The London of 1700 experienced a boom in slave stocks as the London of 1900 in rubber stocks. Merchants and captains, after a few years' absence, returned to London to buy houses, carriages and gold plate, and by their political largesses to win the title of baronet, and even seats in the House of Lords. This illusion of gold finally fell upon the throne itself, and King William and Queen Mary lent the traffic royal patronage. At the very time when men in Boston, exultant over the success of their experiment in democracy, were writing home to London about this ideal republic of God that had been set up at Plymouth, and the orb of liberty began to flame with light and hope for New England, this other orb began to fling out its rays of sorrow, disease and death across Africa and the southern sands. At length, in 1713, Queen Anne, in the Treaty of Utrecht, after a long and arduous series of diplomatic negotiations, secured for the English throne a monopoly of the slave traffic, and the writers of the time spoke of this treaty as an event that would make the queen's name to be eulogized as long as time should last. But two hundred years have reversed the judgment of the civilized world. History now recalls Queen Anne's monopoly of the slave traffic as it recalls the Black Death in England, the era of smallpox in Scotland,--for one such treaty is probably equal to two bubonic plagues, or three epidemics of cholera and yellow fever. Finally, an informal agreement was entered upon between the English slave dealers, the Spaniards and Portuguese,--an agreement that was literally a "covenant with death and a compact with hell." The Portuguese became the explorers of the interior, the advance agents of the traffic, who reported what tribes had the tallest, strongest men, and the most comely women. The Spaniards maintained the slave stations on the coast, and took over from the Portuguese the gangs of slaves who were chained together and driven down to the coast; the English slave dealers owned the ships, bought the slaves at wholesale, transported the wretches across the sea, and retailed the poor creatures to the planters of the various colonies. Between 1620 and 1770 three million slaves were driven in gangs down to the African seacoast, and transported to the colonies. At this time some of the greatest houses in London, Lisbon and Madrid were founded, and some of the greatest family names were established during these one hundred and fifty years when the slave traffic was most prosperous. De Bau thinks that another 250,000 slaves perished during the voyages across the sea. For the eighteenth century was a century of cruelty as well as gold,--of crime and art,--of murderous hate and increasing commerce. If the prophet Daniel had been describing the Spain, Portugal and England of that time, he would have portrayed them as an image of mud and gold,--but chiefly mud. Little wonder that Thomas Jefferson, in his "Notes on Virginia," treating of
