POTTERY.—Earthen pots are made in several parts of the country, and are usually symmetrically formed, although no wheel is used in their preparation. The large earthen jars made at Abeokuta are used in the palm oil, native beer, and indigo industries.

FOREST RESERVES.—These are now being formed everywhere in order to replace the destruction of recent years. The irregular rainfall renders natural regeneration very poor, and artificial regeneration by means of planting by leaseholders for trees cut down has proved unsatisfactory. In 1913 some villages in the Central Province started small mahogany plantations, and trees for fuel are now being grown in several districts. The value of such trees as Afzelia africana and Triplochiton johnsoni has been recently demonstrated.

NIGERIA-NORTHERN PROVINCES

INTRODUCTORY REMARKS—Until 1914 the Northern Provinces of Nigeria were separately administered under the designation of Northern Nigeria, and were the largest as well as the most recent of our West African Colonies. They lie between 7° 3′ and 13° 54′ north latitude, and 2° 50′ and 14° 5′ east longitude, and are bounded on the north by the French Sudan, on the east by the Kameruns and on the west by Dahomey and French Guinea. The Southern Provinces of Nigeria almost completely adjoin the southern boundary.

The estimate of the populations and areas of the thirteen provinces given below is taken from the Colonial Office Report No. 821 for 1913:—

Area, sq. miles. Population.
Sokoto 32,600 1,300,000
Kano 29,500 3,500,000
Bornu 33,600 700,000
Central[5] 23,700 700,000
Zaria 13,320 402,000
Niger[5] 16,770 400,000
Kontagora 27,800 122,000
Ilorin 6,500 200,000
Muri 28,700 700,000
Nassarawa 16,710 600,000
Yola 11,600 300,000
Kabba 8,200 140,000
Bassa 6,700 205,000
255,700 9,269,000

The total population is thus nearly double that of the estimation of 1907-8. For convenience the Northern Provinces may in places still be referred to in this work by the old title of Northern Nigeria.

As will be seen below there is less variation in the rainfall of the different provinces than is found elsewhere in West Africa. The averages of the following centres for as many years as are available until 1913 are given for comparison:—

Av. inches. Av. inches.
Naraguta 50·28 Knepp 40·80
Ilorin 49·75 Yola 38·64
Kontagora 47·77 Kano 33·65
Zaria 46·59 Maifoni 27·85
Baro 46·56 Sokoto 24·86
Lokoja 45·77 Kataguni 19·87
Zungeru 41·67 Geidam 15·14

Of the places mentioned the highest single year’s rainfall was reached at Ilorin when 65·18 inches fell, and the lowest at Geidam in 1913 when only 5·76 were recorded. There are localities where the rainfall exceeds the highest given here and others where it is undoubtedly much lower, but no records are available. The highest shade temperatures have been at Dumjeri and Maifoni (North Bornu), where 120° was attained, the lowest being at Kano, where it fell to 39°. In Kano and Zaria rain seldom falls between November 1 and the end of March, but the distribution is more general in the south.

Administration and Political Divisions.—The administration of Northern Nigeria was taken over by the Crown in 1900, having previously been carried on by the Royal Niger Company. Protectorates were gradually assumed, and the country placed upon a secure footing by the suppression of raiding, which had constantly been carried on by the different Emirs, chiefly upon the pagan tribes. The devastation caused by these raids is still visible in the country to the south of Kontagora and elsewhere, and the fear of the raiders kept the inhabitants within or in close proximity to their walled towns, leaving large tracts of fertile country unexploited. The work accomplished by Sir Frederick Lugard, the first High Commissioner, was largely that of pacification and reassurance of the people, and until this had been completed, and facilities for transport provided, it could not be expected that the country could make much progress from a commercial standpoint.

The further opening up of the country by means of roads and railways, and the assessment of land revenue upon lines completely understood and recognised as fair by the natives, was effected by Sir Percy Girouard, who succeeded Sir Frederick Lugard’s first administration. Sir Frederick subsequently returned as Governor-General of the amalgamated Nigeria.

Until April 1907 the country was divided into fourteen provinces, one of which, Borgu, was absorbed in Kontagora at that time, making the thirteen mentioned above. By a later reconstruction the provincial limits of the two provinces of Bauchi and Nupe were reformed, and the provinces reconstituted under the names of the Central and Niger Provinces respectively. Groups of provinces were then placed under First-class Residents. Photographs are given of Kano and Zaria (Figs. 32 and 33).

