Nerado's looped neck straightened convulsively as his tortured drivers whined and shrieked at the terrific overload; but Roger's effort was far too intense to be long maintained. Even before his accumulators failed, generator after generator burned out, the defensive screen collapsed, and the red converter beam attacked voraciously the unresisting metal of those prodigious walls. Soon there was a terrific explosion as the pent-up air of the planetoid broke through its weakening container, and the sluggish river of allotropic iron flowed in an ever larger stream, ever faster. "It is well that we had an unlimited supply of iron." Nerado tied a knot in his neck and spoke in huge relief. "With but the seven pounds remaining of our original supply, I fear that it would have been difficult to parry that last thrust." "Difficult?" asked the second in command. "We would now be swimming in space. But what shall I do with this iron? Our reservoirs will not hold it all." "Seal up one or two of the lower storage compartments, to make room for this lot. Immediately it is loaded, we return to Nevia. There we shall install reservoirs in all the spare space, and come back here for more." The last drop of the precious liquid secured, the vessel moved away, sluggishly now because of its prodigious load. In their quarters in the fourth section the three Terrestrials, who had watched with strained attention the downfall and absorption of the planetoid, stared at each other with drawn faces. Clio broke the silence. "Oh, Conway, this is ghastly! It's ... it's just simply perfectly horrible!" she gasped, then recovered a measure of her customary spirit as she stared in surprise at Costigan's face. For it was thoughtful, his eyes were bright and keen--no trace of fear or disorganization was visible in any line of his hard young face. "It's not so good," he admitted frankly. "I wish I wasn't such a dumb cluck--if Lyman Cleveland or Ford Rodebush were here they could help a lot, but I don't know enough about any of their stuff to flag a hand-car. I can't even interpret that funny flash--if it really was a flash--that we saw." "Why bother about one little flash, after all that really did happen?" asked Clio, curiously. "You think Roger launched something? He couldn't have--I didn't see a thing," Bradley argued. "I don't know what to think. I've never seen anything material sent out so fast that I couldn't trace it with an ultra-wave--but on the other hand, Roger's got a lot of stuff that I never saw anywhere else. However, I don't see that it has anything to do with the fix we're in right now--but at that, we might be worse off. We're still breathing air, you notice, and if they don't blanket my wave I can still talk." He put both hands in his pockets and spoke.
