Here is another treaty which led to the Treaty of Simulambuco between Portugal and the people of Cabinda, namely the Treaty of Chinfuma. This one was signed on the hill of Chinfuma, at Lândana, on 29 September 1883, between Guilherme Augusto de Brito Capelo and the local Princes. The original in Portuguese can be found here: Angola, Cabinda, Tratado de Chinfuma. The river Chiloango referred to in the treaty can be seen on the attached map, as well as the city of Cacongo. Again, the website, Cabinda.net has a lot of these treaties.
========
On the 29th day of the month of September, in the year of Our Lord 1883, on the hill of Chinfuma, at Lândana, on the western coast of Africa, were present on one side, for the Portuguese Government, the Lieutenant-Captain of the Navy, Guilherme Augusto de Brito Capelo, commanding the corvette Rainha de Portugal, and on the other side, for the people inhabiting both banks of the River Kacongo, the Princes and other Notables, now Chiefs and Governors of said people and tribes, who by all present were recognized as the true and identical parties, together with the Portuguese and foreign merchants owning commercial houses at Landana, Chiloango, and on the banks of said river, who volunteered to be present at this meeting as witnesses to all that may be enacted in the premises; being also present Robert F. Hammick, Commander of the English gun-boat Flirt, and the agent of the house Hatton and Cookson, R. E. Dennet; the above mentioned Commander (of the Portuguese corvette) declared that as several Chiefs had expressed the wish of demanding the protection of Portugal, under whose sovereignty they wanted to remain, as being the nation with whom they maintained the most intercourse commercially, as well as in customs and language, ever since Europeans have trod African soil south of the Equator, he, the Commander, now came fully empowered by the Government of His Majesty the King of Portugal to frame a Treaty, which, after being ratified and signed by both Contracting Parties, should establish the future intercourse between Portugal and the countries governed by the subscribing Chiefs. And the Princes and other Notables having formally declared that they wanted to make good, with their signatures, a document by which the Protectorate and sovereignty of Portugal should be clearly authenticated over all the territory lying between the River Massabe (Luiza Loango on the English maps) and the Molembo, 11 Articles were discussed and adopted in a Treaty which, after having been read and duly explained both in Portuguese as well as in the language of the country, was signed by all parties with the sign of a cross, not knowing how to write. And in order that the measures adopted in this solemn meeting might in future be duly authenticated, this statement was made and signed by all parties and attached to the Treaty, which was copied and duly certified and sealed with the seal used on all official documents of the corvette Rainha de Portugal, and copies given to the chief Princes, Tali-e-Tali, Prince Regent of the Kingdom of Kacongo; Mancoche, King of Encoche Luango; Antonio Thiaba da Costa, Regent of the Kingdom of Cinchôcho, representing the Queen of Samano; Mangoal, Prince Regent of Mambuco Manipolo; Antonio Thiaba da Costa, Governor of Massabe, representative of the Chiefs of that place; who also received the Portuguese flag to be hoisted at their Settlements and on the lands that may be ceded to the Portuguese Government, to be kept and defended as the symbol representing the sovereignty and Protectorate of Portugal over the lands governed by them.

lII. Portugal obliges herself to maintain the integrity of the territories placed under its Protectorate.
IV. To the Chiefs of the land and their inhabitants will be maintained the direct ownership of the lands belonging to them, with the right of selling or alienating them in any manner whatever, to establish trading factories, or any private undertaking, on paying the customary fees, and marking clearly and exactly the lands transferred or ceded, to avoid future difficulties; these contracts to be ratified by the Commanders of the Portuguese ships of war.
V. The greatest liberty will be conceded to all merchants of every nationality to settle on these lands, the Portuguese Government holding itself obliged to protect these establishments, retaining, however, the right of proceeding as it may think proper whenever it may be proved that any attempt is made to overthrow the dominion of Portugal.
VI. The Princes and other native Chiefs bind themselves not to make any Treaties, nor to give up any lands to the Representatives of foreign nations in an official capacity, and not with the object mentioned in Article IV.
VII. They likewise bind themselves to protect the commerce of the Portuguese as well as that of the foreigners and of the natives, prohibiting all interruptions in the intercourse with the interior, using their authority to keep open the roads, assisting and protecting the relations between buyers and sellers, religious and scientific Missions that may be temporarily or permanently established on their lands, as well as the development of agriculture.
§. They bind themselves further to prohibit the Traffic in Slaves within the boundary of their dominions.
VIII. Any difficulty arising between Europeans and natives will be settled in the presence of the Commander of the Portuguese ship of war, who on such occasions may be in possible communication with the shore.
IX. Portugal will respect and will cause to be respected the usages and customs of the country.
X.
