In 1724 Hugh Jones observed that the farther a person went northward from the York or southward from the James, the poorer the quality of the sweet-scented tobacco, "but this maybe (I believe) attributed in some Measure to the Seed and Management, as well as to the Land and Latitude." John Custis in a letter to Philip Perry in 1737 wrote that he grew Oronoco on the Eastern Shore of Virginia using the same seed as he did for his sweet-scented York crop. It appears that as the sandy loam necessary for the growing of sweet-scented tobacco became exhausted and the planters expanded into the heavy fertile soils, the tobacco became the strong, coarse Oronoco. As virgin soil became scarce, Oronoco was no longer confined to the richest soils, nor was it thought to be less sweet-scented than its rivals. Toward the end of the eighteenth century tobacco inspectors found it so difficult to distinguish the various types, that they classed all tobacco as Oronoco. Thus it seems quite possible that both Oronoco and sweet-scented were originally one variety which became two, primarily because of the different soil composition. TRANSPORTATION TO MARKET In the early days of the colony the small ocean-going merchant vessel was the only method of transportation essential to marketing the tobacco crop. Such a small ship was able to anchor at many of the plantation wharves and load its cargo of tobacco. Next to fertility, the proximity to navigable water was the most important factor in influencing the planter in the selection of a tract of land. However, later expansion of the tobacco industry into the interior and the increase in the size of all ocean-going ships made some mode of transportation within the colony a necessity. When the ships could not get directly up to the wharf or enter shallow creeks on which many of the plantations were located, small boats called flats or shallops were used to transport the hogsheads to the anchored vessels. In 1633 the General Assembly provided that all tobacco had to be brought to one of the five warehouses--to be erected in specified localities--to be stored until sold. The planters objected immediately and petitioned the House of Burgesses to allow ships to come into every county, "where they will find at every man's house a store convenient enough for theire ladinge, we beinge all seated by the Riverside." The planters also complained that they had "... noe other means to export but by Boatinge." Carrying the tobacco for long distances in the shallop involved a risk, as well as an additional expense. By rolling the hogsheads directly on board a ship anchored at his own wharf or only a few miles away the planter eliminated the danger involved in transporting his tobacco in an untrustworthy, heavily laden shallop, and he also saved the increase in freight charges for delivery to the ships by the seamen. Freight rates were the same from his wharf to England as they were from any other point in the colony.
