In 1878, much of the land came under the control of the Casa Miller enterprise, an association between Pérez Reguera and Carlos A. Miller. The enterprise consisted of a soap factory, and land where they raised cattle and grew cotton. The holdings include about 125,000 hectares, centered on Cuajinicuilapa. The town was home to whites. The blacks lived in small huts with thatched roofs based on African-style construction. Product from the enterprise was shipped through Tecoanapa with destination such as Salina Cruz, Manzanillo and Acapulco.
