The same trade-returns show that the imports of African produce from the West Coast into Great Britain have been as follows. The "official value" is given before 1856, after that date the "computed real value" is given. Official value, 1851-55 . . . L4,154,725; average, L830,945 Computed real value, 1856-60 . . 9,376,251; " 1,875,250 " " " 1861-63 . . 5,284,611; " 1,761,537 The value of African produce has decreased during the last few years in consequence of the discovery of the petroleum or rock-oil in America. In 1864 between four and five thousand bales of cotton were shipped to England. It is to be borne in mind, that under the system which existed when Sierra Leone, the Gambia, and Gold Coast settlements were maintained for the promotion of the slave-trade, the lawful commerce was only L20,000 annually, and that now the amount of tonnage employed in carrying legal merchandise is greater than was ever engaged in carrying slaves.[105] W. Winwood Reade visited Sierra Leone during the Rebellion in America; but, being somewhat prejudiced against the Negro, we do not expect any thing remarkably friendly. But we quote from him the view he took of the people he met there:-- "The inhabitants of the colony may be divided into four classes:-- "First, The street-venders, who cry cassada-cakes, palm-oil, pepper, pieces of beef, under such names, as _agedee_, _aballa_, _akalaray_, and which are therefore as unintelligible as the street-cries of London. This is the costermonger type. "Second, The small market-people, who live in frame houses, sell nails, fish-hooks, tape, thread, ribbons, etc., and who work at handicrafts in a small way. "Third, The shopkeepers, who inhabit frame houses on stone foundations, and within which one may see a sprinkling of mahogany, a small library of religious books, and an almost English atmosphere of comfort. "Lastly, The liberated Africans of the highest grade, who occupy two-story stone houses enclosed all around by spacious piazzas, the rooms furnished with gaudy richness; and the whole their own property, being built from the proceeds of their ... thrift."
