The condition of British navigation in 1651 has been stated. The experience of the remaining years of the Protectorate appears to have confirmed national opinion as to the general policy of the Act, and to have suggested the modifications of the Restoration. To trace the full sequence of development, in legislation or in shipping, is not here permissible; the present need being simply to give an account, and an explanation, of the strength of a national prepossession, which in its manifestation was a chief cause of the events that are the theme of this book. A few scattered details, taken casually, seem strikingly to sustain the claims of the advocates of the system, bearing always in mind the depression of the British shipping industry before the passage of the law. In 1728 there arrived in London from all parts beyond sea 2052 ships, of which only 213 were under foreign flags; less than one in nine. In Liverpool, in 1765, of 1533 entered and cleared, but 135 were foreign; in Bristol, the same year, of 701 but 91 foreign. Of the entire import of that year only 28 per cent, in money value, came from Europe; the carriage of the remaining 72 per cent was confined to British ships. It may, of course, be maintained that this restriction of shipping operated to the disadvantage of the commerce of the kingdom; that there was direct pecuniary loss. This would not be denied, for the object of the Act was less national gain than the upbuilding of shipping as a resource for the navy. Nevertheless, at this same period, in 1764, of 810 ships entering the great North German commercial centre, Hamburg, 267—over one-third—were British; the Dutch but 146, the Hamburgers themselves 157. A curious and suggestive comparison is afforded by the same port in 1769. From the extensive, populous, and fruitful country of France, the entrepôt of the richest West Indian colony, Santo Domingo, there entered Hamburg 203 ships, of which not one was French; whereas from Great Britain there came a slightly larger total, 216, of which 178 were British.

Such figures seem to substantiate the general contemporary opinion of the efficacy of the Navigation Act, and to support the particular claim of a British writer of the day, that the naval weakness of Holland and France was due to the lack of similar measures. "The Dutch have indeed pursued a different policy, but they have thereby fallen to a state of weakness, which is now the object of pity, or of contempt. It was owing to the want of sailors, and not to the fault of their officers, that the ten ships of the line, which during their late impudent quarrel with Britain had been stipulated to join the French fleet, never sailed."[22] "The French Navy, which at all times depended chiefly upon the West India trade for a supply of seamen, must have been laid up, if the war (of American Independence) had continued another year."[23] Whatever the accuracy of these statements,[24]—and they are those of a well-informed man,—they represented a general conviction, not in Great Britain only but in Europe, of the results of the Navigation legislation. A French writer speaks of it as the source of England's greatness,[25] and sums up his admiration in words which recognize the respective shares of natural advantages and sagacious supervision in the grand outcome. "Called to commerce by her situation, it became the spirit of her government and the lever of her ambition. In other monarchies, it is private individuals who carry on commerce; but in that happy constitution it is the state, or the nation in its entirety."

In Great Britain itself there was substantial unanimity. This colored all its after policy towards its lately rebellious and now independent children, who as carriers had revived the once dreaded rivalry of the Dutch. To quote one writer, intimately acquainted with the whole theory and practice of the Navigation Acts, they "tend to the establishment of a monopoly; but our ancestors ... considered the defence of this island from foreign invasion as the first law in the national policy. Judging that the dominion of the land could not be preserved without possessing that of the sea, they made every effort to procure to the nation a maritime power of its own. They wished that the merchants should own as many ships, and employ as many mariners as possible. To induce, and sometimes to force, them to this application of their capital, restrictions and prohibitions were devised. The interests of commerce were often sacrificed to this object." Yet he claims that in the end commerce also profited, for "the increase in the number of ships became a spur to seek out employment for them." In 1792, British registered shipping amounted to 1,365,000 tons, employing 80,000 seamen. Of these, by common practice, two-thirds—say 50,000—were available for war, during which it was the rule to relax the Act so far as to require only one-fourth of the crew to be British. "That the increase in our shipping is to be ascribed to our navigation system appears in the application of it to the trade of the United States. When those countries were part of our plantations, a great portion of our produce was transported to Great Britain and our West India Islands in American bottoms; they had a share in the freight of sugars from those islands to Great Britain; they built annually more than one hundred ships, which were employed in the carrying trade of Great Britain; but since the Independence of those states, since their ships have been excluded from our plantations, and that trade is wholly confined to British ships, we have gained that share of our carrying trade from which they are now excluded."[26] In corroboration of the same tendency, it was also noted during the war with the colonies, that "the shipyards of Britain in every port were full of employment, so that new yards were set up in places never before so used."[27] That is, the war, stopping the intrusion of American colonists into the British carrying trade, just as the Navigation Act prohibited that of foreign nations, created a demand for British ships to fill the vacancy; a result perfectly in keeping with the whole object of the navigation system. But when hostilities with France began again in 1793, and lasted with slight intermission for twenty years, the drain of the navy for seamen so limited the development of the British navigation as to afford an opening for competition, of which American maritime aptitude took an advantage, threatening British supremacy and arousing corresponding jealousy.

