Every care, also, has been observed to give credit to other writers for the assistance derived from their books, and in this connection I would specially mention the “Encyclopædia Britannica,” Mr. Cecil Torr’s “Ancient Ships,” Sir W. Laird Clowes’ “History of the British Navy,” Mr. H. W. Wilson’s “Ironclads in Action,” “The Warships of Europe” by Chief Engineer J. W. King, U.S.A., “The New American Navy” by John D. Long, ex-Secretary of the Navy, U.S.A., “Maori Art” by A. Hamilton, “The New Zealanders” by George F. Angas, “History of Steam Navigation” by John Kennedy, “The Story of the Submarine” by Colonel C. Field, “Ancient and Modern Ships” by Sir George C. V. Holmes, “Submarines and Submersibles” by E. C. Given, M.Inst.C.E., “Canoes of the Solomon Islands” by C. M. Woodford, F.R.G.S., “Naval Architecture” by J. Fincham, “Rise and Progress of the Royal Navy” by Chas. Derrick, “Transactions of the Institution of Naval Architects,” Appleton’s Cyclopædia of American Biography, “History of the Marine Architecture of All Nations” by J. Charnock, “Our Ironclad Ships” by Sir E. J. Reed, “Cyclopedia of Antiquities” by Rev. F. D. Fosbroke, M.A., and the “Naval,” “Navy League,” and “Fleet” Annuals. A great deal of information has also been derived from the columns of _Engineering_, the _Engineer_, the _Times_, _Illustrated London News_, _Marine Engineer_, _Scientific American_, and other papers, to all of which I express my deep indebtedness. If it should be found that I have not acknowledged every item derived from these sources, I trust that this general admission will cover my shortcomings in this respect.
