the salt
is dissolved in water and mixed with the manure and
poison. When this mixture is scattered freely about where
the grasshoppers are abundant they seem to be attracted
to it, for they devourit readily and are poisoned thereby:
Dr. James Fletcher, Entomologist for the Dominion of
Canada, cites an instance where this mixture had been
scattered freely around the edges of a field, and states that
this particular field stood out as a green patch in a brown
plain, asit was situated in the midst of field where no-
thing had been done to destroy the grasshoppers, This
‘Criddle mixture’ now seems preferable to the poisoned
bran remedy thathas given, and still continues to give,
beneficial results, forit is less expensive than the latter
and less likely to poison other animal life.
The grasshopper in the States and Canada is
a species of Melanoplus; I do not know the
Ceylon species,—Yours truly,

PLANTING METHODS IN B.C. AFRICA.
Nyasaland, April 2nd.
DEAR Srr,—I see a letter in your issue of
January last, written from Mlanji and dated
lith November, criticising H. B.’s methods of
cultivation, &c, My reply to the gentleman who
sigus himself ‘‘ Planter’ is: ‘‘Would the power
the giftie gie us,” as Burns put it, to enable
‘+ Planter’ to see himself as others see him.
Your remarks, viz, that ‘‘ Planter” does not
want Ceylon men to come to Nyasaland is quite
true; but it would do him good and others too
to have a Job of Ceylon here, although there
might be the danger of ‘‘Planter” losing his billet
which is evidently the crux of his whole letter.
Plenty of men in this country have started
planting on less than even a few hundred
pounds of capital—with the assistance of the
Cottou Growers’ Association alone, and have
done well, too. Of course they had the land.
Ceara rubber has been in Nyasaland growing
like a weed in the bush for 20 years and more,
and many, who tried it, could not make it pay
any more than Ceylon planters did, and have
dug it out. New methods of tapping may yield
better results, but this remains to be proved.
**Planter’’ speaks of drink being the ruin of men
here (he might as well have mentioned drugs,
too); this takes place all the world over un-
fortunately. ‘‘Planter’ wants figures regarding
the yield of tea, &c. ‘There is no need for this
request seeing, as he says, he has been 5 years in
Mlanji, for he should be in a position to supply
them himself ; and I am sure all will be pleased
to see those tigures published.
A great drawback to this country is the want
of the experienced Visiting Agents system, the
same as exists in Ceylon.
Company Managers are the men who usually
visit and report on estates in Nyasaland and
their visits are made perhaps once in a year and
perhaps not for two years, so that Superinten-
dents of estates do absolutely as they please.
The result is reckless expenditure of public
money, as far as Companies are concerned,
I have known a man put in charge of an estate
here who, without consulting his neighbours,
raised the pay of ordinary labour to more than
twice the amount paid by others—for no reason
whatever except to impress upon the natives
that he was a big white man. Of course, the
money was not his own.
Unfortunately this throwing away of money
is not confined to new-comers, but to men who
have been in the planting line for a long time.
So itis not to be wondered at that ‘ Planter”
says £1,500 to £2,000 isrequired to start planting
in Nyasaland,
I have known men here start paying 3s. per
month, the usual rate for village labourers, and
keep these men on, raising their pay to 6s.
because they were too lazy to teach other men
pruning. How would Ceylon planters fare
if they were too lazy or indifferent to teach
thoir coolios pruning ? I guess they would get
their walking ticket,
592
A few hundred pounds would enable any man
to start in Nyasaland. The purchase of land or
lease is a mere trifle and the rest of his capital,
if employed to grow acrop of tobacco, he can
double in a year to 18 months’ time, getting
spot cash for the leaf from the Imperial To-
bacco Co. in Blantyre. Actual costof opening
100 acres of landin Nyasaland for coffee in 1898

There was no bungalow built, as the Superin-

year the yield of chillies planted between the
lines of coffee paid for all the expenses in con-
nection with the opening and left a handsome
prcfit to the owner. Noestimate is given for
the planting of chillies as they were simply
dibbled in and the cost was absorbed in the
other items of expenditure.
Labour is a trifle dearer now than it was in
1898, but the above estimate is near enough and
quite reliable. Of course the cost of opening
and bringing an estate in bearing may be any-
thing from £2 or £3 per acre to £20 or more en-
tirely depending on the man and his purse.
CRITIC.
CARBON BISULPHIDE ON ESTATES.
We received by a recent mail from home an en-
quiry on behalf of a manufacturer, in connection
with the rubber-growing industry, as to whether
and in what ways carbon bisulphide will, in fature,
be largely used on plantations. Onour enquiring
of Mr. M Kelway Bamber, that gentleman is good
enough to tell us that carbon bisulphide is
used for destroying white ants, and attempts
were made to have apparatus for its manufac-
ture erected in Ceylon and the Malay States.
It is very efficacious, but it is difficult to find
the nests of the ants in rubber clearings as they
are below the ground level or under tree stumps,
&c. Mr. Bamber, however, believes they can be
found if carefully looked for. About 1 or 2 oz.
of CS2 is poured into the nests and all exits
closed ; the vapour, being heavier than air, sinks
down through the nest, destroying the ants en-
tirely. ‘This was referred to by Mr. E V Carey
in our interview. If cheaply produced, its
use might be largely extended in tropical coun-
tries; but at present Shipping Companies do
not readily carry it even as deck cargo, owing
to its poisonous and explosive nature when the
vapour is mixed with air.
The Supplement to the Tropical Agriculturist
JAPANESE SYSTEM OF CHARCOAL
MANURE
is one which ought to interest all agricul-
turists, in the tropics as wellas elsewhere. We
direct attention, therefore, to the letter of the
Yokohama Nursery Co., which describes it and
the points in which it differs from a simpler sys-
tem it resembles. We shall be glad to hear the
experiences of any practical planter who takes
the method up, or meanwhile any criticisms of it
based on practical knowledge of manuring (tea
and rubber, especially) already acquired,
21-35 Nakamura, Yokohama, April 26th, 1909.
Dear S1r,—While questions of scientific
fertilisers are under discussion, it may not be
amiss to report what is doing here in Japan, in
that matter. We havea method known as the
“Oyaidzu system of charcoal manure” which is
highly recommended by Mr Ikeda Kenzo, the
president of Japan Agricultural Society, and is
now widely practised.
This is nothing but charcoal made ofstraw, or
any other combustible rubbish materials, mixed
with ordure or other manure which is claimed
to be very efficacious and produce good crops.
One-third is said to be sufficient for the purpose
as the charcoal resists against actions of weather
and retains power longer than any other way, such
washing away, blowixg off or evaporating, etc.
This may seem like the old way of ash _ utilisa-
tion, but what differs is how the charcoal is pre-
pared. Great care being taken not to allow the
material to burn but make it smoulder in a pit
by adding little by little slowly so as to keep
flames down yet the whole turn into charcoal with-
out any portion remaining unburnt. 80 per cent.
charcoal itis said can be made out of the material

