To British navigation the trade was vital. Each year scores of merchantmen crossed to the Chesapeake and swarmed in every river and creek, delivering their English goods to the planters and taking in return the hogsheads of tobacco. In 1690 the tobacco fleet numbered about 100 ships, aggregating 13,715 tons; in 1706 it counted no less than 300 sails.[7-21] Nor must it be forgotten that re-exported tobacco also added many a goodly merchantman to the navy and gave employment to many a seaman. Altogether Virginia and Maryland constituted an invaluable asset, an asset which ranked in importance secondly only to the sugar plantations. It would naturally be supposed that the fortunate turn of events which restored to the tobacco colonies their European market would have reacted favorably upon the small planters of Virginia, not only insuring plenty to those already established, but adding new recruits from the ranks of the indentured servants; that the process of making prosperous freemen from the poor immigrants who flocked to the colony, the process interrupted by the passage of the Navigation Acts, would have been resumed now that these laws no longer prevented the flow of tobacco into the continental countries. Such was not the case, however. A comparison of the lists of immigrants with the rent roll of 1704 shows that but an insignificant proportion of the newcomers succeeded in establishing themselves as landowners. In four lists examined for the year 1689, comprising 332 names, but seven persons can be positively identified upon the rent roll. In 1690, eight lists of 933 names, reveal but twenty-eight persons who were landowners in 1704. Of 274 immigrants listed in 1691, six only appear on the Roll. In 1695, seven lists comprising 711 names, show but ten who possessed farms nine years later. Of 74 headrights appearing in 1696, but two are listed on the roll; of 119 in 1697 only nine; of 169 in 1698 one only; of 454 in 1699, only seven; of 223 in 1700 but six.[7-22] All in all not more than five per cent. of the newcomers during this period prospered and became independent planters. Apparently, then, the restored prosperity of the colony was not shared by the poorer classes, the increased market for tobacco did not better materially the chances of the incoming flood of indentured servants.
