guage; the proceedings of the Common Council of New York City, the reports of the Comptrollers of this city, and the papers and official acts of the United States Senate and of the State Legislature at Albany. I have not given my authorities, as I cannot suppose that they are accessible to any of my readers, but the correctness of the statements is susceptible of verification, and may be implicitly relied upon.
I gratefully acknowledge the important services rendered me by Mr. Bernard Casserly, the efficient General Agent of the Commissioners of Emigration, who is familiar with all the minutiae of the service, and the history of the Board for which he has labored ever since its creation with intelligence and zeal. I am also under special obligations to Mr. Andrew Carrigan and Mr. Thurlow Weed for the very interesting information contained in Chapter V. Mr. Weed, although confined to his chamber by illness, assisted me with his valuable advice, and gave me important information concerning the origin of the Commission.
I am likewise indebted to my friends, Mr. Henry Villard, of Boston, the able Secretary of the American Social Science Association, and Mr. Thomas Burke, of this city, for the revision of my manuscript; to Mr. Charles Goepp for the greater part of Chapter IX., and to several officers of the Commissioners of Emigration, among whom I would name Mr. George W. Wheeler, Col. L. Cantador, Mr. A. H. Hicks, and Dr. A. Reimer, for the readiness with which they have supplied me with copies of important tables and other necessary documents.
