1. Triple Effect Vacuum Evaporator, Hacienda El Progreso

Description:
This photograph was taken by Capt. Rollo Beck in 1905. It is of a triple effect vacuum evaporator manufactured by McOnie Harvey & Co., Ltd., Glasgow. Sugar was concentrated by passing cane liquor through three vessels, each with an increasingly higher vacuum and lower temperature in order to achieve evaporation. Not only did the evaporator reduce the amount of required fuel through steam re-circulation and evaporation at lower temperatures, but it also protected the sugar product from destruction at higher temperatures.

4. The Hacienda Sugar Mill in 1905

Description:
This image affords a rare view of the entire sugar mill infrastructure shortly after Cobos' death. The view is toward the west from the upper floor of the Hacienda House. The smokestack is barely visible against the horizon toward the middle of the frame. It appears in Las Islas Encantada o el Archipielago de Colon (Bognoly and Epinoza 1905:137).