Natural Divisions.—There is less apparent possibility of defining limits to the natural conditions of any part of the country than is found in the countries nearer the coast. There is no afforested zone in Northern Nigeria, although fairly densely wooded tracts occur in several places near the larger rivers. It may be said that grass land studded with well-separated trees is the condition of the country throughout, the trees becoming more stunted towards the northern and desert boundaries. To the north of the 11th degree of latitude, the botanical aspect becomes different; more trees of the Mimosa group, including the gum-bearing Acacias, becoming apparent. Cattle thrive well in this region, where the “tsetse” fly has not yet been observed.

Haussa Land, a term applied to the northern parts of the country, alone among the British West African territories, may be said to have been controlled by an ordered form of government from early times, and to have had a recorded history. Unfortunately these records were destroyed, wherever possible, by the Fulani conquerors, who came from the source of the river Senegal and overran the country at the beginning of the last century, and whose object seemed to be to endeavour to eliminate from the minds of the conquered people all recollection of their previous power. In spite of strenuous efforts in this direction, a few documents have been preserved, and these, combined with traditions, which have not had time to become completely distorted, show that, in spite of severe wars, famines, and other disturbing incidents, the Haussa has maintained his characteristic traits.

The origin of the Haussa race is still a matter of uncertainty, although there is some reason to suppose that it came from the east, and gradually penetrated the Western Sudan from the north. The Haussa language, which is claimed to be more in use than any other native language in West Africa, is said, by Lady Lugard, to be classed with Coptic among the Hamitic languages.[6]

History has established the fact that there were seven divisions or states in Haussa Land, the people of which, although regarded as having come from a common stock, were almost perpetually at war with one another. The mythical account of the formation of these states relates that each had particular duties assigned to it; those of Kano and Rano, to the north of Zaria, being specially industrial. At the beginning of the sixteenth century, when the Songhay kingdom was at the summit of its power, Kano and Gober, among other Haussa towns, were specially referred to by Leo Africanus on account of their cotton trade.[7]

Everywhere along the West Coast the name Haussa is associated with the idea of trade; the itinerant nature of the race inducing individuals to visit the remote parts of the pagan countries, thus creating trade routes in all directions. The Haussa trader of the present day does not necessarily bring goods from his own country for trading, but buys in one market to sell or exchange in another. It is by this means that many European manufactured goods penetrate into localities where no European trader has yet set foot.

The Haussa is also regarded as a good soldier, and is largely enlisted in the native regiments of West Africa under European officers.

The Nupes, Yorubas, Gwaris, Yauris, and others were constantly in contact with the Haussas, and to a small extent the Haussa language is spoken by them. Nupe is regarded as an ancient kingdom, occupying at one time a position of great importance. The Yorubas, who inhabit nearly the whole of the Ilorin Province and the Western Province of Southern Nigeria, trace their origin from the Phœnicians of the tribe of Nimrod, and claim that all the pagan tribes of Haussa Land are descended from them. The Gwaris, apparently, have no records, but are a scattered race living among the rocky hills and caves in the country lying to the south of Zaria.

Bornu was not evidently included in the Songhay kingdom or associated with the Haussa states, the inhabitants belonging to a distinct race with separate traditions. Their history in comparison with that of the Haussas is of recent date. In 1808, after the successful Fulani conquests of Zaria, Zanfara, Kano, Katsena, and Bauchi, Bornu was overrun. Shortly after this a sheikh, from the country extending eastwards from Lake Tchad, believing himself to be inspired to liberate the country, raised a small army, drove out the Fulani forces, and founded the present dynasty of Bornu. Some years later he attempted to expel the Fulanis from the Bauchi Province, but failed, and was compelled to come to terms.

The Haussas as well as the Bornuese are chiefly Mohammedans, but it is only among the higher ranks of the other tribes that a semblance of that religion has been adopted.

The tribes which had migrated from the East brought with them the agricultural knowledge of the Eastern nations. Among the noticeable evidences of this may be mentioned the “shaduf,” or dipping beam, used for irrigation in Egypt, which is similarly employed near Kano and Zaria. The absence of ploughs and the non-employment of cattle are, however, difficult to account for, as excellent cattle are common and thrive well in the most populous parts of the country. Tillage of the soil is still done entirely by hand, and, in those parts where the shallowest form exists, manure is extensively used. Among the many crops grown which are common to Oriental countries, as well as Northern Nigeria, are Guinea corn, maize, cotton, groundnuts, millet, benniseed, artichokes, wheat, and rice.

