may be introduced into the old markets, yet many new markets will be opened by increasing population, enlarging old and erecting new towns, augmenting individual and aggregate wealth, and extending foreign commerce. The prosperity of ancient Egypt, and China, may in a great degree be attributed to their inland navigation. With little foreign commerce, the former of those countries by these means attained and the latter possesses, a population and opulence in proportion to their extent, unequalled in any other. And England and Holland, the most commercial nations of modern times, deprived of their canals, would lose the most prolific sources of their prosperity and greatness. Inland navigation is in fact to the same community what exterior navigation is to the great family of mankind. As the ocean connects the nations of the earth, by the ties of commerce and the benefits of communication, so do lakes, rivers, and canals operate upon the inhabitants of the same country: and it has been well observed, that "were we to make the supposition of two states, the one having all its cities, towns, and villages upon navigable rivers and canals, and having an easy communication with each other; the other possessing the common conveyance of land carriage, and supposing both states to be equal as to soil, climate, and industry, commodities and manufactures in the former state, might be furnished thirty per cent. cheaper than in the latter: or in other words, the first state would be a third richer, and more affluent than the other."
