"2. That effects belonging to the subjects of powers at war be free upon neutral vessels, excepting merchandises of contraband;
"3. That no merchandises be considered as such, but those enumerated in the tenth and eleventh articles of the Treaty of Commerce, concluded between Russia and Great Britain the 28th of June, 1766;
"4. That to determine what characterises a port blocked, this denomination is only to be given to that, where, by the disposition of the power, which attacks it, with vessels sufficiently near, there is an evident danger of entering;
"5. Finally, that these principles serve as rules in proceedings and judgments concerning the legality of prizes.
"And her said Imperial Majesty of all the Russias, having proposed to us, to this effect, to manifest by a formal act of accession, not only our full adhesion to these same principles, but also our immediate concurrence in the measures to assure the execution of them, that we would adopt on our part, by contracting reciprocally with her said Majesty, the engagements and stipulations, following, viz.
"I. That on one part and on the other, we will continue to observe the most exact neutrality, and will carry into the most rigorous execution the prohibitions declared against the commerce of contraband of their respective subjects, with any of the powers already at war, or which may enter into the war in the sequel;
"II. That if, in spite of all the cares employed to this effect, the merchant vessels of one of the two powers should be taken, or insulted, by any vessels whatsoever of the belligerent powers, the complaints of the injured power shall be supported in the most efficacious manner by the other; and that, if they refuse to render justice upon these complaints, they shall concert immediately upon the most proper manner of procuring it by just reprisals;
"III. That if it should happen, that one or the other of the two powers, or both together, on occasion, or in resentment of this present agreement, should be disturbed, molested, or attacked, in such case they shall make common cause between themselves for their mutual defence, and labor in concert to procure themselves a full and entire satisfaction, both for the insult offered to their flag, and for the losses caused to their subjects;
"IV. That these stipulations shall be considered on one part, and on the other, as permanent, and as making a rule, whenever it shall come in question to determine the rights of neutrality;
"V. That the two powers shall communicate amicably their present mutual concert to all the powers who are actually at war.