Agriculture shows the greatest development in the Province of Kano, where the population is dense, especially in the vicinity of the town from which the Province takes its name. The concentration of a large population in this locality was doubtless occasioned by the protection thus obtained against local enemies; and, as the realisation of the necessity for this becomes less each year, so will the inhabitants spread out into the richer lands towards the south. At a radius of thirty miles from Kano, it may be said that every available acre of ground is cultivated. It may also be said that nearly all the cultivation is continuous, and has been so for a long period, the renovation of the soil being secured each year by manuring. The mode of cultivation in these localities is for the most part shallow, and in many places the crops grown subsist entirely upon the manure applied. The Director of Agriculture, in the Bulletin of the Imperial Institute, vol. xi. (1913), p. 626, refers to the lack of fertility in the soil and to the common practice of cropping without a fallow for a number of years in succession. He also mentions, among other matters of interest, the recent expansion in cultivation of cowpeas and groundnuts; these being respectively third and fourth in order of importance among the cultivated crops.

Implements.—An illustration is given showing the method of using the three important agricultural implements employed by the Haussa cultivator (Fig. 27). The first of these is locally termed “Fatainya,” and is a curved-handled hoe with a blade of variable width. It is used for all operations of cultivation with the exception of turning up broad ridges and drilling. The implement shown in the centre is termed “Garma,” and is a broad, spade-like hoe, composed of an iron W-shaped frame, with several strips of iron riveted on the face, filling the interval between the arms. In the Zaria Province the iron strips are generally omitted, and the implement is called “Owya.” It is used for throwing up large spadefuls of soil in the preparation of the broad ridges which are made for nearly all kinds of crops. The last implement is the “Sangumi,” which is a thin rod with a small blade placed near one end and at right angles to it; its use is entirely for making drills for sowing seed.

All the fields for growing ordinary food crops, with the exception of cassava, rice, and sugar-cane, are prepared in ridge formation; the latter appearing to average about 8 in. high from the original surface. The furrows from which the loose soil has been removed increase the apparent height by the extent of their depth, and give the appearance of a good form of tillage having been practised. This is, however, seldom the case, as, except where irrigated crops are being treated, the ground is left untilled beneath the thrown-up soil. To compensate for the shallow state of the cultivation, manure is applied in large quantity, all animal refuse and ashes being carefully preserved, and often conveyed for long distances to the fields by men or donkeys.

The above conditions apparently apply only to the Haussa race, the pagan Gwaris and Bassas resorting to a much deeper form of cultivation and employing no manure. The Nupes and Yorubas do not know the use of manure for any crops except onions and tobacco, for both of which wood ashes are the chief substance applied.

The crops of the country may be roughly divided into rainfall, irrigated, and swamp kinds. The first are sown at the commencement of the wet season, and are greatly affected by the distribution of the rain, but include the most important sources of food. These are Guinea corn, millet, maize, groundnuts, cassava, sweet potatoes, etc. An inadequate or irregular rainy season often causes famine conditions. The irrigated crops are yams, Colocasia, onions, tobacco, peppers, rama-fibre, and wheat, the last being almost confined to the country north of the 11th degree. Cassava and sugar-cane are also frequently irrigated in the drier districts to the north. Irrigation is performed in the northern localities by means of the shaduf. The swamp crops are rice, Colocasia, and sugar-cane. The first is grown upon a flat-dug surface, the second upon high ridges made of swamp mud, and the third on low ridges bordering the rice fields. The villages north of Kano are often entirely built of the stalks of Guinea corn, and Fig. 31 represents a principal hut within such a structure. The fencing of the fields in this locality is generally made of the same material, but in the vicinity of Kano itself, Euphorbia or thorn hedges are more common.

Near Rogo, fences and hedges are usually dispensed with, paths forming the boundaries between fields.

The following table of value of exports shows the progress in the last five years before amalgamation with the Southern Provinces. The subsequent years are given at the end of this chapter.

