"You will go to bed," directed Martin, crisply. "There will be lots of time for that work after you get rested up. The doctors have been reporting that the men who did not recover from the robots' broadcast are dying under this acceleration. With those facts staring us in the face, however, I do not see how we can reduce our power." "We can't. As it is, many more of us will probably die before we get away from the sun," and Stone staggered away, practically asleep on his feet. Day after day the frightful fall continued. The sun grew larger and larger, more and ever more menacingly intense. One by one at first, and then by scores, the mindless men of the Fleet died and were consigned to space--a man must be in full control of all his faculties to survive for long an acceleration of three gravities. * * * * * The generators of the defensive screens had early been tuned to neutralize as much as possible of Old Sol's most fervently harmful frequencies, and but for their mighty shields every man of the Fleet would have perished long since. Now even those ultra-powerful guards were proving inadequate. Refrigerators were running at the highest possible overload and the men, pressing as closely as possible to the dark sides of their vessels, were availing themselves of such extra protection of lead shields and the like as could be improvised from whatever material was at hand. Yet the already stifling air became hotter and hotter, eyes began to ache and burn, skins blistered and cracked under the punishing impact of forces which all the defenses could not block. But at last came the long-awaited announcement. "Pilots and watch-officers of all ships, attention!" the Chief Computer spoke into his microphone through parched and blackened lips. "We are now at the point of tangency. The gravity of the sun here is twenty-four point five meters per second squared. Since we are blasting twenty-nine point four we are beginning to pull away at an acceleration of four point nine. Until further notice keep your pointers directly away from the sun's center, in the plane of the Ecliptic." The sun was now in no sense the orb of day with which we upon Earth's green surface are familiar. It was a gigantic globe of turbulently seething flame, subtending an angle of almost thirty-five degrees, blotting out a full fourth of the cone of normally distinct vision. Sunspots were plainly to be seen; combinations of indescribably violent cyclonic storms and volcanic eruptions in a gaseously liquid medium of searing, eye-tearing incandescence. And everywhere, threatening at times even to reach the fiercely-struggling ships of space, were the solar prominences--fiendish javelins of frenziedly frantic destruction, hurling themselves in wild abandon out into the empty reaches of the void.
