Both the Egyptians and Indians must have depended almost altogether upon the navigation of other nations for the exportation of their surplus produce; and this dependence, as it must have confined the market, so it must have discouraged the increase of this surplus produce. It must have discouraged, too, the increase of the manufactured produce more than that of the rude produce. Manufactures require a much more extensive market than the most important parts of the rude produce of the land. A single shoemaker will make more than three hundred pairs of shoes in the year; and his own family will not perhaps wear out six pairs. Unless therefore he has the custom of at least fifty such families as his own, he cannot dispose of the whole produce of his own labor. The most numerous class of artificers will seldom, in a large country, make more than one in fifty or one in a hundred of the whole number of families contained in it. But in such large countries as France and England, the number of people employed in agriculture has by some authors been computed at a half, by others at a third, and by no author that I know of, at less than a fifth of the whole inhabitants of the country. But as the produce of the agriculture of both France and England is, the far greater part of it, consumed at home, each person employed in it must, according to these computations, require little more than the custom of one, two, or, at most, of four such families as his own, in order to dispose of the whole produce of his own labor. Agriculture, therefore, can support itself under the discouragement of a confined market much better than manufactures. In both ancient Egypt and Hindustan, indeed, the confinement of the foreign market was in some measure compensated by the convenience of many inland naviga-
