which, in the Volta River district, are situated at the foot of the
hilly country, in positions convenient for transport to the ports
of shipment. In addition to these, however, a good deal of buying
is proceeded with at smaller places in the midst of the growing
districts, but these probably represent the localities for the
transactions carried on by agents or middlemen. Until the produce
is actually in the hands of the shippers, the conveyance of cocoa is
almost entirely done by head-loads of about 60 lbs. The head-load is
the standard for trading, and the local price quoted is always with
reference to it. It is customary for the buying shippers to send
out their agents to the cocoa districts to arrange for the purchase
of the crops, and it is always necessary that such purchases should
be paid for in silver, no notes or cheques being accepted. Owing to
competition during the past few years, the agents have often paid
the grower a sum of money long before his crop was ready for picking,
in order to guarantee that it may be bought by no one else. This has
had the effect of making the grower careless in the preparation of
his crop, and has caused the production of much bad material. The
report that at another town, often distant by many days’ journey,
a higher price is being paid than that obtained in a market close at
hand, will frequently induce a native to convey his head-loads to the
distant market, regardless of the fact that the extra shilling or so
he may receive does not appear to be sufficient compensation for the
additional labour and time expended. This points to the fact that
the native does not put the same value on his time and labour when
he is working for himself as he does when he is employed by others.
The buyers of cocoa pack it in bags for shipment, and these are
conveyed to the ports by motor lorries or placed inside large casks,
similar to those used for palm oil, and rolled along the roads. Some
of the shipments are conveyed in river steamers on the Volta, and,
more recently, owing to the growers having found a better market
for a short time at Kumassi, a considerable amount was sent by rail
from that place to Sekondi. In consequence of the imperfect state
of dryness in which the cocoa is often sold by the planter, a great
amount of care should be exercised before mixing and packing. Sorting
is not much practised, and some of the beans often become attacked
by mildew before reaching Europe, which depreciates the value
of the whole package. It is partly owing to the disregard of the
precautions of sorting and final drying that the West African cocoa
has earned such a bad name, and if more shippers were to follow the
example set by the one firm that has erected a drying apparatus,
it would do much to improve matters in this direction. Cocoa is
difficult to dry completely in the growing districts by means of
the sun, as the atmosphere in these localities is often so humid
that the beans absorb moisture when removed from the sun’s rays,
and it is for this reason especially that the final drying should
be done by the shippers. Transport to the ports of shipment from
the growing districts will be facilitated by the construction of a
short railway, which it is contemplated making from Accra, and until
this is ready the carriage by head-loads, cask-rolling, and motor
lorries will probably continue. The presence of the “tsetse”
fly throughout the growing districts prevents the possibility of
draught cattle being used.
A system of pooling purchases was agreed upon some years ago by a
number of leading shippers, in accordance with which competition
among themselves was suppressed, and a fixed price was to be given
for all cocoa. This action was doubtless taken in order to prevent
ruinous competition, but had the effect of checking improvement in
the quality, as no encouragement was given to the planter to prepare
the cocoa with greater care. The few shippers who did not join in
this “combine” were enabled to obtain the better qualities at a
very slightly enhanced price. In 1906 the general quality of Gold
Coast cocoa had so deteriorated that the merchants were asked by
the Government for their assistance to improve it. This led to an
inquiry which revealed the state of affairs mentioned above. The
obvious remedy of paying a price according to quality did not find
favour with the combine, who appear to have argued that it would
not profit them to pay a higher price for the small variable lots
of improved produce which might result. It was stated by some of
the local merchants in Accra that Gold Coast cocoa was generally
suitable for sale in certain European markets, where it was adapted
for the manufacture of a cheap form of sweetmeat, and that, if the
quality were improved and the price raised in consequence, damage
would be done to a new and rapidly growing trade. The merchants
ultimately agreed to endeavour to improve the standard of quality,
and it was arranged that all the cocoa brought in to the markets
at Aimensa and Dodowa should be graded, with a view to regulating
the price according to grade. This plan fell through at the last
moment, as a test sample of picked cocoa was said to have been
priced at only 1_s_. 6_d_. per cwt. over ordinary “Accra” in
the European market. The fall in the value of the residue was said
to be uncompensated for by the small increase mentioned.
=Improvement of Quality.=—Inquiries conducted by the Imperial
Institute pointed to the fact that well-prepared Gold Coast cocoa
could obtain high prices in Europe. In 1907 a consignment was sent
to the Imperial Institute for examination and report, and proved to
be of good quality, and when subsequently sold, it obtained a high
price. This established confidence with regard to the possibility
of fine grades being prepared in the country. During this year,
owing to the action of the Fernando Po and San Thomé growers,
in withholding their crop, a greater demand was created for Gold
Coast cocoa, and the advent of large buyers, working outside the
“combine,” forced the local price to a high figure. This did
not assist in the improvement of the quality, as the competition
induced native buying agents to buy the produce in almost any form,
in consequence of which large quantities of imperfectly dried stuff
were obtained. On the market becoming steadier, many of the more
intelligent natives realised the advantage of careful preparation,
to which they are now turning their attention.
Towards this latter result Messrs. Cadbury Bros., Ltd., rendered
great assistance. This firm sent representatives into the country,
who proved to the natives that they were willing to pay an
enhanced price for cocoa prepared in a manner suitable for their
requirements. A fair amount of cocoa was purchased by them, and
demonstrations were made in some places with regard to the proper
mode of fermentation. In addition to this a number of seedlings
of the _Criollo_ variety were given to the Agricultural Department
for experimental work at the Aburi Botanic Station.
The _Forastero-amelonado_ variety, a hardy but commercially inferior
kind, has been mainly employed in plantations, and experiments
have been carried on for some years at Aburi with _Pentagona_,
_Caracas_ and _Cundeamor_ besides _Criollo_ mentioned above. Such
good results were obtained with _Cundeamor_ that, in 1913, keen
competition was aroused among planters to obtain seed. The years
1913 and 1914 are said to have shown an improvement in the quality
of the cocoa produced. The attention of the Agricultural Department
has been given to the general instruction of the natives in improved
methods of cultivation and preparation, both by means of lectures
and demonstrations at the Botanic Stations and by the issue of
pamphlets in English and the Twi language. There was at first an
insufficient staff for instruction to be given except at the Botanic
Stations, and only those growers who lived in the vicinity were able
to obtain benefit from it. After holding several conferences with
chiefs and planters in the cocoa districts it became evident that
the appointment of European Travelling Instructors was necessary, and
following this the Government detailed certain officers for the work;
the object being that they should occupy a large portion of their
time in travelling through the country in order to give personal
instruction to the natives in correct methods of treating cocoa
and other agricultural products. Persons selected by chiefs are now
trained to act as instructors in planting in their own native towns.
The preparation of a large quantity of cocoa of even quality is so
greatly dependent upon the similarity of the treatment and conditions
at a time when the material is undergoing fermentation and drying,
that it is almost imperative that a large quantity should be
prepared at one operation. This is an important consideration
in British West Africa, where native plantations range in size
from a few trees to about five acres in extent, the average
being perhaps about a hundred trees, or, roughly, one-tenth of
an acre. The production of each plantation is at present prepared
independently, and the result of one picking of pods, if all mature,
is often quite inadequate to yield sufficient for fermentation
purposes, it being recognised that a few hundredweights of beans
in their pulp are necessary for the satisfactory accomplishment
of the operation. The same difficulty has presented itself in the
West Indies with regard to the crops picked by owners of small
plantations, and arrangements are usually made by some larger
concern in the neighbourhood to purchase the pods from them. The
establishment of central fermenting and drying houses, controlled
by the shippers themselves, would perhaps get over the difficulty
on the Gold Coast and result in a superior class of cocoa being
produced. The planters would doubtless consent to sell their pods,
instead of performing the laborious work of preparation themselves,
and would probably be able to extend the size of their individual
plantations, which, by reason of their inability to prepare more
cocoa, single-handed, they have been unable, hitherto, to do. The
efforts of the Administration to improve the preparation have been
somewhat handicapped by the system employed by some merchants of
securing the crop for themselves, by money advances, with but little
regard to its preparation, and of pooling the produce.
Cocoa planting has revolutionised the native system of land
titles. Where only annual crops were under consideration, a
short, temporary occupation with subsequent reversion to tribal
ownership seemed an adequate provision, but with the establishment
of permanent cocoa plantations the planter claimed perpetual and
undivided proprietorship.
Further information regarding Gold Coast cocoa will be found in the
_Bulletin of the Imperial Institute_, 1907, p. 361; 1912, pp. 240,
556; 1913, p. 154; 1914, p. 387; 1915, pp. 149, 645; 1916, p. 123;
1917, p. 117; 1919, pp. 49, 102; and Johnson’s _Cocoa_, 1912.
=Exports of Cocoa.=—The exports of cocoa from 1900 to 1919 are
as follows:
Year Tons Year Tons Year Tons
1900 536 1907 9,355 1914 52,888

1906 8,975 1913 50,554
=RUBBER.= =Indigenous Species.=—The most important source of rubber
in the Gold Coast and Ashanti is the indigenous tree locally called
“Ofruntum”; a comparatively small amount is also derived from
some of the vines belonging to the same Natural Order, and from
one or more of the wild trees of the Ficus Order.
Reports on the quality and commercial value of some of the principal
kinds of rubber obtained in the Gold Coast are published in the
_Bulletin of the Imperial Institute_, vol. v. (1907), p. 248.
=Botanical Position of the “Ofruntum” Tree.=—The
“Ofruntum,” or African rubber, is botanically placed in the
Natural Order _APOCYNACEÆ_, under the specific name of _Funtumia
elastica_, Stapf. Until recently it was referred to as _Kicksia
africana_, Benth. and others (a genus which is not known to occur
in West Africa), and it was also confused with a very nearly allied
species, occurring in the same localities, and now known as _Funtumia
africana_, Stapf. Owing to the great similarity which these species
of Funtumia bear to one another, it is important that the differences
between them should be recognised, _F. africana_ not furnishing any
but very inferior rubber. The most reliable method of testing the
species which produces rubber, is by rubbing a small quantity of
latex between the finger and thumb, when small particles of rubber
should be quickly formed, the latex of _F. africana_ becoming
only a sticky mass under the operation. The leaf of _F. elastica_
can usually be recognised by the presence of a small pit at the
origin of each secondary nerve or vein on the under-surface,
which feature is not characteristic of the leaf of _F. africana_,
although recently individual trees have been found exhibiting this
peculiarity. The flower bud of _F. elastica_ is typically much
shorter than that of _F. africana_, and the double seed pod of the
former species is shorter and more blunt than that of the latter.
=Distribution of _F. elastica_.=—The Funtumia rubber tree occurs in
a wild state in the forests throughout the Gold Coast and Ashanti,
although it has been nearly exterminated in some parts. It appears
to be most plentiful in the dense forest regions of Northern Ashanti.
=Native Methods for Preparing.=—Funtumia rubber is exported
under the names of “Ashanti lump” and “Niggers,” which
consist of much adulterated, evil-smelling substances, for which
a low price is procurable in comparison with that paid for pure
rubber. In certain years the demand for this has been maintained,
but the adequate supplies of good rubber from elsewhere, and the
rapid expansion of the cocoa industry, have caused a diminution
in the export of native-made rubber, which has been replaced to a
small extent by plantation rubber.
The wild trees grow from 50 to 100 feet in height, and often
have a girth of three feet at four feet from the base; the trunk
being commonly without branches for a considerable height. The
native ascends the trunk by means of a sling passed round it,
to one end of which is a loop which fits over his right thigh
and to the other a stirrup in which he keeps his left foot. By
moving the rope up the tree the ascent is quickly accomplished,
and when stationary, both hands are left free. The climber carries
a gouge, or semi-cylindrically-faced chisel, with which he cuts
vertical as well as transverse oblique grooves, forming a rough
“herring-bone” pattern, which may be continued for the whole
length of the trunk, and even extend on to the main branches. To
make the cuts the tool is either used in one hand or is held in
the left and driven by blows on the end of the handle, given with
the palm of the right hand. The flow of latex commences at once,
and is directed down the vertical channel into a calabash placed
at the base of the tree, into which the latex is guided by a lip of
clay or a chip of wood. The illustration shows a native in Ashanti
tapping a tree (Fig. 18). The quantity of latex procured at the
one tapping varies; an exceptionally large amount being about two
quarts from a large tree. The tree is not tapped again for several
months and until the wounds have healed. On the second tapping
the same form of cuts is made upon the opposite side of the tree,
and the transverse channels often intersect those made previously;
besides this, owing to the want of regulation in the depth of the
cuts, the inner or cambium layer of the bark may be so damaged that
the intersecting cuts may ring the tree and cause death. Few trees
probably survive the third or fourth tapping.
[Illustration: “ODUM” TREES _CHLOROPHORA EXCELSA_.

[Illustration: PARA RUBBER TREE (_HEVEA BRASILIENSIS_), TAPPED
AT ABURI.
Fig. 20, p. 66.]
[Illustration: RUBBER TREE TAPPED, HERRING-BONE SYSTEM IMPERFECT,
ABURI.
Fig. 21, p. 61.]
