The pumps are mighty, house-sized things; they have to be to fight the back-pressure that they are going to engender. Goto Dengo’s young engineers see to it that they are mated into the two vertical holes on top: one to supply compressed air, the other pressurized fuel oil. Doug Shaftoe would like to be involved in this, but he knows it’s over his head technically, and he’s got other duties: securing the defensive perimeter against gold-seekers and whatever creepy-crawly individuals Wing might have sent out to harass and sabotage them. But Doug has put the Word out, and a whole lot of Doug’s very interesting and well-traveled friends have converged on Golgotha from all over the world and are now camped out in foxholes in the jungle, guarding a defensive perimeter strung with monofilament tripwires and other stuff that Randy doesn’t even want to know about. Doug just tells him to stay away from the perimeter, and he does. But Randy can sense Doug’s interest in the central project here, and so when the big day comes, he lets Doug be the one to throw the switch.
