What proportion of land in Virginia already taken up is now cultivated as near as you can judge?
There is in Virginia, at a moderate computation, about 500,000 acres granted by patents, of which not above 40,000 acres are cultivated and improved; besides many thousand acres of waste land high up in the country.
Why have not the prosecutions, neglected in Colonel Nicholson's time, been continued since?
Colonel Nicholson was the first Governor of Virginia who directed prosecutions for arrears of quit-rents, beginning with Colonel Laurence Smith. The case was ready for trial but the Governor came to England, and the case was afterwards compounded for a small matter.
Have any parcels of land been seized for the King's use, for want of planting or failure to pay quit-rents?

Are negro servants included in the persons who, if imported, make "rights" to grant of land. [?]
Negro servants give a right to land to those who import them, who thereupon take up land, contrary to the true intention of seating the country; but the practice being general, to the advantage of certain persons, no notice is taken of it.
Have you ever known of false certificates of rights, and how have the parties guilty thereof been punished?
