upon the eastern coast of Africa, from the 5th degree 12' to the 8th degree south latitude.

Art. 3. His Most Faithful Majesty engages, within the space of two months after the exchange of the Ratifications of this present Convention, to promulgate in His Capital, and in the other parts of His Dominions, as soon as possible, a Law, which shall prescribe the punishment of any of His Subjects, who may in future participate in an illicit Traffic of Slaves, and at the same time to renew the prohibition which already exists, to import Slaves into the Brazils, under any flag, other than that of Portugal; and His Most Faithful Majesty engages to assimilate, as much as possible, the Legislation of Portugal in this respect, to that of Great Britain.

Art. 4. Every Portuguese vessel which shall be destined for the Slave Trade, on any point of the African Coast, where this traffic still continues to be lawful, must be provided with a Royal passport, conformable to the model an nexed to this present Convention, and which model forms an integral part of the same. The passport must be written in the Portuguese language, with an authentic translation in English annexed thereto, and it must be signed, for those vessels sailing from the port of Rio Janeiro, by the Minister of Marine: And for all other vessels which may be intended for the said traffic, and which may sail from any other ports of the Brazils, or from any other of the Dominions of His Most Faithful Majesty not in Europe, the passports must be signed by the Governor in Chief of the Captaincy to which the port belongs: And as to those vessels which

may proceed from the ports of Portugal, to carry on the Traffic in Slaves, their passports must be signed by the Secretary of the Government for the Marine Department.

Art. 5. The two High Contracting Powers, for the more complete attainment of their object, namely, the prevention of all illicit Traffic in Slaves, on the part of their respective subjects, mutually consent, that the ships of war of their Royal Navies, which shall be provided with special instructions for this purpose, as hereinafter provided, may visit such merchant vessels of the two nations, as may be suspected, upon reasonable grounds, of having Slaves on board, acquired by an illicit traffic, and, in the event only of their actually finding Slaves on board, may detain and bring away such vessels, in order that they may be brought to trial before the Tribunals established for this purpose, as shall herein-after be specified.

Provided always, that the Commanders of the ships of war of the two Royal Navies, who shall be employed on this service, shall adhere strictly to the exact tenor of the instructions which they shall have received for this purpose.

As this Article is entirely reciprocal, the two High Contracting Parties engage mutually, to make good any losses which their respective Subjects may incur unjustly, by the arbitrary and illegal detention of their vessels.

It being understood that this indemnity shall invariably be borne by the Government whose cruizer shall have been guilty of the arbitrary detention; provided always, that the visit and detention of Slave ships, specified in this Article, shall only be effected by those British or Portu[1818.] M

guese vessels, which may form part of the two Royal Navies; and by those only of such vessels which are provided with the special instructions annexed to the present Convention,

Art. 6. No British or Portuguese cruizer shall detain any Slave ship, not having Slaves actually on board; and in order to render lawful the detention of any ship, whether British or Portuguese, the Slaves found on board such vessel must have been brought there for the express purpose of the traffic; and those on board Portuguese ships must have been taken from that part of the Coast of Africa where the Slave Trade was prohibited by the Treaty of the 22d of January 1815,

Art. 7. All ships of war of the two nations, which shall hereafter be destined to prevent the illicit Traffic in Slaves, shall be furnished by their own Government with a copy of the instructions annexed to the present Convention, and which shall be considered as an integral part thereof.

These instructions shall be written in Portuguese and English, and signed for the vessels of each of the two Powers, by the Ministers of their respective Marine.

The two High Contracting Parties reserve the faculty of altering the said instructions, in whole or in part, according to circumstances; it being, however, well understood, that the said alterations cannot take place but by common agreement, and by the consent of the two High Contracting Parties.

Art. 8. In order to bring to adjudication, with the least delay and inconvenience, the vessels which may be detained for having been

engaged in an illicit traffic of Slaves, there shall be established, within the space of a year at furthest from the exchange of the Ratifications of the present Convention, two mixed Commissions, formed of an equal number of individuals of the two Nations, named for this purpose by their respective Sovereigns.

These Commissions shall reside one in a possession belonging to His Britannick Majesty the other within the Territories of His Most Faithful Majesty; and the two Governments, at the period of the exchange of the Ratifications of the present Convention, shall declare, each for its own Dominions, in what places the Commissions shall respectively reside. Each of the two High Contracting Parties reserving to itself the right of changing, at its pleasure, the place of residence of the Commission held within its own Dominions, provided, however, that one of the two Commissions shall always be held upon the Coast of Africa, and the other in the Brazils.

These Commissions shall judge the causes submitted to them without appeal, and according to the regulation and instructions annexed to the present Convention, of which they shall be considered as an integral part.

Art. 9. His Britannick Majesty, in conformity with the stipulations of the Treaty of the 22d of January 1815, engages to grant, in the manner hereafter explained, sufficient indemnification to all the Proprietors of Portuguese vessels and cargoes captured by British Cruizers between the 1st of June 1814, and the period at which the two Commissions pointed out in

Article 8, of the present Convention, shall assemble at their respective posts.

The two High Contracting Parties agree that all claims of the nature herein-before-mentioned, shall be received and liquidated by a mixed Commission, to be held at London, and which shall consist of an equal number of the individuals of the two Nations, named by their respective Sovereigns, and upon the same principles stipulated by the 8th Article of this Additional Convention, and by the other acts which form an integral part of the same. The aforesaid Commissions shall commence their functions, six months after the Ratification of the present Convention, or sooner if possible.

The two High Contracting Parties have agreed that the Proprietors of vessels captured by the British Cruizers, cannot claim compensation for a larger number of Slaves than that which, according to the existing Laws of Portugal, they were permitted to transport, according to the rate of tonnage of the captured vessel.

The two High Contracting Parties are equally agreed, that every Portuguese vessel captured with Slaves on board for the traffic, which shall be proved to have been embarked within the territories of the Coast of Africa, situated to the North of Cape Palmas, and not belonging to the Crown of Portugal,-as well as all Portuguese vessels captured with Slaves on board for the traffic, six months after the exchange of the Ratifications of the Treaty of the 22d of January 1815, and on which it can be proved that the aforesaid Slaves, were embarked in the Roadsteds of the Coast of Africa, situated to