If the herring-bone cuts were made carefully upon the lower part of
the trunk, and attention given to their depth and direction, the tree
might be preserved for a longer period. An illustration given shows
the incorrect mode of tapping, where the transverse cuts are opposite
instead of alternate (Fig. 21). Experiments seem to show that there
is not the same “wound response” in the case of Funtumia trees
as is found in that of the “Para” tree (_Hevea brasiliensis_);
the paring of the wounds some days after tapping yielding no flow
of latex similar to that procured in the first instance. On cutting
the bark area between the transverse channels, the latex cells
appeared to be empty and to indicate that a large area is drained
on the first tapping. Further investigation is necessary in order
to compare the results obtained from this tree with those of _Hevea_.
The latex of Funtumia will remain in an uncoagulated state for
a longer time than that of Hevea, but it may become damaged
by fermentation if a quantity is kept in bulk for a lengthened
period. The native does not usually produce a pure Funtumia rubber,
but mixes with the latex the latices of several other plants, among
which may be named “Odum” (_Chlorophora excelsa_), “Osese”
(_Funtumia africana_), “Ofo,” “Okre,” “Sindru”
(_Conopharyngia crassa_ and _Alstonia sp._). Having mixed some of
these latices with that of the Funtumia, the whole is heated and
poured into a hole in the ground, which has been prepared to serve
as a mould. Coagulation and decomposition proceed together at a slow
rate, and finally produce a rubber containing a number of holes which
serve as receptacles for the liquefied decomposed constituents. The
rubber mass is black outwardly, but whitish within, and is more or
less sticky. It is said that the latex of _Landolphia owariensis_,
the vine from which “Krepi ball” rubber is made, is sometimes
mixed with the rest to hasten coagulation.
=Improved Methods.=—In 1906 attention was drawn to the use of a
plant called “Niama” in the Ivory Coast, by which Funtumia rubber
latex was coagulated by adding a hot decoction of the leaves. This
plant was subsequently found to be _Bauhinia reticulata_, which bears
the name of “Otakataka” in the Gold Coast. Experiments with this
afforded excellent results. An examination of the plant made at the
Imperial Institute proved that the tannin contained in the leaves was
responsible for the coagulation of the latex, and that the infusion
of any plant containing tannin is equally effective. The obstacle
to the general use of _B. reticulata_ for coagulation, is that the
plant does not occur in the same localities as the wild Funtumia
tree. Doubtless other tannin-yielding plants may be found in the
rubber forests which would answer the purpose equally well, among
them the pods of _Acacia arabica_. A simple method of coagulation,
which was demonstrated to the chiefs and rubber collectors in 1908,
is that of diluting the latex with about four or more times the
volume of water, straining and boiling it, when the rubber quickly
separates and can be collected from the surface of the water by
means of a stick and immediately pressed into a rough biscuit.
The rubber made in the manner mentioned above has been valued
at more than twice the price obtained for the adulterated stuff,
but it appears difficult to persuade the local merchants to offer
a higher price for it, and it therefore suits the rubber collector
better to make the inferior quality. So long as this state of things
continues, it is to be feared that instruction in the improvement
of quality will not lead to the adoption of better methods.
In 1908 a Commission of Enquiry was appointed and made certain
recommendations for legislation for the protection of the
industry. Articles on Gold Coast rubber will be found in the
_Bulletin of the Imperial Institute_, vols. viii. (1910), x. (1912),
xi. (1913), xii. (1914), xii. (1915) and xv. (1917).
=Plantations.=—Large numbers of Funtumia seedlings have been grown
at and distributed from the Government Botanic Gardens at Aburi,
Tarkwa, and Kumassi, and some of the Ashanti kings and chiefs, who
have expressed a wish to attempt to renovate their rubber forests,
have obtained assistance from the officers of the Agricultural
Department, who have conducted planting operations in the forests
in the presence of those interested. Plantations under European
management and with European capital are in progress in the vicinity
of Axim and Sekondi. Most of the recently made plantations are said
to consist more of Para than of Funtumia rubber trees, although in
1913 one of these in the Dunkwa district of Ashanti was reported to
contain 20,000 trees of the latter kind. The tree appears to thrive
well when planted closely, and straight trunks are soon formed.
=Insect Pest.=—At Aburi and elsewhere the Funtumia tree is found
to be attacked by the larva of a moth of the family _Pyralidæ_,
identified as _Glyphodes ocellata_, Hampson, which denudes it of
leaves. No severe damage seems to be done by this pest, which has
only been observed in plantations, and was destroyed at Aburi by
repeated applications of lime and ashes.
=Fungoid Pest.=—A sooty fungoid growth is sometimes seen upon the
leaves, similar to that occurring on orange trees in the country,
and probably belongs to the genus _Meliola_. It is destroyed by
the application of sprays of Bordeaux mixture.
=Rubber Machinery.=—A fully equipped installation of rubber-washing
and crêpeing machinery was exhibited at the Kumassi Agricultural
Exhibition of 1908, and was subsequently taken over by one of the
leading mercantile firms at that place, where the local rubber
is now washed, crêped, and pressed before export. It might prove
advantageous to come to an arrangement with the rubber collectors
to bring the latex to Kumassi, where, under proper supervision,
it could be made into rubber of high quality. As the latex will
remain for a considerable time without alteration, it should not be
difficult to bring it in from places several days’ journey distant.
=Vine Rubber.=—Several species of vines, belonging to the Natural
Order _APOCYNACEÆ_, produce rubber in Africa, but the only one of
commercial importance occurring in the Gold Coast is _Landolphia
owariensis_, Pal. Beauv., from which “Krepi” or “White ball”
is obtained. Unless the plant is observed during the flowering
as well as the fruiting season, it is difficult to distinguish it
from some nearly allied, but useless, species of the same genus,
which are found commonly in the same localities.
The vine is found throughout the forest region of the Gold Coast
and Ashanti, climbing over and interlacing the main branches of
large forest trees; but an apparently terrestrial form of the same
species has recently been discovered in the ultra-forest region,
where the stunted habit in which it grows is probably occasioned
by the annual grass fires.
Under different atmospheric conditions the latex of _L. owariensis_
behaves differently. In the drier regions it coagulates upon the
wound almost immediately upon exposure to the air, whereas in other
and moister places it runs from the cut in such a manner as to allow
it to be collected in a vessel. The acid juices of some of the local
wild fruits are added to hasten coagulation, when this is necessary,
or the collector is said to smear the fresh latex upon his naked
body, until enough has been coagulated to form a small ball, which
serves as a nucleus for winding on the strings of fresh latex as
the new cuts are made. There is a quantity of “scrap rubber”
formed on the wedge-shaped cuts which it is usual to make, and this
is added to the ball, which attains a diameter of three or four
inches when complete. The crushing of the root and stem for the
manufacture of so-called “root-rubber” does not appear to be
practised in this country, although common elsewhere in West Africa.
On account of the colour and form of this rubber, the name of
“White ball” is usually applied to it, although, from the fact
that the Krepi tribes, living on the east bank of the Volta river,
produce a large quantity of it, the name of “Krepi ball” is
frequently given.
White ball rubber is seldom adulterated by the addition of other
latices, as these would retard coagulation and interfere with the
preparation of it in the manner mentioned. For this reason the
rubber sold under this name usually obtains a higher price than
other rubber.
_Landolphia owariensis_ presents many disadvantages for cultivation
in plantations, and the yield is small in proportion to the space
which the plant occupies. Several species of this and allied genera
are being grown experimentally at the Aburi Botanic Gardens.
“Flake rubber” is a name given to a very inferior quality of
rubber which is produced upon a small scale in many parts of West
Africa, but it has not been determined from which species of vine
that exported from the Gold Coast is obtained. In Northern Nigeria
_Carpodinus hirsutus_, Hua, is said to be the source of the exported
rubber of this name.
=Fig Rubber.=—One or more species of wild fig trees (_Ficus
sp._) are tapped for the production of what is locally termed
“Memeluku” rubber, and it is generally supposed that _F. Vogelii_
is that mostly employed. The trees attain a large size, and the
rubber is composed of the scrap, collected from a large number of
small cuts made on the trunk and branches. This scrap rubber is
pressed together into thick biscuits. The rubber has usually little
resiliency and breaks easily; it is, in consequence, of small value.
=Introduced Species.=—Experiments have been carried on for several
years with “Para” rubber (_Hevea brasiliensis_), “Ceara”
(_Manihot Glaziovii_), and _Castilloa elastica_, all indigenous
to South America. The last-named has been so badly attacked in
the Botanic Stations by boring beetle larvæ that it has shown
no promise of success. Ceara grows well, but for some reason
the production of latex from it is uncertain, and this has caused
little value to be attached to it in the Gold Coast, although in the
drier region of Togoland this species is being planted. Para rubber
seems to show much better results, although, up to the present, no
extensive experiments to ascertain the yield of rubber have been
made. Tapping two trees growing at Aburi, Mr. Johnson obtained a
larger quantity of latex than from _Funtumia elastica_ under the
same conditions; and following this an extensive area was planted
with Hevea trees at the Tarkwa Botanic Gardens, where the experiment
appears to be proving successful. Views are given of a tree at Aburi
(Fig. 20). Large plantations of Hevea are being made near Tarkwa,
Axim and Sekondi as well as in the Kwahu district, where the tree
seems to thrive remarkably well. A few of these plantations made
returns in 1913 showing promise of success. At one, on the Offin
river, there were said to be 90,000 Para trees of different ages,
20,000 Funtumia and 6,000 coffee (_C. robusta_). At another the
yield of rubber from a number of mature trees gave an average of
1·08 lb. of dry rubber per tree in eight months’ tapping, and a
third had 22,000 Para trees of which about 8,450 had been tapped and
yielded 10,565 lbs. of rubber, or 1¼ lb. per tree tapped. Labour
was reported plentiful and good. There are said to be many more
rubber plantations in the country from which returns had not been
received. Up to 1913 the Agricultural Department had distributed
250,000 Para seedlings and 1,500,000 seeds.
Commenting on the fluctuation in the exported amounts of rubber,
His Excellency the Governor (Sir Hugh Clifford), in his message
to the Legislative Council in October 1918, explained the
recrudescence during 1916 and 1917 as due to the development of
rubber plantations under European control. It remains to be seen
whether the Gold Coast will be able to successfully compete in
this work with the Far East. Articles on Para rubber from the Gold
Coast are to be found in the _Bulletin of the Imperial Institute_,
vol. x. (1912), vol. xi. (1913), vol. xii. (1914), vol. xv. (1917)
and vol. xvii. (1919).
=PALM OIL AND KERNELS.=—Records are available showing that the
export of palm oil from West Africa has continued for over one
hundred years, but the quantity shipped from the Gold Coast during
the last fifteen years shows a rapid decrease from the average of
the twenty years previous.
The tree which yields the oil of commerce is known as _Elæis
guineensis_, Jacq., and is placed in the Tribe _COCOINEÆ_ of the
Natural Order _PALMÆ_, together with the genus _Cocos_, to which
the Coconut palm belongs. (Cf. _Bull. Imp. Inst._, 1909, p. 357;
1920, p. 209.)
=Habits of the Oil Palm.=—The oil palm occurs most plentifully
in the moist regions near the coast, although it will not thrive
on land which is perpetually marshy. The palm becomes scarcer when
the dense forests of Ashanti are reached, but it is not entirely
absent until the ultra-forest tract commences.
The tree often bears fruit when it has only attained the height of
ten feet, which it is said to do about the seventh year, but the
yield is supposed to increase annually until the tree is thirty
or more years old, often continuing for a much longer time. It
is not possible to give any positive assurance on this point,
as observations have not been recorded for any length of time.
Although the oil is principally obtained from wild trees, one
extensive plantation in the Krobo Hills has been successfully
carried on for many years by the chief of Odumassi. His trees are
planted at regular intervals and care is given to their upkeep and
cleanliness. Concessions have recently been granted to Europeans for
planting as well as exploiting the wild palms, and experimental work
in the mechanical extraction of pericarp and kernel oil have given
some promise. Two British companies that have erected extraction
plants in the Western Province have laid tram-lines designed to
keep them constantly supplied with the palm fruit.
Trees that have become old and practically barren are usually tapped
for the extraction of “palm wine,” being frequently cut down for
the purpose. In some parts of the country fruitful trees are tapped
while standing, and, as this necessitates the base of the terminal
shoot being cut into, the tree is generally killed in consequence.
Two crops of fruiting heads are yielded by a tree in full bearing
each year, but the autumn crop is heavier than the earlier one,
and the aggregate weight of fruit yielded by a tree in one year is
generally estimated at 40 lbs.
The fruiting heads consist of large bunches which hang from near
the crown of the tree, and each fruit is partly enveloped in a
husk-like covering. When removed from this it is found to be smooth,
somewhat conical or irregularly compressed, tapering towards an
abrupt point. The colour when fresh varies from orange-red to
nearly white, with a more or less broad black apex. In section
it appears to be composed of a thick fibrous layer over a hard,
somewhat rounded stone, which contains a whitish kernel. It is
from the fibrous portion, which is included in what is botanically
termed the pericarp, that the oil is obtained, but the kernel also
contains another valuable oil, for the extraction of which it is
shipped to Europe to a large extent.
