Cultivation practices during the early years at Jamestown appear to have been a combination of those used by the Indians and those of the farmers in England; modifications and new techniques were developed as the settlers became experienced planters. The early Jamestown settlers followed the Indian custom of planting the tobacco seed in hills as they did corn, although some probably followed the practice as described by Stevens and Liebault's _Maison Rustique_ or _The Country Farm_, published in London in 1606: For to sow it, you must make a hole in the earth with your finger and that as deep as your finger is long, then you must cast into the same hole ten or twelve seeds of the said Nicotiana together, and fill up the hole again: for it is so small, as that if you should put in but four or five seeds the earth would choake it: and if the time be dry, you must water the place easily some five days after: And when the herb is grown out of the earth, inasmuch as every seed will have put up his sprout and stalk, and that the small thready roots are entangled the one within the other, you must with a great knife make a composs within the earth in the places about this plot where they grow and take up the earth and all together, and cast them into a bucket full of water, to the end that the earth may be separated, and the small and tender impes swim about the water; and so you shall sunder them one after another without breaking them. This was perhaps the forerunner of the tobacco plantbed, as it appears from the above description that a half dozen or so plants were taken from each hill sown and transplanted nearby. Just when the planters stopped planting tobacco like corn is not known. Thomas Glover's _Account of Virginia_, written in 1671, is perhaps the first written account which mentions sowing the seeds in beds. He wrote, "In the Twelve-daies [before Christmas?] they begin to sow their seed in the beds of fine Mould..." A somewhat more detailed account was written in 1688 by John Clayton, an English clergyman visiting in Virginia. He relates that before the seeds were sown the planters tested the seed by throwing a few into the fire; if they sparkled like gunpowder, they were declared to be good. The ground was chopped fine and the seeds, mixed with ashes, were sown around the middle of January. To protect the young plants, the seedbed was usually covered with oak leaves, though straw was used occasionally. Straw was thought to harbor and breed a fly that destroyed the young plants, and if straw was used, it was first smoked with brimstone to kill this fly. Oak boughs were then placed on top of the leaves or straw and left there until the frosts were gone, at which time they were removed so that the young tender plants were exposed to allow them to grow strong and large enough to be transplanted.
