He leaped to his feet and turned on his helmet phone full power.
"Hey, Commander!" he yelled. "Pardon me for asking, but how long would it take you to hurry? You'd better get here in five minutes or I'll be a mere hunk of dessert for these animated rock-piles. Step on those rockets!"

[1] Entities of silicon found only on the large asteroids. Almost human in shape and actions, they possess a silicic life-base rather than carbon, and remain a puzzle to scientists who have studied them. Being comparatively docile, reasonably intelligent, and tireless workers, they were originally brought to Earth for purposes of cheap labor. It was soon discovered, however, that they could be very dangerous. They possessed a fantastic and insatiable appetite for metal, and if not closely watched would destroy any with which they came in contact—first corroding it by means of peculiar crystalline emanations, and then digesting it. After some very calamitous experiences, the law was passed in 2139 forbidding any Silicytes being removed from the asteroids, on penalty of death.
