in 1863 by the National Assembly, and signed a treaty in March of that year. On August 10, Juan Ramón Muñoz, Bolivian Minister Plenipotentiary to Chile, consolidated the agreement with the Chilean Minister of Foreign Affairs, Álvaro Covarrubias. Thus, the Boundary Treaty of 1866 between Chile and Bolivia was concluded, yet never ratified. The treaty stipulated that the 24° parallel would serve as the border between the two nations; the territory between the 23° and 25° parallels would be mutually exploited and profits divided between the two countries; and the right to export the minerals found in the same condominial territory. Bolivia was obligated to open a customs office in Mejillones, and it was to be the only fiscal office which could deal with the production of guano and the exportation rights of the metals in the condominial territory. Between the 24° and 25° parallels, Chile had complete sovereignty and all the rights to import and export without having to declare through customs. Agreement and ratification of the 1874 Treaty The governments that followed Melgarejo also acknowledged the treaty, yet it was not put into effect even then. It was only, as aforementioned, on December 5, 1872, that an agreement was reached between the two nation’s ministers of the exterior, known as the Lindsay-Corral Agreement. After much delay, the treaty was finally signed on August 6, 1874 in Sucre, sealed by the foreign ministers of each nation, Mariano Baptista and Carlos Walker Martínez. The treaty stipulated that the official border between the two countries was the 24° parallel, stretching from the Pacific coast to the Andes cordillera. Between the 23° and 24° parallels, the profits from the exploitation of already existing guanerias, and any further guano to be discovered in the future, were to be divided in half by the two countries. The rights to exploit minerals in the condominial territory was not to increase the quota on what was already being charged at the time. Furthermore, Chilean people and industries could not be levied any further taxes for 25 years after the signing of the treaty. Any Chilean imports entering the Bolivian Litoral through the condominial territory would not be subject to duties nor tariffs. This would apply for Bolivia in the territory between the 24° and 25° parallels. Finally, Chile officially renounced its rights to Mejillones and Antofagasta, for which Bolivia had to provide monetary compensation. The treaty
