  The principle advocated is that of making the vessel large enough to carry her own coal for the voyage, just as the ‘Great Western’ steam-ship did in 1838 (p. 292)—The size being limited only by the extent of demand for freight, and by the circumstances of the ports to be frequented (p. 292). 31.

Report on the Tenders for the Ship and Engines (May 18, 1853) 301   A short specification was drawn up for the engines, and detailed drawings and specifications for the ship (p. 301)—Tenders have been received for the engines from Mr. J. Scott Russell, Messrs. Watt and Co., and Mr. Humphrys (p. 302)—After frequent communications with these gentlemen, Messrs.

Letter to the Secretary of the Eastern Steam Navigation Company, on Position as Engineer of the Company (August 16, 1854) 311   His unusual stake in the undertaking, and the heavy responsibility he has incurred (p. 311)—The work is one which requires that it should be entirely under his individual management and control (p. 312)—And therefore there must be no other adviser or source of information on any question connected with the construction or mode of carrying out the work (p. 312). 40. Letter to the same on an Article in a Newspaper (November 16, 1854) 313   His general rule is not to notice newspaper articles, but this one bears the stamp of authority (p. 313)—Marked care is shown in depreciating his former efforts in advancing steam navigation, and in representing him, in the present case, as the passive approver of the project of another (p. 313)—Whereas it originated solely with him, and has been worked out by him with great thought and labour (p. 314). 41.