=Preparation of Palm Oil.=—When the ripe head has been cut from
the tree, it is left upon the ground for a few days in order that a
shrinkage in the fruits may occur, which renders them more easily
dislodged from their husk-lined places. The fruit also becomes
slightly dull in colour. The heads bearing the fruit are often
beaten to remove the latter, or they are individually broken out by
hand. In order to facilitate the extraction of the fruit kernels, the
fruits are usually buried in the ground in a pit lined with plantain
leaves. Here they remain for from three weeks to a month, during
which time decomposition is set up. The subsequent quality of the oil
is dependent upon the degree to which this is allowed to proceed,
rancid and thick oils resulting when it has been overdone. On the
other hand, the higher the state of decomposition the greater is
the facility for separating the fibrous pulp from the stones. On
removing the fruits from the ground they are placed in an open vat
(Fig. 15) and pounded by a number of people using long poles, after
which they are covered up for several hours in order that the oil
may drain into the small well shown at the side. Several consecutive
poundings are applied, until the fibrous pulp is quite separated and
most of the oil has drained out, after which the stones are combed
out with the fingers, and the pulp is placed in a bag and pressed on
a horizontal bar until the oil flows from it into a pit below. The
oils from these extractions are boiled and cleared, and the residual
pulp is often placed in the boiling pot so as to extract as much oil
as possible. This is the method employed at the Krobo Plantations,
but the operation varies slightly in different districts.
=Kernel Oil=—The value of the kernel for the extraction of oil
was recognised at a much later date than the pericarp, although,
in a few places in the Gold Coast, oil had probably been expressed
from kernels for local consumption for some time. Among the Krobos
the medicine-men prevented the trade in kernels from becoming
established for several years, but they were finally overruled by
the chiefs. A large and increasing trade in kernels continued for
a number of years, but this has fallen off to a small extent more
recently. The shell of the variety of kernel which appears to be
the most common in this country is usually thick, and the laborious
work of cracking each stone individually between two stones, in
such a manner that the kernel is extracted in an unbroken state,
prevents a larger quantity being prepared for sale, and results in
much waste. Nut-cracking machines have been brought into the country,
and are said to prove successful to some extent, but the native is
not in a position to use machinery, and most of the material shipped
is extracted in the primitive method mentioned. Cf. _Bulletin of
the Imperial Institute_, vols. vii., viii. and xv. (1909-17). Before
the cracking can be accomplished without breaking the interior, the
kernel requires to be exposed to the sun and thoroughly dried. Kernel
oil prepared in a native way is of two kinds, one which expressed
without heat being white, whilst that made from the roasted kernels
is dark brown. Both are made by pounding and grinding the kernel
into fine meal, the extraction of the one being effected by cold
and the other by boiling water.
In 1916 a Special Committee was appointed to consider the position
of the palm-kernel trade, chiefly with reference to the protection
of the newly-established British oil-crushing industry against
German competition; and it was considered advisable to recommend
the imposition of a differential export duty of £2 per ton on all
palm kernels from British West African ports. The Colonies concerned
imposed the duty at the rate mentioned and in some instances have
since supplemented it by a direct revenue-producing tax.
=Commercial Uses.=—The chief commercial uses of the oils are for
the manufacture of soap, candles, and glycerine, some qualities of
palm oil being made use of in the manufacture of tin plates. With
improved methods the supply of palm oil and kernels could be
largely increased.
=Varieties of Oil Palms.=—In 1907 information was obtained from the
Imperial Institute that a variety of oil palm was being propagated in
the Kameruns the fruit of which contained a thin-shelled kernel and
was called “Lisombe.” Further investigation in the British West
African countries led to the discovery that a number of well-marked
varieties of _Elæis guineensis_ were distinguished by the natives,
and were called by distinct names. Among these one possessed
a thin-shelled kernel, and, together with about eight others,
has been under investigation at the Imperial Institute, with the
object of ascertaining their respective merits. The thin-shelled
“Lisombe” and the “Gamopale” varieties from the Kameruns
have recently been tried experimentally in the Gold Coast, and
the advantages they possess over the other kinds have been clearly
established. From the descriptions given below of the more important
varieties found on the Gold Coast, it will be seen that particulars
of the comparative weight of the fruit crop and the quality of
the oil yielded are required to determine the relative values. In
addition the proportions of fruit- and kernel-oil of each as well
as the facilities for extracting the kernel must be considered.
A reference is given below to six varieties, which have been fully
examined at the Imperial Institute. The native names are given, and
the percentages have been calculated for comparison, from the more
elaborate figures which have been published (_Bulletin Imperial
Institute_, vol. vii. [1909], p. 366; cf. also vol. xi. [1913],
p. 208).
The characteristic variations of each variety are as follows:—
1. “Abe-pa.” Fruit large, orange-red, with or without black tip,
pericarp thin, nut large with thick shell. This is the commonest
form in the country, and is probably identical with the variety
found in Sierra Leone.
2. “Abe-dam.” Fruit of irregular shape, fairly large, bright
red, pericarp slightly thicker than the last, nut large with a
thick shell. This is not uncommon.
3. “Abe-tuntum.” Fruit moderately large, dark purplish-black,
pericarp very thin, and nut with thick shell. Uncommon.
4. “Abe-bobe.” Fruit usually rather small, red and black,
pericarp thick and soft, nut with a thin kernel (easily broken in
the teeth). Trees rather scarce. This is probably identical with
the “Lisombe” variety from the Kameruns.
5. “Intermediate form between 2 and 4.” Similar to the last
but with a thicker shell to the nut.
6. “Seedless kind.” A very rare kind, nearly corresponding with
the “Difumbe” variety from Angola, which, however, possesses
a kernel but no shell.
The following are the percentages based on the total weight of the
fruit, in each case taken as 100:—
Name Pulp Contg. Fibre Nut Contg. Shell
oil etc. Kernel
1. “Abe-pa” 30 20·13 9·87 70 19·6 50·4
2. “Abe-dam” 37·5 24·03 13·14 62·5 16·87 45·63
3. “Abe-tuntum” 32·5 14·33 18·17 67·5 17·55 49·95
4. “Abe-bobe” 63 36·02 26·98 37 19·98 17·02
5. “Interm. 2 and 4” 51 30·34 20·66 49 20·58 28·42
6. “Seedless” 100 76·00 24·00 rarely a trace
Nos. 4 and 5 seem to be most valuable from a commercial standpoint,
although at present Nos. 1 and 2 are the most commonly used, owing
to the comparative scarcity of the first two mentioned. No. 6
is chiefly interesting from a botanical aspect, and is probably
incapable of reproduction. The sacred palm known in the Gold Coast
as “Abe-ohene,” and identical with “Ope-Ifa” of Southern
Nigeria, belongs to a new species called _E. Thompsonii_, Chev.,
but the fruits are not employed for the extraction of oil.
=OTHER OIL SEEDS.=—Experiments were conducted at the Imperial
Institute in 1908 with the kernels of the “Crabnut” (_Carapa
procera_, D.C.). The kernels were found to contain nearly 50 per
cent. of oil, which was reported to be worth about £20 10_s_. per
ton, but the residual cake could not be used for feeding purposes,
owing to the presence in it of a bitter constituent, and, on account
of the rather low manurial value, was estimated as worth only £2 per
ton (_Bulletin of the Imperial Institute_, vol. vi., 1908, p. 362).
The oil seemed to be well suited for soap-making, but would not be
suitable for lubricating or for edible purposes. The nut does not
occur in such profusion as to warrant profitable exportation from
localities where the oil palm is found.
=TIMBER.= =Mahogany.=—The most valuable and commonly exported
timber is that known in the European and American markets as
“African Mahogany.” The value of that shipped from the Gold
Coast in 1913 was estimated at £366,000.
Several red woods are included under the name of Mahogany, but
the best quality is said to be obtained from _Khaya senegalensis_,
a large tree of the Natural Order _MELIACEÆ_. This tree is known
by the native (Fanti) name of “Dubini.” In the same language
the names “Okumankra” and “Akwabohori” are applied to two
trees which are said to be exported as Mahogany, but of these the
identity has not yet been determined.
=Other Timber-trees.=—The “Odum” tree (_Chlorophora excelsa_)
produces a hard and useful wood, which is much used in the forest
region, but is not often shipped (Fig. 19). In the dry country of
the Northern Territories _Pseudocedrela Kotschyi_ may be found of
value as a red wood for decorative purposes.
Among the other trees which show evidence of yielding hard and
useful woods are “Ahedua” (_Cyanothyrsus sp._), “Opapeh”
(_Afzelia africana_), and “Bako” (_Mimusops sp._). Information
about the working-quality and suitability for export of these and
other Gold Coast timbers is given in the _Bulletin of the Imperial
Institute_, vol. viii., 1910. p. 232.
The largest, and consequently the most valuable, trees belonging to
the different species mentioned, are found in the western part of the
Gold Coast and Ashanti, and most of the mahogany logs are shipped
from Sekondi, Axim, and other places farther to the westward. The
Pra and Ankobra rivers are utilised to float down the squared logs,
which are then moored at the river mouths, to await shipment. The
export of logs is only limited by the facilities with which they
can be brought to a river or the railway, and large, valuable
trees are plentiful in many of the forests, although they would be
unprofitable to fell and trim in some cases, owing to their remote
situations and the difficulties connected with conveyance.
=KOLA.=—Kola-nut is the name usually applied to the fruit of a tree
belonging to the Natural Order _STERCULIACEÆ_, and the wild as well
as the cultivated forms found in the Gold Coast and Ashanti are,
probably, all referable to the species _Kola acuminata_, R. The
fruits or nuts are borne in large pods, each of which contains a
variable number. The nuts themselves are irregular in form, and
have an inconstant number of cotyledons, or seed divisions, varying
from two to five. Some confusion seems to have been caused owing to
this variation, as well as on account of the colour and shape of the
nuts. In some trees they are red, in others white, and others again
pink, and they may be elongate or nearly round. These, however,
are not reliable as distinguishing characters, since nuts of the
three colours have been found on the same tree, and even in the same
pod. Analyses and commercial valuations of several varieties of kola
nuts from the Gold Coast are published in _Selected Reports from the
Imperial Institute_, Part III., “Foodstuffs” (Colonial Reports,
Misc., Cd. 5137, 1910), pp. 259-61; _vide_ also _Bull. Imp. Inst._,
vols. x. (1912) and xvii. (1919).
In the forests to the north of Kumassi large wild kola trees are
found, and the nuts are collected by the natives inhabiting the
villages in the vicinity, where they are sold at from 6_d_. to
9_d_. a hundred. In other places the trees are planted, commonly
on the outskirts of villages, especially in Akim and Kwahu.
Kola nuts are used in tropical Africa in the same manner as betel
nuts are in Asia. Their taste is somewhat bitter, and the mastication
of fresh nuts seems to increase the flow of saliva. Chewing kola
nuts is resorted to by the natives in order to allay thirst, or
even hunger, and for this reason they are in great demand among
the inhabitants of the Sudan, to which country they are largely
exported, being carried by men and donkeys in caravans, which
travel from the forest limits of Ashanti through the Northern
Territories. The donkeys, which are chiefly used to transport the
nuts, do not generally enter the forests, but the kola nuts are
packed in elongated head-loads, in bamboo or palm-stalk frames,
in which form they are carried to the place where the donkeys have
been left. The caravans bring shea-butter, guinea corn, cattle,
and skins, which they exchange for kola.
The weight of nuts exported from the Gold Coast is about 50 per
cent. above that of Sierra Leone, but, in value, the latter are worth
from three to five times as much per ton. The fresh nuts are shipped
to Lagos and are transported far into the interior by Haussa traders.
=COTTON.=—No record is available to show when the tribes of the
forest country commenced to cultivate and use cotton for local
requirements. It has been stated that the people of the kingdoms
of the Western Sudan were acquainted with the uses of the fibre,
and have cultivated the plant, from a remote period, and it is
probable that contact with these people, during their expeditions
against the tribes to their south, led to the adoption by the
latter of cotton-growing upon the small scale in which it still
remains at present. Cruickshank, writing of the Fantis in 1853,
says: “They spin the thread from the cotton which grows in
the country, but they more commonly make use of the thread out
of English cloths, which they pick to pieces.” In speaking of
the Appolonians, a tribe inhabiting the coast region near Axim,
Cruickshank remarks that they “make fine grass cloths, which are
strong and durable.” In Ashanti, until recently, a cloth was
commonly made from the inner bark of a tree, generally supposed
to be _Antiaris toxicaria_ var. _africana_, which was produced by
the removal of the woody portions by beating, leaving a pliable
material composed of the interlacing fibres. These instances are
cited to show that the value of cotton for cultivation has not been
recognised by some of the large and dominant tribes in comparatively
recent times. Since cotton clothing has begun to be appreciated,
the necessity of growing the plant and weaving has been somewhat
checked by the large imports of finished material from Europe.
Throughout the forest region occasional plants of cotton may be
seen growing near villages, but the systematic cultivation of the
plant is only met with on the outer northern boundary of the dense
forest and in the Krepi country to the east of the Volta river. The
inhabitants of the northern forest boundary are a mixed people,
many of whom have probably been driven from the countries farther
north, where cotton is a recognised field crop, whence they have
introduced the cultivation. The adoption of cotton-growing by the
Krepi tribes may be due to similar reasons, although there appears
to be no evidence in support of this conjecture.
