Between 1660 and 1770 Parliament enacted various laws whose enforcement produced irritation from the beginning, and had no inconsiderable influence in promoting the final rupture. These acts may be classed as,—First, navigation laws, designed to secure the naval and maritime supremacy of Great Britain throughout the world; these were aimed at the Dutch. Second, acts of trade, procured by the mercantile class, to monopolize the trade of the British colonies. Like the corn-laws of a later generation, these formed part of the protective system, and were dictated by class interest. Third, acts for the protection of British manufactures by preventing their growth in the colonies, where their best market was found. Fourth, acts designed to secure the strict execution of the preceding acts by establishing colonial admiralty courts, custom-houses, and boards of customs. Fifth, acts which imposed and regulated duties and port charges in commercial towns. In no sense were these acts for revenue, British or colonial. They brought nothing into the British Exchequer, but drew large sums from it.[12] They were passed solely in the interest of the mercantile and manufacturing classes, whose protection had much to do with bringing on the Revolution, but whose clamors happily prevented efficient measures for its suppression. These demonstrations, which gained them great credit in the colonies, grew out of their fear of losing not only the £4,000,000 due by their colonial debtors, but also their future trade.

Before the Grenville Act of 1764 no measures had been taken to relieve the Exchequer from demands on account of the colonies. The people and the government had suffered the mercantile and manufacturing classes to dictate their colonial policy. Not that the prosperity of these classes did not contribute to the general prosperity of the realm; for, on the contrary, it had made Great Britain the most affluent and powerful country on the globe. But this system did not promote the welfare of all classes alike; and when the time came, as it did after the frightful expenditure in the French War, that the Chancellor of the Exchequer was compelled to ask for ready money to pay the interest on the debt and to meet current expenses, neither the merchants nor the manufacturers, who had grown rich by the war, offered on that account to pay larger taxes, but they were quite willing that the British farmer should do so, or that a revenue should be sought from the American colonies.

Some account of these famous laws is essential at this point. There were three statutes embraced under the general term Navigation Laws and Acts of Trade, in which are to be found the principles of the Mercantile System. They were passed in 1660, 1663, and 1672, during the reign of Charles II., and may be found in the Statutes at Large,[13] with the following titles respectively: "An Act for the Encouraging and Increasing of Shipping and Navigation", "An Act for the Encouragement of Trade", and "An Act for the Encouragement of the Greenland and Eastland Trades, and for the Better Securing the Plantation Trade."[14]

The navigation laws will be more readily understood if we attend solely to their effect on the American colonies, and disregard unimportant exceptions and limitations. By the act of 1660, none but English or colonial ships could carry goods to or bring them from the colonies. This excluded all foreigners, and especially the Dutch, who at that time were the principal carriers for Europe. The result was that the colonists lost the advantage of their competition. Far more serious was the provision which restricted them from carrying sugar, tobacco, cotton, wool, indigo, ginger, fustic and all other dyeing wood, the product of any English colony, to any part of the world, except Great Britain, or some other English colony. This affected the English sugar islands of the West Indies and the Southern colonies, which were obliged to send their products to the overstocked English or colonial markets, more than it affected New England, whose great staples, lumber, fish, oil, ashes, and furs, were free to find their best market, provided only they were sent in English or colonial vessels.

British merchants not satisfied with this monopoly procured a more stringent act in 1663, which provided that no commodity, the growth, product, or manufacture of Europe, should be imported into the colonies, except in English-built ships, sailing from English ports. By this act England became the sole market in which the colonists could purchase the products or manufactures of Europe, nor could they send their own ships for them, unless English-built or bought before October 1, 1662. They were obliged to buy in English markets and import in English vessels.[15] This discouraged ship-building for the European trade in a country full of timber, and compelled the payment of charges and profits to English factors dealing in Continental goods for the American market.

By these two acts British merchants had undertaken to monopolize, with certain exceptions, the carrying trade of the colonies and their markets for the sale and the purchase of goods. But avarice was not satisfied. There had grown up a trade, especially profitable to New England, with the Southern colonies which were without shipping. By the act of 1660, foreign and intercolonial trade in certain articles was permitted, with the expectation that it would be limited to necessary local supply. But Boston merchants, shipping to that port tobacco and some other colonial products in excess of the local demand, sent the surplus to Continental Europe, without payment of British or colonial duties, and thus undersold the British trader, who had paid heavy import duties. To suppress this profitable irregularity, it was enacted in 1672 that the enumerated products shipped to other colonies should be first transported to England, and thence to the purchasing colony. The colonial merchants had the option, however, of bringing tobacco, for instance, from Virginia direct to Massachusetts, first paying an export duty equivalent to the English import duty.[16]

These enactments subjected colonial interests to those of British ship-owners and merchants; and as they had been thus duly protected, the manufacturers in turn claimed similar protection by statutes which should prevent the colonists from setting up competing manufactories.[17] How could there have been any difference of opinion among the colonists respecting such statutes? A general answer is, that the colonial system, which regarded the colonies as feeders for the navigation, trade, and manufactures of the parent state, was the accepted doctrine of European statesmen. Pitt was its stanchest advocate, and Burke its rational friend. Adam Smith, who assaulted it in 1776,[18] did not succeed in overthrowing it. Twenty-five years later, Henry Brougham controverted Smith's views.[19] It is not strange, therefore, that it found advocates among the colonists themselves. It was also far from being a one-sided question.

