Nevertheless the plantation drew upon the outside world for many articles, especially luxuries, and the owner had to find the wherewithal to make payment. The almost universal answer to this problem was--tobacco. It was not an ideal answer, and historians have scolded the departed planters vigorously for doing the sum in that way, yet the planters were victims of circumstances. They had no gold or silver mines from which to draw bullion that could be coined into cash; the fur trade was of little importance compared with that farther north; the Europe of that day raised sufficient meat and grain for its own use, and besides these articles were bulky and costly to transport. But Europe did have a strong craving for the weed and, almost of necessity, Virginians set themselves to satisfying it. They could hardly be expected to do otherwise when a pound of tobacco would often bring in England more than a bushel of wheat, while it cost only a sixtieth part as much to send it thither. It is estimated that prior to the Revolution Virginia often sent out annually as much as ninety-six thousand hogsheads of tobacco. Tobacco took the place of money, and debts, taxes and even ministers' salaries were paid in it. The disadvantages of tobacco culture are well known. Of all crops it is perhaps the most exhausting to the soil, nor was a large part of Virginia particularly fertile to begin with. Much land was speedily ruined, but nothing was so cheap and plentiful in that day as land, so the planter light-heartedly cleared more and let the old revert to the wilderness. Any one who travels through the long settled parts of Virginia to-day will see many such old fields upon which large forest trees are now growing and can find there, if he will search closely enough, signs of the old tobacco ridges. Only heroic measures and the expenditure of large sums for fertilizer could make such worn-out land again productive. Washington himself described the character of the agriculture in words that can not be improved upon: "A piece of land is cut down, and left under constant cultivation, first in tobacco, and then in Indian corn (two very exhausting plants), until it will yield scarcely anything; a second piece is cleared, and treated in the same manner; then a third and so on, until probably there is but little more to clear. When this happens, the owner finds himself reduced to the choice of one of three things--either to recover the land which he has ruined, to accomplish which, he has perhaps neither the skill, the industry, nor the means; or to retire beyond the mountains; or to substitute quantity for quality in order to raise something. The latter has been generally adopted, and, with the assistance of horses, he scratches over much ground, and seeds it, to very little purpose."