THE BARRYDO TAPPING KNIFE.
We have received from Messrs Brown & David-
son a booklet regarding this new tapping knife
(GS Brown’s patent). This is thelatest inven-
tion in tapping knives, it is claimed, and its chief
feature is that recurrent expenditure is reduced
to a minimum. The neat blade with four cutting
‘edges can be reversed in a minute and the re-
maining sharp edges employed in whatever dir-
ection the operator is paring. It cuts right and
left hand, ‘‘ Puli or Push” without any altera-
tion or adjustment Itcannot possibly choke
aud requires no sharpening: itis the simplest
knife on the market. Requires no adjustment,

THE NORTHWAY TAPPING SYSTEM.
A SERIOUS DISCOVERY.
It will be remembered that about six months
ago there were rumours that anew system of
tapping rubber trees had been discovered, for
which there were claimed mary advantages over
the various styles of tapping then in vogue,
The inventor, Mr. Northway, supported by
experienced Ceylon planters, stated that it was
to be commended for simplicity in working, less
likelihood of damage to the tree and increased
work by the tappers, and these were among the
powerful reasons for giving the system an
exhaustive trial.
If there were no other reason, the fact that
our rubber estates in the future would, by the
new system, require 75 per cent less cooly labour
for tapping was in itself a sufficient justification
for the inventor’s clever idea being thoroughly
exploited ; and we believe that in many in-
stances the experiments, which have been macte
up-to-date, have realised expectations. We have
then learnt with more than ordinary regret that
the results of trial upon some properties have
disclosed drawbacks and disadvantages which
appear to imperil the future and assured
success of this mode of extracting rubber latex.
It appears that in certain trees which are
exceptionally rich in latex at this season of
the year the incisions caused by the pricker
close up prematurely, and before the flow
of latex from the cambium layer has
ceased, with the result that the latex flows
down the tree between the cambium layer
and the bark, where it formsa pad of coagu-
lated rubber, much resembling a rubber patch
which is used for repairing the inner tube of
a motor car tyre. This pad swells and causes
the bark of the tree to burst away, the pad
adhering firmly to the wood, which, with
the cambium, becomes discoloured and black,
and may prove the fore-runner of decomposi-
tion of the wood itself unless the pad of rubber
and the bark are carefully removed.
Perhaps the most peculiar phase of this state
of affairs is that these breakaways occur upon a
small percentage of trees, and those which are
particularly vigorous and robust and growing
upon rich, low-lying lands, where undoubtedly
the secretion of latex is much _ greater
than upon the hill sides. Wo may mention
that the trees on which this has taken place
were pricked about six weeks to two months ago
and it is only within the Jast three weeks that
these unfavourable symptoms have developed.
We sound this note of warning in order that
all rubber planters (and they are many), who
are experimenting with the Northway System,
may carefully watch their pricked trees ; and—if
they have discovered these danger spots of sub-
cortical pads of coagulated latex—take such re-
medial measures as they may consider necessary.
Should this unsatisfactory state of affairs mani-
fest itself generally, we fear that the Northway
system will stand self-condemned. The occur-
rence of these rubber accumulations under the
bark would suggest that for any but the slowest-
flowing latex-bearers there is the danger of the
(6)
593
latex not being able to flow sutticiently freely
through incisions made by the pricker and that
thesystem is therefore most suitable—or suitable
only ?—for the youngest trees, where a free flow
isnot yet fully established, or those few older
trees which promise never to give rich yields,
The wider incisions of the knife, which, with
subsequent paring, have given perfectly re-
newed bark, may well—after the above dis-
coveries—return again to a popularity which
had only been temporarily shaken.
In conclusion, in reply to Mr. Wiggin,
we are quite ready to learn; but the system
has not yet been tried nearly long enough
yet for even its warmest advocates to commit
themselves wholly either! And we under-
stand the possibility of mistakes through ex-
cess of zeal is less with the older systems than
with this new one that starts work on three
and four-year-old trees in Ceylon.
Lindula, May 24th,
Sir,—The coagulation of the orifice made by
the pricker and sequence as described by your
article can simply arise from one thing : in-
sufficient spraying—a result that must arise
without supervision, Does any one imagine
Ramasamy carrying and using water if he can
avoid it ? Why he would actually starve him-
self if he could exist without the trouble of
eating ? It is only hunger that makes self-exer-
tion evident. ‘To the present-day cooly work is
no pleasure. Neither, since Companies came into
existence, does he take any interest in his
estate as a domicile. Make and clear is the order
of the day as he sees the Agent is to sweat for
shareholders, so is his ‘‘make for himself.”
Take private properties now (there are some).
The life of the labour force thereon is an Eldo-
rado, No impossibilities forced on to the Super-
intendents. No impossible estimates to keep up
to,and only donein many instances at the expense
of the cooly. This isthe predominant factor
of the discontent and miserable state our labour
force has got into, want of sympathy and’ co-
operation. The Straits appear to have learnt
their lesson and labour seems to flow over there
freely enough. Here, Tempora mutantur et
nos mutamur in itis and not to our advantage
or welfare.—Yours, &c.,
EK. R. WIGGIN.

on the phenomenon referred to!]

Deviturai, Ambalangoda, May 25th.
Srr,—In reference to your article on a defect
alleged to result from the new tapping system,
I have not a single tree here that shows any
sigus whatever of any disease since [ started
new tapping. There is nothing new in pricking.
We have used prickers here for the last five years
and 50 per cent. of other estates have conti-
nuously used them for about that time.— Yours

Glendon, Neboda, May 28th.
Dear Sir,—I see in your leader in the
Observer of 22nd, mention is made of injury done
to rubber trees by the incisions of the pricker
closing up prematurely and causing the latex
to coagulate inside the tree and burst the bark.
Inoticed this some two years ago on a 15-year-
old tree growing on a Aili and tapped with an
ordinary knife and never pricked. | put it down
to tapping in February (avery dry month) and
when the leaves were off. However, it only
occurred in this one case and the bark was cut
away and subsequently healed up. Judging from
what has been written about the new tapping
system, it does not appear likely to supersede
aring though it may be suitable, in certain loca-
ities, for trees 3-4 years old.—Yours faithfully,
R. J. BOOTH.

Kalutara District, May 29th.
DrAR Sir,—The phenomenon, which has arisen
with the Northway system oftapping that you
refer to in your leader of the 22nd, I understand,
has only been noticed on old trees. It would be
interesting if you could get Mr Northway to
publish figuresin support of his statement that
equally good results, at less cost, can be ob-
talned by his new system, as by the one usually
in use. They should, I think, take the following
form ;—
(1) Quantity of rubber obtained in 1908 off a
specified group of trees, giving average girth,
number vofdays tappedand cost of tapping.
(2) Quantity secured this year, from same
group, by the newsystem (and anticipated yield
for year), with number of days tapping and cost.
Mr Northway should be easily able to provide
you with these figures and it would give other
users a line to go on and show them what can be
done. Itis, I think, important that the average
girth and approximate age of the trees should
be given.—I am, yours faithfully,
RUBBER-GROWER.,

In Repty to MR Wiecrn.
Ruanwella, May 31st, 1909.
Dear Sir,—fe Mr Wiggin'’s letters on the
New System of tapping, they are polite—to say
the least of it. He regrets the lack of brain
power in rubber planters tosee the damage done
by what he calls butcher's knives, but he seems
himself to lack the brains to see the damage
the blunt prickers can do.
He does not really understand (judging by
his letters)—the vascular system of the Hevea
tree; or he would understand the great often-
times hidden damage which is done to the tree
by the new system.
I would advise him to visit his friend Mr
Northway’s estate, or any other where the
tapping has been done for two months, and take
off a piece of the pricked cortex right to the
wood and then write to the papers the result.

