"Good-by, Joan," he whispered, and his muscles went taut. Urga paused, his weapon came up sharply. One little pressure, and-- * * * * * There was a commotion in the outer hall, the sound of padding feet. The four in the master room froze into immobility. Two Mercutian guards stumbled panting into the room. They came to a jerking halt, threw themselves prone upon the floor, arms outstretched in obeisance. "May we speak, oh Magnificent?" they asked humbly. "Say your say," the Viceroy said crossly. They rose to their feet heavily, and one of them spoke. "The Earth dogs are revolting. The Cors of the outlying districts report that the slaves are massing and are marching on Great New York. They are armed with Earth weapons. The Cor of the Third District reports two men responsible--one is a giant among them, almost as tall as our own kind; and the other a puny red-haired firebrand. The Cor has tried to capture them, but they are elusive. Even the search beams cannot disclose their hiding place." Hilary's heart gave a great bound. Grim and Wat had not waited then. The Viceroy's face darkened with anger. "The filthy scum," he growled; "this morning's lesson was not enough. This time I'll slay, burn, smash until there isn't a single rebel left. I'll fertilize their damned Earth with their own black blood. You, Cor Urga," he snapped, "transmit my orders to the Cors of the Hundreds. They are to mobilize their men at once, and proceed in accordance with instructions known to them as General Order One. All conveyors to be stopped except for troop movements. Every slave found with weapons, or acting suspiciously, to be slain on the spot. Flying patrols to scatter in pairs, observe for concentrations of slaves. Ray any gathering without warning. Inform Cor Algor of the _Tora_ (this was the great armed diskoid of the Mercutians that had previously reduced Great New York, Hilary found out afterwards) to resume his station over the city, ready to act when I give the signal." Even in the conflict of emotions, Hilary marveled at the unhesitating, snapped flow of orders. The Viceroy, in spite of his seeming gross lethargy, was a soldier, and an efficient one to boot. "Yes, Magnificent." Urga bowed low, and departed, thrusting a malignant glance at Hilary. * * * * * The Viceroy thrust off from him his bright yellow robes, wriggled his vast bulk swiftly into a close-fitting dull-gray tunic. To his belt he fastened little round knobs; the sun-tube dangled swankily at one side. He was accoutered for battle. He seemed to have forgotten the existence of the Earthlings. "You," he snapped to one of the waiting guards, "go to the laboratory at once; convey my strict orders to Cor Eela that the weather machine must function perfectly. There must be no slip-up--his life will answer for it." "Yes, oh Magnificence." The guard prostrated himself once more, then departed hastily.
