OVER THE HUMP. When this photograo^ «vas 

 made the column of water had just aboi't reached 

 the top of its rapid climb. Its rr>o+ + !ed surface has 

 been replaced by individual jets or spurs each one 

 of which is approximately the size of a large ship. 

 In another moment the huge column begins its 

 ominous descent. The condensation cloud is still 



present. In Test Baker the air blast wave was far 

 less intense than it had been in Test Able. There 

 was little optical radiation of any significance. Due 

 to absorption of neutrons and gamma rays by the 

 water of the Lagoon, the first flash of nuclear radia- 

 tion had very little immediate effect on the target 

 ships.
