The documentary material of Maryland is very extensive, as the State has been fortunate in preserving most of its colonial records. _The Archives of Maryland_ (23 vols., 1889-1903), published by the Maryland Historical Society, is composed of the proceedings of the council, legislature, and provincial court. The _Fund Publications_ of the society (36 nos. in 4 vols., 1867-1900), are also valuable in this respect, and contain among other things _The Calvert Papers_ (_Fund Publications_, No. 34). A complete list of all these publications can be found in the annual report of the society for 1902. For the controversy between Lord Baltimore and the Puritans the chief authorities are Winthrop, _History of New England_ (2 vols., 1790-1853); _Lord Baltimore's Case Concerning the Province of Maryland_ (1653); _Virginia and Maryland, or Lord Baltimore's Case Uncased and Answered_ (Force, _Tracts_, II., No. ix.); Leonard Strong, _Babylon's Fall in Maryland, a Fair Warning to Lord Baltimore_; John Langford, _A Just and Clere Reputation of Babylon's Fall_ (1655); John Hammond, _Leah and Rachel_ (Force, Tracts, III., No. xiv.); _Hammond versus Heamans, or an Answer to an Audacious Prophet;_ Heamans, _Brief Narrative of the Late Bloody Designs Against the Protestants._ The battle of the Severn is described in the letters of Luke Barber and Mrs. Stone, published in Bozman, _Maryland_, II., 688. PLYMOUTH AND MASSACHUSETTS The standard authorities for the history of these two colonies are Thomas Hutchinson, _History of the Colony of Massachusetts Bay_ (3 vols., 1795-1828); John G. Palfrey, _History of New England_ (3 vols., 1858-1890); J.S. Barry, _History of Massachusetts_ (3 vols., 1855-1857). Very lively and interesting are Charles Francis Adams, _Massachusetts: Its Historians and Its History_ (1893); _Three Episodes of the History of Massachusetts_ (2 vols., 1895). The best account of Plymouth is J.E. Goodwin, _The Pilgrim Republic_ (1888).
