[Sidenote: Mr. John Laird and Sir William Fairbairn.] As the success of these vessels was gradually determining the problem of the suitableness of iron to ship-building purposes, and was drawing attention to the subject, Messrs. Fawcett and Preston established at Liverpool a building yard in connection with their engine factory under the direction of Mr. Page, and constructed several small vessels entirely of iron.[113] Mr. Laird, of Birkenhead, proceeding upon a larger scale, prosecuted this branch of naval architecture with uninterrupted prosperity.[114] Mr. Fairbairn, afterwards Sir William Fairbairn, also took part, at an early period, in cultivating the new art; and ranks with those to whose influence and skill it was first indebted for public confidence. Removing from Glasgow, where he had commenced business, he established himself at Millwall, on the Isle of Dogs, and there became one of the principal constructors of iron vessels upon the Thames. His efforts proving successful, other eminent engineers pursued the same branch of art with the like results; among them may be mentioned Messrs. Miller and Ravenhill, whose vessels were considered at the time to be of exquisite workmanship and beauty of form; and Messrs. Ditchburn and Mare, who built a considerable number of iron vessels, including the _Fairy_, the tender to the Queen’s yacht, her form and speed gaining them a high reputation. [Sidenote: The _Elburkah_, 1832, and _Garry Owen_, 1834.] In 1832, Messrs. Laird were bold enough to carry into practice the theory of iron vessels for ocean navigation; and in the course of that year the firm of MacGregor, Laird, and Company built the _Elburkah_, of 55 tons, as consort to the _Quorra_ in her expedition up the Niger.[115] These enlightened firms justly considered that, whatever objections might be urged against vessels built of iron, they would at least possess equal sea-going qualities and, in some branches of trade, peculiar advantages. Combining strength and lightness of draught, the _Elburkah_ would be better adapted than any vessel built of wood for the exploration and navigation of African rivers:[116] nor were they deceived in their calculations. Immediately afterwards Messrs. Laird of Birkenhead commenced the construction of another iron vessel, the _Lady Lansdowne_ for the navigation of Lough Derg, River Shannon. In 1834 they built the _Garry Owen_, destined to run between Limerick and Kilrush. This vessel (125 feet long and 21 feet 6 inches wide, propelled by two engines of 45 horse-power each) was unfortunately, or perhaps, under the circumstances, fortunately for the progress of science, driven on shore with various other vessels during a strong gale on her first voyage; she, however, sustained comparatively little injury, while nearly all the others, which were built of wood, were totally wrecked or seriously damaged: this important fact, as a practical answer to one of the most reasonable objections raised
