_Pontigo_--a name applied to a river in that country where he found them--seems derived from Pont y Go, "The Smith's Bridge," or Pant y Go, "The Smith's Valley;" a smith dwelling beside a river or bridge being sufficient to originate such a name. Dr. Robertson says, in his "History of America," vol. ii. p. 126, that "the Indians were very ignorant of the use of metals; artificers in metals were scarce, and on that account a name might be given to a bridge or valley where one dwelt." Doeg Indians might be a corruption of Madog's Indians. The majority of those who have had any convictions on this subject have believed that Madoc first landed with his colony somewhere in New England, and that they then moved down the coast and inhabited portions of the country between Virginia and Florida. New England has some vestiges of European civilization which were there before the Pilgrim Fathers landed. The celebrated round tower at Newport, Rhode Island, about the origin of which tradition and history are silent, is certainly constructed on the same principle as Stonehenge, England, and many other Cambrian memorials. It conforms exactly to the Druidic circle. Its materials are unhewn stone. It rests upon eight round columns, twenty-three feet in diameter, and twenty-four feet in height. Any person familiar with Cambrian and Scandinavian archæology will not hesitate to attribute the construction of this tower rather to the Cambrian than to the Scandinavian navigators. A letter written by Charles Lloyd, Esq., of Dôl y Frân, in Montgomeryshire, already mentioned, published in 1777 by Rev. N. Owen, jun., A.M., in a pamphlet entitled "British Remains," strongly confirms Mr. Jones's narrative, and the truth of Madoc's voyages. Mr. Lloyd says that he had been informed by a friend that a Mr. Stedman, of Breconshire, about thirty years before the date of his letter, was on the coast of America in a Dutch bottom, and being about to land for refreshment the natives kept them off by force, till at last this Stedman told his fellow Dutch seamen that he understood what the natives spoke. The Dutch bade him speak to them, and they were thereupon very courteous; they supplied them with the best things they had, and told Stedman that they came from a country called Gwynedd (North Wales), in Prydain Fawr (Great Britain). Prydain was the son of Hugh the Mighty, and supposed to have been the first to establish government and set up royalty in the isle of Britain, and the island was called by his name. Mr. Lloyd said that Mr. Stedman found these Welsh Indians along the coast between Virginia and Florida. Furthermore, this gentleman said that a Mr. Oliver Humphreys, a merchant, who died not long before the date of Mr. Lloyd's letter, told him that when he lived at Surinam he spoke with an English privateer, or pirate, who, being near Florida, careening his vessel, had learned, as he thought, the Indian language, which his friend said was perfect Welsh.
