The projection room was located upon the roof construction at its axis and facing the screen. Access to the projection booth was by means of a vertical wooden ladder at the rear of the shelter, directly behind the booth. The height of the projector lens axis was almost in a horizontal line with the center line of the screen; thus distortion of the projected image was avoided. ENIWETOK ISLAND At the inception of the construction program, there were more than 120 buildings in all stages of deterioration on Eniwetok Island. Some were occupied by the garrison; others were immediately brought into use by construction personnel for temporary quarters, materials warehouses, construction shops, etc. Approximately 50 of these buildings, mostly warehouses, along with several recreation buildings, were repaired and became a part of the semi-permanent facilities of the island. The remainder, consisting mostly of those in the worst state of deterioration, were dismantled after their temporary usefulness to the construction crew was over, or after they had been replaced by new and improved installations, as in the case of the communications, base operations buildings, and the control tower at the airstrip. For the great number of military personnel whose tour of duty on the island was to be of short duration, billetings were accomplished by the use of cantonments containing 8-man tents and 100-man aluminum shower and latrine buildings, For the garrison and for officers and enlisted men to be stationed for a longer period than the duration of the experiments, quarters were provided in 18, 36, and 72-man aluminum barracks, These barracks were the same type of aluminum building as used on Parry Island. Mess hall facilities were planned for an anticipated population of 2200, but actually the facilities ultimately accommodated morethan twice that number for a short length of time. Preliminary studies revealed that the 24-foot width of the standard building was insufficient to allow porper, or even workable, arrangement of equipment necessary to prepare 6,600 meals daily. Nor could adequate seating be provided in this width without making the dining rooms unrealistically long. The two alternatives were the construction of a less permanent building of other materials than aluminum or the adaptation of the standard build- ing to meet the special requirements. sidered the more economical. The latter alternative was con- Standard buildings were used, set in parallel and in the form of a cross, resulting in a building of 504 feet in inside width, with a double row of columns down the center. Two arms of the cross made up the enlisted mens' dining rooms; a third was the officers' dining room, and the fourth and shortest arm contained the kitchen, which extended into the intersection of the cross. The serving area was placed around the perimeter of the inter- section, facing into the three dining rooms, The rear of the kitchen 5-115
