Early American Agriculture some plants mistakenly considered native to America may have been preserved by the Indians or may have grown wild until "discovered" in later years. A variety of the common agricultural crops of Europe were planted during the founding of the American colonies. Guinea corn, a sorghum plant grown on plantations in the South prior to the Civil War, was called "guine Corn" in the West Indies in 1601. It flourished in the summer of 1671 along with cotton and indigo on the Ashley River in South Carolina. The common use of Guinea corn in Africa, and as a food on slave ships, makes it seem probable that it was brought in with slaves at an early date. During their first two years at Jamestown, the colonists tried planting European crops. The plants did not mature because they were started too late in the season, and by 1609 most of the colonists were concentrating on Indian methods of agriculture. William Strachey, in writing of his travels through Virginia from 1610 to 1612, stated that the natural Virginia tobacco was inferior to varieties brought in from the West Indies. (3) Carrier attri- buted the importation of the improved tobacco seeds to Sir Walter Raleigh who brought them from Trinidad via England in 1595. John Rolfe first cultivated tobacco in Virginia in 1612. Silk production began its long, unavailing struggle for a place in American agriculture in 1621, when England encouraged mul- berry planting in Virginia in order to feed the silkworm. Five years later, the Dutch West India Company was sending samples of wheat, rye, barley, oats, buckwheat, beans, and flax back to the West India Company in Holland. Three hundred trees were shipped to Massachusetts Bay in 1630 to promote orcharding there.4 Hemp was among the first plants, and was used along with flax for sails and cordage for shipping. But there was no surplus for export. Further efforts were made in 1658 to promote silk production, and in 1661 the cultivation of flax and hemp was stimulated as part of the colonial mercantilistic policy of encour- 'In Massachusetts the Endicott expedition for the Massachusetts Bay Colony in 1628 was directed to take with it seeds of wheat, rye, barley, oats, beans, peas, stones of peaches, plums, cherries, and seeds of filberts, pears, apples, quince, and pome- granate, woad seed, saffron heads, licorice seed, madder roots, potatoes, hop roots, hempseed, flaxseed, and currant plants. By 1630 such vegetables as cabbage, turnips, lettuce, spinach, radishes, onions, peas, and beans had been introduced into the gardens of Massachusetts.
