Answer:
Rolfe's successful tobacco experiments.
Step-by-step explanation:
Rolfe's successful tobacco experiments invigorated others to begin planting available land in Jamestown and in the settlements along the James River. Extensive planting began first at West and Shirley Hundreds and moved east to Point Comfort along a 140-mile stretch of the river. In 1622, despite the Indian uprising that abolished about 350 colonists and destroyed several plantations, the settlers' crop admitted 60,000 pounds. Later in the 1620s, the English took over-discharged Indian land and spread tobacco cultivation even farther by using the headright system, in which planters paid to transport people across the Atlantic in exchange for fifty acres of land. The Accomac peninsula was put under advancement by 1629 when a total of 2,000 acres of tobacco was being grown there.
