inding character of a
diplomatic notification or of constructive notice from notoriety.

The subject was brought up at the second Hague Conference (1907). The
Italian and Mexican delegations submitted projects, but after a
declaration by the British delegate in charge of the subject (Sir E.
Satow) that blockade not having been included in the Russian programme,
his government had given him no instructions upon it, the subject, at
his suggestion, was dropped. A _Voeu_, however, was adopted in favour of
formulating rules on all branches of the laws and customs of naval war,
and a convention was agreed to for the establishment of an international
Prize Court (see PRIZE). Under Art. 7 of the latter convention the Court
was to apply the "rules of international law," and in their absence the
"general principles of justice and equity." As soon as possible after

Art. 4. A blockade is not regarded as raised if the blockading force
is temporarily withdrawn on account of stress of weather.

Art. 5. A blockade must be applied impartially to the ships of all
nations.

Art. 6. The commander of a blockading force may give permission to a
warship to enter, and subsequently to leave, a blockaded port.

Art. 7. In circumstances of distress, acknowledged by an officer of
the blockading force, a neutral vessel may enter a place under
blockade and subsequently leave it, provided that she has neither
discharged nor shipped any cargo there.

Art. 8. A blockade, in order to be binding, must be declared in
accordance with Article 9, and notified in accordance with Articles 11
and 16.

Art. 9. A declaration of blockade is made either by the blockading
power or by the naval authorities acting in its name. It specifies (1)
