The "Rose method" of water transportation, the lashing of two canoes together, had practically disappeared on the upland waters by 1800, being replaced by a small open flat-bottomed boat called the bateau, which carried a load of from five to eight hogsheads. Two planters, N. C. Dawson and A. Rucker, both of Amherst County, patented a bateau, in the early 1800's, which was a great improvement over the earlier ones. This bateau was from forty-eight to fifty-four feet long, but very narrow in proportion to its length. It was claimed that with a crew of three men these new "James River Bateaux" could make the round trip from Lynchburg to Richmond in ten days. They floated down the stream with ease, but worked their way back upstream with poles. Shortly before the turn of the eighteenth century canals had been constructed around the falls from Westham to Richmond, and the upland boats were able to load and unload their cargoes at the wharves in Richmond. In 1810 it was estimated that about one-fourth of the entire Virginia tobacco crop came down the James River and through the Westham Canal into Richmond. There were land and water routes in the Roanoke Valley that led to Petersburg. Tobacco was taken all the way to Petersburg by wagon, or carried by boat from the upper Roanoke and its tributaries to the falls at Weldon, North Carolina, and from there to Petersburg by wagon. Owing to the tobacco trade coming down the Roanoke, Clarksville became a small market town. In the Farmville area many of the planters sent their tobacco down the Appomattox River to Petersburg, rather than overland by wagon. Soon after 1800 the Upper Canal Company built a canal that connected Petersburg with the navigable waters of the Appomattox River. Virginia's waterways served her transportation problem well until they were superseded by the railroads in the ante-bellum days. ORIGIN AND DEVELOPMENT OF THE INSPECTION SYSTEM Within a few years after Rolfe's successful experiment in the cultivation of tobacco, it became necessary to inaugurate some means of improving the quality of the Virginia tobacco. Once it was discovered that tobacco could be successfully and profitably grown in Virginia, everyone wanted to grow it. Blacksmiths, carpenters, shipwrights, and even the minister frequently grew a patch of tobacco. Owing to inexperience in farming of any kind, plus the fact that the commercial production of tobacco was new even to most of the experienced farmers, much of the tobacco produced was of a very low quality. For centuries many planters seem to have placed quantity above quality in growing tobacco. Anyone could grow tobacco in certain quantities, but only a few could produce tobacco of superior quality.
