But there was an objection made by the State of New Jersey, which should be particularly noticed here, because it foreshadowed the great idea which the Constitution of the United States afterwards embodied. This objection was, that the Articles of Confederation contained no provision by which the foreign trade of the country would be placed under the regulation of Congress. The sixth of the Articles of Confederation declared, that no State should levy any imposts or duties, which might interfere with any stipulations entered into by the United States with any foreign power pursuant to the treaties already proposed to the courts of France and Spain; while the ninth article declared that no treaty of commerce should be made by the United States, whereby the legislative power of the respective States should be restrained from imposing such imposts and duties on foreigners as their own people were subjected to, or from prohibiting the exportation or importation of any species of goods or commodities whatsoever. The effect of these provisions was simply to restrain the States from laying imposts which would interfere with the then proposed treaties; in all other respects, the foreign trade of each State was left to be regulated by State legislation. The legislature of New Jersey, in a very able memorial, laid before Congress on the 25th of June, 1778, declared that the sole and exclusive power of regulating the trade of the United States with foreign nations ought to be clearly vested in the Congress, and that the revenue arising from duties and customs ought to be appropriated to the building and support of a navy for the protection of trade and the defence of the coasts, and to other public and general purposes, for the common benefit of the States. They suggested that a great security would be derived to the Union, from such an establishment of a common and mutual interest.[142] But this suggestion was both premature and tardy. It was premature, because the States had not yet learned that their control over foreign commerce must be surrendered, if they would avoid the evils of perpetual conflict with each other; and it came too late, because the Articles of Confederation were practically incapable of amendment, at the period when the suggestion was made.[143] * * * * *