RUBBER.—The extent of the export of this commodity from the Northern Provinces was less generally recognised than that from the coast countries, for the reason that the Northern Nigeria’s exports are necessarily shipped from Southern Nigerian ports, and have been included in the statistical figures of that country.

Until 1907 no separate statement was furnished indicating the quantity of rubber actually originating from the Northern Provinces; the whole produce leaving the country by the Southern Nigerian ports made it difficult to ascertain this. The following imperfect records show, however, that the production was of significant extent:

1905. The value of the rubber exported by two of the leading firms in the Northern Provinces was estimated at £101,207.
1906. The amount exported in the second half-year was given as 556,701 lbs., valued at £34,344. The year’s exports were said to be 574 tons. Estimating the whole at the same proportionate value as that given for the second half-year we have:
1906. 1,283,520 lbs. £79,185
1907. 1,187,588 lbs. £91,074

The decrease in recent years is accounted for by the fall which occurred in the price of rubber, but is probably partly due to the extermination of the vines by the wasteful process of preparing root rubber.

Sources.—The following are the trees and plants which have been used for extracting rubber:—

1. Funtumia elastica.—This is only found in a wild state in Southern Kabba and Bassa Provinces, and is recognised under the Yoruba name of “Ire.” Small pieces of fairly well-prepared rubber from this tree are occasionally brought in to Lokoja for sale.

2. Landolphia sp. (probably owariensis).—A clean “red nigger” rubber is sold, and is probably obtained from this species. It is generally of good quality, but not plentiful. It appears to be collected as a scrap rubber, and is made up in small irregular balls.

3. Landolphia sp.—“Root rubber,” termed locally “Attifufu,” and called by the trade “Brown cluster” or “Brown medium.” It is probable that several species of vines are used for this, which is not necessarily prepared from the root alone, the whole stem being pounded up. This seems to represent the commonest form of Northern Nigerian rubber, the preparation of which was at one time prohibited.

4. Landolphia florida or Thompsonii (?).—“Paste rubber,” called locally “Ebo,” is prepared from the latex of these vines by boiling with the admixture of “wood oil,” or the resinous exudation of Daniellia thurifera, until it reaches the consistency of bird-lime, when it is only capable of being handled in water, in which state it is sold to the merchants, who accumulate it in casks for shipment. It is inferior in quality, and only capable of export for cheap manufactures.

5. Carpodinus hirsutus.—“Flake rubber,” called “Aribedda,” is said to be the product of this vine, which grows commonly in Bassa. It is without resiliency and somewhat resembles the exudations of some of the species of Ficus.

6. Ficus platyphylla.—“Red Kano rubber,” or “Ballata,” known to the Nupe people as “Ogbagba.” This is prepared by boiling, without the addition of any foreign matter, and attains the consistency of a hardened paste, similar to the “guttas” made from the latex of the Shea-butter tree (Butyrospermum Parkii). It is distinguished in the Kano Province by the name “Danko Gawi,” shea gutta being known as “Danko Kadainya.”

7. Ficus trachyphylla.—This tree is called in Ilorin by the Yoruba name “Oapottoa,” and yields a latex which is discoloured pink by the sap of the tree with which it becomes mixed in tapping. When boiled and allowed to cool, the product is a reddish hardened substance, somewhat resembling guttapercha in appearance.

8. Ficus Vogelii.—Scrap rubber from this tree is said to be collected. In appearance this rubber is often good, but the shreds break up easily.

It will be seen from the above, that several of the so-called rubbers are unlike the valuable kinds in appearance and composition, and as such are, perhaps, incapable of being used in a pure state and for the most important manufactures for which rubber is employed. All kinds, however, seem to be marketable at a price which is remunerative to the exporter, so that the trade has become an extensive one.

Plantations.—It has been urged that Para rubber (Hevea brasiliensis) might be grown upon a large scale in the moist and well-watered areas, and Ceara (Manihot Glaziovii) and Funtumia elastica in the drier districts; but the country is not generally favourably adapted for growing the first and last mentioned. Ceara rubber seems to thrive well in climates similar to that of this country, and the rubber made from it is of the finest quality, but in many tropical countries it has shown great uncertainty in yield of latex, and often unaccountable cessation of flow. This has caused it to be less favourably regarded for plantation work. (Cf. Bull. Imp. Inst., 1913, 1916.)

