It is expected that the animals shall become accustomed to the South Pacific climate by the time the shots are made. (e) Living and Headquarter Sites. In order to expedite the scientific work program living quarters are considered necessary on the shot island sites and at the site of the scientific operations headquarters. Each shot island camp must house an estimated two hundred people and should be temporary in nature since it will be destroyed by the blast. In addition it was decided to use Parry Island for the headquarters for all 4rc snerations, and semi-permanent living quarters for 600 personnel and temporary quarters for 200 personnel at peak load periods is required.

Likewise, wherever practical it was specified that utilities for the shot island work camps be made semipermanent in nature, installed in bomb-proof shelters where practical. Since the assistance of the military services is required in all such test operations as these, it was decided that the AEC should