There isa proverb which says; ‘‘ Don’t teach
your grandmother to suck eggs’’ ; and certainly
rubber tapping is not taught in Dimbula,
and I for one don’t consider that a visit now

rubber trees tapped, is sufficient to entitle Mr
Wiggin to teach his brother rubber-planters,—

RUBBER IN COLOMBIA.
The following curiousadvertisement appeared
the other day in the London Times :—
RUBBER PLANTATION.—Offer at 16s of 500 £1 fully-paid
Shares in dividend earning, old-established Company.
Capital £100,000. Estimated yield of rubber this year,
£12,000, increasing to £40,000 on further maturity of
plantations. |
An enquiry brought a letter to the following
purport :—
“ As requested we send you particulars of the 500 £1
fully paid shares in the Colombian Rubber Company
offered at 17s 6d or at 16s (£400 if taken in one lot.
The Company having now reached the dividend-earning
stage the most modern machinery for preparation of the
rubber was shipped to Colombia last December and
Mr. Sloan left early last month forthe estate to superin-
tend the preparation and consignment of from £10,000
to £12,000 worth of rubber part of the proceeds of
which will be applied to the payment of a first divi-
dend of 8 per cent or 10 per cent and concurrently with
its declaration application willbe made for a Stock Ex-
change settlement in the shares. On fuller development
of the resources of the estate and on erection of the
saw-mills the Company will be able to pay perma-
nent dividends of not less than 20 per cent, for rubber
can be produced on this estate at a lower cost (?d
per lb.) than in any other part of the world. We make
these statements on the authority of Mr. Jas. Stuart
Sloan, the Managing Director, who himself holds 30,000 -
shares and if you enquire through your own Bank of
Mr. Sloan’s Bankers the Societe Generale, 53, Old Broad
Street, as regards this gentleman’s commercial status
and reputation you will find that confidence can be re-
posed in the success of any enterprise which he directs.”
A pamphlet accompanying the letter gave in-
teresting particulars (and illustrations) of the
estates belonging to the
CoLomBiAN RuBBER Co., LTD.,
on the Pacific Coast of the Republic of that
name, 2 degrees north of the equator and
midway between two ports, total area being
168,000 acres, held under 99 years’ lease.
Forest land covers 150,000 acres with wild
rubber trees (Castilloa Elastica and Sapium)
averaging five to the acre, which are ex-
pected to be tapped gradually and to give
5 1b. rubber per tree. There is said to be £10,000
to £12,000 of rubber ready for shipment, and
I must say the growth of castilloa trees in an
avenue, eight years old, shown in one engraving
is very good indeed. The investment ought,
therefore, to be a promising one for any
person caring to invest in South America. Alto-
gether 105,731 castilloa trees have been planted
and are from 1 to 8 years old. Manioc,
banana (a crop every 8 months), but are used to
shade the young rubber trees; also Abaca, a
new product, yielding a fibre like Manilla hemp ;
Mahogany trees are common in the forest.
The Colombian Government is so anxious to
have cotton, coffee, tobacco and rubber pro-
duced, that up to July, 1914, they offer a pre-
mium of 4s per 100lb. of each of the first three
and 16s per 1001b. of plantation rubber. The
profit for the first year is estimated at £28,770,
so it is difficult to see why shares should haye
to be offered at 3 discount,

