Meanwhile, the new Law of Abolition had not a retroactive effect.  No more new slaves were made, but the old ones had not yet recovered their liberty.

It was under those circumstances that England set an example.  In May, 1833, a general declaration emancipated all the blacks in the colonies of Great Britain, and in August, 1838, six hundred and seventy thousand slaves were declared free.

Ten years later, in 1848, the Republic emancipated the slaves of the French colonies, say about two hundred and sixty thousand blacks.  In 1861, the war which broke out between the Federals and Confederates, of the United States, finishing the work of emancipation, extended it to all North America.

The three great powers had then accomplished this work of humanity.  At the present hour, the trade is no longer carried on, except for the benefit of the Spanish and Portuguese colonies, and to satisfy the wants of the populations of the Orient, Turks, or Arabs.  Brazil, if she has not yet restored her old slaves to liberty, at least no longer receives new ones, and the children of the blacks are born free there.

It is in the interior of Africa, in the prosecution of those bloody wars, waged by the African chiefs among themselves for this man-hunt, that entire tribes are reduced to slavery.  Two opposite directions are then given to the caravans:  one to the west, toward the Portuguese colony of Angola; the other to the east, on the Mozambique.  Of these unfortunate beings, of whom only a small portion arrive at their destination, some are exported, it may be to Cuba, it may be to Madagascar; others to the Arab or Turkish provinces of Asia, to Mecca, or to Muscat.  The English and French cruisers can only prevent this traffic to a small extent, as it is so difficult to obtain an effective surveillance over such far-extended coasts.

But the figures of these odious exportations, are they still considerable?

Yes!  The number of slaves who arrive at the coast is estimated at not less than eighty thousand; and this number, it appears, only represents the tenth of natives massacred.

After these dreadful butcheries the devastated fields are deserted, the burnt villages are without inhabitants, the rivers carry down dead bodies, deer occupy the country.  Livingstone, the day after one of these men-hunts, no longer recognized the provinces he had visited a few months before.  All the other travelers—­Grant, Speke, Burton, Cameron, and Stanley—­do not speak otherwise of this wooded plateau of Central Africa, the principal theater of the wars between the chiefs.  In the region of the great lakes, over all that vast country which feeds the market of Zanzibar, in Bornou and Fezzan, farther south, on the banks of the Nyassa and the Zambesi, farther west, in the districts of the upper Zaire, which the daring Stanley has just crossed, is seen the same spectacle—­ruins, massacres, depopulation.  Then will slavery in Africa only end with the disappearance of the black race; and will it be with this race as it is with the Australian race, or the race in New Holland?
