In case of war with another nation, "no merchandize heretofore called contraband, such as arms, ammunition and military stores of all kinds,... shall, on any account, be deemed contraband, so as to induce confiscation, and a loss of property to individuals." The right to detain vessels carrying such goods a reasonable length of time was granted, as well as the right not to seize, but "to purchase" military stores with a reasonable compensation to the proprietors; in all cases the owners of the ships delayed were to receive a compensation. But all vessels not carrying contraband were to be entirely free, adding that a blockade in order to be recognized had to be effectual, but even in that case "no vessel of the party who is not engaged in the said war, shall be stopped without a material and well-grounded cause." Besides these general provisions, it was recommended that "each party shall have a right to carry their own produce, manufactures, and merchandise in their own bottoms to the ports of the others, and thence the produce and merchandise of the other, paying, in both cases, such duties only as are paid by the most favored nations." A paragraph was intended specially for the commerce with the West Indies, "desiring that a direct and similar intercourse be admitted between the United States and possessions of the nations holding territorial possessions in America." Finally, as Jefferson as well as his contemporaries were already fearful of seeing any influx of foreigners settle in their country and dominate the infant government, it was stipulated that no right be accorded to aliens to hold real property within these States, this being "utterly inadmissible by their several laws and policy." From the European point of view many things were inadmissible in the plan of treaties. To request the nations of the Old World not only to abandon privateering, but to relinquish their definitions of contraband and their commercial monopolies with their own colonies, was something which must have appeared as the wild dream of a people unexperienced in the handling of foreign relations. As a matter of fact, the treaties were never signed. But if the principles formulated by Jefferson were not accepted by the European powers, they remained nevertheless an essential part of the foreign policy of the United States.
