Dawson has written a pai)er on " The Sons of Liberty in New York ;" one on " The Battle of Harlem Heights," and one on "The City of New York on Sunday Morning, Ai)ril 23, 1775," all of them for the New York Historical Society ; one on the " Battle of Bennington " for the Vermont Historical Society ; and one on the " Battle of Long Island " for the Long Island Historical Society, together with several minor tracts, and numerous articles for periodicals with which be has had no editorial connection; and he edited, in ISOl, for the Mercantile Library Association of New York City a volume of original papers, generally of the Revolutionary War, to which he added voluminous notes. The introduction to the last-named volume, which bore the title of "New York City During the American Revolution," attracted much attention, since it contained a carefully

prepared and minute description of the city as it was at that early period, as if written at the time and by one who was personally acquainted with every part of it, and with the principal persons who lived there. Like the greater number of Mr. Dawson's works this volume was printed in elegant form for private circulation, and commands very high prices when copies are thrown on the market. In 1866 he edited the official " Record of the Trial of Joshua Hett Smith, Esq.,, for Alleged Complicity in the Trea,son of Benedict Arnold," of which only fifty copies were printed ; and five large octavo volumes of selections from the Uisiorical Magazine, bearing the general title of "The JIagazine Miscellany," and elegantly printed in an edition of only twenty-five copies, have also appeared under his editorial supervision.