In the last-named places the seed is sown in rows on the tops of
ridges, on the sides of which maize plants may be also grown, but
it is not uncommon to find cotton plants growing alone. This is
especially the case on the northern limits of Ashanti. The large
varieties grown in these places are often left in the ground for
a second season and produce two crops, the last of which is said
to be inferior. No system of rotation has been observed, although
it is probable that the cotton is planted during the early years
of cultivation immediately following the yam crop, which is the
practice in some other West African countries.
Three distinct forms or varieties of cotton are cultivated in the
forest region. The first variety is usually referred to as “Green
seed,” and is the commonest one grown. The lint is long-stapled
and nearly white, but experiments seem to show that this form does
not yield heavily. The second form is recognised by the seed being
dark brown or black, without any fuzz, except a small brown tuft at
the apex, which has a sharp spike. The lint of this kind is creamy
white, and the plant is known as “Volta.” The third form differs
in having the dark brown seeds adjoining one another, and forming a
conical mass, from which it is difficult to separate the individual
seeds. At the point of connection each seed bears a small light brown
patch. This form is generally known to the officers at the British
Cotton Growing Association plantation as “Kidney.” All these
varieties are cultivated throughout the forest country, and extend
to some distance beyond; being replaced in the drier parts of the
Northern Territories by a small plant with a white woolly seed. No
cotton in a wild state has been seen in the country, and isolated
plants, found springing up in open places surrounded by forest,
are generally easily traceable to formerly existing cultivation.
The “Green seed,” “Volta,” and “Kidney” cottons,
which are grown in the Gold Coast, are different in habit from
the American and Indian plants, although in form they are similar
to Sea Island and Egyptian, having, perhaps, arisen from the same
original stock. The forms mentioned as cultivated locally attain
the height of from seven to ten feet in nine months from the time
of planting, and the stem near the base is often thicker than a
man’s wrist. The cotton bolls continue to open for three months
or more, and often as many as two hundred bolls are produced on a
single plant in one season. If left for a second year the bolls are
generally diminished in size. The soil which appears most favourable
for growth is a sandy loam containing much humus.
From January to April the bolls ripen continuously, and the cotton
is placed in the sun as soon as it is picked, in order that the
“Seed bugs” may be driven out. In native markets small quantities
are usually exposed for sale in an unginned form throughout the
harvesting season. No gin seems to be in use in the Gold Coast for
native work, and the lint is pulled off the seeds by hand when a
supply is required for spinning.
The greatest damage is done by “Seed bugs” of three
species—_Oxycarenus hyalinipennis_, _O. Dudgeoni_, and
_O. gossipinus_—that infest the lint as soon as the bolls open,
and undergo their complete and rapid metamorphoses during the period
between the opening and the throwing out of the cotton, feeding
meanwhile upon the juices which they suck from the seeds. The injury
caused by the puncturing of the seed often renders it unfertile. A
“cotton stainer” is also common on the plants, and damages the
unopened bolls by puncturing, and the lint by a yellowish stain
which it makes. This insect is known as _Dysdercus nigrofasciatus_,
and it is at least four times as large as any of the species of
_Oxycarenus_, on which it may possibly feed to some extent.
An attempt was evidently made, in the middle of the last century,
to establish the cultivation of cotton for export, and Cruickshank
mentions that an association had taken the matter up, and that
several of the native chiefs were beginning to give it their
attention about that time. Very little success seems to have attended
these efforts.
About 1903 the Government of the Gold Coast commenced the plantation
of an area in the Krepi country, at a place called Anum, and, under
the control of the Agricultural Department, this was transferred
to a better site soon afterwards, at a place named Labolabo on
the east bank of the Volta river. In addition to the extension of
about two hundred acres of land, which were planted with native and
American varieties of cotton, encouragement was given to the natives
in the vicinity to grow more, on the understanding that their crops
would be purchased from them at one penny per pound. Unfortunately
no arrangements had been made to store or gin a large quantity of
seed cotton, and the entire native crop could not be taken over when
brought in. This seems to have induced the native growers to convey
most of their cotton into Togoland, where they were able to dispose
of it at a fair price. Arrangements had to be made with a local
firm possessing a ginning machine, which was erected about sixty
miles lower down the Volta river, by which, on payment of a certain
rate, the seed cotton grown on the Labolabo plantation was ginned
and prepared for shipment. It was soon recognised that the expense
of transport of the seed cotton for this distance, and the price
charged for ginning, prevented the production of cotton for export
except at a heavy financial loss. The co-operation of the British
Cotton Growing Association was asked for, in order to supply gins
at Labolabo, and in 1906 three hand gins were sent from the Gold
Coast Exhibition, which had just been held. The machines were much
damaged in transit, and it was some time before the large stock
of seed cotton, which had accumulated, could be worked off. Soon
after this the Labolabo plantation was transferred entirely to the
British Cotton Growing Association, and an annual grant was made by
the Government to assist in the working. In 1907 a large steam-power
ginnery was put up, and the native farmers again began to bring in
their seed cotton for sale, but still a considerable quantity was
reported to be diverted to Togoland, where the price offered was
a fraction higher than that paid by the Association.
The cotton bales are transported from the ginnery by means of native
canoes as far as Amedika, which is the highest point on the Volta
to which small steamers can ascend, but great risk is entailed in
descending the rapids between Labolabo and this place. The cost
of carriage by native canoe is arranged at twenty shillings a ton,
and the bales are pressed into a suitable form for conveyance.
=American and other Exotic Cottons at Labolabo.=—A large number
of different kinds of American cottons have been tried at Labolabo,
but most of them have proved unsuccessful. Those which yielded a
good crop for the first year have generally been found to produce
seed, which, owing to the greater susceptibility of the plants to the
attacks of insects, refused to germinate in the following year. Some
of the lint produced was, apparently, of excellent quality and sold
well, but the necessity for the renewal of seed each year formed a
serious obstacle to the establishment of a new variety. The plants
from American seed are not so hardy as those from native seed, and
the necessity for greater care in cultivation renders them unsuitable
for use by the natives. Sea Island and various Egyptian cottons
have not proved successful. See _British Cotton Cultivation_, by
Professor Dunstan (“Colonial Reports,” Miscellaneous, Cd. 3997,
1908, pp. 28-30), and the _Bulletins of the Imperial Institute_,
vols. vii., x., xi., xiii., xiv. (1909-16).
=Attempts at Hybridisation.=—In the early days of the plantation
the Agricultural Department made several experiments with a
view to the establishment of a cross between the native and the
American plants, but the subsequent changes in the management of
the plantation resulted in the disappearance of most of these;
subsequently several others were attempted in 1906 and 1907 by
Mr. Fisher.
In all cases plants of the “Green seed” or the “Volta”
native forms were made use of as female parents, and the descendant
plants partook of the characters of the native forms in every way
for the first generation, but in later generations seem to have
produced a number of various types, from which it is now necessary
to make a careful selection. The quantity of lint yielded by the
first generation of plants, from the experiments made by Mr. Fisher
in 1906, is said to have reached a higher figure, per acre, than
that of any other form grown on the plantation, and the quality
was satisfactory; but that of the second generation appeared to be
unequal in type, and could scarcely be compared for quantity owing
to the unfavourable season. The American plants used for pollination
in the 1906 crosses were those which have given the best results
among the exotic forms planted, and are called “Black Rattler”
and “Richmond.” Of the four crosses attempted in that year,
that of “Black Rattler” × “Volta” was said to have proved
the most successful in point of yield.
Small plots of native and American cottons have been planted at
Kumassi, and experimental plants at Aburi, but the conditions have
not been so favourable at these places as at Labolabo. At Obuassi,
in Ashanti, an attempt was also made, but the soil seemed too stiff
and the plants were not healthy. Land suitable for native cotton
farms seems to be that on the west bank of the Volta river, north
of the Labolabo plantation.
=Valuations of Samples examined at the Imperial Institute.=—The

The cottons from native varieties crossed with American represent the
first generation only, as in no case were the following generations
found constant.
The large profits which have been made from cocoa in the forest
country have caused cotton-growing to be neglected, and it seems
improbable that large quantities of cotton will be exported from
this region during the next few years. In the same part of the
country palm oil and rubber are easily collected, and, besides being
more remunerative products, require comparatively small exertion
in preparation. An attempt to establish cotton cultivation upon
a commercial scale, among the industrious people of the Northern
Territories, was made by the British Cotton Growing Association,
but the immense distances of the inhabited tracts from a shipping
port and the consequent expense of transport, combined with the
uncertainty of the rainfall in these ultra-forest regions, compelled
the abandonment of the venture in 1916.
=FIBRES.=—Piassava fibre, which has sometimes been called
“vegetable whalebone,” is prepared from the sheath of the lower
parts of the leaf-stem of a tree belonging to the Natural Order
_PALMÆ_, and classified as _Raphia vinifera_, P. Beauv. This tree
is found growing in the vicinity of streams, and occurs commonly
in the forest regions near the coast.
The natives prepare the fibre, which is sold in the European markets
under the name of “Piassava,” by cutting the stem-sheaths and
steeping them in water for a considerable time until the fibrous
strands are easily separated by beating. After being extracted in
this manner they are dried in the sun. Only a small quantity is
exported from the country, but it is a more important article of
export from Sierra Leone and Liberia. As the specific name denotes,
wine is extracted from the tree, by tapping the standing or felled
tree, in the last case with the aid of fire.
On the estate of the African Plantations, Ltd., near Axim,
a fibre of excellent quality, commercially allied to jute, has
been prepared from the stems of a herbaceous plant, which was
supposed to be _Triumfetta semitriloba_, Linn., but which has since
been determined at Kew to be _T. cordifolia_ var. _Hollandii_,
Sprague. The plant belongs to the same Natural Order as Indian
jute—namely, _TILIACEÆ_. A description of this fibre is given
in the _Bulletin of the Imperial Institute_, vol. vi. (1908), p. 241.
This species has been observed commonly in a wild state in the
forests near Sekondi and Axim, but does not seem to be present in
the interior of Ashanti or in the country towards the Volta river.
Experiments made at the estate of the African Plantations, Ltd.,
are said to show that the best fibre is obtained from stalks which
have been retted or steeped in water for five days, but it will
probably be found that the period required for the operation is
dependent to a great extent upon the age of the stalks used.
The fibre may be prepared by stripping the bark layers from the
soaked stalks and beating these upon the surface of the water until
the actual bark is removed, when the fibre may be dried in the
sun; being finally picked over to get rid of the small remaining
bark particles.
The plant exhibits some advantages for cultivation over jute,
in that it may be cropped twice in one year and treated as a
perennial. Collection of the wild growths would be unsatisfactory
for the production of the fibre upon a large scale, owing to the
time occupied in searching for the plants, but it seems probable
that the plant would repay planting, especially if some better
method of extraction were devised.
The composition, quality, and commercial value of a large number
of fibres obtained from plants indigenous to, or cultivated in,
the Gold Coast are discussed in _Selected Reports from the Imperial
Institute_, Part I., “Fibres” (Colonial Reports, Miscellaneous,
Cd. 4588, 1909), pp. 43, 51, 84, 89, 90, 115.
=SILK.=—A species of wild silkworm is commonly distributed
throughout the forests to the north of Kumassi, and has been
identified as _Anaphe venata_. The silk cocoons of this species
and those of _Anaphe infracta_ are used in Nigeria for spinning
into yarn for weaving the “Saṉyaṉ” cloths of that country,
but no use is apparently made of them in Ashanti. The worms live in
small colonies, and form their cocoons in a common envelope of silk,
from which two or three somewhat tubular processes project to enable
the moths to emerge when the time arrives. The food plant of the
silkworm has not been definitely ascertained, but, as the cocoons
are found on a large number of herbaceous plants as well as trees,
it seems probable that several plants are eaten by it. The quality
of the silk is said to be good, and the colour is usually a golden
or light brown.[3]
=COPAL.=—The tree which produces this resin, often miscalled
“gum,” which is commercially known as “Accra copal,”
occurs throughout the forests of Ashanti and Akim, and has not
yet been specifically determined. Investigations have shown that
it is allied to _Cyanothyrsus oblongus_, Oliver, which yields the
“Ogea” resin of Lagos, and which belongs to the Natural Order
_LEGUMINOSÆ_. The flowers obtained from the Ashanti trees are of
a similar construction to those of _Cyanothyrsus_.
Locally the resin is commonly used for torches and for the
preparation of a scented pigment called “Krobo,” which is used
for elaborating patterns upon the skin, being commonly employed
by the Akim people for this purpose. For export the chief value is
for the preparation of varnish.
The quantity exported reached 178 tons in 1907, after which it
declined, and now no longer reaches a significant figure. The
overwhelming interest attracted by cocoa has led to its
disappearance. Cf. _Selected Reports Imperial Institute_, pt. ii.,
“Gums and Resins” (Col. Rep. Misc., Cd. 4971, 1909), pp. 172-5;
_Bull. Imp. Inst._, vol. xii. (1914), p. 220.