Many parts of the country are suitable for Ceara cultivation, thriving as it does in localities susceptible to long periods of drought. In the German African Colonies the method of treating the tree seems advantageous, in view of the uncertainty of the yield after maturity is reached. In these places the plants are put out in extensive plots each year, and, after they have reached full growth, all the latex possible of extraction is taken out of them, and the exhausted trees are cut out, permitting the area to become renovated by the self-sown seedlings, which spring up in great profusion. Thus, each year a plot becomes completely renovated, without great expense being incurred. If Ceara planting should be adopted in Northern Nigeria, some such system as this might prove remunerative.

In the Lokoja forest reserve, about a hundred acres of Funtumia elastica were planted in 1906, but these have not succeeded as well as was originally expected, owing, probably, to want of moisture. A few Ceara and even Hevea plants, have been grown at Zungeru and Baro, but, as yet, no plantations have been made.

SHEA NUTS.—The shea nut is the seed or kernel contained in the green fruit borne by Butyrospermum Parkii, called locally “Kadainya.” The fruit, which ripens about May, is of variable size, from that of a pigeon’s egg to as large as a hen’s egg where only one nut is contained, but is nearly twice the size where two nuts are present in the same fruit. The fleshy rind is not more than one-sixth of an inch in thickness, is sweet to the taste, and contains a white latex, which coagulates into a product called “gutta-shea.” The natives in some places seem to regard the fruit as a delicacy, and the roads and paths, in districts where the tree is plentiful, are strewn with the nuts which have been thrown away after the fruit portions have been eaten. The nut is quite smooth, and is readily separated from the fleshy part.

The butter, which is extracted by the natives, is appreciated less than palm oil or groundnut oil for cooking, but is used as a substitute. In Europe the kernels as well as the extracted “butter” are employed, especially on the Continent, for the manufacture of vegetable butter and in candle factories.

In some places the fruits are collected and put in heaps, until the fleshy parts have decomposed and left the nuts clean, after which the kernels are extracted, dried in earthen stoves, and pounded or ground into a fine flour. This is then pounded again, with the addition of a little water, previous to being mixed in hot water to separate the fat. The latter rises to the surface and solidifies on cooling, being melted again for clarification by skimming previous to being poured into moulds made from plantain leaves or maize-cob sheaths. In this form it is sold for export, and is then known as “shea-butter.” An illustration is given (Fig. 28) of some Shea nut collectors resting beneath a Shea tree in the Ilorin Province.

Fig. 30, p. 162.

According to results obtained at the Imperial Institute (Bulletin of the Imperial Institute, 1908, p. 370; 1912, p. 290), the kernels contain from 40 to 50 per cent. of fat, as well as a small quantity of unsaponifiable matter resembling gutta-shea.

Where the nuts are very plentiful, and transport appears to be easy, the collection is often neglected, and the reason given is that there is some difficulty in removing the fruit from the nut, which makes the occupation unremunerative. But it is noticeable that the fleshy part quickly decomposes, and the clean nuts are frequently seen beneath the trees themselves, although in this situation the advent of heavy rain will often induce germination, and so spoil the kernel. This difficulty is obviated if the fruits are collected and placed under cover, being allowed to decompose without too much moisture.

Throughout the Ilorin and Nupe Provinces the nuts are at present collected for sale to the factories, but in size those grown in the Zaria Province are larger, and are now quite accessible. In this latter locality the double fruit, above referred to, appears to be common. In the tract of country through which the Baro-Kano railway now proceeds, after crossing the Kogin-Serikin-Pawa river, as far Zaria, localities containing very large and prolific trees are frequently met with, but the population is scanty, and collection is scarcely made for export purposes. Trees growing in cultivated areas are generally recognised as the property of the cultivator, forest trees only being common property. Women are the chief collectors of the nuts in the districts whence the supplies at present come, and their inability to penetrate far into the forests has sometimes been urged as a reason for larger quantities not being brought in to the factories. Now that the railway is present, it is probable that regular collectors will commence to exploit the forests for some distance on each side of the line, and that people from the more populous districts will be induced to visit them for the same purpose.

