The Revolution came, and thenceforward there existed no legal impediments to the establishment of home markets by aid of which the farmer might be enabled to lessen the cost of transporting his produce to market, and his manure from market, thus giving to his land some of those advantages of situation which elsewhere add so largely to its value. The prohibitory laws had, however, had the effect of preventing the gradual growth of the mechanic arts, and Virginia had no towns of any note, while to the same circumstances was due the fact that England was prepared to put down all attempts at competition with her in the manufacture of cloth, or of iron. The territory of the former embraced forty millions of acres, and her widely scattered population amounted to little more than 600,000. At the North, some descriptions of manufacture had grown slowly up, and the mechanics were much more numerous, and towns had gradually grown to be very small cities; the consequence of which was that the farmer there, backed by the artisan, always his ally, was more able to protect himself against the trader, who represented the foreign manufacturer. Everywhere, however, the growth of manufactures was slow, and everywhere, consequently, the farmer was seen exhausting his land in growing wheat, tobacco, and other commodities, to be sent to distant markets, from which no manure could be returned. With the exhaustion of the land its owners became, of course, impoverished, and there arose a necessity for the removal of the people who cultivated it, to new lands, to be in turn exhausted. In the North, the labourer thus circumstanced, _removed himself_. In the South, he had _to be removed_. Sometimes the planter abandoned his land and travelled forth with all his people, but more frequently he found himself compelled to part with some of his slaves to others; and thus has the domestic slave trade grown by aid of the exhaustive process to which the land and its owner have been subjected. The reader may obtain some idea of the extent of the exhaustion that has taken place, by a perusal of the following extracts from an address to the Agricultural Society of Albemarle County, Virginia, by one of the best authorities of the State, the Hon. Andrew Stevenson, late Speaker of the House of Representatives, and Minister to England. Looking to what is the "real situation" of things, the speaker asks--
