The fashion in ships changed very slowly. As we have seen, what may be called the ancient period of sailing ships closed about the time Jacques Cartier appeared in Canada. When the fore-and-aft-trimmed sails were invented in 1539, the modern age began. This has three distinctive eras of its own. The first lasted for about a century after the time of Jacques Cartier; and its chief work was to free itself of ancient and mediaeval limitations.
The second, or central, modern era lasted twice { 66} as long, from the middle of the seventeenth century to the middle of the nineteenth. It thus covered one century under the Fleurs-de-lis in Canada and another under the Union Jack. It also exactly corresponded with the long era of the famous British navigation laws, of which more will presently be heard. During this period sails were improved in size, cut, and setting. The changes can be described only in technical language. Jibs became universal, adding greatly to handiness in general and the power of tacking in particular. Four sails were used on a mast--main, top, topgallant, and royal. Naval architecture was greatly improved, especially by the French. But this improvement did not extend to giving the hull anything like its most suitable shape. The Vikings were still unbeaten in this respect. Even the best foreign three-deckers were rather lumbering craft.
The third era began with the introduction of the clippers about 1840, and will not end till deep-sea sailing craft cease to be a factor in the world's work altogether. It was in this present era, when steamers were gaining their now unquestioned victory, and not during previous eras, when steam was completely unknown, that sailing craft reached their highest development. Sails { 67} increased to eight on the mainmast of a full-rigged ship, and they were better cut and set than ever before. Yachts and merchantmen cannot be fairly compared in the matter of their sails. But it is worth noting that the old 'white-winged days' never had any sort of canvas worth comparing with a British yachting 'Lapthorn' or a Yankee yachting 'Sawyer' of our own time. Hulls, too, have improved far beyond those of the old three-decker age, beyond even the best of the Vikings'.