James Otis's arguments on the Writs of Assistance and John Adams's letters to William Tudor, by dwelling on the injurious features of these acts, and passing over all compensating considerations, give an erroneous notion of them. The idea that they originated in a hostile disposition of the British people or merchants towards the colonists is not entitled to a moment's consideration. They formed a commercial policy, not a political policy. The more numerous, wealthy, and prosperous the colonists became, the more useful they were to the British merchants, so long as they could monopolize the trade. That was their object; and where the freedom of colonial trade would not interfere with British trade, it was left free. For example, the most profitable trade of New England was with the French and Spanish West India Islands and the Spanish Main. The short distance favored small vessels and small capitals. The exchange of lumber, grain, cattle, and fish for sugar and molasses, with an occasional voyage to the coast of Africa for slaves, during that traffic,[20] yielded rich returns. This trade was free; and so was that of Asia and Africa, and some ports of Europe, except for certain enumerated articles. It was not only permitted, but with respect to some commodities was encouraged by bounties. Between 1714 and 1774, the colonists, chiefly those of New England, received £1,609,345 sterling on their commodities exported to Great Britain;[21] and through a system of drawbacks, by which the duties on goods imported into England were repaid on their exportation to America, the colonists often bought Continental goods cheaper than could the subjects within the realm. These favors no more indicated good will than the restrictions indicated hostility. Both rested on purely commercial considerations. There were other compensations. The naval supremacy of Great Britain, due chiefly to the navigation laws, protected colonial commerce in whatever seas it was pushed; and the stimulus of monopoly withdrew British capital from other less lucrative enterprises, and directed it to the colonies, where it was freely used by planters in developing lands which otherwise would have been uncultivated for lack of capital.[22] And although certain colonial produce was obliged to find its only European market in England, it had the monopoly of that market.

If it was a hardship to the tobacco growers of Maryland and Virginia to be compelled to send that product to England, they had this advantage, that no Englishman could use any other. He was forbidden by penal statutes to grow his own supply even in his own garden. As to those laws which restrained manufactures in the colonies, it was the opinion of Henry Brougham,[23] who cites Franklin as an authority, that they merely prohibited the colonist from making articles which could have been more cheaply purchased.[24] He could import a hat from England for less than it cost to make one, and he did so. But the best ground for nominal submission to the navigation laws and acts of trade was found in their easy evasion, and the fact that they never were, and never could have been, rigidly enforced. From the first, all attempts to enforce them led to dissatisfaction. Randolph's revenue seizures in the time of Charles II. and James II. had no small influence in overthrowing Andros's government in the revolution of 1689, and so had Charles Paxton's in bringing on the American Revolution.

Before the new policy of enforcing these laws was entered upon, the colonies enjoyed British naval protection; they possessed the monopoly of the British market; they drew bounties from the British Exchequer; they purchased European goods more cheaply than the British people could do; and, stating the facts somewhat broadly, they manufactured whatever they found to be for their advantage, and sent their ships wherever they pleased, notwithstanding the navigation laws and acts of trade. The result was that the colonies, especially barren and frozen New England, engrossed most profitable commerce which England had attempted to monopolize, and increased in wealth beyond all colonial precedent.[25] But these halcyon days were destined to pass under clouds. British merchants had seen from the beginning the amassing of fortunes in the colonies by illicit trade, and the falling off of their own. They had striven to enforce the laws, and Parliament had lent its assistance,—but in vain. Under the first charter of Massachusetts, the collector of customs was the governor, whose annual election depended upon the good will of those who were evading the navigation laws; under the second charter, the governor was appointed by the king, and sworn to enforce those laws. But colonial juries generally checkmated the king's representative. Then followed admiralty courts without juries, which produced indignant protests. The new system was irritating rather than efficient on a long line of coast filled with bays, creeks, and ports not patrolled by revenue cutters. The British merchant was foiled, and anger was the result. The attempt to monopolize the commerce of the colonies was a failure; and so long as the navigation laws were a dead letter the advantages of the situation were with the colonists. They were content.
