"Now, sir, we'll see what can be done about the new berg. You say there's no plume of steam. Have you had an aëroplane fly above it to make sure?" "Yes. The pilot says the whole ice cake is covered with mist, except for a round spot in the middle, but there's no sign of a steam plume." Teddy nodded at Evelyn. "No holes in this cold bomb. I wonder what happens to all the heat that comes in?" "Father mentioned that he expected something of the sort, but didn't say what he thought could be done about it." "The same as we did with the other, I suppose," said Teddy reflectively. "Only this time we'll have to blast down to the bomb and then break it up." "I'll set men to work if you'll find the bomb," said the commandant. "Almost any one could find it," Teddy remarked, "but there are going to be some queer difficulties when you get near the cold bomb. If you'll allow me, I'd like to be at hand when it is broken up. I may really be of use there." He began to pick out instruments he thought he might need. Among other things he took what seemed to be two silvered globes with small necks. They were Dewey bulbs. Several low-temperature thermometers and a thermocouple connected with a delicate galvanometer completed his preparations. The two men left the house and started for the launch that would take them to the forts. On the way Teddy was asking crisp questions about the explosives he could have placed at his disposal, quite ignorant of what was happening at that moment in Jacksonville.
