But considering this statement only as a general proof of a great increase of the African trade, (without attempting to assign the proportion of increase) let us take another view of the same subject.
The Gold Coast is about 250 miles in extent, little more than a twentieth
part of the whole coast extending from Cape Blanco to Cape Negro.
Previously to the Abolition of the slave trade, the imports into Great
Britain from this space of coast used to consist of
about 20 tons of ivory valued at —- £7500
and about 1000 ounces of gold dust —- 4000
—- £11500
Since the Abolition of the slave trade the imports from this tract of coast have greatly increased; and it may be stated upon the undoubted authority of intelligent persons, perfectly acquainted with the facts, that the importations have amounted, during the last five or six years, to the annual value of from £120,000. to £180,000. The annual import of gold alone is stated to be about 30,000 ounces.
Thus it appears that the importation from the Gold Coast alone, (a space of 250 miles) into Great Britain since the Abolition of the slave trade, has been double the amount of the importation from the whole slave coast of Africa (an extent of 4500 miles) prior to that event.
A farther example may be taken from the colony of Sierra Leone, where a custom house was first established in May 1812; from whence accounts have been furnished of the imports and exports into and from that colony during the two years ending in May 1814.—The amount of the imports during that period, on which duties were actually paid, was £105,080. 15_s_. 3_d_. being the alleged prime cost of the goods, even without the cost of packages. In order to obtain the invoice price of the goods, one third at least must be added to the prime cost for necessary charges. The amount will then be about £140,000., or, on an average, £70,000. annually.
The exports from Sierra Leone during the same period have amounted to £91,539. 17_s_. 6_d_. being on an average £45,000. annually. The remainder of imports may be accounted for by the bills of exchange drawn upon this country for the expenses of the civil establishment and commissariat. Hence it appears that from the single river of Sierra Leone the imports into Great Britain were nearly, and the exports to the same river fully, equal to the imports and exports (exclusive of the slave trade) of the whole extent of the Western Coast of Africa prior to the Abolition.
The facts here stated relative to the extent of our innocent and legitimate commerce with the western coast of Africa, must be considered as highly interesting and important; both as shewing how extremely small that commerce was prior to the Abolition of the slave trade, and how much it has increased during the very few years which have since elapsed. This increase has certainly been much more considerable than there was any good reason for expecting, under the actual circumstances of the case.
If we were told of a country, whose staple article of export trade consisted of its own inhabitants, its men, women and children, who were procured (as must necessarily happen in the case of large and continued exports) by treachery and violence—where the whole population was either living in continual apprehension of captivity and eternal banishment from their native soil, or employed contriving the means of inflicting those evils upon others—we should at once conclude that the very insecurity of person and property, which such a state of society implied, would of itself extinguish all the motives to regular industry, and limit the culture of the soil very nearly to what was required for supplying the immediate wants of nature.
Such in fact were the circumstances of Africa prior to the year 1808; at which time the slave trade carried on by Great Britain, and the United States of North America having been abolished by those respective governments, and the slave trade of France and Holland being virtually abolished by the war, a considerable mitigation of the prevailing evils took place. A farther improvement was effected about three years afterwards, by means of the article in the treaty of amity with Portugal, which bound Portuguese subjects to confine their trading in slaves to places in Africa actually under the possession of that Government. By this arrangement the whole coast of Africa from Cape Blanco to the eastern extremity of the Gold Coast (with the exception of the Portuguese settlement of Bissao) were in a considerable degree liberated from the operation of the slave trade.