’ THE FUTURE OF PARA RUBBER IN
THE AMAZON DISTRICT.
We direct attention to the article which we
here reproduce. Mr. Sandmann, the writer,
was sent out by the German Colonial Office to
the East in 1906 and to Brazil in 1907 to study
the rubber industry. In the September num-
ber of the Zropenpflanzer a long abstract of
his official report appeared, and Dr. 8. H.
Berkhout replied to this in the Febrnary
number. The tenor of Dr. Berkhout’s paper was
to show the difficulties Brazil has to encoun-
ter in producing rubber, and her inability to
compete as regards cost of production with the
East. He concluded: ‘‘Just as South America
failed in the competition against cultivated
- cinchona, 80 will its wildrubber be unable to
hold out against the plantation article.” It
will be seen from Mr. Sandmann’s reply that
he differs from Dr. Berkhout considerably.
An article with the above heading from the
en of Mr. D. Sandmann appeared in the
ropenpflanzer for April. Mr. W. J. Gallagher,
M.A., has kindly translated and annotated it
for us as follows :—
WILD v. PLANTATION,
“ Before I had visited the Amazon District
I was of the same opinion as Dr. Berkhout,
and. in my report on the rubber; industry in
Ceylon I expressed the view that it will be
impossible for the collection of rubber in the
primitive forests to compete with Plantations,
Dr. Berkhout built on a very certain found-
ation when he assumed tho conditions im
Surinam (Dutch Guiana) to be similar to those
in the Amazon region. I have reached an
opposite conviction, although [ have never
been to Surinam, but have been informed of the
local conditions from Huropeans resident there
for many years, Hspecialiy do the political, clim-
atic, and agricultural conditions differ consider-
ably from those in the Amazon. ‘Dr. Berk-
hout says: ‘In the future it will be absolutely
necessary for the owners of cultivated rubber
for the production from Brazil to decline.’
I am of acontrary opinion though admittedly,
with a much larger amount of rubber thrown
on the world’s market, the present high prices, |
which give profits far beyond the normal, will
not be reached. With cheaper prices suflicient
to give well-cultivated plantations a normal
profit so many new applications of rubber would
arise that not only the present production of
70,000 tons but even several hundred thousand
tons per annum would be consumed, The main-
tenance of the Brazilian output isa danger only
to estates which produce their rubber dear and
of poor quality.
‘Dr. Berkhout agrees with mo that1 kilo
(2.1/5 lb.) of rubber can be produced easily on
an estate for 2 marks (2 shillings).” [This is
equivalent to 11d per Ib. At least one estate has
to my knowledge laid rubber down in London
at this outlay. Apparently the cost f.o.b. at
the nearest port is meant. Inthe F.M.8. this
varies from slightly under 10d to over 13d. The
higher figures refer to estates producing
595
small quantities, and are of little value for
purpose of comparison.—W. J. G.] ‘‘When
Dr. Berkhout states that the cost of production
at the present day in the Amazon area is 5 marks
per kilo (2s 33d per lb.) 1 must emphasise, as I
didin my report, that these 5 marks are not
money in the German sense of the word, but re-
present so much provisions and implements of
production which at the present time possess so
high a nominal value in the rubber producing
areas, but which under changed conditions, es+
pecially if produced locally, would fall consider-
ably. There isno ground for doubting that the
provisions and luxuries consumed in the Amazon
area could easily be produced there. Indeed the
soil and climate are such that these articles of
consumption could be produced more quickly
and easily there than in most other regions.
‘‘In the present prices of rubber labour
is paid so high that all cultivation of food
products is left aside. After four to six
months’ work of a 6 to 7 hour day, a tapper
is able, notwithstanding the high price of neces-
sities, to support himself, and with carefulness
he can even eave something. This is also the
reason why the emigrants from Ceara will not
go, as Dr. Berkhout thinks they must in the
future, to districts in South Brazil where, to
support themselves, they must work not 6 to 7
hours a day for four to six months, but a 10-
hour cay the whole year round. Further, the
Ceara people profer the free life in the forest to
that onthe estates (cocoa and coffee) of Sao
Paulo or Pernambuco.
‘* With the
PRODUCTION OF FOOD CROPS
in the Amazon region the conditions will imme-
diately change, because not only the male
labourers but their families also will immigrate
there. This would not alone lower the cost of the
journey but the working strength would be con-
siderably increased. Besides, the Seringuero
(rubber-tapper) has no yearning after big towns,
If the Ceara natives who immigrate to the
Amazon district worked their day of 6 to 7 hours
the year round, instead of for 4 to 6 months as
they do now, the production would be certain,
and the workers would still have shorter hours
inthe pleasanter Amazon area (pleasanter to
them) than on the estates of South Brazil,
‘*To decide the question it is necessary to
have studied the habits of these people on the
spot. Only when one has convinced himself how
satisfied with his life the Seringuero is, and how
he sees the dolce far mente as the greatest object
of his labours, can one understand that only
necessity will make him work more.
‘‘The variations in the quantity of rubber
exported annually also confirm this. I agree
with Dr. Berkhout that only in the following
year does a fall in price have an effect on the
production. When the price for years steadily
fell from 48 3d and in 1902 reached its lowest
at 3s 2d, only then did the Seringueros, when
need compelled them, do more work ; and the
expression of this is found inthe export of the
year 1903 with 31,094 tons against 25,430 in 1899,
‘‘T have already shown in my report (abs-
tracted in Tropenpflanzer in September, 1908)
596
that the production of food in the Amazon
district would reduce the present cost of collec-
ting and preparing 1 kilo of rubber from 5 marks
(=5 shillings) to 1°60 marks (=1s 7d.)
‘* A comparison of the returns in rubber
from a hektar (=22-5 acres) compared with
those from the same area on an estate is
not possible. The value of a hektar of
primitive forest to that of an estate often
is as 1 to 1,000. Large areas of primitive
forest can at the present day be obtained
in the Amazon region for one marka hectar,
that is for the cost of the measuring only.
Beside rubber the Brazilian forests yield many
other valuable products. Dr. Berkhout is in
error when he thinks that, because “Terra firma”
(the area which is not flooded when the river is
at its height) is often far from the banks ofa
river, it must likewise be far from the areas
where the rubber is collected. It is true that
the areas which Hevea prefers are not always
bordering the ‘‘Terra firma,’ but the suitable
land for the raising of foodstuffs is exactly the
‘Terra firma,” and it can be cultivated when the
flooded areas cannot be worked.
‘So long as rubber brings a high price, no one
thinks of improving anything, but
WITH A FALLING PRICE
the need for improvement and better work would
make itself felt and would be met.
“The Brazilian Government compared with
the Colonies of England, Holland and other
countries has yet done little, it is true, in
the way of experiment stations and the like to
improve land industries, though even here it
cannot be denied that Brazilis making progress.
“Dr. Berkhout’s view that a decline in the
price of rubber will lead the people to plant
cocoa and other cultivations is to be accepted
conditionally. If through high cost of living and
dear labour the exploitation of rubber muststop,
so will the cocoa estates, etc., inthe Amazon
region with equivalent rates of labour pay be
just 2s little able to withstand the cocoa, etc.,
estates of Asia and Africa.
“The comparison withthe cinchona industry
of Java, which defeated that of Bolivia, would be
applicable only if the poorly remunerative cin-
chona of the Bolivian forests was comparable to
the highly remunerative rubber of Brazil. Ifa
better paid and more easily worked product than
rubber was available in the Amazon, the natives
would turn to it from the rubber industry, But
as long as no easier way of making a livelihood
is possible, the natives ofthe Amazon area must
give their attention to rubber.”
‘*T must still maintain my conviction that the
production of rubber in the Amazon region will
be a thing to reckon with in competition when
the plantation areas are in full bearing. It is
on this account necessary to consider, before
opening up new estates, how far these will be
capable of yielding a profit in the competition
in production and price with Brazil."
It is interesting to note in the foregoing that
a fall in the price of rubber, within limits
of course, will increase the Brazilian output,
and further the latent capabilities of even the
present labour force,—Matay Mat, May 20,
The Supplement to the Tropical Agriculturist
THE CONSERVATION OF LAND
AND WATER.
A large proportion of the rain, which falls on
the land, is practically lost to the cultivator by
its flowing over instead of into the soil, But
apart from this there is a far greater loss due to
erosion, which is responsible for carrying away
immense quantities of soil material, partly
in solution, but chiefly in suspension. The value
of this loss is not easy to compute, but it will
be readily admitted that it must be very great
when it 1s recognised that the wash consists of
surface soil which is the richest part of it—being,
indeed, the ‘‘cream” of the land. The opening up
of new lands and the exposure of new surfaces, to
the action of falling and running water goes to
increase this loss. When rain falls, a part of it
evaporates directly, a part flows away and joins
the streams to finally find its way to the sea, a
part soaks in to the soil and sub-soil either to
emerge as springs, &c., or remains underneath
the surface to serve the requirements of plants if
it is not allowed to be drawn up and evaporated.
The amount of water which runs off depends
on the slope of the land and the nature of the
growthupon it. Forest vegetation, a close growth
of grass, on a deep friable soil, will so check or
absorb the flow that there will bea minimum of
loss of moisture to the soil. The chief scurce of
our prosperity as a colony is the soil; it is the
duty of the Government to encourage the con-
servation of the soil and its improvement for the -
immediate benefit of the planter and native cul-
tivator, and the ultimate welfare of the Colony.
The most valuable asset to the agriculturist is
the water that falls on the land and permeates
the soil where it can aid in the production of
crops. It is, therefore, also to the interest of the
Government to see that this water shall be so
controlled and conserved as to yield the greatest
benefits to the cultivator of the land and even-
tually to the whole colony.
It is on cultivated land, however, that the
evils of soil erosion begin ; while it is clear,
therefore, that the remedy must begin on these
areas, it is the duty of Government to see that
the remedy is prescribed and applied. The
course to be adopted is in some particulars at
least quite evident :—
a. Deep cultivation and good tilth on culti-
vated areas. By this means the maximum of rain-
fall will be absorbed and the minimum allowed
to run off the surface. This treatment of the
land will, moreover, be an advantage in other
respects, inasmuch as it will assist in drawing
up plant food to within the reach of the shorter
rootlets and also carry down humus to feed the
deeper roots.
6. Deep underground drainage (preferably tile
drainage) on flat lands and tenacious soils where
the ground water moves sluggishly. This mode
of drainage is little known and less practised in
the East, but under the conditions referred to
its action is most important in helping both soil
and subsoil to crumble and disintegrate and
through the mechanical and chemical changes
and Magazine uf the Ceylon Agricultural Society.
induced to become friable and susceptible of
retaining the right amount of moisture for
plant growth. The indirect result, however,
is the reduction of surface flow and erosion
when rain falls.
¢. Contour Cultivation on Rolling Lands.—
The plough-furrow (where ploughing is done)
and crop rows should be carried round the slopes
in such a manner that each furrow or row will
lie level, so that there will be no tendency
for them to be widened into gullies by storm
water, but rather to close runnels and form
receptacles in which water may lodge till
soaked into the soil.
d. Inhilly land contour cultivation should
be supplemented by ‘‘ balks” or ‘* breaks,” i.¢.,
strips of grass separating cultivated stretches,
and these should be level like the cultivated
portions. The tendency would thus be towards
the formation of a series of terraces.
e. On very steep land it is. advisable that
agriculture should give place to silviculture
which might be combined with grazing.
On mountain heights, forests should be
retained and extended, for, as the Spanish say,
the mountains are the mothers of waters, and
every lofty range being a ‘‘ Sierra Madre,” and
the forest trees acting as distributing agents,
and reducing erosion and wash to a minimum,
It would appear from what has been said that a
scheme of classification is desirable, so that lands
of different elevation and situation may have each
the most suitable crops assigned to it—whether
timber, grass, shrubs, grain crops and so on.
But to carry outa policy such as is here indi-
cated, individual and collective action is neces-
sary. For educative purposes it is necessary that
information should be widely diffused as to the
magnitude of the loss by erosion, the facility
with which it could be checked, and the cer-
tainty that the result will be profitable to each
individual while serving the general weal. In-
dividual action could, of course, be confined
chiefly to improved methods of cultivation, as
indicated above, with a view to conserving
both soil and moisture, while more extensive
operations with the same object in view can
only be carried out by co-operation,
The evils resulting from the neglect of the
course prescribed is amply exemplified in this
colony, where, indeed, afresh source of trouble
has arisen through the damage done by the
silting of paddy fields.
The duty before the agriculturist as well as
the Government is clear, and we trust that we
have, to some extent, succeeded in arresting
their attention and proving the necessity for
conserving soil and moisture by every means
in their power.
CULTIVATION OF THE SOIL.
With reference to the subject of the ‘‘culti-
vation” of the soil and the very useful letter of
“Delta” in the Tropical Agriculturist, in
drought-affected areas, and more especially
where the soil is very stiff, as on either bank
of the Deduruoya, where the soil is chiefly
alluvial, too much time and money cannot be
expended in keeping the surface soil in a fine
state of tilth. The suggestion is unpractical
to stir the surface soil after every period of
597
rain, though, of course, it will be very bene-
ficial. The least coconut planters with a stiff
soil to work could do, is to thoroughly
plough or till the soil one year, and in the
following year harrow it, or break the clods
thoroughly with mamoties, On a free, sandy
soil, the latter operation is not an absolute
necessity, as the surface soil does not cake.
On estates that I know of on either bank of the
Deduruoya the growth of grass is so rank that
aeration of the soil, so necessary tu improve
its mechanical and chemical condition, cannot
take place. My advice has always been to
turn over the surface soil, which will mean
green manuring as well, though not with the
now fashionable Leguminosz, and to lime it.
This latter treatment will not only convert the
luxuriant herbage into humus, but will set free
all the latent and dormant elements of fertility
in such soils, and will also improve its mechani-
cal condition. Those with a book learning of
Acricultural Chemistry say ‘*‘Do uot lime the soil
oftener than once in 3 or 4 years, as it exhausts
the soil.” This is, of course, true where enor-
mous quantities of lime are used. My advice
has been to lime after ploughing every alternate
year with moderate quantities ofit. The rich
growth of grass that will follow should be wee-
ded with mamoties in the dry weather, when
other works are not possible, and the grass be
allowed to remain on the surface to act asa
mulch. The weeding will also stir the surface
soil and make that too act as a mulch.