The copal-yielding trees are generally of immense size, and the
resinous liquid may be observed exuding from the main trunk as well
as the branches, in such a way as to form elongated “tears”
or slabs, which harden on exposure to the air. When these become
brittle they are broken off by wind and fall to the ground. Often
the flow of resinous liquid seems to be so profuse that quantities
reach the ground and form what is termed “fossil copal,” owing
to the fact that it is dug from the ground beneath the trees.
There is evidence to show that in some instances the original flow of
the resinous liquid is caused by deep borings in the sap wood made by
insect larvæ (probably _Coleoptera_—beetles), signs of which are
commonly apparent on old trees, which yield the most copal. Specimens
of branches, which have been tunnelled by these larvæ, have been
collected, exhibiting all the cavities filled with hardened resin.
Compared with the copal produced by _Copaifera Guibourtiana_, a
tree which is found in Sierra Leone, the Ashanti product is much
inferior, although the price paid renders it sufficiently valuable
for collection and export. Several different types of the Accra
copal are known, some of which appear to be of less value than
others, although apparently yielded by the same tree. That which is
deemed preferable is clear and pale yellow; milky pieces should be
sorted out, as they are valued at a lower figure. Blocks have been
obtained which weighed over twenty pounds. Sorting is said to have
been adopted by some of the local merchants, and as high a price as
60_s_. per cwt. is reported to have been obtained for sorted copal.
=COPRA.=—Some special attention has been given to the extension of
the copra industry on the coast, and it will be observed that the
average annual exports have nearly doubled during the last eight
years. The coconut (_Cocos nucifera_) is found on the greater part
of the coastline, and the dried contents of the nut constitute
the product known as copra. (Cf. _Oil Seeds and Feeding Cakes_,
Imp. Inst. Monograph, 1915.) No use is apparently made of the fibrous
covering of the nuts, which is exported from other parts of the world
under the name of coir. Locally the nuts are cut down in an unripe
condition, and the “milk” from the interior is used as a drink.
=DYES AND PIGMENTS.=—Camwood is the trade name applied to the
wood of a tree known as _Baphia nitida_, Afzelius, belonging to the
Natural Order _LEGUMINOSÆ_. It has been suggested that the bright
red colouring-matter is produced by decomposition on exposure to
air, the material shipped from different places in West Africa
being apparently in this condition, but investigations in other
parts of West Africa show that the fresh wood is frequently used in
making the colouring-matter. A very small quantity is exported from
the Gold Coast, but the natives make some use of it for staining
different materials.
=Indigo.=—This is prepared from two or three species of
_Indigofera_, which are found growing near villages, but the
process of preparation in the Gold Coast does not appear to have
been recorded, though probably similar to that employed in the
other West African countries.
The resin from the copal tree, mentioned above, is crushed, together
with the bark of a tree called “Krobo,” in Akim especially,
and the balls formed from this mixture are rubbed down, with the
addition of a little water, into a fine sort of lather, when a
greenish-grey-coloured thin paste is procured. With this designs
are traced upon the body and arms as an adornment for women, the
resin imparting to the mixture a pleasant odour.
=FIELD CROPS.=—The soil throughout a large part of the forest
country is very fertile, and no difficulty is experienced in
producing sufficient crops for local needs from a small area of
ground. The usual method is to cut down a piece of forest, leaving
those trees which are too large to be removed or burnt, or which
may yield one of the wild fruits which is appreciated. The stumps
and roots are not removed when only maize (_Zea mays_) is intended
to be grown, but are, to some extent, when yams (_Dioscorea sp._),
or groundnuts (_Arachis hypogea_), are to be cultivated. The
cut “bush” is permitted to dry in the sun for several weeks,
when it is burned, and the ashes are sometimes scattered over the
land. For plantations of maize, the soil is only turned up at the
spots where the seed is to be put in, and very little cultivation is
given for the remainder of the year, although weeding and earthing
up are resorted to in a few places. For the cultivation of yams or
groundnuts, the larger roots are dug out, and the whole field is dug
with small hoes, the soil being scraped together into small mounds,
on the top of which the yams or groundnuts are planted. In the
case of the former, stakes are also put in, upon which the yams are
trained to grow. In addition to this it is usual, in most places,
to plant maize upon the sides of the mounds, and okra (_Hibiscus
esculentus_) and peppers (_Capsicum sp._) in various parts of the
field. Guinea corn (_Sorghum vulgare_) is rarely seen within the
forest limits. Between the mounds, at wide intervals, plantains
(_Musa sapientum_) are generally grown, and occupy the ground after
all the other crops have been removed. In the country near the coast,
as well as in the Volta district, cassava (_Manihot utilissima_)
is a common terminal crop, although it is not frequently grown in
Ashanti. The length of time during which the land usually continues
to yield a grain or root crop, of the kinds above mentioned, seems
limited to about three years. Koko yams (_Colocasia antiquorum_)
are planted in damp places near the villages or beside streams,
and, in the Volta district, sweet potatoes (_Ipomœa batatas_)
are cultivated to a small extent. Small gourds (_Cucurbitaceæ_)
are cultivated in the villages, but are not common, and pineapples,
paw-paws, guavas, oranges, custard apples, sour-sops, and limes may
be found growing in the places near the older European settlements.
Plantains and yams seem to form the chief food of the people in
the interior, but maize is largely used by those near the coast,
who are better cultivators. Plantains are prepared by roasting or
by chopping up and boiling. In some parts, especially in the Krepi
country, the fruits are split and cut in pieces, after which they
are dried in the sun. They become hard and white in the process,
and can be kept for some time. Yams of several kinds are cut up
after peeling, and boiled with peppers or made up with palm oil,
when they form a favourite dish. They are sometimes pounded in a
wooden mortar and made into balls. Maize is ground on flat or grooved
stones by means of a stone hand-roller, after which the flour is
made into dough and baked, a little palm wine having been added
to make it rise. Cassava is treated in the same manner as yams,
but the former requires long soaking before cooking. Palm oil or
groundnut oil is generally used for cooking, and the pulp of the
palm fruit, after the oil has been removed, is eaten. A fermented
drink is made from maize, which is said to taste like weak beer,
but the chief intoxicant made locally is the fermented juice of
the oil and the fibre palms.
With the exception of cotton, which has been separately referred to,
groundnuts appear to have been the only field crop of importance
that has been exported. In 1908 a substantial figure was reached,
but has since declined.
PART II.—THE NORTHERN TERRITORIES
=Tribes.=—The country which is included under the Northern
Territories is inhabited by a number of tribes, now chiefly located
in the northern half; the central portion being liable to inundation
at certain times, and therefore almost unoccupied, and the southern
being, perhaps, considered unsafe owing to the proximity to the
warlike Ashantis. The more important tribes are the Mamprussis,
under the king of Gambaga; the Gonjas, under the king of Kombe;
the Walas, under the king of Wa; and two sections of the Dagombas,
under the chiefs of Savelugu and Karaga (formerly under the king
of Yendi, in German territory). The Lobis, Dagartis, Grunshis,
Kussassis, and several others were dispersed by Samory and Barbetu
in 1896 and 1898, and have now only nominal chiefs. (See _Colonial
Reports—Annual_, No. 566, “Northern Territories of the Gold
Coast,” 1907, p. 8.) The Moshis, whose country extended into
the northern limits of the Northern Territories, were employed
at one time as native levies, but since they were disbanded they
have interfered with the tribes on the Gambaga-Kumassi road, in the
Sapari Hills, and made trading by that route unsafe. (See _Colonial
Reports_, _loc. cit._, p. 10.) Steps have been taken to expel them
from the country, and it is hoped that the people living in the
hills, who are said to be good agriculturists, will now come into
closer contact with civilisation. The Dagombas are apparently the
most industrious tribe in the country, and they seem to be numerous.
Although there does not appear to be any actual record of the
invasion of the eastern part of the country by the Mohammedan
rulers of the Western Sudan, they are said to have overrun the
pagan countries between themselves and the region of dense forest
on several occasions. In 1483 the kingdom of Mossi (Moshi) was
conquered by Sonni Ali, King of Songhay, who was a native of the
Eastern Sudan, and had come from Egypt. Two years later he extended
his conquest through the mountain territory to the south and far into
the pagan belt. Sonni Ali was followed by Askia, who again overran
Mossi, in order to abolish paganism and establish the Mohammedan
faith. This occurred in about the year 1500, and doubtless the
people learnt to adopt the improved methods of agriculture which
the conquerors had introduced into the Western Sudan from Egypt
and the east. Many of the tribes have relapsed completely into
paganism, but amongst others there is a mixture of Mohammedanism and
paganism, which is evidence of the impression made. More recently,
Samodu Almami of Ouassoulou, generally known as Samory, was driven
from his kingdom in the Western Sudan by the French, and overran
the Northern Territories with his Sofa troops; subduing Wa, Bole,
and the whole of the western part of the country. It is, however,
unlikely that agriculture was further improved by his invasion,
as large tracts of country were devastated to feed his troops.
=FIELD CROPS.=—The soil is of a lighter and more sandy nature than
that generally found in the forest region, but it is well adapted
for the cultivation of many different kinds of crops, notably Guinea
corn, millet, groundnuts, and cotton, while it is less satisfactory
for yams. The latter are consequently of smaller size.
=Cotton.=—The cotton grown by the Dagombas is whiter than
those found in the south, and the plants are of small stature;
the species has a wide-opening pale flower, and has been grown
at Labolabo from seed procured in the Northern Territories. The
cotton fields are planted with regular lines of plants, and the
ground appears to be exclusively used for the crop during the
season. The seed is sown upon ridges which have been constructed
from the high conical mounds, upon which the combined crop of
millet (_Pennisetum spp._) or Guinea corn and yams were grown in the
previous year. Cultivation is performed by means of a short-handled
hoe, and the ridges are kept clear of weeds and grass until the
crop is ready. The seed-cotton is sold in the markets, and is in
good demand for the manufacture of native cloths. No insect pests
have been observed attacking the plants, and it is probable that if
an outside demand were established for the produce a large quantity
could be grown. It might be necessary to introduce a better variety
than that at present cultivated, as this yields a rather coarse and
short staple. If cotton from this part of the country is to become
an article of export, the difficulties at present experienced in
transport will first have to be overcome; indeed, this applies
to all the produce capable of being grown in the country. The
navigation of the Volta river and the two main branches seems to
suggest a means which might be employed, for, although there are
several rapids in the course from Daboya and Bole to Labolabo,
only one is impassable for canoes, even in the dry season. This
rapid is at Krachi where a short line has been laid for transporting
loaded canoes. The cost of the hire of canoes for making the journey
would probably be prohibitive, but if the British Cotton Growing
Association undertook the carriage by their own canoes of the salt
and stores required by the merchants who have commenced business in
Yeji and Tamale, the freight on these in the journey upwards would
probably be found to cover the cost of bringing cotton down-stream,
and the export trade in it could be developed in this manner. The
British Cotton Growing Association made an effort to act upon the
suggestion made here, but discontinued their operations in July 1916,
when they handed over their buildings, at Tamale, to the Government,
as it was shown that under the existing conditions and with but one
European representative to further its interests, cotton-growing
in the Northern Territories could not hope to become a remunerative
export business (Colonial Reports, Northern Territories, G.C. 1916,
No. 956). The irregularity of the rainfall is a matter which must be
borne in mind in any future attempts to develop the industry here,
but the possibilities of providing artificial irrigation should not
be overlooked, as large tracts of flat land exist near the White
Volta river capable of becoming fertile under proper irrigation
and drainage.
=Other Field Crops.=—Yams are grown as a primary crop on mounds,
and three different kinds are common, probably referable to
_D. alata_, _D. sativa_, and _D. colocasiæfolia_, the last being
what is termed the water yam and the first the winged yam. Guinea
corn is the most important food grain grown, but millet is sometimes
planted. A red species of sorghum (_S. guineensis_, var. _robustum_)
is cultivated on a small scale for use in staining leather, but is
not used for food. Rice (_Oryza sativa_) is grown in the vicinity
of the large rivers, but is said to suffer damage from elephants and
hippopotami. The variety seems to be similar to the red rice grown in
the Gambia and Sierra Leone. Very little maize is planted, but some
is grown near Salaga. Cassava is only seen in the south near the
forest boundary, and groundnuts are not plentiful, owing, perhaps,
to the fact that cooking oil is obtainable from shea butter trees,
which are common in a wild state. Pigeon peas are often planted
round the borders of fields, and are left to yield more than one
crop. This pea is identical with one of the common “Dhalls”
of India (_Cajanus indicus_); the origin of the introduction is
obscure. Small beans are grown as well as _Indigofera spp._ Sweet
potatoes, okra, capsicum-peppers, sorrel-hibiscus (_H. Sabdariffa_),
and the Fra-Fra potato (_Plectranthus, sp._, “Tumuku” of the
Haussas) are also grown.
=Fibre.=—Plants belonging to two species of _Hibiscus_ are
used for the extraction of fibre for the preparation of cordage,
the cleaned fibre being similar to jute. These plants grow, with
perfectly straight stems, to eight or ten feet in height, bearing
short thin branches with axillary flowers.