No record is available to show the amount of nuts and butter exported previous to 1905, but it must have been considerable, as the High Commissioner in his annual report for 1905-6 says: “The Shea nut export trade, which formerly constituted the staple of Northern Nigeria, continues to decrease in an unaccountable way, and is now an almost negligible amount.” Various reasons are given to account for a partial or gradual decrease, the most important of which is, that the people who used to rely on the collection of sylvan produce for a livelihood, have found a more lucrative employment in growing foodstuffs for the troops and Government staff, or in working upon the Government roads and railways. But, in spite of this, the value of Shea nuts and butter exported in 1907-8 reached a high figure, and placed these products second in order of value among those exported during the year. The export of Shea nuts in the two years following showed a further increase, being 3,922 and 9,085 tons for 1908 and 1909 respectively. There is a growing demand for Shea butter in Europe, and the supply is at present inadequate.

PALM OIL AND KERNELS.—The oil palm (Elæis guineensis) is almost absent from a large part of the country, and is rarely seen north of Zungeru, being chiefly confined to the vicinity of the rivers and the forests on the boundaries of Southern Nigeria.

An insignificant amount of palm oil is exported, as the local demand absorbs practically all that is produced, the kernels remaining being alone exported.

Only one variety is recognised in the country, and is that with a thin pericarp and thick-shelled kernel. It is similar to the form termed “Abe-pa” in the Gold Coast. Among the Haussa-speaking races the palm is called “Quaqua,” and in the Nupe language “Yi-ku-niche.”

Extraction of the oil for local use is generally done by boiling the fresh fruits, and a limpid product is obtained.

GROUNDNUTS.—The groundnut (Arachis hypogea), called “Geda” by the Haussas, is seen in two forms in Northern Nigeria, dependent, probably, on differences in soil and climate in the localities in which they are grown.

The form seen commonly in the vicinity of Bida, from which most of the exported nuts are procured, has a light-brown shell, and is similar to the ordinary Gambian kind. The soil in which this is grown is red, and, to some extent, this colour is imparted to the shell. The nuts growing in the northern districts near Kano, where the soil is sandy and light, resemble the kind which is considered the finest in the French Colonies, and is largely cultivated in Senegal. In this the shell is pale straw-coloured. Large exports have been made from Kano since railway facilities were provided.

Groundnuts are chiefly employed as a terminal crop in the cultivation adopted by the Nupes and Yorubas, but in the Kano and Zaria Provinces, where land is retained for long periods in cultivation and renovated annually by manure, they are often the first crop grown on opening new land, and are seldom planted later.

From an interesting article contributed by Mr. Lamb, the Director of Agriculture (Imperial Institute Bulletin, vol. xi. [1913]), entitled “Agriculture in Haussaland,” it appears that leguminous crops have recently been introduced more generally in the rotation employed among the Haussa cultivators. The author remarks that the cowpea (Vigna catjang) is now almost invariably grown with cereals, and that there is such an increase in groundnut cultivation that this has come into great prominence as an exported crop. This condition has been brought about entirely by the establishment of railway transport—a result which was foretold in the first edition of this work.

All the nuts exported at the present time are in a decorticated form, and the reason given for decortication is that there is a large saving in weight in carriage thereby. It is, nevertheless, generally admitted that in an undecorticated form the nuts are better preserved in transit, and it often happens that the price for undecorticated nuts is higher than for decorticated. It is, however, recognised that if the appearance of the shell is rusty or dirty, it should be removed before shipment, as this condition adversely affects the market value. The demand for undecorticated nuts is for confectionery, and is relatively small as compared with the amount used, chiefly in France, for the expression of oil. The weights of groundnuts exported in 1917 and 1918 were respectively 50,334 and 57,555 tons.

The Kano nuts appear to be of such a clean type that it might be found more advantageous to ship them in an undecorticated state, but this can be ascertained when transport has been facilitated sufficiently to establish a continuous trade with a particular market.

The chief markets for the product were Marseilles and Hamburg, where it was employed for the expression of oil, used principally for admixture with, or as a substitute for, olive oil. Although formerly almost entirely sent to the German port, they now come mostly to England. (Cf. Bull. Imp. Inst., vol. xvi. [1918].)

GUMS.—In the drier regions Acacia trees of several species become plentiful, but many of these do not seem to produce gum.

Some of the gum in the Sudan is said to be derived from A. arabica, Willd., which is not uncommon in certain localities, but is almost entirely unproductive in this country.

The tree known in Haussa as “Gawo,” identified as A. Albida, Delile, is perhaps the commonest species near Kano, and one which produces a small amount of reddish gum. None, however, is apparently collected from the tree in the district.

