While no attempt will here be made to solve the matter, it has been felt that, in justice to the subject, these charges could not be ignored when presenting statistics which are derived mainly from the sources thus challenged. Indeed, in comparing for the present work the statistics given by various journals—even in journals confined to the same district—innumerable disparities have been met with, and the agreement has only been _en grosse_. Such being the case, it may be asked, could not other and more reliable sources be consulted? The obvious alternative of using the authoritative returns of the Board of Trade, or of Lloyd’s Register, at once suggests itself, but objections to this are even more serious than to using the press statistics. The returns issued annually by the Board of Trade only relate to “Merchant Shipping” registered as such, whereas it is well known that in the returns furnished by the shipbuilders all sorts of vessels built by them are included, and that a very considerable tonnage in war vessels and small vessels for military purposes, also in light-draught river craft, both for our own and other countries, is annually turned out from merchant shipyards. The same objections apply to Lloyd’s Register Summary, although, strangely enough, the figures there more nearly correspond with the builders’ than with the Board of Trade returns, the information given in both cases being the gross tonnage of merchant shipping built and registered in the United Kingdom. Everything considered, the statistics compiled from press returns more accurately represent the work accomplished throughout the districts than those afforded by any of the sources named. In the statistics which follow, therefore, the press returns have been adopted, but to simplify matters for purposes of comparison—the degree of unreliability warranting it—the terminal figures in large quantities have been reduced or increased to hundredths, according as they have chanced to be under or above fifty. The fluctuation from year to year in the shipbuilding industry of the principal districts over an extended period is exhibited in an interesting manner by the diagram facing page 188, consisting of curves set up on equidistant ordinates representing years, to the scale shown on the right of the diagram. The figures from which the curves have been constructed will be found to the left of the diagram.[32]
