A day or two after the departure of the colonists a ship sent by Raleigh arrived, and about fourteen or fifteen days later came three ships under Sir Richard Grenville, Raleigh's admiral. Grenville spent some time beating up and down Pamlico Sound, hunting for the colony, and finally returned to England, leaving fifteen men behind at Roanoke to retain possession.[12] This was the second settlement. The colonists who returned in Drake's ships brought back to Raleigh two vegetable products which he speedily popularized. One was the potato,[13] which Raleigh planted on his estate in Ireland, and the other was tobacco, called by the natives "uppowoc," which he taught the courtiers to smoke. Most of the settlers who went with Lane were mere gold-hunters, but there were two who would have been valuable to any society--the mathematician Thomas Hariot, who surveyed the country and wrote an account of the settlement; and John White, who made more than seventy beautiful water-colors representing the dress of the Indians and their manner of living. When the engraver De Bry came to England in 1587 he made the acquaintance of Hakluyt, who introduced him to John White, and the result was that De Bry was induced to turn Hariot's account of Virginia into the first part of his celebrated _Peregrinations_, illustrating it from the surveys of Hariot and the paintings of John White.[14] If Raleigh was disappointed with his first attempt at colonization he was encouraged by the good report of Virginia given by Lane and Hariot, and in less than another year he had a third fleet ready to sail. He meant to make this expedition more of a colony than Lane's settlement at Roanoke, and selected as governor the painter John White, who could appreciate the natural productions of the country. And among the one hundred and fifty settlers who sailed from Plymouth May 8, 1587, were some twenty-five women and children. The instructions of Raleigh required them to proceed to Chesapeake Bay, of which the Indians had given Lane an account on his previous voyage, only stopping at Roanoke for the fifteen men that Grenville had left there; but when they reached Roanoke Simon Ferdinando, the pilot, refused to carry them any farther, and White established his colony at the old seating-place. None of Grenville's men could be found, and it was afterwards learned that they had been suddenly attacked by the Indians, who killed one man and so frightened the rest as to cause them to take to sea in a row-boat, which was never heard of again.