The topic of the utmost interest in the India-
rubber industry today, and that which is most
considered, is the present and prospective price
of crude rubber, Whether the manufacturer
be located at Malden, Manchester, Mannheim,
Melbourne, Menin, Milan, Mjondalen, Montar-
gis, Montreal, or Moscow, the question is ever
present, as one which must be take into account
in planning every detail for the future, This is
a fact which makes the whole rubber industry
akin, for the price of rubber everywhere at any
moment practically is the same, while the same
uncertainty exists as to what the price may be
tomorrow. The producers of rubber and the
traders in rubber have troubles of their own in
relation to the same subject, but here we shall
treat more particularly of the manufacturers,
Where rubber prices are made, or how they are
made, are questions not now ‘pertinent to our
purpose. The uncertainty of prices is the thing,
and what the consumer of rubber can do about
it. Low priced rubber is not so essential.
When every consumer of a given grade of
rubber must buy it practically from the same
source, and it costs them all precisely the
same figure, they are all on the same footing.
Whether the cost is 50 cents or $1 a pound, or
more, would be immaterial—if permanent prices
could becounted upon. But they cannot. The
average price at New York of fine up-river Para
rubber during the year 1902 was 76 cents;
during 1905 it was $1°284; since then it has been
less, the figure for 1908 declining to 93} cents.
This year, so far, the price for this grade has
kept in the neighbourhood of $1°20, hen itis
598
considered that the difference between the
highest and lowest year prices here quoted
amount to no less than $1,157:42 cents per
metrical ton, and that these fluctuations usually
occur without warning, the buying of raw
rubber by consumers approaches almost a
speculative basis. The producers of rubber in
the Amazon region, far from satisiied witha
condition under which they have no say in
fixing the market price of their produce,
have determined upon a course of action,
in which, with the help of the government
and of a_ great bank, they mean to
hold their rubber whenever prices are
not high enough to be attractive. Now the
holding of rubber anywhere is an expensive
practice, when storage costs are considered,
insurance, interest on advances—and the ine-
vitable shrinkage in weight. Itis well enough
to speak of rubber as being a modern neces-
sity, but there are limits to what people will
pay, even for necessities, and manufacturers
would have to halt somewhere in the matter
of paying advancing rates on rubber, even were
the Amazon region the world’s only source.
There would be an inevitable check to rising
prices, due to increased production and the
hesitation of consumers to buy, after which
the banks would have to unload, with such
results as followed Vianna’s state aided rub-
ber ‘‘ corner ”—a fall to half the former prices
aud loss to everybody concerned. The India
Rubber World, a dozen years ago, printed an
article on ‘‘ What Vianna Did for African Rub-
bers,” showing that his speculative ‘ bearing ”
of the market for Para rubber opened the way
largely for the increased use of African grades.
Nowadays, African rubbers having won an
established position in the industry, though
now apparently falling off in the rate of pro-
duction, an important new source of supplies
has been developed—the Eastern plantations,
the product of which (Hevea) is better cal-
culated than even the best Africans for sup-
planting the Amazon rubber in the industry.
Without meaning to advise our friends on the
Amazon, it would seem that their best interest
lies, not in forcing up prices to an artificial
level, but to so improving their business
methods as to enable them to sell at
a profit at even lower prices than at present.
Their devotion to any policy gives the plan-
ters of Ceylon aud Malaya, backed by un-
limited European capital, the very encourage-
ment which they want and most need. The
Eastern planters have it in their power
to appeal strongly to the consuming markets
in the matter of guaranteeing prices for longer
periods than have ever been known in the
trade before, and we shall be surprised if this
does not strengthen the demand for their pro-
duct,—Jndia Rubber World, May 1.

