From this time forward both colonies developed into strong and flourishing plantations and with each succeeding year increased the cultivation of tobacco which had now become more extensively cultivated than all the other products combined. Its culture however was looked upon with the same disapproval by Charles II. who confirmed the old laws against its sale and cultivation. But notwithstanding the remonstrances of the Stuarts the plant grew in use and favor and could not be uprooted even by a kingly hand. The early cultivators of the plant received a fresh impetus from the importation of a new species of labor in the form of Negro slaves brought from the West India islands. They arrived in the Ship Treasurer "being manned by the best men of the colony who set out on roving in ye Spanish dominions in the West Indies" and after a successful cruise against the Spaniards returned with their spoils including a certain number of Negroes. Rolfe in alluding to the importation of Negroes says: "About the last of August came in, a Dutch man-of-warre that sold us twenty negars." Most writers are of the opinion that this was in 1620, one of whom says "in the same year that the Pilgrims landed at Plymouth, slaves landed in Virginia." Another writer says of the introduction of slave labor into the Plantations, "Is there not a probability that the vessel was under control of Argall, if not the ship Treasurer? If twenty negroes came in 1619, as alleged, their increase was very slow, for according to a census of 16th of February, 1624, there were but twenty-two then in the colony, distributed as follows: eleven at Flourdiew Hundred, three at James City, one at James Island, one at the plantation opposite James City, four at Warisquoyok, and two at Elizabeth City."