=Tobacco.=—The tobacco grown is used for smoking or the manufacture
of snuff in many parts of the Northern Territories, and is prepared
in a special manner. For smoking tobacco the green leaves are pressed
into small gourds until a quantity of juice exudes, the mass being
rolled in this until it assumes an oval form, in which it is sold
in the markets before drying. For snuff it is ground up between
heated stones until the requisite fineness has been obtained,
and is then mixed with a small quantity of the powdered seeds of
_Monodora myristica_. The tobacco fields are usually confined to
small patches near houses, and wood ashes as well as sweepings
are applied as a top dressing. This appears to be the only crop to
which manure or fertiliser is given. The leaves always seem to be
stripped off the stems at one operation, whereby old and immature
leaves are mixed with mature.
=GUMS.=—Two species of _Acacia_ (_A. arabica_ and _A. Sieberiana_)
are found, especially in the uninhabited tracts in the centre of
the country, and the last named appears to yield a large flow of
gum, which, however, is not collected. Examination of this at the
Imperial Institute has shown it to be about equal in quality to
inferior Sudan grades; _A. arabica_ does not seem to yield gum with
such frequency in this locality as elsewhere. _Burkea africana_
and _Pseudocedrela Kotschyi_ produce a quality of gum comparable
with “Talh” from the Sudan. (Cf. _Selected Reports from the
Imperial Institute_, Pt. II., Gums and Resins, pp. 153, 165-7.)
=WOOD OIL.=—By cutting deeply into the base of a tree known as
“Neou” (Dagomba), and “Kawa” (Haussa), a rather copious flow
of resinous liquid is induced, which, when solidified, is a resin
somewhat similar, but inferior, to copal. The tree from which this
is procured is botanically known as _Daniellia thurifera_, Oliv.,
and the so-called “oil” obtained was at one time shipped from
Northern Nigeria under the name of African Balsam of Copaiba. It
is used in the Northern Territories for lighting purposes,
as well as medicinally. The tree yields a handsomely grained
timber. (Cf. _Bull. Imp. Inst._, 1915.)
=SHEA BUTTER.=—A tree known botanically as _Butyrospermum Parkii_
bears a fruit, from the kernel of which this valuable vegetable
fat is procured. The fat forms the cooking oil of the ultra-forest
country, taking the place of palm oil in this respect. The mode of
preparation in the Northern Territories is, doubtless, similar to
that employed in Northern Nigeria. The prepared butter is one of
the products carried by the Haussa traders, who visit Ashanti for
the purpose of purchasing kola, and is much appreciated in Kumassi,
where it obtains a high price. A small quantity is carried down
the Volta river by the canoes which bring salt from Adda to Yeji
and Daboya. An analysis made at the Imperial Institute of Shea
butter from the Northern Territories showed that the material is in
no way inferior to the better-known “Shea butter” of Northern
Nigeria. Cf. _Bulletin of the Imperial Institute_, vol. vi. (1908),
p. 370.
=RUBBER.=—Recently some species of _Landolphia_ were found growing
in the district of Wa and elsewhere, and, upon examination, one
of these proved to be _L. owariensis_, P. Beauv. This was at first
thought to occur plentifully, and to assume the underground habits of
_L. Thollonii_, one of the most important sources of root or rhizome
rubber in the Congo. Specimens, which were found growing near the
south bank of the Black Volta river, in grass land, exhibited a
trailing form of growth owing to the absence of supporting trees,
but, although the plants were probably dwarfed by the annual grass
fires, no development of root growth was observed in excess of that
ordinarily produced within the forests. The plant is now reported
to occur rather rarely in the Northern Territories; another nearly
allied, though useless, species having been mistaken for it.
=DYES.=—For dyeing the yarn made from the native cotton, indigo
is made from a species of _Indigofera_, or from the young leaves of
_Lonchocarpus cyanescens_, but the process of preparation employed
in this country has not been carefully observed. It is, however,
probably similar to that in common use in Sierra Leone, Northern
Nigeria, and the Gambia.
=BEESWAX.=—Bees are attracted to hive in calabashes placed in
trees, the honey and wax being taken from them and sold in the
markets. The bee belongs to a small variety of _Apis mellifera_,
known as var. _Adansonii_. A sample of beeswax obtained at Tamale
was examined at the Imperial Institute, and proved to be of excellent
quality and worth £6 15_s_. per cwt. (Dec. 1908).
=LEATHER.=—Tanning of sheep and goats’ skins is done to a small
extent, the same process as that described for the preparation of
Kano leather in Northern Nigeria being followed. The _Acacia_ pods
used for the purpose are obtained from trees often found planted
in the middle of towns.
=CATTLE AND POULTRY.=—A large breed of cattle with a dorsal hump
exists in the Salaga district, and a straight-backed smaller kind
throughout the country to the north. Although “tsetse” flies
of three species are common on the stream banks, the cattle seem
to be healthy for the most part, and often form part of a caravan
travelling to the forest belt, where a good price is said to be
obtained for them from the Ashantis. They are usually killed for
food very soon after entering the forest, where they can no longer
be kept free from the attacks of the three species of “tsetse”
(_Glossina morsitans_, _G. palpalis_, and _G. pallidipes_), all of
which seem to attack them. Horses are bred in some parts, but not
to a large extent. Wire-haired sheep and goats are seen everywhere,
and can be obtained in many places at a low price.
Fowls and Guinea-fowls are reared in several villages, and are
carried to the south for sale. Long open-work baskets are used,
and the fowls are usually conveyed as head-loads. Guinea-fowls,
purchasable for threepence each in some of the villages south
of Daboya, are sold at four or five shillings each near the
coast. No coops seem to be employed in the villages to confine the
guinea-fowls, which habitually roost upon the house-tops and which
may frequently be seen in the adjoining fields. They are scarcely
distinguishable from the wild birds which occur usually in the same
localities. There is, however, a marked tendency on the part of the
domesticated examples to acquire white feathers upon the breast or
wings to a greater or lesser extent.
It should be recorded that a considerable local trade is carried
on in the country in the sale of a flour-like substance obtained
from the interior of the pods of _Parkia filicoidea_. This is made
up with the seeds of the plant into an edible paste, locally termed
“Dawadawa.”
=EXPORTS.=—Excluding cocoa, which is treated separately in its
place, the following table shows the progress of the export trade
between 1910 and 1919:—

=NIGERIA-SOUTHERN PROVINCES=
=INTRODUCTORY REMARKS.= =Administrative Divisions.=—On January
1, 1914, the countries, hitherto administered separately under the
names of Northern and Southern Nigeria, were amalgamated and placed
under a Governor-General. It is, nevertheless, convenient, from
the point of view of their agricultural and commercial interests,
to deal with them in this place separately. The inhabitants of the
Northern and Southern Provinces are to a very large extent dissimilar
in languages, religion and customs, and the climatic conditions,
by which distinct varieties of life are so much influenced, are so
suitably defined by the artificial boundary which, until recently,
divided Northern and Southern Nigeria, that little excuse need be
offered for the maintenance of old division in the discussion of
the subjects within the competence of this book. Following then the
plan adopted in the first edition, Southern Nigeria, referred to now
as the Southern Provinces, is being first dealt with and treated,
as far as possible, independently of Northern Nigeria, now entitled
the Northern Provinces, the separate account of which follows.
=Geographical Position.=—Pending the adjustment of the eastern
frontier, occasioned by the outcome of the recent war, the Southern
Provinces of Nigeria extend from 2° 45′ E. to 10° 15′ E. long.:
the Western Province reaching 9° 10′ N., and the Central and
Eastern about 7° 15′ N. lat.
=Area and Population.=—The estimated area of the country before
adjustment was 94,000 sq. miles, and the census of 1911 showed the
population as 7,857,983.
=Natural Divisions.=—The Southern Provinces are conveniently
divided for agricultural considerations into _wet_ and _dry_
zones. In the former the rainfall ranges from about 90 inches
at Bendi to 250 inches at Opobo. In the latter zone the highest
rainfall is reached in Lagos Town, where about 75 inches are
annually registered; the lowest reading being that of 40 inches
at Olokemeji. The densely forested area is practically entirely
within the wet zone; this also including a tract of brackish-water
forest (mangrove) and swamp. In the dry zone grass-land and open
“bush,” with trees peculiar to such localities, occur, and it
is in this portion of the country that most of the agricultural
people are found. The inhabitants of the forested area in the wet
zone give more attention to the collection of forest products,
such as palm oil and rubber, and only grow sufficient grain and
roots for their own consumption.
=Inhabitants.=—The tribes found in the Western Province are chiefly
Yorubas, and among these are some of the most intelligent people
in the country. In the Central Province there are a large number of
tribes speaking different languages, but among these the Benis are
perhaps of most importance. The Ijoas, Ibos, Aros, and many other
tribes inhabit the Eastern Province, and are generally of a lower
grade of civilisation than the others mentioned. The country between
the northern part of the Cross river and the Niger is populated by
other pagan tribes, who seem to be careful cultivators, but very
little is known of them at present.
=Cultivation.=—The Yoruba race are industrious cultivators, and
show considerably more ambition than most of the other West African
peoples. The country in which they live is particularly adapted to
farming, and the climatic conditions are suitable for the cultivation
of cotton and fibrous plants, in addition to the various grain
crops. In some parts cocoa, rubber, and kola are being cultivated,
but these are not so suitable under the prevailing conditions as
they would be within the wet zone—the Western Province, which
these people inhabit, being entirely within the dry region.
Although farming is so extensive, continuous cultivation is not
found, and the use of manure is practically unknown. The usual
practice is to farm a piece of land for a few years, and to permit
it then to return to a wild state for a long period. In their want
of knowledge concerning the value of manure and the application of
artificial irrigation, the Yoruba farmers are behind the Haussas
of Northern Nigeria, but are more careful than the Nupes of the
same country. The depth of the Yoruba cultivation is greater than
that of the northern Haussa, and this in some measure compensates
for the non-employment of manure, etc.
The people of the Central Province are generally less careful in
their farming methods; the Benis often planting their grain crops
in only partially cleared land. Farther to the north in the same
province a better system is noticeable among the Ishans, Ifons, and
the people of Agbede. During recent years, owing to the energetic
efforts of the Forestry Department, the cultivation and better
treatment of the indigenous rubber tree (_Funtumia elastica_)
have been extensively adopted, especially by the people in the
neighbourhood of Benin City, where the climate is well suited to
the species. In addition to rubber, cocoa and kola plantations
might prove successful in the same localities, but as yet no large
plantations of either exist.
In the Eastern Province farming is generally of poor quality until
the region of heavy rainfall is left, when extremely large areas
are met with, highly cultivated, with the earth thrown up into
loose mounds, often five or six feet in height, for the purpose of
growing yams, maize, pepper, okra, Guinea corn, pumpkins, etc.,
all of which are found planted upon each mound; the yams being
carefully trained to climb along fibre strings towards central poles.
=Principal Crops.=—The chief crops grown in the Western Province
are maize, cotton, cassava, yams, sweet potatoes, groundnuts, and
to a small extent Guinea corn, sugar-cane, tobacco, Colocasia yams,
peppers, okra, rice, eggplant, and native beans.
Indigo is extracted from _Lonchocarpus cyanescens_, which occurs
in a wild state, and is preserved when making clearances for
farms. The _Indigofera spp._ are used to a smaller degree for the
same purpose. (See Sierra Leone Section, p. 39; also _Bulletin of
the Imperial Institute_, 1909, p. 319; 1918, p. 11; and 1919, p. 31.)
Fruits are not grown plentifully, and are generally left in an
uncultivated condition. The chief kinds are pineapples, bananas,
pawpaws, akee apple (_Blighia sapida_), oranges, and guavas. There
are several fruits and spices which are collected from the forest
strips, but, taken generally, the Western Province people are
not great fruit eaters. On the sea coast and for a considerable
distance inland, coconut plantations are common, and, near Badagry,
copra is prepared from them for shipment.
The crops cultivated in the Central Province are similar to
those of the Western, but yams become more, and groundnuts less
prominent. Large quantities of palm oil are prepared, and rubber is
collected, the labour available for farm work being thereby reduced.
The most important product of the Eastern Province is undoubtedly
palm oil, but fairly large quantities of yams and maize are grown
outside the forest zone and are transported by native canoes to
the coast ports, in the vicinity of which there is very little
cultivation.
With the exception of the oil palm, which is of general
occurrence throughout the country, the Lagos silk rubber tree
(_Funtumia elastica_) is of the most importance from a commercial
standpoint. Rubber vines of the genera _Landolphia_ and _Carpodinus_
are also valuable wild plants, from which some of the finest
rubbers are at present extracted. Copal, known as “Ogea” gum,
and collected from a tree which has been determined as _Cyanothyrsus
oblongus_ (syn. _ogea_), is exported in varying quantity according
to the market value. A fairly extensive local trade is done in
“chew-sticks” in the Western Province; the sticks being cut
from a tree which occurs in the grass country, and is recognised
as _Anogeissus leiocarpus_. The ash made from the wood of the same
tree is sold for use as a mordant in indigo dyeing. Camwood is
a red dye-wood prepared from at least three different species of
trees—_Baphia nitida_, _Pterocarpus tinctorius_, and _Pterocarpus
sp._—and is almost entirely used locally for staining the human
skin or dyeing leather. Fibre plants do not appear to be cultivated
in any part of the country, but occur to some extent in all the
forested parts. _Hibiscus guineensis_ and _Dombeya buettneri_
are usually employed for native ropes, and the bark of _Sterculia
barteri_ is said to be prepared for the same purpose.
