But I think I know ship-builders who have aever had an education to fit them for understanding these things. fia. Very likely ; but they have followed by rote the rules laid down by cthers; and as they work merely by imitation, they cannot alter or improve as occasion may require. Then, though common merchant ships are intrusted to such builders, yet in constructing men- ol-war and Indiamen, persons of science are always employed. The French, however, attend to this mat- ter more than we do, and, in consequence, their ships generally sail better than ours. Ch. But need a captain of a ship know all these things ? fa. It may not be absolutely necessary; yet occa- sions may frequently arise in which it would be of great advantage for him to be able to judge and give directions in these matters. But suppose the ship built—what comes next ?P Ch. I think she must be rigged. fa, Well—who are employed for this purpose P Ch. Mast-makers, rope-makers, sail-makers, and I know not how many other people. Ha. These are all mechanical trades ; and though in carrying them on much ingenuity has been applied, in the invention of machines and tools, yet we will not stop to consider them. Suppose her, then, rigged-— What next ? Ch, She must take in her guns and powder. Ha, Svop there, and reflect how many arts you have © now set to work. Gunpowder is one of the greatest inventions of modern times, and that which has given such a superiority to civilized nations over the bar- barous.
