I went to the rail and gave his air hose a few sharp tugs. 

 Nothing happened. After waiting a few moments, I took 

 hold of the hose again, and this time started to haul it in 

 hand over hand. My tactics finally brought a protesting 

 boy to the foot of the ladder. 



"Oh, Mother, do I have to come up already?" 



He was disgusted and spared no pains to show it as 

 he pulled himself up the ladder and removed his mask and 

 flippers. 



Ed, who had been watching, suddenly exclaimed, 

 "Where is your belt? Didn't you wear one?" 



It developed that eleven-year-old Clayton had been 

 on the bottom for more than three hours without any 

 weights to help keep liim down. It is hard to imagine the 

 amount of effort this required, unless one has tried it; for 

 human lungs, fortified with a generous supply of air from 

 the compressor, create a high degree of flotation in the 

 body. While Clayton had remained on the bottom with 

 no weights whatever, I had found it necessary to wear a 

 twenty-pound lead belt to permit me to stay down with- 

 out exertion. Needless to say, he was tired. But next day he 

 was his usual busy self, much to my relief, for such a long 

 and strenuous immersion at that depth could have had seri- 

 ous consequences. 



Before leaving the wreck of the Spanish galleon to- 

 ward the end of July, Ed rigged the magnetometer behind 

 Sea Diver and carefully patrolled the area between the 

 wreckage of the unfortunate vessel and the outer reef, 

 where she must have first hit. Wherever there was the 

 sHghtest indication of the presence of metal, a yellow buoy 

 was placed. Later the men followed the course laid out by 

 the yellow buoys, tracing their path on the bottom with the 

 metal detector. 



It was apparent, from the frequent indications of
