sides (Governor William Berkeley and Chief Necotowance). The treaty set the boundary between Virginia and Indian lands at the lower Blackwater River (or Blackwater Swamp) up to its head at "Yapim" (modern Franklin), and thence in a directly straight line to the "Monacan town" (Mowhemencho, at the eastern tip of Powhatan County). Native Americans were only allowed to cross this line at the newly built Fort Henry on the Appomattox, where Petersburg now is, and they had to display a special badge, without which they could be killed on the spot, or after 1662, arrested. By the late 17th century, some settlers from Virginia were crossing the Blackwater-Ft. Henry-Monacan town boundary, and settling in territory of Indian tribes such as the Appomattoc and the Nottoway. The government of Virginia repeatedly ordered such people to return northeast of this line, and would not allow the land beyond to be surveyed for land grants. In 1685, the House of Burgesses asked Governor Howard for permission to grant some land south of the Blackwater River. The governor denied the request. According to a petition by the colonial government of Virginia made to the King, dated May 1, 1688, the Tributary Indians, who still legally owned the land west of the line, allegedly asked for settlers to move into their territory. The reason for the request was said to be fear of invasion by larger, non-Tributary tribes, in light of their own dwindling numbers, besides that "Such large Tracts of Land are of noe benefit nor use unto them". However, King William and Queen Mary wanted the moratorium on patents extended, and in 1691, another order was given demanding all settlers south of the river to return north. By 1706, the Blackwater boundary law was revoked and settlements south of the river or west of the line became legal. Transportation in early colonial Virginia was usually done by water. The many wide estuaries and wetlands made land transport difficult, especially when moving goods. Migration and settlement patterns thus tended to follow the rivers, most of which flowed from the west and emptied into Chesapeake Bay. The Blackwater River was an exception. It flowed south to Albemarle Sound. The Blackwater's headwaters were close to the main settlements along the James River (some within three miles). By the early 18th century, Virginians were living along the upper Blackwater River and using the river for travel and
