THAT WORLDS MAY LIVE By NELSON S. BOND Not only the Solar System was involved in this war, but the entire universe; because of an old legendary secret--the mystery of Gog and Magog!

Lower away!" The great ship rocked and quivered as its jet rockets flared, forming a solid, cushioning pillar on which the _Spica_ lowered itself to the land cradle on Long Island Spaceport. "Tub!" muttered Flick Muldoon, and made a hasty grab for a case of equipment slithering across the deck. Gary Lane snapped, "Careful, Flick!" ... which was not like Lane. It was not his nature to be brusque. But now his voice, like his manner, was strained and unnatural. His eyes were tense as he glanced at his wrist chronometer. He sighed relievedly as the wallowing motion of the space-cruiser ended in a final, weary, convulsive heave. Blue uniformed attendants, luggage-laden, brushed by the pair of young scientists. Commands clacked with metallic authority from the brazen throats of deck audiophones. Locks wheezed asthmatically, and the warm, sweet fragrance of Earth air flooded through a nearby port. Flick drew a deep, contented breath. "Home again! Oh, boy! Linen suits instead of those damn bulgers ... sandals instead of lead boots ... breathable air instead of oxygen...." "... and," reminded Gary grimly, "a job of work to be done. Let's get going." His precious portfolio securely gripped in a bronzed fist, he strode to the gangway, stood there blinking momentarily in the pleasant sunlight of Earth. Then a warm hand was on his shoulder, and a friendly voice greeted him. The voice of his superior, Dr. Wade Bryant. "Welcome home, Gary! Have a good trip? Got lots of good shots, I hope--?" "I got," said Gary, "plenty! Dr. Bryant, we must go to the Observatory at once. If I'm not greatly mistaken, our expedition discovered something which will tear to bits every previous cosmological theory known to science. Wait till--" He stopped abruptly, silenced by the unexpected presence of a white-haired, cherubic little stranger beside his senior. "I--er--I don't believe I've had the pleasure--?" "No," chuckled Bryant. "But we'll soon remedy that. Professor Anjers, permit me to introduce my brilliant and indispensable young aide, Dr. Gary Lane. Gary, you've heard of Dr. Anjers, of course?" "Of course," replied Gary respectfully. "How do you do, sir?" But his mood had changed. His eagerness was gone; he seemed almost to wish to avoid further discussion. Bryant sensed this. He looked puzzled.
