somewhat similar design and approximate capacities were available from surplus stock at Navy Headquarters, Port Hueneme, California. plus refrigerators were of the portable, These sur- knockdown type but were con- structed with galvanized steel sheets instead of aluminum sheets, However, taking into consideration the comparatively temporary occupancy of the experiment islands, it was felt that the steel refrigerators would be suitable, and of eight 675 cubic foot,six 150 eubdic foot refrigerators were purchased from the Navy for this use. By the end of 1949, the expected maximumpopulation of Parry Island had risen from the 600 man originally contemplated to a total of over 1000 men, It also was apparent that, because of unanticipated delays in water shipments, additional refrigerated storage capacity would be required to provide for 45 day storage periods instead of the 30 day periods originally expected. Therefore, an additional 4-compartment main storage refrigerator was procured for Parry Island.. This was identical to that originally purchased for this location, and in effect doubled the capacity of the permanent storage facilities, It was decided te locate the additional refrigerator in the reefer and commissary building and adjacent to the original main storage refrigerator; the drawings for this building were revised and issued to the field. Since the new refrigerator occupied the space in the building which had been originally allocated to dry storage, & new commissary building was erected adjacent to the mess hall. This new commissary building was a standard 24 foot by 68 foot aluminum building. In August 1950, in discussions between representatives of J-Division and Hojmes & Narver in regard to conditions at the Jobsite, it appeared that refrigeration capacity would be required for a maximum total of 1,668 men on Parry Island, In addition, it also appeared that the hold- iug period between water shipments should be increased again, probably to 60 days. In view of this, it was decided to purchase additional refrigerators from Navy surplus stock to be sent to the field for use as additional temporary storage capacity. Accordingly, six 675 cubic foot. and ten 150 cubic foot portable, knockdown refrigerators were obtained. These refrigerators were installed adjacent to the main refrigerator building on Parry Island, Experience obtained during the construction period indicated that root vegetables could be stored for the extended period between arrivals of refrigerated cargo vessels only by chilling. The continued increase im the number of people to be fed resulted in increased demands for re- frigerated storage space, Root vegetables required only moderate chilling and the type of refrigeration previously provided was not justified for this use, Because of their low rate of heat transfer light weight concrete blocks, which had been shipped to the Jobsite for one of the Air Force test structures and had not been used, were ideally suited as a material with which to construct a chilled vegetable storage building.