Besides the increase of national shipping, the idea of entrepôt received recognition in both the earlier and later developments of the system. Numerous specified articles, produced in English colonies, could be carried nowhere but to England, Ireland, or another colony, where they must be landed before going farther. Because regularly listed, such articles were technically styled "enumerated;" "enumerated commodities being such as must first be landed in England before being taken to foreign parts."[28] From this privilege Ireland was soon after excepted; enumerated goods for that country having first to be landed in England.[29] Among such enumerated articles, tobacco and rice held prominent places and illustrate the system. Of the former, in the first half of the eighteenth century, it was estimated that on an average seventy-two million pounds were sent yearly to England, of which fifty-four million were re-exported; an export duty of sixpence per pound being then levied, besides the cost of handling. Rice, made an enumerated article in 1705, exemplifies aptly the ideas which influenced the multifold manipulation of the nation's commerce in those days. The restriction was removed in 1731, so far as to permit this product to be sent direct from South Carolina and Georgia to any part of Europe south of Cape Finisterre; but only in British ships navigated according to the Act. In this there is a partial remission of the entrepôt exaction, while the nursing of the carrying trade is carefully guarded. The latter was throughout the superior interest, inseparably connected in men's minds with the support of the navy. At a later date, West India sugar received the same indulgence as rice; it being found that the French were gaining the general European market, by permitting French vessels to carry the products of their islands direct to foreign continental ports. Rice and sugar for northern Europe, however, still had to be landed in England before proceeding.

The colonial trade in general was made entirely subservient to the support and development of English shipping, and to the enrichment of England, as the half-way storehouse. Into England foreign goods could be imported in some measure by foreign vessels, though under marked restrictions and disabilities; but into the colonies it was early forbidden to import any goods, whatever their origin, except in English-built ships, commanded and manned in accordance with the Act. Further, even in such ships they must be imported from England itself, not direct; not from the country of origin. The motive for this statute of 1663[30] is avowed in the preamble: to be with a view of maintaining a greater correspondence and kindness between them and the mother country, keeping the former in a firmer dependence upon the latter, and to make this kingdom the staple both of the commodities of the plantations, and of other countries in order to supply them. Further, it was alleged that it was the usage of nations to keep their plantation trade to themselves.[31] In compensation for this subjection of their trade to the policy of the mother country, the supplying of the latter with West India products was reserved to the colonists.

Thus, goods for the colonies, as well as those from the colonies, from or to a foreign country,—from or to France, for example,—must first be landed in England before proceeding to the ultimate destination. Yet even this cherished provision, enforced against the foreigner, was made to subserve the carrying trade—the leading object; for, upon re-exportation to the colonies, there was allowed a drawback of duties paid upon admission to England, and permanent upon residents there. The effect of this was to make the articles cheaper in the colonies than in England itself, and so to induce increased consumption. It was therefore to the profit of the carrier; and the more acceptable, because the shipping required to bring home colonial goods was much in excess of that required for outward cargoes, to the consequent lowering of outward freights. "A regard to the profits of freights," writes a contemporary familiar with the subject, "as much as the augmentation of seamen, dictated this policy."[32] From the conditions, it did not directly increase the number of seamen; but by helping the shipping merchant it supported the carrying industry as a whole.