INTERPLANTING RUBBER WITH
COFFEE.
Dr. Cramer, an agricultural expert has de-
livered a lecture to a gathering of planters at
Serdang, in Deli, on linking coffee growing
with rubber cultivation. He dwelt on the
Robusta variety of coffee, which is being
The Supplement to the Tropical Agriculturist
favoured by plantersin Java. The point was
made that, in Europe. Robusta coffee fetched
as good prices as the Santos variety from
Brazil. In his opinion a_ large stretch of
country in Kast Sumatra is admirably adapted
for Robusta coffee as a catch crop on runeee
estates. —Straits Times, May 28.
TAPPING YIELDS.
Mucu LArGerR BY THE OLD METHOD.
Mr W H P Dias, of Wawulugala, Horana,
writes to the local ‘‘Times” of the relative results
obtained on that estate from 225 trees of 5-year-
old rubber tapped in the old half-spiral method
of paring, and 225 trees of the same size, age,
and in the same field tapped by the Northway
prickling system :—
““] began tapping by the Northway system
on the 17th of April. To this date I had secured
63 lb of dry rubber from the 225 trees I marked
off in January and tapped for 47 days by half-
ee system. Below I give the results in tabu-
ar form :—

of the bark left on the side I have tapped, and
there is the possibility of my securing more than
110 lb of rubber trom the remaining bark on
this side. Whatever it is, I am certainto obtain
220 lb of dry rubber from these 225 trees for this
year. Whereas from the trees tapped by the
Northway system, I have secured only 20 lb of
dry rubber, and [ may obtain another 20 lb at
the most for the other 30 tappable days in the
year which will make 401b for the year. Of
course, these trees were not manured year after
year like Mr Northway’s. Last week I went
round, passing several well-known estates at
Neboda and Tebuwana, the centre of rubber,
and I found that many had taken to the North-
way system, but that now most of them were
giving itup. So I am convinced of what Mr
Harrison says; it is safer to walk on known
ground than try to flyin unknown places.

A FRENCH ESTIMATE OF PLAN-
TATION RUBBER.
The conclusion reached by M. Edouard Payen,
in an article on rubber which he contributes
tothe Heonomiste Frangais, is that the present
situation is not permanent, and that itis pro-
hable that in ten years’ time it will be necessary
tu turn towards the plantations of the Far Kast
when we wish to foresee the state of the rubber
market, instead of to Brazil and Africa, as is
the case today. Itis almost certain now that
there is no lack of thisarticle to fear; but if,
on this side, security is obtained, it is lostin
the countries for which the exploitation of the
wild rubber is a source of riches. These
countries must prepare themselves, while there
is yet time, to support without too much
inconvenience and hardship the consequences
of the competition of plantation rubber. The
writer mentions that Professor Perrot, of the
Ecole de Pharmacie of Paris, recently esti-
mated the land under rubber in the Far East
as follows:—Malaya, 186,000 acres; Ceylon,
182,000 ; Java, 60,000; Sumatra, 32,000; Borneo
and New Guinea, 10,000 ; India and Burmah,
30,000 acres. Specialists think that if, about
1916, the Far East produces 15,000 tons of
rubber, planters should count themselves very
fortunate,— Ld ( Express, May 14.
COPRA FROM THE DUTCH EAST
INDIES.
The British Consul at Amsterdam, reporting
on the trade of that neighbourhood, remarks :
—Copra has sprung into prominence in the
Netherlands in recent years. The Notherlands
consumed in 1908 about one-sixth of the world’s
production, much of which comes from the
Dutch East Indies, Most of the copra for the
Dutch market comes to Amsterdam, where it is
manufactured into various kinds of oils, edible as
wellas for the manufacture of soap. In 1906,
1907, and 1908 the following quantities were
imported into the Netherlands: 47,689, 52,632
aod 71,432 tons respectively, of which the share
of Amsterdam was 38.867, 46,744and 57,702 tons
respectively. Great care istakenin the Dutch |
East Indies to secure a fine quality of copra, as
it is only from the finest qualities that the best
edible fats derived from this source can be pro-
duced, Small crops are anticipated for 1909.
During 1908 the average price for Java copra
was £1 148 4d per bale of 220 Ib LL GC. BHa-
press, May 14,
JAVA GCOPRA
is fast losing its good name in the market
owing to careless methods of preparation. The
Chamber of Commerce at Samarang has urged
the Java Government to take action by ins-
pecting all copra prepared for foreign markets,
so that only the certified article shall be ex-
ported. The Chamber has drafted a bill for the
purpose which is now under the consideration
of the Government. Java copra hasa high re-
putation from being mostly dried in the sun,
599
and not artificially. But now fire-drying has
become so common that the time is approach-
ing when Java copra can no longer be marketed
as fair, merchantable sun-dried. There is danger
of its being classitied low as fair merchantable,
or fair merchantable, kiln-dried. Further dis-
favour has fallen upon the article by preparing
it from unripe coconuts.—Straits Times, May 28,
SOUTH CAROLINA TEA.
Mr Consul Donnelly, reporting on the Con-
sular district of Savannah, says:—...Tea, which
was for a long time considered one of the pro-
ducts peculiar to the Far Kast, is now accepted
as fully naturalised in the south, and it is stated
by those interested in the matter that South
Carolina tea will soon be as well known to
drinkers of this beverage as is the best leaf of
Formosa or Japan. The South Carolina teas
that seem to thrive best are of the better varie-
ties, and teas grown in this State can now be
bought at one dol (4s 2d) per lb, which are said
to compare favourably with good grades of im-
ported China, Japan or Formosa teas in flavour,
quality and price. Good foreign teas cost in
this country as much as 1 dol or more per lb.
South Carolina tea could not compete in price
with much of the cheaper importations. The
majority of the people here are not tea drinkers
—cotiee being the favourite beverage, but there
seems to be a change taking place in this re-
spect.—Financier, May 1.
A BiG CROP OF COCONUTS.
A paragraph in an F, M. 8, Contemporary
states that there is on Klanang Estate a coconut
tree which had upon it a short time ago 360 nuts.
Though it has not quite so many at present, the
tree is still a very remarkable sight. Not only is
it literally loaded with large nuts, but a number
of small ones are to be seen in the earlier
stages of development. Curiously enough the
tree is by no means a large one, and is only
about eleven years old.
PRUNING ORANGE TREES,
‘Orange Tree” asks :—Do orange trees require
pruning? Ifso, state to what extent.
The answer to this question might be ‘‘Yes” or
‘“No,” but to be more definite I would say that
anyone who requires to ask the question will be
well advised to let his trees alone, for he is more
likely to do harm by pruning as the word in
generally understood than by allowing nature tu
take her course. You give me no idea as to
whether you are referring to old or young trees,
but it may be worth whiie indicating in a general
way the principles which should guide the owner
of an orange tree in his treatment.
We will suppose that you are referring to young
trees just planted. Contrary to the generally
accepted ideas [ believe that it is as important
to cut orange trees hard back at the time of plan-
ting as it fs to so treat apples, pears, and other
deciduous fruit trees, and for the sam) reason,
te oe
’
if
600
hen the tree is taken from the nursery its roots
ae mutilated and probably at least four-fifths of
them and possibly much more have been cutaway
by the spade. lt is, therefore, wise to remove a
corresponding portion of the top, and personally
when planting a young tree 1 would invariably
eut it back to short spurs of from 3 to 8 inches
long and remove the majority of the small twigs.
When a tree so treated, or indeed if it has
not been so treated, starts to grow, it will
be found to almost imvariably put out a great
number of buds. If all these are left, they
result in small spindly growths, and the proper
plan is to rub off all but those that are
required when they are from half-an-inch to
two inches long. If my advice is followed and
the young tree is cut hard back, you will only
require to allow from 3 to_6 shoots to grow. | If
one cr two of these begin to make eXCesB1VE
growth ahead of the others, 1t 1s advisable to
nip vut the tender tops to allow the develop-
meut of those that are less strong. Any shoots
which put out from the trunk of the tree below
where it branches should be rubbed off as soon
as they appear.
In the second year’s growth you will generally
find that from the ends of the previous years
shoots from three to slx buds start, and the
proper treatment is to remove all but one or two.
If this plan be followed no pruning as generally
understood will be required for many years.
In the case of older trees all the pruning re-
quired is to remove any weak and spindly wood,
any shoots that seem to be diseased or dying,
anc to generally thin out the tree just sufficiently
to allow light and air to pass right through it.
If you will take notice of old trees which have
not been thinned in this way you will find that,
although they may be perfectly healthy, they are
so dense that all the inner twigs are spindly
and of poor colour and practically all the fruit is
borne on the outside of the tree exposed to the
light. If a tree is kept open in the way I have
indicated this will not be the case, and the fruit
will be distributed throughout the tree. This
results ina bigger maximum crop and better
development of the fruit. —Western Mail, May 22.
TEA IN THE ANDAMANS.
ay not be generally known that tea is
as as a small scale at the Andamans, where
160 acres were placed under this crop in 1907-08,
and the outturn of the finished product amounted
to 41,605 lb, against 60,290 lb. in the preced-
ing year, which was a record, or nearly 376 1b,
per acre. The decrease is attributed to the un-
favourable weather. Itis, however, not quite
clear why this tea gardenis maintained, because
it was worked at a loss of R17,808. If the tea
garden were self-supporting, even though there
were no profits, there might be some extenuation
for its upkeep. The greater portion of the out-
turn was supplied to the Supply and Transport
Department, and 3,423 Jb. was sold locally, to
the former at 0-5-3 and to the latter at 0-4-0 per
Ib. There is also a coffee garden in the Settle-
ment which has been leased to a contractor for
R750 per annum.—Madras Times, pee 31.

