2. Structure with Tunnel Opening 2014

Description:
The stub of a volcanic stone and mortar structure lies directly across and down slope from the adjoined basins. On its east side is a tunnel opening that is connected to the base of the smoke stack. Conceivably, water from the cisterns was channeled toward boilers heated above the structure with the underground tunnel.

3. HRT Fire Tube Boiler 2017

Description:
This intact boiler, one of the two preserved examples, provided the necessary steam required to operate the press engine and other processing equipment. The holes on the end plates suggest that the steam was supplied by a system of horizontal return tubular (HRT) fire tube boilers. Each opening was connected by a horizontal tube to its counterpart on the opposite end. Heat was conducted from the externally-fired dutch oven through each tube via a flue on the back end of the combustion chamber. The multiple tubes created a large surface area for heating the surrounding water within the sealed boiler. At least 114 openings can be counted on one intact boiler end. Deerr (1911:404) calculated that a seven foot diameter boiler with 120 tubes can supply 1800 ft² of heating surface.

4. Water Cisterns

Description:
A large in-ground water retention basin background), measuring approximately 16x9 m and constructed of thick volcanic rock and marine sand mortar walls over 1 m wide and 2 to 3 m high, dominates the northern end of the mill area. An opening at the bottom of the deepest corner of the basin transferred water into a smaller and deeper adjoining water reservoir (foreground) with a metal tube drain imbedded in its west wall. The smaller reservoir is located close to the stone wall with a tunneled flue connected to the smokestack.
