218 ANNUAL REGISTER, 1818. 



this service shall adhere strictly 

 to the exact tenor of the instruc- 

 tions which they shall receive for 

 this purpose. As this article is 

 entirely reciprocal, the two high 

 contracting parties engage mu- 

 tually, to make good any losses 

 which their respective subjects 

 mayjncur unjustly by the arbi- 

 trary and illegal detention of 

 their vessels. It being understood 

 that this indemnity shall invari- 

 ably 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, spe- 

 cified in this article, shall only be 

 effected by those British or 

 Spanish 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 treaty. 



Art. 10. No British or Spanish 

 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 Spanish, the 

 slaves found on board such vessel 

 must have been brought there for 

 the express purpose of the traffic; 

 and those on board of Spanish 

 ships must have been taken from 

 that part of the coast of Africa 

 where the slave trade is pro- 

 hibited, conformably to the tenor 

 of the present treaty. 



Art. 11. All ships of war of 

 the two nations, which shall here- 

 after be destined to prevent the 

 illicit traffic in slaves, shall be 

 furnished by thuir own govern- 

 ment with a copy of the instruc- 

 tions annexed to the present 

 fcreaty, and which shall be con- 



sidered as an integral part there- 

 of. These instructions shall be 

 written in Spanish and English, 

 and signed for the vessels of each 

 of the two powers, by the minister 

 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 under- 

 stood, that the said alterations 

 cannot take place but by the 

 common agreement, and by the 

 consent of the two high contract- 

 ing parties. 



Art. 12. 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 establish- 

 ed, within the space of a year at 

 farthest, from the exchange of 

 the ratifications of the present 

 treaty, two mixed commissions, 

 formed of an equal number of 

 individuals of the two nations, 

 named for this purpose by their 

 respective sovereigns. These com- 

 missions shall reside — one in a 

 possession belonging to his Bri- 

 tannic Majesty — the other within 

 the territories of his Catholic 

 Majesty ; and the two govern- 

 ments, at the period of the ex- 

 change of the ratifications of the 

 present treaty, shall declare, each 

 for its own dominions, in what 

 places the commissions shall 

 respectively reside. Each of the 

 two high contracting parties re- 

 serving to itself the right of 

 changing, at its pleasure, the 

 place of residence of the commis- 

 sion held within its own domi- 

 nions ; provided, however, that 

 one of the two commissions
