Like a cat, he bounced to his feet, crouching with Chan Dai's dart gun at his shoulder. A strangely grotesque heap was at his feet—Tom Fuller. Off there in the thinning mist he saw a shadowy figure and he fired at it twice. Whether his darts found their mark he was never to know, for a wall of white swept down suddenly to obscure his vision. Snow! Great massed flakes falling endlessly—the moisture of the mist crystallized and closing in on him to hide him even more safely, than had the mists themselves.
He was on his knees then at Fuller's side. A brilliant flash and a screaming roar over amongst the rocks apprised him of the fact that the guard's dart had gone wide. And yet Fuller was down, moaning with pain. Luke tried to turn him over and found that his body had taken on tremendous weight. He was flattened, crushed to the rocky surface of Vulcan by the full force of its gravity!
"What the devil!" he grunted as he heaved and strained. "What'd they do to you, old man?"
With great effort he succeeded in turning the scientist face up. Then he saw what had happened, and knew in a flash that Fuller had saved him from the singing dart whose energy was making a sizzling puddle of the stones where it had landed. The missile, in passing, had carried away the belt and part of the fabric of Tom's garment—carried away the capsule and the radium that energized it. Made the thing worse than useless. And Fuller had done this for him; he had flung himself upon Luke to shove him out of the line of fire ... risking his own life gladly ... lucky the deadly dart had missed his body, but....
"
You go on, Fenton," the scientist was whispering through lips that were blue and stiff. "Leave me here. I'm licked. But you can carry on the work; go to my friends and tell them—everything. Tell them what you saw back there—tell them——"
"Shut up!" Luke's words were softly growled. There was a new and utterly unaccountable huskiness in his voice as he straddled the prone body and locked his strong fingers underneath. "You ain't gonna be left behind," he grunted. "We're goin' on, brother, together."
His back straightened and Fuller was swung clear of the ground. His huge biceps tensed and the scrawny scientist was in the air, up and above the bowed head, then let down gently to rest across the broad shoulders of Luke Fenton. Fuller hung there, bent double by the immense weight of him, crushed to painful contact with the taut muscles that carried the strain.
On Earth, Fuller might have tipped the scales at a scant one hundred and thirty pounds; now his sagging body was a load in excess of seven hundredweight. With that load upon him, and glorying in the effort it cost, Luke staggered on toward the triple red glow, which, even in the blinding whiteness of the snowfall, marked the location of the columns of fire.
