This principle will apply with greatly increased force should any European power attempt to establish any new colony in North America. In the existing circumstances of the world the present is deemed a proper occasion to reiterate and reaffirm the principle avowed by Mr. Monroe and to state my cordial concurrence in its wisdom and sound policy. The reassertion of this principle, especially in reference to North America, is at this day but the promulgation of a policy which no European power should cherish the disposition to resist. Existing rights of every European nation should be respected, but it is due alike to our safety and our interests that the efficient protection of our laws should be extended over our whole territorial limits, and that it should be distinctly announced to the world as our settled policy that no future European colony or dominion shall with our consent be planted or established on any part of the North American continent. A question has recently arisen under the tenth article of the subsisting treaty between the United States and Prussia. By this article the consuls of the two countries have the right to sit as judges and arbitrators "in such differences as may arise between the captains and crews of the vessels belonging to the nation whose interests are committed to their charge without the interference of the local authorities, unless the conduct of the crews or of the captain should disturb the order or tranquillity of the country, or the said consuls should require their assistance to cause their decisions to be carried into effect or supported." The Prussian consul at New Bedford in June, 1844, applied to Mr. Justice Story to carry into effect a decision made by him between the captain and crew of the Prussian ship _Borussia_, but the request was refused on the ground that without previous legislation by Congress the judiciary did not possess the power to give effect to this article of the treaty. The Prussian Government, through their minister here, have complained of this violation of the treaty, and have asked the Government of the United States to adopt the necessary measures to prevent similar violations hereafter. Good faith to Prussia, as well as to other nations with whom we have similar treaty stipulations, requires that these should be faithfully observed. I have deemed it proper, therefore, to lay the subject before Congress and to recommend such legislation as may be necessary to give effect to these treaty obligations.