=OIL PALM.=—A description of this tree and information in
connection with the principal characteristics and mode of propagation
have been given in the Sierra Leone portion of this work, and it
may merely be remarked that there is no difference in a general
way between trees grown in the two localities. With regard to the
form of fruit, however, that of Southern Nigeria is separated into
several kinds, varying in the relative proportion of pericarp and
kernel, and these will be referred to later.
The method of preparing palm oil varies to a large degree in the
different localities. The best quality of oil is that produced in
the Western Province. The oil, which on the market is classed as
“Lagos fine grade,” and obtains the highest price among West
African oils, is made from the fresh fruits boiled and pounded in
the manner described for the Sierra Leone oil, but the extracted
oil is further cleared by straining and boiling until a uniformly
clear and limpid product is obtained.

[Illustration: AFARA TREE (_TERMINALIA SUPERBA_) AT OLOKOMEJI.
Fig. 24, p. 118.]
An inferior quality is that made at Oshogbo and north of Ibadan
generally. The fruits, after having been boiled for about three
hours, have the fibrous pulp sufficiently loosened, so that the
whole is easily separated from the nuts by pounding in a wooden
mortar. The fibrous mass thus obtained is then put into a pit, which
is filled to a depth of about eighteen inches with cold water, and
the oil is expressed by women and young girls, who tread it out with
their feet. After leaving the water undisturbed for a short time,
the oil rises to the surface, from which it is skimmed, or it may be
precipitated, by the removal of a plug placed in the side of the pit,
into a vessel placed to receive it. The treading process is repeated
until most of the oil is extracted. The oil is then separated from
the water which it contains by boiling. The fibrous pulp is next
removed, strained in baskets, and is placed upon rocks to dry in
the sun, after which it is pressed into large balls, which are sold
in the local markets at 1_d_. each. Much of this finds its way to
Lagos Town, where it is sold for fuel at the rate of 8_d_. for 8½
lb. In this connection it may be mentioned that there appears to be
no foundation for the statement which has been made to the effect
that this residual pulp is exported in large quantities from Lagos
for the further extraction of oil by chemical means in Europe. An
illustration is given showing a girl straining fibrous pulp in an
oil pit at Oshogbo (Fig. 22).
In the Central and Eastern Provinces “hard” oil is the
commercial name applied to the kind which is generally made. At
Onitsha the natives may be seen bringing in this oil, which is of
such a consistency that even at an atmospheric temperature of 90° it
remains in a solid wax-like condition. The earthen vessels in which
such oil is conveyed to the factories, when accidentally dropped
and broken, do not necessarily occasion the loss of any oil. The
thickened condition is entirely due to the method of preparation,
during which important chemical changes occur, which appear to
be detrimental to the oil for some of its most important uses,
especially that of soap manufacture, while rendering it suitable
for employment for making candles. The important difference in the
preparation of this oil lies in the fact that instead of the fresh
fruits being used, the pericarp is separated from the nuts by means
of partial decomposition, induced by burying the fruits in the
ground for a period varying from three weeks to two months. The
semi-decomposed pericarp is then easily removed by pounding or
treading out in a canoe-shaped receptacle, after which the fibrous
mass is boiled, and the liquid oil is skimmed and allowed to set
in earthen jars, in which it is carried for sale to the factories.
The extraction of kernels from the nuts is one of the usual
occupations of the women and children of a village, when not
assisting in the preparation of oil. The nuts are spread in the sun
for about a week or more until a shrinkage of the kernel occurs,
which renders the nut-shell capable of being easily cracked without
damage to the interior. It is said that in the Jebu district, to
the north-east of Lagos, the local price paid for kernels ranges
from 4_d_. to 4½_d_. for a filled tin bowl having the diameter of
nine inches.
The primitive method of extracting kernels, by means of cracking
the nut-shell between stones and picking out the contents, has not
yet given way to the employment of the various machines which have
been introduced from time to time to supersede it.
A black oil is extracted at Oshogbo by roasting the kernels in an
earthen pot until black, and stirring meanwhile until the whole mass
becomes covered with exuded oil. A small quantity of cold water
is then sprinkled into the pot after removing it from the fire,
and the contents are pounded in a mortar until an oily meal is
produced. This is boiled, and, when the mixture is cool, the oil
is skimmed from the surface of the water which has been added for
the boiling. This oil is apparently only used locally.
The existing native social system, under which the male head of
a family receives almost exclusive consideration, is opposed to
native co-operation in any mechanical process, whereby a relief from
labour of his numerous dependants—wives, children, and aged or
infirm relatives—would be incurred at the expense of his enhanced
personal labour; he being the carrier and disposer of the produce at
the market. By the conveyance and sale of nuts instead of kernels,
a much smaller return in value would be obtained for the same
weight of material, _i.e._ a similar amount of personal energy. The
dependants, incapable of assisting in transporting, would remain
idle, unless some similar work could be found for them. Up to a
short distance from the delivery point (which would determine itself)
the nuts instead of the kernels would be brought in for sale, and,
limited by the capabilities of the available palm-tree climbers,
the family dependants would be able to prepare larger quantities
of pericarp oil; but the increased accumulation of kernels would
further decrease the radius from the selling centre at which the
carriers would be able to work.
If the entire fruit were to be bought up for mechanical extraction of
pericarp oil as well as kernels, the carrying labour would be still
further enhanced, and the work of the oil-manufacturing communities
would resolve itself into three operations—viz. climbing trees,
chopping out fruit, and transporting—which would mean the exclusion
from work of all but the strong adults, or the reduction of workers
by 30 to 50 per cent. perhaps. The number of skilled palm-tree
climbers is said to be decreasing in many districts, and, owing
to the sparsity of the population in some localities, a very large
proportion of the annual yield of fruit remains unharvested.
The investigation of the several varieties of the oil palm of the
country is in progress at the Imperial Institute, and the characters
of the most important are now well known, and may be compared here
with the varieties from the Gold Coast, Sierra Leone, Gambia, and
Northern Nigeria. The typical form, which, although subject to some
variation, possesses certain marked characteristics, may be said
to fall under the following general description:
Fruiting heads generally large. Fruit large, orange to scarlet
in colour, with a variable amount of purplish black suffusion
at the apex, which may extend over more than half of the fruit
or may be altogether absent. Pericarp thin, kernel large with a
thick shell. Names: “Ope yope” or “Ope pankora” (Yoruba),
“Ok-poruk-pu” (Ibo), “Udin” (Beni), “Ak-porro-jub”
(Efik), “Irök-Eyop” (Ibibio), “Abe pa” and perhaps “Abe
dam” (Fanti, Gold Coast), “Tug bore” (Mendi, Sierra Leone),
“Tabel-tiloli” (Timani, Sierra Leone), “Tengo” (Mandingo,
Gambia), “Kabe-kalako” (Jolah, Gambia), “Neul” (Joloff,
Gambia), “Qua-qua” (Haussa, N. Nigeria), “Yi-ku-niche”
(Nupe, N. Nigeria). Only the typical form has as yet been observed
in Sierra Leone, Gambia, and Northern Nigeria.
The other particularly important variety is that commonly referred
to as the “_soft-shelled_” or “_thin-shelled_” palm fruit,
which has been recorded from many localities in West Africa. The
following description will include the forms contained in this group:
Fruiting heads often large. Fruits large or small, generally the
latter, dark coloured. Pericarp thick, kernel rather small, with a
thin shell. Names: “Ope-Arunfo” (Yoruba), “Au-su-ku” (Ibo),
“Ivioronmila” (Beni), “Asoge-e-jub” (Efik), “Eduege Eyop”
(Ibibio), “Abe-bobe” (Fanti, Gold Coast).
The third kind is that frequently called the “_Fetish_”
or “_King_” palm nut. It is rare wherever it occurs, and is
scarcely worth consideration from an economic standpoint. The tree
which bears this fruit has been described under the distinct specific
name of _Elæis Thompsoni_, Chevalier.
Fruiting heads generally small. Fruits medium-sized, red with
black markings occasionally present. Pericarp moderately thick,
kernel and shell medium. The nuts, which possess four eyes, are
not used in the manufacture of commercial oil, but are employed in
connection with the worship of the deity Ifa (Dennett). Names:
“Ope Ifa” (Yoruba), “Ojuku” (Ibo), “Oged-udin”
(Beni), “Affia-ko-jub” (Efik), “Efiako-Eyop” (Ibibio),
“Abe-ohene” (Fanti, Gold Coast).
The above are the three most marked forms of oil palm recognisable,
although other varieties are given special names by natives in
different parts of the country, distinctions being frequently made
between the fruit from trees which assume a tall growth and those
which remain stunted. (Cf. also _Bull. Imp. Inst._, 1909, p. 362;
and 1920, p. 223.)
As far as investigations have progressed, the advantage with
regard to yield of oil as well as quality is maintained by the
thin-shelled variety, the greater proportion of pericarp enabling
a larger amount of pericarp oil to be expressed, while the thin
kernel-covering facilitates the extraction of the kernel. Before
being able to definitely state that this variety is of the greatest
economic value, it is necessary that a comparison of the weight of
the annual crops from all varieties should be made.
The advisability of planting any particular variety of oil palm would
in the first place depend on the results obtained from the complete
investigation of all; but at the present time such a project on a
large scale is not likely to be practicable, as it is generally
acknowledged that only a comparatively small proportion of the
existing wild trees are at present utilised.
Experiments in the Kamerun, with different varieties of oil palms,
seemed to indicate that the thin-shelled character was not a fixed
one. In 1910 a forest officer in Nigeria was detailed to study the
distribution, cultivation and preparation of the oil, of the most
appreciated varieties, and a quantity of nuts of the soft-shelled
“Lisombe” kind from the Kamerun were distributed for planting
among the natives of the Eastern Province.
The export figures of this trade from 1910 to 1918 are tabulated
below. Up to the year 1914, those of Northern were separated from
those of Southern Nigeria. In this account, subsequent to that year,
the two sets of figures have been taken together. A quantity of
kernels is imported from Dahomey for re-export, amounting in 1910
to 21,120 tons. The figures indicate that the increase has been
irregular, and, during the last few years, has been influenced
by the war. In 1919 here, as in the other W. African Colonies,
a differential export tax of £2 per ton was imposed, with respect
to palm kernels.
Year Palm oil in tons Palm kernels in tons
(280 galls. = 1 ton)
1910 76,850 172,998
1911 79,337 176,390
1912 76,994 184,624
1913 83,088 174,718
1914 72,531 162,452
1915 72,994 153,319
1916 67,422 161,439
1917 74,619 185,998
1918 86,425 205,167
1919 100,967 216,913
It is interesting to compare the amount of oil produced in
proportion to kernels collected, there being a marked difference
in this respect between the output of the Western Province (Lagos)
and the Central and Eastern Provinces. A previous series of thirteen
years’ exports from the former showed an average of 60·9 gallons
of oil to the ton of kernels; while for the latter a twelve-year
period at the same time gave 219·6 gallons of oil to the ton of
kernels. The mean for the whole was 140·25 gallons at that time,
but during the last seven years it has fallen to 125·7 gallons. In
1912 the first shipments of kernel oil and cake were made from
factories established under European control at Opobo and Lagos,
the amounts exported being 500 tons of oil and 635 tons of cake. In
the following year the value of both products turned out by these
factories is given as £161,000, and in 1914 as £72,000, when,
without any assigned reason, both factories were closed down.
Articles on the African palm-oil industry in the Southern Provinces
of Nigeria will be found in _Bulletin of the Imperial Institute_,
1909, 1911, 1912, 1913, 1914, 1915, 1919.
An interesting article appears in the _Bulletin of the Imperial
Institute_, vol. xviii., No. 2 (1920), entitled “The Cultivation
of the African Oil Palm, with special reference to the East
Indies.” From this it appears that the tree thrives and yields very
satisfactorily, especially in Sumatra; the oil content of the fruit
and kernels being both high. Attention is drawn in this article to
the extension of the use of palm oil in Europe as an edible fat,
in addition to its present uses.
=Other Oil Seeds.=—Excluding the shea nut tree, which will be
referred to later on, three trees have been considered of sufficient
importance for their seeds to be shipped to Europe in order that
their value may be determined. These are _Pentaclethra macrophylla_
(Cutlass bean), _Irvingia Barteri_ (African mango), and _Lophira
alata_. Although the trials proved that the oils of all might be
valuable for the manufacture of soap and candles, none of the trees
occur in sufficient profusion to permit a large export trade in the
seeds being established. (See _Bulletin of the Imperial Institute_,
vol. v. [1907], pp. 10-14, and vol. vi. [1908], pp. 243, 354-80.)
