The proportion of Negroes in the North was small, falling from 3.4% in 1790 to 1.8% in 1910. Neverth eless, 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.’”23
In New York and New Jersey, Negroes formed between 7 and 8% of the total population in 1790, which meant that they were probably 25% of the labor force of those colonies, especially on the farms.
The growth of the great slave crops shows the increasing economic value of Negro labor. In 1619, 20,000 pounds of tobacco went from Virginia to England. Just before the Revolutionary War, 100 million pounds a year were being sent, and at the beginning of the twentieth century, 800 millions were raised in the United States alone. Sugar was a luxury for the rich and physicians until the eighteenth century, when it began to pour out of the West Indies. By the middle of the nineteenth century a million tons of cane sugar were raised each year and this had increased to nearly 3 million in 1900. The cotton crop rose correspondingly. England, the chief customer at first, consumed 13,000 bales in 1781, 572,000 in 1820, 871,000 in 1830 and 3,366,000 in 1860. The United States raised 6 million bales in 1880, and at the beginning of the twentieth century raised 11 million bales annually.
This tremendous increase in crops, which formed a large part of modern commerce, was due primarily to black labor. At first most of this labor was brute toil of the lowest sort. Our estimate of the value of this work and what it has done for America depends largely upon our estimate of the value of such toil. It must be confessed that, measured in wages and in public esteem, such work stands low in America and in the civilized world. On the other hand, the fact that it does stand so low constitutes one of the greatest problems of social advance. Hard manual labor, and much of it of a disagreeable sort, must for a long time lie at the basis of civilized life. We are continually transmitting some of it to ma chines, but the residuum remains large. In an ideal society it would be highly-paid work because of its unpleasantness and necessity; and even today, no matter what we may say of the individual worker or of the laboring class, we know that the foundation of America is built on the backs of the manual laborer.
This was particularly true in the earlier centuries. The problem of America in the fifteenth and sixteenth centuries was the problem of manual labor. It was settled by importing white bond servants from Europe and black servants from Africa, and compelling the American Indians to work. Indian slavery failed to play any great part because the comparatively small number of Indians in the West Indies were rapidly killed off by the unaccustomed toil, or [because they] mingled their blood and pooled their destinies with the Negroes. On the continent, on the other hand, the Indians were too powerful, both in numbers and organization, to be successfully enslaved. The white bond servants and the Negroes therefore became the main laboring force of the New World and with their toil the economic development of the continent began.
There arose a series of special laws to determine the status of laborers which became the basis of the great slave codes. As the free European white artisans poured in, these labor codes gradually came to distinguish between slavery based on race and free labor. The slave codes greatly weakened the family ties and largely destroyed the family as a center of government or of economic organization. They made the plantation the center of economic life and left more or less religious autonomy. They provided punishment by physical torture, death or sale, but they always left some minimum of incentive by which the slave could have the beginnings of private possession.
In this way, the economic organization was provided by which the middle classes of the world were supplied with a cheap sweetening material derived from sugar cane; a cheap luxury, tobacco; larger quantities of rice; and finally, and above all, a cheap and universal material for clothing, cotton. These were things that all men wanted who had anything to offer in labor or materials for the satisfaction of their wants. The cost of raising them was a labor cost almost entirely because land in America was at that time endless in fertility and extent. The old world trade, therefore, which sought luxuries in clothing, precious metal and stones, spices, etc., for the rich, transformed itself to a world-wide trade in necessities incomparably richer and bigger than its medieval predecessor because of its enormous basis of demand. Its first appearance was in the slave trade where the demand for the new American crops showed itself in a demand for the labor necessary to raise them; thus the slave trade itself was at the bottom of the rise of great commerce, and the beginning of modern international commerce. This trade stimulated invention and was stimulated by it. The wellbeing of European workers increased and their minds were stimulated. Economic and political revolution followed, to which America fell heir. New immigrants poured in. New conceptions of religion, government and work arose and at the bottom of it all, and one of its efficient causes, was the toil of the increasing millions of black slaves.
As the nation developed, this slave labor became confined more and more to the raising of cotton, although sugar continued to be the chief crop in the West Indies and Louisiana, and rice on the southeast coast and tobacco in Virginia. This world importance of cotton brought an economic crisis: Rich land in America, adapted to slave methods of culture, was becoming limited, and must either be increased or slavery would die an economic death. On the other hand, beside the plantation hands, there had grown up a large class of Negro servants and laborers who were distributed both north and south. These laborers in particular came into competition with the white laborer and especially the new immigrants. This and other economic causes led to riots in Philadelphia, New York and Cincinnati, and a growing conviction on the part of [the] newly enfranchised white workingmen that one great obstacle in America was slave labor, together with the necessarily low status of the Freedmen. These economic reasons overthrew slavery.24
After the legal disappearance of slavery, its natural results remained in the mass of Freedmen who had been trained in the necessary ignorance and inefficiency of slave labor. On such a foundation it was easy to build and emphasize race prejudice. On the other hand, however, there was still plenty of work for even the ignorant and careless working
