“Once we get everything fired up,” Treece said to the Sanderses, “we’ll go down. I’ll take the air gun. David, stay on my left. You ever see an air lift work?”
“No.”
“There’s a tube alongside it that forces compressed air up through it. Creates a kind of vacuum and sucks up the sand. It can buck like a bastard, so stay clear, and don’t get your hands too close to the mouth or it could drag your fingers up inside and cut the crap out of them. It’ll clean sand off the bottom faster’n you can believe. When we uncover ampules, you pick them out as quick as you see them. I’ll have to be bloody careful not to let ’em get sucked up with the sand, or they’ll smash in the gun. And you,” he said to Gail, “stay on his
left. You won’t be able to see a damn thing down there beyond about two feet, so don’t wander. Here.”
He gave her a canvas tote bag. “He’ll pass you the ampules as he gathers them; you put ’em in there. When the bag’s full, you tap him, he’ll tap me, and you’ll lug it up. Don’t come up without telling me;
I need time to move the gun. If I get too far ahead of you, the sand’ll cover the ampules before you can gather ’em. If anything goes wrong, Adam’Us shut off the compressor. It’ll
Okay?”
“Okay,” said Sanders.
“I…” Gail hesitated.
“Say it,” Treece told her. “Get it out now.
I don’t want you springing surprises on me.”
“I don’t like that…” She pointed at the Desco masks and coils of yellow tubing. “It scares me.”
“Why?”
“I don’t know. Claustrophobia, I guess.
I can’t stand the thought of being… tethered. If someone turned off the compressor, I think I’d have a stroke.”
“C’mon,” Sanders said.
“It’s the truth,” she said. “I can’t help it.”
Treece said, “No problem. Rather have you comfortable than all jeebly and upset. Use a tank. We’ve got plenty.”
“Thanks.”
“Anybody got anything else to say, say it now.
Once I fire up that beast, you won’t be able to hear yourselves think.”
“You want wet suits?” Sanders asked.
“Aye. We’ll be down a long time. The water’s warm, but not that warm. After an hour, you’ll be shedding body heat like feathers.” Treece took a screw driver from a tool box, primed the compressor, and touched the screw driver to two contact points on the starter motor. Sparks jumped from the contacts, and the compressor roared to life.
Sanders went below. The cabin of
Gail was threading two-pound weights onto her belt. He gave her a wet suit and said, “What do you normally use, six pounds?”
“Yes.”
“The suit’ll double your buoyancy. You might dump those twos and load up with three or four fours.”
Gail nodded. She saw the knife in his hand.
“What’re you planning to do with that?”
“I don’t know. Dig in the sand. I found it below.”
Treece threw the aluminum tube overboard. It lay on the water for a moment, churning the surface, then slowly sank, trailing the coil of pink tubing behind it. A stream of bubbles popped to the surface.
Treece yelled to Sanders. “Throw that coil over to port. I’ll put mine over starboard. Keep ’em from snarling right off.”
Sanders threw the yellow coil over. It floated, and air bubbled from the face mask. He mounted a harness on a scuba tank, checked the regulator, and helped Gail into the straps. Then he strapped the knife onto his right leg, added ten pounds to his own weight belt, and buckled it around his middle. He wiggled his feet into his flippers and said, “I guess I’m ready. It feels strange: no tank, no mask.”
Gail said, “Throw me the sack when I get myself together, okay?”
“Sure.”
Gail rolled backward off the gunwale. She cleared her mask and held up a hand. Sanders leaned over the side, gave her the handles of the canvas bag; she waved and dove toward the bottom.
Treece went over next, then Sanders-jumping beside the coil of hose, retrieving the mask, and slipping it over his head.
