The sky to windward grew blacker and blacker. There was no longer a steady flow of wind coming over the cliff's edge. It came in gusts, now, of extreme violence. They could make a man stagger on his feet. There were more flecks of white on the ocean's surface.
"The boats," added Sandringham, "were licked. There simply wasn't enough oil to maintain the slick. The radio reports were getting hysterical before I ordered them told that we had it beaten on shore. They're running for shelter now. I think they'd have stayed out there trying to hold the slick in place with their tow-line, if I hadn't said we had matters in hand."
Werner said, tight-lipped:
"I hope we have!"
Bordman shrugged.
"The wind's good and strong, now," he observed. "Let's find out. You've got the starting system all set?"
Sandringham waved his hand toward a high-voltage battery. It was of a type designed for blasting on airless planets, but that did not matter. Its cables led snakily for a couple of hundred feet to a very small pile of grayish soil which had been taken out of a bore-hole, and went over that untidy heap and down into the ground. Bordman took hold of the firing-handle. He paused.
"How about the highways?" he asked. "There might be some steam out of this hole."
"All allowed for," said Sandringham. "Go ahead."
There was a gust of wind strong enough to knock a man down, and a humming sound in the air, as wind beat upon the four-thousand-foot cliff and poured over its top. There were gradually rising waves, below. The sky was gray, the sea slate-colored. Far, far to windward, the white line of pouring rain upon the water came marching toward the island.
