9. On arriving at the anchorage of Point Lara, captains who wish to enter the port of Ensenada, will hoist a flag at the mizen-mast, proceed to the vicinity of the fortress, and there wait the health and war visit. They are expressly forbidden to communicate with any person, under the penalties established by the quarantine laws. 10. Ships of war are an exception; they are not required to conform to the above articles. 11. All ships of war, in which the crew may be attacked by a contagious disorder, will hoist a yellow flag, and be subject to the laws of quarantine. ANCHORAGE DUES. For foreign vessels, by the ton, four reals. For national vessels, from foreign parts, two reals. The dues mentioned in the two preceding articles must be paid, half on arrival, and half on the departure of the vessel. National and foreign vessels, which neither take nor receive cargo, will only pay half the dues mentioned above. Foreign vessels will pay, besides, on their entry, twelve dollars for the health visit, and twelve dollars more upon their departure for the health certificate. National vessels only pay half for the visit and the health certificate. The charges for pilots are included in the anchorage dues. POLICE OF THE PORT. Article 1. Every vessel anchored in the port of Buenos Ayres must mutually render each other assistance, in case of drifting, or other risk of average. Those who refuse will be subject to the sentence and penalties prescribed by law. 2. In consequence of the little depth of water, it is expressly enjoined to every vessel anchored in the port to have on its anchors correspondent buoys, as vessels coming in and going out, not seeing the buoys, run a risk of striking on the anchors. Those who fail using precaution in this respect will be responsible for the averages and losses that may result from it. 3. Vessels which have not buoys will give notice to the Captain of the Port, who will send some, with a pilot to place them. The anchor must not be raised without a permission to that effect. 4. At the moment of anchoring, the regular pilots will take care to inform the captains, that they may provide themselves with every thing necessary for the anchorage of their vessels; and if the pilot discovers an infraction of this article, he will immediately inform the Captain of the Port, under the penalty of being himself punished with all the rigour prescribed by law, as negligence in this respect may cause the greatest losses and averages. 5. If, in consequence of bad weather, the anchors and cables of a vessel fail to hold, and it can be proved that those same cables and anchors do not correspond with the size of the vessel, or that the cables were in bad condition, then the said vessel shall be responsible for the averages that may be occasioned thereby.
