use of the construction forces. This program would speed up construction and reduce cost. The use of Parry for Laboratory headquarters has certain advantages dur= ing test operations. The scientific aspects of the tests carried on by the Laboratory could be accomplished without the congestion of different chains of command operating in the same camp. Parry island is closer to shot islands than Eniwetok, and, therefore, shortens transportation routes. There is more available real estate on Parry Island, the use of which permits no disturbance of present disposition of garrison forces on Eniwetok Island, and permits more latitude for military expansion on cniwetok. The assumption is made that the weapon assembly will be ship-based, but ample ground space is available on Parry Island to lay out all structures re= quired for a land-based operation. If the decision is made to make this a land-based operation, the necessary changes in planning, design and construc= tion could be quickly and easily made. The advantages appear to be in favor of Parry Island as a base camp for the Laboratory functions, and Eniwetok as a base for other services. This assumption is, therefore, made in following discussions. Island Connections. The islands of the Atoll are connected by a coral reef which is barely awash at low tide. Between Eniwetok Island and Bogallua Island, there is only one break in this reef. is between Parry and Japtan Islands. The so-called "Deep Passage" The idea of connecting the several islands by means of causeways, bridges or combinations has been given consideration. A connection between Eniwetok and Parry Islands would, in effect, make these two islands one, since it would be possible to go from any place on either island by land vehicles, III - 7
