That assent was not likely to be given, so as to become effectual for the purposes for which it had been asked. The action of the States was found, in the spring of 1786, to present a mass of incongruities, which rendered the whole scheme of thus increasing the federal powers almost hopeless. Four of the States had passed laws, conforming substantially to the recommendations of Congress, but restraining their operation until the other States should have complied.[289] Three of the States had passed the requisite acts, and had fixed different periods at which they were to take effect.[290] One State had granted full powers to regulate its trade, by restrictions or duties, for fifteen years, with a proviso that the law should be suspended until all the other States had done the same.[291] Another State had granted power, for twenty-five years, to regulate trade between the respective States, and to prohibit or regulate the importation only of foreign goods in foreign vessels, but restricting the operation of the act until the other States had passed similar laws.[292] Still another State had granted powers like the last, but without limitation of time, and with the proviso that, when all the other States had made the same grants, it should become an Article of the Confederation.[293] The three remaining States had passed no act upon the subject.[294] Upon these conflicting and irreconcilable provisions, Congress could take no other action, than to call the attention of the States again to the original proposal, and request them to revise their laws.[295] While this discordant legislation was manifesting at home the entire impracticability of amending the Federal Constitution by means of the separate action of the State legislatures, the commissioners abroad were engaged in efforts, nearly as fruitless, to negotiate the treaties which they had been instructed to make. The commission was opened at Paris on the 13th of August, 1784, and its objects announced to the different governments. France was not disposed to change the existing relations. England perceived the real want of power in the federal government, and recognized nothing in the commission but the fact that it had been issued by Congress, while the separate States had conferred no powers upon either Congress or the commissioners.[296] Prussia alone entered into a treaty, upon some of the principles laid down in the commission, and soon after it was executed, the commissioners ceased to do any thing whatever.[297]
