It appeared from Custom-house returns, officially laid before Parliament, that the average annual value of all imports from Africa into Great Britain for twenty years prior to 1787, fell short of £72,000; and even this small sum included the imports, not only from the whole Western coast of Africa between Cape Negro in latitude 16 deg South and the straits of Gibraltar, but also from some parts bordering on the Mediterranean. The average annual value of these imports, during the last five years of that period, viz. 1783, 4, 5, 6 and 7, appears, from the same official returns, to have been about £90,500. If from this amount be deducted the value of the articles appearing to have been imported from Morocco and other adjoining countries, there will be left somewhat less than £70,000 for the value of all our imports from the Western Coast of Africa; that is, from the country lying between Cape Blanco, latitude 21 deg north, and Cape Negro, latitude 16 deg south, being an extent of 4500 miles of coast. The average annual exports from Great Britain to the Western coast of Africa during the same period (exclusive of the exports connected with the Slave Trade) may be estimated at a sum not materially exceeding £50,000.
The compiler of the present statement possesses no documents or means of information, which enable him to shew what was the extent of the commerce of Great Britain with Africa (unconnected with the Slave Trade) during the period from 1788 to 1807, the year in which the Slave Trade was abolished; but there is good reason to believe that it had not materially increased within that time.
It might be impracticable at present, from the loss of the Custom-house books, to obtain any authentic account of exports and imports during the last seven years. But this defect of official information is in some degree supplied by an authentic statement, made out on a particular occasion by a Committee of the African Company, from accounts with which they were furnished from the Custom-house, through the intervention of Government. The object of the Company in obtaining these accounts was to procure authentic data relative to some public measure which was in agitation, connected with the African trade. The following statement was extracted from the books of the Company.
Imports from Africa into Great Britain.
1808. £374,306 1809. 383,926 1810. 535,577
[Sidenote: exclusive of gold dust, which is not subject to any custom-house entry]
Exports from Great Britain to Africa.
1808. £820,194 1809. 976,872 1810. 693,911
The great difference between the value of the exports and imports in this case was accounted for by an experienced officer of the African Company by supposing that a large proportion (from one third to a half) of the goods exported, was captured by the enemy. If this be the true explanation, the account must have been balanced by the exports of gold dust, and the bills of exchange drawn from the British settlements on the African coast. Another supposition (and perhaps a more probable one) is that a considerable part of the exports found their way into the hands of the contraband slave traders, and was employed in carrying on their illegal speculations.
But, even if we consider the imports alone, the increase in the commerce of Africa during the before mentioned period is altogether astonishing; so much so, as almost to induce a suspicion that there is some fallacy in the statement, although there does not appear to be any specific ground for questioning its correctness. For if to the amount of the imports as above stated, we add the value of the gold dust imported, we shall find that this additional commerce nearly fills up the chasm occasioned by the Abolition of the slave trade, extensively as that trade was carried on by this country.