Upon the legislative union of Scotland with England, in 1707, this entrepôt privilege, with all other reserved advantages of English trade and commerce, was extended to the northern kingdom, and was a prominent consideration in inducing the Scotch people to accept a political change otherwise distasteful, because a seeming sacrifice of independence. Before this time they had had their own navigation system, modelled on the English; the Acts of the two parliaments embodying certain relations of reciprocity. Thenceforward, the Navigation Act is to be styled more properly a British, than an English, measure; but its benefits, now common to all Great Britain, were denied still to Ireland.

It will be realized that the habit of receiving exclusive favors at the expense of a particular set of people—the colonist and the foreigner—readily passed in a few generations into an unquestioning conviction of the propriety, and of the necessity, of such measures. It should be easy now for those living under a high protective tariff to understand that, having built up upon protection a principal national industry,—the carrying trade,—involving in its ramifications the prosperity of a large proportion of the wealth-producers of the country, English statesmen would fear to touch the fabric in any important part; and that their dread would be intensified by the conviction, universally held, that to remove any of these artificial supports would be to imperil at the same time the Royal Navy, the sudden expansion of which, from a peace to a war footing, depended upon impressment from the protected merchant ships. It will be seen also that with such precedents of entrepôt, for the nourishing of British commerce, it was natural to turn to the same methods,—although in a form monstrously exaggerated,—when Napoleon by his decrees sought to starve British commerce to death. In conception and purpose, the Orders in Council of 1807 were simply a development of the entrepôt system. Their motto, "No trade save through England,"—the watchword of the ministry of Canning, Castlereagh, and Perceval, 1807-12,—was merely the revival towards the United States, as an independent nation, of the methods observed towards her when an assemblage of colonies, forty years before; the object in both cases being the welfare of Great Britain, involved in the monopoly of an important external commerce, the material of which, being stored first in her ports, paid duty to her at the expense of continental consumers.

Nor was there in the thought of the age, external to Great Britain, any corrective of the impressions which dominated her commercial policy. "Commercial monopoly," wrote Montesquieu, "is the leading principle of colonial intercourse;" and an accomplished West Indian, quoting this phrase about 1790, says: "The principles by which the nations of Europe were influenced were precisely the same: (1) to secure to themselves respectively the most important productions of their colonies, and (2) to retain to themselves exclusively the advantage of supplying the colonies with European goods and manufactures."[33] "I see," wrote John Adams from France, in 1784, "that the French merchants regard their colonies as English merchants considered us twenty years ago." The rigor of the French colonial trade system had been relaxed during the War of American Independence, as was frequently done by all states during hostilities; but when Louis XVI., in 1784, sought to continue this, though in an extremely qualified concession, allowing American vessels of under sixty tons a limited trade between the West Indies and their own country, the merchants of Marseilles, Bordeaux, Rochelle, Nantes, St. Malo, all sent in excited remonstrances, which found support in the provincial parliaments of Bordeaux and Brittany.[34]

A further indication of the economical convictions of the French people, and of the impression made upon Europe generally by the success of the British Navigation Act, is to be seen in the fact that in 1794, under the Republic, the National Convention issued a decree identical in spirit, and almost identical in terms, with the English Act of 1651. In the latter year, said the report of the Committee to the Convention, "one-half the navigation of England was carried on by foreigners. She has imperceptibly retaken her rights. Towards the year 1700 foreigners possessed no more than the fifth part of this navigation; in 1725 only a little more than the ninth; in 1750 a little more than a twelfth; and in 1791 they possessed only the fourteenth part of it."[35] It is perhaps unnecessary to add that the colonial system of Spain was as rigid as that of Great Britain, though far less capably administered. So universal was the opinion of the day as to the relation of colonies to navigation, that a contemporary American, familiar with the general controversy, wrote: "Though speculative politicians have entertained doubts in regard to favorable effects from colonial possessions, taking into view the expenses of their improvement, defence, and government, no question has been made but that the monopoly of their trade greatly increases the commerce of the nations to which they are appurtenant."[36] Very soon after the adoption of the Constitution, the Congress of the United States, for the development of the carrying trade, enacted provisions analogous to the Navigation Act, so far as applicable to a nation having no colonies, but with large shipping and coasting interests to be favored.
