The task which Mr. Bolles had undertaken was chiefly in correction of certain erroneous statements which had been made in newspaper articles and printed sermons, issued in his locality, most of which statements had been derived from ecclesiastical authors, who had found it expedient to adopt various current representations and traditions which had appeared on the church side of the controversy rather than to enter upon any research in this matter. As will be seen, some portion of Mr. Bolle’s vindication had been published in a local paper. This is comprised in the first chapter. In compiling the History, careful search was made for every item of reliable information concerning John Rogers and the Rogerenes, and every fact that was discovered is set plainly before the reader, in chronological order. It would be quite possible for a reader to view the entire material that has been examined for the production of this History. The County Court records are at the county clerk’s office in Norwich. The records of the Superior Court are in the secretary’s office, in the State House, at Hartford. The records of the General Court have been published and are to be found in many public libraries. The Rogerene books still extant are very rare, so much so that they could only be seen as a whole by going here and there among the owners. The titles of these works will be found at the end of the Appendix, together with statement of where single copies may be found. Some of the material used for the History is from “Letters of Mr. Samuel Hubbard.” The portions of these letters quoted in this work may be seen in Benedict’s “History of the Baptists.” The “Journal of William Edmundson” and “The Life and Travels of Samuel Bownas” have furnished some important particulars. These two works are rare outside of Quaker libraries. Miss Caulkin’s “History of New London,” from which quotations will be found, is in many public libraries in New England and elsewhere. The scandalous work of Peter Pratt, “The Prey Taken from the Strong,” is in the Prince collection in the Boston Public Library and in the Massachusetts Historical Society’s Library in Boston. A copy of “The Reply of John Rogers 2nd” is in the Connecticut Historical Library at Hartford. The last half of the original manuscript of the Hempstead Diary is in the Historical Rooms at New London, while the first half is at the “Old Hempstead House,” at New London. This Diary has recently been published in book form by the New London Historical Society. “An Account of the Debate between Rev. Mather Byles and The Brethren” of the Congregational Church of New London may be seen in the New London Public Library. An interesting side-light was furnished by Mr. Julius F. Sachse, in his work entitled “The Ephrata Cloister,” Vol. II, Chapter IV.
