"Never mind!" Ankova cut in. "I go! Many times I been to Mars. Give me plans. I go right away. I get them to fight."

Shelby drew from his sleeve pocket the black case containing information concerning the Atomic Ray which he had recovered from Hekalu Selba at the time of the Martian's capture. He opened it, and with his stylus added a brief message to the mass of notes inside, and wrote down the formula for a certain complex chemical compound. Then he handed the case to the Space Man.

"Take it to Alman Mak in the Checkald of Taboor if you can, Ankova. Good luck."

The son of the rebel chief hurried from the room with the missive in his hand. Shelby knew in his heart that to attempt to get Earth and Mars into action in time was a useless gesture, but he could not suppress a thrill of admiration for this wild son of the void. There was hard mettle in Ankova's makeup, hard and true. And most of them were like that—most of Telaba's men anyway.

"You two come with me," Telaba was saying. "We fight together. Put on space suits." He was tapping an instrument resembling a telegraph key. In unison with his movements the heavy signaling hammer sounded out orders and commands to his forces.


When the Earthians had eased themselves into their heavy protecting attire, Telaba led the way down a spiral stair and through an air lock, out into the open. Here everything was grim silent activity. Group after group of mounted Space Men poured skyward. Telaba's army was a mighty thing; with luck it might have beat down the resistance of either one of the two planets. But when compared with Alkebar's colossal horde, it paled into pitiful insignificance.

Nearby, a space disc, which must have measured fully two hundred feet in diameter, rested. The three mounted the light ladder which led to the interior.

In the metal walls were mounted two heat-ray projectors of Martian design, as well as several torpedo catapults and machine guns. Two Space Men were inspecting them.

Telaba signaled to the driver who knelt with lever in hand. The great disc trembled and the propelling force which no human being had yet learned how to produce, sent it and its burden hurtling toward the stars. The minions of the rebel chief circled and swirled about their commander's ship in wild soundless salute.
