The Rhode Island Colonial Records are edited by J.R. Bartlett, 7 vols., 1856-62. One of the best state histories ever written is that of S.G. Arnold, History of the State of Rhode Island and Providence Plantations, 2 vols., New York, 1859-60. Many valuable documents are reprinted in the Rhode Island Historical Society’s Collections. The History of New England, with particular reference to the denomination called Baptists, by Rev. Isaac Backus, 3 vols., 1777-96, has much that is valuable relating to Rhode Island. The series of Rhode Island Historical Tracts, issued since 1878 by Mr. S.S. Rider, is of great merit. Biographies of Roger Williams have been written by J.D. Knowles, 1834; by William Gammell, 1845; and by Romeo Elton, 1852. Williams’s works have been republished by the Narragansett Club in 6 vols., 1866. The first volume contains the valuable Key to the Indian Languages of America, edited by Dr. Trumbull. Williams’s views of religious liberty are set forth in his Bloudy Tenent of Persecution, London, 1644; to which John Cotton replied in The Bloudy Tenent washed and made White in the Blood of the Lamb, London, 1647; Williams’s rejoinder was entitled The Bloudy Tenent made yet more Bloudy through Mr. Cotton’s attempt to Wash it White, London, 1652. The controversy was conducted on both sides with a candour and courtesy rare in that age. The titles of Williams’s other principal works, George Fox digged out of his Burrowes, Boston, 1676; Hireling Ministry none of Christ’s, London, 1652; and Christenings make not Christians, 1643; sufficiently indicate their character. The last-named tract was discovered in the British Museum by Dr. Dexter and edited by him in Rider’s Tracts, No. xiv., 1881. The treatment of Roger Williams by the government of Massachusetts is thoroughly discussed in Dexter’s As to Roger Williams, Boston, 1876. See also G.E. Ellis on “The Treatment of Intruders and Dissentients by the Founders of Massachusetts,” in Lowell Lectures, Boston, 1869.