The Supplement to the Tropical Agriculturist
A SUGAR-CANE FACTORY,
In SoutH Arcot,
It is stated that a Company will shortly be
floated with a capital of R1,35,000, for for-
ming a sugar-cane plantation of about 450
acres in extent at Valavanur, in Villipuram
Taluq, South Arcot, the intention being to
work it on up-to-date scientific methods, under
the management of a specialist, as is done
in Java, and to erect a small factory with the
necessary plant for dealing with the produce
of 100 acres and converting it into refined
sugar. For the plantation purposes an outlay of
about R60,000, inclusive of the cost of the land,
irrigation appliances, etc., is contemplated,
with an annual expenditure for upkeep of
about R15,000 for 100 acres cultivated. The
cost of building a Sugar Factory, and provi-
ding it with the necessary machinery is esti-
mated at R60,000. The average cost of gro-
wing cane locally works out at R90 per acre,
and the receipts average, on the basis of the
price of R2) per candy of jaggery, R250 an
acre. On the Government Farm, at Palur,
however, and on Messrs. Parry & Co.’s Farm
near their Nellikuppam Factory, the annual
expense is said to be about R120, and the
yield about R450, an acre. The ryots, who
have been able to put up the bullock-driven
crushers supplied by some Madras firms, are
said to be able to realise, after meeting the
expenses of jaggery-making, a net profit of
R25 per candy of jaggery,
Taking, however, the lower yield of R250 an ~
acre, the receipts from 100 acres would amount
to R25,000, while in the remaining area belong-
ing to the Company local crops can be raised
to the ordinary yields obtained. The cane from
100 acres (6,000 cart-loads of 3,000 tons, worth
R25,000, as abve shown) is calculated as a re-
sult of actual experience to yield 200 tons of
sugar wortha 217 a ton, z.e., R43,400, and 100
tons of molasses worth R54 a ton, 7.e., R5,400.
The expenses of manufacture amount to
R8,200 at R41 a ton of sugar, and allowances for
depreciation of machinery, building, etc., at 10
per cent. of their value, would come to R6,000.
There would be then from sugar manufacture
alone a profit of R9,600. This, with the R25,000,
the value of the cane raised on the lands,
brings up the total income from the plantation
and the factory to R384,60C, which, on the
capital of R1,35,000, means a return of 25 percent.
That there is a very wide field for sugar in-
dustry in this country is admitted, asthe imports
of sugar from Java, Germany, Austria, etc., are
steadily increasing ; and with a view to deve-
loping the industry, the Government, at the
Industrial Conference held at Ootacamund last
year, expressed their willingness to give all
possible encouragement to promoters of the
sugar industry. The enterprise being shown
in this connection by certain Hindu gentle-
men of Valavanur, which has hitherto been
famous rather as a ground-nut growing and
trading centre, is very much to be commended;
and everyone will |wish the promoters such a
measure of success thatit will lead to many
other similar undertakings being established.

