It must be noted also that of the tobacco sent to England itself, a part was reshipped to foreign countries. In 1610 a law was enacted for the refunding of all import duties upon articles that were re-exported. This drawback applied also to colonial products, but under Charles I an exception was made in their case and the privilege withdrawn. In consequence the importers made a vigorous protest in Parliament, and the King, in 1631, modified his policy by ordering that of the nine pence duty then in operation, six pence should be refunded when the tobacco was shipped abroad. In 1632 the drawback was increased to seven pence leaving the total duty paid by the merchants who traded through England to foreign countries two pence a pound only.[4-38] Although this constituted a most serious obstacle to trade and at times aroused the merchants to bitter protest, it by no means completely blocked re-exportation. So great were the natural qualifications of Virginia for producing tobacco, that it was possible to purchase a cargo from the planters on the James, proceed with it to London, pay there the two pence a pound duty, reship it to the continent and sell it there at a profit.[4-39] Although this trade was not extensive, it must have had an important influence in maintaining prices and in bringing prosperity to all classes in the colony. Thus Virginia, contrary to the wishes of the mother country and in defiance of her regulations, enjoyed for its staple product in the years prior to 1660, a world market. Whether by direct trade or by re-exportation from England a goodly share of the annual crop was consumed in foreign countries, a share which had it been left in England to clog the market, would have reacted disastrously upon all concerned. It is apparent, then, that in the first half century of its existence Virginia was the land of opportunity. The poor man who came to her shores, whether under terms of indenture or as a freeman, found it quite possible to establish himself as a person of some property and consideration. We may imagine the case of the servant who had completed his term and secured his freedom at any time during the third decade of the Seventeenth century. As we have seen, it was an easy matter for him to secure a small patch of land and the tools with which to cultivate it. By his unassisted efforts, if he applied himself steadily to the task, he could produce a good crop of tobacco, consisting perhaps of some 400 pounds. This he could sell to the merchants for from two shillings to six pence a pound, or a total of from £10 to £40.[4-40]
