In 1619 a Dutch privateer put into the James river and disembarked twenty Africans who were sold to the settlers as slaves. This event, so full of evil portent for the future of Virginia, might well have afforded a natural and satisfactory solution of the labor problem. Slaves had long been used in the Spanish colonies, proving quite competent to do the work of tending the tobacco plants, and bringing handsome returns to their masters. But it was impossible at this time for England to supply her plantations with this type of labor. The slave trade was in the hands of the Dutch, who had fortified themselves on the African coast and jealously excluded other nations. Thus while the demand for negro slaves remained active in the colony, they increased in numbers very slowly. The muster of 1624-25 shows only 22.[2-18] During the following half century there was a small influx of negroes, but their numbers were still too small to affect seriously the economic life of the colony.[2-19] The settlers were thus forced to look to England itself to supply them with hands for their tobacco fields. They knew that in the mother country were many thousands of indigent persons who would welcome an opportunity to better their lot by migrating to the New World. And the English statesmen, feeling that there was need for blood letting, welcomed an opportunity to divert the surplus population to the new colony in America.[2-20] The decline in English foreign trade and the stagnation of home industry had brought unemployment and suffering to every class of workers. Wages were so low that the most industrious could not maintain themselves in comfort, while to provide against want in case of sickness or old age was hardly to be thought of. Every parish, every town swarmed with persons stricken with abject poverty. In some parts of the country no less than 30 per cent of the population were dependent in part upon charity for their daily bread, while many were driven into vagabondage and crime, becoming an element of danger rather than of strength to the nation.[2-21] It seemed to the planters that the mother country constituted an abundant reservoir of labor, a reservoir already overflowing and capable of supplying indefinitely their every need. The only drawback was the long and expensive voyage across the Atlantic. The fare, even for the poorest and most crowded accommodations, was no less than six pounds sterling, a sum far beyond the means of the thriftiest laborer.[2-22] Obviously some scheme had to be evolved to overcome this difficulty before Virginia could make use of English labor. And so the planters turned to the simple expedient of advancing the passage money to the immigrant and of placing him under strict legal bonds to work it out after reaching the colony.
