The presence of the Trugt Territery ships with their euali crew, on the ether hand, is comuenplace to the islanders. - Plans for the next five years include anaval surveys wiich will gqeraily be reduced in scepe and uuaber of participating pergumael. This ia peasible tor the follewing resasons: (1) Certain types of euaninuations may now be done less f{requentiy then on a yeasly desks; (2) Meee Seo rate and rapid actheds of eumination have been developed; (3) with secent iaprevenent in instrumentation the nunber of specially trained tectnicians required is rewced. In addition, by altemating major prograus, individual surveys uay be reduced in ecege. It ig wmilikely that teams as large as have been used in past surcveys whdl be seeded in the future. This reduction in size ef individual guirveys does net secessarily preclude considerable post-survey axaxinations of sauples returned from the field wich will scaupy the time and effort of a mmber of scicatists at varieus institutions. It gdionld be pointed qut that the number of personnel actually involved in the surveys at Somgelap bag represented a geall ceuponent of the ausbes of acientists amd technicians who have contributed te the sirveys in the laboratories ia the United States.

Por exanple, studies are carried out from arall aliquots ef bleed fer deternination ef bleed groups and gemetically inherited characteristics. Such studies ace Ampertant in agsessing the honogaeity of the population uncer study and in obtaining baseline genctic data, wiich infemmtion is of vital importance in interpreting other observations. The scientific valua of these stucies is secondary te their value in evalusting sdiation effects in the expesed people. Therefore, any inference that the Marahallese peeple are being used as Zuinen pigs because ef guch studies ig completely unjuatified. Details of the March 1960 survey have bean worked cut with Or.
