He saw that Sallorsen and Lawson had answered his call; man after man was clad in his suit and sucking in the incomparably fresher, though artificial, air of the units. As he had hoped, that air was revitalizing the worn-out bodies rapidly, giving them new strength and clearing their brains. His plan required that—strength for the men to move and act for themselves—sane heads!
The plan was basically simple. Bringing his best concentration to the all-important details, Ken started to build the road to the world above.
First he opened the inner door of the starboard port-lock, wherein lay his torpoon. Opening the entrance panel of the steel shell, he quickly transferred within the cans of compressed food retrieved from the second compartment. When he had finished, there was left barely room for the pilot's body.
And then the nitromite.
The explosive was carried by the Peary for the blasting of such ice floes as might trap her. It was contained for chemical stability in a half dozen six-inch-square, water-proof boxes, strung one after another on an interconnecting wired rope. Ken would need them all; he wished he had five times as many. It would not matter if the whole of the Peary were shattered to slivers.
Ken tied the rope of boxes into a strong unit, as small as it could be made. Firing and timing mechanisms were contained in each unit: he would only have to set one of them. He wrapped the whole charge, except for one small corner, in several pieces of the men's discarded clothing—monkey jackets, thick sweaters, a dirty towel—and stuffed it in an empty tin container for sea-biscuits.
All this had taken only minutes. But in those minutes the quarsteel of the watertight door had been subjected to half a dozen smashing blows, and already a flaw had appeared in the pane. Another grinding crunch, and there would be the visible beginning of a crack. Three more, perhaps, and the door would be down.
But the plan was laid, the counter move ready; and, as Sallorsen and Lawson, last of them all, got into suits, Ken Torrance, in short, gasping sentences, explained it.
"All the nitromite's in this," Ken said. "I hope it's enough. In a moment I'll set the timing to explode it in one minute—then eject it from the empty torpoon port-lock. It's a gamble, but I think the explosion should kill every damned seal around the sub. Water carries such shocks for miles, so it should stun, if not kill, all the others within a long radius. See? We're inside sub, largely protected. When the stuff explodes, you and men make for the hole you blew in the ice above."
