THE MOVING FINGER WRITES. In the radiation 

 measurement section of the Instrumentation Labo- 

 ratory on the AG-76 "Avery Island," Mr. A. H. 

 Waite, Jr., checks the timing of an automatic pen- 

 and-ink recording device. Recorders like this were 

 used on support ships, several miles off Bikini, to 

 make permanent records of data automatically 

 gathered by instruments on the "hot" target ships 

 within the lagoon. Many of the Geiger counters 

 on the target vessels were used in this way; they 

 were equipped with radio transmitters which auto- 

 matically broadcast the counter readings to these 

 remotely-located recorders. Such continuous rec- 

 ords were available for immediate use, or for 

 more detailed analysis at a later time.
