"ARTICLE IX. It is necessary to have a scrupulous attention, that there be not on board of any Russian vessel any merchant, clerk, and never more than one third of the seamen, subjects of the belligerent powers, because by conducting differently such vessel might expose herself to sustain disagreeable disappointments. But as a similar inconvenience may easily happen to those sorts of ships, which in time of war are purchased of the subjects of the belligerent powers, for this reason, from this time, and as long as the present maritime war shall last, the said vessels may not be purchased, unless under condition, that they shall be solely employed in the Baltic, or the Black Sea. "ARTICLE X. The carriage of all merchandise whatsoever, into places blocked or besieged by sea and by land, is entirely prohibited, in consequence of which, if any of the merchants of this empire, engaged by the hope of gain, shall intermeddle in any such traffic, whatever loss he may sustain, he cannot ever have the right of demanding our protection. "ARTICLE XI. All our subjects who, by reason of their commerce, find themselves in foreign countries, ought to conform themselves exactly to the civil and mercantile laws, which shall there subsist, as well as to the ordinances of every place where they live, or to which they may send their vessels. Nevertheless, to the end that they may, as much as possible, be instructed in those laws and ordinances, the College of Foreign Affairs will communicate to that of Commerce, all the writings that have relation thereto, that they may be able to give notice of them to the merchants by the means of the public papers.
