The want of a power to regulate commerce is by all parties allowed to be of the number. The utility of such a power has been anticipated under the first head of our inquiries; and for this reason, as well as from the universal conviction entertained upon the subject, little need be added in this place. It is indeed evident, on the most superficial view, that there is no object, either as it respects the interests of trade or finance, that more strongly demands a federal superintendence. The want of it has already operated as a bar to the formation of beneficial treaties with foreign powers, and has given occasions of dissatisfaction between the States. No nation acquainted with the nature of our political association would be unwise enough to enter into stipulations with the United States, by which they conceded privileges of any importance to them, while they were apprised that the engagements on the part of the Union might at any moment be violated by its members, and while they found from experience that they might enjoy every advantage they desired in our markets, without granting us any return but such as their momentary convenience might suggest. It is not, therefore, to be wondered at that Mr. Jenkinson, in ushering into the House of Commons a bill for regulating the temporary intercourse between the two countries, should preface its introduction by a declaration that similar provisions in former bills had been found to answer every purpose to the commerce of Great Britain, and that it would be prudent to persist in the plan until it should appear whether the American government was likely or not to acquire greater consistency.(1) Several States have endeavored, by separate prohibitions, restrictions, and exclusions, to influence the conduct of that kingdom in this particular, but the want of concert, arising from the want of a general authority and from clashing and dissimilar views in the State, has hitherto frustrated every experiment of the kind, and will continue to do so as long as the same obstacles to a uniformity of measures continue to exist.
