"Go as far as you like," responded Seaton, as he placed the women beneath the copper bar--the safest place in the vessel--and leaped to the instrument board. Before he reached it, and while DuQuesne, Crane, and Dunark were hastening to the guns, the whine of giant helicopter-screws was plainly heard. A ranging shell from the first warship, sighted a little low, exploded against the side of the dock beneath them. He reached the levers just as the second shell screamed through the air a bare four feet above them. As he shot the Skylark into the air under five notches of power, a steady stream of the huge bombs poured through the spot where, an instant before, the vessel had been. Crane and DuQuesne aimed several shots at the battleships, which were approaching from all sides, but the range was so extreme that no damage was done. They heard the continuous chattering of the machine gun operated by the Kofedix, however, and turned toward him. He was shooting, not at the warships, but at the city rapidly growing smaller beneath them; moving the barrel of the rifle in a tiny spiral; spraying the entire city with death and destruction! As they looked, the first of the shells reached the ground, just as Dunark ceased firing for lack of ammunition. They saw the palace disappear as if by magic, being instantly blotted out in a cloud of dust--a cloud which, with a spiral motion of dizzying rapidity, increased in size until it obscured the entire city. * * * * * Having attained sufficient altitude to be safe from any possible pursuit and out of range of even the heaviest guns, Seaton stopped the vessel and went out into the main compartment to consult with the other members of the group, about their next move. "It sure does feel good to get a breath of cool air, folks," he said, as he drew with relief a deep breath of the air, which, at that great elevation, was of an icy temperature and very thin. He glanced at the little group of Kondalians as he spoke, then leaped back to the instrument board with an apology on his lips--they were gasping for breath and shivering with the cold. He switched on the heating coils and dropped the Skylark rapidly in a long descent toward the ocean. "If that is the temperature you enjoy, I understand at last why you wear clothes," said the Kofedix, as soon as he could talk. "Do not your planes fly up into the regions of low temperature?" asked Crane. "Only occasionally, and all high-flying vessels are enclosed and heated to our normal temperature. We have heavy wraps, but we dislike to wear them so intensely that we never subject ourselves to any cold." "Well, there's no accounting for tastes," returned Seaton, "but I can't hand your climate a thing. It's hotter even than Washington in August; 'and that,' as the poet feelingly remarked, 'is going some!'
