The State authorities of New York subsef]uently employed him to examine and report on the boundaries of that state on the lines of New Jersey, Massachusetts and Connecticut ; and the vestry of Trinity Church, New York, invited him to become the historian of that ancient and noted parish. Mr. Daw.son did nothing under either of these requests, but his selection indicates the estiuuition in which he is held as an authority on historical questions relating to New York.

Mr. Dawson has long conducted an extensive correspondence with literary people and conspicuous actors in public events. He has been elected a resident member of the New York Historical Society, the American Institute, and the American Geographical and Statistical Society; an honorary member by the IMinnesota and the New England Methodist Historical Socifcties, and a corresponding member by the Massachusetts, Vermont, Pennsylvania, Delaware, Maryland, Virginia, Wisconsin, Chicago, and New England Historic- Genealogical, the Long Island, the Oneida and the Cayuga County Historical Societies; and also by the Worcester (JMassachusetts) Society of Antiquity, the American Statistical Association and the Albany Institute.

^Ir. Dawson pos.sesses a tine library on American history -- the result of many years of historical inquiry, and undoubtedly one of the most valuable collections, for practical purposes, in the country. Not only on the special subjects of which he has written, but in the general field of American history, Mr. Dawson's searching and retentive inti^llect Inis stored up a mass of most valuable information, in the use of which he is skilled by long practice to such an extent as to niake him one of the most formidable of controversialists.
