decks, Sea Diver became unbearable. At night it was im- 

 possible for Ed and me to sleep in our bunks below decks; 

 yet when we moved to the wide seat on the aft deck, we 

 were soon driven below again by swarms of pesky mos- 

 quitoes. Often we slept on the floor of our cabin to catch 

 the least little stir of air. 



The hot wind blew ceaselessly, now and then stepped 

 up by sudden squalls, sweeping in from the sea. Water- 

 spouts moved swiftly across the troubled surface of Florida 

 bay. One night a waterspout passed so close to Sea Diver 

 that every movable object upon her decks was carried off

I welcomed the day when Ed at last proclaimed the 

 magnetometer ready to be tested. With Bill and Ethel 

 accompanying us, we headed for the ivory wreck, and 

 soon had the long tubular instrument overboard, lashed to 

 the bottom of a rubber life raft. As we towed it around the 

 wreck area within cable length of Sea Diver, the boxlike 

 indicator on deck registered some very definite reactions. 



Marking one of the spots where they had received an 

 indication, Ed and Bill dove upon it, and after digging

 They decided to raise the cannon and disappeared under- 

 water with crowbars and hauling chain. Ethel and I went 

 overboard for a swim and watched them through our face 

 plates as they wrestled with their crowbars to free the 

 cannon from the sand. 



We were back on deck when Ed came up to ask for 

 a hoe. While he was waiting at the foot of the boarding 

 ladder, Bill's head popped up beside him. 



"What do you suppose it is?" he said to Ed as he 

 pulled the mask away from his face. 



"Looks to me as if it might be a silver bar," Ed rephed. 



"It's certainly buried deep enough under that old can-
