erator different from that of the two refrigerators previously described in that instead of being housed in an aluminum building it was located on a concrete pad outdoors closely adjoining the building. A section of the wall of the building was omitted to permit the refrigerator doors to swing into the building; this allowed the attendants to enter the refrigerator directly. The refrigerator was constructed of aluminum sheets of the same alloy as the aluminum buildings. Ice is a necessity in the hot, humid climate of the tropics. The cooled drinking water required by each group of men working in the field was supplied in thermo containers filled with ice and water, According to the same basic reasoning that resulted in the selection of package type, sectional walk-in refrigerators, one-ton packaged flake ice machines were chosen for this purpose. Accordingly, in November 1949, a material requisition wes written for the purchase of four one-ton packaged flake ice machines, each com plete with an individual air-cooled refrigeration condensing unit and a one ton storage bin constructed of redwood and equipped with stainless steel liners, It was decided to install these machines in the reefer and commissary building on Parry Island, and the drawings for this building were revised and reissued with this change to the field. Late in December 1949 and in Jamary 1950, the design of the reefer building for Eniwetok Island was firmed up. By this time, the expected maximum population of this island had increased from the 600 men con- templated in the Reconnaissance Report to over 1800 men. i/ccordingly, the main refrigeration facilities provided in the plans of this island consisted of six flake ice machines and four 5—compartment refrigerators, all identical in design to those for use on Parry Island. This equipment was all contained in one standard 24 foot wide alumimm building approximately 236 feet long. The four refrigerators were installed end- to-end in one continous line over 200 feet long. In addition to the main storage refrigerators for Eniwetok Island, the mess hall was provided with a three-compartment refrigerator of similar design to that installed in the mess hall on Parry Island. Two compartments of this refrigerator were designed for storage of vegetables and dairy products at 389 F, and the third compartment was designed for storage of frozen foods at 0° F, Also in January 1950, a specification was written for the procurement of food storage refrigerators and beverage storage refrigerators for the experiment island camps. These were specified to be aluminum-clad, knock~ down, walk-in refrigerators similar in design to those previously des- cribed but of mich smaller capacity. It was contemplated that prior to the experiments these refrigerators, along with other items of a portable nature, would be dismantled and removed to Parry Island for storage. This specification was delivered to the Holmes & Narver Purchasing Department for action in procuring the specified refrigerators, but be- fore such action had been initiated it was learned that refrigerators of 5-266
