It was not until 1717 that any effort was made to improve the lands between the Savannah and the Altamaha. In that year Sir Robert Montgomery, Bart., whose father was joined with Lord Cardross in his measures for establishing a Scots colony in Port Royal, published _A Discourse Concerning the Designed Establishment of a new Colony to the South of Carolina_, in what he termed "the most delightful country in the universe." This pamphlet was accompanied by a beautiful but fanciful plan representing the form of settling the districts or county divisions in his province, which he styled "the Margraviate of Azilia." In his description of the country he writes "that Nature has not blessed the world with any tract which can be preferable to it; that Paradise, with all her virgin beauties, may be modestly supposed, at most, but equal to its native excellencies." Having obtained, from the Lords Proprietors of Carolina a grant of the lands between Savannah and the Altamaha, he issued his proposals for settling this "future Eden"; but, though garnished with the most glowing descriptions, and set forth under the most captivating attractions, they were issued in vain; and the three years having expired within which he was to make the settlement or forfeit the land, the territory reverted to Carolina, and his scheme of colonization came to an end. The Margraviate of Azilia was magnificent upon the map, but was impracticable in reality. The Lords Proprietors of Carolina having failed in their scheme of government, and their authority being crushed by the provincial revolution of 1719, they sold their titles and interest in that province to Parliament in 1729; reserving to Lord John Carteret, one of their number, the remaining eight shares of the country, as he refused to join the others in disposing of the colony. After the purchase of the territory of Carolina, which then extended from the St. John's to Albemarle Sound, it was deemed too large for one government, and was therefore divided into two provinces, under the respective titles of North and South Carolina. The territorial boundary of South Carolina, however, on the south, was the Savannah River; the remaining portion being then held in reserve by the British Crown.
