The third installment of \"Some North Carolina Tracts of the Eighteenth Century,\" by William K. Boyd. John Rutherfurd (1724-1782) was born in Scotland and migrated to North Carolina sometime prior to 1735, settling in Wilmington. He was twice elected town commissioner of Wilmington, appointed by Governor Johnston as a member of the Council and Receiver General of Quit Rents in 1751, and was appointed Lieutenant General of the expedition against the Regulators by Governor Tryon prior to 1768. He wrote \"The Importance of the Colonies to Great Britain, etc.,\" reproduced here in full, in 1761 while in England. The piece examines themes of traditional mercantilism such as the balance of trade between England and the colonies and the future of that balance.
