This condition, while it lasted, in large degree justified the Navigation Act, which may be summarily characterized as a great protective measure, applied to the peculiar conditions of a particular maritime empire, insuring reciprocal and exclusive benefit to the several parts. It was uncompromisingly logical in its action, not hesitating at rigid prohibition of outside competition. Protection, in its best moral sense, may be defined as the regulation of all the business of the nation, considered as an interrelated whole, by the Government, for the best interests of the entire community, likewise regarded as a whole. This the Navigation Act did for over a century after its enactment; and it may be plausibly argued that, as a war resort at least, it afterwards measurably strengthened the hands of Great Britain during the wars of the French Revolution. No men suffered more than did the West India planters from its unrelieved enforcement after 1783; yet in their vehement remonstrance they said: "The policy of the Act is justly popular. Its regulations, until the loss of America, under the various relaxations which Parliament has applied to particular events and exigencies as they arose, have guided the course of trade without oppressing it; for the markets which those regulations left open to the consumption of the produce of the colonies were sufficient to take off the whole, and no foreign country could have supplied the essential part of their wants materially cheaper than the colonies of the mother country could supply one another."
Thus things were, or were thought to be, up to the time when the revolt of the continental colonies made a breach in the wall of reciprocal benefit by which the whole had been believed to be enclosed. The products of the colonies sustained the commercial prosperity of the mother country, ministering to her export trade, and supplying a reserve of consumers for her monopoly of manufactures, which they were forbidden to establish for themselves, or to receive from foreigners. She on her part excluded from the markets of the empire foreign articles which her colonies produced, constituting for them a monopoly of the imperial home market, as well in Great Britain as in the sister colonies. The carriage of the whole was confined to British navigation, the maintenance of which by this means raised the British Navy to the mastery of the seas, enabling it to afford to the entire system a protection, of which convincing and brilliant evidence had been afforded during the then recent Seven Years' War. As a matter of political combination and adjustment, for peace or for war, the general result appeared to most men of that day to be consummate in conception and in development, and therefore by all means to be perpetuated. In that light men of to-day must realize it, if they would adequately understand the influence exercised by this prepossession upon the course of events which for the United States issued in the War of 1812.
In this picture, so satisfactory as a whole, there had been certain shadows menacing to the future. Already, in the colonial period, these had been recognized by some in Great Britain as predictive of increasing practical independence on the part of the continental colonies, with results injurious to the empire at large, and to the particular welfare of the mother kingdom. In the last analysis, this danger arose from the fact that, unlike the tropical West Indies, these children were for the most part too like their parent in political and economical character, and in permanent natural surroundings. There was, indeed, a temporary variation of activities between the new communities, where the superabundance of soil kept handicrafts in abeyance, and the old country, where agriculture was already failing to produce food sufficient for the population, and men were being forced into manufactures and their export as a means of livelihood. There was also a difference in their respective products which ministered to beneficial exchange. Nevertheless, in their tendencies and in their disposition, Great Britain and the United States at bottom were then not complementary, but rivals. The true complement of both was the West Indies; and for these the advantage of proximity, always great, and especially so with regard to the special exigencies of the islands, lay with the United States. Hence it came to pass that the trade with the West Indies, which then had almost a monopoly of sugar and coffee production for the world, became the most prominent single factor in the commercial contentions between the two countries, and in the arbitrary commercial ordinances of Great Britain, which step by step led the two nations into war. The precedent struggle was over a market; artificial regulation and superior naval power seeking to withstand the natural course of things, and long successfully retarding it.
The suspension of intercourse during the War of Independence had brought the economical relations into stronger relief, and accomplished independence threatened the speedy realization of their tendencies. There were two principal dangers dreaded by Great Britain. The West India plantation industry had depended upon the continental colonies for food supplies, and to a considerable extent also financially; because these alone were the consumers of one important product—rum. Again, ship-building and the carrying trade of the empire had passed largely into the hands of the continental colonists, keeping on that side of the Atlantic, it was asserted, a great number of British-born seamen. While vessels from America visited many parts of the world, the custom-house returns showed that of the total inward and outward tonnage of the thirteen colonies, over sixty per cent had been either coastwise or with the West Indies; and this left out of account the considerable number engaged in smuggling. Of the remainder, barely twenty-five per cent went to Great Britain or Ireland. In short, there had been building upon the western side of the ocean, under the colonial connection, a rival maritime system, having its own products, its own special markets, and its own carrying trade. The latter also, being done by very small vessels, adapted to the short transit, had created for itself, or absorbed from elsewhere, a separate and proportionately large maritime population, rivalling that of the home country, while yet remaining out of easy reach of impressment and remote from immediate interest in European wars. One chief object of the Navigation Act was thus thwarted; and indeed, as might be anticipated from quotations already made, it was upon this that British watchfulness more particularly centred. As far as possible all interchange was to be internal to the empire, a kind of coasting trade, which would naturally, as well as by statute, fall to British shipping. Protective regulation therefore should develop in the several parts those productions which other parts needed,—the material of commerce; but where this could not be done, and supplies must be sought outside, they should go and come in British vessels, navigated according to the Act. "Our country," wrote Sheffield, in concluding his work, "does not entirely depend upon the monopoly of the commerce of the thirteen American states, and it is by no means necessary to sacrifice any part of our carrying trade for imaginary advantages never to be attained."63
A further injury was done by the cheapness with which the Americans built and sold ships, owing to their abundance of timber. They built them not only to order, but as it were for a market. Although acceptable to the mercantile interest, and even indirectly beneficial by sparing the resources for building ships of war, this was an invasion of the manufacturing industry of the kingdom, in a particular peculiarly conducive to naval power. The returns of the British underwriters for twenty-seven shipping ports of Great Britain and Ireland, during a series of years immediately preceding the American revolt, no ship being counted twice, showed the British-built vessels entered to be 3,908, and the American 2,311.64 The tonnage of the latter was more than one-third of the total. The intercourse between the American continent and the West Indies, not included in this reckoning, was almost wholly in American bottoms. The proportion of American-built shipping in the total of the empire is hence apparent, as well as the growth of the ship-building industry. This of course was accompanied by a tendency of mechanics, as well as seamen, to remove to a situation so favorable for employment. But the maintenance of home facilities for building ships was as essential to the development of naval power as was the fostering of a class of seamen. In this respect, therefore, the ship-building of America was detrimental to the objects of the Navigation Act; and the evil threatened to increase, because of a discernible approaching shortness of suitable timber in the overtaxed forests of Europe.
Such being the apparent tendency of things, owing to circumstances relatively permanent in character, the habit of mind traditional with British merchants and statesmen, formed by the accepted colonial and mercantile systems, impelled them at once to prohibitory measures of counteraction, as soon as the colonies, naturally rival, had become by independence a foreign nation. For a moment, indeed, it appeared that broader views might prevail, based upon a sounder understanding of actual conditions
