he guards, taken completely by surprise, did not move. In a few moments they were bound, gagged, and dumped into a corner of 37X. Eager technies were swarming over the complicated mechanism that they had dared to touch, before, only for inspection and maintenance. The Frozen Gate was like a huge stopper in a bottle, made of chromium steel. It was thirty feet in diameter, and thirty feet thick from its well insulated inside face to that enigmatical Outside that had been a grisly mystery to the race for some five hundred centuries.
There was a flash of sparks, and the quiet hum of motors. With a shuddering groan the great plug freed itself from the grip of millennia; turned a few inches in its hole. The supporting gimbals took the load now, and slowly the great mass moved inward, carried by an overhead traveling crane whose track was bolted to the rock roof. The rate of movement was slow, not much over three or four inches a minute.
An excited murmur filled the cavern—almost hysterical joy. But Mich'l, watching that widening margin for the dreaded gush of liquid air, only trembled with relief. At least the calamity that had visited rash Atlantica would not be repeated here.
A young technie, one of the heat distributors, climbed up the heavy bosses on the gateway's face.
"I'm going to be the first to see the Sun!" he shouted joyously. His challenging gaze roved over the waiting crowd, and suddenly his face turned ashen. For at the turn of the corridor, some hundred yards away, he had seen men. No mistaking those uniforms; they were soldiers. And Mich'l, following his gaze, saw a riot-ray being wheeled into place. His own riot-ray already commanded the corridor, but he dared not use it. The soldiers, under the partial protection of the turn, could incinerate the helpless technies with little danger to themselves.
"Wait!" Mich'l shouted, running into the open.
n officer came to meet him. He then recognized Captain Ilgen, whose exceptional shrewdness had almost undone him before. Ilgen could not see the slow movement of the gate, and Mich'l, himself weaponless, counted only on parleying for time.