=RUBBER.=—Following the progress made by the Forestry Department
in re-establishing the indigenous rubber tree (_Funtumia elastica_)
in places from which it had almost disappeared, an excellent system
of communal plantations was established. This system, which has
been largely adopted by the chiefs, is one to encourage the village
inhabitants to re-establish rubber trees in their proximity; the
planting and tapping and preparation of the rubber being under
the direction of the Government officers. The resulting rubber is
marketed by the Government, who retain one-third of the sale price
to cover the cost of supervision, etc.; the remaining two-thirds
being paid to the village community. In this manner a large number of
communal plantations have now been established. In 1911 over 400 new
plantations of this kind were made; about 100,000 Funtumia plants
being put in. At the same time 129,000 Para rubber seeds and some
4,000 seedlings were distributed under the same scheme, while Ceara
plantations were made in the drier parts of the country. Licences
to collect wild rubber were simultaneously made compulsory.
The rubber produced on the Government plantation at Mamu Forest,
by the boiling method, proved very satisfactory. In 1910 such rubber
was sold at 6_s_. 6_d_. per lb., being only 6_d_. less than the best
Para fetched at the same time. Three hundred communal plantations
yielded rubber in 1911 against eighty-four in the previous year,
the average yield per tree being 1·59 oz. against 1·406 oz. In
1912 communal rubber amounted to 3,031 lbs., which sold at about
3_s_. 4_d_. per lb.; and in the same year Government plantation
rubber was 3,501 lbs., which realised 3_s_. 10_d_. per lb.
The next rubber plant of importance is the vine, _Landolphia
owariensis_, which is somewhat variable in the form of growth. The
latex at certain seasons coagulates almost instantaneously, but at
other times it runs freely, and can be collected for coagulation by
heat, the admixture of acid, alkali or alcohol, or by spontaneous
exposure. The scrap rubber, which is collected from that coagulated
upon the stem, is made into balls, and comes into the market under
the name of “first Niggers,” and commands a high price.
The native has discovered that a larger amount of rubber can be
obtained at one time if the roots and stems are cut and pounded
up. The result is a product known as “root rubber,” the
collection of which can be justified only where the plant, from
which it is obtained, develops an extensive rhizome or subterranean
growth, capable of being partially removed without killing the
plant. Such vines, although found in some other parts of Africa,
do not occur in Southern Nigeria, and the collection of so-called
“root rubber” from _L. owariensis_ only leads to the complete
destruction of the plant, and should be discouraged. The small
yield of latex from this species after many years of growth, and
the difficulties in connection with the collection of the rubber,
render its cultivation in plantations unprofitable, although planting
has been attempted in the French and German Colonies.
_Clitandra elastica_ is another vine said to yield a copious supply
of latex, capable of being coagulated by means of heating after
dilution with water. In appearance the vine is somewhat similar
to _L. owariensis_, but does not appear to be common. The rubber
produced from this species is reported to be of excellent quality.
_Carpodinus hirsutus_, a common vine in the dry zone and on the
Niger river banks, furnishes a plentiful supply of latex of inferior
quality, and is made into “root” and “paste” rubber by
boiling; the latter being a sticky product of the consistency of
birdlime, and only saleable in Europe at a low price.
The latices of _Landolphia Thompsonii_ and _L. senegalensis_ are
used similarly. Both species are nearly allied to _L. florida_,
which is prepared elsewhere.
A number of latex-yielding plants are employed in the adulteration
of good rubber, among which the following may be mentioned as
the commonest: _Funtumia africana_, _Conopharyngia sp._, _Alstonia
congoensis_, and _Holarrhena Wulfsburgii_. The admixture of these is
usually detected by the stickiness which they impart to good rubber.
The introduction of licences for permission to collect wild rubber
and that of the communal plantation system, previously referred
to, have rendered the position more secure than previously, and
insured the preservation of the wild plants which were threatened
with extinction. This has moreover been effected in the most
economical manner.
The results of the tappings on the Para rubber plantations in
different parts of the country are of interest. In 1911 at Ebute
Metta, trees eighteen years old yielded 3 lbs. 5½ oz. per tree;
at Calabar six year old trees gave an average of 6 oz. per tree;
while at Sapele in the same year, five year old trees yielded
from 14 oz. to 1 lb. 6½ oz. per tree. In the following year the
same trees at Ebute Metta gave 7 lbs. 4¾ oz., while those at
Sapele yielded from 1 lb. 4¾ oz. to 1 lb. 11¾ oz. In 1915 from
two Para rubber estates at Sapele 94,413 lbs. of dry rubber was
harvested. (Cf. _Bull. Imp. Inst._, 1910, 1912, 1913, 1918.)
=Export of Rubber.=—The Commercial Intelligence Officer of Southern
Nigeria, in his report on the trade of the country for 1907, gives a
table showing the rubber exported from Southern Nigerian ports from
1900 to 1907; but as these figures include large quantities of the
product from Northern Nigeria, shipped through Southern Nigerian
ports, they do not represent the output from the latter country
alone. Until 1907 apparently no record of the Northern Nigerian
rubber exported was kept, but in the year mentioned 1,187,588 lbs.,
valued at £91,074, were recorded as having passed the customs post
of Northern Nigeria at Ida, on the Niger. The amounts, in tons,
exported from the Southern Provinces alone were: 1907, 690; 1908,
545; 1909, 620; and from the whole of Nigeria from that time: 1910,
1,180; 1911, 966; 1912, 705; 1913, 510; 1914, no figures; 1915, 248;
1916, 396; 1917, 392; 1918, 157; 1919, 398. The rubber production
of the country is to some extent controlled by the market price,
which is at present very low (1921).
=COPAL.=—Some quantity of a kind of copal resin is collected from
_Cyanothyrsus oblongus_ (syn. _C. ogea_), and is exported under the
name of “Ogea gum.” The quality appears to be similar to that
obtained from the Gold Coast _Cyanothyrsus sp._, and which is sold
under the name of “Accra copal.” Both are obtained in a fresh and
a fossil state. Owing to the recent fall in the price of ogea gum,
the collection of it has diminished, but there are said to be large
quantities available which would be collected as soon as a better
demand occurred. (See articles on “Copal Resins from British West
Africa,” _Bull. Imp. Inst._, 1908, p. 245; and 1914, p. 218.)
=COCOA.=—The good fortune which has recently attended the planters
in West Africa, owing to a sudden demand for their cocoa, has
encouraged them, especially to the north and north-east of Lagos,
to make more extensive plantations. The climatic conditions in the
Western Province, however, are not favourable, and the repeated
failures of trees, due to the exhausting effect of the long dry
seasons, give the plantations an irregular appearance. The trees in
the plantations made at Agege, where many well-to-do planters have
made farms, are stunted, and planted in too close proximity, mostly
without permanent shade trees. In some instances the trees showed
disease from the sapping of the bark juices occasioned by a Capsid,
the species of which is as yet undetermined. The chief cause of their
sterility and death seems, however, to be the unfavourable climatic
conditions. In the direction of the Abeokuta-Ibadan boundary, better
planting seems to have been done and permanent shade trees preserved.
It is said that the Agege planters are dissatisfied with the
prices they obtain for their cocoa, which they maintain is properly
fermented and of better quality than that of their neighbours. An
association of the local planters was recently formed to ship
their own produce direct to the European markets. The Agege cocoa
generally, however, does not appear to be more carefully prepared
or of better quality than the other local kinds. Fermentation
is certainly practised in many places, and is becoming popular
throughout the Western Province, owing to the discovery that the
fermented pulp juice forms a beverage, which is said to be used as
a substitute for palm wine, but the beans are frequently improperly
dried.
In the Eastern Province the climatic conditions appear to be more
favourable for the plant, and there are now a number of small
plantations near Eket, Old Calabar, and Itu. The product is still
improperly prepared and usually unfermented, but time and experience
will remedy this.
In the Central Province from 1915 some activity in cocoa planting
has occurred in the Benin district, but attention there is still
mainly devoted to rubber planting.
See also _Bull. Imp. Inst._, 1914, p. 213; 1915, p. 553; and 1919,
p. 289.
The exports of cocoa have been as follows:

=COTTON.=—Reviewing the work which has been done in inducing
the agricultural population of the country to cultivate cotton for
export, by far the greatest prominence must be given to the untiring
efforts of the British Cotton Growing Association, who are gradually
surmounting all the obstacles which retarded their progress. The
condition of the industry, especially in the Western Province,
is extremely favourable, and shows signs of further development.
In every Yoruba market sales of cotton are now conducted as a part
of the regular transactions of the day, and cotton from distant
villages filters through from market to market, increasing in
value as it approaches a ginnery, where the full price for it may
be ultimately claimed by the trader who has collected it.
On account of this system of passing from one market to another,
chiefly in the form of barter for other produce, it becomes nearly
impossible to accurately determine the origin of the supplies
brought to the ginneries; and, by reference to the records kept,
very large quantities of cotton often appear as having been sent
from towns which are little more than accumulating centres, and in
the vicinity of which there is little or no cotton grown.
Experience in the plantation of cotton under European control has
shown that without combining the work of a general trader, farmer,
and ginner with that of grower, such an attempt is not likely to
prove remunerative. The British Cotton Growing Association have
abandoned development upon these lines, directing their attention
solely towards buying, ginning and inducing the native farmers
to cultivate the plant in their ordinary field rotations. Such
plantations as still exist are now under the direct control of the
Government and are maintained for the purpose of experimental work
and for the propagation of improved types.
The local varieties of cotton may be roughly classed under five
heads, which are easily recognisable by the characters of the seed
and lint. These are:
1. Black, clean-seeded with a brown tuft or brown woolly and a
brick-red lint.—“Eponkon.”
2. Black, clean-seeded, with a creamy white lint.—Common Western
Province kind; rarer in the Central Province (Ishan).
3. Black, adhering seeds, “kidney” kind, lint creamy.—Common
Central Province.
4. White or brownish woolly seeded, lint creamy.—Meko and Agbede
kinds.
5. Green woolly seeded, lint creamy.—Rather uncommon except
at Agege.
The characters of the above classes do not appear to be sufficiently
constant to render it easy to give each class a specific position,
although some of them are doubtless separable. All native forms of
plant are constantly of greater stature than American, and in this
particular resemble Egyptian kinds.
The red-linted form known as “Eponkon” is identical with the
“Dhoole” of Sierra Leone, and, although prolific, yields a cotton
which is of little value for export. The other four kinds are those
from which the Southern Nigerian output of exported cotton is almost
wholly obtained, and the price realised varies from ½_d_. under
to 1_d_. or more over Middling American. The finest cottons are
those grown at Agege and Meko; the former being supposed to be a
hybrid with an American variety, and the latter a constant local
variety. Some of the shipments, from Illushi, of cotton grown near
Agbede appear to have been of equally desirable quality.
A large number of specimens of cotton have been examined at the
Imperial Institute, and the length of fibre is generally found to
be over one inch in average, but the colour is yellowish, and there
is less lustre than is found in the American kinds. Although the
price obtained is often somewhat higher than that of the standard
Middling American grade, Manchester spinners do not regard West
African cotton as quite suitable for their ordinary requirements,
and it appears that the higher prices have only been paid for small
quantities which were capable of being used for special purposes.
For the reason mentioned, efforts have been made to replace
the indigenous cottons by American kinds, or to hybridise the
two, but the results have not yet been successful, the tendency
being to produce an irregular mixed lint, which is commercially
inferior. American and Egyptian cottons seem to be less capable
of withstanding the attacks of the local insect pests, and a
large proportion of the seed is rendered sterile by the cotton
seed bug. Grown experimentally on a small scale at Olokemeji,
the following results were obtained from several exotic and local
cottons (American Middling at 6·64_d_. per lb.):—

Of the above Nos. 1, 2, 8, 10, 11, 12, 14, 16, 17, 18, and 19
are American varieties, and were grown from seed supplied by the
British Cotton Growing Association; Nos. 4, 5, 6, 13 and 15 are
Egyptian; No. 9 is a Northern Nigerian variety from North Ilorin,
and Nos. 3 and 7 appear to be local kinds. These cottons are
referred to in Professor Dunstan’s Report (1907), “British
Cotton Cultivation.”
In addition to the susceptibility of the American varieties to the
attacks of the local insect pests, the seed produced from plants
grown in the country is often sterile. In the districts in the
vicinity of the British Cotton Growing Association’s ginneries
American and native cottons are often seen growing in the same field,
but as the time of reaching maturity differs in the various forms,
and the cotton is not easily kept separate in the native methods
of harvesting, a mixed crop is obtained. Experimenting at the
Moor Plantation at Ibadan, the British Cotton Growing Association
have obtained occasionally satisfactory results from the American
plots, as appeared to be the case in the 1908-9 season, when an
American “Upland” variety is said to have yielded 800 lbs. of
seed cotton per acre. In the previous year an indigenous variety
called “Meko” is recorded as having produced over 900 lbs. to
the acre. These results are largely dependent upon the season and
the time of sowing.
Artificial pollination of the female flowers of the local forms
with pollen taken from American kinds has not yet succeeded in
producing a permanent hybrid, although the result in the first
generation has frequently shown great promise. There is no doubt
that the establishment of a hybrid which would carry the lint of
the best American kind and retain the hardiness and blight-resisting
powers of the indigenous forms would be very desirable, but such a
type could only be evolved after careful experiment and selection
for a prolonged period. Such work may probably be undertaken
by the Agricultural Department in the future. Until this can be
scientifically taken up, the improvement of the existing forms by a
more gradual means should be attempted, namely by a careful selection
of seed and elimination of undesirable forms of plants in the field.
