There was a two-way, short-wave radio set built into his helmet. He reached up to adjust the switch, then flashed the alarm signal. A few seconds later he heard the answering voice of Portok the Martian, who was in command of the nearest of the Viking's exploring parties.

"Jumping ray-blasts, Chief, we were wondering what had happened to you!"

"Guide on my transmitter and get here as soon as you can!" Gerry snapped. "Hurry!"

A few minutes later they saw a glint of armor through the trees, and then the half dozen members of the exploring party emerged into the clearing. Their eyes were wide with surprise as they saw Closana standing beside Gerry.

"Who's your yellow-haired friend, Chief?" Portok asked with a broad grin. He had spoken in Martian, the two tongues being practically interchangeable with the men of the Interplanetary Fleet. Closana's eyes flashed fire.

"Speak of me with more respect, little Red-face!" she snapped. Portok's jaw sagged open, but before he could say anything further the underbrush on the far side of the clearing suddenly vomited a yelling horde of the Scaly Ones.

They came in close-packed masses, yelping shrilly. Their scaly skins and the blades of their swords gleamed in the subdued yellow light. Evidently bent on capture of the small group of strangers, they were not using their gas-guns.

"Keep together! Fall back toward the ship!" Gerry roared, drawing the sword he had captured earlier in the day.

There was a sharp crackle of ray-blasts as the Earth-men fell back before the charging horde of the Scaly Ones. The short hand-tubes were soon exhausted, but the heavy ray-guns carried by two of the men fired steadily. Murky light continually played about their stubby muzzles. Dozens of the Scaly Ones dropped, twitching, in the tall grass before the deadly blast of the rays, but the shouting hordes came on unchecked. And then a bugle sounded somewhere off on the flank!

"Now, you scaly devils!" Closana screamed, facing about and waving the sword high above her head, "The frontier guards have arrived!"
