THE WORLD IS THEIR GARDEN. At an impro- 

 vised field laboratory set up in the very environ- 

 ment they are studying, Lt. Commander M. C. 

 Sargent and T. S. Austin determine concentration 

 of phosphate and oxygen in samples of sea water 

 from a reef section just north of Rongelap Island, 



I 30 miles east of Bikini. Their study was concerned 

 with determining why certain animals and_ plants 

 grow where they do and what factors limit their 

 growth. Studies were made at islands somewhat 

 removed from Bikini to serve as "control'' studies 

 for comparison with data amassed at Bikini.
