“You’ll have to use suction pumps to remove the sand. The lighter she is, the less chance she’ll pull apart. The thick iron plate seems to have stood up well, but the heavy oak planking behind has long since rotted away its strength.”

“We can also remove the guns,” said Folsom. “They’re accessible.”

Pitt examined a copy of the Chenago’s original designs. The Monitor’s familiar shape contained just one circular gun turret, but the Chenago possessed two, one at each end of her hull. From within both turrets extended twin thirty-centimeter Dahlgren smoothbore cannon, weighing several tons apiece.

“The Dollinger tanks,” said Pitt, suddenly thoughtful, “how efficient are they for lifting sunken aircraft?”

Folsom stopped in mid-chew and stared at Pitt. “How big?”

“A hundred and seventy or eighty thousand pounds, including cargo.”

“How deep?”

“One hundred forty feet.”

Pitt could almost hear the gears whirring in Folsom’s brain. Finally the salvagemaster resumed chewing and said, “I’d recommend derricks.”

“Derricks?”

“Two of them on stable platforms could easily lift that much weight,” said Folsom. “Besides, an aircraft is a fragile piece of hardware. If you used the Dollinger tanks and they got the least bit out of synchronization during the lift, they could tear the plane apart.” He paused and looked at Pitt questioningly. “Why all the hypothetical questions?”

Pitt smiled a pondering smile. “You never know when we might have to bring up an airplane.”

Folsom shrugged. “So much for fantasy. Now then, getting back to the Chenago …”

Pitt’s eyes intently followed the diagrams Folsom began drawing on a blackboard. The diving program, the air tanks, the ships on the surface, and the sunken ironclad all took shape in conjunction with Folsom’s running commentary on the planned lift operation. To all appearances, Pitt seemed keenly interested, but nothing he saw was relayed to his memory cells; his mind was two thousand miles away, deep in a Colorado lake.

Just as Folsom was describing the proposed towing procedure once the wreck reached sunlight for the first time in 125 years, a Visalia crewman poked his head through the hatchway and gestured toward Pitt.

“There’s a shore-to-ship call for you, sir.”

Pitt nodded, reached behind him, and picked up a phone sitting on a bulkhead shelf.

“This is Pitt.”

“You’re harder to track down than the abominable snowman,” said a voice through the background static.

“Who is this?”

“Talk about shabby treatment,” said the voice sarcastically, “I slave over a messy desk until three in the morning doing you a favor and you don’t even remember my name.”

“I’m sorry, Paul,” Pitt said, laughing, “but your voice sounds about two octaves higher over the radiophone.”

Paul Buckner, a longtime pal of Pitt’s and an agent of the Federal Bureau of Investigation, lowered his pitch to his belt buckle. “There, is that any better?”