THE RICE-BUG OR PADDY FLY.
‘He rice-bug is the same insect that in Ceylon is known as the paddy fly, and causes great damaye
to local crops. Indeed, the necessity for rigid observance of seasons in paddy cultivation is chiefly
due to the attack of fly which an out-of-season crop is invariably subjected to. An Indian report
(by Mr. H. Maxwell-Lefroy, the Imperial Entomologist) contains a very full account of the pest, its
distribution, habits, and life history, as well as the method of combating it ; and the information given
below is mainly abstracted from that report.
The scientific name of the rice-bug is Leptocorisa varicornis, and the genus is believed to include
three species ; but the points of distinction are very slight, and probably do not imply any difference in
life history. The bug is commonly found in long grass and thick vegetation, being present here singly.
It is only at special times and on special crops. such as paddy, that it occurs gregariously. The morning
and evening are its most active periods, and during the hot part of the day it goes deep into shelter. As
all who are familiar with the insect know, it is coloured green, and associated with an objectionable odour,
being hence sometimes called the “Green bug.”’ Its normal food is the sap of flowering shoots of grasses.
When infesting paddy, it feeds on the tender developing grain. which is full of milky sap. The dark
brown eggs are laid on leaves in clusters or rows, and number from twenty-four to thirty. They are
protected by a gummy substance, which helps to attach them to leaves and prevents their being washed
away byrain. The eggs take from six to eight days to hatch out. Between hatching and maturity the
nymph passes through five stages, occupying, say, about eighteen days, during which time the wings
are gradually developed. It is not exactly known how long the imago, or fully developed insect, lives,
but insects have been kept alive in captivation for three months. The following is an actual record :
Eggs hatched on September ~, adults reared on 18th, and lived until November 2. Of enemies to the
rice-bug, there are two known: Cicindela seepuncta, Lin, which is abundant in rice fields in India from
August to October. This is a flying insect and destroys the rice-bug in numbers. Another is an egg
parasite, which has not been described as yet. Ordinarily, the bug occupies « life cyele of from tour
to five weeks in warm weather, breeds freely with the rains, and feeds on rice, dry grain, and grass.
There are apparently five broods, depending, however, on local conditions, food supply, &c. With
cool weather the insect leaves the open field and goes into the denser shelter of uncultivated land.
There is nothing to show that it breeds again till the following rains.
We now come to the most practical part of the circular, namely, that referring to treatment.
(1) There is the treatment resting upon superstition, and consisting of “‘ mantras”: or charms. This
may be put down as utterly useless. (2) Smoking by burning aromatic herbs and resinous substances
to windward. This is only a temporary remedy and, though useful in saving individual fields, merely
shifts the enemy. (3) Ropes saturated with resin or kerosine or fish oil are drawn over the fields so as
to brush against the ears of paddy. This is rather more effectual than the last. (4) A paddy winnow
smeared over with some glutinous substance like birdlime (e.g., jak milk) is tied to a long pole and passed
over the heads of paddy, so that the insects are caught in large numbers on the sticky substance on the
winnow. The process has to be repeated over and over again. It is tedious, but simple and effective.
(5) An elongated cloth bag is run across the field sweeping in the bugs as they rise. The bag is either
soaked in crude oil emulsion (1 pint emulsion to 2 gallons water) or the inside smeared. with something
9(4)09
(2)
sticky. A bag, 8 ft. wide and 3 ft. high, is a convenient size, the sides kept open by bamboos 3 ft. long,
which serve as handles for grasping it. The width is about as much as two men can run with. A smaller
bag may be suspended by ropes (see fig.). Mr. Lefroy strongly recommends such an appliance, and
doubts whether any better will be found. The work is best done by co-operation and the treatment of
large areas together, as bags cost something to make. (6) It has been found that a mixture of bran and
jaggery serves as a bait for the bugs, and that they could be captured and destroyed easily when they
can be got to congregate together by this means.
An important point to be remembered is that the best work can be done by attacking the rice-bug
when in the field and before the rice comes into ear, and not by waiting till it has invaded the fields.
The cultivator should therefore look out for the insect and its eggs and destroy them. For, if let alone,
each pair will in a month or so produce about 24 bugs and in two months 288, and so on. The enemies
of the bug should also be recognized, and must never be destroyed.
[To make kerosine emulsion: Boil 4 lb. sliced bar soap in 1 gallon water till dissolved. Take off
fire and add 2 gallons kerosine, agitating mixture till a milky emulsion is formed. Dilute to required
strength (usually with 6 to 10 parts water) for use. Where crude oil is used, dilute each gallon with
66 gallons water, or 4 a pint to one kerosine tin water. |

NITROGEN-GATHERING CROPS.
Ir is needless to discuss the value of Papilionaceous crops in agriculture. The manner in which
these plants import atmospheric jnitrogen into the soil with the aid of the bacteria in the nodules on
their roots is now pretty well known, since it has been explained over and over again in the Society’s
publications and by its travelling instructors.
The question is: often asked, what ‘leguminous ‘crop ‘should: be grown with the objectZof its being
wholly. or’ partially returned to the land. The tendency in most matters is to look for something new,
and the newer the better! As a’general rule, however, these new plants are unsuitable to local conditions,
unless, of course, they came from countries with almost identical natural conditions.
Wild species of Crotalaria have been highly recommended and utilized with marked benefit both
in up-country and low-country estates. The difficulty, however, in inducing the native cultivator to
grow such a crop as Crotalaria striata is that he does not see sufficient virtue in a plant that does not
give him some tangible return.
For this reason, it is politic to reeommend to him—for the present at least—a crop which yields him
some useful produce. The American cow-pea (Vigna catiang) is a plant that has come back to}Ceylon
with a new name, since it is no more than a variety of the familiar mé beans largely cultivated,
particularly about Colombo. The legumes are wholesome and palatable when taken early, and command
a ready sale as “ curry beans.”
There are other crops which similarly yield marketable produce, such as dhall (Cajanus indicus),
san-hemp (Crotalaria juncea), dhaincha (Sesbania aculeata). Whether cow-pea or one of these three
should be selected is for the cultivator himself to decide after carefully considering the “ pros and cons ”’
of the case.
All are excellent in rotation, or as “‘inter-crops”’ in permanent plantations. The dwarfish forms of
cow-pea or mé are perhaps more suitable from the point of convenience, especially when grown as
inter-crops.
Dhall (Sin. rata-tora, Tamil thavarai), which yields one of the staple foods in India, is a shrubby
plant, which sometimes grows up to a height of 15 or,20 ft., and will suit cases where shade is also
a desideratum. These two plants (cow-pea and dhall) are therefore of economical value as food crops.
{In this connection may also be mentioned ground-nuts (Arachis hypogea), but the great difficulty
of protecting and harvesting the crop in Ceylon has made it unpopular among cultivators. ]
Crotalaria juncea and Sesbania aculeata, on the other hand, are fibre plants, and will suit localities
where there is use for fibre. The first is already under cultivation in, the Chilaw District, and in parts of
the Northern, Province, the fibre, which is extracted by the,simple process of retting or steeping in water,
being in requisition for fishing nets, &c. Dhaincha is practically unknown in the Island, but is closely
9(5)09
e
( 2 )
related to our katurumurunga (S. grandiflora) so commonly grown in vegetable gardens, and of which
both the flowers and leaves are used as food. The reasons why it is brought forward in this connection
may be stated as follows :—
(a) It is referred to in the “‘ Handbook of Indian Agriculture” as ‘‘ richer in nodules than
perhaps any other plant.”
(6)
(c) It is suitable for low wet land, and will therefore do for most paddy fields.
(d) It was recommended to Indian tea planters by Dr. Mann, and gave excellent results.
(e) ” and by
Roxburgh to be “ more durable than san-hemp for use in water.”
Dhaincha is a plant which, under favourable conditions, may grow up to about 14 ft., though it is
generally of smaller growth. When broadcasted fairly thick—say, at the rate of 30 lb. of seed per acre—
it keeps down weeds, and should be ready for cutting for fibre in 4 or 44 months, so that if sown in April,
the ground, fertilized by the crop-residue, will be available for other cultivation in September. The fibre
was at one time valued at from £30 to £35 per ton, but this valuation will have to be revised on a present-
day basis. The seed has proved useful as a famine food in India. Without any desire to exaggerate the
properties of dhaincha, the statement may be given for what it is worth that the lack of organic matter
and cohesion of soil particles in land is easily remedied by growing one or two crops of dhaincha.
The plant may be seen growing at the Government Stock Garden. Orders for the seed can be
booked through the Secretary.
