It is my intention to write a History of Merchant Shipping; I am not aware that there exists any work of the kind contemplated. No doubt everything relating to the vessels of ancient times has been published in one form or another, as also an account of all that is known of the maritime commerce of the Middle Ages; but this information is widely scattered, and frequently so diffused among other matters of a very different description, that considerable research is necessary to ascertain where it is to be found. I desire to remedy this inconvenience, and to furnish from those fragmentary materials a consecutive, though necessarily a condensed, account of the Merchant Shipping, Ancient and Modern, of those nations which at different periods have carried on an extensive over-sea commerce. I shall also presume to correct some errors and misapprehensions which have found their way into the writings of men who, though far more competent to undertake the work of an historian, have not had an opportunity of gaining a practical knowledge of this special subject. It is only from Holy Writ, from the fragments in the works of heathen historians and poets, and from the sculptured monuments of the East, that information can be obtained about the vessels and commerce of very ancient times. From such sources I shall endeavour to compile, in a manner as brief as possible consistently with perspicuity, a narrative of how these vessels were constructed, manned, and navigated, separating, as far as my knowledge and experience will permit, facts from fiction, and omitting legends frequently accepted as historical truths. It can serve no good purpose to record descriptions of ships evidently the creations of romance; and, in a work professing to deal with established facts, care must be taken to admit nothing improbable unless well authenticated. It will not be the least pleasing portion of my work to furnish, as fully as I can, a description of the manners and customs of the seamen of all nations, and, at the same time, to notice incidentally their habits, prejudices, and superstitions. To illustrate the effects produced upon maritime commerce by the laws of different nations, it will be necessary to direct attention to those legislative measures which have had a marked bearing upon its prosperity or otherwise. Towards the close of this work, the merchant vessels of our own time, the cost of construction, speed, and capacity for cargo, will be fully described, as well as the number and duties of the crew, and the expenses of management. I shall endeavour to supply every material fact connected with the business of the shipowner, which nowadays is separated from that of the merchant, so that hereafter a complaint may not be urged against me for having followed the example of other writers, and by so doing omitted interesting and instructive knowledge, simply because it was of a character hitherto considered beyond the province of the historian.
