The nitrate
oficina (saltpeter mine) of Marusia was located in the foothills of the Andes in the
región de Tarapacá, about 4 miles northwest of the town of
Huara. Its monthly production was 865 tons of salt. In March 1925, the mine workers went on strike to demand higher pay, a shorter workday, and better working conditions. While negotiations were taking place between the company executives and the workers' representatives, the British engineer who ran the mine, a man much hated because of his habit of whipping his workers, was found dead near the mine. A Bolivian engineer was accused of the crime and executed without due process by decision of the company owners. ==Events==
