It was Argall, too, who, while on a trading expedition on the Potomac, captured Pocahontas and brought her prisoner to Jamestown in an attempt to deal with her father, Powhatan. She was well received at Jamestown, where earlier she had often visited, and when her father refused to pay the price asked for her ransom, she was detained. Later, she preferred life with the English and did not wish to return to her native village. She was placed under the tutelage of Reverend Alexander Whitaker who instructed her in the Christian faith. Eventually she was baptized, and, in April 1614, in the church at Jamestown, married John Rolfe. This was a reflection of the religious concern that existed in Virginia. One of the ministers, Alexander Whitaker reported: That: "Sir Thomas Dale (with whom I am) is a man of great knowledge in divinity, and of a good conscience in all his doings: both which bee rare in a martiall man. Every Sabbath day wee preach in the forenoone, and chatechize in the afternoone. Every Saturday at night I exercise in Sir Thomas Dales house. Our Church affaires bee consulted on by the minister, and foure of the most religious men. Once every moneth wee have a communion, and once a yeer a solemn fast." TOBACCO It was John Rolfe who pioneered in the cultivation of the plant that was to be Virginia's economic salvation, tobacco. In the first years of the settlement every effort had been made to find products in the New World that would assure financial success for the settlers and the Company. Pitch, tar, timber, sassafras, cedar, and other natural products were sent in the returning ships. Attempts to produce glass on a paying scale proved futile, as did early efforts to make silk, using the native mulberry trees growing in abundance. The glass furnaces fell into disuse, and rats ate the silkworms. Even the native tobacco plant (_Nicotiana rustica_), found growing wild, was, as William Strachey reported, "... not of the best kind ... [but was] poore and weake, and of a biting tast ..." and initially held little promise. It was about 1610-11 that seed was imported into Virginia from the island of Trinidad very probably at the hand of John Rolfe, an ardent smoker, who was credited by Ralph Hamor as the pioneer English colonist in regularly growing tobacco for export. Hence he can be called the father of the American tobacco industry. In its initial stage, too, there was encouragement from the experienced Captain George Yeardley. Following the process of selection and crossing which had proved so successful for the Spanish cultivators in the West Indies, the initial efforts were rewarding. The new plant (_Nicotiana tabacum_) proved easily naturalized and adaptable to the Virginia soil.
