442 PUBLIC TREATIES. Article XIII. Definition of blockade. The high contracting, parties having agreed that a state of war between one of them and a third Power shall not, except in the eases, of blockade and contraband of war, affect the neutral commerce of the other, and being desirous of removing every uncertainty which may hitherto have arisen respecting that which, upon principles of fairness and justice, ought to constitute a legal blockade, they hereby expressly declare that such places only shall be considered blockaded as shall be actually invested by naval forces capable of preventing the entry of neutrals, and so stationed as to create an evident danger on their part to attempt it. Aarrom. XIV. Blockaded ports. And whereas it frequently happens that vessels sail for a port or a place belonging toan enemy without knowing that the same is besieged, blockaded, or invested, it is agreed that every vessel so circumstanced may be turned away from such port or place, but shall not be detained, nor shall any part of her cargo, if not contraband of war, be confiscated, unless, after a warning of such blockade or investment from an etricer commanding a vessel of the blockading forces, by an endorsement of such officer on the papers of the vessel, mentioning the date and the latitude and longitude where such endorsement was made, she shall again attempt to enter; but she shall be permitted to go to any other port or place she shall think proper.
