When the Act of Navigation was originally passed, in the Cromwell period, it is probable that the colonies were not seriously in the minds of the people and of Parliament. The act was aimed, as we have before stated, at the Dutch, and was effective for the purposes intended; but within the decade that elapsed before its re-enactment under the Restoration, the colonial trade had grown with a vigor that aroused jealousy and uneasiness at home, and the Act of Navigation was soon followed, in 1663, by the first of the Acts of Trade, which provided that no supplies should be imported into any colony, except what had been actually shipped in an English port, and carried directly thence to the importing colony. This cut the colonies off from direct trade with any foreign country, and made England the depot for all necessaries or luxuries which the colonies desired, and which they could not obtain in America. Nine years later, in 1672, followed another act "for the better securing the plantation trade," which recited that the colonists had, contrary to the express letter of the aforesaid laws, brought into diverse parts of Europe great quantities of their growth, productions and manufactures, sugar, tobacco, cotton, wool and dye woods being particularly enumerated in the list, and that the trade and navigation in those commodities from one plantation to another had been greatly increased, and provided that all colonial commodities should either be shipped to England or Wales before being imported into another colony, or that a customs duty should be paid on such commodities equivalent to the cost of conveying the same to England, and thence to the colony for which they were destined. For instance, if a merchant in Rhode Island desired to sell some product of the colony of Massachusetts in New York, and to forward the same by a vessel, either a bond had to be given that the commodity would be transported to England, or a duty had to be paid, in money or in goods sufficiently onerous to protect the English merchant and shipowner against serious colonial competition in the carrying trade.
