Moreover the black slave brought into common labor certain new spiritual values not yet fully realized. As a tropical product with a sensuous receptivity to the beauty of the world he was not as easily reduced to be the mechanical draft-horse which the northern European laborer became. He was not easily brought to recognize any ethical sanctions in work as such but tended to work as the results pleased him and refused to work or sought to refuse when he did not find the spiritual returns adequate; thus he was easily accused of laziness and driven as a slave when in truth he brought to modern manual labor a renewed valuation of life.

The Negro worked as farm hand and peasant proprietor, as laborer, artisan and inventor and as servant in the house, and without him, America as we know it, would have been impossible.

The numerical growth of the Negro population in America indicates his economic importance. The exact number of slaves exported to America will never be known. Probably 25,000 Negroes a year arrived in America between 1698 and 1707. After 1713 this rose to 30,000 and by 1775 to over 40,000 a year. The American Revolution stopped the trade, but it was revived afterward and reached enormous proportions. One estimate is that a million Negroes came in the sixteenth century, three million in the seventeenth, seven million in the eighteenth and four million in the nineteenth or fifteen million in all. Certainly at least ten million came and this meant sixty million killed and stolen in Africa because of the methods of capture and the horror of the middle passage. This, with the Asiatic trade, cost black Africa a hundred million souls.[55] Bancroft places the total slave population of the continental colonies at 59,000 in 1714, 78,000 in 1727, and 293,000 in 1754.

In the West Indies the whole laboring population early became Negro or Negro with an infiltration of Indian and white blood. In the United States at the beginning of our independent national existence, Negroes formed a fifth of the population of the whole nation. The exact figures are:[56]

The proportion of Negroes in the North was small, falling from 3.4% in 1790 to 1.8% in 1910. Nevertheless even here the indirect influence of the Negro worker was large. The trading colonies, New England and New York, built up a lucrative commerce based largely on the results of his toil in the South and in the West Indies, and this commerce supported local agriculture and manufacture. I have said in my Suppression of the Slave Trade: “Vessels from Massachusetts, Rhode Island, Connecticut, and, to a less extent from New Hampshire, were early and largely engaged in the carrying slave-trade. ‘We know,’ said Thomas Pemberton in 1795, ‘that a large trade to Guinea was carried on for many years by the citizens of Massachusetts Colony, who were the proprietors of the vessels and their cargoes, out and home. Some of the slaves purchased in Guinea, and I suppose the greatest part of them, were sold in the West Indies.’ Dr. John Eliot asserted that ‘it made a considerable branch of our commerce.... It declined very little until the Revolution.’ Yet the trade of this colony was said not to equal that of Rhode Island. Newport was the mart for slaves offered for sale in the North, and a point of reshipment for all slaves. It was principally this trade that raised Newport to her commercial importance in the eighteenth century. Connecticut, too, was an important slave-trader, sending large numbers of horses and other commodities to the West Indies in exchange for slaves, and selling the slaves in other colonies.

“This trade formed a perfect circle. Owners of slavers carried slaves to South Carolina, and brought home naval stores for their ship-building; or to the West Indies and brought home molasses; or to other colonies, and brought home hogsheads. The molasses was made into the highly prized New England rum, and shipped in these hogsheads to Africa for more slaves. Thus the rum-distilling industry indicated to some extent the activity of New England in the slave-trade. In May, 1752, one Captain Freeman found so many slavers fitting out that, in spite of the large importations of molasses, he could get no rum for his vessel. In Newport alone twenty-two stills were at one time running continuously; and Massachusetts annually distilled 15,000 hogsheads of molasses into this ‘chief manufacture.’”[57]
