CRASH!
Like a clap of thunder the noise reverberated through the metal hull of the sphere.
Kraag started violently, and only the bunk straps kept him from rocketing to the ceiling. Again:
CRASH!
And Kraag could feel the sphere shiver with the blow.
He switched on the lights just as another terrific crash sounded. This time he could see everything on the central deck quiver with the impact.
One of the four small ports around the central deck was uncovered, and the light threw a beam out into the black night of the asteroid. It brought a temporary cessation of the regular blows. During the interval, Kraag unstrapped himself and tumbled up to the control room, to switch on the communications system.
"Jonner!" he shouted. "Jonner, what in hell?"
"I'm not deaf," said the loudspeaker resentfully. "Give me a chance to turn down my volume, if you're going to holler."
"What the devil are you doing out there, Jonner?"
