The massive square stone foundation of the 1841 mill chimney and the foundations of the Old Sugar Mill of Koloa still stand, though at present they are covered with a dense grove of trees and brush. In addition to foundation platforms stretching throughout the area, the nearby streams contain structural remains that are evidence of water impoundments, sluices, and diversion channels associated with the mill. The sugar mills were ventures of Ladd and Company and their influence on the Hawaiian economy had been great. As one authority has said, the firm was the first to institute agricultural operations in the islands on an extensive scale and to demonstrate to others the profits that might be obtained from the production of sugar. They inaugurated the Hawaiian system of plantations conducted and financed by central agencies in Honolulu, and the methods of housing and caring for the labor adopted by Mr. Hooper have been continued.