The species from which most of the gum is collected in Bornu is said to be identical with that called “Karu” in Kano, of which only immature specimens have as yet been examined. This is probably referable to A. Verek, Guill. & Perr., which is the most important source of the Senegal product, and to which Bentham refers A. Senegal, Willd.

In Kontagora a good quality of gum is obtained from a tree which has been identified as A. Caffra, Willd. This tree does not appear to occur plentifully here, but further investigation is necessary with regard to it in the dry uninhabited regions where it is found. An illustration of this tree is given (Fig. 29).

Another species which has been recorded by Barter from the Niger, and is said by him to yield “a gum like gum-arabic,” is A. mellifera, Bentham, and may be one of those from which the present exported product is collected.

On examination of the trade specimens, it is noticeable that the quality is inferior to most of the Sudan and Senegal kinds, owing, mainly, to the want of cleaning or sorting previous to sale. It has been suggested that an improvement in the quality might be effected by sorting the gum into different grades, cleaning it, and spreading it in the sun to bleach. The quantity of gum exported in 1908 is given as 789,949 lbs., and that for 1909 as 894,287 lbs.

Investigations carried out recently at the Imperial Institute show that Nigerian gum is little, if at all, inferior to Sudan gum, except that its mucilage is not quite so strong. Gums of the better class are mainly employed in confectionery, and for this purpose the cleaner, lighter-coloured gums of Northern Nigeria are quite suitable. (Bulletin of the Imperial Institute, 1908, pp. 29-60; 1910, pp. 352-65; and 1914, pp. 27-31.)

COTTON.—Three distinct forms of cotton are found in cultivation in the Northern Provinces. The best of these is that grown by the natives of the Bassa and Nassarawa Provinces, and possesses lint of rather long staple and a good colour, covering a clean seed. The seed-cotton from these Provinces is brought into Lokoja for sale. This variety seems well suited to the localities mentioned, but, although it has been tried in other parts of the country, it does not seem to thrive so successfully. In making a comparison of the lint for Liverpool market requirements, the standard employed is “Moderately Rough Peruvian,” which is a grade of higher price than “Middling American,” with which most of the West African cottons are compared.

In Ilorin, a woolly-seeded tall cotton plant is commonly cultivated, and, although yielding a fair quality of lint, it is not equal to that mentioned above. A small proportion of the cotton grown in the Ilorin Province finds its way to the Ogudu Ginnery of the British Cotton Growing Association, on the Niger, but the main crop is carried to various points on the Lagos Government Railway, and is sold for delivery to the Southern Nigerian ginneries of the Association. Small quantities of cotton belonging to this same variety are grown in Nupe, Kabba, and Kontagora, but the low ground of the Niger valley does not appear to be very suitable for cotton-growing.

In Zaria, Kano, and Sokoto Provinces, where the climate is drier, excellent conditions exist for the production of large supplies of cotton, but the population requires to become more distributed into the districts remote from the towns. In the above-mentioned Provinces, cotton has existed from the earliest times, and was long established as an important export to North Africa by caravan. A small-bolled variety with a short stem takes the place of the tall cottons of the Niger valley. The quality of the lint, although fair, is of a shorter staple, and the plant is less prolific.

In addition to the three kinds referred to, all of which are grown as field crops, single plants of a fourth are sometimes seen near villages, especially in the Bassa Province. This is the crimson-flowered tree-cotton identified as Gossypium arboreum, var. sanguineum, and is nowhere cultivated upon a large scale. The lint is silky and fine, and the seed is covered with green fuzz.

Exotic Cottons.—American and Egyptian seed have been introduced in many localities, especially in the Provinces of the Niger valley. Cotton grown from American Upland seed in Bassa Province has been well reported upon, but the deterioration of the quality of seed reproduced by this kind has proved a serious drawback to establishment. It is generally acknowledged that the indigenous cottons are hardier and more prolific than the introduced varieties, and are better able to withstand the attacks of the local insect pests. It is probable that the climate of the Northern Provinces will be found more suitable for the cultivation of American Upland cottons, as the indigenous plant of that region more nearly approximates the latter type.

Valuation of Cottons.—The following table shows the value of different cottons grown in Northern Nigeria and examined at the Imperial Institute. (See Professor Dunstan’s “British Cotton Cultivation,” pp. 34-37.)
