America's Crop Heritage aging crops thought to be of value to the empire. By 1679 the Dutch had introduced clover; and orchards planted to apples, peaches, pears, and cherries were thriving. There is also some evidence of the introduction of clover about 1615. CEREALS AND GRASSES Many accounts of the introduction of rice varieties in South Carolina are questionable, but the proprietors of South Carolina wrote in 1677 that they were trying to get rice seed for distribu- tion. Rice was first planted in the area about 1688, and during the next decade the rice industry was encouraged by the appear- ance of new, superior varieties. These introductions, probably from many parts of the world, led to an era of experimentation in the eighteenth century. (3) The rise of the rice industry, like that of the cultivation of tobacco in Virginia, marked the beginning of a successful colony in South Carolina. During the eighteenth century rice became an exportable commodity much in demand in England. Later, John Bradby Blake brought the upland rice from Canton to Charleston in 1772. Rice culture was inaugurated in Louisiana by the "Company of the West" in 1718. Many pasture and forage crops were introduced during the colonial period. Bent grass, had become a wild pasture grass by the middle of the seventeenth century. Millet, a rather com- mon crop of Old World origin, was probably brought in at a very early date. Pearl millet is thought to be a native of Africa, and was brought to America by slaves. It was noticed growing in Jamaica on Negro plantations in 1689 and was later grown by slaves in the South. The common millet was grown in Massa- chusetts in 1637, and a hundred years later, planters were fatten- ing poultry on it. Cowpeas are mentioned by the earliest writers on American products. They were grown in New England before 1663, in South Carolina before 1682, and were found in North Carolina about 1700. Sloane, the English botanist, noted the black-eye pea in 1707 and called it the "Calavance." Alfalfa was un- doubtedly brought in by Columbus in 1493. Its early history, which is confused with that of lucerne and bur clover, is im- possible to unravel. It was grown in Georgia in 1735 and four years later was found growing in South Carolina. Red clover was
