In committing itself to this policy the royal Government felt that the plantations would play a useful and necessary part in the great system which was planned, and in so doing would find prosperity. It had been the hope of the English people that their colonies would produce the articles which were so badly needed by the mother country to revive her waning industry and permit a greater measure of economic independence. Although more than half a century had passed since the first foothold had been gained upon the American continent, this expectation was as far from realization as ever. The colonies, from Massachusetts to Barbados were producing, not the articles which England especially needed, but those for which they had the greatest natural aptitude, especially tobacco and sugar. And these staples they sent, not to England alone, but to various foreign countries as well. In short the vision of a closely knit, self-sustaining empire, the vision which had been in men's minds for many decades before the founding of Jamestown, seemed to have proved delusive. The colonies were developing interests and commercial connections hostile to those of the mother country, were nourishing the manufactures and shipping of foreign nations almost as much as those of England. And this the Government at London would not tolerate. The colonial trade with strangers must come to an end. If Virginia and Maryland produced more tobacco than the English market could absorb, they could find ready relief by turning their energies into other channels. Let them furnish the old country with pig iron or potash or silk or ship-stores and they would find ready and eager purchasers. So reasoned the English, and as their views were backed by the mandates of Crown and Parliament, the colonists were forced to submit. If they could fit themselves into the system prescribed for them, all would be well and good; if they found this impossible, they would have to suffer without hope of redress. And suffer Virginia did for a full quarter of a century. The tobacco of the Chesapeake bay colonies had long since reached the point where it required a world market. If confined to England alone, only a fraction of the output could be consumed and disaster was certain. It was well enough for the Government to restrict the importation of Spanish leaf and to prohibit the planting of tobacco in England, these regulations could do no more than give the colonists undisputed possession of the home market, and the home market was not enough. This point seems to have been ignored by those writers who have contended that the strict enforcement of the British colonial system in itself entailed no hardship upon the tobacco colonies.
