Roger experimented briefly with inertialessness. No use. As he had expected, they were prepared for that. He summoned a few of the ablest of his scientist-slaves and issued instructions. For minutes a host of robots toiled mightily, then a portion of the shield bulged out and became a tube extending beyond the attacking layers of force; a tube from which there erupted a beam of violence incredible. A beam behind which was every erg of energy that the gigantic mechanisms of the planetoid could yield. A beam that tore a hole through the redly impenetrable Nevian field and hurled itself upon the inner screen of the fish-shaped cruiser in frenzied incandescence. And was there, or was there not, a lesser eruption upon the other side--an almost imperceptible flash, as though something had shot from the doomed planetoid out into space? Nerado's neck writhed convulsively as his tortured drivers whined and shrieked at the terrific overload; but Roger's effort was far too intense to be long maintained. 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 almost tied a knot in his neck as he 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 free atoms in space. But what shall I do with this iron? Our reservoirs will not hold more than half of it. And how about that one ship which remains untouched?" "Jettison enough supplies from the lower holds to make room for this lot. As for that one ship, let it go. We will be overloaded as it is, and it is of the utmost importance that we get back to Nevia as soon as possible." This, if Gharlane could have heard it, would have answered his question. All Arisia knew that it was _necessary_ for the camera-ship to survive. The Nevians were interested only in iron; but the Eddorian, being a perfectionist, would not have been satisfied with anything less than the complete destruction of every vessel of Triplanetary's fleet. The Nevian space-ship 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.
